| 1 | Endoscopic management of postcholecystectomy biliary leakage显示文摘BACKGROUND: Biliary leak is an uncommon but significant complication following cholecystectomy. Endotherapy is an established method of treatment. However, the optimal intervention is not known. METHOD: Eighty-five patients with postcholecystectomy biliary leaks from July 2000 to March 2009 were retrospectively evaluated. RESULTS: The study population was 20 males and 65 females with a mean age of 42.47 years. Patients presented with abdominal pain (46), jaundice (23), fever (23), abdominal distension (42), or bilious abdominal drain (67). Endoscopic retrograde cholangiopancreatography detected a leak at the cystic duct stump in 45 patients, stricture with middle common bile duct leak in 4, leak from the right hepatic duct in 3, and a ligated common bile duct in 32. Twelve also had bile duct stones. One had a broken T-tube with stones Endotherapy was possible in 53 patients. Three patients with stones, one with a broken T-tube with stones, and 4 with stricture of the common bile duct with a leak were managed with sphincterotomy and stenting. Eight patients with a cystic duct stump leak with stones were managed with sphincterotomy and stone extraction. Three outpatients and 12 inpatients with a cystic duct stump leak were managed with sphincterotomy and stent and sphincterotomy and nasobiliary drain, respectively. Five patients with a cystic duct stump leak were managed with stenting. Sixteen with coagulopathy were managed with only nasobiliary drain (9) or stent (7). Leak closure was achieved in 100% patients Four developed mild pancreatitis which improved with conservative treatment.CONCLUSIONS: Endoscopic intervention is a safe and effective method of treatment of postcholecystectomy biliary leaks. However, management should be individualized based on factors such as outpatients or inpatients, presence of stone, stricture, ligature, or coagulopathy. | Virendra Singh Gurpreet Singh Ganga R Verma Rajesh Gupta | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，4： | 9 |
| 2 | Contrast-free air cholangiography-assisted unilateral plastic stenting in malignant hilar biliary obstruction显示文摘BACKGROUND:Endoscopic palliation in malignant hilar biliary obstruction requires endoscopic retrograde cholangiopancreatography (ERCP),whereas contrast injection leads to cholangitis.Contrast-free metal stenting with or without magnetic resonance cholangiopancreatography (MRCP) has shown encouraging results,but MRCP and metal stents are costly.There have been no reports on the use of air cholangiography.METHODS:We prospectively evaluated the role of air cholangiography-assisted unilateral plastic stenting in 10 patients with type Ⅱ malignant hilar biliary obstruction.A retrospectively analysed group of 10 patients treated with contrast-free unilateral metal stenting served as historical controls.RESULTS:Ten patients with unresectable type Ⅱ malignant hilar biliary obstruction were studied.Air cholangiography detected type Ⅱ obstruction in all patients,similar to MRCP.The patients underwent unilateral stenting.Successful endoscopic drainage was achieved in all patients.The mean patency of the stent was 95.8±17.5 days in the study group and 143.9±115.1 days in the control group (P=0.20).The mean survival was 121.8±41.6 days in the study group and 154.9±122.5 days in the control group (P=0.42).KaplanMeier analysis showed an estimated median survival of 100:95% CI (65.9,134.1) days in the study group and 98:95% CI (84.1,111.9) days in the control group (P=0.62).Cholangitis occurred in none of the patients and there were no 30-day deaths nor major complications.Air cholangiographyassisted unilateral plastic stenting was cheaper than contrastfree unilateral metal stenting.CONCLUSION:Air cholangiography-assisted unilateral plastic stenting is as safe and effective as contrast-free unilateral metal stenting in type Ⅱ malignant hilar biliary obstruction for palliating patients,but it is cheaper. | Virendra Singh Gurpreet Singh Vikas Gupta Rajesh Gupta Rakesh Kapoor | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，1： | 7 |

| 4 | 沙棘饮料的化学成分和最优口感的研究显示文摘沙棘(Hippophae rhamnoids L.),属于胡颓子属,在印度喜马偕尔邦地区称作'Chharma and Surch',沙棘能够在这种非常恶劣的气候条件下自然生长。本文介绍了制作沙棘饮料的一系列程序和如何储存饮料120d而不使其变质的方法。沙棘果实采自印度喜马偕尔邦河谷。用碎浆机提取沙棘汁,制作沙棘饮料要准备好合适比例的沙棘汁和制作饮料所需的糖。随着果浆比例的升高,维生素C的含量明显增加(P≤0.05),随着贮藏时间的延长,维生素C的含量明显降低。而随着糖和果浆的增加以及储存期的延长,还原性糖呈上升趋势。当饮料中果浆和糖的比例分别为10%和13%、12.5%和13%、15%和15%时,饮料最为宜口,给于较高的评价。在喜马偕尔邦,人们一直认为沙棘具有商业价值,但是其价值在此前一直没有得到足够的重视。 | 杨唐英 温秀凤 Shipra Saklani H.
