The Classification and Surgical Treatments in Adult Hirschsprung's Disease: A Retrospective Study

Abstract

Purpose: To explore the treatments and short-term effects of different types of adult Hirschsprung's disease.

Methods: 89 patients treated in Shanghai Changhai Hospital were retrospectively analyzed. According to the patient's medical history, clinical manifestations, auxiliary examination and postoperative pathological results, the patients were divided into adult congenital megacolon, adult idiopathic megacolon, ganglion cell deficiency (types I and II), toxic megacolon and iatrogenic megacolon, The Treatment methods and short-term prognosis of patients in each group were summarized.

Results: 41 cases of Hirschsprung's disease in adults and low anterior resection or pull-out low anterior resection was performed, and 35 patients with idiopathic Megacolon were treated with one-stage subtotal colon resection under the condition of adequate preoperative preparation. Some patients admitted for emergency intestinal obstruction received conservative treatment first or underwent elective surgery after colonoscopic decompression was improved; two patients with ganglion cell deficiency subtotal colectomy were performed to remove the dilated proximal bowel segment and the narrow distal bowel segment; three patients with toxic Hirschsprung's disease underwent colostomy in mild cases, while subtotal colorectal resection was required in severe cases; Iatrogenic megacolon was diagnosed in eight cases and the optimum operation should be selected according to the specific conditions of patients.

Conclusion: Adult Hirschsprung's diseases were divided into adult congenital hirschsprung's disease, idiopathic Hirschsprung's disease, ganglion cell deficiency, toxic hirschsprung's disease, and iatrogenic Hirschsprung's disease. Different types of surgical treatments for Hirschsprung's disease in adults should be selected according to the specific diagnosis. All patients with adult Hirschsprung's diseases have good short-term outcomes after surgical treatment.
