New surgical robots on the horizon
In this authoritative lecture, Prof. Barbara Seeliger gives an overview of current and new surgical robotic systems on the horizon and their emerging applications.
Robotically assisted approaches to thoracoabdominal diseases have gained increasing momentum over the last two decades. More than 100 companies offer robotic systems for all surgical disciplines worldwide, and technological progress is driving the adoption of procedures that are challenging with standard instrumentation. Of note, progress in endoluminal surgery will be accelerated with the use of flexible robots, and the treatment of small tumors in the liver and lungs using robotic systems for percutaneous image-guided surgery. Surgical robotic systems as digital interfaces with computer assistance and image guidance will provide connectivity between experts and decision-making support, and enhance training and teaching via the integration of machine learning-based diagnostic systems and advanced telecommunications infrastructures (5G today and 6G tomorrow). As a surgical community, we can continue to shape the future of minimally invasive surgery with clinical trials, research/development projects, and Industry collaborations on an internatinal scale.

Percutaneous transhepatic cholangioscopy and endocanalicular bile duct biopsy
The introduction of the single-operator percutaneous short cholangioscope allows greater maneuverability in the percutaneous and laparoscopic technique. The success rate in different diagnostic and therapeutic scenarios has led to its increased use (1)(2). Among the macroscopic characteristics that we have, benign lesions present a smooth mucosal surface, with ulceration and band stenosis, while malignant lesions are characterized by neovascularization, papillary projections, and tortuous vessels (2)(3).
The importance of cholangioscopy in cases of indeterminate biliary strictures lies in the adequate identification of the causes of biliary strictures, either benign or malignant for adequate therapeutic decision-making (1-4).

Percutaneous transhepatic cholangioscopy and lithotripsy in surgically modified anatomy after bariatric surgery
Cholangioscopy is a method that allows direct visualization of the biliary tree. The main reason for performing endoscopic retrograde cholangiopancreatography (ERCP) is usually choledocholithiasis, and 85 to 90% of bile duct stones are successfully removed during the procedure (1). However, 10 to 15% of the remaining cases involve greater difficulties and may require additional or advanced techniques. In cases of failed ERCP, especially in patients with a surgically altered anatomy, percutaneous transhepatic cholangioscopy (PTC) is used for both diagnosis and treatment of biliary disease. PTC may be considered for several reasons, such as disproportionate stone placement in the distal common bile duct (CBD), patients with a surgically altered gastrointestinal anatomy, biliary strictures, multiple stones, barrel-shaped stones, and difficult-to-access sites when intrahepatic lithiasis or Mirizzi I syndrome is involved (1)(2).
Cholangioscopy-assisted lithotripsy techniques, including electrohydraulic lithotripsy (EHL) and laser lithotripsy, are investigated for their efficacy in breaking up stones. In EHL, the probe is directed to the stone and advanced at least 5mm from the tip of the cholangioscope, bringing it within 1 to 2mm of the stone (3).
As compared to other endoscopic techniques for the biliopancreatic system, cholangioscopy offers a major advantage, as it allows to directly visualize the biliary lumen and mucosa. As a result, cholangioscopy complements ERCP and endoscopic ultrasound (EUS) in the evaluation of complex clinical situations (3)(4).

How to referee a paper - What can you get out of being a referee? (part 1/4)
Courtesy of BJS: This video is part of a series of four given by BJS and BJS Open Editors as a short introductory course on how to referee a clinical paper, focusing on what you can get out of being a referee. Although these are stand-alone videos that can be viewed individually, they are also used as an integral part of a longer taught online course in surgical publishing from the BJS Institute. Details of the courses and other tutorials are available on the BJS Academy website.
Refereeing for a surgical journal is arduous, and comes with specific privileges and responsibilities. However, if you wish others to spend their precious time reviewing your own work, the effort is worthwhile as Miss Grossman, BJS Associate Editor explains in this video.
