Background: Operative maneuvers to increase mesenteric length during ileal pouch-anal anastomosis (IPAA) are frequently utilized in adults, but limited data exist on the need for their use in children. Materials and Methods: A retrospective chart review of children (age <18) considered for IPAA creation at two affiliated tertiary referral centers from 2007 to 2017 was conducted, and patient factors, operative details, and 30-day postoperative complications were abstracted. Body mass index (BMI) was normalized to BMI percentile-for-age-and-sex and classified as underweight (BMI <5th percentile), healthy weight (5th ≤ BMI percentile <85th), or overweight/obese (BMI ≥85th percentile). Maneuvers were identified from operative notes. Univariate analysis and multivariable logistic regression were performed to determine independent factors associated with the use of maneuvers. Results: A total of 94 patients underwent attempt at IPAA creation, which was successful in 91 (97%). Fourteen (15%) of 91 patients were classified as overweight or obese. The 3 failures occurred secondary to inability to reach in 3 patients, with specific mention of patients' obesity in 2 and pouch ischemia in 1. Sixty (66%) patients required maneuvers to lengthen the mesentery. Overweight/obese patients required maneuvers more often than nonoverweight/obese patients (93% versus 61%, P = .03). There were no differences in 30-day maximum Clavien-Dindo scores between patients with and without maneuvers performed (P = .83). Being overweight/obese was an independent risk factor for requiring maneuvers (odds ratio: 9.3, 95% confidence interval: 1.1-82.8) after adjusting for age, sex, height, operative stage, and surgeon. Conclusion: Surgeons should be prepared to perform mesenteric lengthening maneuvers when operating on pediatric patients to ensure minimal tension on the IPAA, and more so when operating on obese children. Whether these maneuvers have an impact on long-term pouch function is undetermined.
