Abstract
Objectives To introduce a new technique for intestinal anastomosis when performing demucosalized enterocystoplasty. Methods In 8 dogs, a vascularized seromuscular patch of sigmoid colon was harvested without opening the bowel lumen. The bowel mucosa was invaginated into the intestinal lumen and the sigmoid musculature was reapproximated. Twelve patients underwent a nonsecretory sigmoid cystoplasty following the same principle. Results No complications occurred in the experimental animals. The animals were fed normally starting on the first postoperative day. Prolapse of the excess mucosa occurred in 3 cases and disappeared spontaneously. In the clinical group, the postoperative course was normal. Oral intake was resumed on the first day after the operation. The hospital stay was shorter than that of patients in whom the bowel lumen was opened. Conclusions The use of demucosalized intestinal patches without opening the intestinal lumen appears to be feasible and is expected to reduce perioperative morbidity. Extensive bowel preparation can be reduced, as can the prophylactic use of antibiotics.
