Abstract

Background/Purpose: The aim of this study was to investigate long-term outcome and quality of life after the Swenson operation for rectosigmoid Hirschsprung's Disease (HD). Methods: Forty-five patients who underwent the Swenson procedure for HD underwent follow-up for 8 to 16 years. Long-term outcome and quality of life were assessed by interviews and questionnaires including scoring systems. Forty-four healthy children with similar age, sex, and education level distributions used as controls. Results: In 45 patients, 23 (51.1%) had bowel dysfunction. Seventeen patients (37.8%) suffered from fecal soiling. According to the clinical bowel function scoring system, the patients' scores (7.6 ± 2.1) were significantly lower than those of the controls (11.4 ± 0.6; P <.05). Because of poor fecal continence, 25 patients (55.7%) had to restrict their foods. School absence occurred in 6 (13.3%) patients. Seven patients (15.6%) had problems in peer relationships. According to the Quality-of-Life Scoring Criteria, 86.7% patients had good or fair quality of life. The patients' scores (7.7 ± 2.9) were significantly lower than those of the controls (11.6 ± 0.7; P <.05). And the scores of patients who had fecal soiling and incontinence (6.3 ± 2.7) were significantly lower than those of patients without fecal soiling and incontinence (8.4 ± 2.6; P <.05). Conclusions: Although most patients had good or fair quality of life after surgical correction for HD, the long-term outcome and quality of life are not as good as surgeons expected. The bowel function and quality of life of the patients were poorer than those of healthy children. Fecal soiling is very common and affects patients' quality of life. Long-term regular follow-up is indispensable. Close attention should be paid to minimizing bowel dysfunction for patients with HD postoperatively to improve their quality of life.

Materials and methods

Of all the patients operated on from 1984 to 1994 at the second hospital of China Medical University for HD, we were able to obtain clearance to recall 76. To assess the long-term outcome and quality of life, 45 patients included in this report were defined as follows: (1) The patients were from 8 to 16 years old. (2) All patients underwent a modified Swenson procedure. (3) HD was confirmed by an operative rectosigmoid biopsy. (4) All patients had an aganglionic segment confined to the

Stool control

Of 45 patients, 23 patients (51.1%) had long-term bowel dysfunction. Among these, 17 patients (37.8%) had fecal soiling, particularly at night. Three patients (6.7%) suffered from fecal incontinence. Three patients (6.7%) had constipation.

Stool frequency

Twenty-five patients (55.6%) had 1 or 2 bowel movements per day. Eleven patients (24.4%) had frequency of stooling ranging between 3 and 5 bowel movements per day. Three patients had 1 or 2 bowel movements per week. Six (13.3%) patients had increased frequency

Discussion

The functional outcome in patients treated for HD is variable markedly. Many reports showed that the results of surgery for HD were satisfactory. Sherman et al1 reported outcomes with 880 Swenson procedures. At 5 years' or more follow-up, 89.9% of patients had normal bowel habits; this improved to 93.7% at more than 20 years' follow-up. In a large review by Bourdelat et al,2 of 2,430 patients receiving a Duhamel operation, at 15 to 30 years' follow up, the majority of patients achieved good or
