Summary

Preoperative neoadjuvant therapy has become the guideline-recommended standard treatment for patients with locally advanced or mid-to-low rectal cancer with suspected regional lymph node metastasis. However, preoperative neoadjuvant radiotherapy caused radiation damage to the pelvic bowel, resulting in varying degrees of edema, vascular stiffness, and insufficient blood supply. According to the traditional rectal cancer surgery, the proximal bowel resection only needs to be more than 10cm above the upper edge of the tumor. However, this range of resection cannot remove all the damaged proximal bowel, and using the damaged proximal bowel for anastomosis may lead to the risk of anastomotic-related complications (including anastomotic leakage, anastomotic stenosis, and anastomotic proximal bowel stiffness, etc.) also increased. Therefore, extended resection of the proximal bowel with splenic flexure mobilization and using healthy proximal bowel for anastomosis may help reduce the incidence of complications related to rectal anastomosis after neoadjuvant therapy.

Conditions

  • the Incidence of Complications Related to Rectal Anastomosis After Neoadjuvant Therapy

Interventions

PROCEDURE

extended resection with splenic flexure mobilization

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.
