Poor knowledge of the disease physiopathology is one of the reasons. METHODS: From January 1977 to December 2003, 430 patients were submitted to surgical treatment for chagasic megacolon. Of these procedures, 351 were elective and 79 emergency operations carried out at the University Hospital of Ribeir\u00e3o Preto. Four elective operations, most frequently used, should be singled out: anterior rectosigmoidectomy (52.71%), left hemicolectomy (18.23%), Duhamel-Haddad operation(15.95%), and total colectomy (5.98%). From the 79 exploratory laparotomies performed on an emergency basis, 53 (67.09%) required intestinal resection. From the 430 patients operated upon, 268 (62.33%) progressed without recurrence of intestinal constipation, and 71 (15.51%) had a recurrence. RESULTS AND DISCUSSION: Based on the data collected, left hemicolectomy had the highest constipation recurrence rate compared to other operating procedures; anterior retosigmoidectomy had less complication episodes and a larger recurrence of intestinal constipation in comparison to the Duhamel-Haddad operation. Emergency operations, mainly for the treatment of volvulus and fecaloma, presented high morbidity and mortality and required extensive intestinal resections, stomas and reoperations.<\/jats:p>","DOI":"10.1590\/s0102-86502008000700015","type":"journal-article","created":{"date-parts":[[2008,5,29]],"date-time":"2008-05-29T02:38:02Z","timestamp":1212028682000},"page":"83-92","source":"Crossref","is-referenced-by-count":23,"title":["Surgical treatment of Chagas megacolon.
