Topic overview
Abstract
Background
Chronic constipation in children is associated with primary megarectum. This study investigated outcomes of surgical treatment of idiopathic megarectum in children.
Methods
This retrospective comparative study included 52 children with idiopathic megarectum (mean age, 9.4 ± 1.7 years) treated from 2007 to 2016. Patients were divided into 2 groups. Group 1 included 23 patients who underwent a Soave pull-through operation. Group 2 included 29 children who underwent laparoscopic low anterior resection with endorectal stapled anastomosis using laparoscopic ultrasound guidance. All patients had clinical and laboratory evaluations with anorectal manometry, colonoscopy and contrast enema studies.
Results
Six patients (26.1%) in Group 1 and one (3.5%) in Group 2 experienced anastomosis leakage requiring colostomy (χ2 = 3.867, P = 0.049). In long-term follow-up, 3 children (13.1%) in Group 1 and 2 (6.9%) in Group 2 had ongoing constipation; this difference was not significant. Frequent loose stools with soiling were significantly more common in Group 1 (14 patients; 60.9%) than in Group 2 (4 patients; 13.8%) (χ2 = 10.566, P = 0.001).
Conclusions
Our experience shows that laparoscopic video-assisted low anterior resection of the colon with endorectal stapled anastomosis under laparoscopic ultrasound guidance to determine the level of colon resection is the better operation then Soave for children with idiopathic megarectum and chronic constipation. This approach provides good functional results and reduces complications.
Type of study
