A Case of Villous Tumor of the Sigmoid Colon with Watery Diarrhea and Intussusception

Abstract

A 74-year-old man with the complaint of watery diarrhea and dizziness was admitted to our hospital. Blood chemical studies on admission showed hypopotassemia (K 3.2mEq/l) , and the rectal discharge contained high level of potassium (43.1mEq/l) was seen. Contrast enema and endoscopic examination revealed a large villous tumor in the recto-sigmoid. The operative finding showed intussusception due to villous tumor of the sigmoid colon.
We should take careful preoperative management for the patient with villous tumor in the light of possible complications ; electrolyte depletion syndrome and intussusception.
