Oxidized regenerated cellulose (ORC) is a bioabsorbable surgical hemostatic. We present the first prospective case series of circumscribed mass occurrence after using ORC in laparoscopic cholecystectomy.
Tabotamp (Ethicon, Inc., Somerville, NJ) in the form of tightly woven knitted patches was used to achieve hemostasis in 83 patients submitted to LC.
A subhepatic mass was detected in five patients and radiologic characteristics were described. Abdominal contrast enhanced CT showed a heterogeneous soft-tissue mass. NMR was performed in one patient and showed a T2-weighted hyperintense mass.
ORC retention after surgery is not uncommon at long-term follow-up. The radiologic characteristics of a suspected ORC retention mass can differentiate it from a neoplastic lesion, so that surgery can be avoided.
氧化再生纤维素（ORC）是一种可生物吸收的手术止血材料。我们展示了首例在腹腔镜胆囊切除术中使用ORC后出现局限性肿块的前瞻性病例系列。
采用紧密编织针织片形式的Tabotamp（Ethicon公司，新泽西州萨默维尔）对83例行LC的患者进行止血。
5例患者检测到肝下肿块，并描述了其影像学特征。腹部增强CT显示为不均匀软组织肿块。对1例患者进行了核磁共振检查，显示为T2加权高信号肿块。
长期随访发现术后ORC残留并不少见。疑似ORC残留肿块的影像学特征可将其与肿瘤性病变区分开来，从而避免手术。
