Subtotal hepatectomy with preservation of caudate lobe for extensive hepatolithiasis with atrophy of left and right hepatic lobe and obvious hypertrophy of caudate lobe:a case report

目的探讨广泛肝内胆管结石合并左右肝叶萎缩而尾状叶明显肥大的患者行保留尾状叶次全肝切除术的可行性和安全性。方法回顾性分析四川大学华西医院2020年2月收治的1例肝内胆管结石患者的临床病理资料。结果患者左右肝叶结石伴左右肝叶明显萎缩而尾状叶明显肥大。患者术前一般情况良好,心、肺和肾功能正常,肝功能Child-Pugh A级,肝脏储备功能良好。患者体表面积为1.745 m2,标准肝体积为1 235 mL,CT图像三维重建评估肝尾状叶体积为735 mL,占标准肝体积59.5%,经评估患者能耐受手术。患者成功经历保留尾状叶次全肝切除术,术后肝功能恢复良好,术后第2天拔除胃管,术后第5天拔除腹腔引流管,术后第6天出院。术后病理诊断:肝内胆管扩张伴胆管结石,胆管周围大量炎细胞浸润,门管区纤维组织增生、小胆管增生、炎细胞浸润,病变符合肝内胆管结石改变。结论通过对本病例的分析结果看,对于广泛肝内胆管结石合并左右肝明显萎缩而尾状叶明显肥大的患者,保留尾状叶次全肝切除术是安全、可行的。

Objective To investigate the feasibility and safety of subtotal hepatectomy with preservation of caudate lobe for extensive hepatolithiasis with atrophy of left and right hepatic lobe and obvious hypertrophy of caudate lobe. Method The clinicopathologic data of patient with hepatolithiasis whose left and right hepatic lobe atrophied and caudate lobe obviously hypertrophied admitted to the West China Hospital of Sichuan University in February 2020 were analyzed retrospectively. Results The patient was in good general condition before the operation. The cardiopulmonary and kidney functions were normal. The liver function was Child-Pugh A grade,and the liver reserve function was good.The body surface area of the patient was 1.745 m^2 and the standard liver volume was 1 235 mL. The volume of caudate lobe calculated by the 3D reconstruction of CT image was 735 mL,accounted for 59.5% of the standard liver volume. The patient was evaluated to be able to tolerate the operation. The patient successfully experienced the operation of subtotal hepatectomy with caudate lobe preservation. The postoperative liver function recovered well. The gastric tube was removed on the 4th day after the operation. The peritoneal drainage tube was removed on the 5th day after the operation.The patient was discharged on the 6th day after the operation. The postoperative pathological diagnosis: The intrahepatic bile duct was dilated with stones inside. A large number of inflammatory cell infiltrated around the bile duct. The fibrous tissue hyperplasia,small bile duct hyperplasia and inflammatory cell infiltration were observed in the portal area. The pathological changes were consistent with the changes of hepatolithiasis. Conclusion According to analysis results of this case,subtotal hepatectomy with preservation of caudate lobe is safe and feasible for hepatolithiasis patient with obvious atrophy of left and right hepatic lobe and obvious hypertrophy of caudate lobe.
