An alternative management option for colonic atresia preventing loss of the ileocecal valve

Abstract

Purpose Management of colonic atresia is contentious, with primary anastomosis having a notable risk of anastomotic leak. In addition, resection of the terminal ileum and ileocecal (i-c) valve is frequently performed, risking side effects such as diarrhea, vitamin B 12 deficiency, and gall stone formation. Methods The hospital coding system was searched for all patients with a diagnosis of colonic atresia between July 2005 and July 2008. Four term neonates were managed by formation of an ileostomy, a “blow hole” stoma just proximal to the atresia, and a mucus fistula distal to the atresia. Results Average time to full feeds was 7.5 days (range, 3-12 days), and average length of stay was 23 days (range, 13-47 days). Stoma management, problematic in 2 infants, was individualized by a specialist stoma nurse. Ileostomy output was refed into the mucus fistula. Complications included 3 episodes of prolapse of the blow hole stoma in infant 2. All of the infants returned to the operating theater at 1 to 3 months of age for restoration of bowel continuity and closure of the ileostomy. The atretic segment was resected, and an end-to-end anastomosis was performed. Recovery was straightforward in all cases. Conclusion A procedure that retains the i-c valve and most of the colon through creation of a blow hole stoma in the distended proximal colon with a diverting ileostomy and mucus fistula is described. The technique is recommended in selected infants as bowel length and anatomy can be preserved, despite the use of multiple stomas.
