Extended Resection for Rectal Cancer With Neoadjuvant Radiotherapy

During the operation, the splenic flexure of the colon was first freed, and then the physiological adhesion site of the sigmoid colon was located. Routine laparoscopic or open rectal cancer radical resection (D3 dissection + high ligation) was performed. The proximal end of the colon is disconnected 10-15cm away from the physiological adhesion site of the sigmoid colon. The anastomosis method was manual anastomosis or stapler anastomosis, and a prophylactic ileal loop ostomy was routinely performed.
