Abstract

Unlabelled: In order to avoid laparotomy in patients with superficially and/or anatomically favourably located liver lesions, the feasibility of laparoscopic liver resection using an aqua jet was evaluated in 6 pigs. For this purpose a commercially available water jet dissector was adapted for laparoscopic use and modified to a multifunctional device providing aqua jet, suction and cautery. To improve laparoscopic vision during jet activity a hydrolaparoscope was used. The left lateral lobe was resected using clips for haemostasis only.

Results: All animals (34-55 kg, average 41 kg) survived the procedure. The blood loss at operation consisted of 225 ml (50-600 ml), the haematocrit 3.3% (1-8%). No bleeding or other complications were encountered postoperatively. The average weight of the specimens was 201 g (120-289 g).

Conclusions: Laparoscopic liver resection using an aqua jet is feasible. Safe haemostasis can be achieved with clips if the vessels are entirely freed with the jet before clipping.

多模态水射流解剖器——用于腹腔镜肝脏手术的技术。
未标记:为了避免浅表和/或解剖位置有利的肝脏病变患者开腹手术,在6头猪中评估了使用水射流进行腹腔镜肝切除术的可行性。为此,一种市售的水射流解剖器适合腹腔镜使用,并被改造成一种多功能装置,提供水射流、吸力和烧灼。为了改善射流活动期间的腹腔镜视力,使用了水腹腔镜。切除左外侧叶,用夹子止血。结果:所有动物(34 ~ 55公斤,平均41公斤)均成活。术中出血量225 ml (50 ~ 600 ml),红细胞压积3.3%(1 ~ 8%)。术后无出血及其他并发症。标本平均重量201 g (120 ~ 289 g)。结论:采用水射流进行腹腔镜肝切除术是可行的。如果在夹钳之前血管完全被喷射器释放,则可以使用夹钳实现安全止血。
