Objective To investigate the application value of modified closure of overlap anastomotic common opening in total laparoscopic radical gastrectomy.

Methods The retrospec-tive and descriptive study was conducted. The clinicopathological data of 39 patients with gastric cancer who underwent total laparoscopic radical gastrectomy in Shanxi Hospital of Cancer Hospital, Chinese Academy of Medical Sciences from January 2023 to January 2024 were collected. There were 27 males and 12 females, aged (61±9)years. All patients underwent total laparoscopic radical gastrectomy for gastric cancer, with gastrointestinal reconstruction using overlap anastomosis and a modified closure of overlap anastomotic common opening. Measurement data with normal distribution were represented as Mean±SD, and count data were expressed as absolute numbers.

Results (1) Intraoperative and postoperative conditions. All 39 patients underwent total laparoscopic radical gastrectomy for gastric cancer, with gastrointestinal reconstruction using overlap anastomosis and a modified closure of overlap anastomotic common opening successfully, without conversion to open surgery or thoracotomy. The operation time of 39 patient was (210±52)minutes, with the volume of intraoperative blood loss of (132±55)mL, number of lymph node dissected of 23±11. The time to postoperative first flatus of 39 patients was (3.3±0.3)days, with time to postoperative liquid food intake of (4.4±0.6)days, time to postoperative semi‑liquid food intake of (5.2±0.4)days, and duration of postoperative hospital stay of (9.5±3.1)days. (2) Complications. Seven of the 39 patients experienced perioperative complications, including 5 cases with complication classified as Clavien⁃Dindo grade Ⅱ, and 2 cases with complication classified as Clavien‑Dindo grade Ⅲ. After conservative treatment, all patients with complications improved and were discharged. (3) Follow‑up. Results of upper gastrointestinal imaging of the 39 patients showed no anastomotic leakage, and all patients were followed up at 1, 3, and 6 months after surgery. There was no other complications, tumor recurrence and metastasis, or mortality during the follow‑up period.

Conclusion The modified closure of overlap anastomotic common opening in total laparoscopic radical gastrectomy has good safety and short‑term efficacy.
