Purpose A protective loop ileostomy is the most useful method to reduce sequelae in the event of an anastomotic leakage (AL) after rectal cancer surgery. However, it requires an additional stoma reversal surgery with its own potential complications. Postoperative ileus (POI) remains the most common complication after ileostomy reversal, which leads to an increase in morbidity, length of hospital stay (LOS) and overall healthcare costs. Several retrospective studies carried out in this feld have concluded that there are insufcient evidence-based recommendations about the routine application of preoperative bowel stimulation in clinical practice. Here we discuss whether stimulation of the eferent limb before ileostomy reversal might reduce POI and improve postoperative outcomes. Methods This is a multicentre randomised controlled trial to determine whether mechanical stimulation of the eferent limb during the 2 weeks before the ileostomy reversal would help to reduce the development of POI after surgery. This study was registered on (NCT05302557). Stimulation will consist of infusing a solution of 500 ml of saline chloride solution mixed with a thickening agent (Resource©, Nestlé Health Science; 6.4 g sachet) into the distal limb of the ileostomy loop. This will be performed within the 2 weeks before ileostomy reversal, in an outpatient clinic under the supervision of a trained stoma nurse. Conclusion The results of this study could provide some insights into the preoperative management of these patients.
