Transanal rectosigmoid resection for severe intractable idiopathic constipation

Introduction

Idiopathic constipation is a source of significant morbidity in children. A subset of patients is refractory to medical therapy and requires surgical intervention. We present a novel surgical technique for the management of these patients.

Methods

We reviewed the records of 288 patients with severe idiopathic constipation and soiling. Patients who were refractory to medical management and had a megarectosigmoid underwent a transanal full-thickness rectosigmoid resection with a primary colo-anal anastomosis.

Results

Fifteen patients underwent a transanal rectosigmoid resection. The preoperative contrast enema demonstrated an enormously dilated rectosigmoid in 14. An average of 43 cm (range, 8-98 cm) of rectosigmoid was resected. Of 14 patients with more than 3 months of follow-up, the preoperative laxative dose was 68 mg of senna/d (range, 52-95 mg), which decreased to 8.6 mg postoperatively (P < .001). Nine patients are clean without soiling, 1 is more prone to diarrhea, but is clean. Two patients soil occasionally, but are noncompliant, and 2 were lost to follow-up.

Conclusion

Transanal rectosigmoid resection for medically intractable idiopathic constipation resulted in a dramatic reduction or elimination in laxatives use while preserving continence. It is a useful alternative to surgical options such as other colonic resections, antegrade enemas, and stomas.
