Residual or recurrent stones in the common bile duct can pose a difficult diagnostic problem in the symptomatic postcholecystectomy patient. Although incrustation of unabsorbed suture material is the most important cause of stone recurrence in the common bile duct after surgery, hemostatic clips may also (though rarely) provide a nucleus for stone formation. We present two cases in which this occurred. Careful attention to the position and orientation of surgical clips on serial postoperative film studies can be most helpful in diagnosing this rare condition.
胆总管残留结石或复发性结石，对于有症状的胆囊切除术后患者而言，可能会带来诊断难题。尽管未吸收缝线材料的结痂是术后胆总管结石复发的最重要原因，但止血夹也可能（尽管很少见）成为结石形成的核心。我们报告两例发生这种情况的病例。在术后系列影像学检查中仔细留意手术夹的位置和方向，对诊断这种罕见病症会非常有帮助。
