[Repair of mucosa stomal prolapse with circular stapler. Technical note]

Mucosal stomal prolapse is a frequent complication of end colostomies. We describe here an original mucosal colostomy prolapse repair technique using a circular stapling device. This technique stems from the recent introduction of stapled muco-haemorrhoidectomy and was employed on a 68-year-old male patient who had undergone a Miles abdominoperineal excision 17 years earlier. On clinical inspection the patient presented a 5-cm. mucosal stomal prolapse on straining. The surgical procedure was performed under i.v. sedation with midazolam and propofol. After draping the abdomen, the stomal mucosa was gently everted with the aid of three Allis forceps, and a 1.0 prolene purse string suture was created 4-6 cm. cephalad to the cutaneous rim of the stoma. The head of a 33-mm circular stapler was introduced and the purse string suture was tied. The mechanical stapler was prepared and fired, thus obtaining a resection anastomosis of the prolapsed stomal mucosa. No bleeding occurred. A 24-F bladder catheter was placed cephalad to the stapled line and removed on postoperative day one. The patient was discharged from hospital the day after surgery. During a 16-month follow-up neither complications nor relapses have so far been observed. Our technique appears to be simple and safe. We believe it is indicated only for mucosal stomal prolapses, while full-thickness stomal prolapses should be managed by conventional techniques. A larger cohort of patients is needed to confirm our preliminary results.
