[Colonic J-pouch reconstruction in cases of insufficiency and severe complications after ileocecal pouch in rectal cancer].

In order to reduce the high frequency of bowel movement after resection of the rectum in cases of rectal cancer, the creation of a colonic J-pouch was developed. Meanwhile this operation is well established. As a variation to the standard technique, von Flüe introduced in 1994 the interposition of an ileocecal segment, intended to improve the reservoir function via its own distensibility. Despite the conserved neural and vascular integrity of the ileocecal segment, major complications arise such as pouchitis with necrosis. In these cases, resection of the pouch and permanent discontinuity of stool passage is routine therapy. Patients with permanent stoma face many difficulties both physical and psychological, and often the quality of life diminishes. In the literature there is no detailed case of colonic J-pouch reconstruction following resection of an insufficient ileocecal pouch. This operation is technically highly demanding but feasible.

[Tailgut cyst. Rare differential diagnosis of retrorectal tumors].

Tumors of the retrorectal space are rare entities. The case report of a retrorectal tailgut cyst serves to illustrate the clinical and diagnostic findings, differential diagnosis, and therapy of retrorectal tumors. Tumors in this area can be identified by palpation. The subsequent investigations include ultrasound, endosonography, endoscopy, and by choice computed tomography or magnetic resonance imaging. Usually tailgut cysts are characterized as cystic tumors, well delineated with multicystic formation. The diagnosis has to differentiate between carcinomas of the colorectum, hamartomas, lymphomas, teratomas, chordomas, abscess formation, dermoid cysts, epidermoid cysts, and enteral cysts. An elevated level of CEA may point to malignancy. Complete surgical resection is the therapy of choice.
