Davis et al: Modified closed sacculectomy in 50 dogs with non‐neoplastic anal sac disease
Veterinary Surgery 2, 2025

🔍 Key Findings

50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):

  • Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
  • Grade 2 (medical treatment needed): 2/43 (5%)
  • Grade 3B (revision surgery): 2/43 (5%)

93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.

Multiple Choice Questions on this study

In Davis 2025 et al., on modified anal sacculectomy, which feature differentiates the technique from prior closed methods?

A. Packing the anal sac with gel
B. Dissecting over the sac fundus
C. Using electrocautery through rectal wall
D. Following duct path to sac
E. Leaving duct in place

Answer: Following duct path to sac

Explanation: The technique involves tracking the duct for immediate sac identification, avoiding the need for packing or fundus dissection.
In Davis 2025 et al., on modified anal sacculectomy, what was the only intraoperative complication observed?

A. Hemorrhage from sac wall
B. Perineal nerve transection
C. Anal sac perforation
D. Rectal wall tear
E. Anal stricture

Answer: Anal sac perforation

Explanation: Only intraoperative complication was anal sac perforation, occurring in 5 dogs (10%), with no associated sequelae.
In Davis 2025 et al., on modified anal sacculectomy, what was the resolution rate of minor postoperative complications?

A. 50%
B. 70%
C. 85%
D. 93%
E. 100%

Answer: 93%

Explanation: 13 of 14 dogs with grade 1 complications resolved by 2-week follow-up (93%).
In Davis 2025 et al., on modified anal sacculectomy, what was the most common complication grade reported postoperatively?

A. Grade 4
B. Grade 3B
C. Grade 2
D. Grade 1
E. Grade 0

Answer: Grade 1

Explanation: Grade 1 complications (minor, self-limiting signs like scooting or inappropriate defecation) occurred in 32% of dogs.
In Davis 2025 et al., on modified anal sacculectomy, what proportion of grade 3B complications resolved with revision surgery?

A. 0%
B. 25%
C. 50%
D. 75%
E. 100%

Answer: 100%

Explanation: Both grade 3B cases (5%) resolved fully after revision surgery within 2 weeks.
