目的：探讨急性胆源性胰腺炎(ABP)手术时机和术式的选择。方法：回顾性分析247例急性胆源性胰腺炎的临床资料。 结果：非手术治疗10例，死亡4例；12例急诊手术后发生并发症5例，死亡2例；169 例延期手术术后发生并发症1例，治愈；56例择期手术无并发症发生。结论：以胆道梗阻为主的ABP应急诊手术解除胆道梗阻；胆道无梗阻先采用非手术治疗，胰腺炎控制后，再处理胆道病变。
The quantitative studies of secretory granules andand lysosomes in gallbladder epithelium and gallbladder bile glycoprotein were performed in 20 gallstone patients and 15 gallstone-free subjects. The results showed that the number, the volume density and the total secrectory granules were significantly increased in gallstone patients compared with gallstone-free controls. The gallstone patients had a markedly reduced number,volume destiny and total lysosome area compared with gallstone-free subjects. The glycoprotein concenrtation in gallblader bile was increased up to 21.04±4.92g/L in gallstone paients,as compare with 13.02±5.72g/L(Plt;0.05)in the stone-free controls. The qualitity of secretory granules and lysosomes was directly proprtational to that of bile glycproteins. Evidence and secrectory granules and lysosomes was directly proporional to taht of bile glycoproteins. Evidence and argument are presentded suggesting that gallblader epithelium secrectory granules affect the concentration of bile glycoprotein and lysosomemay be related to the intracellular degradation of secretory granules.

ObjectiveTo summarize clinical experiences of combination of laparoscope,choledochoscope,and balloon nasobiliary exploration (LCBNE) in treatment of cholecystolithiasis combined with choledocholithiasis with small diameter (0.3-0.8 cm) of common bile duct (CBD). MethodsFrom April 2010 to May 2015,there were 43 cases of cholecystolithiasis combined with choledocholithiasis with small diameter of CBD underwent LCBNE,involving choledochotomy,choledochoscopic exploration,electrohydralic lithothipsy,balloon nasobiliary dilatation for removing cholelith,nasobiliary drainage,and the primary closure of incision. ResultsThe procedure was successful in 27 cases of removing the bile duct residual stones through the choledochoscopic procedure,9 cases through the balloon nasobiliary procedure,and 7 cases were converted to endoscopic sphincterotomy for choledocholithasis.No case was converted to open CBD exploration.No case had residual stone.Bile leakage occurred in 1 case,which was cured by peritoneal drainage and nasobiliary drainage.One patient had a slight pancreatitis after operation.One patient had the stenosis of primary suture of CBD incision.Total postoperative complications rate was 7.0%(3/43).No case had perforations of intestine and bile duct,bleeding,severe pancreatitis,and death after operation. ConclusionFrom preliminary results of limited cases in this study,if patients are indicated,combination of LCBNE in treatment of cholecystolithiasis combined with choledocholithiasis with small diameter of CBD is safe and effective.
Objective To investigate the value of indocyanine green fluorescence imaging in common bile duct reexploration. Methods The clinical data of 32 patients who underwent open common bile duct reexploration in the Affiliated Hospital of Southwest Medical University from January 2018 to December 2020 were collected retrospectively. All patients divided into the control group (conventional exploration group, 20 patients) and the fluorescence imaging group (using indocyanine green fluorescence imaging, 12 patients) according to the operational manner. The intraoperative and postoperative results of two groups were analyzed. Results The operative time [(165.2±6.9) min vs. (130.8±5.5) min], the time to find extrahepatic bile duct [(43.9±3.8) min vs. (23.1±4.1) min] and the amount of bleeding [(207.7±7.7) mL vs. (127.5±15.3) mL] in the control group were longer or more than those in the fluorescence imaging group (P<0.05). The incidence of postoperative infection in the control group [7 cases (35.0%) vs. 0 cases (0.0%)] and the length of hospital stay [(10.8±2.8) d vs. (7.1±1.3) d] were higher or longer than those in the fluorescence imaging group (P<0.05). There were no significant difference between the two groups in the incidence of postoperative bile fistula [6 cases (30.0%) vs. 2 cases (16.7%)] and the incidence of residual stones [3 cases (15.0%) vs. 3 cases (25.0%), P＞0.05]. Conclusion Indocyanine green fluorescence imaging appears to be a feasible, expeditious, useful, and effective imaging method while performing reexploration.
Objective To investigate the roles of NF-κB and EGFR in hepatolithiasis associated with intrahepatic cholangiocarcinoma. Methods Ninety cases of liver tissue specimens from hepatectomies performed in the 2nd Affiliated Hospital of Sun Yat-sen University between August 1989 and June 2009 were enrolled in the study. Among them, 33 cases of hepatolithiasis associated with intrahepatic cholangiocarcinoma were considered as observing group, 32 cases of hepatolithiasis as control group, and 25 cases of normal bile duct tissues as normal control group. The SP method of immunohistochemical staining was applied to detect the expressions of NF-κB and EGFR in intrahepatic biliary ducts epithelial cells, and their relations with clinicopathologic factors and the accumulated survival rate of hepatolithiasis associated with intrahepatic cholangiocarcinoma were analyzed. Results Expression rates of NF-κB and EGFR were gradually raised from normal control group, control group to observing group (Plt;0.01). Expression of EGFR in tumor patients was related to histopathologic differentiation grading and the depth of tumor invasion (Plt;0.05), but not to gender, age, or lymph node metastasis (Pgt;0.05)； there were no significant relationships between the expression of NF-κB and factors described above (Pgt;0.05). The survival rate of patients with tumor expressed EGFR was significantly lower than that of patients with tumor non-expressed EGFR (Plt;0.01). Conclusions NF-κB expression is in the early stage during intrahepatic cholangiocarcinoma genesis. NF-κB and EGFR play cooperating roles during hepatolithiasis carcinogenesis process. Over expression of EGFR is related with poor differentiation and prognosis of tumor.
目的总结1例非肝移植胆管铸型患者的诊治过程。 方法对1例非肝移植胆管铸型患者的临床资料、辅助检查资料及治疗效果进行分析，并进行文献复习。 结果1例非肝移植胆管铸型患者经生化检查、胆胰管水成像（MRCP）、上腹部CT等检查诊断为胆囊结石伴胆囊炎、胆总管结石伴低位胆管梗阻。采取开腹胆道探查、胆道镜检查取石、胆囊切除、T管引流手术治疗。术中见胆囊缩小，与周围大网膜膜性粘连，肝十二指肠韧带水肿，胆总管扩张呈充盈状态。胆道镜下见肝内外胆管轻度扩张，肝外胆管壁炎性水肿较重，大量纤维素附着；胆总管末端通畅，可见胰管开口，进而诊断为胆胰合流异常。以胆道镜从胆总管内取出1枚结石，约2.0 cm×1.5 cm×1.0 cm大，质硬，表面光滑；另取出1枚胆管铸型，约3.5 cm×0.3 cm×0.3 cm大，质脆易碎，表面粗糙。该患者的手术顺利，切除胆囊术后病理学检查示慢性胆囊炎改变。术后恢复良好，未出现胆汁漏、出血等并发症。术后随访1年，复查上腹部CT提示无结石复发，肝功能各项指标均正常。 结论非肝移植胆管铸型较少见，胆胰合流异常是非肝移植胆管铸型和胆管结石形成的原因之一。胆道镜是清除胆管铸型和观察胆管内结构的重要工具。
Using radioimmunoassay (RIA) and immunohistochemical LASB technique, the level of serum estradiol (E2), testosterone (T), progesterone (P), estrogen receptors (ER) and progesterone receptors (PR) in 30 male patients with gallstones were detected. The results showed that the level of serum P, E2/T and PR was higher. This suggests that the metabolic disorder of gonadal hormones play an important role in gallstone formation.
