Autologous Probiotics in Patients With Defunctioning Ileostomy Following LAR for Rectal Cancer

Rectal cancer patients who received low anterior resection combined with ileostomy may effectively reduce the probability of anastomotic leakage after surgery. However, due to the long-term semi-abandoned state of the distal colon, the probability of bowel dysfunction after ileostomy closure is very high. The incidence of low anterior resection syndrome (LARS) exceeds 70%, which is twice that of those who did not receive a preventive stoma. The main reasons include postoperative anatomical structure alteration, nerve damage, pathological changes of the colorectal mucosa, and gut microbiota variation, etc. The application of probiotics can significantly improve the bowel function of these patients. In this study, in order to enhance the colonization effect of probiotics, autologous probiotics will be applied to treat patients with defunctioning ileostomy. The primary outcome is the occurrence of major LARS after 6 months of the treatment.
