At the time of diagnosis synchronous colorectal cancer, liver metastases (SCRLM) account for 15-25% of patients. If primary tumour and synchronous liver metastases are resectable, good results may be achieved performing surgical treatment incorporated into the chemotherapy regimen. So far, the possibility of simultaneous minimally invasive (MI) surgery for SCRLM has not been extensively investigated. The Italian surgical community has captured the need and undertaken the effort to establish a National Consensus on this topic. Four main areas of interest have been analysed: patients' selection, procedures, techniques, and implementations. To establish consensus, an adapted Delphi method was used through as many reiterative rounds were needed. Systematic literature reviews were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses instructions. The Consensus took place between February 2019 and July 2020. Twenty-six Italian centres participated. Eighteen clinically relevant items were identified. After a total of three Delphi rounds, 30-tree recommendations reached expert consensus establishing the herein presented guidelines. The Italian Consensus on MI surgery for SCRLM indicates possible pathways to optimise the treatment for these patients as consensus papers express a trend that is likely to become shortly a standard procedure for clinical pictures still on debate. As matter of fact, no RCT or relevant case series on simultaneous treatment of SCRLM are available in the literature to suggest guidelines. It remains to be investigated whether the MI technique for the simultaneous treatment of SCRLM maintain the already documented benefit of the two separate surgeries.
Primary leiomyoma of the liver (PLL) is a rare benign tumor occurring in immunosuppressed people. From 1926 less than fifty cases are reported in the scientific literature and about half are in immunocompetent patients. Etiology of this kind of lesion is not yet well known. We report a case of primary hepatic leiomyoma in a 60-year-old immunocompetent woman. The patient presented with lipothymia with unexpected vomiting. She underwent an ultrasound (US), and a computed tomography (CT) scan that revealed the presence of a single, solid lesion about 9 cm located between the S5 and S8 segment of the liver. It showed a well-defined, heterogeneous hypodensity with internal and peripheral enhancement and various central hypoattenuating areas and no wash-out in the portal and the late phases. Because of her symptoms and the risk of malignancy, the patient underwent a surgical liver resection. Histological diagnosis was primary leiomyoma of the liver. The patient had an uneventful recovery and was discharged after 7 days. At 30 months follow-up there were no symptoms and no evidence of disease. Leiomyoma of the liver is a rare benign neoplasm of which clinical symptoms are nonspecific and the exact radiological diagnosis still remains a challenge for radiologists. Etiology is still unclear and usually PLL represents an incidental diagnosis. Surgery plays a primary role not only in the treatment algorithm, but also in the diagnostic workout.
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.
