Abstract

Fifteen patients with nonparasitic hepatic cysts underwent surgery to relieve abdominal complaints, at the First Surgical Department, Tokyo University Hospital between 1966 and 1989. Total removal of the cyst was carried out in 14 of the patients, while puncture and aspiration only were performed in the other patient in whom a cyst had ruptured spontaneously, after which hemoperitoneum was observed at emergency laparotomy. The size of the cysts varied from 7-19 cm with a mean of 12.4 cm. Histological study revealed a congenital cyst in 14 patients and a cystadenoma in one. The epithelium lining of the internal surface of the congenital cysts was highly atrophic and desolated and often disappeared. Examination of the cyst fluid revealed the same concentration of electrolytes as in the serum. Hepatic enzyme levels were usually lower than in the serum, but lactic dehydrogenase and aminotransferase levels were elevated in a few cases. Tumor marker levels of the cyst fluid were higher than those in the serum in four of five patients examined.

肝脏非寄生囊肿的手术经验——囊肿液的特征和成分。
1966年至1989年间,在东京大学医院第一外科,15例非寄生性肝囊肿患者接受了手术以缓解腹部不适。14例患者全部切除囊肿,另1例囊肿自发破裂患者仅穿刺抽吸,术后急诊开腹观察腹腔积血。囊肿大小7- 19cm不等,平均12.4 cm。组织学研究显示先天性囊肿14例,囊腺瘤1例。先天性囊肿内表面上皮内层高度萎缩、脱落,常消失。囊肿液检查显示电解质浓度与血清相同。肝酶水平通常低于血清水平,但少数病例乳酸脱氢酶和转氨酶水平升高。5例患者中有4例囊肿液肿瘤标志物水平高于血清。
