Abstract: Objective  To introduce the robotic-assisted left hemicolectomy and Soave procedure and its clinical outcome for Hirschsprung’s allied disease.Methods From June 2015 to November 2022,19 cases diagnosed with Hirschsprung’s allied disease underwent left colectomy and Soave pull-through by using the da Vinci surgical system,and the clinical data of 19 children were summarized and analyzed.A four trocar technique was used.The left colon was firstly mobilized by laparoscopy from splenic flexure of colon to the level of peritoneal reflection,then the rectum was mobilized by Robotic system to the level of dentate line.A circumferential incision was made in the mucosa at 0.5 cm proximal to the dentate line.The upward submucosal dissection was carried out for approximately 1-2cm.The left colon was pulled through the anal canal and resected.The coloanal anastomosis was fashioned manually 0.5cm above the dentate line.21 cases underwent conventional laparoscopic-assisted Soave surgery were used as control group.Results All patients were successfully operated.Compared with conventional laparoscopic-assisted Soave surgery,the operation time was significantly prolonged (P<0.01),the intraoperative blood loss was significantly reduced (P<0.01),and the overall postoperative complication rate was significantly reduced (11% VS.43%,P<0.05).There were no serious complications such as major bleeding and death.Conclusion Robotic-assisted left hemicolectomy and Soave procedure are safe and feasible in the treatment of Hirschsprung’s allied disease,with few postoperative complications and satisfactory clinical outcome.
