Abstract Background and Aims: Hem-o-lok clips are widely used for cystic duct and vascular closure during laparoscopic cholecystectomy (LC). Although rare, postoperative clip migration may occur, with the clip entering the common bile duct (CBD) and acting as a foreign body. Its imaging features often mimic choledocholithiasis, posing diagnostic and therapeutic challenges. Clinical awareness of this late complication remains insufficient. This study aims to summarize the clinical characteristics and management strategies through a case analysis and literature review.
Methods: The clinical data of a 29-year-old woman admitted in October 2025, four years after LC, were retrospectively reviewed. She was diagnosed with suspected CBD stones during routine examination one year prior to admission. Preoperative imaging revealed multiple filling defects in the CBD. The patient declined endoscopic retrograde cholangiopancreatography and underwent laparoscopic common bile duct exploration (LCBDE). Intraoperative findings, imaging characteristics, diagnostic process, and management were analyzed in conjunction with relevant literature.
Results: Preoperative imaging suggested multiple CBD stones. During LCBDE, three migrated Hem-o-lok clips were identified and removed from the middle and lower CBD under choledochoscopic guidance. No pigment stones were observed around the clips. The final diagnosis was foreign bodies in the CBD (Hem-o-lok clips). A T-tube was placed for drainage. The patient recovered uneventfully and was discharged. Two months later, T-tube cholangiography confirmed a patent CBD without residual stones or foreign bodies, and the tube was removed successfully.

胆石症是一种常见的消化系统疾病,约10%~15%的成年人受其影响[1]。该病特征为胆汁成分硬化形成结石,常引发胆囊炎、胆管炎及胰腺炎等严重并发症。当前的治疗方案包括药物、内镜及外科手术等,但存在侵入性、疗程长或复发风险等局限性[2]。对于合并胆总管结石的患者,临床主要采用两种策略:腹腔镜胆囊切除术(laparoscopic cholecystectomy,LC)同期行腹腔镜胆总管探查术(laparoscopic common bile duct exploration,LCBDE),或先行内镜下逆行胰胆管造影(endoscopic retrograde cholangiopancreatography,ERCP)/内镜括约肌切开术(endoscopic sphincterotomy,EST)取石后再行LC[
1 病历资料
患者 女,29岁。因“体检发现胆总管结石1年余”于2025年10月12日入院。患者1年前孕检时超声首次发现胆总管结石,未予治疗,此后间断出现劳累后背部隐痛,无发热、寒战、黄疸等胆管炎典型症状。既往史值得注意的是,患者4年前因胆囊结石于外院接受LC。入院查体:生命体征平稳,腹平软,腹部可见3处长约1 cm愈合瘢痕,无压痛、反跳痛,未触及包块。实验室检查提示总胆红素23.3 μmol/L,直接胆红素9.2 μmol/L,丙氨酸氨基转移酶32 U/L,天门冬氨酸氨基转移酶23 U/L,感染指标未见明显异常。初步影像学评估:腹部超声、计算机断层扫描(CT)及磁共振胰胆管成像(MRCP)均明确提示胆囊术后缺如,值得注意的是,原胆囊三角区未见血管夹残留影。胆总管轻度扩张(直径约0.9 cm),其内见多发结节样低信号充盈缺损(图1)。初步诊断为胆总管结石、胆总管扩张、胆囊切除术后。
