[The research on the application of uncut Roux-en-Y esophagojejunostomy in the digestive reconstruction after totally laparoscopic total gastrectomy].

Objective: To evaluate the safety and flexibility of uncut Roux-en-Y esophagojejunostomy in totally laparoscopic total gastrectomy (TLTG). Methods: Between July 2016 to November 2016, 15 patients received totally laparoscopic total gastrectomy plus uncut Roux-en-Y esophagojejunostomy in the Sir Run Run Shaw hospital. Clinical data of those patients, including operative indexes, post-operative indexes and fellow-up data, were analyzed respectively. Results: A total of 15 patients were enrolled in this study, ten were corpus carcinoma and five were esophagogastric junction carcinoma. The total operative time and anastomosis time was (25.0±4.3) min and (25.0±4.3) min, the blood loss during operation was (133.3±121.2) ml. All the operations were performed successfully, and no one was transferred to open surgery. All the patients were encouraged to off-bed activity at first day after surgery. The first time to flatus, the first time to liquid food intake and the length of stay in hospital were (4.1±0.8) days, (5.1±0.9) days and (9.3±1.6) days, respectively. The pathological staging of these patients was stage Ⅰb in 1 case, stage Ⅱa in 3 cases, stageⅡb in 2 cases, stage Ⅲb in 3 cases, stage Ⅲc in 6 cases. The lymph node harvest was (36.0±12.3). Cutting margins in all patients were negative. Pulmonary infection occurred in one patient postoperatively and recovered after antibiotic treatment. No death and severe complication was found. Liver metastasis occurred in one patient eight months after operation. One patient was found recurrence in anastomotic site. No Roux-en-Y stasis syndrome was found. Conclusions: Uncut Roux-en-Y esophagojejunostomy in TLTG is safe and flexible.
