Running for the Runs: Intermittent Intussusception From Vanek Tumor Manifesting as Constipation Improved With Exercise.

Abstract

Constipation commonly affects adults and most often results from benign conditions. Certain associated symptoms (e.g., rectal bleeding or weight loss) raise concern for structural pathology and prompt further evaluation. Intussusception uncommonly affects adults and typically presents with abdominal pain and vomiting. Rarely, intussusception manifests with constipation as the primary symptom. We present a case of a patient with new onset constipation who was only able to induce bowel movements after exercising, a compensatory behavior in the setting of recurrent intussusception because of a Vanek tumor.
