Background: Children with functional constipation require prolonged laxative administration for proper emptying. Whether these laxatives can be weaned after better functioning is achieved is unknown. We aim to describe a standardized protocol for stimulant laxative weaning and its early outcomes.

Methods: Patients were candidates for weaning if they had been on a stable laxative dose for six months, defined as one bowel movement per day with no soiling, impaction, or enemas. Laxative dose was decreased by 10-25% with re-evaluation every two weeks. If patients remained well without constipation, dose was weaned further by 10-25%. If there were worsening of symptoms, lower dose was maintained for 3-6 months until re-evaluation.

Results: There were a total of sixteen patients evaluated. Median age was 12.7 years [IQR: 11.7-15.3] with laxative duration of 8.0 years [IQR: 5.4-10.7]. All patients were on senna; some were on fiber. Median starting senna dose was 71.3 mg [IQR: 54.3-75.0] and median fiber dose was 5.5 g [IQR: 4.0-6.0]. As of most recent follow up, nine patients (56.3%) had weaned off laxatives in 3.7 months [IQR: 1.3-11.6]. For those still on laxatives, median reduction in dose was 41.4 mg [30.0-75.0], and over half weaned their dose by >50%. Almost all (90.9%) of those on high doses were able to wean.

Conclusion: A standardized laxative weaning process can be successful in patients with functional constipation, especially on high doses. Further prospective studies will be necessary to confirm the success of this protocol.

Level Of Evidence: III.

Article Synopsis
  • The study examines the use of antegrade continence enemas (ACE) in children with medically refractory fecal incontinence and constipation, focusing on patient perceptions and the potential to discontinue the use of the associated appendicostomy/cecostomy tube.
  • Data was gathered from 165 patients who underwent ACE procedures between 2012 and 2021, with 82 completing a follow-up survey revealing satisfaction rates and reasons for discontinuing flushes.
  • Findings indicate a high satisfaction rate (76.8% very satisfied), with 21.8% of patients able to stop using flushes for various reasons, and a strong recommendation rate for ACE among respondents.

Pseudo-Bartter/Gitelman syndrome (PBS/PGS) is a disorder that presents with hypokalemia and metabolic alkalosis resembling Gitelman syndrome (GS) due to secondary factors, such as lifestyle and /or medicines. Notably, PBS/PGS is more likely to cause renal dysfunction than GS. We report the first case of PBS/PGS due to long-term laxative abuse leading to end-stage kidney disease (ESKD).
