Previous studies have shown that the mucosa and villi of the left intestinal segment will atrophy after intestinal bypass, the absorption capacity will decrease, and the rhythmic contraction will disappear. Some studies have shown that irrigation through the anorectal cavity may help prevent and treat colorectal anastomotic fistulas and improve the postoperative life of patients. Based on this, it is hypothesized that the stimulation of stomal exudate anal reinfusion to the empty intestinal segment through the anus may help to promote the recovery of intestinal function and intestinal flora disturbance after stoma retraction.~In response to this hypothesis, in this study, we intend to carry out a prospective and observational study on patients with stoma resection, aiming to investigate whether the stimulation of stoma discharge and anal reinfusion of stoma drainage through the anus before resection has any effect on the anus. It is beneficial to the recovery of intestinal function, reducing the occurrence of complications and improving the imbalance of intestinal flora, providing high-level clinical evidence.
To analyze the occurrence of defecation complications, rectal function, and quality of life indicators after sphincter-preserving surgery for middle and low rectal cancer, the stoma exudate was collected before the stoma was restored, and the defecation complications, rectal function and quality of life indicators were evaluated. The effect of anal reinfusion of stoma discharge on the recovery of intestinal function in patients.
