In Miller 2024 et al., on leak testing in cooled feline intestine, what explanation was given for higher leak pressures compared to canine data?
🔍 Key Findings
- No difference in initial leak pressure (ILP) or maximum intraluminal pressure (MIP) between cooled (17–29 h) and fresh enterotomy constructs.
- Wall thickness of duodenum and jejunum did not differ between fresh and cooled samples.
- Leak locations (suture holes vs clamp sites) were similar between groups; not statistically different.
- Volume of infusion did not influence ILP or MIP outcomes.
- Mean ILP values: Control = 600 mmHg (maxed), Fresh = 200 mmHg, Cooled = 131 mmHg; CE vs FE difference was not significant.
- Intraluminal diameter was largest in the ileum, followed by jejunum and duodenum.
- Cadaveric intestine cooled ≤29h may be reliably used in ex vivo feline leak pressure studies.
- First report of gross small intestinal lengths by region in cats—useful for resection planning.

In Tobias 2025 et al., on frontal sinus mucoceles, what was concluded about the role of guaifenesin in post-op management of mucoceles?
🔍 Key Findings
- Frontal sinus mucoceles occurred in young dogs, often linked to prior skull trauma by 10 months of age.
- All dogs presented with expansile, fluid-filled lesions causing facial swelling; CT showed multicentric bone erosion, including the frontal bone and cribriform plate.
- Surgical options included frontal sinusotomy with either sinus lining ablation or re-establishment of nasofrontal drainage, with or without stenting.
- Nasofrontal stenting led to long-term resolution in most dogs, although recurrence occurred in 4/8 dogs, requiring revision surgery in 3.
- Complications were minor and included swelling or nasal discharge; no intraoperative complications were reported.
- Histology confirmed sterile mucoceles with neutrophilic inflammation and mucin, and cultures were negative in all cases.
- Guaifenesin was used postoperatively in several cases to reduce mucus viscosity; its benefit is unproven in dogs but may support drainage.

In Grimes 2022 et al., on PDA rupture risks, which factor was **not** found to be significantly associated with rupture risk?
🔍 Key Findings
- Rupture occurred in 7.0% of dogs undergoing surgical PDA ligation (20/285).
- Overall mortality was low (0.4%), with only one death occurring post-rupture.
- Residual flow occurred in 9.4% of dogs; significantly more common in dogs with rupture.
- Residual flow odds were not increased when ligation was successfully performed despite rupture.
- No significant associations between rupture and age, weight, suture size, or dissection technique.
- Jackson-Henderson and intrapericardial techniques were helpful in managing rupture or fibrosis.
- Major complications (non-rupture) were rare (1.4%), including pulmonary artery ligation and cardiac arrest.
- Surgeon preparedness (e.g., hemostatic tools, alternate techniques) was key to successful outcomes.

In de Moya 2023 et al., on FGPP of femoral capital physeal/neck fractures, what was the most common preoperative fracture displacement classification?
🔍 Key Findings
- 11 dogs, 13 fractures (mostly Salter-Harris type I) were repaired with FGPP using Kirschner wires.
- 10/13 fractures achieved satisfactory healing with good limb function at ~43 days median follow-up.
- Major complications occurred in 5 dogs: intra-articular pin placement, implant migration (2), implant failure with nonunion, and malunion.
- 2 dogs presenting >15 days post-injury with radiographic remodeling were poor candidates → higher risk of nonunion/malunion.
- Preoperative displacement was mostly mild (10/13 fractures); these had better outcomes than chronic or severely displaced cases.
- Median surgical time: 60 minutes (range 45–75), all performed percutaneously without conversion to open.
- Elective pin removal was performed in 5 cases; migration occurred with both short and long cut wires.
- Femoral neck resorption (“apple-coring”) was rare (2/10 healed cases) and thought to be less frequent than after ORIF due to reduced vascular disruption.

In Cherzan 2023 et al., on subcutaneous mast cell tumors, what proportion of dogs with lymph node metastases developed tumor recurrence?
🔍 Key Findings
- Local recurrence occurred in 17.8% of dogs, and was associated with significantly decreased survival (551 vs 1722 days, p = .0038).
- Lymph node metastasis occurred in 26.7% of dogs and was significantly associated with shorter disease-free interval (194 vs not reached, p = .0012) and lower survival (551 vs 1722 days, p = .043).
- Mitotic index >7 was significantly associated with higher recurrence (80% vs 22.5%, p = .02), shorter DFI (139 vs not reached days, p < .001), and shorter survival (247 vs 1722 days, p = .05).
- Infiltrative growth pattern was associated with shorter DFI (268 vs 1864 days, p = .011), but not with survival or recurrence.
- Incomplete margins (≤1 mm) were not significantly associated with recurrence (p = .085), but did correlate with shorter DFI (p = .043).
- Chemotherapy or radiation therapy was associated with shorter DFI and survival, likely due to selection bias for more aggressive disease.
- Tumor size >3 cm was associated with decreased survival (p = .031), but not with recurrence or DFI.
- Multinucleation and necrosis were not associated with prognosis outcomes.

🔍 Key Findings
Mortality rate: 36% (12/33)
Cholecystectomy performed: 94% of dogs (31/33)
New significant prognostic factors for survival:
- Hyperbilirubinemia (p = .049) — threshold = 60.5 μmol/L
- Use of vasopressors (p = .002)
- Renal dysfunction postoperatively (p = .008)
- Number of postoperative complications (p = .005)
Multivariate model: Total bilirubin and number of complications best predicted survival
Septic vs nonseptic effusion: No significant difference in survival
Diagnostic imaging: Ultrasound sensitivity for extrahepatic biliary rupture = 38%
Most cultured pathogen: E. coli (80% of septic cases)

In Whitney 2022 et al., on CBLO fixation strength, what conclusion can be drawn about the **use of HCS alone** for CBLO fixation based on biomechanical results?
🔍 Key Findings
- CBLO fixation with both a headless compression screw (HCS) and tension band (TB) showed the highest yield and ultimate loads compared to other configurations
- HCSTB constructs had significantly higher yield load (1212 N) and ultimate load (1388 N) than Plate alone (788 N, 774 N), HCS alone (907 N, 927 N), or TB alone (1016 N, 1076 N)
- No difference in construct stiffness was detected among the four fixation methods tested
- All constructs ultimately failed by bone fracture—location of failure differed by construct type (e.g., through HCS hole or cranial screw hole)
- TB and HCSTB groups showed failure via progressive TB stretching and cranial osteotomy widening, while Plate and HCS failed more abruptly
- All constructs withstood forces exceeding expected quadriceps load in vivo (170–325 N), suggesting all methods can resist physiological loading, but HCSTB provides greater safety margin
- HCS alone was not significantly stronger than Plate or TB alone, questioning its standalone superiority
- Study supports using TB and HCS together for optimal construct strength, but clinical studies are needed to validate implant fatigue, healing, and failure rates

In Espinel Rupérez 2023 et al., in Arthroscopic-assisted hip toggle stabilization in cats, what type of cartilage injury was most commonly observed?
🔍 Key Findings
- 14 joints from 7 cat cadavers underwent AA-HTS successfully.
- Median surgical time: 46.5 min (29–144), including 7 min for arthroscopy and 40 min for toggle placement.
- Intraoperative complications in 5/14 joints: 4 related to femoral tunnel creation, 1 toggle lodging.
- Toggle passage through femoral tunnel was the most challenging step, mildly difficult in 6 joints.
- Cartilage injury occurred in 10 joints, but all were minor (<10% of cartilage area).
- 13 deviations from planned technique were identified (8 major, 5 minor), all involving femoral tunnel placement.
- No neurovascular, intrapelvic, or major periarticular injuries occurred.
- Authors conclude: AA-HTS is feasible in cats, but associated with high rates of minor iatrogenic cartilage damage, intra-op complications, and technique deviations.

🔍 Key Findings
- Algorithm 3 had the highest overall accuracy (95.5%) in diagnosing SSIs from client questionnaires.
- Active surveillance identified 19.4% more SSIs compared to passive surveillance alone.
- SSI rate was 8.22% across 754 surgeries; 33.9% of SSIs required revision surgery.
- Client-based responses were 37.9% more frequent than those from referring veterinarians.
- Deep/implant SSIs could be missed if not associated with visible wound healing problems.
- Two late SSIs (after 90 days) occurred, both linked to implant surgeries.
- Algorithm 1 was the most sensitive (87.1%) but less specific; useful for screening.
- Algorithm 2 had the highest specificity (97.9%); useful as a “rule-in” diagnostic method.
