Endoscopic management of postcholecystectomy biliary leakage

引用

Hepatobiliary & Pancreatic Diseases International 2010年第4期9卷 409-413页

作者： Virendra Singh Gurpreet Singh Ganga R Verma rajesh gupta Departments of Hepatology Postgraduate Institute of Medical Education and Research Departments of Surgery Postgraduate Institute of Medical Education and Research

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 ***: 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.

Landscaping and performance of some aesthetic plant species in hot, arid conditions of India

引用

Journal of Forestry Research 2012年第2期23卷 305-309页

作者： rajesh Kumar gupta Pradeep Chaudhry Rameshwar Lal Srivastava Arid Forest Research Institute New Pali Road Jodhpur-342005 India

Establishment of ornamental and aesthetic plants in hot, arid conditions of India is difficult due to the prevailing climatic, edaphic and biotic factors. Effect of turfgrass on the growth of ornamental plants in hot arid conditions has not been studied so far anywhere in the world. A study was conducted on the campus of Arid Forest Research Institute, Jodhpur, India to assess the performance of a few ornamental plant spe- cies in combination with turfgrass and without turfgrass with respect to different soil tilling intervals. Growth of plants was better with turfgrass than without turfgrass. We suggest adopting a soil tilling interval of 30 days to achieve optimum growth of ornamental plant species in terms of height and crown diameter. Our results can help reduce labor costs and achieving better landscapes in fewer days in hot urban conditions of Indian sub continent.

Background:Guidelines recommend that contrast-enhanced computed tomography(CT)should be carried out 72 hours after onset of an attack of acute pancreatitis(AP).However,the exact time beyond 72 hours at which CT will produce the best diagnostic yield for local complications,or whether doing a CT early in acute pancreatitis has any adverse effect on the course of disease,is not ***:The medical records of 214 consecutive patients with AP were analysed retrospectively and these patients were divided into two groups:the early CT group(CT done at 4–5 days after the onset of pain)and the late CT group(CT done in days 6–14 following onset of pain).The two groups were compared for differences in clinical outcomes and prognostic information obtained from CT,such as detection of pancreatic necrosis and local complications,and CT severity ***:Of 214 patients[143(66.8%)males;mean age 39.87613.52 years],21 patients were excluded as they did not undergo CT or CT was done more than 14 days after onset of an attack of *** early CT group included 114 patients,whilst the late CT group had *** mean CT severity index was higher in the late CT group(6.6562.27 vs.5.5262.7;P=0.005).The incidence of persistent organ failure in the early group was no different from that of the late group(38.6%vs.49.4%;P=0.143).Local complications were detected more often in the late CT group(84.8%vs.68.4%;P=0.011).There was no difference between the two groups in the need for percutaneous drainage,surgery,or mortality(all P>0.05).Conclusions:Although performing early CT does not adversely affect the outcome in AP,CT carried out more than 5 days after the onset of symptoms may detect more local complications.
