Colocolic intussusception secondary to colonic adenocarcinoma with impending caecal perforation in an elderly patient: A rare case report

Adult Colocolic Intussusception: A Rare Case of Intestinal Obstruction

“…This condition can be classified according to its location, etiology (idiopathic, benign, or malignant), and the presence or absence of a lead point. Among the three types of gastrointestinal intussusceptions based on location, colocolic intussusceptions (like the case presented here) are the least prevalent in adults, whereas ileocaecal are the most common, followed by enteroenteric intussusceptions [ 3 , 5 , 7 ].…”

“…Intussusception is a rare cause of intestinal obstruction in adults, representing 1%-5% of bowel obstructions and 0.003%-0.02% of all hospital admissions [ 5 , 7 ]. This condition can be classified according to its location, etiology (idiopathic, benign, or malignant), and the presence or absence of a lead point.…”

“…Unlike children, idiopathic cases account for only 8% to 10% of adult intussusceptions. Most (90%) adult intussusceptions have a definable cause, 50% to 75% of which are malignancies [ 2 , 3 , 5 , 8 ].…”

“…The diagnosis of intussusception is complex and rarely made preoperatively since its clinical symptoms are atypical and unspecific. Most patients usually present with obstructive symptoms, chronic abdominal pain, and a palpable mass [ 2 , 5 , 6 , 8 ]. Its complications, such as bowel obstruction, bleeding, infarction, perforation, or peritonitis, may change the clinical presentation [ 8 ].…”

“…Radiological investigations are extremely helpful for diagnosis. Abdominal X-rays, though not sensitive or specific, can show multiple air-fluid levels and a site of intestinal obstruction [ 1 , 2 , 3 , 5 ]. Ultrasonography can be helpful by visualizing the classical "target sign".…”
