Plain-English summary
A group of 16 dogs with anal sac tumors underwent a modified surgical procedure to remove the affected glands. Most of the dogs had a type of cancer called apocrine gland anal sac adenocarcinoma. The surgery went smoothly with only one dog experiencing a minor issue afterward that resolved on its own. After an average follow-up of about 286 days, two dogs showed signs of cancer returning, with one needing to be euthanized due to worsening health. Overall, the modified surgery was well-tolerated and had few complications.

Abstract
OBJECTIVE: To describe a modified approach to closed anal sacculectomy and report the short-term outcomes of dogs that underwent the procedure for treatment of neoplasia. ANIMALS: 16 client-owned dogs. PROCEDURES: Medical records of 1 referral hospital were reviewed to identify dogs that underwent modified closed anal sacculectomy for treatment of anal sac neoplasia between January 2018 and September 2020. Data collected included signalment, examination and diagnostic imaging findings, surgical details, intraoperative and postoperative complications, cytologic and histologic findings, adjuvant treatments, duration of follow-up, and short-term outcome. RESULTS: 15 dogs had apocrine gland anal sac adenocarcinoma, and 1 had a collision tumor. No dogs had intraoperative complications; 1 dog had a minor postoperative complication (paraparesis) that resolved. The median duration of postoperative follow-up was 286 days (range, 67 to 777 days). One dog had confirmed local disease recurrence 290 days after surgery, and 1 had suspected local disease recurrence 203 days after surgery and was euthanized because of systemic disease progression. CONCLUSIONS AND CLINICAL RELEVANCE: The modified closed anal sacculectomy was well tolerated in this sample of dogs, with minimal short-term complications. This study provided evidence to justify evaluation of the procedure in a larger number of dogs and assessment of the effects of procedural modifications on postoperative complication rates and time to local recurrence.
