Quick answer: Anal sacculectomy, surgical removal of the anal glands, is recommended for dogs with anal sac tumors (usually apocrine gland adenocarcinoma) or with repeated anal sac infections, impactions, or abscesses that don’t respond to medical care. It’s generally successful, but because the glands sit close to the anal sphincter and nerves, there’s a small risk of complications like temporary fecal incontinence.
Reasons for surgery
- Anal sac adenocarcinoma or other tumors
- Chronic, recurring infections or abscesses
- Frequent impactions despite diet changes and regular expression
Before surgery
- Rectal exam and needle sample of any mass
- Bloodwork, including calcium (anal sac tumors can raise calcium)
- Imaging to check lymph nodes and organs for tumor spread
Recovery
- Cone to prevent licking
- Pain medication and sometimes stool softeners
- Keep the area clean after bowel movements
- Leash walks only for about 2 weeks
Possible complications
- Infection or incision problems
- Straining or discomfort
- Temporary, or rarely permanent, fecal incontinence
Call your vet for swelling, discharge, bleeding, or trouble passing stool.
