Robot-assisted surgery fulfils oncologic criteria for D2 dissection and has an oncologic outcome comparable with that of OG. RGR resulted in shorter hospital stays, the loss of less blood and morbidity comparable with that of OG. Randomized clinical trials and longer follow-up are needed to evaluate whether RGR achieves long-term survival rates equivalent to that of open and laparoscopic surgery.
Robot assistance allows optimal access to all liver segments and facilitates parenchymal-sparing surgery also for lesions located in the posterosuperior segments or in contact with main liver vessels.
Robotic LLR is associated with outcomes similar to those obtained with TLLR. However, robotics may facilitate LLR in patients with superior and posterior liver tumors.
Eitel first described omental torsion in 1899, since then, fewer than 250 cases have been reported. Although omental torsion is rarely diagnosed preoperatively, knowledge of this pathology is important to the surgeon because it mimics the common causes of acute surgical abdomen. For this reason, in the absence of diagnosed preexisting abdominal pathology, including cysts, tumors, foci of intra-abdominal inflammation, postsurgical wounds or scarring, and hernial sacs, omental torsion still can represent a surprise. Explorative laparotomy represents the diagnostic and definitive therapeutic procedure. Presently laparoscopy is the first choice procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
