Background And Purpose:
Laparoscopic partial nephrectomy raises a number of technical issues, particularly in the control of bleeding. We compared digital compression during hand assistance with a vascular clamp.
Materials And Methods:
Laparoscopic transperitoneal bilateral lower-pole partial nephrectomy was performed on six pigs, with a vascular clamp being used on one side and digital pressure through an Omniport or Lapdisk on the other. The pigs were then euthanized and the kidneys harvested for histologic examination.
Results:
Good hemostasis was obtained regardless of the technique. However, the estimated blood loss was significantly greater with digital compression (96.7 versus 9.6 mL). There were no significant micropathological differences in the kidneys. The surgeons rated suture tying and placement much easier with the purely laparoscopic technique.
Conclusions:
Both techniques are feasible. In experienced hands, the purely laparoscopic technique takes no longer than the hand-assisted technique and is associated with less blood loss, easier suturing, and better cosmesis. However, long-term follow-up is needed before clinical use can be contemplated.
