Objective To investigate the prevention and treatment strategy of bile duct injury (BDI) in laparoscopic cholecystectomy (LC). MethodsLatest progress was reviewed based on recent documents and the experience on BDI in LC in our department. ResultsWith the popularity of LC, BDI in LC is increasing. The reasons include illegibility and variability of local anatomy in gallbladder trigone,injury caused by galvanothermy, as well as operator’s overconfidence. In order to prevent BDI, we should apply more blunt dissection, not to use electrocogulation if possible and to study local anatomy and its variance clearly. The common bile duct and common hepatic duct should be clearly identified. Intraoperative cholangiography, laparoscopic ultrasonography and hepatobiliary scintigraphy are selections as necessary.The treatment of BDI depends on the type of BDI and its site and local condition.The treatment includes end to end anastomosis, repairing the defect, choledochoduodenostomy, RouxenY choledochojejunostomy and so on. T tube should be maintained in place for more than half a year after operation.Conclusion The key to improve the prognosis of BDI is prevention and treatment in proper time and in correct way.
Objective To study the advances in the relationship between the number of infiltrating dendritic cells and the postoperative prognosis of digestive malignant tumor. MethodsThe literature in recent years on the relationship between the number of infiltrating dendritic cells and the postoperative prognosis of digestive malignant tumor was reviewed.ResultsThe number of infiltrating dendritic cells among esophageal cancer,and gastric carcinoma,colonic cancer and pancreatic cancer was associated with a better prognosis.Conclusion The population density of dendritic cells among the malignant tissue could be regarded as an independent indicator in estimating the postoperative prognosis of malignant tumor.

目的:探讨腹腔镜胆囊切除术（laparoscopic cholecystectomy，LC）致胆管损伤的原因、预防措施和经验教训。方法:分析2007年8月～2008年8月期间我院胆道外科收治的3例胆管严重损伤病例资料。结果:3例LC术致胆管严重损伤的患者均发生肝门部胆管狭窄，并均在肝门胆管成形后行胆管空肠Roux-en-Y吻合术，吻合口直径2.0～3.0 cm。术后患者恢复良好，均顺利出院，住院时间为10～15天。随访1～6个月，1例于术后2月出现肝区隐痛，口服消炎药可控制，其余未见异常不适。结论:术中仔细辩清肝总管、胆总管与胆囊管的三者关系是预防LC术胆管损伤的关键。胆管空肠Roux-en-Y吻合术是处理胆管损伤的重要手术方式。LC术时，胆道外科医生思想上要高度重视，不可盲目追求速度。
Objective To study the clinical diagnosis and treatment of juxtapapillary duodenal diverticula with biliary deseases.Methods Eighteen duodenal diverticulum treated in our department in recent 5 years were retrospectivly analyzed, especially investigated the postcholecystectomy cases whose symptoms were continuing existence after operatoins. Articles about the surgical treatment were reviewed. Results The total of 18 duodenal diverticulum with 17 cases of juxtapapillary duodenal diverticulum were included in this study. The ages of 12 cases were over 50 years old. Sixteen cases(88.89%) presented biliary stones. Seven cases once had performed cholecystectomy or cholecystectomy plus choledochotomy,but symptoms persisted after operations. The duodenal diverticulum were found by endoscopic retrograde cholangiopancreatography (ERCP) and hypotonic duodenography. Sixteen patients underwent surgical treatment with good effect. Conclusion The juxtapapillary duodenal diveticula has the close relationship with biliary stones. ERCP and hypotonic duodenogrphy are the most reliable methods to get the correct diagnosis. In case of recurrent common bile duct stones after operations or persisting billiary symptoms after cholecystectomy, the coexistence of juxtapapillary duodenal diverticulum should be ruled out. The surgical treatment is only considered for the duodenal diverticulum with complication.
Objective To investigate the feasibility of laparoscopic cholecystectomy through the transumbilical approach. MethodsThe clinical data of 18 patients underwent endoscopic cholecystectomy through only one transumbilical incision at West China Hospital were retrospectively analyzed. Results All of the operations were successfully completed without conversion to routine laparoscopic surgery or open surgery. The operation time was 40-130 （58±10） min. There was no intraoperative complication. The patients did well postoperatively and were discharged 1 day after operation. There was no postoperative complications and without visible abdominal scar on 1 month follow-up. Conclusions Laparoscopic cholecystectomy through the transumbilical approach is technically feasible and safe. But this technique is difficult, the patients should be selected carefully.
【Abstract】Objective To analysis the clinical characteristics, pathogenesis, diagnosis and treatment of acute acalculous cholecystitis.Methods Seventy-nine cases of acute acalculous cholecystitis from January 1996 to January 2003 were retrospectively reviewed.Results Of those 79 cases, 13 cases were treated nonoperatively and 66 cases were treated operatively. Twentythree cases were suppurative, 43 cases were gangrenous with perforation in 18 cases，which were proved by postoperative pathology. Seventysix cases were cured and 3 cases were dead. Conclusion Keeping vigilant alert, observing dynamically as well as appropriate operative intervention are effective to improve the prognosis of acute acalculous cholecystitis.
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.

Objective To investigate the cell compatibility of the porcine acellular lumens matrix substituting bile duct and evaluate the method to guide the clinical application of the porcine lumens scaffold. Methods Porcine bile duct and ureter were treated using detergent sodium dodecylsulphate (SDS) and 1% Triton X-100 to prepare the acellular lumens matrix. The toxic effects of different concentrations of acellular lumens matrix extract were tested by MTT to assess the proliferation of human scarfskin fibroblasts (HSF). The cytotoxicity of the target biomaterial was graded according to the national standards. The growth manner of the human intrahepatic bile duct endothelial cells (HIBDCs) seeded on the acellular lumens matrix was studied after 20 d under scanning electron microscopy.Results Acellular lumens matrix was completely devoid of cellular and nuclear material while maintaining the integrity of extracellular collagenous matrix. The cytotoxicity score of the matrix was in grade 0－1, which meant the biomaterial had no cytotoxicity. The microscopy showed the seeded HIBDCs had the potentials of spread and proliferation on the matrix, but there were few cells infiltrating into the acellular lumens matrix. Conclusions Porcine acellular lumens matrix is a natural non-toxic xenogenic lumens substitute with good cell affinity, but the time of adherence is long, so further endeavors are needed to improve the progress of adherence.
