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 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.
【Abstract】Objective To study the regulatory ability of peroxisome proliferatoractivated receptor γ(PPARγ) ligands to the inflammatory response in human gallbladder epithelial cells. Methods Culture human gallbladder epithelial cells and identify them . Cells were treated for 24 hours with 0, 10 μmol/L, 20 μmol/L, 30 μmol/L, 50 μmol/L and 100 μmol/L of Ciglitazone during cellular growth peak(5th day), then stimulated them with hIL-1β 5 ng/ml for 2 hours and measured the concentration of IL-6、IL-8 and TNF-α in cellular supernatants by riadioimmunoassay. Results Contrasted with control group, the expression of IL-6 and IL-8 in each test group were inhibited （P＜0.001）. The IL-6 and IL-8 levels were gradually dropped and corelated with the dosage of Cigtitazone, and manifested dosagedependence (P＜0.001). The concentration of TNF-α could not be measured. Conclusion PPARγ ligands can inhibit the expression of IL-6 and IL-8 in human gallbladder epithelial cells and probably produce effect in the regulation of cholecystic inflammation.
Objective To discuss the therapeutic effect and safety of laparoscopic cholecystectomy plus laparoscopiccommon bile duct exploration （LC＋LCBDE） and endoscopic retrograde cholangiopancreatography/endoscopic sphincte-rotomy plus LC （ERCP/EST＋LC） for cholecystolithiasis with choledocholithiasis patients with obstructive jaundice. Methods The clinical data of cholecystolithiasis with choledocholithiasis patients with obstructive jaundice from January2011 to June 2012 were analyzed retrospectively. During this period， 48 patients were treated by LC＋LCBDE （LC＋LCBDE group）， and 76 patients by ERCP/EST＋LC （ERCP/EST＋LC group）. Results ①There were no statistical significances in the age， gender， preoperative total bilirubin， alanine aminotransferase， number and maximum diameter of common bile duct stone， and internal diameter of common bile duct in two groups （P＞0.05）. ②No perioperative mortality occurred and no significant differences were observed in terms of stone clearance from the common bile duct， postoperative morbidity， and conversion to open surgery in two groups （P＞0.05）. However， the operative time and post-operative hospital stay in the LC＋LCBDE group were shorter than those in the ERCP/EST＋LC group （P＜0.05）. In addi-tion， the costs of surgical procedure and hospitalization charges in the LC＋LCBDE group were less than those in the ERCP/EST＋LC group （P＜0.05）. Conclusions Both LC＋LCBDE and ERCP/EST＋LC are safe and effective therapies forcholecystolithiasis with choledocholithiasis patients with obstructive jaundice. However， LC＋LCBDE is better for pati-ents’ recovery and cost effective. Especially for patients with common bile duct＞1.0cm in diameter or with multiple common bile duct stones， LC＋LCBDE is the best choice. To sum up， the choice of minimally invasive treatment must be individualized according to the patient’s condition and the availability of local resources.
ObjectiveTo explore the suitable method for isolation and maintenance of primary cultures of human gallbladder epithelial cells (GECs) for establishing the basis of research works in physiological function of gallbladder and its related diseases.MethodsGECs were isolated with collagenase type Ⅳ and blunt separation.The dishes were coated with fibronectin, laminin and polyDlysine respectively.Additional 10 ng/ml epidermal growth factor was added to DMEM medium containing 20% fetal calf serum.The cells were studied under light and electron microscope to determine their shape and distribution.ResultsEach gallbladder yielded approximately (1-5)×107columnar epithelial cells,greater than 95% of which were viable by trypan blue exclusion.The cells grew vigorously within one week which was flat and multangular in shape. CK19 expressed positive.Electron microscope showed typical gallbladder epithelia with microvilli,tight junctions and mucus droplets.ConclusionCombination of collagenase type Ⅳ，mechanical blunt separation and twostep attachment is of great benefit for separating and harvesting GEC.Fibronectin coated culture dish and DMEM medium containing 20% calf serum and 10 ng/ml hEGF is of great benefit for culturing gallbladder epithelial cells.
