Clinical Scorecard: ILEOSTIM Trial: Protocol for Assessing the Efficacy of Efferent Loop Stimulation Prior to Ileostomy Reversal
At a Glance
Category
Detail
Condition
Postoperative ileus (POI) following ileostomy reversal after low anterior resection for rectal cancer
Key Mechanisms
Preoperative stimulation of the defunctionalized bowel segment to improve absorptive and motor function, reduce microbial dysbiosis and atrophy, thereby potentially reducing POI incidence
Target Population
Adult patients undergoing elective loop ileostomy reversal after low anterior resection for rectal cancer
Care Setting
Multicentre surgical and outpatient clinic settings involving colorectal surgery and stoma care
Key Highlights
Ileostomy reversal carries a high postoperative complication rate (11%-45%), with POI incidence up to 32%.
Preoperative efferent limb stimulation involves daily irrigation with saline and nutritional thickener for 2 weeks before surgery.
Primary outcome is reduction in POI incidence; secondary outcomes include length of stay, morbidity, and functional outcomes including LARS.
Guideline-Based Recommendations
Diagnosis
Use water-soluble enema preoperatively to exclude anastomotic leakage or stenosis before ileostomy reversal.
Management
Randomise patients to receive either preoperative efferent limb stimulation or no stimulation prior to ileostomy reversal.
Perform ileostomy reversal using either stapled or hand-sewn anastomosis as per centre protocol.
Administer antibiotic and antithrombotic prophylaxis according to local hospital policy.
Monitoring & Follow-up
Monitor for POI defined as intolerance to oral intake from postoperative day 3 requiring nasogastric tube or associated symptoms.
Assess postoperative complications using Clavien–Dindo classification.
Evaluate mid-term outcomes including hospital readmission, incisional hernia, and LARS score at 1 and 6 months.
Risks
Potential postoperative complications include anastomotic leakage, surgical site infections, urinary tract infections, pneumonia, acute kidney injury, thromboembolic events, small bowel obstruction, myocardial infarction, stroke, reoperation, and mortality.
Patient & Prescribing Data
Adults undergoing elective loop ileostomy reversal after low anterior resection for rectal cancer
Daily preoperative stimulation of the efferent limb with saline and nutritional thickener for 2 weeks may improve bowel function and reduce POI incidence; supervised by stoma nurse with outpatient support.
Clinical Best Practices
Obtain informed consent detailing study aims, benefits, and risks prior to randomisation.
Standardise preoperative protocols including exclusion of anastomotic complications via imaging.
Provide patient education and nursing support for home-based bowel stimulation.
Use consistent anastomotic technique within centres to reduce variability.
Apply validated scoring systems (Clavien–Dindo, LARS score) for complication and functional outcome assessment.
