title: Pathological classification and diagnosis of intestinal duplication.
abstract: OBJECTIVE
  To determine the pathological classification and the clinical characteristics of intestinal duplication.
  
  
  METHODS
  Eighty-four pediatric patients with intestinal duplication were proved on operation in the last 20 years in the Second Hospital of Harbin Medical University and Harbin Children's Hospital. The pathological classifications were as follows: enteral septum type (2), parietal cyst type (9), parenteral canal type (31), parenteral cyst type (35), and solitary type (1). The clinical presentations and complications included: abdominal mass (24), illius (41), hemorrhage of digestive tract (15) and intestinal perforation with peritonitis (3). Two asymptomatic cases were discovered incidentally.
  
  
  RESULTS
  Among the 84 patients, 82 healed, 1 newborn complicated by intestinal fistula died of septicemia, and the other one died of toxic shock.
  
  
  CONCLUSIONS
  Recognizing the pathological types, common presentations and complications, and applying the corresponding examination methods timely, doctors may improve the diagnostic accuracy.
