Comparative analysis between subtotal colectomy combined with modified Duhamel procedure and simple subtotal colectomy for severe functional constipation

Abstract

Objective To compare postoperative outcomes and complications between subtotal colectomy combined with modified Duhamel procedure and simple subtotal colectomy for severe functional constipation (SFC). Methods Between January 2006 and June 2010,40 SFC patients after strict but inefficient nonoperative treatments were randomized by number table method to control group (20 cases, receiving simple subtotal colectomy) and combined group (20 cases,receiving subtotal colectomy and modified Duhamel procedure). The selection criteria were normal colonoscopy,and abnormal dynamic proctography (DPG). The functional outcomes after surgery were assessed from 6 months to 2 years period. Results The preoperative clinical manifestations of the two groups were similar. No statistically significant difference was observed between the two groups for time for recovery of the bowel function,length of postoperative hospitalization.and the early postoperative complications (P > 0.05). Functional outcomes of combined group with CIQOL score [(110.5 ±5.0) scores],relieving of costive gastrointestinal symptoms [(79.0 ±6.5)%], recurrent constipation rate [10.0% (2/20)], satisfaction rate of defecation frequency [85.0%(17/20)], satisfaction rate of quality of life[90.0%(18/20)] were significantly better than those of control group[(90.5 ± 3.5) scores, (60.5 ± 2.8)% ,35.0%(7/20), 15.0%(3/20),20.0%(4/20)](P< 0.05). Conclusion Combined application of subtotal colectomy and modified Duhamel procedure for SFC has better outcomes. Key words: Constipation; Colorectal surgery; Modified Duhamel procedure
