title: Totally laparoscopic total gastrectomy using the overlap method; early outcomes of 50 consecutive cases.
abstract: Construction of an esophagojejunostomy is still a challenging procedure in totally laparoscopic total gastrectomy (TLTG), and there is no standard anastomosing method. The aims of this study were to describe our TLTG with the overlap method using a linear stapler and report surgical outcomes.
  
  
  
  From January 2015 to April 2016, 50 patients underwent TLTG using the overlap method for gastric cancer. The procedures were performed by a single surgeon, and the patients' medical records were reviewed. Their clinicopathologic characteristics, operation time, date of flatus, hospital stay, morbidity, and mortality were analyzed.
  
  
  
  The median age and body mass index were 56 years and 23.5, respectively. Stage 1A tumors were the most common. Mean operating time was 144.6 min, and no cases required changing to open laparotomy during surgery. On average, flatus occurred 3.5 days after surgery, and patients were discharged 6.8 days after surgery. No patient experienced anastomosis leakage, stricture, duodenal stump leakage, luminal bleeding, pancreatic fistula, or wound problems. There were two cases of intra-abdominal bleeding that required additional surgery. Intra-abdominal fluid collection and mechanical ileus occurred in two patients, respectively, and were successfully managed with conservative treatment.
  
  
  
  We reported favorable surgical outcomes of TLTG using the overlap method. It is a feasible and safe option for treatment of gastric cancer.
