About

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.

Full description

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.

60 participants in 2 patient groups

Experimental group

Experimental group

Description:

The stoma drainage fluid was reinfused once a week for 2 months after radical rectal surgery. For each reinfusion, eat liquid food the day before, collect 400-600mL of stoma discharge on the same day (if the stoma fluid is too small, it can be mixed with warm water), and use an enema bag to reinfuse from the patient's anus. Generally, the flow rate is controlled at about 100mL/min.

Treatment:

Procedure: stoma drainage reinfusion

Conventional group

Sham Comparator group

Description:

The conventional group received no additional intervention.

Treatment:

Procedure: Standard of Care - No Return of Stoma Drain
