Early adult outcome of the Duhamel procedure for left-sided Hirschsprung disease—a prospective serial assessment study

PurposeTo assess both early adult functional outcome and change in long-term functional outcome over time after the Duhamel procedure (DP) for left-sided Hirschsprung disease (HSCR).MethodsThe study population consisted of 78 children (aged 19.9 ± 3.6 years) who previously underwent objective outcome assessment after DP was performed for HSCR during the period of 1980 to 1991. Inclusion criteria were previous evaluation of functional outcome and either rectosigmoid or left-sided HSCR. Outcome measures were assessed twice within the cohort, in 1997 and in 2005. The primary outcome measure was the Rintala (J Ped Surg. 1995;30:491-494) functional outcome score (FOS; maximum, 20). Controls consisted of 20 age-matched healthy children. Satisfactory functional score was defined as an FOS at or above the 10th percentile of controls (FOS, ≥17). Secondary outcome measures were the operation failure rate (defined by requirement for a stoma or major reoperative surgery), and enterocolitis rates (defined by intention to treat). Consecutive outcome scores were compared by paired t test. Data were expressed as mean ± SD, and P < .05 was considered significant.ResultsOperation failure occurred in 9 (11.5%) of 78. Consecutive FOSs were obtained in 40 (57%) of 69. A satisfactory functional score was observed in 23 (58%) of 40 adults as opposed to 33 (47%) of 70 children 8 years previously (P = .02). Satisfactory outcome (defined by satisfactory functional score and lack of enterostomy or major revision pull-through procedure) was observed in 23 (47%) of 49. Previously, this figure was 34 (44%) of 78. Individual paired FOSs showed a significant improvement with time (1997: 14.9 ± 4.1; 2005: 16.4 ± 2.8; P = .02).ConclusionsAt early adult follow-up, the operation failure rate has not changed from that of the same cohort 8 years earlier. However, a significant improvement in individual FOSs was demonstrated.
