To analyze the effect of modified double channel anastomosis (DTR) in total laparoscopic proximal gastrectomy.

Data of 96 patients with proximal gastric cancer from May 2018 to May 2022 were retrospectively analyzed and divided into two groups according to different operation methods, with 48 patients in each group. Control group underwent laparoscopic total gastrectomy +Roux-en-Y digestive tract reconstruction, observation group underwent complete laparoscopic proximal gastrectomy + modified DTR. SPSS 26.0 software was used to analyze the data. Perioperative indexes, nutritional indexes and other measurement data were expressed as (), and independent sample t test was used. The statistical data of postoperative complications were analyzed by χ² test. P < 0.05 was considered statistically significant.

There was no significant difference in operation time, blood loss, number of lymph node dissection, time to get out of bed, time to exhaust gas and time to stay in hospital between the two groups (P > 0.05). The levels of hemoglobin, albumin and total protein in observation group were higher than those in control group 3 months after operation (P < 0.05); The total incidence of postoperative complications in the observation group was significantly lower than that in the control group (10.4% vs. 27.1%, P<0.05).

The modified DTR has better safety and feasibility in total laparoscopic proximal gastrectomy. Compared with total gastrectomy Roux-en-Y digestive tract reconstruction, it can help improve the nutritional status of patients and reduce postoperative complications.
