Single-port video-assisted ovariohysterectomy in bitches: retrospective study of 20 cases/Ovario-histerectomia video-assistida com unico portal em cadelas: estudo retrospectivo de 20 casos

The aim of the present study was to evaluate retrospectively the first 20 cases of single-port video-assisted ovariohysterectomy (SPVA-OSH) performed by an inexperienced surgeon. Twenty bitches submitted to SPVA-OSH were assessed. A 10mm operative rigid endoscope with one 5 mm working channel and bipolar coagulation was used. The trocar was positioned in the prepubic area of the abdomen. Surgical time and complication rates were assessed descriptively. Mean surgical time was of 22.95 ± 5.17 minutes. Mild or moderate complications were present in six (30%) out of 20 bitches that were operated. The first five surgical procedures spent more time to be performed than the others. The longest transoperative momentum time of execution was spent in the approach to the left and right ovarian pedicles. The complications were: mild or moderate hemorrhage from one of the ovarian pedicles in four bitches (20%) and severe hemorrhage due to accidental puncture of the spleen with Veress needle in two animals (10%). SPVA-OSH was performed in bitches by an inexperienced surgeon, without severe complications.
