Abstract

Background: Gallbladder adenocarcinoma is the most common malignant tumor of the biliary tract. Most of gall bladder cancers are detected incidentally only after pathological examination of the excised surgical specimens. In this study we investigated the characteristics of incidental gallbladder cancers in our center.  Material & methods: We retrospectively reviewed all of the cholecystectomy specimens in sent for histopathology following laparoscopic cholecystectomy in the study period from January 2015 to October 2019. Clinicopathological characteristics were extracted from the patients' clinical charts, which included symptoms, radiological findings, laboratory data, and surgical procedures as well as outcome. Results: We identified 6 cases of incidental gall bladder cancer, consisting of 4 women and 2 men ranging in age from 28 to 77 years (mean age 60.5 after pathological study of 1530 resected gall bladders. Out of the 6 cases, 1 case was carcinoma in situ of gall bladder, 1 was T1b  and other 4 cases were T2 carcinoma. Conclusions: The rate of incidental gallbladder carcinoma in our study was 0.39%. This lower incidence could in part be due to increasing use of routine laparoscopic cholecystectomy for symptomatic gallbladder. This strategy of increased early intervention further adds to the advantage of higher chances of gallbladder cancer detection in early stages, and thus better prognosis.
腹腔镜胆囊切除术后偶发胆囊癌:单中心研究
背景:胆囊腺癌是胆道最常见的恶性肿瘤。大多数胆囊癌是在切除手术标本的病理检查后偶然发现的。在本研究中,我们调查了本中心偶发胆囊癌的特点。材料与方法:回顾性分析2015年1月至2019年10月研究期间腹腔镜胆囊切除术后送往组织病理学检查的所有胆囊切除术标本。从患者的临床图表中提取临床病理特征,包括症状、放射学表现、实验室数据、手术过程和结果。结果:6例偶发性胆囊癌,女4例,男2例,年龄28 ~ 77岁(平均年龄60.5岁),共切除胆囊1530例。6例中胆囊原位癌1例,T1b癌1例,T2癌4例。结论:本组胆囊癌发生率为0.39%。这种较低的发生率可能部分是由于常规腹腔镜胆囊切除术治疗症状性胆囊的使用增加。这种增加早期干预的策略进一步增加了早期发现胆囊癌的更高机会,从而获得更好的预后。
