Cecal volvulus: a report of two cases occurring after the antegrade colonic enema procedure.

BACKGROUND: Many children with chronic constipation and fecal incontinence have benefited from the antegrade colonic enema (ACE) procedure. Routine antegrade colonic lavage often allows such children to avoid daytime soiling. This report describes 2 children in whom the ACE procedure was complicated by a cecal volvulus. METHODS: A retrospective review of 164 children with an ACE procedure was conducted. Two instances of cecal volvulus were identified. RESULTS: The first child presented with abdominal pain and difficulty intubating the ACE site. Over the subsequent day, his pain worsened, and radiographs depicted a colonic obstruction. At laparotomy, a cecal volvulus resulting in bowel necrosis was observed, and resection of the affected bowel and appendix (in the right lower quadrant) and end ileostomy was required. He subsequently had the stoma closed and a new ACE constructed with a colon flap. The second child presented with shock and evidence of an acute abdomen. At laparotomy, a cecal volvulus was noted, and ileocolic resection including the ACE stoma (located at the umbilicus) and an ileostomy and Hartmann pouch was performed. He had a protracted hospital course requiring ventilator and inotropic support. He currently is well and still has an ileostomy stoma. CONCLUSIONS: A high index of suspicion for a potentially life-threatening cecal volvulus should be maintained in children undergoing an ACE procedure who present with abdominal pain, evidence of bowel obstruction, or difficulty in advancing the ACE irrigation catheter.

Outcome of the antegrade colonic enema procedure in children with chronic constipation.

BACKGROUND: Chronic constipation and fecal incontinence in children related to pelvic trauma, congenital anomalies, or malignancy will eventually lead to significant social and psychologic stress. Maximal medical treatment (daily enemas and laxatives) can also be difficult to maintain in many children. METHODS: At our children's hospital, 11 children with chronic constipation or fecal incontinence or both underwent the antegrade colonic enema (ACE) procedure. The operation involved constructing a conduit into the cecum using either the appendix (n = 8) or a "pseudo-appendix" created from a cecal flap (n = 3). We report our surgical results. RESULTS: Mean child age was 9.6 (5 to 18) years. With a mean follow-up of 14 (6 to 24) months, 10 of the children (91%) had significant improvement and 7 children (64%) are completely clean with no soiling and controlled bowel movements after irrigation. CONCLUSIONS: Regular colonic lavage after the ACE procedure allows children with chronic constipation and fecal incontinence to regain normal bowel habits and a markedly improved lifestyle. This procedure should be considered before colostomy in children and adults for the treatment of fecal incontinence from a variety of causes.
