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.

Transverse colon duplication with chronic constipation in adult.

Gastrointestinal duplications are extremely rare congenital abnormalities having definite difficulties to be diagnosed preoperatively. Most of them are presented at the oesophagus and ileum and only involve colon from 4% to 18%. We illustrate a case report of an 18-year-old female patient with transverse colon duplication. There were symptom manifestations such as chronic constipation with flatulence accompanied with abdominal pain. We demonstrate this case report due to non-specific clinical presentation and some difficulties to form preoperative diagnosis. The patient underwent surgery. Tubular transverse colon duplication communicated with normal bowel in the proximal part was revealed. We performed transverse colon resection with duplication. The postoperative period was uneventful.
