Özet

Restorative proctocolectomy (RPC), when performed with a stapled ileal pouch-anal anastomosis (IPAA), allows the retention of the rectal mucosa above the dentate line and can result in disease persistence or recurrence, as well as neoplastic lesions in patients with ulcerative colitis (UC). We report the case of a patient with chronic UC who underwent staple mucosectomy, which is an alternative technique that evolved from stapled hemorrhoidopexy, rather than more traditional procedures. The patient had undergone laparoscopic RPC with a stapled IPAA 2 cm above the dentate line and a temporary loop ileostomy. Because the histopathology showed low-grade dysplasia in the proximal rectum, stapled mucosectomy with a 33-mm circular stapler kit at the time of ileostomy closure was scheduled. Following the application of a purse-string suture 1 cm above the dentate line, the stapler was inserted with its anvil beyond the purse-string and was fired. The excised rectal tissue was checked to ensure that it was a complete cylindrical doughnut. Histopathology of the excised tissue showed chronic inflammation. There were no complications during a follow-up period of 5 months. Because it preserves the normal rectal mucosal architecture and avoids a complex mucosectomy surgery, stapled mucosectomy seems to be a technically feasible and clinically acceptable alternative to the removal of rectal mucosa retained after RPC.
