In Poggi 2024 et al., on laparoscopic resection of pancreatic masses in dogs, what was the maximum tumor size among resected pancreatic masses?
🔍 Key Findings
- Laparoscopic pancreatic mass resection (LPMR) was successfully performed in all 12 dogs, with no conversion to open laparotomy required.
- Median operative time was 69 minutes (range 35–100 min); 11/12 dogs were discharged within 48 hours, and one was discharged after 7 days.
- No major intraoperative complications occurred; minor complications included mild bleeding (2/12) and cannula malfunction (1/12).
- All dogs survived the procedure and were discharged.
- Histopathology confirmed neoplasia in all dogs: 9 insulinomas and 3 pancreatic carcinomas; all tumors were completely excised with clear margins.
- No recurrences were reported; 3 dogs died of unrelated causes, and 9 were still alive at the time of reporting.
- No postoperative hypoglycemia was observed; 1 dog had transient hyperglycemia, and minor complications included vomiting, idiopathic seizures, and pancreatitis, all of which resolved.
- Authors concluded that LPMR is a safe, effective, and minimally invasive alternative to open surgery for selected distal pancreatic masses in dogs.

In Moreira 2024 et al., on predictive equations for TPA correction, which of the following is true regarding the Oxley mCCWO technique?
🔍 Key Findings
- A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
- All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
- TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
- Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
- The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
- Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
- The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
- The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.

In Jeon 2025 et al., on distal femoral shortening, what was the **median femoral shortening ratio** required to achieve prosthesis reduction?
🔍 Key Findings
- Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
- Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
- Bone union was achieved in all cases post-DFSO, indicating good healing potential.
- Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
- One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
- DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
- Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
- DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

In Ibrahim 2022 et al., on scrotal arterial supply, what was concluded regarding the use of scrotal flaps in neutered dogs?
🔍 Key Findings
- Dorsal scrotal arteries, branching from the ventral perineal arteries, are the dominant arterial supply to the scrotum in dogs.
- The ventral scrotal arteries, arising from the external pudendal arteries, perfused only the cranial scrotal border and were inconsistently present or absent in some dogs.
- A scrotal flap based on the dorsal scrotal arteries showed strong perfusion and may be a viable axial pattern flap.
- Perfusion was consistent across fresh and frozen cadavers, showing no difference due to preservation method.
- Poor flap survival (27%) occurred when based on cranial supply alone (i.e., ventral scrotal arteries), confirming importance of preserving caudal supply.
- There are anastomoses between dorsal and ventral scrotal arteries, offering collateral flow but insufficient alone for complete perfusion.
- Scrotal flaps based on the caudal pedicle may be applicable for reconstruction of proximal medial/lateral thigh wounds.
- Proposed flap requires careful preservation of ventral perineal arteries, ideally designed 2.5–3 cm lateral to midline in large dogs.

In Banks 2024 et al., on CCWO technique, what was the observed effect of **osteotomy distalization >7.5 mm**?
🔍 Key Findings
- Oxley's modified CCWO did not achieve the target TPA of 5° in most cases, even with planning.
- Mean planned TPA was 7.6°, higher than target, and consistent across dog sizes.
- Postoperative TPAs were significantly higher in small dogs (median 7°) than in large dogs (median 4.5°).
- Distalization >7.5 mm of the osteotomy from the patellar tendon led to increased under-correction of TPA.
- Only dogs with preoperative TPA >35° achieved post-planning TPAs close to the 5° target.
- Postoperative osteotomy positions were generally more distal than recommended (8.6 mm median).
- Virtual plate fit was appropriate for all dogs at 5 mm or 7.5 mm positions, suggesting no need for excessive distalization.
- Excessive correction leading to negative TPAs occurred in some cases, risking caudal cruciate ligament strain.

In Danielski 2022 et al., on PAUL complications, what was the inter-observer agreement (kappa) for predicting complications from radiographs?
🔍 Key Findings
- Major complications occurred in 25.6% of limbs treated with PAUL, including non-union, implant failure, and infection requiring revision surgery.
- Increased body weight was significantly associated with a higher risk of complications (7% increased risk per additional kg; p = .04).
- Post-operative radiographic assessment was unreliable in predicting complications; inter-observer agreement was poor (kappa ≤ 0.12).
- Expert evaluation of implant or reduction errors had low predictive value (k < 0.2) for postoperative complications.
- Common major complications included non-union (6 limbs), screw breakage, and surgical site infections.
- Implant removal was required in 11.5% of limbs, mostly due to non-union or infection.
- Being a Labrador appeared protective on univariate analysis, but not on multivariate analysis after adjusting for weight.
- Radiographs showing suboptimal plate placement or osteotomy reduction did not reliably correlate with actual complication occurrence.

In Veytsman 2023 et al., on feline insulinoma outcomes, what percentage of cats were euglycemic or hyperglycemic immediately after surgery?
🔍 Key Findings
- Surgical excision of insulinomas resulted in euglycemia or hyperglycemia in 90% of cats immediately post-op.
- 18/20 cats (90%) survived to hospital discharge, with a median survival time of 863 days.
- Younger age, metastasis at surgery, tumor invasion, and lower glucose levels were negative prognostic factors.
- Two cats had stage III disease with metastasis; one lived 413 days post-op, suggesting some benefit to surgery even in advanced disease.
- Postoperative hypoglycemia and seizure activity were associated with poorer outcomes; one cat euthanized due to seizures despite euglycemia.
- Median disease-free interval (DFI) was 1052 days; for cats with metastasis, DFI dropped to 93 days.
- Partial pancreatectomy was performed in 11 cats, nodulectomy in 10, and enucleation in 1; method of resection not linked to outcome.
- Postoperative complications occurred in 25% of cats; most were manageable with supportive care.

In Araos 2024 et al., on helmet CPAP in brachycephalic postoperative dogs, which finding was true regarding SpO₂ following helmet CPAP use?
🔍 Key Findings
- CPAP at 5 cmH₂O via helmet significantly improved PaO₂/FiO₂ ratio in the early postoperative period of brachycephalic dogs, supporting enhanced pulmonary oxygen exchange (p = .04).
- CPAP had no significant effect on SpO₂ (p = .9), PaCO₂ (p = .18), or rectal temperature (p = .5).
- Helmet tolerance decreased over time, with 13 dogs withdrawn for intolerance (9 CPAP, 4 control) and 6 dogs withdrawn for airway compromise (5 control, 1 CPAP).
- CPAP group maintained PaO₂/FiO₂ ratios near or above 400 mmHg, while control dogs showed consistently lower values.
- Authors suggest PaO₂/FiO₂ is a more reliable oxygenation measure than SpO₂ for evaluating postoperative lung function.
- The study found no cases of hyperthermia; temperatures normalized over time in both groups.
- Arterial catheterization failed in several dogs, limiting blood gas analysis to a subset of the population.
- Authors recommend further studies focused on BOAS patients and exploring longer-duration CPAP use to assess impact on critical outcomes like tracheostomy rates or hospitalization.
