TTo explore the safety and feasibility of two types of endovascular digestive tract reconstruction during complete laparoscopic right hemicolonectomy.

Data of 59 patients with right colon cancer from June 2021 to June 2023 were retrospectively analyzed. They were divided into two groups according to different ways of digestive tract reconstruction. A total of 31 patients underwent retroperistaltic "T" anastomosis in digestive tract reconstruction and were set as observation group. 28 patients underwent paracalistaltic overlapping triangular anastomosis in digestive tract reconstruction and were set as control group. SPSS 22.0 software analyzed the data statistically. Perioperative indicators and serum inflammatory factors were expressed as (), and independent sample t test was performed. The statistical data of postoperative complications were analyzed by χ² test or Fisher exact probability method. P<0.05 was considered statistically significant..

All 59 patients successfully completed complete laparoscopic resection of right colon cancer without conversion to laparotomy. The operation time, intraoperative blood loss, anastomosis time, first time to get out of bed after operation and first exhaust time in observation group were better than those in control group, with statistical significance (P<0.05). The levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ) and C-reactive protein (CRP) in 3 days after surgery were increased in both groups, but the observation group was lower than the control group (P<0.05). The incidence of complications in observation group was lower than that in control group (9.6% vs. 17.9%), but the difference was not statistically significant (P>0.05).

In the complete laparoscopic resection of right half colon cancer, the antiperistaltic “T” anastomosis method can significantly shorten the time of digestive tract reconstruction and surgery, and reduce the postoperative inflammatory stress level of the body, which is conducive to postoperative recovery of patients, and is safe and feasible, worthy of further clinical promotion and application.
