Use of the Kono-S anastomosis in pediatric Crohn’s disease: a single-institution experience

Abstract

Objectives

About 24% of children with Crohn’s Disease (CD) require surgery. In 2003, Kono et al. described a novel anastomosis reported to decrease the rate of anastomotic CD recurrence. Subsequent studies have reproduced these outcomes, but none has demonstrated its effect in pediatric patients. This study evaluates short-term outcomes of pediatric patients following ileocolic resection and Kono-S anastomosis.

Methods

A retrospective review of patients < 18 years old who underwent ileocolic resection followed by Kono-S anastomosis compared with those who underwent a stapled anastomosis.

Results

Nine Kono-S patients were matched with nine patients preceding them who received traditional side-to-side and end-to-side anastomoses. All patients underwent minimally invasive surgery. Demographics, pre-operative medication usage, and symptom profiles were not significantly different. Traditional anastomosis (TA) patients had longer lengths of stay (4.6 vs 2.9 days; p = 0.03) but had no statistically significant differences in blood loss, procedure length, and pathologic findings. One Kono-S patient had a superficial surgical site infection, and one TA patient had an anastomotic leak requiring reoperation within 30 days. More TA patients experienced post-operative symptoms at both 30-day and 6-month follow-up (66.7% vs 33.3%; p = 0.16 and 77.8% vs 25%; p = 0.03).

Conclusion

The Kono-S anastomosis appears to be safe in pediatric CD when compared to traditional stapled anastomoses.
