To investigate the clinical effect of laparoscopic assisted radical gastrectomy for distal gastric cancer with Uncut Roux-EN-Y anastomosis and modified Uncut Roux-en-Y anastomosis.

The data of 92 patients who received laparoscopic-assisted radical resection of distal gastric cancer from January 2017 to June 2019 were retrospectively analyzed.According to different anastomosis procedures, the patients were divided into two groups, among which 44 cases of Uncut roux-en-y anastomosis were classified as U-ry group. Forty-eight cases of modified Uncut roux-en-y anastomosis were divided into the improved group. Statistical software SPSS 21.00 was used for data analysis. Perioperative indicators such as measurement data using (±s) said, independent t test; The incidence of complications was compared by χ² test. P<0.05 was considered statistically significant.

The duration of operation, first ventilation and hospital stay in the modified group were less than those in the U-RY group (P<0.05). The total incidence of postoperative complications in the improved group was 14.6% (7/48) less than that in the U-RY group, 29.5% (13/44). After 1 year of postoperative follow-up, 9.1% of patients in the U-RY group had closed point recanalization, while no closed point recanalization occurred in the improved group (0%), and there was no statistically significant difference between the two groups (P>0.05).

Laparoscopic assisted radical resection of distal gastric cancer with improved Uncut Roux-en-Y anastomosis is safe and feasible. Compared with traditional U-RY anastomosis, the anastomosis results in faster postoperative recovery, which can reduce the incidence of closed mouth recanalization to a certain extent, and can be popularized in clinical use.
