HF-Electro-Surgery, Ultrasound-Dissection or Laser for the Laparoscopic Cholecystectomy and for Liver-Wedge-Resection. An Experimental Study in Pigs
laparoscopic wedge-resection of the liver is performed in 6 pigs, in three of these a cholecystectomy is carried out during the same operation. The method of resection chosen was: Monopolar HF-current, ultrasound and laser (Nd:YAG-laser and Holmium:YAG-laser). The least damage to the healthy liver tissue was seen using the Holmium:YAG-laser. Healing (after 18 days) was best when the Holmium:YAG-laser had been used. Cautery was worst in both tissue damage and delayed healing.
