OBI was determined by the HBV-DNA amplification of at least two different sets of primers by TaqM an realtime polymerase chain reaction. Possibly carcinogenetic factors such as alcohol abuse, diabetes mellitus, obesity and non-alcoholic steatohepatitis(NASH) were examined. Surgical outcomes were evaluated according to diseasefree survival(DFS), overall survival(OS) and diseasespecific survival(DSS).RESULTS OBI was found in 27/78 patients(34.6%) with NBNC HCC. The OBI patients were significantly younger than the non-OBI cases at the time of surgery(average age 63.0 vs 68.1, P = 0.0334) and the OBI cases overlapped with other etiologies significantly more frequently compared to the non-OBI cases(P = 0.0057). OBI had no impact on the DFS, OS or DSS. Only tumorrelated factors affected these surgical outcomes.CONCLUSION Our findings indicate that OBI had no impact on surgical outcomes. The surgical outcomes of NBNC HCC depend on early tumor detection; this reconfirms the importance of a periodic medical examination for individuals who have NBNC HCC risk factors.展开更多

Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced? tip(n=207) or the IPS using the 30-degree Kelman? tip(n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis(NS) grade, cumulated dissipated energy(CDE), preoperative corrected distance visual acuity(CDVA), and CDVA at one month were recorded. RESULTS: CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS(n=70) compared with IPS(n=44)(P=0.010). Surgical complications were not statistically different between the two subcohorts(P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs(VOs) at one month for NS grade III and above cataracts were-0.17 log MAR(6/4.5) in the CPS and-0.15 log MAR(6/4.5) in the IPS subcohort respectively(P=0.033).CONCLUSION: CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei.展开更多

Obesity is intuitively considered a risk factor for increased post-hepatectomy morbidity and mortality. Nevertheless, peer-reviewed literature reveals significant heterogeneity between different cohorts contributing to varying conclusions. Outcomes in this cohort for Laparoscopic Liver Resection (LLR), especially in non-academic settings remain under-evaluated. The current study evaluated outcomes of LLR in obese patients, in a community health system. Methods: A retrospective analysis of all patients undergoing LLR at the flagship hospital in the community health system, between 2013 and 2020, was performed. Classified into two groups based on Body Mass Index (BMI): obese (BMI > 30 kg/m<sup>2</sup>) vs non-obese (BMI Results: 90 patients underwent LLR during the 7-year period;obese = 38 and non-obese = 52. No statistically significant differences were noted between obese and non-obese cohorts, in baseline characteristics including age (53.1 ± 15.1 vs 56.8 ± 11.6 years), female gender (60.5% vs 53.8%), and ASA grade (3.13 ± 0.53 vs 3.02 ± 0.54) (all p > 0.05). Univariate analysis showed no statistically significant differences between obese and non-obese groups, comparing estimated blood loss [300 (100 - 500) vs. 200 (100 - 462.5) cc], operative time [177 (125 - 215) vs. 150.9 (111 - 207) minutes], bile leak (2.6% vs. 4.1%), post-operative bleeding (2.6% vs. 4.1%), infection (0% vs. 4.1%), cardiorespiratory complication (10.5% vs 12.2%), conversion rate (5.3% vs 5.8%), length of stay [4 (3 - 5) vs. 4 (2 - 5) days], 90-day reoperation (0% vs. 2%) and 90-day readmission (2.6% vs. 4.1%) (p > 0.05). Multivariate analysis showed no association between obesity and composite complication rate (p = 0.97), after adjusting for alcohol abuse, neoadjuvant therapy, and prior liver surgery. Conclusion: LLR is a key technique that can be replicated in the community setting to improve outcomes in obese patients requiring liver resection. Larger prospective multicenter studies are warranted to externally validate these findings.展开更多

Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P < 0.05; range, 0.0010.017) increased peritoneal perforation rates. It was shown that older age increased cyst dimensions, and presence of multiple and bilobar cysts increased intrabiliary rupture rates (P < 0.05; range, 0.0010.028). Partial pericystectomy and drainage was the most frequent surgical procedure in all groups (71.6%). The incidence of postoperative complications in the peritoneal perforated group, in the intrabiliary ruptured group, and in the noncomplicated group was 25%, 16.1% and 5.5%, respectively. When compared, complication rates were significantly different (P = 0.002). When length of hospital stay was compared, there was no signif icant difference between the groups (P > 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree.展开更多

Measurement of HRQOL is now clearly a mandatory component in evaluating interventions and management of medical and surgical diseases. In designing comprehensive and meaningful clinical studies particular attention ought to be made of measures of HRQOL. This is clearly very important in inflammatory bowel disease. Both ulcerative colitis (UC) and Crohn’s disease (CD) have a major impact on HRQOL. The chronic and unrelenting nature of these diseases, the often early age of onset, and the impact on social and sexual aspects of life significantly change patient’s perception, body image and quality of life. This manuscript is an overview of the available published data on HRQOL in UC and CD patients focusing on the impact of surgical therapy. While these two diseases may have some similarities in their management, clearly their impact on quality of life and the effects of are significantly different. Hence we are presenting the data separately.展开更多

This has improved outcome in many surgical specialties, including breast surgery. We present the surgical outcome of breast cancer (BC) patients treated over a 12-month period following the principle of ERAS protocols and highlight the underpinning evidence. Methods: A retrospective analysis of all BC patients diagnosed and had breast cancer surgery over 12 months. Data collected included patient’s demographics, type of surgery, LOS, other perioperative care and significant postoperative complications. Excluded were patients with bilateral cancer surgeries, diagnostic excision, margin clearance or breast reconstruction. Results: There were 621 BC diagnosed including 5 male and 12 bilateral female BC. The ages ranged from 25 to 93 years. Excluding bilateral BC, 351 patients (70.2 %) had breast conserving surgery (BCS) while 149 (29.8%) patients had mastectomy as index cancer surgery. Sixteen (4.5%) of the women who initially underwent BCS subsequently had a completion mastectomy. The overall rate of successful BCS was 335/500 (67%). 441 (85.5%) of patients were discharged same or next day. 12 (7.2%) cases of postoperative haematoma, 6 cases of wound infection and a case of seroma requiring surgical/radiological drainage recorded. Conclusion: ERAS protocol in BC surgery is associated with decreased LOS and low complication rate. Delayed discharges are mostly due to adverse social factors and medical comorbidity rather than post-operative surgical complications.展开更多

Methods: Results of 124 eyes of 115 patients who had a diagnosis of distal obstruction of the lacrimal drainage system and underwent transcanalicular laser dacryocystorhinostomy procedures were retrospectively detected. Initial 50 eyes were considered as group 1;74 following eyes were accepted as group 2. Groups were compared regarding age, gender, total surgical time, time for creation of osteotomy, pain score, bleeding score, anatomic and functional success rates. Results: The average total surgical time was 43.2 ± 6.0 minutes (range: 31 to 65 minutes) in group 1, and 30.0 ± 6.4 minutes (range: 21 to 57 minutes) in group 2 (p < 0.001). Laser osteotomy creation required 25.0 ± 4.2 minutes (range: 14 to 34 minutes) in group 1, and 14.6 ± 3.6 months (range: 9 to 28 minutes) (p < 0.001). Intraoperative pain and bleeding scores were significantly better in group 2 (p < 0.001 and p < 0.001 respectively). Success rate was 54.0% in group 1, and 85.1% in group 2 (p < 0.001). Conclusion: The results of current study clearly showed that increased experience of a surgeon results with improvement of better surgical outcomes. Initial studies about a novel technique should make clear if the study cases are the beginning cases of the authors.展开更多

文摘The detrimental effects of both diabetes mellitus(DM)and hyperglycemia in the perioperative period are well established and have driven extensive efforts to control blood glucose concentration(BGC)in a variety of clinical settings.It is now appreciated that acute BGC spikes,hypoglycemia,and high glycemic variability(GV)lead to more endothelial dysfunction and oxidative stress than uncomplicated,chronically elevated BGC.In the perioperative setting,fasting is the primary approach to reducing the risk for pulmonary aspiration;however,prolonged fasting drives the body into a catabolic state and therefore may increase GV.Elevated GV in the perioperative period is associated with an increased risk for postoperative complications,including morbidity and mortality.These challenges pose a conundrum for the management of patients typically instructed to fast for at least 8 h before surgery.Preliminary evidence suggests that the administration of an oral preoperative carbohydrate load(PCL)to stimulate endogenous insulin production and reduce GV in the perioperative period may attenuate BGC spikes and ultimately decrease postoperative morbidity,without significantly increasing the risk of pulmonary aspiration.The aim of this scoping review is to summarize the available evidence on the impact of PCL on perioperative GV and surgical outcomes,with an emphasis on evidence pertaining to patients with DM.The clinical relevance of GV will be summarized,the relationship between GV and postoperative course will be explored,and the impact of PCL on GV and surgical outcomes will be presented.A total of 13 articles,presented in three sections,were chosen for inclusion.This scoping review concludes that the benefits of a PCL outweigh the risks in most patients,even in those with well controlled type 2 DM.The administration of a PCL might effectively minimize metabolic derangements such as GV and ultimately result in reduced postoperative morbidity and mortality,but this remains to be proven.Future efforts to standardize the content and timing of a PCL are needed.Ultimately,a rigorous data-driven consensus opinion regarding PCL administration that identifies optimal carbohydrate content,volume,and timing of ingestion should be established.
文摘AIM:To describe the clinical characteristics and surgical outcomes of complicated cataract with pediatric trematodal granulomatous uveitis(TGU).METHODS:Patients of cataract with TGU in the membranous(inactive) stage underwent cataract surgery with intraocular lens(IOL) implantation.Preoperative history and ophthalmic examination were conducted for all cases,whereas Schimphlug imaging and corneal topography were done for some patients.Postoperative follow up was done on the 1st,2nd,and 5th postoperative days after surgery.Then,it was done at least at one,three,and six months postoperatively.Intraoperative and postoperative complications and the methods of their management were reported.RESULTS:Twelve eyes of 12 male children were included in this study ranging from 8 to 16y.The mean best corrected Snellen visual acuity(BCVA) was significantly improved from 0.09±0.06 preoperatively to 0.37±0.11 at the final visit 6mo postoperatively(P<0.001).Schimphlug imaging and corneal topography showed flattening of the anterior surface of the inferior cornea.Intraoperative difficulties and complications included the poor dilatability of the drown down pupil,strong posterior synechia between the anterior lens capsule and the iris at the site of the inferior retrocorneal vascularized membrane and hyphema.All cases underwent primary hydrophobic IOL implantation.CONCLUSION:Surgery for this type of cataract is relatively safe and effective.It is associated with some specific difficulties and complications that should be considered during surgery and follow up.
文摘Postoperative sleep disturbance is a common occurrence with significant adverse effects on patients including delayed recovery,impairment of cognitive function,pain sensitivity and cardiovascular events.The development of postoperative sleep disturbance is multifactorial and involves the surgical inflammatory response,the severity of surgical trauma,pain,anxiety,the use of anesthetics and environmental factors such as nocturnal noise and light levels.Many of these factors can be managed perioperatively to minimize the deleterious impact on sleep.Pharmacological and non-pharmacological treatment strategies for postoperative sleep disturbance include dexmedetomidine,zolpidem,melatonin,enhanced recovery after surgery(ERAS) protocol and controlling of environmental noise and light levels.It is likely that a combination of pharmacological and non-pharmacological therapies will have the greatest impact;however,further research is required before their use can be routinely recommended.
文摘AIM To investigate the prevalence, clinicopathological characteristics and surgical outcomes of occult hepatitis B virus(HBV) infection(OBI) in patients with non-B, non-C(NBNC) hepatocellular carcinoma(HCC).METHODS This study retrospectively examined the cases of 78 NBNC patients with curative resection for HCC for whom DNA could be extracted from formalin-fixed paraffin-embedded tissue. OBI was determined by the HBV-DNA amplification of at least two different sets of primers by TaqM an realtime polymerase chain reaction. Possibly carcinogenetic factors such as alcohol abuse, diabetes mellitus, obesity and non-alcoholic steatohepatitis(NASH) were examined. Surgical outcomes were evaluated according to diseasefree survival(DFS), overall survival(OS) and diseasespecific survival(DSS).RESULTS OBI was found in 27/78 patients(34.6%) with NBNC HCC. The OBI patients were significantly younger than the non-OBI cases at the time of surgery(average age 63.0 vs 68.1, P = 0.0334) and the OBI cases overlapped with other etiologies significantly more frequently compared to the non-OBI cases(P = 0.0057). OBI had no impact on the DFS, OS or DSS. Only tumorrelated factors affected these surgical outcomes.CONCLUSION Our findings indicate that OBI had no impact on surgical outcomes. The surgical outcomes of NBNC HCC depend on early tumor detection; this reconfirms the importance of a periodic medical examination for individuals who have NBNC HCC risk factors.
文摘AIM: To evaluate surgical outcomes(SOs) and visual outcomes(VOs) in cataract surgery comparing the Centurion? phacoemulsification system(CPS) with the Infiniti? phacoemulsification system(IPS).METHODS: Prospective, consecutive study in a singlesite private practice. Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced? tip(n=207) or the IPS using the 30-degree Kelman? tip(n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis(NS) grade, cumulated dissipated energy(CDE), preoperative corrected distance visual acuity(CDVA), and CDVA at one month were recorded. RESULTS: CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS(n=70) compared with IPS(n=44)(P=0.010). Surgical complications were not statistically different between the two subcohorts(P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs(VOs) at one month for NS grade III and above cataracts were-0.17 log MAR(6/4.5) in the CPS and-0.15 log MAR(6/4.5) in the IPS subcohort respectively(P=0.033).CONCLUSION: CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei.

文摘AIM:To compare the surgical outcomes of a multifocal intraocular lens(IOL;Lentis Comfort LS-313 MF15)with those of an enhanced monofocal IOL(Tecnis Eyhance DIB00V).METHODS:This retrospective study included patients who underwent cataract surgery with LS-313 MF15 or Eyhance IOL implantation.Data regarding patient demographics,surgical records,and ophthalmic examination before the cataract surgery and one and three months postoperatively were collected.Visual acuities,refractive values,defocus curves,contrast sensitivities and subjective symptoms were evaluated.RESULTS:Among the 71 eyes(47 patients)included in this study,32 eyes(20 patients)underwent LS-313 MF15 IOL implantation,and 39 eyes(27 patients)underwent Eyhance IOL implantation.No significant differences were observed in age,axial length,or refractive error between the two groups preoperatively.Furthermore,the distancecorrected and uncorrected distance visual acuities one month postoperatively did not differ between the groups,and both groups had sufficient visual acuities at the distances of 5,1 m,70,50,and 30 cm.Other ophthalmic data,including subjective symptoms based on the 14-item Visual Function Index Questionnaire,monocular defocus curves,contrast sensitivities,and halo and glare,did not differ between the groups three months postoperatively.Moreover,both groups had good outcomes.The spherical equivalent one month postoperatively was significantly myopic in the LS-313 MF15 group compared with that in the Eyhance group(P=0.033);however,this difference was not observed three months postoperatively(P=0.471).CONCLUSION:Comparison of the surgical outcomes of LS-313 MF15 with those of Eyhance with different optical properties reveal that both IOLs show good postoperative outcomes,with no significant differences being noted between the two IOLs.
文摘OBJECTIVE To compare the outcomes of transapical transcatheter aortic valve replacement(TA-TAVR)and surgical aortic valve replacement(SAVR)using a large US population sample.METHODS The U.S.National Inpatient Sample was queried for all patients who underwent TA-TAVR or SAVR during the years2016-2017.The primary outcome was all-cause in-hospital mortality.Secondary outcomes were in-hospital stroke,pericardiocentesis,pacemaker insertion,mechanical ventilation,vascular complications,major bleeding,acute kidney injury,length of stay,and cost of hospitalization.Outcomes were modeled using multi-variable logistic regression for binary outcomes and generalized linear models for continuous outcomes.RESULTS A total of 1560 TA-TAVR and 44,280 SAVR patients were included.Patients who underwent TA-TAVR were older and frailer.Compared to SAVR,TA-TAVR correlated with a higher mortality(4.5%vs.2.7%,effect size(SMD)=0.1)and higher periprocedural complications.Following multivariable analysis,both TA-TAVR and SAVR had a similar adjusted risk for in-hospital mortality.TA-TAVR correlated with lower odds of bleeding with(adjusted OR(aOR)=0.26;95%CI:0.18-0.38;P<0.001),and a shorter length of stay(adjusted mean ratio(aMR)=0.77;95%CI:0.69-0.84;P<0.001),but higher cost(aMR=1.18;95%CI:1.10-1.28;P<0.001).No significant differences in other study outcomes.In subgroup analysis,TA-TAVR in patients with chronic lung disease had higher odds for mortality(aOR=3.11;95%CI:1.37-7.08;P=0.007).CONCLUSION The risk-adjusted analysis showed that TA-TAVR has no advantage over SAVR except for patients with chronic lung disease where TA-TAVR has higher mortality.

文摘BACKGROUND Endoscopic submucosal dissection(ESD)and transanal endoscopic submucosal dissection(TES)are widely employed surgical techniques.However,the comparative efficacy and safety of both remain inconclusive.AIM To comprehensively analyze and discern differences in surgical outcomes between ESD and TES.METHODS We conducted a systematic search of the electronic databases PubMed,Embase,Cochrane Central Register of Controlled Trials,Scopus,and CINAHL from inception till August 2023.We analyzed outcomes including recurrence rate,en bloc resection,R0 resection rate,perforation rate,procedure length,and hospital stay length applying a random-effects inverse-variance model.We assessed publication bias by conducting an Egger’s regression test and sensitivity analyses.RESULTS We pooled data from 11 studies involving 1013 participants.We found similar recurrence rates,with a pooled odds ratio of 0.545(95%CI:0.176-1.687).En bloc resection,R0 resection,and perforation rate values were also similar for both ESD and TES.The pooled analysis for procedure length indicated a mean difference of-4.19 min(95%CI:-22.73 to 14.35),and the hospital stay was on average shorter for ESDs by about 0.789 days(95%CI:-1.671 to 0.093).CONCLUSION Both ESD and TES displayed similar efficacy and safety profiles across multiple outcomes.Our findings show that individualized patient and surgeon preferences,alongside specific clinical contexts,can be considered when selecting between these two techniques.
文摘The era of geriatric surgery has arrived with increased global life expectancy.The need to optimize outcomes in this group of patients goes beyond traditional outcomes such as postoperative morbidity and mortality indicators.Recognizing risk factors that impact adverse surgical outcomes such as frailty and sarcopenia,individualizing optimization strategies such as prehabilitation and a multidisciplinary geriatric surgical service have been shown to improve postoperative outcomes and help the older surgical patient regain premorbid function and maintain quality of life.There needs to be a concerted effort to increase awareness of this increasingly important topic in practicing surgeons around the world to meet the challenges of the aging population.
文摘Introduction: Obesity is associated with an increased risk of fatty liver disease, predisposing to liver fibrosis and cirrhosis, as well as increased occurrence of hepatocellular carcinoma. Obesity is intuitively considered a risk factor for increased post-hepatectomy morbidity and mortality. Nevertheless, peer-reviewed literature reveals significant heterogeneity between different cohorts contributing to varying conclusions. Outcomes in this cohort for Laparoscopic Liver Resection (LLR), especially in non-academic settings remain under-evaluated. The current study evaluated outcomes of LLR in obese patients, in a community health system. Methods: A retrospective analysis of all patients undergoing LLR at the flagship hospital in the community health system, between 2013 and 2020, was performed. Classified into two groups based on Body Mass Index (BMI): obese (BMI > 30 kg/m<sup>2</sup>) vs non-obese (BMI Results: 90 patients underwent LLR during the 7-year period;obese = 38 and non-obese = 52. No statistically significant differences were noted between obese and non-obese cohorts, in baseline characteristics including age (53.1 ± 15.1 vs 56.8 ± 11.6 years), female gender (60.5% vs 53.8%), and ASA grade (3.13 ± 0.53 vs 3.02 ± 0.54) (all p > 0.05). Univariate analysis showed no statistically significant differences between obese and non-obese groups, comparing estimated blood loss [300 (100 - 500) vs. 200 (100 - 462.5) cc], operative time [177 (125 - 215) vs. 150.9 (111 - 207) minutes], bile leak (2.6% vs. 4.1%), post-operative bleeding (2.6% vs. 4.1%), infection (0% vs. 4.1%), cardiorespiratory complication (10.5% vs 12.2%), conversion rate (5.3% vs 5.8%), length of stay [4 (3 - 5) vs. 4 (2 - 5) days], 90-day reoperation (0% vs. 2%) and 90-day readmission (2.6% vs. 4.1%) (p > 0.05). Multivariate analysis showed no association between obesity and composite complication rate (p = 0.97), after adjusting for alcohol abuse, neoadjuvant therapy, and prior liver surgery. Conclusion: LLR is a key technique that can be replicated in the community setting to improve outcomes in obese patients requiring liver resection. Larger prospective multicenter studies are warranted to externally validate these findings.
文摘AIM: To evaluate the predisposing factors for peritoneal perforation and intrabiliary rupture and the effects of these complications on surgical outcome in liver hydatid disease.METHODS: A total of 372 patients with liver hydatid cysts who had undergone surgical treatment were evaluated retrospectively. Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P < 0.05; range, 0.0010.017) increased peritoneal perforation rates. It was shown that older age increased cyst dimensions, and presence of multiple and bilobar cysts increased intrabiliary rupture rates (P < 0.05; range, 0.0010.028). Partial pericystectomy and drainage was the most frequent surgical procedure in all groups (71.6%). The incidence of postoperative complications in the peritoneal perforated group, in the intrabiliary ruptured group, and in the noncomplicated group was 25%, 16.1% and 5.5%, respectively. When compared, complication rates were significantly different (P = 0.002). When length of hospital stay was compared, there was no signif icant difference between the groups (P > 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree.
文摘Over the past 30 years, health related quality of life (HRQOL) has developed into a scientific index of subjective health status. Measurement of HRQOL is now clearly a mandatory component in evaluating interventions and management of medical and surgical diseases. In designing comprehensive and meaningful clinical studies particular attention ought to be made of measures of HRQOL. This is clearly very important in inflammatory bowel disease. Both ulcerative colitis (UC) and Crohn’s disease (CD) have a major impact on HRQOL. The chronic and unrelenting nature of these diseases, the often early age of onset, and the impact on social and sexual aspects of life significantly change patient’s perception, body image and quality of life. This manuscript is an overview of the available published data on HRQOL in UC and CD patients focusing on the impact of surgical therapy. While these two diseases may have some similarities in their management, clearly their impact on quality of life and the effects of are significantly different. Hence we are presenting the data separately.
文摘Background: ERAS protocols are perioperative interventions aimed at reducing postoperative complications, length of hospital stay (LOS) and early return to normal activities. This has improved outcome in many surgical specialties, including breast surgery. We present the surgical outcome of breast cancer (BC) patients treated over a 12-month period following the principle of ERAS protocols and highlight the underpinning evidence. Methods: A retrospective analysis of all BC patients diagnosed and had breast cancer surgery over 12 months. Data collected included patient’s demographics, type of surgery, LOS, other perioperative care and significant postoperative complications. Excluded were patients with bilateral cancer surgeries, diagnostic excision, margin clearance or breast reconstruction. Results: There were 621 BC diagnosed including 5 male and 12 bilateral female BC. The ages ranged from 25 to 93 years. Excluding bilateral BC, 351 patients (70.2 %) had breast conserving surgery (BCS) while 149 (29.8%) patients had mastectomy as index cancer surgery. Sixteen (4.5%) of the women who initially underwent BCS subsequently had a completion mastectomy. The overall rate of successful BCS was 335/500 (67%). 441 (85.5%) of patients were discharged same or next day. 12 (7.2%) cases of postoperative haematoma, 6 cases of wound infection and a case of seroma requiring surgical/radiological drainage recorded. Conclusion: ERAS protocol in BC surgery is associated with decreased LOS and low complication rate. Delayed discharges are mostly due to adverse social factors and medical comorbidity rather than post-operative surgical complications.

文摘Aim:The goal of this research was to create a mathematical model to evaluate the short-term effectiveness of laparoscopic and robotic surgeries and to apply this model to surgeries with laparoscopic and robotic variants to evaluate their performance.Materials and methods:A mathematical model was developed in this study to compare the short-term effectiveness of six different surgical procedures:ventral hernia repairs,hysterectomies,lung lobectomies,pancreatectomies,gastric bypass,and prostatectomies.The criteria analyzed to compare these procedures included morbidity rate,readmission rate,mortality rate,cost,length of hospitalization and operative time.These criteria were scaled based on their significance when considering a surgery,such that more important criteria,those that directly impact patient health,are more heavily weighted than less important criteria.Results:The mathematical model indicated that robotic surgery was the preferred option for lung lobectomies and prostatectomies.Laparoscopy was preferred for all other procedures.In the case of gastric bypass,laparoscopy was heavily preferred,and there was only a marginal preference in laparoscopy for hysterectomies and ventral hernia repairs.Conclusion:The mathematical model developed in this research serves as a robust definitive standard that can continue to be utilized to compare robotic and laparoscopic surgeries.With new technologies,preferences are likely to change in favor of robotic surgery,and this model can be employed to predict the impact of those advancements.
文摘Purpose: To compare perioperative and postoperative outcomes of the first and following 50 cases of transcanalicular laser dacryocystorhinostomy performed by a surgeon team. Methods: Results of 124 eyes of 115 patients who had a diagnosis of distal obstruction of the lacrimal drainage system and underwent transcanalicular laser dacryocystorhinostomy procedures were retrospectively detected. Initial 50 eyes were considered as group 1;74 following eyes were accepted as group 2. Groups were compared regarding age, gender, total surgical time, time for creation of osteotomy, pain score, bleeding score, anatomic and functional success rates. Results: The average total surgical time was 43.2 ± 6.0 minutes (range: 31 to 65 minutes) in group 1, and 30.0 ± 6.4 minutes (range: 21 to 57 minutes) in group 2 (p < 0.001). Laser osteotomy creation required 25.0 ± 4.2 minutes (range: 14 to 34 minutes) in group 1, and 14.6 ± 3.6 months (range: 9 to 28 minutes) (p < 0.001). Intraoperative pain and bleeding scores were significantly better in group 2 (p < 0.001 and p < 0.001 respectively). Success rate was 54.0% in group 1, and 85.1% in group 2 (p < 0.001). Conclusion: The results of current study clearly showed that increased experience of a surgeon results with improvement of better surgical outcomes. Initial studies about a novel technique should make clear if the study cases are the beginning cases of the authors.
文摘In the last 10 years,surgery has been developing towards minimal invasiveness;therefore,robotic surgery represents the consequent evolution of laparoscopic surgery.Worldwide,surgeons’performances have been upgraded by the ergonomic developments of robotic systems,leading to several benefits for patients.The introduction into the market of the new Da Vinci Xi system has made it possible to perform all types of surgery on the colon,an in selected cases,to combine interventions in other organs or viscera at the same time.Optimization of the suprapubic surgical approach may shorten the length of hospital stay for patients who undergo robotic colonic resection.From this perspective,single-port robotic colectomy,has reduced the number of robotic ports needed,allowing a better anesthetic outcome and faster recovery.The introduction on the market of new surgical robotic systems from multiple manufacturers is bound to change the landscape of robotic surgery and yield high-quality surgical outcomes.
文摘AIM:To compare surgical outcomes of phacoemulsification combined with glaucoma surgical techniques performed with either Kahook Dual Blade(KDB)or iStent for Japanese patients with either primary open angle glaucoma or exfoliation glaucoma.METHODS:We retrospectively evaluated the surgical outcomes of 129 eyes of 84 Japanese patients with glaucoma who underwent KDB or 44 eyes of 34 patients who underwent phacoemulsification with iStent procedures combined with cataract surgery.The primary outcome was surgical success or failure[with surgical failure being indicated by<20%reduction from preoperative intraocular pressure(IOP)or IOP>18 mm Hg as criterion A;IOP>14 mm Hg as criterion B on two consecutive study visits;or reoperation requirement].In addition,we assessed the number of postoperative glaucoma medications and the resulting complications.RESULTS:The probability of success was significantly higher in the KDB group than in the iStent group for criterion A(60.2%vs 46.4%,P=0.019).In the KDB group,the mean preoperative IOP of 19.8±7.3 mm Hg decreased significantly to 13.0±3.1 mm Hg(P<0.01),and the mean number of glaucoma medications at 2.5±1.4 decreased significantly to 1.6±1.6(P<0.01)12 mo postoperatively.In the iStent group,the mean preoperative IOP of 17.8±2.9 mm Hg significantly decreased to 14.3±2.3 mm Hg(P<0.01),and the mean number of glaucoma medications at 2.2±1.1 decreased significantly to 0.9±1.4(P<0.01)12 mo postoperatively.The overall IOP reduction percentage was higher in the KDB group(26.2%)than in the iStent group(19.0%)12 mo postoperatively(P=0.03).Hyphema occurred significantly more frequently in the KDB group(16.3%)than in the iStent group(2.3%,P=0.017).CONCLUSION:KDB and iStent procedures combined with cataract surgery both result in significant IOP and glaucoma medication reductions after the 12-month followup.The patients in the KDB group have a higher success rate for the target IOP of less than 18 mm Hg and a higher complication rate than those in the iStent group.
