Principal contest of laparoscopic castration is achieving optimal endo-hemostasis of the testicular blood vessels. The present study was designed to describe and compare two endo-hemostatic techniques; electrocauterization and clipping in lateral recumbent horses. The study was performed on eight horses admitted for routine castration. Multiple technical difficulties associate bipolar electrocauterization technique such as impairment of visibility of the surgical field due to engendered smoke, the necessity for frequent cycles of coagulation-transection, bleeding from improperly coagulated vessels and tissue carbonizing. These difficulties increased the surgical time and decreased the feasibility of the procedure. Meanwhile, Clipping endo-hemostatic technique especially Multi-Fire clipping is advisable as a safe alternative procedure for elective laparoscopic castration in lateral recumbency. It has the superior hemostatic capabilities coupled with simple technical feasibility; two ports, one surgeon and scored the minimal operative time and no intra-operative complications.
