The purpose of this article is to describe the diagnostic pitfalls caused by dropped gallstones left in situ after laparoscopic cholecystectomy.
Dropped gallstones may rarely become symptomatic, causing recurrent abscesses. Diagnosis is challenging due to unusual clinical presentations, myriad locations, and radiologically occult calculi. Even asymptomatic dropped gallstones may cause diagnostic confusion by masquerading as intraperitoneal neoplastic deposits. Radiologists should be aware of techniques for identifying and retrieving dropped gallstones and be wary of their complications and imitations in patients who have undergone laparoscopic cholecystectomy.
本文旨在描述腹腔镜胆囊切除术后遗留的胆囊结石脱落所导致的诊断陷阱。
脱落的胆囊结石可能很少出现症状，但会导致复发性脓肿。由于临床表现不典型、结石位置多样且影像学上隐匿，因此诊断具有挑战性。即使无症状的脱落胆囊结石也可能通过伪装成腹腔内肿瘤沉积而导致诊断混淆。放射科医生应熟悉识别和取出脱落胆囊结石的技术，并警惕在接受腹腔镜胆囊切除术的患者中这些技术的并发症和局限性。
