Recurrent colonic intussusception due to a lipoma of the transverse colon at the background of congenital dolichocolon and chronic constipation.

Colonic intussusception caused by benign tumour in adults is uncommon condition. Lipoma as benign tumour arises from submucosal layer of gastrointestinal tract and derives from mature adypocytes. It is usually small asymptomatic lesion and reveals during colonoscopy, CT, surgery or autopsy accidentally. However, in cases with large size it may cause abdominal pain, constipation, diarrhoea, anaemia, bleeding or intussusceptions. We present a 52-year-old female patient with colonic intussusception caused by lipoma of the transverse colon and with congenital dolichocolon. The patient had several episodes of bowel obstructions which were treated conservatively. We performed elective open extended right hemicolectomy, ileotransversostomy end-to-end.
