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.

|---|---|---|---|
| 1 | Patients selected for hepatectomy because carriers of hepatocellular carcinoma or colorectal cancer liver metastases invading the middle hepatic vein at caval confluence (last 4 cm). |

| Ultrasound-guided hepatectomy | Procedure | After laparotomy and staging by intraoperative ultrasound (IOUS), anterior surface of the hepatocaval confluence is exposed. Than, compression by means of the surgeon's finger-tip is applied at the MHV caval confluence verifying at color-Doppler IOUS the disappearance of the blood flow in the MHV or its inversion. Then, MHV clamping itself is carried out, and parenchymal sparing resection would be selected if at least one of these 3 findings is confirmed:

| Measure | Description | Time Frame |
|---|---|---|
| The primary outcome measure was the rate of failure of conservative resection, i.e. the rate of patients who received TSs or MHs despite they fitted in the eligibility criteria. | January 2007 |
| Measure | Description | Time Frame |
|---|---|---|
| The secondary outcome measure was the safety of the procedure. For that, we studied morbidity, mortality, amount of blood loss, rate of blood transfusions, and postoperative trend of liver function tests. | January 2007 |
