Scope Journal of Laparoendoscopic & Advanced Surgical Techniques (JLAST) is the leading international peer-reviewed journal for practicing surgeons who want to keep up with the latest thinking and advanced surgical technologies in laparoscopy, endoscopy, NOTES, and robotics. The Journal is ideally suited to surgeons who are early adopters of new technology and techniques. Recognizing that many new technologies and techniques have significant overlap with several surgical specialties, JLAST is the first journal to focus on these topics both in general and pediatric surgery, and includes other surgical subspecialties such as: urology, gynecologic surgery, thoracic surgery, and more. This pioneering journal has now expanded with the companion videojournal Videoscopy™, available with every subscription.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
