An 86-year-old woman complaining of right lower abdominal pain was admitted to our hospital. During history-taking, she revealed that she had eaten a yellowtail fish two days earlier. Abdominal computed tomography (CT) revealed thickening of the small intestinal wall with a linear calcification inside, and a small amount of air in the mesentery. Based on her history, we suspected fishbone perforation of the small intestine and performed emergency single-incision laparoscopic surgery. The fishbone was removed and the perforation in the small intestine was closed by suture. The patient was discharged on day 8 after the surgery. We report a case of small intestinal perforation caused by a fishbone that was successfully treated by single-incision laparoscopic surgery.
