[Usefulness of plug test for the intraoperative staging of rectal mucosal prolapse].
Rectal mucosal prolapse is characterised by protrusion of the rectal mucosa alone in the anal lumen. To correctly establish the intraoperative stage of rectal mucosal prolapse the authors performed a test based on the intrarectal introduction of a large-sized hydrophilic plug, to be extracted later from the anal canal. A total of 40 patients with proctological symptoms and with a diagnosis of rectal mucosal prolapse were submitted, in the outpatient setting, to a minimally invasive test with a small plug and later, in the preoperative stage, in patients under anaesthesia, using a plug entirely inserted into the rectal lumen and extracted via the anus. The same procedure was performed after surgery to verify the results of the excision. In all cases the plug test used in the preoperative stage permitted the perfect surgical evaluation of the extent of the prolapse. The plug test revealed a mucosal prolapse occupying 25% of the anal circumference in 10 patients, up to 50% in 20 patients and more than 50% in 10 patients. The first 30 patients were treated with the transfixed stitch technique, while for the others the Longo surgical technique was preferred. The plug test for the preoperative and postoperative evaluation of rectal mucosal prolapse is an effective tool for obtaining a more precise indication as to the optimal surgical intervention and for verifying the radicality of the surgical excision. The plug test, moreover, proved to be a minimally invasive and easily performed test for evaluating rectal mucosal prolapse.
