Meta-analysis reveals 14.4% complication rate for laparoscopic ovariohysterectomy in female dogs, indicating significant risk factors.

The research aimed to determine the prevalence and risk factors of complications in laparoscopic ovariectomy and ovariohysterectomy in dogs.
Conducted a meta-analysis of studies published from January 2000 to October 2025.
Analyzed 43 studies with 45 analytical arms involving 2,548 female dogs.
Evaluated intraoperative and postoperative complications and the number of laparoscopic ports used.
Pooled prevalence of total complications was 14.4% with high heterogeneity (I²=87.1%).
For laparoscopic ovariectomy, the prevalence was 10.6%, while for laparoscopic ovariohysterectomy, it was 31.6%.
Odds of complications were significantly lower for laparoscopic ovariectomy compared to laparoscopic ovariohysterectomy (OR=0.23).

Çortu et al. (2026) studied this question.
