Background: Endoscopic submucosal tunneling has evolved to allow endoscopic resection of subepithelial tumors of gastrointestinal tract without full-thickness perforation. This study aimed to investigate safety and efficacy of submucosal tunnel resection for these tumors.
Method: Patients with subepithelial tumors (SET) located in esophagus, gastric cardia, lesser curvature, and antrum were recruited.

Purpose of Review The study aimed to discuss novel endoscopic approaches to resection of submucosal lesions. Recent Findings Endoscopic resection by excavation, full-thickness resection, and submucosal tunneling are by now well-documented techniques for submucosal tumor resection. Combined approaches with laparoscopy such as several variations of laparoscopic endoscopic cooperation surgery (LECS) and non-exposed wall-inversion surgery (NEWS) are also possible now.

The aim of the study is to assess if R-LESS is feasible with standard robotic instruments via a single incision and whether the approach could reduce the difficulty of the procedure and confer additional benefits over conventional LESS.
Methods: This was a prospective randomized controlled study investigating the workload performance, efficacy, and risks of performing R-LESS when compared with human LESS (H-LESS) in a survival porcine model for cholecystectomy and gastrojejunostomy.
Background & Aims: In patients with persistent symptoms after Heller myotomy (HM), treatment options include repeat HM, pneumatic dilation, or peroral endoscopic myotomy (POEM). We evaluated the efficacy and safety of POEM in patients with achalasia with prior HM vs without prior HM.
Methods: We conducted a retrospective cohort study of 180 patients with achalasia who underwent POEM at 13 tertiary centers worldwide, from December 2009 through September 2015.
Background And Aims: The recent development of EUS-guided gallbladder drainage (EGBD) with a lumen-apposing stent has made endoscopic assessment and advanced gallbladder interventions via the stent possible. The aim of this study was to assess the feasibility and safety of per-oral cholecystoscopy and the types of gallbladder interventions that can be performed.
Methods: This was a retrospective review conducted in the Prince of Wales Hospital from June 2012 to March 2016.
Background And Aims: Per-oral endoscopic myotomy (POEM) has shown promising safety and efficacy in short-term studies. However, long-term follow-up data are very limited. The aims of this study were to assess (1) clinical outcome of patients with a minimum post-POEM follow-up of 2 years and (2) factors associated with long-term clinical failure after POEM.

Preoperative ultrasonography identified an 8-cm tubular structure at the tender point that was mistaken as appendicitis. Emergency operation finally confirmed a 12-cm giant Meckel's diverticulum with genuine inflammation and imminent perforation.

Endoscopic submucosal dissection (ESD) is gaining popularity over endoscopic mucosal resection for treatment of superficial upper gastrointestinal cancers. It allows a more controlled en-bloc resection of intramucosal neoplasia allowing larger lesion in both stomach and esophagus to be resected. Lower local recurrence rate can be achieved.

Apart from the related esophageal abnormality, another striking feature was noted: free gas under the diaphragm. The patient, however, complained of no other gastrointestinal symptom and showed no sign of peritonism.
