CE, SBE, or SBE with prior CE was performed in 401, 353, and 47 patients, respectively. Data from clinical and endoscopy records were collected for analysis. Indications, procedure times, diagnostic yields, and complications were summarized and evaluated.RESULTS The overall diagnostic yield for the CE group was 57.6%. The diagnostic yield of CE in patients with obscure gastroin testinal bleeding(OGIB) was significantly greater than that in patients with no bleeding(70.5% vs 43.8%, P < 0.01). The overall diagnostic yield of SBE was 69.7%. There was no difference in the diagnostic yield of SBE between patients with OGIB and those with no bleeding(72.5% vs 68.9%, P = 0.534). Forty-seven patients underwent CE prior to SBE. Among them, the diagnostic yield of SBE with positive findings on prior CE was 93.3%. In addition, SBE detected two cases with superficial ulcer and erosive lesions in the small bowel, which were missed by CE. However, one case with lymphoma and two with Crohn's disease were not confirmed by SBE. The rate of capsule retention was 2.0%. There were no significant complications during or after SBE examinations.CONCLUSION SBE is a safe and effective technique for diagnosing small bowel diseases. SBE with prior CE seemed to improve the diagnostic yield of small bowel diseases.展开更多

Patients with this condition are often poor candidates for surgical bypasses, and placement of self-expanding metal stent(SEMS) can be technically challenging. In this study, we examined the feasibility of combined application of single-balloon enteroscope(SBE) and colonoscope for SEMS placement in patients with malignant small intestinal obstruction. Thirty-four patients were enrolled in this study, among which 22 patients received SEMS placement by using SBE and colonoscope, while the other 12 patients received conservative medical treatment. The patients were followed up for one year. Stent placement was technically feasible in 95.5%(21/22). Clinical improvement was achieved in 86.4%(19/22). For the 19 clinical success cases, the average time of benefits from a gastric outlet obstruction scoring system(GOOSS) increase ≥1 was 111.9±89.5 days. For the 12 patients receiving conservative medical treatment, no significant improvement in GOOSS score was observed. Moreover, a significant increase of Short-Form-36 health survey score was observed in the 19 patients at time of 30 days after stent placement. By Kaplan-Meier analysis, a significant survival improvement was observed in patients with successful SEMS placement, compared with patients receiving conservative medical treatment. Taken together, combined use of SBE and colonoscope makes endoscopic stent placement feasible in patients with malignant small intestinal obstruction, and patients can benefit from it in terms of prolonged survival and improved quality of life.展开更多

METHODS: A retrospective review of 136 rS BE procedures performed at a tertiary academic referral center from January 2006 and September 2013 was completed. Patient characteristics including age, gender and inpatient status were collected. The indication for the procedure was categorized into one of three groups: Obscure gastrointestinal bleeding(GIB), evaluation for Crohn's disease and abnormal imaging. Procedural characteristics including insertion depth(ID), procedure time, concordance with pre-procedural imaging and complications were also recorded. Lastly, DY, defined as the percentage of cases producing either a definitive diagnosis or findings that could explain clinical symptoms and therapeutic yield(TY), defined as the percentage of cases in which a definitive intervention was performed, were determined. Mucosal tattooing and biopsy alone were not included in the TY. RESULTS: A total of 136 rS BE procedures were identified. Mean patient age was 57.5(± 16.2) years, 67(49.2%) were male, and 110(80.9%) procedures were performed on an outpatient basis. Indications for rS BE included GIB in 55(40.4%), evaluation of inflammatory bowel disease(IBD) in 29(21.3%), and imaging suggestive of pathology other than GIB or IBD in 43(31.6%). Nine(6.6%) rS BEs were performed for other indications. Mean ID was 68.3(± 39.3) cm proximal to the ileocecal valve and mean time to completion was 41.7(± 15.5) min. Overall, 73(53.7%) cases were diagnostic and 25(18.4%) cases were therapeutic in which interventions(argon plasma coagulation, stricture dilatation, polypectomy, etc.) were performed. Pre-procedural imaging was performed in 88(64.7%) patients. Endoscopic concordance of positive imaging findings was seen in 31(35.2%) cases. Follow up data was available in 93(68.4%) patients; 2(2.2%) reported post-procedural abdominal pain within 30 d following rS BE. There were no other reported complications. CONCLUSION: rS BE exhibits an acceptable diagnostic and TY, rendering it a safe and effective procedure for the evaluation and treatment of small bowel diseases.展开更多

Howev...The single-balloon enteroscopy(SBE) system was launched in 2007, proposed as a simpler method than double-balloon enteroscopy(DBE). Controversy surrounds whether the SBE system has the same insertability as DBE. However, many methods have been proposed to improve the depth of insertion with the SBE system, involving several techniques and endoscopic accessories. SBE is used for investigating not only small bowel diseases, but also diseases of the pancreatobiliary and colonic structures. SBE is a necessary advancement for many endoscopic procedures and applications in modern clinical practice. In our review, we summarized the current literature concerning the insertability of SBE and described the technical aspects of improving the rate of deep insertion in SBE procedures. In addition, the recent applications of SBE to diseases besides those of the small bowel are described.展开更多

Literature data on how to address this problem are limited. Here, we report on a case of massive stomach bleeding with MIC that was successfully treated endoscopically using an overtube of singleballoon enteroscopy.CASE SUMMARY A 62-year-old gentleman with metastatic lung cancer was admitted to the intensive care unit due to tarry stools and hematemesis of 1500 mL of blood during hospitalization. Emergent esophagogastroduodenoscopy revealed massive blood clots and fresh blood in the stomach with evidence of active bleeding.Bleeding sites could not be observed even by changing the patient’s position and aggressive endoscope suction. The MIC was successfully removed using an overtube connected with a suction pipe, which was inserted into the stomach with an overtube of a single-balloon enteroscope. An ultrathin gastroscope was also introduced through the nose into the stomach to guide the suction. A massive blood clot was successfully removed, and an ulcer with oozing bleeding at the inferior lesser curvature of the upper gastric body was revealed, facilitating endoscopic hemostatic therapy.CONCLUSION This technique appears to be a previously unreported method to suction MIC out of the stomach in patients with acute upper gastrointestinal bleeding. This technique could be considered when other methods are not available or if they fail to remove massive blood clots in the stomach.展开更多

METHODS: Between August 2008 and June 2010, patients in whom total colonoscopy failed within 30 min of insertion were assigned randomly to undergo either SBC or DBC. No sedatives were used. After the endoscopy, all patients were asked to evaluate pain during the procedure on a 10-point analog scale (1 = no pain; 10 = worst imaginable pain) with a questionnaire. The study outcomes were the cecal intubation rate and time, endoscopic findings, complications, and pain score. RESULTS: The SBC and DBC groups included 11 and 10 patients, respectively. All but one SBC patient achieved total colonoscopy successfully. The cecal intubation times were 18 min (range: 10-85 min) and 12.8 min (range: 9.5-42 min) in the SBC and DBC groups, respectively (P= 0.17). No difference was observed in the prevalence of colon polyps between the SBC and DBC groups (45% vs 30%, P = 0.66). SBC showed advanced colon cancer in the ascending colon, which was inaccessible using conventional colonoscopy. The respective pain scores were 5 (1-10) [median (range)] and 5 (1-6) in the SBC and DBC groups (P = 0.64). No complications were noted in any patient. CONCLUSION: The utility of singleand double-balloon endoscopy for colonoscopy seems comparable in patients with incomplete colonoscopy using a conventional colonoscope.展开更多

文摘AIM To evaluate diagnostic yields of capsule endoscopy(CE) and/or single-balloon enteroscopy(SBE) in patients with suspected small bowel diseases.METHODS Were trospectively analyzed 700 patients with suspected small bowel diseases from September 2010 to March 2016. CE, SBE, or SBE with prior CE was performed in 401, 353, and 47 patients, respectively. Data from clinical and endoscopy records were collected for analysis. Indications, procedure times, diagnostic yields, and complications were summarized and evaluated.RESULTS The overall diagnostic yield for the CE group was 57.6%. The diagnostic yield of CE in patients with obscure gastroin testinal bleeding(OGIB) was significantly greater than that in patients with no bleeding(70.5% vs 43.8%, P < 0.01). The overall diagnostic yield of SBE was 69.7%. There was no difference in the diagnostic yield of SBE between patients with OGIB and those with no bleeding(72.5% vs 68.9%, P = 0.534). Forty-seven patients underwent CE prior to SBE. Among them, the diagnostic yield of SBE with positive findings on prior CE was 93.3%. In addition, SBE detected two cases with superficial ulcer and erosive lesions in the small bowel, which were missed by CE. However, one case with lymphoma and two with Crohn's disease were not confirmed by SBE. The rate of capsule retention was 2.0%. There were no significant complications during or after SBE examinations.CONCLUSION SBE is a safe and effective technique for diagnosing small bowel diseases. SBE with prior CE seemed to improve the diagnostic yield of small bowel diseases.

文摘Small intestinal obstruction is a common complication of primary gastrointestinal cancer or metastatic cancers. Patients with this condition are often poor candidates for surgical bypasses, and placement of self-expanding metal stent(SEMS) can be technically challenging. In this study, we examined the feasibility of combined application of single-balloon enteroscope(SBE) and colonoscope for SEMS placement in patients with malignant small intestinal obstruction. Thirty-four patients were enrolled in this study, among which 22 patients received SEMS placement by using SBE and colonoscope, while the other 12 patients received conservative medical treatment. The patients were followed up for one year. Stent placement was technically feasible in 95.5%(21/22). Clinical improvement was achieved in 86.4%(19/22). For the 19 clinical success cases, the average time of benefits from a gastric outlet obstruction scoring system(GOOSS) increase ≥1 was 111.9±89.5 days. For the 12 patients receiving conservative medical treatment, no significant improvement in GOOSS score was observed. Moreover, a significant increase of Short-Form-36 health survey score was observed in the 19 patients at time of 30 days after stent placement. By Kaplan-Meier analysis, a significant survival improvement was observed in patients with successful SEMS placement, compared with patients receiving conservative medical treatment. Taken together, combined use of SBE and colonoscope makes endoscopic stent placement feasible in patients with malignant small intestinal obstruction, and patients can benefit from it in terms of prolonged survival and improved quality of life.
文摘AIM: To evaluate the technical success, diagnostic yield(DY) and therapeutic potential of retrograde single balloon enteroscopy(rS BE). METHODS: A retrospective review of 136 rS BE procedures performed at a tertiary academic referral center from January 2006 and September 2013 was completed. Patient characteristics including age, gender and inpatient status were collected. The indication for the procedure was categorized into one of three groups: Obscure gastrointestinal bleeding(GIB), evaluation for Crohn's disease and abnormal imaging. Procedural characteristics including insertion depth(ID), procedure time, concordance with pre-procedural imaging and complications were also recorded. Lastly, DY, defined as the percentage of cases producing either a definitive diagnosis or findings that could explain clinical symptoms and therapeutic yield(TY), defined as the percentage of cases in which a definitive intervention was performed, were determined. Mucosal tattooing and biopsy alone were not included in the TY. RESULTS: A total of 136 rS BE procedures were identified. Mean patient age was 57.5(± 16.2) years, 67(49.2%) were male, and 110(80.9%) procedures were performed on an outpatient basis. Indications for rS BE included GIB in 55(40.4%), evaluation of inflammatory bowel disease(IBD) in 29(21.3%), and imaging suggestive of pathology other than GIB or IBD in 43(31.6%). Nine(6.6%) rS BEs were performed for other indications. Mean ID was 68.3(± 39.3) cm proximal to the ileocecal valve and mean time to completion was 41.7(± 15.5) min. Overall, 73(53.7%) cases were diagnostic and 25(18.4%) cases were therapeutic in which interventions(argon plasma coagulation, stricture dilatation, polypectomy, etc.) were performed. Pre-procedural imaging was performed in 88(64.7%) patients. Endoscopic concordance of positive imaging findings was seen in 31(35.2%) cases. Follow up data was available in 93(68.4%) patients; 2(2.2%) reported post-procedural abdominal pain within 30 d following rS BE. There were no other reported complications. CONCLUSION: rS BE exhibits an acceptable diagnostic and TY, rendering it a safe and effective procedure for the evaluation and treatment of small bowel diseases.
文摘The single-balloon enteroscopy(SBE) system was launched in 2007, proposed as a simpler method than double-balloon enteroscopy(DBE). Controversy surrounds whether the SBE system has the same insertability as DBE. However, many methods have been proposed to improve the depth of insertion with the SBE system, involving several techniques and endoscopic accessories. SBE is used for investigating not only small bowel diseases, but also diseases of the pancreatobiliary and colonic structures. SBE is a necessary advancement for many endoscopic procedures and applications in modern clinical practice. In our review, we summarized the current literature concerning the insertability of SBE and described the technical aspects of improving the rate of deep insertion in SBE procedures. In addition, the recent applications of SBE to diseases besides those of the small bowel are described.
文摘Gallstone-induced ileus is a rare complication of cholelithiasis.Since localization of gallstones impacted in the small bowel,especially in the ileum,prevents access by conventional endoscopy in most cases,the mainstay of treatment remains surgical.Recent invention of double-and single-balloon enteroscopy has added much to the ability of imaging the small bowel and enables endoscopically directed therapy.Herein,for the first time,we report a successful endoscopic calculus removal via peroral single-balloon enteroscopy in an 81-year-old woman suffering from gallstone ileus of the ileum.
文摘AIM:To evaluate the clinical usefulness of singleballoon endoscopy(SBE) in patients in whom a colonoscope was technically difficult to insert previously.METHODS:The study group comprised 15 patients(8 men and 7 women) who underwent SBE for colonoscopy(30 sessions).The number of SBE sessions was 1 in 7 patients,2 in 5 patients,3 in 1 patient,4 in 1 patient,and 6 in 1 patient.In all patients,total colonoscopy was previously unsuccessful.The reasons for difficulty in scope passage were an elongated colon in 6 patients,severe intestinal adhesions after open surgery in 4,an elongated colon and severe intestinal adhesions in 2,a left inguinal hernia in 2,and multiple diverticulosis of the sigmoid colon in 1.Three endoscopists were responsible for SBE.The technique for inserting SBE in the colon was basically similar to that in the small intestine.The effectiveness of SBE was assessed on the basis of the success rate of total colonoscopy and the presence or absence of complications.We also evaluated the diagnostic and treatment outcomes of colonoscopic examinations with SBE.RESULTS:Total colonoscopy was successfully accomplished in all sessions.The mean insertion time to the cecum was 22.9 ± 8.9 min(range 9 to 40).Abnormalities were found during 21 sessions of SBE.The most common abnormality was colorectal polyps(20 sessions),followed by radiation colitis(3 sessions) and diverticular disease of the colon(3 sessions).Colorectal polyps were resected endoscopically in 15 sessions.A total of 42 polyps were resected endoscopically,using snare polypectomy in 32 lesions,hot biopsy in 7 lesions,and endoscopic mucosal resection in 3 lesions.Fifty-six colorectal polyps were newly diagnosed on colonoscopic examination with SBE.Histopathologically,these lesions included 2 intramucosal cancers,42 tubular adenomas,and 2 tubulovillous adenomas.The mean examination time was 48.2 ± 20.0 min(range 25 to 90).Colonoscopic examination or endoscopic treatment with SBE was not associated with any serious complications.CONCLUSION:SBE is a useful and safe procedure in patients in whom a colonoscope is technically difficult to insert.
文摘BACKGROUND Double-balloon,single-balloon,and spiral enteroscopy(DBE,SBE,and SE)have revolutionized the management of intestinal diseases.However,evidence about efficacies of these methods is lacking.We aimed to conduct a meta-analysis comparing the clinical outcomes among DBE,SBE,and SE.METHODS We searched randomized controlled trials and prospective studies in MEDLINE,PubMed,EMBASE,Cochrane Library,and Chinese CQVIP database.Studies referencing the comparison of at least two of these three methods were included.Primary outcome was diagnostic yield.Other outcomes were therapeutic yield,total enteroscopy,examination time,time to maximum insertion,and depth of maximal insertion(DMI).RESULTS Eleven studies including 727 patients were identified:DBE vs SE(n=6),DBE vs SBE(n=4),and SBE vs SE(n=1).The diagnostic and therapeutic yields did not differ significantly when comparing DBE with SE[odds ratio(OR)=1.19,95%confidence interval(CI):0.68-2.08;OR=1.17,95%CI:0.61-2.23]and DBE with SBE(OR=0.85,95%CI:0.55-1.33;OR=1.71,95%CI:0.64-4.60).Total enteroscopy,examination time,time to maximum insertion,and DMI were similar between SBE and DBE.DBE was superior to SE with regard to DMI[mean difference(MD)=36.76,95%CI:5.09-68.43],with longer time to maximum insertion(MD=15.14,95%CI:12-18.27)and examination time(MD=12.98,95%CI:9.57-16.38).CONCLUSION DBE and SBE have similar clinical outcomes.Compared with DBE,SE seems to have similar diagnostic and therapeutic yields,but shorter procedural time in cost of less depth of insertion.SE needs further evaluation vs SBE.DBE is recommended for complete enteroscopy.
文摘BACKGROUND Computed tomography(CT)small bowel three-dimensional(3D)reconstruction is a powerful tool for the diagnosis of small bowel disease and can clearly show the intestinal lumen and wall as well as the outside structure of the wall.The horizontal axis position can show the best adjacent intestinal tube and the lesion between the intestinal tubes,while the coronal position can show the overall view of the small bowel.The ileal end of the localization of the display of excellent,and easy to quantitative measurement of the affected intestinal segments,the sagittal position for the rectum and the pre-sacral lesions show the best,for the discovery of fistulae is also helpful.Sagittal view can show rectal and presacral lesions and is useful for fistula detection.It is suitable for the assessment of inflammatory bowel disease,such as assessment of disease severity and diagnosis and differential diagnosis of the small bowel and mesenteric space-occupying lesions as well as the judgment of small bowel obstruction points.CASE SUMMARY Bleeding caused by small intestinal polyps is often difficult to diagnose in clinical practice.This study reports a 29-year-old male patient who was admitted to the hospital with black stool and abdominal pain for 3 months.Using the combination of CT-3D reconstruction and capsule endoscopy,the condition was diagnosed correctly,and the polyps were removed using single-balloon enteroscopyendoscopic retrograde cholangiopancreatography without postoperative complications.CONCLUSION The role of CT-3D in gastrointestinal diseases was confirmed.CT-3D can assist in the diagnosis and treatment of gastrointestinal diseases in combination with capsule endoscopy and small intestinal microscopy.
文摘BACKGROUND Lymphangiomas in the gastrointestinal tract are extremely rare in adults.As a benign lesion,small intestine lymphangiomas often remain asymptomatic and pose challenges for definitive diagnosis.However,lymphangiomas can give rise to complications such as abdominal pain,bleeding,volvulus,and intussusception.Here,we report a case of jejunal cavernous lymphangioma that presented with intermittent melena and refractory anemia in a male adult.CASE SUMMARY A 66-year-old man presented with intermittent melena,fatigue and refractory anemia nine months prior.Esophagogastroduodenoscopy and colonoscopy were performed many times and revealed no apparent bleeding.Conservative management,including transfusion,hemostasis,gastric acid secretion inhibition and symptomatic treatment,was performed,but the lesions tended to recur shortly after surgery.Ultimately,the patient underwent capsule endoscopy,which revealed a more than 10 cm lesion accompanied by active bleeding.After singleballoon enteroscopy and biopsy,a diagnosis of jejunal cavernous lymphangioma was confirmed,and the patient underwent surgical resection.No complications or recurrences were observed postoperatively.CONCLUSION Jejunal cavernous lymphangioma should be considered a cause of obscure gastrointestinal bleeding.Capsule endoscopy and single-balloon enteroscopy can facilitate diagnosis.Surgical resection is an effective management method.
文摘BACKGROUND Small bowel tumors(SBTs)are a heterogeneous group of difficult-to-diagnose tumors that account for 2%-5%of all gastrointestinal tumors.Single-balloon enteroscopy greatly enhances the diagnosis and treatment of SBTs.However,few epidemiological studies have been conducted in Taiwan to determine the clinical profile of SBTs.AIM To investigate the clinical characteristics,managements and prognosis of SBTs in a medical center in Taiwan.METHODS The study enrolled 51 patients aged 58.9±8.8 years(range,22-93)diagnosed with SBTs from November 2009 to July 2021.We retrospectively recorded clinical characteristics,indications,endoscopic findings,pathological results,management,and outcomes for further analysis.RESULTS A male preponderance was observed(56.8%).The most common indications were suspected small intestinal tumors(52.9%)and obscure gastrointestinal bleeding(39.2%).The most common tumor location was the ileum(41.2%).The performance of imaging studies(P=0.004)and the types of findings(P=0.005)differed significantly between malignant and benign SBTs.The most frequent imaging finding was a small intestinal mass(43.1%).The top three malignant tumor types were gastrointestinal stromal tumors(GISTs),adenocarcinomas,and lymphomas.Moreover,the proportions of benign and malignant tumors were 27.5%and 72.5%,respectively.The survival rates of patients with malignant tumors in the GIST and non-GIST groups differed significantly(P=0.015).Kaplan–Meier survival analysis showed a significant difference in survival between patients in the malignant and benign groups(P=0.04).All patients with lymphoma underwent chemotherapy(n=7/8,87.5%),whereas most patients with GISTs underwent surgery(n=13/14,92.8%).CONCLUSION Patients with GISTs have a significantly higher survival rate than those with other malignant SBTs.Therefore,a large-scale nationwide study is warranted to evaluate the population-based epidemiology of SBTs.
文摘Background and aim:Double-balloon enteroscopy(DBE)and single-balloon enteroscopy(SBE)are new techniques capable of providing deep enteroscopy.Results of individual studies comparing these techniques have not been able to identify a superior strategy.Our aim was to systematically pool all available studies to compare the efficacy and safety of DBE with SBE for evaluation of the small bowel.Methods:Databases were searched,including PubMed,Embase,and the Cochrane Central Register of Controlled Trials.The main outcome measures were complete small-bowel visualization,diagnostic yield,therapeutic yield,and complication rate.Statistical analysis was performed using Review Manager(RevMan version 5.2).Meta-analysis was performed using fixed-effect or random-effect methods,depending on the absence or presence of significant heterogeneity.We used the v2 and I2 test to assess heterogeneity between trials.Results were expressed as risk ratios(RR)or mean differences with 95%confidence intervals(CI).Results:Four prospective,randomized,controlled trials with a total of 375 patients were identified.DBE was superior to SBE for visualization of the entire small bowel[pooled RR=0.37(95%CI:0.19–0.73;P=0.004)].DBE and SBE were similar in ability to provide diagnosis[pooled RR=0.95(95%CI:0.77–1.17;P=0.62)].There was no significant difference between DBE and SBE in therapeutic yield[pooled RR=0.78(95%CI:0.59–1.04;P=0.09)]and complication rate[pooled RR=1.08(95%CI:0.28–4.22);P=0.91].Conclusions:DBE was superior to SBE with regard to complete small bowel visualization.DBE was similar to SBE with regard to diagnostic yield,ability to provide treatment and complication rate,but these results should be interpreted with caution as they is based on very few studies and the overall quality of the evidence was rated as low tomoderate,due to the small sample size.
文摘Backgrounds:At present,there is no consensus on the induction methods in term pregnancy with borderline oligohydramnios.This study aimed to compare the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter(SBC)in term nulliparous women with borderline oligohydramnios.Methods:We conducted a retrospective cohort study from January 2016 to November 2018.During the study period,a total of 244 cases were enrolled.Of these,103 cases were selected for induction using dinoprostone and 141 cases were selected for induction with SBC.The pregnancy outcomes between the two groups were compared.Primary outcomes were successful vaginal delivery rates.Secondary outcomes were maternal and neonatal adverse events.Multivariate logistic regression was used to assess the risk factors for vaginal delivery failure in the two groups.Results:The successful vaginal delivery rates were similar between the dinoprostone group and the SBC group(64.1%[66/103]vs.59.6%,[84/141]P=0.475),even after adjustment for potential confounding factors(adjusted odds ratio[aOR]:1.07,95%confidence interval[CI]:0.57-2.00,P=0.835).The incidence of intra-amniotic infection was lower in the dinoprostone group than in the SBC group(1.9%[2/103]vs.7.8%[11/141],P<0.001),but the presence of non-reassuring fetal heart rate was higher in the dinoprostone group than in the SBC group(12.6%[13/103]vs.0.7%,[1/141]P<0.001).Multivariate logistic regression showed that nuchal cord was a risk factor for vaginal delivery failure after induction with dinoprostone(aOR:6.71,95%CI:1.96-22.95).There were three factors related to vaginal delivery failure after induction with SBC,namely gestational age(aOR:1.51,95%CI:1.07-2.14),body mass index(BMI)>30 kg/m^(2)(aOR:2.98,95%CI:1.10-8.02),and fetal weight>3500 g(aOR:2.49,95%CI:1.12-5.50).Conclusions:Term nulliparous women with borderline oligohydramnios have similar successful vaginal delivery rates after induction with dinoprostone or SBC,with their advantages and disadvantages.In women with nuchal cord,the risk of vaginal delivery failure is increased if dinoprostone is used in the induction of labor.BMI>30 kg/m^(2),large gestational age,and estimated fetal weight>3500 g are risk factors for vaginal delivery failure after induction with SBC.

文摘BACKGROUND Massive intragastric clotting(MIC) makes endoscopic therapy difficult in patients with acute upper gastrointestinal bleeding. Literature data on how to address this problem are limited. Here, we report on a case of massive stomach bleeding with MIC that was successfully treated endoscopically using an overtube of singleballoon enteroscopy.CASE SUMMARY A 62-year-old gentleman with metastatic lung cancer was admitted to the intensive care unit due to tarry stools and hematemesis of 1500 mL of blood during hospitalization. Emergent esophagogastroduodenoscopy revealed massive blood clots and fresh blood in the stomach with evidence of active bleeding.Bleeding sites could not be observed even by changing the patient’s position and aggressive endoscope suction. The MIC was successfully removed using an overtube connected with a suction pipe, which was inserted into the stomach with an overtube of a single-balloon enteroscope. An ultrathin gastroscope was also introduced through the nose into the stomach to guide the suction. A massive blood clot was successfully removed, and an ulcer with oozing bleeding at the inferior lesser curvature of the upper gastric body was revealed, facilitating endoscopic hemostatic therapy.CONCLUSION This technique appears to be a previously unreported method to suction MIC out of the stomach in patients with acute upper gastrointestinal bleeding. This technique could be considered when other methods are not available or if they fail to remove massive blood clots in the stomach.

文摘AIM: To compare the utility of single-balloon colonoscopy (SBC) or double-balloon colonoscopy (DBC) for difficult colonoscopies. METHODS: Between August 2008 and June 2010, patients in whom total colonoscopy failed within 30 min of insertion were assigned randomly to undergo either SBC or DBC. No sedatives were used. After the endoscopy, all patients were asked to evaluate pain during the procedure on a 10-point analog scale (1 = no pain; 10 = worst imaginable pain) with a questionnaire. The study outcomes were the cecal intubation rate and time, endoscopic findings, complications, and pain score. RESULTS: The SBC and DBC groups included 11 and 10 patients, respectively. All but one SBC patient achieved total colonoscopy successfully. The cecal intubation times were 18 min (range: 10-85 min) and 12.8 min (range: 9.5-42 min) in the SBC and DBC groups, respectively (P= 0.17). No difference was observed in the prevalence of colon polyps between the SBC and DBC groups (45% vs 30%, P = 0.66). SBC showed advanced colon cancer in the ascending colon, which was inaccessible using conventional colonoscopy. The respective pain scores were 5 (1-10) [median (range)] and 5 (1-6) in the SBC and DBC groups (P = 0.64). No complications were noted in any patient. CONCLUSION: The utility of singleand double-balloon endoscopy for colonoscopy seems comparable in patients with incomplete colonoscopy using a conventional colonoscope.
文摘BACKGROUND Blue rubber bleb nevus syndrome(BRBNS)is a rare vascular disease,difficult to diagnose and choose a treatment method,especially in young children.There are several limiting factors to the use of enteroscopy for diagnostics and treatment in pediatric patients,in general.The literature on BRBNS cases is limited and presents various therapeutic approaches.CASE SUMMARY We present here a case of BRBNS involving a 4-year-old female,whose intestinal venous lesions were successfully treated by endoscopic sclerotherapy and aethoxysklerol foam.Skin lesions,typical for BRBNS,appeared on the 8th d of the child’s life and their number increased over the next several months.The child also experienced episodes of critical decrease in hemoglobin level(by as much as 52 g/L)for several years,requiring iron supplementation and several blood transfusions.Video capsule endoscopy revealed numerous vascular formations in the small bowel.The combined findings of gastrointestinal venous formations and skin lesions prompted BRBNS diagnosis.Single-balloon enteroscopy was used to perform sclerotherapy,with aethoxysklerol foam.A positive effect was observed within 19 mo of follow-up.We continue to monitor the patient’s hemoglobin level,every 2 wk,and it has remained satisfactory(>120 g/L).CONCLUSION Endoscopic sclerotherapy can be effective in the clinical management of gastrointestinal manifestations of BRBNS in young children.
