Fecal impaction is common in elderly, bed ridden, schizoaffective patients on antipsychotics. Intestinal obstruction due to distal colonic fecaliths is rare as it is amenable to digital manual evacuation and enemas. Our patient presented with abdominal distention, with last bowel evacuation reported 3 months ago. Computed tomography (CT) abdomen demonstrated a huge sigmoid fecalith causing bilateral hydronephrosis. He was managed through laparotomy with sigmoid colon resection and end colostomy.
