A good knowledge of acquired morphologic changes and congenital anomalies requires precise understanding of pathologic conditions of the visceral organs. The aim of the present study was to systematically investigate the types and frequencies of laparoscopically observed congenital anomalies of the liver.
We studied congenital anomalies observed laparoscopically in 1802 consecutive patients who underwent laparoscopy from 1981 to 1994.
Congenital anomalies observed laparoscopically were as follows: ape's (monkey's) fissure (6.8%), fissure formation with anomalous lobation (4.3%), left deviation of the round ligament (3.6%), high insertion of the round ligament (2.8%), ectopic liver and accessory lobe of the liver (0.7%), lobar fusion (0.5%), partial defect of the falciform ligament (0.3%), and situs inversus totalis (0.1%). None of these anomalies except situs inversus totalis were diagnosed by imaging techniques other than laparoscopy.
Congenital anomalies of the liver are unexpectedly frequent (19.3% of patients) at laparoscopy, which seems to be the most useful method for finding such anomalies.
要充分了解后天形态学改变和先天性异常，需要精确掌握内脏器官的病理状况。本研究的目的是系统地调查腹腔镜观察到的肝脏先天性异常的类型和发生率。
我们研究了1981年至1994年间连续接受腹腔镜检查的1802例患者中通过腹腔镜观察到的先天性异常。
腹腔镜观察到的先天性异常如下：猿裂（6.8%）、伴有异常分叶的裂形成（4.3%）、圆韧带左偏（3.6%）、圆韧带高位附着（2.8%）、异位肝和肝副叶（0.7%）、叶融合（0.5%）、镰状韧带部分缺损（0.3%）和全内脏转位（0.1%）。除全内脏转位外，这些异常均未通过腹腔镜以外的成像技术诊断出来。
腹腔镜检查时肝脏先天性异常的发生率出乎意料地高（占患者的19.3%），这似乎是发现此类异常最有用的方法。
