Technology
This work describes the use of an over-the-scope-clip system (OTSC), made of super-elastic Nitinol and a specially designed tissue-approximating double jaw endoscopic grasper for gastric closure. The OTSC is a clipping system mounted at the tip of the endoscope and is used for the treatment of gastrointestinal bleeding or gastrointestinal organ perforations. An enlarged version of the OTSC is now under investigation for NOTES.

This article aims to answer a highly debated question: can gastroenterologists easily learn the procedure-related surgical knowledge or is it is easier to teach surgeons to handle the conventional flexible endoscopes.

Experimental work
Perioperative hematologic parameters during NOTES was compared with those during standard laparoscopy in 12 swines randomized to transgastric peritoneoscopy with air or diagnostic laparoscopy using carbon dioxide.

Serum interleukins and peritoneal cellular response have been utilized to support the immunologic difference between open and laparoscopic surgery. This study explores the difference between cytokine levels during NOTES and laparoscopic peritoneoscopy.

The aim of this pilot study was to compare adhesion formation after performance and subsequent repair of colonic perforation via transgastric, laparoscopic, or open surgical techniques and to test the feasibility and outcome of transgastric management of bowel perforation in a prepared model.

Human Applications
This paper describes an innovative technique in which the entire colon is extracted transvaginally to avoid any abdominal extraction incision in a female patient with hereditary nonpolyposis colon cancer who required total colectomy and hysterectomy.

This paper reports a transumbilical approach for the endoscopic appendectomy in 8 out of 12 patients in which the procedure was attempted.

Standard management of walled-off pancreatic necrosis (WOPN), a known complication of acute and chronic pancreatitis, is open surgical debridement and drainage, a procedure associated with substantial morbidity and mortality. This study presents a novel minimally invasive approach to adequately remove and drain pancreatic necrosis. In 5 of 6 cases of WOPN treated with minimally invasive laparoendoscopic surgery, conventional surgery was avoided over a median follow-up of 14 months.

Access/Closure
This video describes a rendez-vous procedure using simultaneous transgastric and transcolonic approaches to perform a small bowel resection. This is done in order to provide greater range of motion and freedom of movement.

This article presents a single-port laparoscopic colorectal surgery using a Uni-X [TM] Single Port Access Laparoscopic System with a multi-channel cannula and specially designed curved laparoscopic instrumentation. The abdomen was approached through a 3.5 cm incision via the umbilicus and a single-port access device was utilized to perform a right hemicolectomy on a patient with an unresectable cecal polyp and a body mass index of 35. Ligation of the ileocolic artery was done with a LigaSure device and was followed by colonic mobilization, extraction and extracorporeal ileocolic anastomosis.
