Fully robotic-assisted radical resection for HCa is technically achievable in experienced hands and should be limited to highly selective patients. Our current results do not support continued practice of robotic surgery for HCa, until significant technical and instrumental refinements are demonstrated.
Background: Surgery is the main treatment for recurrent retroperitoneal liposarcoma (RPLS). The aim of the present study was to explore the factors associated with blood loss during surgery for recurrent RPLS.Methods: This retrospective study included patients with first recurrence of RPLS who were treated at our hospital between January 2015 and December 2019. Factors associated with intraoperative blood loss were identified by univariate and multivariate logistic regression analyses. Receiver-operating characteristic (ROC) curve analyses were conducted to evaluate whether tumor size and number of tumor-containing abdominal/ pelvic zones were predictive of the need for blood transfusion.
Results:The study included 67 cases. The number of zones containing tumors was 1 in 4 cases (6%), 2 in 36 cases (53.7%), 3 in 14 cases (20.9%), and 4 in 13 cases (19.4%). Tumor size was associated with blood loss >500 mL
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.
