Intussusception Caused by Colonic Tumors in Elderly Patients: A Case Series of Seven Patients

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

“…Laboratory investigations were within normal limits with hemoglobin of 12.3 g/dL [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , total leucocyte count of 10,000/μL, platelets of 359,000/μL, serum sodium of 146 mEq/L, serum potassium of 4 mEq/L, random blood sugar level of 5.1 mmol/L, urea of 3.3 mmol/L, and creatinine of 76 μmol/L.…”

“…In the majority of cases, the precipitating lesion is a bowel malignancy, thus making surgical resection the preferred choice of treatment for intussusception in adults [3] , [4] . Other causes include post-trauma, Meckel's diverticulum, postoperative adhesions, lipomas, and adenomatous polyps [5] .…”

Rare differential for large bowel obstruction

“…Unlike in children, it usually has a definitive organic aetiology in over 90% of cases . A malignant intestinal lesion is often the cause of intussusception in adults . In total, 70–90% of adults with intussusception require definitive surgical management .…”

“…Intussusception in adults accounts for approximately 5% of all cases of bowel obstruction . Preoperative diagnosis of intussusception is challenging, particularly in elderly patients, as the clinical findings are commonly not specific . Patients often present with clinical findings similar to a subacute or chronic bowel obstruction.…”

“…Computed tomography imaging often depicts classical features that include a ‘sausage‐shaped’ mass in the longitudinal axis and as a ‘target’ mass in the transverse axis . Surgical resection is recommended due to the likelihood of underlying malignancy, especially in colonic lesions and the risk of resultant intestinal ischaemia . Reduction of the intussusception prior to resection may minimize the extent of the resection but where malignancy is suspected, en bloc resection is recommended to reduce the risk of perforation and tumour seeding .…”
