Abstract
An abdominal wall abscess is uncommon during pregnancy. A 28-year-old woman in the 31st week of gestation was admitted to our hospital for an abscess of the upper abdominal wall along with a high fever. Percutaneous drainage was performed, followed by maintenance on total parenteral nutrition without oral intake for the intestinal fistula. Her total energy intake was 1,640 kcal/day. We confirmed that fetal development was favorable. The fetus was delivered by cesarean section at the 35th week of gestation without low birth weight or congenital anomaly. Radiography and colonoscopy revealed strictures of the ileum and fistulas of the ileum and colon after the cesarean section. Crohn's disease (CD) was suspected on the basis of the findings and the clinical course. She underwent ileocecectomy, resection of the fistulas, and partial resection of the sigmoid colon 2 weeks after the cesarean section. The resected specimen showed some longitudinal ulcers and fistulas of the ileum and cecum, and the patient was diagnosed with CD. She is maintained with diet therapy after surgery. The growth of the infant was also favorable.
