Article Synopsis
- The study aimed to assess the long-term gastrointestinal effects of pyloromyotomy in children who had undergone this surgery for infantile hypertrophic pyloric stenosis (IHPS) from 2007 to 2017.
- A questionnaire, including the Pediatric Quality of Life Inventory™ Gastrointestinal symptoms module, was completed by 199 participants, revealing that their GI symptoms scores were similar to those of healthy peers.
- The results suggest that long-term GI issues after pyloromyotomy are rare, indicating no significant difference in health outcomes between these children and healthy controls, which can help inform parents and lessen the need for extensive follow-up care.
Background: Functional constipation is common in children and accurate diagnostic methods are essential for early diagnosis and effective management. The diagnostic accuracy of transabdominal ultrasound to diagnose functional constipation is unclear.
Objective: To evaluate the diagnostic accuracy of transverse rectal diameter measurement via transabdominal ultrasound in diagnosing children with functional constipation and in identifying fecal impaction.
Background: Despite optimal conservative and medical treatment, some children with functional constipation (FC) continue to experience symptoms. Antegrade continence enema (ACE) surgery has been suggested as the primary surgical option after less invasive pharmacological and non-pharmacological interventions have not been effective. The purpose of this systematic review was to assess the outcomes of ACE for children with FC.

Objectives: The understanding of the impact of tethered cord syndrome (TCS) on the physiology of the colorectal area is limited. Our aim was to describe anorectal and colonic motility in children with TCS and compare the findings to those of children with functional constipation (FC).
Methods: We conducted a retrospective review of children with TCS who had an anorectal manometry (ARM) performed at our institution from January 2011 to September 2023.
Background: Our objective was to evaluate long-term outcomes of sacral nerve stimulation (SNS) for children with functional and organic defecation disorders.
Methods: We performed a prospective study of children <21 years of age who started SNS treatment between 2012 and 2018. We recorded demographics, medical history, and diagnostic testing.
