Forty-nine patients had conservative treatment of an appendix mass without interval appendectomy. Five were lost to follow-up within 6 months, and 44 patients were followed for between 6 months and 22 years. In nine patients (20 percent) recurrent appendicitis developed, and six (14 percent) suffered chronic pain not thought to be due to appendicitis. Of the recurrences, 66 percent occurred within 2 years of the initial attack. Barium examination of the cecum was successful in diagnosing two of three additional patients in whom a right iliac fossa mass was not due to appendicitis. The morbidity and expense of routine interval appendectomy was thus eliminated in 80 percent of the patients.
49例阑尾肿块患者接受了保守治疗，未进行间隔期阑尾切除术。5例在6个月内失访，44例随访时间为6个月至22年。9例（20%）发生复发性阑尾炎，6例（14%）患有慢性疼痛，认为并非由阑尾炎引起。在复发患者中，66%发生在初次发作后的2年内。盲肠钡剂检查成功诊断出另外3例右下腹肿块并非由阑尾炎引起的患者中的2例。因此，80%的患者避免了常规间隔期阑尾切除术的发病率和费用。
