title: Adult intussusception: a retrospective review of 41 cases.
abstract: OBJECTIVE
  To optimize the preoperative diagnosis and surgical management of adult intussusception (AI).
  
  
  METHODS
  A retrospective review of the clinical features, diagnosis, management and pathology 41 adult patients with postoperative diagnoses of intussusception was conducted.
  
  
  RESULTS
  Forty-one patients with 44 intussusceptions were operated on, 24.4% had acute symptoms, 24.4% had subacute symptoms, and 51.2% had chronic symptoms. 70.7% of the patients presented with intestinal obstruction. There were 20 enteric, 15 ileocolic, eight colocolonic and one sigmoidorectal intussusceptions. 65.9% of intussusceptions were diagnosed preoperatively using a computed tomography (CT) scan (90.5% accurate) and ultrasonography (60.0% accurate, rising to 91.7% for patients who had a palpable abdominal mass). Coloscopy located the occupying lesions of the lead point of ileocolic, colocolonic and sigmoidorectal intussusceptions. Four intussusceptions in three patients were simply reduced. Twenty-one patients underwent resection after primary reduction. There was no mortality and anastomosis leakage perioperatively. Except for one patient with multiple small bowel adenomas, which recurred 5 mo after surgery, no patients were recurrent within 6 mo. Pathologically, 54.5% of the intussusceptions had a tumor, of which 27.3% were malignant. 9.1% comprised nontumorous polyps. Four intussusceptions had a gastrojejunostomy with intestinal intubation, and four intussusceptions had no organic lesion.
  
  
  CONCLUSIONS
  CT is the most effective and accurate diagnostic technique. Colonoscopy can detect most lead point lesions of non-enteric intussusceptions. Intestinal intubation should be avoided.
