The Protective Role of GABA Stimulation Before Ileostomy Closure

Phase 3

Not yet recruiting

• Conditions: Ileostomy; Complications
• Interventions: Dietary Supplement: preoperative stimulation of the efferent loop with GABA before ileostomy closure surgery; Dietary Supplement: preoperative stimulation of the efferent loop with only physiological saline

• Registration Number: NCT05905393
• Lead Sponsor: Qilu Hospital of Shandong University

Brief 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.

Arm && Interventions

Group	Intervention	Description
preoperative stimulation of the efferent loop with GABA before ileostomy closure surgery	preoperative stimulation of the efferent loop with GABA before ileostomy closure surgery	Preoperative stimulation of the distal limb of the ileostomy loop with GABA was performed during the 5 days prior to surgery every day. During the process and after it, the patient himself registers the appearance of symptoms after each stimulation session: abdominal pain, emission of gas and stool. Sterile 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. Each preparation was made under sterile conditions and maintaining the cold chain.
control group was stimulated without giving any substance	preoperative stimulation of the efferent loop with only physiological saline	Control group was stimulated without giving any substance. During the process and after it, the patient himself registers the appearance of symptoms after each stimulation session: abdominal pain, emission of gas and stool. After 5 stimulation sessions, reconstructive surgery was performed within the following 24 h.
