Abstract:Objective To investigate the effect of stoma translocation via ipsilateral rectus abdominis after laparoscopic parastomal hernia repair on defecation function. Methods A retrospective analysis was performed on the clinical data of 62 patients with parastomal hernia admitted to the General Surgery Department of the Fourth Affiliated Hospital of Harbin Medical University from September 2016 to September 2019. There were 32 patients undergoing stoma translocation via ipsilateral rectus abdominis (stoma transposition group) and 30 patients undergoing stoma in-situ (stoma in-situ group). The intraoperative conditions, hospitalization indexes, postoperative complications and postoperative defecation function were compared between two groups. Results There were no significant differences in operation time, stoma time, intraoperative blood loss, postoperative hospital stay and hospitalization expenses between two groups ( P >0.05). The incidence of infection in stoma translocation group was significantly lower than that in stoma in-situ group (3.13% vs 23.33%, χ 2=3.972, P =0.046). One year after operation, the defecation control ability were evaluated and grouped into excellent (15 cases), good (6 cases), fair (5 cases), poor (6 cases) in stoma translocation group and excellent(4 cases), good(11 cases), fair (8 cases) and poor(7 cases) in stoma in-situ group,respectively. The ability of defecation control in stoma translocation group was better than that in stoma in-situ group ( Z =2.208， P =0.043）. Conclusion The stoma transposition via ipsilateral rectus abdominis after laparoscopic parastomal hernia can effectively reduce complications, postoperative defecation control is better, and the clinical effect is satisfactory.
