2 cases of secondly small bowel atresia

Abstract

We reported 2 cases of atresia of the small bowel on the postoperative course and discussed about the etiology. First case was 1-year-old female. She was made a diagnosis of incarcerated para-duodenal hernia and operated. The involve intestine seemed viable, so we did not resect it. After the operation, she repeated the intestinal obstruction. She was made an operation again on 43rd days after the first operation. We found an atresia of the jejunum (type I). Second case was 15-year-old female. She had mental retardation and admitted to our institution. Severe deformities were found on her spinal and pervic bone. The small bowel was incarcerated in the stenotic minor pelvic space. She was made an operatin. When we released her intestine, it seemed viable and was not resecte. On 30th post operative days, she showed the intestinal obstruction again. Surgical treatment was necessary for her condition, but we could not because she had severe pneumonia. It was a cause of her death on 102nd days after the operation. We found ileal atresia (typeIII a) and torsion of the mesentery at autopsy. Recent concept holds that atresia of the small bowel may result from a impaired vascularity. We think these 2 cases suggested this concept.
