规则性肝段切除术治疗肝内胆管结石病

目的 总结采用肝段切除术治疗肝内胆管结石病的经验。方法 回顾性分析1975年1月至1998年12月间采用肝段切除术治疗514例肝内胆管结石的临床资料及远期疗效。结果 肝内胆管结石的分布：左外叶64例、左肝叶176例、右前叶10例、右后叶24例、右肝叶31例、双侧肝叶209例。合并症：合并有显著肝段或肝叶萎缩者280例，肝脓肿17例，胆瘘7例，胆管癌8例。265例有1-5次胆道手术史。手术方法：根据肝内结石的分布决定肝段或联合肝段切除的范围，其中S2－3切除284例、切除98例、切除26例、切除37例、双侧肝叶部分切除23例。附加术式包括经肝门胆管切开取石217例，经肝实质肝内胆管切开取石11例，胆管空肠Roux-en-Y吻合296例。术后并发症有胆漏15例（2.9%）、膈下感染23例(4.5%)、腹腔脓肿2例（0.4%）和肝衰3例（0.6%）等。11例（2.1%）术后死于肝衰竭。随访10个月到25年，75.9%症状消失，14.5%偶而有轻度胆管炎发作，9.6%仍反复发作严重胆道感染。49例手术效果差的主要原因是肝脏切除范围不够兖分而遗留病变的肝胆管。结论 规则性肝叶切除术是清除病灶的最有效手段。

Anatomic hepatectomy for the treatment of hepatolithiasis

Objective To evaluate the long term results of regular hepatic resection for hepatolithiasis.Methods Five hundred and fourteen patients with hepatolithiasis underwent hepatic resection from Jan. 1975 to Dec. 1998 in Southwest Hospital. The indications included stones confined to one segment or one lobe of the liver, significant atrophy of the portion of the liver harboring the stones from repeated episodes of obstruction and infection, multiple strictures of the ducts in the affected portion of the liver. Resection of S 2 and S 3 was performed in 284 patients, S 2, S 3 and S 4 in 98 patients, S 6 and S 7 in 26 patients, S 5, S 6, S 7 and S 8 in 37 patients; both of the left and right hepatic lobes were partially resected in 23 patients. Additional biliary procedures including choledochojejunostomy and common bile duct exploration were performed in 296 patients.Results The operative mortality was 2 1%, and the morbidity rate was 8 4%. The majority of complications were biliary fistulas (2 9%), subphrenic infection (4 5%), peritoneal abscesses (0 4%) and liver failure (0 6%). Long term follow up on 436 patients at a median of 9 1 years showed that 75 9% were symptom free, 14 5% had occassional mild attacks of cholangitis, 9 6% had severe cholangitis requiring further surgical intervention.Conclusion Anatomic hepatic resection is the most effective treatment and the therapy of choise to eradicate intrahapatic stone foci in cases of hepatolithiasis .
