BACKGROUND: Esophagocoloplasty in advanced chagasic megaesophagus is seldom necessary. But, when realized, brings with it a major incidence of complications. AIM: To verify the complications following esophagus reconstruction by esophagocoloplasty in patients with previous gastrectomy submitted to transmediastinal esophagectomy for chagasic megaesophagus end-stage. METHODS: From July 1983 to April 2009, 204 patients with chagasic megaesophagus stage III and IV were submitted to esophageal resection at the Surgery Department at the Hospital Celso Pierro Puc-Campinas, Brasil. Ninety-two patients had the procedure done by esophageal mucosectomy; 84 under-went a transhiatal esophagectomy and in 38, esophagectomies were done through a transthoracic approach. In 194 patients (95%) the reconstruction was done by gastric interposition and in the 10 remaining patients (5%) it was by transposition of the transverse colon. This procedure was recommend due to previous gastrectomy done in all patients. All of them were male with average age of 47.5 years old. RESULTS: Seven patients (70%) developed one or more complications, either systemic or local. Among the systemic complications, one patient had thrombophlebitis in the lower extremity, with good recovery; one had a myocardial infarction with fatal evolution; three patients (30%) had pulmonary infection with good recovery. Amongst the local complications, four patients had cervical anastomotic leak with satisfactory recovery with conservative treatment. Five had cervical anastomotic stricture between the 35th and the 63rd post-operative day, with good recovery after endoscopic anastomotic dilatations. From the eight patients followed during this period, six (75%) had good deglutition for solids and/or semi-solids, and satisfied with the surgery since were able to return to their regular diet. CONCLUSIONS: Despite the fact that the esophagocoloplasty results in a good deglutition and quality of life, in short and medium terms, it must be considered a surgical technic with high morbidity in gastrectomized patients.
