Small Study Assesses Robotic Pull-Through for Secondary Megarectum After Anorectoplasty
A study published in BMC Pediatrics (2026) evaluated the feasibility and safety of using a da Vinci robotic system to perform pull-through surgery for secondary megarectum in children with recurrent constipation after anorectal malformation repair. The analysis included eight patients aged between 30.4 and 50.6 months. Postoperative assessments using the 2005 Krickenbeck classification showed that seven of the eight patients experienced improvement in constipation, with five achieving complete symptom resolution. Histopathological examination revealed structural changes such as thickened nerve plexuses and degenerative muscle fibers without ganglion cell abnormalities. The authors conclude that while the robotic approach enabled precise dissection, larger studies are needed to validate these results.

A small clinical cohort of eight pediatric patients demonstrated that da Vinci robot-assisted pull-through surgery is feasible and safe for resecting secondary megarectum following anorectoplasty, with seven out of eight showing improved constipation symptoms; however, the authors explicitly note that larger comparative studies are required to confirm these preliminary findings.

A da Vinci robot-assisted pull-through procedure used to resect secondary megarectum in children experiencing recurrent constipation after anorectal malformation surgery proved feasible and safe, relieving constipation in seven out of eight patients evaluated in a clinical cohort. Some pediatric patients with anorectal malformations acquire secondary megarectum following anorectoplasty, an outcome that leads to intra

ed cohort comprised five males and three females, consisting of three patients with intermediate-type anorectal malformations and five with low-type malformations. At the time of the robotic resection, patient ages ranged from 30.4 to 50.6 months, with a median age of 38.8 months.

Five of these children attained complete symptom resolution from baseline grade 3 constipation, two children improved from grade 3 to grade 1 constipation, and one child remained unchanged at grade 3. Furthermore, among the six patients who exhibited preoperative soiling, five experienced improvement following surgery, whereas one patient showed no change and remained at grade 1. Pathological analysis of the r
