| 1 | Omental flaps reduces complications after pancreaticoduodenectomy显示文摘BACKGROUND:Major complications after pancreaticoduodenectomy are usually caused by a leaking pancreaticojejunal anastomosis.Omental flaps around various anastomoses were used to prevent the formation of fistula.METHODS:We reviewed 147 patients who had undergone pancreaticoduodenectomy between March 2006 and March2012.The patients were divided into 2 groups according to the application of omental flaps around various anastomoses:group A(101 patients)who underwent omental wrapping procedure;group B(46 patients)who did not undergo the omental wrapping procedure.Perioperative data of the two groups were reviewed to assess the effectiveness of omental flap procedure in the prevention of pancreatic fistula and other complications.RESULTS:No differences were observed in the clinical characteristics between the 2 groups.The incidences of pancreatic fistula(4.0%vs 17.4%),post-pancreatectomy hemorrhage(0vs 6.5%),biliary fistula(1.0%vs 13.0%),and delayed gastric emptying(4.0%vs 17.4%)were significantly less frequent in group A.The overall morbidity(18.8%vs 47.8%)and hospital stay(8.3 vs 9.6 days)were also significantly lower in group A than in group B.CONCLUSIONS:Omental flaps around various anastomoses after pancreaticoduodenectomy can reduce the incidences of pancreatic fistula,biliary fistula,post-pancreatectomy hemorrhage and delayed gastric emptying.This procedure is simple and effective to reduce the overall morbidity after pancreaticoduodenectomy. | Omar J Shah Sadaf A Bangri Manmohan Singh Reyaz A Lattoo Mohammad Y Bhat | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，3： | 19 |
| 2 | Radiation exposure and reduction in the operating room: Perspectives and future directions in spine surgery显示文摘Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy. In attempts to reduce radiation-associated health risks, radiation safety has become an important topic in the medical field. All practitioners, regardless of practice setting, can practice radiation safety techniques including shielding and distance to reduce radiation exposure. Additionally, optimization of fluoroscopic settings and techniques can be used as an effective method of radiation dose reduction. New imaging modalities and spinal navigation systems have also been developed in an effort to replace conventional fluoroscopy and reduce radiation doses. These modalities include Isocentric Three-Dimensional C-Arms, O-Arms, and intraoperative magnetic resonance imaging. While this influx of new technology has advanced radiation safety within the field of spine surgery, more work is still required to overcome specific limitations involving increased costs and inadequate training. | Ankur S Narain Fady Y Hijji Kelly H Yom Krishna T Kudaravalli Brittany E Haws Kern Singh | 2017 | World Journal of Orthopedics2017，8，7： | 9 |
| 3 | Randomised controlled trial comparing modified Sano's and narrow band imaging international colorectal endoscopic classifications for colorectal lesions显示文摘AIM To assess the utility of modified Sano′s(MS) vs thenarrow band imaging international colorectal endoscopic(NICE) classification in differentiating colorectal polyps.METHODS Patients undergoing colonoscopy between 2013 and 2015 were enrolled in this trial.Based on the MS or the NICE classifications,patients were randomised for real-time endoscopic diagnosis.This was followed by biopsies,endoscopic or surgical resection.The endoscopic diagnosis was then compared to the final(blinded) histopathology.The primary endpoint was the sensitivity(Sn),specificity(Sp),positive predictive value(PPV) and negative predictive value(NPV) of differentiating neoplastic and non-neoplastic polyps(MSⅡ/Ⅱo/Ⅲa/Ⅲb vs I or NICE 1 vs 2/3).The secondary endpoints were 'endoscopic resectability'(MSⅡ/Ⅱo/Ⅲa vs Ⅰ/Ⅲb or NICE 2 vs 1/3),NPV for diminutive distal adenomas and prediction of post-polypectomy surveillance intervals.RESULTS A total of 348 patients were evaluated.The Sn,Sp,PPV and NPV in differentiating neoplastic polyps from non-neoplastic polyps were,98.9%,85.7%,98.2% and 90.9% for MS;and 99.1%,57.7%,95.4% and 88.2% for NICE,respectively.The area under the receiver operating characteristic curve(AUC) for MS was 0.92(95%CI:0.86-0.98);and AUC for NICE was 0.78(95%CI:0.69,0.88).The Sn,Sp,PPV and NPV in predicting 'endoscopic resectability' were 98.9%,86.1%,97.8% and 92.5% for MS;and 98.6%,66.7%,94.7% and 88.9% for NICE,respectively.The AUC for MS was 0.92(95%CI:0.87-0.98);and the AUC for NICE was 0.83(95%CI:0.75-0.90).The AUC values were statistically different for both comparisons(P = 0.0165 and P = 0.0420,respectively).The accuracy for diagnosis of sessile serrated adenoma/polyp(SSA/P) with high confidence utilizing MS classification was 93.2%.The differentiation of SSA/P from other lesions achieved Sp,Sn,PPV and NPV of 87.2%,91.5%,89.6% and 98.6%,respectively.The NPV for predicting adenomas in diminutive rectosigmoid polyps(n = 150) was 96.6% and 95% with MS and NICE respectively.The calculated accuracy of post-polypectomy surveillance for MS group was 98.2%(167 out of 170) and for NICE group was 92.1%(139 out of 151).CONCLUSION The MS classification outperformed the NICE classification in differentiating neoplastic polyps and predicting endoscopic resectability.Both classifications met ASGE PIVI thresholds. | Leonardo Zorrón Cheng Tao Pu Kuan Loong Cheong Doreen Siew Ching Koay Sze Pheh Yeap Amanda Ovenden Mahima Raju Andrew Ruszkiewicz Philip W Chiu James Y Lau Rajvinder Singh | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，9： | 4 |
| 4 | Effect of site amplification on inelastic seismic response显示文摘The available models for eff ective periods of site and structure are reviewed in context of frequency tuning in the inelastic seismic response of soil-structure system. The eff ect of seismic intensity and ductility demand, on the eff ective periods, is investigated, and inelastic site amplifi cation is shown to be strongly correlated to the normalized eff ective period. Two non-dimensional parameters, analogous to the conventional site amplifi cation factors in codes, are defi ned to quantify the inelastic site amplifi cation. It is shown that the inelastic site amplifi cation factor (i.e. ratio of constant ductility spectral ordinates at soil site to those at rock outcrop) is able to represent the site eff ects more clearly, as compared to the inelastic site amplifi cation ratio (i.e. ratio of inelastic spectral ordinates at soil site to the corresponding elastic spectral ordinates at rock outcrop). Further, the peak in the amplifi cation factor corresponding to the eff ective site period diminishes rapidly with increasing ductility demand. | Adhikary S Singh Y | 2019 | Earthquake Engineering and Engineering Vibration2019，18，3： | 4 |

| 6 | A selective approach to the surgical management of periampullary cancer patients and its outcome显示文摘BACKGROUND: Pancreaticoduodenectomy is a high risk, complex, technically challenging operation associated with significant perioperative morbidity and mortality. This study on the surgical management of periampullary cancer patients is based on our experience in a period of nearly 13 years.METHODS: The study was conducted on two groups of patients: group A included 42 patients who were treated between January 2000 and September 2005 and group B included 134 patients who were treated between October 2005 to October 2012. Preoperative, intraoperative and postoperative details of all these patients were collected, tabulated and analyzed to assess the impact of the selective approach introduced in the department with effect from October 2005.RESULTS: Intraoperative details revealed highly significant differences in the management of the two groups of patients in respect of operative time (250.4 vs 126.6 minutes; P<0.001), operative blood loss (1070.2 vs 414.9 m L; P<0.001) and intraoperative blood transfusion (1.4 vs 0.2 units; P<0.001). Variations between the two groups in the frequency of complications were found to be statistically insignificant. However, the difference between the two groups in the overall morbidity of patients (47.6% vs 26.1%; P=0.009) and the length of their hospital stay (11.8 vs 7.8 days; P<0.001) were significant.CONCLUSION: A selective approach applied to the surgical management of periampullary cancer patients is a step in the right direction. | Omar J Shah Irfan Robbani Parveen Shah Sadaf A Bangri Irfan J Khan Mohammad Y Bhat Manmohan Singh | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，6： | 3 |
