An aberrant biliary duct of segment 5 (B5) is a rare anomaly of the biliary tract. All anatomical anomalies of the biliary tract are risk factors for bile duct injury during surgery. We report a case of cholelithiasis with an aberrant B5 that was detected during a detailed preoperative imaging examination and treated with laparoscopic cholecystectomy.
A 69-year-old woman was admitted to the emergency room of our hospital with abdominal pain. She was diagnosed with cholelithiasis, and an aberrant B5 branching off the hepatic duct was suggested during preoperative imaging. Laparoscopic cholecystectomy was performed at our surgical department. There were no intra- or postoperative complications, and the patient was discharged on the fourth day after surgery.
Laparoscopic cholecystectomy can be safely performed without intra- or postoperative complications in patients with cholelithiasis and an aberrant B5 if it is accurately diagnosed preoperatively.
第5段胆管（B5）异常是一种罕见的胆道异常。胆道的所有解剖异常都是手术中胆管损伤的危险因素。我们报告一例在详细的术前影像学检查中发现的伴有B5异常的胆结石病例，并通过腹腔镜胆囊切除术进行治疗。
一名69岁女性因腹痛入住我院急诊室。她被诊断为胆结石，术前影像学检查提示有一条从肝管分支出来的异常B5。我院外科进行了腹腔镜胆囊切除术。术中及术后均无并发症，患者术后第四天出院。
对于患有胆结石且伴有异常B5的患者，如果术前能准确诊断，腹腔镜胆囊切除术可以安全实施，术中及术后均无并发症。
