Application value of manual anastomosis of gastroduodenum in totally laparoscopic distal gastrectomy / 中华消化外科杂志

ABSTRACT

Objective:To investigate the application value of manual anastomosis of gastro-duodenum in totally laparoscopic distal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 55 patients with gastric cancer who underwent totally laparoscopic distal gastrectomy combined with gastrointestinal anastomosis in the Tianjin Medical University Cancer Institute & Hospital from January 2020 to October 2022 were collected. There were 34 males and 21 females, aged 61(range, 29?75)years. Of 55 patients, 25 patients undergoing manual anastomosis of gastroduodenum were divided into the manual anastomosis group, 30 patients undergoing modified Delta anastomosis of gastroduodenum were divided into the modified Delta anastomosis group. Observation indicators (1) surgical situations; (2) postoperative complications. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using chi-square test or Fisher exact probility. Results:(1) Surgical situations. All 55 patients underwent surgery successfully, without conversion to laparotomy. The distance from the superior margin of tumor to the upper margin, anastomosis time, number of bookings used were (48±4)mm, (22.6±2.3)minutes, 3.2±0.5 in the manual anastomosis group, versus (41±4)mm, (14.0±1.4)minutes, 5.2±0.4 in the modified Delta anastomosis group, showing significant differences in the above indicators between the two groups ( t=5.04, 16.38, ?17.13, P<0.05). The location of tumor (antrum, gastric angle) was 18, 7 in the manual anastomosis group, versus 29, 1 in the modified Delta anastomosis group, showing a significant difference between the two groups ( P<0.05). (2) Postoperative complications. There was no patient undergoing anastomotic fistula in both of manual anastomosis group and modified Delta anastomosis group, and there was 1 patient undergoing anastomotic stenosis in the modified Delta anastomosis group. Conclusion:Compared with modi-fied Delta anastomosis of gastroduodenum,totally laparoscopic distal gastrectomy with manual anas-tomosis of gastroduodenum can remove more gastric tissue, and decrease the number of bookings used.
