Objectives:
To describe a standardised subserosal layer dissection technique and evaluate its outcomes in canine laparoscopic cholecystectomy.
Materials And Methods:
Medical records of dogs undergoing laparoscopic cholecystectomy using the standardised subserosal layer dissection technique for the treatment of cholecystolithiasis, cholecystitis, and gall bladder mucocele at a single veterinary hospital from January 2015 to September 2021 were extracted. Operative time, subserosal layer dissection achievement rate, open conversion rate, and complication rate were evaluated.
Results:
Thirty-four dogs were included. The most common preoperative diagnosis was cholecystolithiasis (n=29). Operative time was 190 minutes (range: 110 to 330 minutes). Subserosal layer dissection of more than 90% of the gall bladder bed was achieved in 27 (79%) dogs. Conversion to open surgery was required in three (8.8%) dogs. There were no cases of intraoperative bleeding, bile duct injury, or reoperation.
Clinical Significance:
This study showed that laparoscopic cholecystectomy using the standardised subserosal layer dissection technique could be performed successfully in dogs. Future prospective clinical studies are needed to determine safety and effectiveness of this technique compared to standard techniques.
