Background
Hepatic resections conducted for malignant tumors can be difficult because of the need to create cancer-free margins.
Objectives
To examine the outcome of hepatic resections after the introduction of a Cavitron Ultrasonic Surgical Aspirator (CUSA).
Methods
A retrospective study of patients who underwent hepatic resection by a single surgeon between April 1999 to March 2013.
Results
We included 101 patients with 104 hepatectomies. Most hepatic parenchymal transections were performed using a CUSA under intermittent hepatic inflow occlusion (Pringle maneuver). Thirty-five patients underwent a right hepatectomy, 11 a left hepatectomy, 6 a right hepatectomy and segment I resection, 6 a right lobectomy, and 46 underwent segmentectomies, wedge resections, or other types of hepatic resections. Biliary-enteric reconstruction with a Roux-en-Y limb of the jejunum to a hepatic duct of the hepatic remnant was performed in 28 patients. Operative time was 90–720 min (median 300 min, mean 327 ± 149 min). Operative blood transfusion was 0–17 units (median 3 units, mean 3.9 ± 3.6 units). Twenty-one hepatectomies were conducted without blood transfusion. Thirty-four postoperative complications occurred in 30 patients with a 9% reoperation rate. Perioperative mortality was 6%. Age, operative time, operative blood transfusion, reoperation, and complications were significantly associated with mortality.
Conclusion
Careful preoperative diagnosis and evaluation of patients, faultless surgical techniques, and excellent postoperative care are important to avoid potentially serious postoperative complications and mortality. The CUSA is an effective assisting device during hepatic parenchymal transection with a concomitant Pringle maneuver, apparently reducing operative blood loss.
