Kenneth Barshop, Field F Willingham, William R Brugge, Lawrence R Zukerberg, Braden Kuo
BACKGROUND AND AIMS: Patients with chronic constipation or motility disorders may be referred for rectal suction biopsy (RSB) to rule out Hirschsprung's disease (HD). RSB may not be successful beyond infancy due to the increased thickness of rectal mucosa. Endoscopic mucosal resection (EMR) could improve the diagnostic yield for HD when compared with traditional RSB because of the larger and deeper samples acquired for analysis. METHODS: In this prospective, single-center study, patients referred for RSB were offered enrollment for concurrent EMR...

BACKGROUND AND AIMS: During endoscopic full-thickness resection (EFTR) for cancers, whether exposure of the lumen to the abdominal cavity during the procedure is acceptable is controversial because of the potential risk of tumor cell seeding. To assess the possibility of transplantation due to contact with tumor cells during the procedure, we prospectively investigated the ability of cancer cells to be detached by touching the tumor surface. METHODS: In 48 patients with a single early gastric cancer resected by endoscopic submucosal dissection, stamp cytology was performed by touching the surface of the specimens to glass slides...

BACKGROUND AND AIMS: There is uncertainty regarding the optimal management of endoscopically invisible ("flat") low grade dysplasia in ulcerative colitis. Such a finding does not currently provide an automatic indication for colectomy; however, a recommendation of surveillance instead of surgery is controversial. The aim of this study was to determine the clinical and cost-effectiveness of colonoscopic surveillance versus colectomy for endoscopically invisible low-grade dysplasia of the colon in ulcerative colitis...

BACKGROUND & AIMS: Inadequate polypectomy leads to incomplete resection, interval colorectal cancer, and adverse events. However, polypectomy competency is rarely reported and quality metrics are lacking. The primary aims of this study were to (1) assess polypectomy competency among a cohort of gastroenterologists, and (2) measure the correlation between polypectomy competency and established colonoscopy quality metrics (adenoma detection rate [ADR] and withdrawal time [WT]). METHODS: We conducted a prospective observational study to assess polypectomy competency amongst 13 high-volume screening colonoscopists at an academic medical center...

INTRODUCTION: Two second-generation, flexible EUS fine-needle biopsy (FNB) needles have recently been marketed in the United States. Thus far, there have been no comparative studies of the diagnostic yield of these needles. The aim of this study was to compare the diagnostic yield achieved with FNB using one needle during one time period and the other needle during a second time period. METHODS: Consecutive patients with solid lesions undergoing EUS-FNB using one of two 22-gauge FNB needles (Franseen needle or fork-tip) at 2 different time intervals were included...

BACKGROUND: ERCP with self-expandable metallic stent (SEMS) placement provides reliable and durable relief of malignant biliary obstruction. Our objective was to compare efficacy and adverse outcomes between uncovered SEMSs (USEMSs) and covered SEMSs (CSEMSs). METHODS: A retrospective cohort study was performed of all consecutive patients who underwent ERCP with SEMS placement for the management of a malignant bile duct stricture. Comparative analyses on clinical success, patency duration, stent dysfunction and adverse outcomes were performed...

BACKGROUND AND AIMS: Endoscopic transluminal drainage of symptomatic walled-off necrosis (WON) is a good management option, although the optimal choice of drainage site stent is unclear. We performed a systematic review and meta-analysis to compare metal stents (MSs) and plastic stents (PSs) in terms of WON resolution, likelihood of resolution after one procedure, and adverse events. METHODS: An expert librarian queried several databases to identify studies that assessed WON management, and selection was according to a priori criteria...

BACKGROUND: Bile duct stones >1 cm have a decreased incidence of successful endoscopic extraction and often require lithotripsy. Although prior guidelines suggested mechanical lithotripsy for large CBD stones, current guidelines suggest cholangioscopy-guided lithotripsy as an adjunct with or without balloon dilation or mechanical lithotripsy. However, no randomized trials have assessed the utility of this practice. METHODS: Patients with bile duct stones >1 cm in diameter were randomized in a 2:1 ratio to cholangioscopy-guided laser lithotripsy versus conventional therapy only...

BACKGROUND & AIMS: Patients who receive a colonoscopy from a physician with a low adenoma detection rate are at higher risk of subsequent colorectal cancer. It is unclear what drives the variation across physicians in adenoma detection rate. We describe physician characteristics associated with higher ADR. METHODS: In this retrospective cohort study, a natural language processing system was used to analyze all outpatient colonoscopy examinations and their associated pathology reports from October 2013 to September 2015 for adults 40 and older across physicians from four diverse health systems...

BACKGROUND AND AIMS: Colonoscopy performance is typically assessed by a supervisor in the clinical setting. There are limitations of this approach, however, as it allows for rater bias and increases supervisor workload demand during the procedure. Video-based assessment of recorded procedures has been proposed as a complementary means by which to assess colonoscopy performance. This study sought to investigate the reliability, validity and feasibility of video-based assessments of competence in performing colonoscopy, compared with live assessment...

BACKGROUND AND AIMS: Unplanned hospital visits within 7 days of colonoscopy was recently proposed as a quality measure. It is unknown if patient, procedure, or endoscopist characteristics predict post-colonoscopy emergency department (ED) visits. Our aim was to determine the incidence and relatedness of ED visits within 7 days of colonoscopy, and to identify predictors of post-colonoscopy ED use. METHODS: In this retrospective, single-center, cohort study, we evaluated outpatient colonoscopies performed at a tertiary academic medical center or affiliated facility between January 2008 and September 2013...

BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) is a novel, incisionless technique for gastric volume reduction to promote weight loss. Our aim was to describe the learning curve for performing ESG using a prospective case series. METHODS: Using a prospective case series design, we analyzed the first 128 consecutive patients at a tertiary-care academic medical center who underwent ESG performed by a single operator from August 2013 to December 2016. Efficiency (refining performance to decrease procedure time) and mastery (absence of outliers) for performing the ESG was evaluated by using a penalized basis-spline regression and cumulative sum (CUSUM) analysis...

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) for extensive esophageal carcinomas may cause severe stenosis requiring endoscopic balloon dilations (EBD). A standard preventing method has not been established. We propose the esophageal triamcinolone acetonide (TA)-filling method as a novel local-steroid administration procedure. METHODS: We enrolled 22 consecutive patients with early esophageal cancer who were treated using either subcircumferential or circumferential ESD (15 and 7 procedures, respectively) in this case series...
