Full-thickness resection techniques are of growing interest in the field of endoscopic removal of tumors or their precursors in the digestive tract. A new dedicated full-thickness resection device has been developed based on the combination of the OTSC clip, an enlarged resection cap and an integrated snare. The device prototype allows combined resection of all gastrointestinal organ wall layers in one maneuver, up to a size of 3 x 3 cm. The device has been pre-clinically tested to demonstrate feasibility of full-thickness resection in the colon. Two clinical cases have been performed successfully to date.

Peroral flexible endoscopy is a minimally invasive technique that enables the local resection of gastric subepithelial tumors (SETs) with malignant potential. Resection techniques are mainly chosen on the basis of the lesion size. Minute SETs less than 1 cm should be managed through a watch and wait strategy, with the exception of histologically diagnosed superficial lesions, which require endoscopic mucosal resection or endoscopic submucosal dissection.

However, except for select diseases such as Hirschsprung's Disease or Achalasia that show a significant loss of all neurons or a subset of neurons, our understanding of human ENS histopathology is extremely limited. Recent endoscopic advances allow biopsying patient's full thickness gut tissues, which makes capturing ENS tissues simpler than biopsying other neuronal tissues, such as the brain.

Background: Endoscopic resection of giant gastric leiomyomas, particularly in the fundus and cardia regions, is infrequently documented and presents a significant challenge for endoscopic surgery.
Case Summary: Herein, a case of a 59-year-old woman with a giant gastric leiomyoma was reported. The patient presented to the department of hepatological surgery with a complaint of right upper abdominal pain for one month and worsening for one week.

Introduction: Roux-en-Y gastric bypass (RYGB) reversal might be necessary to alleviate refractory surgical or nutritional complications, such as postprandial hypoglycemia, malnutrition, marginal ulceration, malabsorption, chronic diarrhea, nausea and vomiting, gastro-esophageal reflux disease, chronic pain, or excessive weight loss. The surgical technique of RYGB reversal is not standardized; potential strategies include the following: (1) gastro-gastrostomy: hand-sewn technique, linear stapler, circular stapler; (2) handling of the Roux limb: reconnection or resection (if remaining intestinal length ≥ 4 m).
Case Presentation: We demonstrate the surgical technique of a laparoscopic reversal of RYGB with hand-sewn gastro-gastrostomy and resection of the alimentary limb with the aim of improving the patient's quality of life.
