Non-Exposure Endoscopic-Laparoscopic Cooperative Surgery for Stomach Tumors: First Experience from the Czech Republic: Jan Hajer, Lukáš Havlůj, Adam Whitley, Robert Gürlich; Clin Endosc 2018;51(2):167-173. Published online January 4, 2018; DOI: https://doi.org/10.5946/ce.2017.076

Background
/Aims: The aim of this study was to investigate the use of non-exposure endoscopic wall-inversion surgery (NEWS) and the combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique (CLEAN-NET) in gastric tumors.
Methods
We reviewed all cases of NEWS and CLEAN-NET performed in the department of surgery of the Royal Vinohrady Teaching Hospital.
Results
Our department performed 12 gastric tumor resections (NEWS, n=10 and CLEAN-NET, n=2) between March 2016 and February 2017. The cases chosen for these resections included predominantly submucosal tumors with no signs of dissemination or local invasion and early gastric carcinomas (T1_SM1 and T1_M), where tumor location made it impossible to use endoscopic submucosal dissection. R0 resection margins were confirmed in all the cases.
Conclusions
NEWS and CLEAN-NET allow en bloc non-exposed full-thickness gastric wall resection in a way that uses a “close first, cut later” approach to prevent seeding of the peritoneal cavity with tumor cells. These mini-invasive techniques combine laparoscopic and endoscopic techniques, and preserve the full function of the stomach.
