A Case of a Patient with Small Bowel Anisakiasis Requiring Differentiation from Strangulated Intestinal Obstruction Treated with Single-incision Laparoscopic Surgery

Abstract

We report a patient with small bowel anisakiasis requiring differentiation from strangulated intestinal obstruction treated with single-incision laparoscopic surgery. A 38-year-old woman was presented with epigastric pain 4 days after she consumed sushi. Intestinal obstruction was suspected based on her history and abdominal radiographic findings. In addition, strangulated intestinal obstruction could not be excluded, so emergency single-incision laparoscopic surgery was performed. An intestinal stenosis was detected 170 cm from the ileocecal region to the oral side, and partial resection of the small intestine was performed. The patient had a good postoperative course and was discharged on postoperative day 5. Postoperative pathological examination of the resected specimen revealed the presence of Anisakis species larvae, and the diagnosis of small bowel anisakiasis was made. Preoperative diagnosis of this disease may be difficult, but if the possibility of strangulated intestinal obstruction cannot be excluded in patients, laparoscopic surgery to examine the abdominal cavity and determine the treatment according to intraoperative findings may be useful.
