ABSTRACT To evaluate the hemihepatic vascular occlusion with hanging maneuver in hepatectomy.
Ninety-four cases of hepatectomy were analyzed retrospectively. All patients were randomized into 3 groups: Pringle maneuver was applied in Group 1 (n=40), hemihepatic inflow control was Group 2 (n=30) and complete hemihepatic vascular occlusion with hanging maneuver was applied in Group 3 (n=24).The clamping period, operation time, bleeding volume, blood transfusion volume, postoperative recovery of liver function and postoperative complications were compared among three groups.
The average times of clamping in Group 1 was 1.6 +/- 0.7, but only one clamping in Group 2 and 3. There were significant differences among three groups in bleeding volume as well. The postoperative serum ALT and total bilirubin (TBIL) in Group 2 and 3 were significantly lower than those of Group 1.5 patients died of liver failure after operation in Group 1. But liver failure or morbidity wasn't happened in Group 2 and 3. The rates of biliary leakage in Group 1 and 2 were more than that of Group 3. The hospitalization duration of Group 1 was significantly longer than those of Group 2 and 3.
Hemihepatic vascular occlusion with hanging maneuver, which can reduce bleeding volume and enhance the recovery of liver function, is safe and practicable, especially for patients with liver cirrhosis.

    ABSTRACT: To assess the clinical application and usefulness of the liver hanging maneuver (LHM), proposed by Belghiti, for major hepatectomy, including its (1) historical development, (2) usefulness and application and (3) advantages and disadvantages, by reviewing the English literature published during the period 2001-2014. In major hepatic transection via the anterior approach, the deep area of transection around the vena cava is critical with regard to bleeding during right hemi-hepatectomy. Belghiti and other investigators identified avascular spaces that are devoid of short hepatic veins at the front of the vena cava and behind the liver. Forceps can be inserted into this space easily and then maneuvered to lift the liver using hanging tape. This procedure, termed LHM significantly reduces intraoperative blood loss and the transection time during right hemi-hepatectomy. LHM has been used in various anatomical hepatectomy procedures worldwide, including laparoscopic hepatectomy. The use of LHM markedly improves the amount of intraoperative blood loss, operative time and postoperative outcome. We conclude that the application of LHM is an important development in the field of liver surgery, although a further evaluation of its true impact on clinical outcomes is necessary.

    ABSTRACT: Portal triad clamping (PTC) is the most commonly used method of achieving vascular control during liver resection. However, the efficacy and safety of PTC, compared with those of other methods of vascular control, are uncertain. A systematic review was conducted to identify randomized controlled trials (RCTs) comparing PTC with other methods of vascular control during liver resection. Endpoints included in-hospital mortality, need for transfusion, number of complications and length of hospital stay. Meta-analyses were performed using a random-effects model. Ten RCTs were identified; these included a total of 820 patients. No statistically significant differences between PTC and other forms of vascular control in liver resection were demonstrated. There is no evidence, on the basis of this meta-analysis of RCTs, of any difference between PTC and other forms of vascular control in liver resection.

    ABSTRACT: BACKGROUND: Although the safety of liver surgery has improved enormously, hepatic surgery continues to face challenging complications. Therefore, improvements supported by evidence-based guidelines are still required. The conduct of randomized controlled trials in liver surgery using dichotomous outcomes requires a large sample size. The use of surrogate endpoints (SEPs) reduces sample size but SEPs should be validated before use. AIM: The aim of this review was to summarize the SEPs used in hepatic surgery related trials, their definitions and recapitulating the evidence validating their use. METHOD: A systematic computerized literature search in the biomedical database PubMed using the MeSH terms 'hepatectomy' or 'liver resection' or 'liver transection' was conducted. Search was limited to papers written in the English language and published between 1 January 2000 and 1 January 2010. RESULTS: A total of 593 articles met the search terms and 49 articles were included in the final selection. Standard biochemical liver functions tests were the most frequently used SEP (32 of 49 the studies). The used definitions of SEPs varied greatly among the studies. Most studies referred to earlier published material to justify their choice of SEP. However, no validating studies were found. CONCLUSION: Many SEPs are used in liver surgery trials however there is little evidence validating them.
