[Incidence of symptomatic megacolon in patients with chagasic megaesophagus]. / Incidência de megacólon sintomático em portadores de megaesôfago chagásico.

The authors analyze the incidence of megacolon associated to megaesophagus during a 7 year period. Of the 192 patients with megaesophagus only 15 who presented associated intestinal symptoms were further investigated through barium enema. No statistically significant differences were found between the group with megaesophagus and the group presenting association of megaesophagus and megacolon as to sex and age of the individuals and severity of megaesophagus. The esophageal symptoms preceded the intestinal symptoms in 93.3% of the cases. Many treatments were used, but recently good results were obtained by the association of Heller's cardiomyotomy with modified Lortat-Jacob's technique and left hemicolectomy.
