| 1 | Is bactibilia a predictor of poor outcome of pancreaticoduodenectomy?显示文摘BACKGROUND:Although bile infection has been proposed to increase infective complications following pancreaticoduodenectomy,its association with infective complications and non-infective complications like pancreatic fistula is still controversial.METHODS:Seventy-six patients who had undergone pancreaticoduodenectomy between July 2007 and December 2008 were included in a prospective database and their data analyzed.In all patients intraoperative bile from the bile duct was cultured.Preoperative,intra-operative,and post-operative variables were recorded and analyzed.RESULTS:Bile culture showed positive growth in 35 patients and negative growth in 41.Twenty patients in the positive group underwent ERCP and stenting.The patients with a positive bile culture had a higher incidence of infective complications including intra-abdominal abscess (n=8),wound infection (n=27),bacteremia (n=10),and renal insufficiency (n=9).There was no increase in the rate of non-infective complications of pancreaticoduodenectomy including pancreatic fistula (n=7),delayed gastric emptying (n=9),and post-operative hemorrhage (n=3).The hospital stay was significantly prolonged in the patients with a positive bile culture (P=0.0002).CONCLUSIONS:Pre-operative biliary drainage is significantly associated with bile infection,and bile infection increases the overall rates of infective complications and renal insufficiency.Because of the high incidence of complications is associated with infected bile,routine intra-operative bile culture is recommended in patients undergoing pancreaticoduodenectomy.Pre-operative prophylaxis is dependent on sensitivity of cases to perioperative antibiotics and intraoperative bile culture report.Because of its significant association with infected bile,biliary stenting should be used in strictly selected cases. | Sivanpillay Mahadevan Sivaraj Velayutham Vimalraj Palanichamy Saravanaboopathy Shanmugasundaram Rajendran Sathyanesan Jeswanth Palaniappan Ravichandran Rosy Vennilla Rajagopalan Surendran | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，1： | 2 |

| 11 | Rapid flood inundation mapping by differencing water indices from pre-and post-flood Landsat images显示文摘Following flooding disasters,satellite images provide valuable information required for generating flood inundation maps.Multispectral or optical imagery can be used for generating flood maps when the inundated areas are not covered by clouds.We propose a rapid mapping method for identifying inundated areas based on the increase in the water index value between the pre-and post-flood satellite images.Values of the Normalized Difference Water Index(NDWI)and Modified NDWI(MNDWI)will be higher in the post-flood image for flooded areas compared to the pre-flood image.Based on a threshold value,pixels corresponding to the flooded areas can be separated from non-flooded areas.Inundation maps derived from differencing MNDWI values accurately captured the flooded areas.However the output image will be influenced by the choice of the pre-flood image,hence analysts have to avoid selecting pre-flood images acquired in drought or earlier flood years.Also the inundation maps generated using this method have to be overlaid on the post-flood satellite image in order to orient personnel to landscape features.Advantages of the proposed technique are that flood impacted areas can be identified rapidly,and that the pre-existing water bodies can be excluded from the inundation maps.Using pairs of other satellite data,several maps can be generated within a single flood which would enable emergency response agencies to focus on newly flooded areas. | Ramesh SIVANPILLAI Kevin M.JACOBS Chloe M.MATTILIO Ela V.PISKORSKI | 2021 | Frontiers of Earth Science2021，15，1： | 1 |
