Idiopathic chronic watery diarrhea from excluded rectosigmoid with goblet cell hyperplasia cured by restoration of large bowel continuity.
A 73-year-old woman developed abnormal electrolyte and water loss from an excluded rectosigmoid segment after surgical treatment of a volvulus of the sigmoid colon. Rectal discharges lasted almost for a year, until it spontaneously resolved after restoration of large bowel continuity. Despite extensive investigation, including endoscopic, radiologic, microscopic, bacteriologic and parasitic examinations, no satisfactory explanation of the diarrhea could be found. The histologic pattern of the excluded segment showed a striking increase in mucosal thickness and in number and height of goblet cells. These abnormalities disappeared after closure of the colostomy. Electrolyte composition of the rectal fluid, which contained 134 mmol potassium and 22 mmol sodium per liter was remarkable and similar to that of normal stool water and anal discharges of patients with ulcerative proctitis.
