Background:
We prospectively evaluated a novel ultrasound-directed technique of major hepatic resection using transparenchymal application of vascular staplers intending to minimize blood loss, operative time, and hepatic warm ischemia time.
Methods:
Beginning in 1998 many major hepatic resections for hepatic tumors were performed with ultrasound-directed transparenchymal application of vascular linear cutting staplers. An endoscopic flexible neck vascular linear cutting stapler was used for control of the hepatic veins.
Results:
From December 1998 to April 2003, 346 patients undergoing hepatic resection using this technique were identified from a prospective hepatobiliary tumor surgery database. Records were reviewed for blood loss, transfusion requirement, inflow occlusion (Pringle maneuver) time, overall operative time, and perioperative and postoperative complications. The average blood loss for all patients was 396 +/- 28.4 mL. The inflow occlusion time was 13.7 +/- .64 minutes with a total operative time of 140.7 +/- 3.7 minutes. Additional liver-related procedures were performed in 52% of the patients. The overall complication rate was 29.5% with a 90-day mortality rate of 1.4%.
Conclusions:
Ultrasound-directed transparenchymal application of vascular staplers to control inflow and outflow during major liver resection minimizes blood loss, warm ischemia time, and operative time compared to published reports of patients undergoing resection using other techniques.
