Use of concentrated human albumin with argon-beam coagulation in laparoscopic partial nephrectomy.

Purpose: Laparoscopic partial nephrectomy (LPN) remains a technically challenging procedure mainly because of the lack of reliable methods of hemostasis. We evaluated the feasibility of using concentrated human albumin with argon-beam coagulation to control hemorrhaging and urinary leakage during LPN.

Materials And Methods: Six domestic swine underwent heparinization, then lower-pole LPN after renal-hilar vascular control had been obtained.

Argon ion beam hemostasis with albumin after liver resection.

Background: Bleeding is common after liver resection and establishing hemostasis with sutures or argon beam coagulation can be difficult. In our laboratory, concentrated albumin applied to the liver surface before argon beam coagulation improves sealing of the resected surface of the liver, including closure of blood vessels and ducts not generally seen with standard argon beam coagulation.

Methods: Domestic swine underwent heparinization, then laparotomy and wedge resection of the left medial segment of the liver, using finger fracture technique.
