| Abstract |
Purpose
: Although air enema reduction has been known as a good method of diagnosis and treatment of intussusception, it could develop colon perforation. However, there have been few studies about this complication. So we analyzed the risk factors of colon perforation during air enema reduction in patients with intussusception.
Methods
: We reviewed the charts of 12 colon perforation patients during air enema reduction of intussusception, who were admitted to Gil Medical Center from Jan. 1990 to Dec. 2001. Their age, sex, major symptoms, length of time till hospital visit, types of intussusception, operative findings and pathologic reports were reviewed.
Results
: Among 657 cases, 596 patients(90.7%) were successfully treated, but 12 patients(1.83%) failed in air enema reduction and had colon perforation. In patients with colon perforation the male to female ratio was 11 : 1, and average age was 5.3 months. The most common symptom at the time of hospital visit was vomiting(91.7%). Cyclic irritability(75.0%), bloody stool(75.0%) and abdominal mass(41.7%) were also noted. The average length of time between symptom onset and hospital visit was 44.7 hours. Types of intussusception were predominantly ileocolic, ileocecal, and ileoileocolic. The site of perforation was most commonly found at the proximal part of intussusception including ascending colon(50%) and transverse colon(50%). Most cases were uncomplicated, and had a single perforation. Pathologic reports showed hemorrhagic necrosis and mesenteric laceration at the site of colon perforation. Complications of colon perforation were tension pneumoperitonium(58.3%), requiring immediate decompression.
Conclusion
: The chance of colon perforation during air enema reduction increases in cases with small bowel obstruction on simple abdominal x-ray of a patient younger than 6 months, delay in time till hospital visit and higher air pressure during reduction. Therefore more careful investigation is needed in these cases. |
