1Use of the Endocuff during routine colonoscopy examination improves adenoma detection: A meta-analysis显示文摘AIM To perform meta-analysis of the use of Endocuff during average risk screening colonoscopy.METHODS Scopus, Cochrane databases, MEDLINE/Pub Med, and CINAHL were searched in April 2016. Abstracts from Digestive Disease Week, United European Gastroenterology, and the American College of Gastroenterology meeting were also searched from 2004-2015. Studies comparing EC-assisted colonoscopy(EAC) to standard colonoscopy, for any indication, were included in the analysis. The analysis was conducted by using the Mantel-Haenszel or DerS imonian and Laird models with the odds ratio(OR) to assess adenoma detection, cecal intubation rate, and complications performed. RESULTS Nine studies(n = 5624 patients) were included in the analysis. Compared to standard colonoscopy, procedures performed with EC had higher frequencies for adenoma(OR = 1.49, 95%CI: 1.23-1.80; P = 0.03), and sessile serrated adenomas detection(OR = 2.34 95%CI: 1.63-3.36; P < 0.001). There was no significant difference in cecal intubation rates between the EACgroup and standard colonoscopy(OR = 1.26, 95%CI: 0.70-2.27, I2 = 0%; P = 0.44). EAC was associated with a higher risk of complications, most commonly being superficial mucosal injury without higher frequency for perforation.CONCLUSION The use of an EC on colonoscopy appears to improve pre-cancerous polyp detection without any difference in cecal intubation rates compared to standard colonoscopy.Matthew Chin William Karnes M Mazen Jamal John G Lee Robert Lee Jason Samarasena Matthew L Bechtold Douglas L Nguyen 2016World Journal of Gastroenterology2016,22,43:4

10Endoscopic ultrasound-through-the-needle biopsy in pancreatic cystic lesions: A large single center experience显示文摘BACKGROUND Establishing a diagnosis of pancreatic cystic lesions(PCLs)preoperatively still remains challenging.Recently,endoscopic ultrasound(EUS)-through-the-needle biopsy(EUS-TTNB)using microforceps in PCLs has been made available.AIM To assess the efficacy and safety of EUS-TTNB in the diagnosis of PCLs.METHODS We retrospectively collected data of patients with PCLs who underwent both EUS-fine-needle aspiration(FNA)for cytology and EUS-TTNB at our institution since 2016.EUS-FNA for cytology was followed by EUS-TTNB in the same session.Evaluation of the cyst location,primary diagnosis,adverse events,and comparison between the cytologic fluid analyses and histopathology was performed.Technical success of EUS-TTNB was defined as visible tissue present after biopsy.Clinical success was defined as the presence of a specimen adequate to make a histologic or cytologic diagnosis.RESULTS A total of 56 patients(mean age 66.9±11.7,53.6%females)with PCLs were enrolled over the study period.The mean cyst size was 28.8 mm(12-85 mm).The EUS-TTNB procedure was technically successful in all patients(100%).The clinical success rate using EUS-TTNB was much higher than standard EUS-FNA,respectively 80.4%(45/56)vs 25%(14/56).Adverse events occurred in 2 patients(3.6%)who developed mild pancreatitis that resolved with medical therapy.Using TTNB specimens,23 of 32 cases(71.9%)with intraductal papillary mucinous neoplasm were further differentiated into gastric type(19 patients)and pancreaticobiliary type(4 patients)based on immunochemical staining.CONCLUSION EUS-TTNB for PCLs was technically feasible and had a favorable safety profile.Furthermore,the diagnostic yield for PCLs was much higher with EUS-TTNB than standard EUS-FNA cytology and fluid carcinoembryonic antigen.EUSTTNB should be considered as an adjunct to EUS-FNA and cytologic analysis in the diagnosis and management of PCLs.Rintaro Hashimoto John G Lee Kenneth J Chang Nabil El Hage Chehade Jason B Samarasena 2019World Journal of Gastrointestinal Endoscopy2019,11,11:0
11Lumen-apposing metal stents for benign gastrointestinal tract strictures: An international multicenter experience显示文摘AIM To investigate technical feasibility, outcomes and adverse events of the lumen-apposing metal stent(LAMS) for benign gastrointestinal(GI) tract strictures.METHODS Between July 2015 and January 2017, patients undergoing treatment by LAMS for benign GI strictures at three tertiary referral centers were included in this study. Primary outcomes included technical success, shortterm clinical success, long-term clinical success, and adverse events. Short-term clinical success was defined as symptom resolution at 30 d after stent placement. Longterm clinical success was defined by symptom resolution at 60 d in patients who continued to have indwelling stent, or continued symptom resolution at 30 d after elective stent removal.RESULTS A total of 21 patients(mean age 62.6 years, 47.6% males) underwent placement of LAMS for benign GI strictures. A 15 mm × 10 mm LAMS was placed in 16 patients, a 10 mm × 10 mm LAMS was placed in 2 patients, and a 16 mm × 30 mm LAMS was placed in 3 patients. Technical success was obtained in all cases. Short-term clinical success was achieved in 19 out of 21 cases(90.5%), and long-term clinical success was achieved in 12 out of 18(66.7%). Mean(range) stent indwell time was 107.2(28-370) d. After a mean(range) dwell time of 104.3(28-306) d, 9 LAMSs were removed due to the following complications: ulceration at stent site(n = 1), angulation(n = 2), migration(n = 4) and stricture overgrowth(n = 2). Migration occurred in 4 cases(19.0%), and it was associated with stricture resolution in one case. Median(range) follow-up period was 119(31-422) d. CONCLUSION Utilization of LAMS for benign strictures has shown to be technically feasible and safe, but adverse events highlight the need for further study of its indications.Javier Santos-Fernandez Christopher Paiji Mohammad Shakhatreh Irene Becerro-Gonzalez Ramon Sanchez-Ocana Paul Yeaton Jason Samarasena Manuel Perez-Miranda 2017World Journal of Gastrointestinal Endoscopy2017,9,12:0
