RESUMEN
OBJECTIVE: The aim of this study was to assess the efficacy of a cognitive-behavioral approach to the treatment of recurrent abdominal pain caused by childhood functional gastrointestinal disorders (FGIDs). METHODS: From September 2001 to December 2002, 18 patients (12 male; mean age, 12.1 +/- 4.9 years) with chronic abdominal pain (mean duration, 11.8 +/- 13.3 months) caused by FGIDs were referred to our facility's mind-body institute (MBI). Treatment included guided imagery and progressive relaxation techniques. The mean number of sessions per patient was 4.3 +/- 3.4. Outcomes included change in abdominal pain and quality of life, evaluated by the Pediatric Quality of Life Scale (PedsQL). Follow-up was 10.6 +/- 2.3 months after the last MBI session. RESULTS: Abdominal pain improved in 89% of patients; weekly pain episodes decreased from 5.5 +/- 0.9 to 2.0 +/- 2.7 (P < 0.05); pain intensity (0 to 3 scale) decreased from 2.7 +/- 0.6 to 0.6 +/- 0.7 (P < 0.04); missed school days/month decreased from 4.6 +/- 1.7 to 1.4 +/- 3.2 (P < 0.05); social activities/week increased from 0.3 +/- 0.6 to 1.3 +/- 0.6 (P < 0.05); physician office contacts/year decreased from 24 +/- 10.2 to 8.7 +/- 13.1 (P = 0.07). PedsQL scores (0 to 100 scale) improved from 55.3 +/- 11.9 to 80.0 +/- 10.7 (P < 0.03). CONCLUSIONS: Guided imagery and progressive relaxation can safely and effectively reduce chronic abdominal pain in children with FGIDs. This treatment also improved social functioning and school attendance.
