Cholangiocarcinoma presenting with severe gastroparesis and pseudoachalasia.

Tumor-associated gastroparesis, though reported in association with various malignancies, is rare in patients with cholangiocarcinoma. We report a 55-year-old woman who presented with dysphagia and recurrent vomiting. Esophagogastroduodenoscopy revealed dilated stomach and excess residue without organic obstruction. 99mTc sulfur colloid solid gastric emptying study, radio-opaque marker gut transit study, and esophageal manometry showed features suggestive of gastroparesis and achalasia cardia; electrogastrography revealed bradygastria. Cholangiocarcinoma was detected on CT scan performed after the patient developed jaundice two months later. The lesion was deemed surgically unresectable. She died four months later.
