Background and objectives: Availability of hi-tech surgical devices has elaborated the technique of parenchymal transection during hepatectomy from classic crushing clamp technique 1,2 to a combination of an ultrasonic dissection with special type of cautery 3,4. We have developed a new technique to resect hepatic parenchyma using an ultrasonic surgical aspirator in association with a monopolar floating ball. This combination has been utilized in 42 liver resections.
Methods: A retrospective analysis of perioperative mortality, length of hospitalization, and blood transfusion during surgery in two patient groups who underwent liver resection was carried out. We divided the patient population into Group A (42 patients), who underwent the new technique, and Group B (107 patients), who experienced the crushing clamp technique. A second analysis was performed, where we divided the same patient population group in Group 1 with age less than 65, and Group 2 including patients older than 65 years.
Results: We found that the new technique reduced length of stay, procedure length, and use of perioperative blood. We determined that the two age groups performed similarly in comparison to LOS, length of procedure, blood use, and complications.
Conclusion: This enforces the fact that the elderly can receive such surgical treatment without hesitation.
