A 56-year-old woman presented to the emergency department with severe abdominal distention. She was under treatment of psychosis with Risperdal (risperidone) and Largactil (Chlorpromazine hydrochloride) for 15 years. She was taking akineton (Biperiden HCL) to prevent side effects of anti-psychotic treatment. Diagnostic studies revealed severe faecal impaction in the rectosigmoid colon. Emergency laparotomy was performed and impacted fecalith was removed. All the diagnostic studies after the surgery were inconclusive for the reason of the fecalith impaction other than her medication for psyhosis.
