METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis.展开更多

METHODS: The prospective case-control study included 70 patients with postoperative ECFs with an output of < 500 mL/d, a fistulous tract of > 2 cm and without any local complication. They were divided into study (n = 23) and control groups (n = 47). Esophageal, gastric and colocutaneous fistulas were monitored under endoscopic visualization, which also allowed fibrin glue application directly through the external hole. Outcome variables included closure time, time to resume oral feeding and morbidity related to nutritional support. RESULTS: There were no differences in mean age, fistula output, and follow-up. Closure-time for all patients of the study group was 12.5 ± 14.2 d and 32.5 ± 17.9 d for the control group (P < 0.001), and morbidity related to nutritional support was 8.6% and 42.5%, respectively (P < 0.01). In patients with colonic fistulas, complete closure occurred 23.5 ± 19.5 d after the first application of fibrin glue, and spontaneous closure was observed after 36.2 ± 22.8 d in the control group (P = 0.36). Recurrences were observed in 2 patients because of residual disease. One patient of each group died during follow-up as a consequence of septic complications related to parenteral nutrition. CONCLUSION: Closure time was significantly reduced with the use of fibrin sealant, and oral feeding was resumed faster. We suggest the use of fibrin sealant for the management of stable enterocutaneous fistulas.展开更多

METHODS: Male Wistar rats were used as donors. Small bowels were retrieved, flushed and then stored in the respective 4 solutions for 18 h at 4℃. Functional integrity of the grafts was evaluated by isolated reperfusion with oxygenated Krebs-Henseleit buffer at 37℃ for 30 min in all 4 groups. RESULTS: Polysol preservation exhibited the highest tissue ATP concentration and the lowest release of LDH. Malondialdehyde, an index for tissue lipid peroxidation, was also the lowest in Polysol. Tissue oxygen consumption was significantly higher in Polysol than in the others. Of interest, UW-storage promoted 10-fold higher apoptosis than in the others. Moreover, electron microscopy revealed that the mucosal villi/micro-villi formation and the cell organelles, including mitochondria, were both significantly better preserved in Polysol, while deleterious alterations were apparent in the others, most notably in UW. Although Celsior and HTK exhibited the better trend of results than UW in some parameters, but could not reach the over-all superiority to UW.CONCLUSION: Cold storage using Polysol resulted in significantly better integrity and function of small bowel grafts than UW. Hence, Polysol may be a novel alternative for the small bowel preservation.展开更多

This study was conducted to report the outcome of surgical treatment of 634 cases of chronic PNS at a single institute between January 2001 and January 2010. Methods: Karydakis flap was performed in 244 patients (38.5%, Group 1). Excision and midline closure was performed in 371 patients (58.5%, Group 2), while the open method was used in 19 (3.0%). Data regarding patient and sinus characteristics, operative de-tails, postoperative course, complications and recurrence were recorded. Mean follow-up was 73.5 months. Results: 571 patients were male (90.1%) and 63 were female (9.9%). Their ages ranged between 16 - 44 years (mean 25.7 years). The mean body mass index was 31.2 (range 23.6 - 41.9), and 71.5% (453/634) were hirsute. Chronic PNS was the first presentation (primary) in 504 patients (79.5%) and recurrent in 130 (20.5%).Overall complication rate was 16.1% (102/ 634) and overall recurrence rate was 8.4% (53/634). Comparing both groups showed that they were similar regarding demographic characteristics, clinical presentation, hospital stay, healing time and time off work. Operative time was insignificantly longer with Karydakis technique (mean 43.2 versus 39.1 minutes, respectively). Complications were sig-nificantly more in patients with midline closure (21%, 78/371) as compared with Karydakis procedure (9%, 22/244) (P = 0.0001). Likewise, there was a significantly (P = 0.0001) higher rate of recurrence with midline closure (12.1%, 45/371) as opposed to Karydakis technique (2.5%, 6/244). Conclusions: 1) PNS affects mainly young male adults who are usually, obese and hirsute, 2) Karydakis technique for the management of chronic PNS, whether primary or recurrent, is a non-lengthy, efficient procedure that has less overall complications and a lower recurrence rate than conventional excision and midline closure.展开更多

The spasm of the internal sphincter seems to play an important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemorrhoidectomy in reducing the maximum resting pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward in all patients undergoing Milligan-Morgan hemorrhoidectomy. One group received an injection of 0.4 ml of saline into the internal anal sphincter, the other group were injected with 0.4 ml of soluti on containing 20 units of botulinum toxin. RESULTS: After five days from hemorrhoidectomy, maximum resting pressure decreased in the group injected with botulinum toxin and increased in the placebo group. The time of healing and postoperative pain when resting and during defecation significantly decreased in the group treated with an injection of botulinum toxin. CONCLUSIONS: Botulinum toxin injec tion into internal anal sphincter after hemorrhoidectomy is effective in reducin g maximum resting pressure, time of healing, and postoperative pain both on rest ing and during defecation in absence of complications or side effects.展开更多

文摘BACKGROUND Colorectal anastomotic leakage(CAL)is one of the most dreaded complications after colorectal surgery,with an incidence that can be as high as 27%.This event is associated with increased morbidity and mortality;therefore,its early diagnosis is crucial to reduce clinical consequences and costs.Some biomarkers have been suggested as laboratory tools for the diagnosis of CAL.AIM To assess the usefulness of plasma C-reactive protein(CRP)and calprotectin(CLP)as early predictors of CAL.METHODS A prospective monocentric observational study was conducted including patients who underwent colorectal resection with anastomosis,from March 2017 to August 2019.Patients were divided into three groups:G1–no complications;G2–complications not related to CAL;and G3–CAL.Five biomarkers were measured and analyzed in the first 5 postoperative days(PODs),namely white blood cell(WBC)count,eosinophil cell count(ECC),CRP,CLP,and procalcitonin(PCT).Clinical criteria,such as abdominal pain and clinical condition,were also assessed.The correlation between biomarkers and CAL was evaluated.Receiver operating characteristic(ROC)curve analysis was used to compare the accuracy of these biomarkers as predictors of CAL,and the area under the ROC curve(AUROC),specificity,sensitivity,positive predictive value,and negative predictive value(NPV)during this period were estimated.RESULTS In total,25 of 396 patients developed CAL(6.3%),and the mean time for this diagnosis was 9.0±6.8 d.Some operative characteristics,such as surgical approach,blood loss,intraoperative complications,and duration of the procedure,were notably related to the development of CAL.The length of hospital stay was markedly higher in the group that developed CAL compared with the group with complications other than CAL and the group with no complications(median of 21 d vs 13 d and 7 d respectively;P<0.001).For abdominal pain,the best predictive performance was on POD4 and POD5,with the largest AUROC of 0.84 on POD4.Worsening of the clinical condition was associated with the diagnosis of CAL,presenting a higher predictive effect on POD5,with an AUROC of 0.9.WBC and ECC showed better predictive effects on POD5(AUROC=0.62 and 0.7,respectively).Those markers also presented a high NPV(94%-98%).PCT had the best predictive effect on POD5(AUROC=0.61),although it presented low accuracy.However,this biomarker revealed a high NPV on POD3,POD4,and POD5(96%,95%,and 96%,respectively).The mean CRP value on POD5 was significantly higher in the group that developed CAL compared with the group without complications(195.5±139.9 mg/L vs 59.5±43.4 mg/L;P<0.00001).On POD5,CRP had a NPV of 98%.The mean CLP value on POD3 was significantly higher in G3 compared with G1(5.26±3.58μg/mL vs 11.52±6.81μg/mL;P<0.00005).On POD3,the combination of CLP and CRP values showed a high diagnostic accuracy(AUROC=0.82),providing a 5.2 d reduction in the time to CAL diagnosis.CONCLUSION CRP and CLP are moderate predictors of CAL.However,the combination of these biomarkers presents an increased diagnostic accuracy,potentially decreasing the time to CAL diagnosis.
文摘The pursuit of this paper is to collect principal reviews and systematic reviews about hyperthermic intraperitoneal chemotherapy(HIPEC) and cytoreductive surgery(CRS) used in colorectal cancer(CRC).We focus on principal biological aspects of CRC,hyperthermia effects,and surgical procedures.We searched PubMed/MEDLINE for the principal reviews and systematic reviews published from 2010 to 2021 regarding the bimodal treatment(CRS + HIPEC) against local and advanced CRC.In the literature,from several studies,it seems that the efficacy of bimodal treatment with an accurate CRS can extend overall survival.Despite these studies,there are not still any straight guidelines more detailed and scheduled about the use of combined treatment in patients with CRC.Even if the concept is still not very clear and shared,after a careful evaluation of the published data,and after some technical and pathophysiological descriptions,we concluded that it is possible to improve the overall survival and quality of life and to reduce the tumor relapse in patients affected by locally advanced(pT4) CRC with peritoneal metastases.
文摘The aim of this paper is to highlight the current development in the research field for helping people just exposed to Ebola virus survive(treatment) and to prevent the disease when given at various times after exposure(vaccine).Concerning the treatment,recombinant anti-Ebola monoclonal antibodies and small interfering RNAs that block the expression of essential viral proteins,are the most promising way in stopping the disease when it has already reached the humans.As far as concerns the prevention field,two candidate vaccines have clinical-grade vials available for phase 1 pre-licensure clinical trials,and demonstrated to have a 100%efficacy in studies on non human primates.Well-informed communities can reduce the main ways of spread the infection,by avoiding unprotected home-based care of people who are infected and also by completely modifying traditional burial practices that are way of diffusion of the contagion.
文摘Objectives: Different surgical techniques, with variable morbidity and recurrence rates, have been advocated for the management of chronic pilonidal sinus (PNS). This study was conducted to report the outcome of surgical treatment of 634 cases of chronic PNS at a single institute between January 2001 and January 2010. Methods: Karydakis flap was performed in 244 patients (38.5%, Group 1). Excision and midline closure was performed in 371 patients (58.5%, Group 2), while the open method was used in 19 (3.0%). Data regarding patient and sinus characteristics, operative de-tails, postoperative course, complications and recurrence were recorded. Mean follow-up was 73.5 months. Results: 571 patients were male (90.1%) and 63 were female (9.9%). Their ages ranged between 16 - 44 years (mean 25.7 years). The mean body mass index was 31.2 (range 23.6 - 41.9), and 71.5% (453/634) were hirsute. Chronic PNS was the first presentation (primary) in 504 patients (79.5%) and recurrent in 130 (20.5%).Overall complication rate was 16.1% (102/ 634) and overall recurrence rate was 8.4% (53/634). Comparing both groups showed that they were similar regarding demographic characteristics, clinical presentation, hospital stay, healing time and time off work. Operative time was insignificantly longer with Karydakis technique (mean 43.2 versus 39.1 minutes, respectively). Complications were sig-nificantly more in patients with midline closure (21%, 78/371) as compared with Karydakis procedure (9%, 22/244) (P = 0.0001). Likewise, there was a significantly (P = 0.0001) higher rate of recurrence with midline closure (12.1%, 45/371) as opposed to Karydakis technique (2.5%, 6/244). Conclusions: 1) PNS affects mainly young male adults who are usually, obese and hirsute, 2) Karydakis technique for the management of chronic PNS, whether primary or recurrent, is a non-lengthy, efficient procedure that has less overall complications and a lower recurrence rate than conventional excision and midline closure.
文摘PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play an important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemorrhoidectomy in reducing the maximum resting pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward in all patients undergoing Milligan-Morgan hemorrhoidectomy. One group received an injection of 0.4 ml of saline into the internal anal sphincter, the other group were injected with 0.4 ml of soluti on containing 20 units of botulinum toxin. RESULTS: After five days from hemorrhoidectomy, maximum resting pressure decreased in the group injected with botulinum toxin and increased in the placebo group. The time of healing and postoperative pain when resting and during defecation significantly decreased in the group treated with an injection of botulinum toxin. CONCLUSIONS: Botulinum toxin injec tion into internal anal sphincter after hemorrhoidectomy is effective in reducin g maximum resting pressure, time of healing, and postoperative pain both on rest ing and during defecation in absence of complications or side effects.

文摘Purpose:There is a common opinion that spinal fractures usually reflect the substantial impact of injuries and therefore may be used as a marker of significant associated injuries,specifically for intra-abdominal injury(IAI).The impact of concomitant spinal cord injury(SCI)with the risk of associated IAI has not been well clarified.The aim of this study was to evaluate the incidence and severity of IAIs in patients suffering from spinal fractures with or without SCI.Methods:A retrospective cohort study using the Israeli National Trauma Registry was conducted.Patients with thoracic,lumbar and thoracolumbar fractures resulting from blunt mechanisms of injury from January 1,1997 to December 31,2018 were examined,comparing the incidence,severity and mortality of IAIs in patients with or without SCI.The collected variables included age,gender,mechanism of injury,incidence and severity of the concomitant IAIs and pelvic fractures,abbreviated injury scale,injury severity score,and mortality.Statistical analysis was performed using GraphPad InStat?Version 3.10,with Chi-square test for independence and two sided Fisher’s exact probability test.Results:Review of the Israeli National Trauma Database revealed a total of 16,878 patients with spinal fractures.Combined thoracic and lumbar fractures were observed in 1272 patients(7.5%),isolated thoracic fractures in 4967 patients(29.4%)and isolated lumbar fractures in 10,639 patients(63.0%).The incidence of concomitant SCI was found in 4.95%(63/1272),7.65%(380/4967)and 2.50%(266/10639)of these patients,respectively.The overall mortality was 2.5%,proving higher among isolated thoracic fracture patient than among isolated lumbar fracture counterparts(11.3%vs.4.6%,p<0.001).Isolated thoracic fractures with SCI were significantly more likely to die than non-SCI counterparts(8.2%vs.3.1%,p<0.001).There were no differences in the incidence of IAIs between patients with or without SCI following thoracolumbar fractures overall or in isolated thoracic fractures;although isolated lumbar fractures patients with SCI were more likely to have renal(3.4%vs.1.6%,p=0.02)or bowel injuries(2.3%vs.1.0%,p=0.04)than the non-SCI counterparts.Conclusion:SCI in the setting of thoracolumbar fracture does not appear to be a marker for associated IAI.However,in a subset of isolated lumbar fractures,SCI patient is associated with increased risks for renal and bowel injury.
文摘This article reports two patients with hepatocellular carcinoma(HCC)and type 2 diabetes mellitus(T2DM),who showed marked changes in hepatocellular glycogen content.Periodic acid-Schiff(PAS)-positive and diastase-PAS-negative(glycogen-storing)hepatocytes were detected in both background liver parenchyma and in HCC tissues.In HCC tissues,the number of glycogen-storing cells resembling hepatocytes was considerably reduced and unevenly distributed as compared with hepatocytes in background liver.To be known,changes in hepatocellular glycogen content in T2DM patients have not been previously described.It is hypothesized that the reduction in glycogen content in both patients was likely associated with the emergence of Warburg type of glycolysis.
文摘Severe acute pancreatitis often leads to pancreatic and peripancreatic collections but,rarely,it can lead to collections at sites remote from the pancreas.Three male patients presented with abdominal pain and inguinoscrotal swelling.They were initially misdiagnosed with obstructed inguinal hernia,epididymo-orchitis and hydrocele,respectively.Later,their diagnosis of acute pancreatitis was revealed on laparotomy in one patient and on computed tomography(CT)in the remaining two patients.All these cases had extensive peripancreatic necrosis and paracolic collections tracking along the psoas muscle,downwards towards the pelvis.These collections were initially managed by percutaneous drainage and saline irrigation as a part of the‘step-up’approach.Two of these patients required open necrosectomy,while all required incision and drainage of inguinoscrotal collections.All the patients were discharged in satisfactory condition.Inguinoscrotal swelling is unusual as a first presentation of acute pancreatitis.A high index of suspicion,with careful study of patient’s history and examination along with CT,may provide an accurate diagnosis.Local drainage may be required to control sepsis and also provide an egress route for intra-abdominal collections.
