Peroral endoscopic myotomy for patients with achalasia with previous Heller myotomy: a systematic review and meta-analysis

Volume 93, ISSUE 1, P47-56.e5, January 01, 2021
Heller myotomy (HM) is considered the standard surgical treatment for patients with achalasia. However, approximately 10% to 20% of patients with achalasia have persistent or recurrent symptoms after HM that require further therapy. Several studies have reported the outcomes of peroral endoscopic myotomy (POEM) in these patients. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of POEM in patients with achalasia with previous HM.

Volume 93, ISSUE 1, P68-76.e2, January 01, 2021
Colonoscopy is the preferred modality for colorectal cancer screening because it has both diagnostic and therapeutic capabilities. Current consensus states that colonoscopy should be performed with initial rapid passage of the instrument to the cecum, followed by thorough evaluation for and removal of all polyps during a deliberate slow withdrawal. Reports have suggested that polyps that are seen but not removed during insertion are sometimes quite difficult to find during withdrawal.

One-fourth of colorectal neoplasia are missed at screening colonoscopy, representing the main cause of interval colorectal cancer. Deep learning systems with real-time computer-aided polyp detection (CADe) showed high accuracy in artificial settings, and preliminary randomized controlled trials (RCTs) reported favorable outcomes in the clinical setting. The aim of this meta-analysis was to summarize available RCTs on the performance of CADe systems in colorectal neoplasia detection.

The endoscopic evaluation of narrow-band imaging (NBI) zoom imagery in Barrett’s esophagus (BE) is associated with suboptimal diagnostic accuracy and poor interobserver agreement. Computer-aided diagnosis (CAD) systems may assist endoscopists in the characterization of Barrett’s mucosa. Our aim was to demonstrate the feasibility of a deep-learning CAD system for tissue characterization of NBI zoom imagery in BE.

It is unclear whether the common practice of postoperative day (POD) 1 esophagram impacts clinical care or reliably identifies significant adverse events (AEs) related to peroral endoscopic myotomy (POEM). Therefore, we aimed to correlate the most clinically relevant esophagram findings with postoperative outcomes after POEM.

Laparoscopic sleeve gastrectomy (LSG) facilitates significant and durable weight loss; however, weight recidivism and need for revisional surgery occur in a subset of patients. Reduction of a dilated LSG using the revisional endoscopic sleeve gastroplasty (R-ESG) approach is an appealing and minimally invasive alternative to surgical revision that is congruent with obesity as a chronic relapsing disease model. In this study, we examine the safety and efficacy of the technique in a large multicenter international cohort.

EUS-guided FNA primarily provides cytologic samples. EUS-guided fine-needle biopsy (FNB) with needles that provide histologic specimens may enhance diagnostic yield and facilitate accessory tissue staining. Several different needle designs are currently available and design superiority is unknown. We designed a randomized controlled trial to compare 2 commonly used EUS-FNB needles in their ability to provide histologic tissue samples (primary endpoint) and to reach an accurate diagnosis (secondary endpoint).

Volume 93, ISSUE 1, P154-162.e5, January 01, 2021
Most patients with pancreatic cancer are diagnosed at a late stage and are not candidates for surgical resection. Many have jaundice requiring biliary drainage, which can be accomplished using ERCP or percutaneous transhepatic biliary drainage (PTBD). To date, no studies have evaluated the impact of ERCP or PTBD on survival among patients with unresectable pancreatic cancer. The aims of our study were to compare overall survival between patients with unresectable pancreatic cancer receiving ERCP with those receiving PTBD, to compare overall survival between patients who received a biliary intervention (ERCP or PTBD) versus those who received no biliary intervention, and to compare secondary outcomes, such as length of hospital stay and costs, between ERCP and PTBD.
ERCP is superior to percutaneous transhepatic biliary drainage in unresectable pancreatic head cancer, but should everyone be decompressed?

Volume 93, ISSUE 1, P187-192, January 01, 2021
Capsule endoscopy (CE) is an important modality for diagnosis and follow-up of Crohn's disease (CD). The severity of ulcers at endoscopy is significant for predicting the course of CD. Deep learning has been proven accurate in detecting ulcers on CE. However, endoscopic classification of ulcers by deep learning has not been attempted. The aim of our study was to develop a deep learning algorithm for automated grading of CD ulcers on CE.
