Transanal mucosectomy: a modification of the Soave procedure for Hirschsprung's disease.
In the Soave procedure for Hirschsprung's disease, the mucosectomy of the aganglionic segment of colon is performed transabdominally. The authors describe an innovative modification of the standard Soave procedure, in which a transanal mucosectomy is performed as the abdominal incision is made. The transanal mucosectomy technique was compared with the conventional approach. From 1974 to 1993, 51 patients underwent a Soave procedure for Hirschsprung's disease. Twenty-six (51%) had the standard Soave procedure (STD) (1974-1984), and 25 (49%) had the modified procedure (MOD) (1984-1994). In the latter, the entire mucosal dissection was performed through a transanal approach. Surgical data were accumulated by database analysis. Each case was entered into a database at the time of operation, and follow-up data were obtained through mail-in questionnaires or personal communication. The two groups were comparable with respect to number, gender distribution, and average age at the time of operation. There were two superficial wound infections in the STD group and two superficial wound infections and one death (secondary to cardiac arrest in a patient with trisomy 21 and a severe congenital cardiac anomaly) in the MOD group. The average postoperative stay for the STD group was 10.8 days; that for the MOD group was 6.8 days (t test: P < .0001). The operating time was shorter for the MOD procedure. Follow-up data were available for 25 (96.2%) patients in the STD group and 25 (100%) in the MOD group. The two groups were comparable in all respects except for the average length of follow-up, which was longer for the STD group. No patients had, urinary incontinence or sexual dysfunction (when applicable). Overall, patients/parents in both groups rated the outcome as "good." This modification of the Soave technique for Hirschsprung's disease is both safe and effective. Compared with the standard procedure, it is associated with shorter operating time (because the transanal mucosectomy is performed as the abdomen is opened) and a shorter stay postoperatively. The results have been excellent.
