“…A variety of methods have been reported for achieving hemostasis of the ovarian and uterine arteries during laparoscopic and non-laparoscopic ovariectomy and OHE in horses (Santschi et al 1995, Hooper et al 1992, Santschi and Slone 1995, Düsterdieck et al 2003, Rodgerson et al 2002, Ragle and Schneider 1995, Palmer 1993, Rodgerson et al 2001, Bouré et al 1997). In our study, hemostasis of the ovarian pedicle was consistently achieved by single application of a laparoscopic stapling instrument (60 mm / 3.5 mm staples).…”

Conventionally performed equine ovariohysterectomy (OHE) is a technically demanding surgery associated with a high degree of invasiveness and morbidity. Handassisted laparoscopic surgical technique allows introduction of a hand through a portal into the laparoscopic field to facilitate surgical manipulation while maintaining abdominal insufflation and laparoscopic visualization. The purpose of this study was to develop and evaluate a hand-assisted laparoscopic OHE technique for dorsally recumbent horses.The surgical technique was developed in terminal (2 mares) and subsequently evaluated in 6 survival procedures. Mares were fasted 48 hours, anesthetized and positioned in dorsal recumbency for laparoscopic surgery. A hand access device (Omniport) was placed in a caudal midline laparotomy followed by 4 laparoscopic portals. Transection of the ovarian pedicle and broad ligament was achieved using a combination of a laparoscopic stapling instrument, an ultrasonically activated instrument and endoscopic clips. The genital tract was exteriorized through the laparotomy, and the body of the uterus transected and sutured in conventional pattern. Horses were evaluated through postoperative day 14 when a post mortem evaluation was performed.Four mares recuperated well after surgery, 1 mare was euthanized due to bilateral femur fractures sustained during anesthetic recovery and another developed severe pleuropneumonia. At necropsy all but one a bdominal incision was healing routinely. One mare had abscessed along the laparotomy incision and developed visceral adhesions. Uncomplicated healing of transected mesovarial, mesometrial and uterine remnants was observed in all recovered mares.

Twelve clinically healthy, adult male dogs randomly equally divided into two groups (I and II). Animals of both the groups received xylazine-ketamine anesthesia. Laparoscopic bilateral vasectomy was performed in group I, whereas in animals of group II in additition to vasectomy, spermatic artery-vein plexus were clipped with titanium clips at a distance of 1 to 2 cm. Insufflation of abdominal cavity was achieved by CO 2 (2 liter/minute) at 10 mm Hg pressure gradient. Clinical observations revealed no significant changes. Differential leukocyte count (DLC) revealed significant neutrophilia and comparative lymphopenia on 3rd postoperative in both groups. Significant increase (p < 0.05) in plasma alkaline and acid phosphatase level was observed on day 3 postoperatively. Indices of oxidative stress viz lipid peroxidation (LPO), catalase (CAT), superoxide dismutase (SOD), reduced glutathione activity and acute phase protein, ceruloplasmin level in plasma did not revealed any major significant changes but indicated that oxidative stress was more in group II animals. Plasma cortisol level increased significantly (p < 0.01) after operation and testosterone level showed gradual decrease (p > 0.05) up to 7th postoperative day in animals of group II. On the basis of the parameters studied, it can be concluded that capnoperitoneum at 10 mm Hg pressure gradient and CO 2 at the flow rate of 2 liter/minute provides optimum visualization of intra-abdominal organs and found suitable for laparoscopic sterilization in male dogs. The laparoscopic vasectomy alone in male dogs was found comparatively quick, less time consuming and can be successfully applied for mass sterilization program. Oxidative stress in laparoscopic vasectomy (group I) was less as compared to other group.
