In brief
This retrospective study describes a novel transanal surgical technique for severe pediatric chronic constipation with megarectosigmoid that preserves a 5 cm rectal reservoir. All 13 patients achieved daily voluntary bowel movements with significantly reduced laxative requirements and no fecal incontinence at 6-16 month follow-up.
Written by the GCMD Library team from the article.
Background
At the severe end of the idiopathic constipation spectrum exist patients with chronic idiopathic constipation associated with an enormous megarectosigmoid, among whom few require surgery. We performed transanal proximal rectosigmoidectomy, involving preservation of a 5 cm rectal reservoir, to ameliorate inconsistent and unpredictable outcomes and fecal incontinence occurring in some patients operated on with other techniques.
Methods
We retrospectively observed patients with chronic idiopathic constipation with megarectosigmoid who underwent transanal proximal rectosigmoidectomy during July 2017–May 2018. We analyzed sex, age, operation indication, complications, functional outcome, and time of follow-up. We statistically compared the dosage of laxative before and after the procedure.
Results
Thirteen patients were included in the study. Median age during surgery was 8 years. In 9 cases, the indication for surgery was chronic intake of a daily high dose of Senna with failed weaning trials, and 4 had persistent fecal impaction with laxative-intolerance and refusal of rectal enemas. No intra/postoperative complications occurred. Currently, all 13 patients have daily voluntary bowel movements and no fecal accidents. Laxative dosage was significantly reduced (p = 0.007). Follow-up ranged 6–16 months.
Conclusion
Preliminary results suggest transanal proximal rectosigmoidectomy as an adequate alternative for patients requiring surgery for chronic idiopathic constipation with megarectosigmoid.
