BACKGROUND: Gastroparesis is a debilitating functional disorder of the stomach characterized by delayed gastric emptying absent an obstructive etiology. Surgical or endoscopic disruption of the pylorus has been utilized to treat this disease, but there is little evidence comparing laparoscopic pyloroplasty (LP) with endoscopic per-oral pyloromyotomy (POP). Herein we describe our experience at our institution using a propensity-matched cohort study to compare outcomes between these procedures...

BACKGROUND: Three-dimensional (3D) printing technology has recently been well approved as an emerging technology in various fields of medical education and practice; e.g., there are numerous studies evaluating 3D printouts of solid organs. Complex surgery such as extended mesenterectomy imposes a need to analyze also the accuracy of 3D printouts of more mobile and complex structures like the diversity of vascular arborization within the central mesentery. The objective of this study was to evaluate the linear dimensional anatomy landmark differences of the superior mesenteric artery and vein between (1) 3D virtual models, (2) 3D printouts, and (3) peroperative measurements...

BACKGROUND: Flexible endoscopes ability to manipulate the intestinal environment is limited. As a result, complex endolumenal procedures are often technically demanding and result in long procedure times, impacting institutional resources. Single- and double-balloon add-on endoscopic devices have been employed throughout the GI tract to facilitate tissue control e.g., small bowel enteroscopy, with recent reports suggesting a possible colonic utility for complex procedures e.g., ESD. Our objective was to objectively analyze the efficacy of a new double-balloon device in performing ESD...

BACKGROUND: Emerging evidence has demonstrated that either laparoscopic-assisted gastrectomy (LAG) or robotic-assisted gastrectomy (RAG) could be adopted as standard treatment for early gastric cancer. However, the long-term survival and recurrence rate after LAG or RAG for locally advanced gastric cancer (AGC) has seldom been reported. METHODS: We retrospectively analyzed the data from 339 patients who underwent LAG and 163 patients who underwent RAG from a prospectively established database in the Chinese People's Liberation Army General Hospital...

BACKGROUND: The magnetic sphincter augmentation (MSA) device was initially implanted with minimal hiatal dissection (MHD) at the diaphragmatic hiatus. Due to concern of possible MSA device dysfunction if herniated into an occult or small hiatal hernia, and increased understanding to the role of defective crura in reflux disease, the operative procedure was changed to planned obligatory dissection (OD) of the hiatus at the time of all implantations. METHODS: Between December 2012 and September 2016, 182 patients underwent MSA implant at a single medical center and have complete records available for review through September 2017...

BACKGROUND: Laparoscopic cholecystectomy is the most commonly performed laparoscopic procedure. It is superior in nearly every regard compared to open cholecystectomies. The one significant aspect where the laparoscopic approach is inferior regards the association with bile duct injuries (BDI). The BDI rate with laparoscopic cholecystectomy is approximately 0.5%; nearly triple the rate compared to the open approach. We propose that 0.5% BDI rate with the laparoscopic approach is no longer accurate...
