THE LONG TERM RESULTS OF BILIARY RECONSTRUCTION IN CHILDREN

Twenty five children with congenital biliary dilatation were treated with hepatico-jejuno-duodenostomy following excision of choledochal cysts between 1983 and 1985. The age ranged from two months to eleven years. The last follow-up ranged from 6-9 years (mean 7.5 years). All patients were free of jaundice with normal growth and development and none had peptic ulcer. The results from the last follow-up was better than that of the first one. This procedure was safe, effective and physiologically appealing.

目的 了解肝部分切除治疗肝内胆管结石的效果。方法回顾性分析1984年3月至1997年8月对95例肝内胆管结石施行肝部分切除，并辅以狭窄胆管切开整形及胆肠吻合等手术的治疗情况。结果 临床疗效优良者达93.7%，术后残留结石10例，残石率为10.5%。结论 肝部分切除治疗肝内胆管结石是目前较理想有效的手术方式。

Angiological Studies and the Progress of Hepatobiliary Surgery

凡是涉及一个脏器基本结构的研究，不论是大体的、显微镜的、分子的、基因水平或功能状态的研究，都属于临床外科中的基础研究范畴。解剖学研究虽然是外科临床基础研究中最古老的项目，但是随着新科技和临床外科学的发展，又从未间断地添加新的研究内容。例如当前的可视化人体的研究便是个突出的例子。肝、胆管血循环的研究在当代的胆道外科学和移植外科学中占有重要的位置, 而上世纪50年代初期的肝内管道解剖学研究，奠定了现代肝脏外科的基础。

Extended Resections for Hilar Cholangiocarcinoma and Therapeutic Evaluation

经皮经肝胆道镜碎石取石术治疗胆肠吻合术后肝胆管结石病

目的探讨经皮经肝胆道镜碎石取石术（PTCSL）必要时联合球囊扩张治疗胆肠吻合术后肝胆管结石病的可行性及安全性。方法重庆医科大学附属第二医院 2015 年 12 月至 2020 年 12 月期间共有 54 例胆肠吻合术后肝胆管结石病患者接受 PTCSL 必要时联合球囊扩张治疗（符合纳入标准）。回顾性收集患者的一般资料、手术情况、术后情况以及术后随访资料。结果54 例患者中有 52 例（96.3%）行 PTCSL 治疗成功，2 例因为胆肠吻合口完全闭塞而失败。术中出血量的中位数为 55 mL（15～520 mL）；取净结石 48 例（88.9%），结石残留 6 例（11.1%）。术后并发症发生率为 27.8%（15/54），无围手术期死亡患者。取净结石的 48 例患者获随访，中位随访时间 33 个月（2～60 个月），有 10 例结石复发，复发率为 20.8%（10/48）。结论PTCSL 必要时联合球囊扩张治疗胆肠吻合术后肝胆管结石病具有良好的安全性和可行性，但是术后需要注意预防结石复发。

Attach Importance to Surgical Therapy for Hilar Cholangiocarcinoma

Invasion of Major Intrahepatic Ductal Structures by Hepatocellular Carcinoma: Multi-Detector-Row Spiral CT Manifestations

【Abstract】Objective To investigate the imaging features of malignant invasion of major intrahepatic ductal structures (the portal and hepatic venous vasculature, the bilie duct) by primary hepatocellular carcinoma (HCC) using multidetector-row spiral CT (MDCT). Methods We retrospectively analyzed 68 documented HCC patients with tumorous invasion of the major intrahepatic ductal structures who had undergone contrast-enhanced dual-phase MDCT scanning of the upper abdomen.The morphological changes of the portal and hepatic venous vasculature, the bile duct, and the liver parenchyma at both the hepatic arterial phase and portal venous phase images were carefully observed and recorded. Results Among the 68 patients, 47 patients had malignant invasion of the intrahepatic portal venous vessels with secondary tumor thrombus formation; 12 patients had tumor involvement of the hepatic veins and intraheptic segment of the inferior vena cava; Tumor invasion of the bile duct was seen in 9 patents. The direct CT signs of tumor invasion of intrahepatic venous vessels included: ①dilatation or enlargement of the involved vein with intraluminal softtissue “filling defect”； ②enhancement of the tumor thrombus at hepatic arterial phase, the so-called “venous arterialization” phenomenon. The indirect CT signs included: ①arterial-venous shunt, ②early and heterogeneous enhancement of the hepatic parenchyma adjacent to HCC focus, ③cavernous transformation of the portal vein. The CT signs suggesting tumor invasion of the bile duct included: ①dilation of the bile ducts near or proximal to HCC lesion, ②soft-tissue nodule or mass inside the bile ducts. Conclusion Invasion of major intrahepatic ductal structures by HCC will present corresponding CT imaging features. Contrast-enhanced MDCT dualphase scanning combined with appropriate image postprocessing techniques can better evaluate the malignant invasion of major intrahepatic ductal structures.

Present Status and Prospection of Surgical Treatment for Cholangiocarcinoma

Application of enhanced recovery after surgery in perioperative treatment of hepatolithiasis: current status and prospect

Objective To summarize contents of enhanced recovery after surgery (ERAS) and understand it’s status and prospect in application of patients with hepatolithiasis. Methods The descriptions of ERAS in recent years and applications in hepatolithiasis were reviewed. Results The ERAS programme mainly included the preoperative managements, such as the education, nutrition management, and gastrointestinal tract management; the intraoperative managements, such as the minimally invasive surgery, reasonable choice of anesthesia, infusion volume management, and maintenance of body temperature, analgesia, and preventing postoperative nausea and vomiting medication selection; the postoperative early feeding, early exercise, early extubation, multimodal analgesia, T tube management, reasonable discharge standard and follow-up management. Although the ERAS was rarely reported in patients with hepatolithiasis, it had some advantages of promoting recovery and improving patient satisfaction, and it was still effective and safe. Conclusions Application of ERAS concept in patients with hepatolithiasis has achieved precision management and individualized treatment during perioperative period. It could achieve a good short-term therapeutic effect and optimize medical management model. However, there are still some problems at the present stage in implementation and promotion of patients with hepatolithiasis, such as lacks of criteria and specifications, evidence-based medicine. It is needed to further strengthen communication and collaboration among multiple disciplinary teams so as to further improve ERAS programme and popularize it.
