A case of sigmoid colon duplication in an adult woman.

Colonic duplication is a rare congenital anomaly that is often diagnosed in childhood, but may go unrecognised until adulthood. It often presents with chronic abdominal pain and constipation, and the preoperative diagnosis may be difficult. We present a case of sigmoid duplication in a 33-year-old Indonesian woman who presented with right-sided colicky abdominal pain and vomiting.

Adult intussusception caused by a lipoma in the small bowel: report of a case.

Adult intussusception represents only about 5% of all intussusceptions and is usually caused by a malignant small bowel lesion acting as the apex of intussusception. We report an unusual case in a male patient of adult intussusception caused by a lipomatous lesion located in the terminal ileum, very close to the ileocecal valve, acting as the lead point. After repeated admissions to several hospitals for investigation of nonspecific abdominal symptoms, the possibility of intussusception was finally raised by a computed tomography (CT) scan of the abdomen.
