Abstract

AIMS:

Transcutaneous electrical stimulation (TES) was used to treat children with slow-transit constipation (STC) for 1 to 2 months in a randomized controlled trial during 2006 to 2008. We aimed to determine long-term outcomes, hypothesizing that TES produced sustained improvement.

METHODS:

Physiotherapists administered 1 to 2 months of TES to 39 children (20 minutes, 3 times a week). Fifteen continued to self-administer TES (30 minutes daily for more than 2 months). Mean long-term follow-up of 30 of 39 patients was conducted using questionnaire review 3.5 years (range 1.9-4.7 years) later. Outcomes were evaluated by confidence intervals or paired t test.

RESULTS:

Seventy-three percent of patients perceived improvement, lasting more than 2 years in 33% and less than 6 months in 25% to 33%. Defecation frequency improved in 30%. Stools got wetter in 62% after stimulation and then drier again. Soiling improved in 75% and abdominal pain in 59%. Laxative use stopped in 52%, and 43% with appendicostomies stopped washouts. Soiling/Holschneider continence score improved in 81% (P = .0002). Timed sits switched to urge-initiated defecations in 80% patients. Eighty percent of relapsed patients elected to have home stimulation.

CONCLUSION:

TES holds promise for STC children. Improvement occurred in two thirds of children, lasting more than 2 years in one third, whereas symptoms recurred after 6 months in one third of children.
