Hand-assisted laparoscopic pancreatic resection
No full textThe extent of reported laparoscopic pancreatic resections vary from enucleation to pancreaticoduodenectomy. Nevertheless, most patients with pancreatic disease who require resection are still treated with a traditional approach. Technological advancements in recent years may play an important role for the future diffusion of laparoscopic pancreatectomy. In hand-assisted laparoscopic surgery, the surgeon inserts a hand into the abdomen through a small laparotomy while pneumoperitoneum is maintained, and uses the hand to assist with dissection, palpation and retraction, control of blood vessels, manipulation of organs, and removal of the specimen. We present a review of our experience and of the world literature on hand-assisted laparoscopic pancreatic resection. Based on the first encouraging results, we believe that the hand-assisted technique should allow for substantial advantages to laparoscopic pancreatic surgery in the future
Laparoscopic pancreatic resection
No full textThe extent of reported laparoscopic resections vary from enucleation to pancreaticoduodenectomy. Although initial series have been reported with encouraging results, most patients with pancreatic disease requiring resection are still treated with an open approach. We present a review of our experience and of the world literature on laparoscopic pancreatic resection. Laparoscopic pancreaticoduodenectomy has been attempted in 12 patients with a conversion rate of 33%. Complications occurred in the laparoscopic group. The laparoscopic patients have experienced no benefit in the postoperative recovery and convalescence. Early experience with the hand-assisted approach is promising. Sixty-eight laparoscopic distal pancreatectomies and enucleations have been reported to date. They were 42 distal pancreatectomies and 26 enucleations. Thirteen procedures have been converted to open surgery (19.1%). There was no mortality and the main postoperative complication was pancreatic leak (5 patients, 7.3%). Average hospital stay was 9 days. These results compare favorably with the outcomes after open pancreatic resection. While laparoscopic pancreaticoduodenectomy is not associated with patient benefit and may be accompanied by increased morbidity, laparoscopic distal pancreatectomy and enucleation are safe, carry low morbidity and have encouraging results in terms of postoperative recovery

Evidence-based medicine: Open and laparoscopic bariatric surgery
No full textBackground: The aim of this study was to perform an evidence-based analysis of the literature on open and laparoscopic surgery for morbid obesity.Methods: Human studies on surgery for morbid obesity were conducted. Multiple publications of the same studies, abstracts, and case reports were reviewed. Current Contents, MEDLINE, EMBASE, and Cochrane Library databases were investigated.Results: Open Roux-en-Y gastric by pass (RYGB) for morbidly obese patients and long-limb RYGB for superobese patients are highly effective procedures. Randomized controlled trials comparing malabsorptive procedures with other bariatric operations are needed. The long-term efficacy of adjustable silicone gastric banding (ASGB) still is undetermined because of poor evidence. Laparoscopic RYGB is as safe as its open counterpart, although its long-term results are lacking. Laparoscopic ASGB is less invasive than open ASGB. although its efficacy cannot be determined because of poor evidence. Laparoscopic vertical banded gastroplasty (VBG) is becoming unpopular since the decreasing trend of open VBG. Laparoscopic biliopancreatic diversion with duodenal switch is feasible, but needs further studies.Conclusions: Randomized controlled trials comparing the various laparoscopic operations are strongly needed
Histologic studies of the bypassed stomach after Roux-en-Y gastric bypass in a porcine model
Full text linkLaparoscopic Roux-en-Y gastric bypass (LRYGBP) is highly effective for morbid obesity. However, the long-term effects in the bypassed segments are unknown. The aim of this study is to evaluate gastrin and histologic changes in bypassed segments after LRYGBP
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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 linkWe 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
