A retrospective study published in the BSAVA's Journal of Small Animal Practice suggests that complications are less common after a laparoscopic than an open ovariectomy1.

For the study, Tim Charlesworth, an RCVS Specialist in Small Animal Surgery from Eastcott Referrals (pictured right), analysed 260 cases where dogs had undergone laparoscopic or open surgical ovariectomy between January 2013 and January 2018 by the same team of similarly experienced surgeons using standard practice anaesthetic, theatre and perioperative protocols. Complications were then compared between the two groups. 

44% (46) of the dogs that underwent open ovariectomy developed a complication, compared to 20% (31) of those that underwent laparoscopic ovariectomy.

Whilst the authors acknowledge the limitations of a retrospective study and emphasise that confirmation requires a randomised trial, they say that when considered alongside previously demonstrated improved postoperative comfort and earlier return to normal function, laparoscopy could be considered preferable for ovariectomy in dogs.
