INTRODUCTION
True Left-sided gallbladder (LSG) is a rare anatomical variation with a prevalence of 0.3%. Mainly discovered during the operation, its surgical approach in the laparoscopic setting may be challenging even for an experienced surgeon.
PRESENTATION OF CASE
LSG was unexpectedly discovered in a young man during laparoscopic cholecystectomy. There were no pre-operative indications of this sinistroposition. The laparoscopic cholecystectomy was performed with minor surgical modifications and it was uneventful. A meticulous review of recent literature about LSGs was conducted as well.
DISCUSSION
LSG is a scarce anatomical aberration that is difficultly identified pre-operatively. Surgeons should be aware of this aberration and of its accompanying anatomical variations in order to perform a safe laparoscopic cholecystectomy.
CONCLUSION
Surgeons, by placing the patient to left-side up position, are able to expose the Calot's triangle and possible accompanying anatomical anomalies and thus perform a safe laparoscopic cholecystectomy without difficult surgical modifications.
引言
真性左侧胆囊（LSG）是一种罕见的解剖变异，发生率为0.3%。主要在手术中发现，即使对于经验丰富的外科医生而言，其腹腔镜手术入路也可能具有挑战性。
病例介绍
在一名年轻男性行腹腔镜胆囊切除术时意外发现LSG。术前并无此异位的迹象。腹腔镜胆囊切除术在进行了微小的手术改良后顺利完成。同时对近期关于LSG的文献进行了细致回顾。
讨论
LSG是一种罕见的解剖变异，术前很难识别。外科医生应了解这种变异及其伴随的解剖学变化，以便实施安全的腹腔镜胆囊切除术。
结论
外科医生通过将患者置于左侧卧位，能够暴露胆囊三角及可能伴随的解剖异常，从而在无需进行困难的手术改良的情况下实施安全的腹腔镜胆囊切除术。
