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.
