Tobias et al: Perineal hernia repair in dorsal recumbency in 23 dogs: Description of technique, complications, and outcome
Veterinary Surgery 5, 2022

🔍 Key Findings

  • Perineal hernia repair was feasible in dorsal recumbency in all 23 dogs, allowing simultaneous perineal and abdominal procedures without repositioning.
  • Internal obturator muscle transposition (IOMT) was successfully performed in 22 dogs, with tendon transection facilitating improved muscle elevation.
  • Complication rate was 60.9% in-hospital and 47.8% post-discharge, mostly minor (e.g., swelling, drainage), with infection suspected in 4 dogs (17.4%).
  • Recurrence rate was 19% overall, but significantly higher in dogs with prior hernia repairs (50% vs 5.9%; p = 0.053).
  • Dogs without prior repairs or organ pexies had no recurrences (p = 0.035), suggesting primary repairs without preexisting interventions fare better.
  • Castration and adjunctive abdominal procedures (e.g., colopexy, cystopexy) were often performed concurrently (18/23 dogs).
  • Colopexy did not prevent recurrence, although it aided in surgical visualization during perineal repair.
  • Dorsal positioning allowed simultaneous access to the abdomen and perineum, improving surgical efficiency without added complications.

Multiple Choice Questions on this study

In Tobias 2022 et al., on perineal hernia repair positioning, what was the recurrence rate in dogs with prior hernia repair on the same side?

A. 5.9%
B. 10%
C. 19%
D. 36.4%
E. 50%

Answer: 50%

Explanation: Recurrence was highest (50%) in dogs that had previous hernia repair on the same side.
In Tobias 2022 et al., on perineal hernia repair positioning, which technique was used in 22 out of 23 dogs?

A. Semitendinosus muscle transposition
B. Porcine submucosa mesh
C. Internal obturator muscle transposition
D. Autologous fascia lata implant
E. Polypropylene mesh

Answer: Internal obturator muscle transposition

Explanation: IOMT was used in 22/23 dogs; it was the primary technique in this cohort.
In Tobias 2022 et al., on perineal hernia repair positioning, which statement best reflects the outcome of colopexy?

A. It was always effective at preventing recurrence
B. It reduced recurrence in previously unoperated dogs
C. It improved visualization during hernia reduction
D. It increased complication rates
E. It was associated with urinary incontinence

Answer: It improved visualization during hernia reduction

Explanation: Colopexy helped facilitate visualization but did not prevent recurrence.
In Tobias 2022 et al., on perineal hernia repair positioning, what postoperative complication occurred most frequently during hospitalization?

A. Prosthetic failure
B. Perineal swelling
C. Urinary tract infection
D. Bladder herniation
E. Wound dehiscence

Answer: Perineal swelling

Explanation: Perineal swelling was the most common in-hospital complication (5 cases).
In Tobias 2022 et al., on perineal hernia repair positioning, which surgical advantage did dorsal recumbency provide?

A. Reduced intraoperative bleeding
B. Improved cosmetic outcome of the incision
C. Simultaneous access to abdomen and perineum
D. Decreased anesthesia time
E. Lower recurrence rates

Answer: Simultaneous access to abdomen and perineum

Explanation: Dorsal positioning allowed concurrent perineal and abdominal procedures without needing repositioning.
