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. [5]
This work has been reported in line with the SCARE criteria. [6]
