We report two cases of Chagas' disease with megacolon who presented with chronic diarrhea. One of the patients also had evidence of malabsorption, such as steatorrhea and hypocalcemia. Barium meal follow-through showed remarkable dilation of the jejunum in both cases and, in one of them, an associated megaduodenum. Manometric studies of gastrointestinal motility showed abnormally slow propagation of the interdigestive migrating motor complex, which was also excessively prolonged. Cultivation of jejunal aspirates revealed strict anaerobic bacterial growth in both cases. Oral antibiotic therapy led to substantial improvement in symptoms. The two cases herein reported indicate that clinical manifestations of small bowel bacterial overgrowth, possibly caused by motor disturbances associated with megajejunum, may occasionally include the clinical picture of gastrointestinal involvement in Chagas' disease.

Pseudoachalasia is a rare clinical entity with clinical, radiographic, and manometric features often indistinguishable from achalasia. Primary adenocarcinomas arising at the gastroesophageal junction or a tumor of the distal esophagus are the most frequent causes of pseudoachalasia. Rarely, processes other than esophagogastric cancers including chronic idiopathic intestinal pseudo-obstruction, amyloidosis, sarcoidosis, Chagas' disease, vagotomy, antireflux surgery, pancreatic pseudocysts, von Recklinghausen's neuroinomatosis, gastrointestinal stromal tumor, and other malignancies and rare genetic syndromes, may lead to the development of pseudoachalasia. Secondary achalasia is extremely rare, with less than 100 cases reported in the literature so far. Gastrointestinal manifestations in primary or secondary amyloidosis include abdominal pain, diarrhea, constipation, malabsorption, obstruction, motility disturbance, intestinal infarction, perforation, and hemorrhage; however, gastrointestinal tract involvement is asymptomatic in most instances. We present here a rare case of multiple myeloma initially presenting with dysphagia because of esophageal amyloidosis and manometric findings typical of achalasia.
