Clinical Trial Summary

The goal of this clinical trial is to explore whether preoperative stimulation of the distal limb of the ileostomy loop with gamma aminobutyric acid (GABA) could effectively reduce the incidence of complications after ileostomy closure.

Participants will be divided into two groups. One group included patients treated with stimulation of the efferent loop with GABA prior to transit reconstruction surgery; the other control group was stimulated without giving any substance.

Researchers will compare incidence of complications such as postoperative ileus, diarrhea and other parameters such as time to tolerating a diet, start of the passage of flatus, start of the passage of stool, postoperative stay, etc.

Intervention

Dietary Supplement:
• preoperative stimulation of the efferent loop with GABA before ileostomy closure surgery
Foley catheter No.14 Ch connected to an infusion set was introduced through the defunctioned bowel to allow the slow infusion, for 10-20 minutes, of a solution with 3000 mg of GABA diluted in 100 ml of 0.9% physiological saline.
• preoperative stimulation of the efferent loop with only physiological saline
Foley catheter No.14 Ch connected to an infusion set was introduced through the defunctioned bowel to allow the slow infusion, for 10-20 minutes, of 100 ml of 0.9% physiological saline.
