Background:
Liver parenchymal transection can be associated with significant blood loss and morbidity. We present our initial experience with the Gyrus PlasmaKinetic coagulation device in liver parenchymal resection in both cirrhotic and non-cirrhotic patients.
Methods:
Liver resections were performed in 51 consecutive patients, from 20 July 2005 to 31 August 2007, using the Gyrus PlasmaKinetic coagulator. Requirement for blood transfusions, operating time, duration of hospital stay and major complications were evaluated initially for the group as a whole. Subsequently, the 11 patients with histologically confirmed cirrhosis (nine men, two women, median age 54 years, range 24-74 years) were compared with 40 patients without cirrhosis (25 men, 15 women, median age 57 years, range 24-87 years).
Results:
There were 34 men and 17 women. The median age was 56 (range 24-87 years). There were 48 open procedures and 3 laparoscopic procedures. There were 30 major resections (>2 segments) and 21 minor resections (one to two segments). The overall median operating time was 260 min (range 90-690). Length of stay had a median of 9 days, range 4-50 days. Twenty-one patients (41%) required a blood transfusion. Two biliary leaks were observed in non-cirrhotic patients initially before the settings of the Gyrus device were optimized.
Conclusions:
The Gyrus PlasmaKinetic coagulation device is a novel instrument for hepatic parenchymal transection in liver resection, which can be safely used in cirrhotic and non-cirrhotic patients.
