Abstract: Aim. To evaluate the scientific impact of presentations, at the annual meetings of the Society of University Surgeons (SUS) and the Association for Academic Surgery (AAS). Methods. All Abstracts presented, at the 2002-2004 annual conferences were examined for publication rate (PR), publication citation (PC) and journal impact factor (IF). Results. Overall, 1200 abstracts from the SUS (n = 543, 45 %) and AAS (n = 657,55 %) were reviewed. One way ANOVA analysis of SUS results across session types demonstrated significant differences in PR (89 % plenary, 81 % parallel, 100 % basic science, 47 % resident conference, poster 76 %, p < 0.0001), but no difference in,PC (12.96 plenary, 9.66 parallel, 7.77 basic science, 8.23 resident conference, 8.21 poster, p = 0.25561) or IF (4.17 plenary, 3.50 parallel, 2.66 basic science, 3.12 resident conference 3.13 poster, p = 0.3947). AA S results demonstrated significant differences for PR (81 % plenary, 62 % parallel and 43 % poster, p < 0.0001), CR (8.33 plenary, 4.81 parallel, and 4.78 poster, p = 0.006) and IF (3.75 plenary, 2.64 parallel, and 2.73 poster, p = 0.0124). Comparison of abstracts between meetings demonstrated a higher overall PR, CR and IF for SUS publications (p < 0.0001). Conclusion. These data suggest that SUS and, AAS presentations constitute high-quality research, Trends towards higher PR, PC and IF for plenary sessions indicate that the review process properly stratifies. research. Statistically higher impact measures for SUS presentations are consistent with the more mature research careers of SUS members.

Abstract: Background. Many studies have evaluated serum levels of procalcitonin (PCT) as a predictor in the development of severe acute pancreatitis (SAP) and infected pancreatic necrosis (H-W). This study assesses the value of PCT as a marker of development of SAP and IPN. Methods. MEDLINE, Web of Science, the Cochrane clinical trials register, and international conference proceedings were searched systematically for prospective studies, which evaluated the usefulness of PCT as a marker of SAP and IPN. The sensitivity, specificity, and diagnostic odds ratios (DORs) were calculated for each study, and the study quality and heterogeneity among the studies were evaluated. Results. Twenty-four of 59 studies identified were included in data extraction. The sensitivity and specificity of PCT for development of SAP were 0.72 and 0.86, respectively (area under the curve [AUC] = 0.87; DOR = 14.9; 95% confidence interval [CI] = 5.6-39.8), albeit with a significant degree of heterogeneity Q = 28.56, P .01). The sensitivity and specificity of PCT for prediction of infected pancreatic necrosis were 0.80 and 0.91 (AUC = 0.91; DOR = 28.3; 95% CI = 13.8-58.3) with no significant heterogeneity Q = 7.83, P = .18). No significant heterogeneity was observed among the studies when only higher quality studies (AUC = 0.91; DOR = 30.7; 95% CI = 10. 7-87.8) or studies that used a cutoff PCT level >0.5 ng/mL (AUC = 0.88, 32.8; 95% CI = 10.1-106.6) were included. Conclusion. Serum measurements of PCT may be valuable in predicting the severity of acute pancreatitis and the risk of developing infected pancreatic necrosis. (Surgery 2009;146:72-81.).

Abstract: Background: Concerti has long existed regarding the possible iatrogenic spread of variant Creutzfeldt-Jakob disease (v-CJD) through surgery. This had been fueled by recent reports of bovine spongiform encephalopathy in U.S. cattle and the first probable case of blood transmission of v-CJD in the UK. Methods: Systematic review of experimental and non-experimental Studies. Studies identified from searches of Medline. Embase. Cochrane Library. Science Citation Index medical databases, searching bibliographies of retrieved papers, and personal communication with international experts in the field. Results: Six articles satisfied our search criteria. Evidence stems from case reports, case series, and cross-sectional Studies. There are no published cases of surgically transmitted v-CJD. Conclusion: We found evidence of v-CJD prion agents in the spleen, appendix. rectum, and adrenal glands of affected patients and evidence of v-CJD priori in the appendix of patients in the preclinical stage of the disease. The risk of transmission of v-CJD prion during abdominal surgery is Currently unquantifiable.

Abstract: Background Recent studies have added to the controversy regarding the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of patients with acute biliary pancreatitis. This debate is due in part to a marked difference between the trials regarding the definition of “complication” as an outcome. This study sought to determine the effect of early ERCP versus conservative treatment on local pancreatic complications (defined by the current classification) experienced by patients with acute biliary pancreatitis. Methods Electronic databases (Cochrane Central Register of Controlled Trials, MEDLINE, Science Citation Index) and conference proceedings were searched for relevant randomized controlled trials up to December 2007. The effect of both treatment strategies on local pancreatic complications was calculated with random-effects models. Results Five trials involving 717 patients were included in this systematic review. Pooled analysis of all the patients with acute pancreatitis did not demonstrate a statistically significant difference between the two treatment strategies (relative risk [RR], 0.94, 95% confidence interval [CI], 0.63-1.40, p = 0.62). Similar results were observed after subgroup analysis based on the severity of disease as follows: mild acute pancreatitis (RR, 0.79, 95% CI, 0.26-2.47, p = 0.69), severe acute pancreatitis (RR, 0.77, 95% CI, 0.30-1.98, p = 0.59). Conclusion The early use of ERCP did not result in a significantly reduced risk of local pancreatic complications for either patients with mild acute pancreatitis or those with severe form of the disease.

Abstract: In the past 20 years the surgical simulator market has seen substantial growth. Simulators are useful for teaching surgical skills effectively and with minimal harm and discomfort to patients. Before a simulator can be integrated into an educational program, it is recommended that its validity be determined. This study aims to provide a critical review of the literature and the main experiences and efforts relating to the validation of simulators during the last two decades. Subjective and objective validity studies between 1980 and 2008 were identified by searches in PUBMED, Cochrane, and Web of Science. Although several papers have described definitions of various subjective types of validity, the literature does not offer any general guidelines concerning methods, settings, and data interpretation. Objective validation studies on endourological simulators were mainly characterized by a large variety of methods and parameters used to assess validity and in the definition and identification of expert and novice levels of performance. Validity research is hampered by a paucity of widely accepted definitions and measurement methods of validity. It would be helpful to those considering the use of simulators in training programs if there were consensus on guidelines for validating surgical simulators and the development of training programs. Before undertaking a study to validate a simulator, researchers would be well advised to conduct a training needs analysis (TNA) to evaluate the existing need for training and to determine program requirements in a training program design (TPD), methods that are also used by designers of military simulation programs. Development and validation of training models should be based on a multidisciplinary approach involving specialists (teachers), residents (learners), educationalists (teaching the teachers), and industrial designers (providers of teaching facilities). In addition to technical skills, attention should be paid to contextual, interpersonal, and task-related factors.

Abstract: Although laparoscopic fundoplication is an effective, minimally invasive surgical technique for gastroesophageal reflux disease (GERD) that failed to be treated with medicine, with wide implementation its technical limitations have become increasingly clear. Recently, robot-assisted laparoscopic fundoplication (RALF) was considered a new approach that makes up for the deficiency of conventional laparoscopic fundoplication (CLF). This systematic review aimed to assess the feasibility and efficiency of robot-assisted laparoscopic fundoplication for GERD. Two reviewers independently searched and identified seven randomized controlled trials (RCTs) and four clinical controlled trials (CCTs) of RALF versus CLF for GERD in the Cochrane database, Medline, Embase, and Science citation index between 2001 and 2009. The main outcomes were operating time, complication rate, hospital stay, and costs. The meta-analysis was performed by Review Manager 5.0 software. The effect size of the clinical outcomes was evaluated by odds ratio (OR), weighted mean difference (WMD), and standard mean difference (SMD) according to different data type. Heterogeneity and sensitivity analysis were used to account for rationality of pooling data and sources of heterogeneity. Of 483 studies found, a total of 11 trials were included in this review, among 533 patients, 198 patients underwent RALF and 335 patients underwent CLF. The results of meta-analysis showed that the postoperative complication rate (OR = 0.35, 95% CI = [0.13, 0.93], p = 0.04) is lower for RALF, but the total operating time (WMD = 24.05, 95% CI = [5.19, 42.92], p = 0.01) is longer for RALF compared with those for CLF. Statistically, there was no significant difference between the two groups with regard to perioperative complication rate (OR = 0.67, 95% CI = [0.30, 1.48], p = 1.00) and length of hospital stay (WMD = 0.00, 95% CI = [-0.25, 0.26], p = 0.04). Systematic review of the literature indicates that RALF is a feasible and safe alternative to surgical treatment of GERD. However, since it lacks obvious advantages with respect to operating time, length of hospital stay and cost, RALF has limitations for its extensive application in clinics.

Abstract: There is no clear answer regarding use of precut technique versus conventional method in achieving successful biliary cannulation. To compare the effectiveness of precut technique with that of conventional biliary cannulation by meta-analysis of available randomized controlled trials (RCTs). Databases including MEDLINE, EMBASE, Cochrane Library, and Science Citation Index updated to July 2009 were searched. Main outcome measures were success rates of biliary cannulation, incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) complications, and post-ERCP pancreatitis rate. Meta-analysis of these clinical trials was performed. Six RCTs were included. The primary biliary cannulation rate reported with precut and conventional techniques was 89.3 and 78.1%, respectively. Pooled analysis of all selected studies comparing precut cannulation technique with conventional techniques yielded an odds ratio (OR) of 2.05 [95% confidence interval (CI): 0.64-6.63]. Pooled analysis comparing post-ERCP pancreatitis rates for the precut-cannulation groups with those for the conventional-method groups yielded an rate ratio (RR) of 0.46 (95% CI: 0.23-0.92). This meta-analysis shows that the precut technique does not increase the primary cannulation rate. However, the technique reduces the risk of post-ERCP pancreatitis compared with conventional technique. Further large, well-performed, randomized controlled studies are needed to confirm these findings.

Abstract: Background Oesophagectomy is one of the most challenging surgeries. Potential for morbidity and mortality is high. Minimally invasive techniques have been introduced in an attempt to reduce postoperative complications and recovery times. Debate continues over whether these techniques are beneficial to morbidity and whether oncological resection is compromised. This review article will analyse the different techniques employed in minimally invasive oesophagectomy (MIO) and critically evaluate commonly reported outcome measures from the available literature. Methods Medline, Embase, Science Citation Index, Current Contents, and PubMed databases were used to search English language articles published on MIO. Thirty-one articles underwent thorough analysis and the data were tabulated where appropriate. To date, only level III evidence exists. Where appropriate, comparisons are made with a meta-analysis on open oesophagectomy. Results Positive aspects of MIO include at least comparable postoperative recovery data and oncological resection measures to open surgery. Intensive care unit requirements are lower, as is duration of inpatient stay. Respiratory morbidity varies. Negative aspects include increased technical skill of the surgeon and increased equipment requirements, increased operative time and limitation with respect to local advancement of cancer. With increasing individual experience, improvements in outcome measures and the amenability of this approach to increasing neoplastic advancement has been shown. Conclusion MIO has outcome measures at least as comparable to open oesophagectomy in the setting of benign and nonlocally advanced cancer. Transthoracic oesophagectomy provides superior exposure to the thoracic oesophagus compared to the transhiatal approach and is currently preferred. No multicentre randomised controlled trials exist or are likely to come into fruition. As with all surgery, careful patient selection is required for optimal results from MIO.
