Introduction:
Intussusception means telescoping of a proximal segment of the bowel (intussusceptum) into the lumen of the adjacent distal segment (intussuscipiens). Rarely the opposite could happen, which is known as retrograde intussusception. [2]
Intussusception is very uncommon in adult patients, with one to three cases occurring in a population of 1 000 000 per year, which puts it at the bottom of the list of differential diagnoses of abdominal pain, and more often, it may not be counted. Its aetiology differs significantly between children and adults. Adult intussusception of the colon is most likely secondary to a malignant tumour. [3]
In both small- and large-bowel intussusception, the lipoma is the most common benign tumour and adenocarcinoma as the common malignant leading point. [4]
The diagnosis is commonly surprised at laparotomy, as most patients present as an emergency with intestinal obstruction. Usually, in stable patients, the diagnosis can be challenging as symptoms, mainly intermittent abdominal pain and clinical examination and investigations are often negative, and the patient will probably be labelled with irritable bowel syndrome.
