A simple technique for procuring liver allografts while protecting arterial vessels
No full textArterial injury remains a common complication during organ procurement, with negative effects on postoperative morbidity and graft survival. We describe a simple technique that helps surgeons avoid vascular injuries during isolated liver procurement (without pancreas). This simple technique has been used in 200 liver procurements without any arterial injuries
The protocol of low-impact laparoscopic cholecystectomy. the combination of mini-laparoscopy and low-pressure pneumoperitoneum
No full textLow-impact laparoscopic (LIL) cholecystectomy is an innovative surgical protocol that combines the use of mini-laparoscopic instruments (3-mm ports) under a low- and stable-pressure pneumoperitoneum (8 mmHg), with the aim of minimizing the surgical invasiveness and the risks related to CO2insufflation on the peritoneal environment. In day-surgery settings, LIL may contribute to increase the surgical success due to several potential benefits in terms of postoperative pain intensity and time to full recovery. In 14 consecutive patients requiring cholecystectomy for uncomplicated cholelithiasis, LIL was carried out uneventfully. No conversion, intra-operative or postoperative complications occurred. All patients were discharged the same day of surgery. Postoperative pain was well tolerated with no need of prolonged opioid therapy. Technical aspects and indications for LIL cholecystectomy are detailed
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
Personal Experience With 150 Isolated Procurements of Liver Allografts: Two Different Techniques
No full textLearning curve for laparoscopic cholecystectomy has not been defined: A systematic review
No full textBackground: Laparoscopic cholecystectomy is one of the most performed surgeries worldwide but its learning curve is still unclear. Methods: A systematic review was conducted according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Two independent reviewers searched the literature in a systematic manner through online databases, including Medline, Scopus, Embase, and Google Scholar. Human studies investigating the learning curve of laparoscopic cholecystectomy were included. The Newcastle–Ottawa scale for cohort studies and the GRADE scale were used for the quality assessment of the selected articles. Results: Nine cohort studies published between 1991 and 2020 were included. All studies showed a great heterogeneity among the considered variables. Seven articles (77.7%) assessed intraoperative variables only, without considering patient's characteristics, operator's experience, and grade of gallbladder inflammation. Only five articles (55%) provided a precise cut-off value to see proficiency in the learning curve, ranging from 13 to 200 laparoscopic cholecystectomies. Conclusions: The lack of clear guidelines when evaluating the learning curve in surgery, probably contributed to the divergent data and heterogeneous results among the studies. The development of guidelines for the investigation and reporting of a surgical learning curve would be helpful to obtain more objective and reliable data especially for common operation such as laparoscopic cholecystectomy
Lower GI endoscopy in polyps and polyposis
No full textIntestinal polyps can be classified by their shape or histological aspect and they can be isolated, multiple, or belonging to polyposis syndromes. The most common isolated intestinal polyps in children are the juvenile (hamartomatous) polyps which represent more than 90% of cases. Several polyposis syndromes exist and they are characterized by the presence of numerous polyps in gastrointestinal tract with an increased risk of developing malignancy compared to general population. These syndromes can be divided into hereditary and non-hereditary forms. Clinically, the intestinal polyposis can cause several symptoms such as changes in intestinal habits, abdominal pain, bloody stools, weight loss, and extraintestinal manifestations including benign and malignant neoplasms in various organs such as thyroid, central nervous system, breast, and genital tract. Because of this systemic involvement, the approach to polyposis must include a series of endoscopic, radiological, clinical, genetic and laboratory probes to diagnose early mucosal lesions and establish appropriate follow-up and therapies
