摘要:When acute appendicitis is present and lately treated, further complications will occur against patients. This case report describes an unusual presentation of acute appendicitis in a young patient and demonstrates a unique late compli- cation of perforated appendicitis. A 15 year old female acute appendicitis patient had lapara- tomy accompanied systemic inflammatory re- sponse syndrome (SIRS) symptoms. After treatment of 6 days in the intensive care unit (ICU), the patient was healed. We emphasize the importance of early treatment for acute appen- dicitis and septic complications.
