Abstract: the number of times an article is cited in scientific journals reflects its impact on a specific biomedical field or specialty and reflects the impact of the authors’ creativity. Our objective was to identify, and analyze the characteristics of the 100 most frequently cited articles published in journals dedicated to general surgery and its close subspecialties. Using the database (1945-1995) of the Science Citation Index of the Institute for Scientific Information. 1500 articles cited 100 times and more were identified and the top 100 articles selected for further analysis. The 100 articles were published between 1931 and 1990. with more than two-thirds of them published after 1960. The mean number of citations per article was 405, (range 278-1013). Altogether, 84 of the articles originated from North America (USA 78, Canada 6) and the UK (12). New York State led the list of U.S. states with 14, and Harvard and Columbia University led the list of institutions with 6 articles each. The 100 articles were published in 10 surgical journals led by the Annals of Surgery (n = 40), followed by Surgery (n = 15), Archives of Surgery (n = 12), Surgery, Gynecology and Obstetrics (n = 11), and British Journal of Surgery (n = 10). A total of 86 of the articles reported clinical experiences, 6 were clinical review articles, and 14 dealt with basic science. Eighteen articles reported a new surgical technique and six a prosthetic device. Gastrointestinal surgery and trauma and critical care led the list of the surgical fields, each with 25 articles, followed by vascular surgery (n = 15). Thirty-four persons authored two or more of the top-cited articles. This list of the top-cited papers identifies seminal contributions and their originators, facilitating the understanding and discourse of modern surgical history and offering surgeons hints about what makes a contribution a ‘top-cited classic,’ To produce such a ‘classic’ the surgeon and his or her group must come up with a clinical or nonclinical innovation, observation, or discovery that has a long-standing effect on the way we practice-be it operative or nonoperative. Based on our findings, to be well cited such a contribution should be published in the English language in a high-impact journal. Moreover, it is more likely to resonant loudly if it originates from a North American or British ‘ivory tower.’.

Abstract: Even though, in theory, a new surgical technique should traverse all the stages established for drugs before being introduced into medical practice, it is suspected that many surgical procedures are utilized without having rigorously evaluated their efficacy and safety. With the aim of identifying the methodologic aspects currently employed for assessing new surgical procedures, a descriptive bibliographic study was carried out. Altogether, 75 journal articles published from 1996 to 1998 were reviewed. The papers must have come from studies carried out with the expressed objective of evaluating a surgical procedure and were selected through MEDLINE or directly from six prestigious medical journals (three specifically surgical and three general). of the reviewed articles, 47% were retrospective studies, and the rest were prospective studies. More than 40% of the retrospective studies omitted some basic methodologic features, namely a description of the patients’ source or a definition of the inclusion criteria. Among the 41 prospective articles, only 35 used a control group and 15 did not employ random allocation. Other basic issues, such as the sample size or inclusion of prognostic factors in the analysis, were present in fewer than 50% of the articles. It seems there is consensus about admitting that rigorous assessment of new surgical treatments should be an unavoidable condition before introducing such treatment into practice. The facts demonstrate that this principle is not being followed.

Abstract: Sparganosis is a seldom encountered disease of the breast. Based on the results of previous studies and our own experience, we investigated the clinical characteristics of breast sparganosis. Four patients who were treated for breast sparganosis at Samsung Medical Center were included in the study, and additional data were retrieved from the Index Medicus and the Science Citation Index (SCI). The Korean Medical (KM) database and the Korean Association of Medical Journal Editors (KAMJE) database were searched to include information from Korean journals that is not included in international citation indexes. Among 35 patients, 8 (32%) had a record of oral ingestion of an intermediary host. All patients presented with a breast mass, with migration in 6 cases (25%) and pain or an itching sensation in 6 cases (25%). Elongated tubular structures were found in the subcutaneous layer in 22 cases (88%) during radiologic exam. All patients underwent complete surgical excision. Twenty-seven of 29 (93.1%) patients’ spargana was separated and confirmed grossly. Histologically, granulomatous inflammation was the most common feature. A single worm was extracted in 16 cases (76.2%) and 5 cases (23.8%) had multiple worms. Sparganosis tends to present as a suspicious mass in the subcutaneous layer of the breast. Complete surgical excision is the treatment of choice, with careful postoperative surveillance.

Abstract: Background Anastomotic configurations may be a predictor of postoperative recurrence for Crohn’s disease. One previous meta-analysis showed side-to-side anastomosis was associated with fewer anastomotic leaks but did not reduce postoperative recurrence rates. After 2007, more articles that found distinct results were published. We aimed to update the meta-analysis comparing outcomes between side-to-side anastomosis and other anastomotic configurations after intestinal resection for patients with Crohn’s disease. Methods A literature search that included PubMed, EMBASE, the Science Citation Index, and the Cochrane Library was conducted to identify studies up to May 2012. Trials comparing side-to-side anastomosis with other anastomotic configurations for Crohn’s disease were analyzed. Sensitivity analysis and heterogeneity assessment were also performed. Results Eleven trials compared side-to-side with other anastomotic configurations were included. Overall, results showed a significant reduction in the overall postoperative complications [n = 777; odds ratio (OR) = 0.60; P = 0.01], but side-to-side anastomosis did not reduce the anastomotic leak rate (n = 879; OR = 0.48; P = 0.07), complications other than anastomotic leak (n = 777; OR = 0.72; P = 0.13), endoscopic recurrence rates [hazard ratio (HR) = 0.73; P = 0.07], symptomatic recurrence rates (HR = 0.74; P = 0.20), and reoperation rates for recurrence (HR = 0.37; P = 0.06). Sensitivity analysis including two randomized controlled trials found no significant differences in short-term complications between the two groups. Sensitivity analysis including nine trials comparing only stapled side-to-side anastomosis with other anastomotic configurations showed stapled side-to-side anastomosis could reduce reoperation rates (HR = 0.38; P = 0.01). Conclusions Side-to-side anastomosis did not reduce short-term complications and postoperative recurrence for Crohn’s disease. Stapled side-to-side anastomosis may lead to fewer reoperations needed for recurrence. Further randomized, controlled trials should be conducted for confirmation of recurrent events.

Abstract: The acute surgical unit (ASU) is a novel model for the provision of emergency general surgery care. The ASU model was initially developed in New South Wales hospitals during 2005 and 2006. Several studies have analysed the effects on patient outcomes and timeliness of care for nontrauma patients presenting with acute general surgical conditions. The purpose of this study was to perform a meta-analysis to determine the efficacy of the ASU model compared with the traditional on-call model for specific conditions. A systematic search was conducted using MEDLINE, PubMed, EMBASE, Current Contents Connect, Cochrane library, Google Scholar, Science Direct, and Web of Science. Original data were extracted from each study and used to calculate a pooled odd ratio (OR) and 95 % confidence interval (CI). The search identified 18 studies; appendectomy (n = 9), acute cholecystitis (n = 7), and small-bowel obstruction (SBO) (n = 2). In the appendectomy cohort, the proportion of appendicular perforation were similar in pre-ASU and ASU period (OR 1.02, 95 % CI 0.77-1.37, p = 0.13). The incidence of complications in the appendectomy cohort was significantly lower in the ASU group; 14.5 % pre-ASU and 10.9 % post-ASU (OR 1.649, 95 % CI 0.732-3.714, p = 0.009). The negative appendectomy rate was similar for the pre- and post-ASU groups (OR 1.07, 95 % CI 0.88-1.31, p = 0.83). Likewise the conversion rate to open surgery and total hospital stay were similar between the two groups. The proportion of night time operations reduced significantly in the ASU period (OR 1.9, 95 % CI 1.32-2.74, p = 0.001). In the acute cholecystitis cohort, the conversion rate to open surgery was significantly higher in the pre-ASU group (15.1 %) compared with the post-ASU group (7.5 %) (OR 1.879, 95 % CI 1.072-3.293, p = 0.04) The incidence of complications was higher in the pre-ASU (14 %) compared with the post-ASU (6.8 %) group (OR 2.231, 95 % CI 1.372-3.236, p = 0.03). The mean hospital stay was significantly lower in the ASU period (5.3 vs. 3.7 days, p = 0.0063). There was insufficient data available to analyse outcomes for SBO. The ASU model provides a safe surgical environment for patients and is associated with a reduced complication rate for appendectomy and laparoscopic cholecystectomy for acute cholecystitis. There is a reduced conversion rate and a shorter length of stay for patients with acute cholecystitis. Overall, the ASU model has translated to better outcomes for patients presenting with acute general surgical conditions.

Abstract: The optimal technique to cure strangulated inguinal hernia remains controversial. The use of mesh in cases of strangulated hernia is still debated due to the potential risk of infection. This systematic review aimed to determine whether or not the mesh repair technique is associated with a higher risk of surgical site infection than non-mesh techniques for strangulated inguinal hernias in adults. An electronic search of the relevant literature was performed on 15 December 2012 using the following databases: MEDLINE, the Cochrane Library, Scopus, Embase, and the Web of Science. Articles reporting a comparison between the mesh repair technique and a non-mesh technique to treat strangulated inguinal hernias in adults, and published in the English or French language in a peer-reviewed journal, were considered for analysis. The quality of randomized controlled trials (RCTs) was assessed using the Jadad scoring system. To assess the quality of non-randomized trials, we used the Methodological Index for Non-Randomized Studies (MINORS). A total of 232 papers was found in the initial search; nine were included in the meta-analysis. The wound infection rate in the mesh repair technique group was lower than in the control group, with a trend towards significance (odds ratio [OR] 0.46, 95 % confidence interval [CI] 0.20-1.07; p = 0.07). The hernia recurrence rate was lower in the mesh repair group (OR 0.2, 95 % CI 0.05-0.78; p = 0.02). The mesh repair technique is a good option for the treatment of strangulated inguinal hernias in adults, giving an acceptable wound infection rate and fewer recurrences than non-mesh repair. Our study does not allow us to recommend the use of mesh in cases of bowel resection. We emphasize that, except the two RCTs, the results are predicated on patient selection bias by careful surgeons. Further RCTs are required to obtain more powerful evidence-based data.

Abstract: Although laparoscopic posterior fundoplication (LPF) i.e., Nissen or Toupet have the proven efficacy for controlling gastro-esophageal reflux surgically, there remain problems with postoperative dysphagia and gas bloat syndrome. To decrease some of these postoperative complications, laparoscopic anterior fundoplication (LAF) was introduced. The aim of this study was to conduct a meta-analysis and systematic review of randomized controlled trials (RCTs) to investigate the merits and drawbacks of LPF versus LAF for the treatment of gastro-esophageal reflux disease (GERD). A search of Medline, Embase, Science Citation Index, Current Contents, PubMed, ISI Web of Science, and the Cochrane Database identified all RCTs comparing different types of LPF and LAF published in the English Language between 1990 and 2013. The meta-analysis was prepared in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) statement. Data was extracted and analyzed on ten variables which include dysphagia score, heartburn rate, redo operative rate, operative time, overall complications, rate of conversion to open, Visick grading of satisfaction, overall satisfaction, length of hospital stay, and postoperative 24-h pH scores. Nine trials totaling 840 patients (anterior = 425, posterior = 415) were analyzed. There was a significant reduction in the odds ratio for dysphagia in the LAF group compared to the LPF group. Conversely, significant reduction in the odds ratio for heartburn was observed for LPF compared to LAF. Comparable effects were noted for both groups for other variables which include redo surgery, operating time, overall complications, conversion rate, Visick’s grading, patients’ satisfaction, length of hospital stay, and postoperative 24-h pH scores. Based on this meta-analysis, LPF compared to LAF is associated with significant reduction in heartburn at the expense of higher dysphagia rate on a short- and medium-term basis. We therefore conclude that LPF is a better alternative to LAF for controlling GERD symptoms.
