Purpose

To identify the clinical features in diagnosis and treatment of Hirschsprung's disease (HD) associated with Down syndrome (DS), the authors retrospectively analyzed data for patients with DS from the past 3 nationwide surveys in Japan. This survey was already approved by the Japanese Society of Pediatric Surgeons.

Methods

Patient data were collected in 3 phases—phase I (1978-1982), n = 47; phase II (1988-1992), n = 79; and phase III (1998-2002), n = 90. In total, data on 216 patients (5.6 % ) of 3852 were collected and analyzed.

Results

The incidence of DS in patients with HD was 2.9 % , 7.1 % , and 8.2 % in phases I, II, and III, respectively, with a corresponding male/female ratio of 5:1, 2.4:1, and 5:1. The ratio of the extent of aganglionosis was nearly consistent across all phases. In phases I, II, and III, the incidence of total colonic aganglionosis was 2.1 % , 0 % , and 2.2 % ; and that of cardiovascular anomalies, 36.1 % , 45.6 % , and 55.6 % ; and that of preoperative enterocolitis, 31.0 % , 26.6 % , and 24.4 % . The 2 most common surgical procedures were the Soave procedure, including transanal endorectal pull-through, and Duhamel procedure including Z-shaped anastomosis. The mortality rate decreased over time, from 26.1 % in phase I to 11.4 % in phase II and 7.8 % in phase III. Almost all mortality cases were associated with cardiovascular anomalies: 54.5 % , 62.5 % , and 85.7 % in phases I, II, and III, respectively.

Conclusions

The incidence of HD with DS has increased over time. The number of male patients and cardiac anomalies has also increased in the last 10 years. Total colonic aganglionosis was rare. A marked decrease in the overall mortality rate was observed.
