title: Evaluation of a vessel-sealing device for laparoscopic granulosa cell tumor removal in standing mares.
abstract: OBJECTIVE
  To describe a laparoscopic technique for granulosa cell tumor removal using a vessel sealing device (LigaSuretrade mark) in standing mares.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Eight mares (8-24 years old; weighing, 406-525 kg).
  
  
  METHODS
  Before surgery, ovarian size and adjacent body wall thickness was determined by ultrasonography. Mares were sedated and after local anesthesia (inverted L and local infiltration), laparoscopic cannulation was performed without insufflation. The mesovarium was anesthetized and the LigaSure instrument applied to the mesovarium for hemostasis and resection to remove the affected ovary. Mares were hospitalized for 24 hours before discharge.
  
  
  RESULTS
  Median ovarian diameter was 10.5 cm (range, 6-14 cm). Median surgery time was 75 minutes (range, 40-180 minutes). Hemostasis was achieved using the LigaSure device in all mares. Median length of the abdominal wall incision made to remove the ovary was 13 cm (range, 5-17 cm); no incisional complications occurred.
  
  
  CONCLUSIONS
  The LigaSure vessel sealing device provided adequate hemostasis for removal of larger neoplastic ovaries in standing mares.
  
  
  CONCLUSIONS
  Concerns of ligature placement can be alleviated by use of the LigaSure device and standing laparoscopic technique provides excellent observation of the surgical field ensuring hemostasis.
