Pringle manoeuvre versus selective hepatic vascular exclusion in partial hepatectomy for tumours adjacent to the hepatocaval junction: a randomized comparative study.

OBJECTIVE

To compare the efficacy of selective hepatic vascular exclusion versus Pringle manoeuvre in partial hepatectomy for tumours adjacent to the hepatocaval junction.

METHODS

A randomized comparative trial was carried out. The primary endpoint was intraoperative blood loss. The secondary endpoints were operation time, blood transfusion, postoperative liver function recovery, procedure-related morbidity and in-hospital mortality.

RESULTS

160 patients were randomized into 2 groups: the Pringle manoeuvre group (n = 80) and the selective hepatic vascular exclusion (SHVE) group (n = 80). Intraoperative blood loss and transfusion requirements were significantly less in the SHVE group. In the SHVE group, laceration of hepatic veins happened in 18 patients. Profuse intraoperative blood loss of over 2 L happened in 2 patients but no patient suffered from air embolism because the hepatic veins were controlled. In the Pringle group, the hepatic veins were lacerated in 20 patients, with profuse blood loss of over 2 L in 7 patients and air embolism in 3 patients. The rates of postoperative bleeding, reoperation, liver failure and mortality were significantly higher and the ICU stay and hospital stay were significantly longer in the Pringle group.

CONCLUSIONS

SHVE was more efficacious than Pringle manoeuvre for partial hepatectomy in patients with tumours adjacent to the hepatocaval junction.
