[Acute intestinal intussusceptions in adults: analysis of 20 cases].

AIM OF THE STUDY

To report our experience in the management of acute intestinal intussusceptions in adults.

PATIENTS AND METHODS

Retrospective study of data of patients older than 15 years who were operated on for acute intestinal intussusceptions from January 1997 to December 2001.

RESULTS

Twelve of the patients were males and eight females with an average age of 41 years (range: 16-71). The clinical and radiological findings were suggestive of bowel obstruction (N = 14), peritonitis (N = 5) and appendicular abscess (N = 1). Correct preoperative diagnosis of acute intestinal intussusceptions was established in 6 cases. Type of intussusception was jejunojejunal (N = 1), ileo-ileal (N = 8), ileocolic (N = 1), ileocecocolic (N = 7) and colocolic (N = 3). Necrosis was found in the intussusceptum in 10 cases and a tumor on the lead point in 14 cases (5 benign lesions and 9 malignant ones). For intussusception involving the colon, all patients underwent en bloc resection with immediate anastomosis, while intussusception located on the small bowel were treated by surgical reduction (N = 1), en bloc resection (N = 8) with immediate (N = 7) or delayed (N = 1) anastomosis. The mortality rate was 15%.

CONCLUSION

In our experience, intussusceptions in adults is not an uncommon clinical entity but correct diagnosis is often established peroperatively. En bloc resection is recommended because of the frequency of neoplasms and bowel ischemia.
