Summary
This study introduces a novel demucosalized intestinal patch technique for enterocystoplasty, avoiding bowel lumen opening. This method shows promise for reducing complications and hospital stays in patients undergoing intestinal surgery.
Area of Science:
- Urology
- Surgical Innovation
- Gastroenterology
Background:
- Enterocystoplasty, a procedure to augment the bladder using intestinal segments, traditionally involves opening the bowel lumen.
- Opening the bowel lumen can increase the risk of complications such as infection and prolonged recovery.
- A novel technique is needed to minimize morbidity associated with enterocystoplasty.
Purpose of the Study:
- To present a new surgical technique for intestinal anastomosis during demucosalized enterocystoplasty.
- To evaluate the feasibility and safety of this novel approach in experimental animals and human patients.
Main Methods:
- A vascularized seromuscular patch of sigmoid colon was harvested without opening the bowel lumen in 8 dogs.
- The bowel mucosa was invaginated, and the sigmoid musculature was reapproximated.
- Twelve patients underwent nonsecretory sigmoid cystoplasty using the same principle.
Main Results:
- No complications were observed in the experimental animals, with normal feeding initiated on postoperative day 1.
- In clinical cases, the postoperative course was uneventful, with oral intake resumed on day 1 and shorter hospital stays compared to traditional methods.
- A minor complication of mucosal prolapse occurred in 3 patients but resolved spontaneously.
Conclusions:
- The demucosalized intestinal patch technique, without opening the intestinal lumen, is feasible for enterocystoplasty.
- This approach is anticipated to decrease perioperative morbidity, reduce the need for extensive bowel preparation, and lower prophylactic antibiotic use.
