Abstract
We report herein on the case of a 32-year old female in whom situs inversus had been recognized since childhood. She came to the emergency room complaining of abdominal pain since the previous day. At the time of initial diagnosis, WBC and CRP were elevated and tumefaction, which was assumed to be associated with the appendix, was observed in the left lower abdominal quadrant on abdominal CT imaging. Acute appendicitis with situs inversus totalis was diagnosed and the patient was admitted to the hospital for conservative treatment. Improvement in the symptoms was observed, but following the patients request, a single incision laparoscopic appendectomy was carried out on the fourth day. Three days after surgery, the patient was discharged from the hospital with satisfactory progress. Single incision laparoscopic appendectomy is considered to allow intra─abdominal observation over a wide range, and the relative position of each organ could be easily understood. This method is considered to be safe and more cosmetic for acute appendicitis patients with situs inversus. The patient was discharged from the hospital with satisfactory progress. This method is considered to be safe and to produce better cosmetic results for acute appendicitis patients with situs inversus.
