Abstract
A 30-year-old woman in her 27th week of pregnancy was transferred to our hospital with the chief complaints of persistent abdominal pain, nausea and vomiting for 24 hours. She had undergone choledochojejunostomy five years ago for a congenital choledochal cyst. Her vital signs revealed that she was in shock. An abdominal CT showed small bowel dilatation and ascites. Based on the findings, ischemia of the upper part of the small bowel was suspected. Fetal bradycardia appeared as a result of fetal distress. Multiple dilated loops of the small bowel were detected at laparotomy, secondary to internal hernia. The upper ileum was ischemic and necrotic. About 80cm of the small bowel was resected, followed by ileo-ileo anastomosis. Choledochojejunostomy was performed 21 days after the operation, The patient showed good postoperative recovery. Intestinal obstruction during pregnancy is very rare. However, it significantly influences the maternal and fetal mortality rates, typically due to a delay in the diagnosis and proper treatment. Here, we report a rare clinical case, along with a review of the relevant literature.
