A clinical study of laparoscopic total gastrectomy assisted by small incision and subsequent gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction / 中国医师杂志

ABSTRACT

Objective:To introduce the operation process of laparoscopic total gastrectomy assisted by small incision and gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction, and evaluate its feasibility, safety during perioperative period, and advantages of anastomosis.Methods:A total of 56 patients with gastric cancer who underwent laparoscopic total gastrectomy assisted by small incision and gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction were selected as study subjects from Zhejiang Provincial People′s Hospital between May 2022 and June 2023. Gender, age, body mass index (BMI), tumor location, tumor stage, tumor type and other related indicators were collected. The main parameters during the operation process were collected, including operation time, anastomosis time, intraoperative blood loss, postoperative recovery status, exhaust time, feeding time, complications related to anastomosis, and length of hospital stay. The differences between other digestive tract reconstruction methods such as Overlap method, reverse puncture method, and handmade anastomosis were compared and analyzed.Results:A total of 56 patients with gastric cancer were included in this study. The anastomosis time of the tubular instrument group was (42.3±15.7)min, which was superior to the handmade anastomosis group ( P<0.05). The operation time of the tubular instrument group was (176.3±25.8)min, which was superior to other methods (all P<0.05). The intraoperative blood loss of the tubular instrument group was (75.68±20.34)ml, which was less than other methods (all P<0.05). The exhaust time of the tubular instrument group was (2.6±0.2)d, which was similar to the Overlap method ( P>0.05), but earlier than the handmade anastomosis method and the reverse puncture method (all P<0.05). The incidence of anastomotic leakage in the tubular instrument group was similar to the handmade anastomosis method, the reverse puncture method, and the Overlap method (all P>0.05). There were no significant differences in postoperative hospital stay, incision infection rate, and other complications related to anastomosis between groups (all P>0.05). Conclusions:The tubular instrument anastomosis method has a shorter operation time and a smaller incision compared to traditional laparotomy surgery. It has the advantages of laparoscopic assistance with intuitive and clear visualization during the operation, while also taking into account the convenience and safety of direct visualization under laparoscopy. It is a surgical method worthy of promotion.
