    Laparoscopic right colectomy: Road to safety surgery

    No full text
    Laparoscopic right hemicolectomy indicates a surgical technique for the removal of right-sided colon cancer; it nowadays represents an effective treatment for this disease, but it remains a demanding procedure, burdened by the risk of serious complications, especially in laparoscopic surgery. Indeed, a standard technique for the execution of this intervention does not exist. The purpose of this study is to suggest a standardization of the procedure advising some tips and tricks which could benefit its learning and its performance, helping operators to minimize the risk of major complications. After creation of pneumoperitoneum and port placement, the procedure is structured in consecutive steps: surgical field exposure, vascular dissection, coloparietal detachment, ileal and colic sectioning, anastomosis. During the intervention, the surgical plans and all the structures involved are identified and safeguarded. The entire demolition phase occurs in an anti-clockwise direction. An intracorporeal anastomosis is performed and enterotomies are closed using a two-layer, running barbed suture. During all phases, the assistant grabs and moves bowels in order to improve the field exposure and facilitate the operator's maneuvers

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Dual docking technique for robotic repair of simultaneous inguinal and umbilical hernia: A preliminary single center experience

    No full text
    Background: This study aimed to assess clinical results in terms of intraoperative outcomes, recovery and recurrence of our robotic technique for the treatment of patients affected by simultaneous inguinal and umbilical hernia, providing technical details to facilitate multiquadrant surgery in robotic hernia repair. Methods: Data from patients affected by simultaneous primary inguinal and umbilical hernia who underwent robotic repair with our dual docking technique was retrospectively analysed. Results: Fifteen patients were included. No intraoperative complications occurred. All patients achieved complete mobilisation within 7 h. The mean length of hospital stay was 21.6 h, with five patients discharged on the same day of surgery. There was no major complication and no recurrence within the median follow-up period of 673 days. Conclusions: This surgical technique shows optimal postoperative outcomes, such as early mobilisation and short length of stay. Our study provides an aid to surgeons performing multiquadrant robotic surgery for the treatment of abdominal hernias

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    A giant inguinal hernia in a patient with Ehlers-Danlos syndrome

    BACKGROUND: Inguinal hernia formation is a common event in patients with Ehlers-Danlos syndrome. Minimally invasive surgical technique for inguinal hernia repair is the same used in patients without EDS but it is related to more intraoperative and postoperative complications. AIM: Inour study, we present a case of inguinal hernia in a EDS patient successfully treated with a robotic transabdominal preperitoneal procedure (TAPP procedure). MATERIAL AND METHODS: We decided to perform a robotic TAPP with the DaVinci Xi® platform (Intuitive Surgical, Sunnyvale, USA) under general anaesthesia. A robotic docking was performed and three arms were positioned in the abdomen. Total operative timing was 45 mins. RESULTS: During the robotic procedure no intraoperative complications were recorded and no drains were applied. The postoperative period was uneventful and the patient was discharged in the first postoperative day. DISCUSSION: Inguinal hernia occurs more frequently in patients with EDS, mainly men. Many surgeons believe that EDS may have a negative effect on the clinical outcome of hernioplasty because of postoperative complication and recurrence rates. Our strategy has been robotic technology to facilitate the surgical approach. CONCLUSION: Robotic technology is feasible and associated with a shorted recovery and better cosmetic results. The endowrist movement of the robotic arms allows wide instrument articulation in a confined space, bypassing the limitis of laparoscopic instruments. In this way, it is possible to realize an accurate dissection of important elements, to reduce operative timing and intraoperative and postoperative complications.
