Abstract
A 10-year-old girl was admitted to our hospital with abdominal pain. Computed tomography (CT) showed acute appendicitis, necessitating emergency laparoscopic appendectomy. A gangrenous appendix and purulent ascites were observed in the intraperitoneal space during laparoscopy, suggesting perforated appendicitis. The appendix was resected at its root. The right outer inguinal ring was slightly enlarged. The patient's postoperative course was uneventful ; however, on postoperative day 7, the patient had right inguinal pain. CT showed an abscess in the right inguinal canal. It was postulated that purulent ascites due to perforated appendicitis tracked into the right inguinal canal, leading to an abscess. Percutaneous aspiration of the abscess was performed, and approximately 1.5 ml of purulent discharge was drained. Antibiotics were continued, and the symptoms improved. The patient was discharged on postoperative day 9. Although there are reports of abscess formation in a hernia sac after panperitonitis and surgery for perforated appendicitis, most occurred in elderly patients. As seen in the present case, young people can also develop a hernia sac abscess after intraperitoneal infection, thus emphasizing the need to remain alert during the postoperative course.
