The Benefits of R Anastomotic Technique for Billroth-Ⅱ Reconstruction With Braun Anastomosis After Totally Laparoscopic Distal Gastrectomy

Study Overview
=================
Brief Summary
-----------------
This study proposes a novel, straightforward, and viable technique for performing posterior gastrojejunostomy anastomosis during totally laparoscopic Billroth-II reconstruction with Braun anastomosis (named R anastomosis). This study prospectively evaluated clinical and pathological data from patients who underwent totally laparoscopic distal gastrectomy with R anastomosis at Northern Jiangsu People's Hospital, China, in order to investigate the feasibility and functional outcomes of R anastomosis for B-II-B anastomosis.

Detailed Description
-----------------
Paients were recruited who were confirmed to have malignant tumors in the gastric antrum or body through endoscopic and pathological examinations, and multi-slice spiral CT scans revealed no distant metastasis. All case underwent totally laparoscopic distal gastrectomy with R anastomosis. Prospectively examined the intraoperative data, including operation time, time for R anastomosis, blood loss; Postoperative data including pathological data, duration of gastric tube placement, time to initiate liquid diet, the length of hospital stay; other functional outcomes and short-term postoperative complication data, graded according to the Clavien-Dindo complication classification system
