Clinical presentations, diagnosis and treatment of adult intussusception, a 20 years survey

AbstractBackgroundIntussusception is a rare cause of intestinal obstruction in adult patients. The etiology of malignant nature has been reported to be more frequent in this group and the diagnosis is usually made at operation. Few reports are published for this clinical entity from Middle East.MethodsThe medical records of all adult patients admitted with the diagnosis of intussusception in a tertiary care center between 1989 and 2009 were reviewed.ResultsThere were 15 cases of intussusception in this 20 years period. The mean age of patients was 33.6 years, 8 females and 7 males. In 14 cases the leading point of intussusception was in small bowel. Resection and primary anastomosis was the selected procedure in 13 patients; one patient underwent colostomy and one reduction alone. Malignant cause was detected in only 2 cases. 7 Patients were operated on with diagnosis of intussusception according to imaging findings. The diagnosis was made at operation in the remaining 8 cases. Only one anastomotic leakage occurred in patient on systemic steroids.ConclusionThe mean age of our patients is relatively low with more benign etiologies in small bowel. The CT scan may be the most helpful imaging modality in suspected cases but decision for operation in acute presentations should not be deferred for definite diagnosis. Resection of the involved bowel segment and primary anastomosis is associated with a good outcome
