I prospectively studied 100 patients to see whether "incidental appendectomy" with cholecystectomy affects wound infection rate. Randomization resulted in groups similar in age, habitus, and sex. Forty-seven patients had appendectomy. The most frequent gallbladder disease was chronic calculous cholecystitis. Positive cultures were obtained from 11% of gallbladders. The mean age of patients with gallbladder bacteria was 14.5 years older than that of the series. True pathologic changes were seen in 6% of appendices. Average operative time was extended six minutes by appendectomy. Length of postoperative hospital stay was unchanged by the addition of appendectomy. There were no infections in the patients without appendectomy and one (2%) in the group with appendectomy. The total 1% infection rate is considerably below most reported rates. There was no difference in infection rate between groups with and without appendectomy (P = .47). Unless the procedure is technically difficult, appendectomy with elective cholecystectomy does not increase the chance of infection.
我前瞻性地研究了100例患者，以观察胆囊切除术时行“附带阑尾切除术”是否会影响伤口感染率。随机分组后，两组患者在年龄、体型和性别方面相似。47例患者接受了阑尾切除术。最常见的胆囊疾病是慢性结石性胆囊炎。11%的胆囊培养结果呈阳性。胆囊有细菌感染的患者平均年龄比该系列患者大14.5岁。6%的阑尾可见真正的病理改变。阑尾切除术使平均手术时间延长了6分钟。增加阑尾切除术后，术后住院时间未改变。未行阑尾切除术的患者无感染，而行阑尾切除术的组中有1例（2%）感染。总的1%感染率远低于大多数报告的感染率。行阑尾切除术组和未行阑尾切除术组之间的感染率无差异（P = 0.47）。除非手术操作技术上有困难，择期胆囊切除术时行阑尾切除术不会增加感染几率。
