Fibrin glue effectiveness and tolerance after elective liver resection: a randomized trial.

BACKGROUND/AIMS: The propensity of fibrin glue to achieve ultimate control of the liver raw surface and its tolerance after hepatic resection, were evaluated by a prospective study. MATERIALS AND METHODS: Seventy seven patients undergoing elective liver resection for benign lesions (n = 35) and malignant lesions (n = 42) including 7 with cirrhosis were studied. Randomization took place only at peritoneal closure and after completion of hemostasis and biliostasis. RESULTS: In the group with fibrin glue (n = 38), a single dose of 5 ml was applied to the liver cut surface. The appearance of the liver margin at abdominal closure was judged as dry in 34/35 (97%) patients with fibrin glue, versus 34/42 (81%) in those without (p = 0.016). Although postoperative morbidity and mortality were not different between the 2 groups, the mean total fluid drainage during the three postoperative days and bilirubin concentration were significantly lower in the group with fibrin glue; respectively 242 +/- 249 ml vs 505 +/- 666 ml and 24 +/- 21 mmoles/l vs 65 +/- 47 mmoles/l. CONCLUSIONS: Our results indicate that fibrin glue application to the hepatic stump after hepatic resection provides effective sealing with good systemic and local compatibility.

Routine use of total hepatic vascular exclusion in major hepatectomy is not necessary.

The prime concert of a hepato-biliary surgeon undertaking liver resection is to minimise blood loss and prevent air embolism through the control of the major vascular structures. Several methods to achieve this are now available and include in particular clamping of the hepatic pedicle and total vascular exclusion. Both techniques are detailed as well as their benefits and drawbacks. For conventional liver resections, total vascular exclusion has no advantage over clamping of the hepatic pedicle in preventing blood loss and is associated with additional morbidity. This technique should be selectively used in patients with tumours involving major hepatic veins or the inferior vena cava.

Vascular occlusion techniques for liver resections.

Prevention of intraoperative blood loss during liver resection is of prime concern. Intraoperative blood loss has indeed repeatedly been shown to adversely influence the short-term prognosis of patients undergoing liver resection. There is in addition evidence that it could be associated with an increased risk; of recurrence in patients operated for an hepato-biliary malignancy through impairment of the patient's immune response. The prime concern of the hepato-biliary surgeon is to minimize blood loss through the control of the major vascular structures this may be achieved in several ways that range from segmental portal control to total hepatic vascular occlusion. The type of vascular occlusion should be selected according to the indication and in particular location of the tumour and presence of an associated underlying liver disease, the patient's cardiovascular status and the experience of the operator. Aim of the authors is to describe the various types of vascular control as well as their benefits and drawbacks so as to use the most appropriate technique according, to each patient' requirements.
