Major hepatectomies have not negligible morbidity and mortality. However, when tumors invade middle hepatic vein (MHV) at caval confluence major surgery is usually recommended. Ultrasound-guided hepatectomy might allow conservative approaches. We prospectively check its feasibility in a series of patients carriers of tumors invading the MHV at the caval confluence.
Major hepatectomies have not negligible morbidity and mortality. However, when tumors invade middle hepatic vein (MHV) at caval confluence trisectionectomy (TS) is generally performed, and central hepatectomy or mesohepatectomy (MH) (Segments 4, 5 and 8), is considered by some authors to be the conservative alternative to the previously cited approach. Between these two surgical interventions there is not, up to now, any evidence that one of them should be clearly preferred; anyway both are mojor resections. We previously reported that a surgical approach based on ultrasound-guided hepatectomy might minimize the need for major resection, whose rates of morbidity and mortality are not negligible. This policy could be useful also for disclosing new, more conservative, and better tolerated approaches for tumors invading the MHV at caval confluence in alternative to MH and TS. This study analyses the feasibility, safety and effectiveness of ultrasound-guided resections applied to these patients enrolled prospectively from a cohort of consecutive patients who undergo hepatectomy for tumors.
