Pediatric Annular Pancreas: A 12-Year Experience
Abstract
Annular pancreas is a rare congenital anomaly that consists of normal pancreatic tissue arranging in a continuous ring around the descending duodenum. This paper reported an experience of 52 pediatric patients with annular pancreas and duodenal obstruction who were treated at the Surgical Department of the Children's Hospital during 1 985- 1996. Thirty-five were male and seventeen were female. Age at onset of symptom ranged from I day to 20 months. Vomiting was the most common presentation in these patients. Jaundice and maternal polyhydramnios were noted in 50 and 21 per cent respectively. All underwent surgical treatment and duodenoduodenostomy was the most common procedure performed. Complete duodenal obstruction with annular pancreas was noted in 35 of 52 cases and their survival rate was 74.3 per cent. Incomplete duodenal obstruction with annular pancreas was found in 17 of 52 patients and the survival rate was 88.2 per cent. The overall survival rate was 78.9 per cent. Congenital heart disease, pulmonary complication, prematurity and septicemia were among the major causes of death.
Our experience from this study suggested that the high incidence of associated serious congenital anomalies resulted in the high mortality in these patients. Duodenal bypass by duodenoduodenostomy was the most popular and effective procedure for correction of duodenal obstruction with annular pancreas.
