Abstract:
Objective:To investigate the effects of two anastomosis methods on perioperative and pathological outcomes during totally laparoscopic right hemicolectomy (TLRH).Methods:In a national multicenter snapshot study, 1,854 patients who underwent laparoscopic right hemicolectomy were enrolled from 52 tertiary hospitals across China. The post-hoc analysis based on this study compared the data of 303 patients who underwent TLRH. Patients were divided into the antiperistaltic group (33 cases) and the isoperistaltic group (270 cases) according to type of anastomosis. Due to the significant difference in sample size between the two groups, propensity score matching (PSM) was performed to eliminate the influence of baseline characteristic discrepancies. The matching was based on the following known confounding factors: age, gender, body mass index (BMI), history of abdominal surgery, and history of diabetes, with a caliper value of 0.2. Perioperative and pathological outcomes were compared between the two groups.Results:After PSM, 33 patients were included in the antiperistaltic group and 65 patients in the isoperistaltic group. There were no statistically significant differences in baseline data between the two groups (all P>0.05). No significant differences were observed between the two groups in terms of operation time, blood loss, time to first defecation, time to first oral intake, or the incidence and grading of complications either (all P>0.05). However, length of postoperative hospital stay in the isoperistaltic group was significantly shorter than that in the antiperistaltic group, however (7.0 [6.0, 9.0] days vs. 8.0 [7.0, 10.5] days, P=0.049). In terms of pathological outcomes, there were also no statistically significant differences between the two groups in the number of harvested lymph nodes or the number of positive lymph nodes (all P>0.05). Conclusions:The two digestive tract reconstruction modalities, antiperistaltic and isoperistaltic anastomosis, have comparable perioperative safety and efficacy in TLRH. The isoperistaltic group had better outcomes in terms of postoperative hospital stay.
