In Hertel 2025 et al., on portal venotomy for insulinoma, what was the dog's outcome one year postoperatively?
🔍 Key Findings
- Portal venotomy enabled successful en bloc resection of a pancreatic insulinoma and associated thrombus in the portal vein, a novel approach in veterinary literature.
- Temporary portal vein occlusion (15 min) was well tolerated, causing only transient small intestinal congestion without lasting hemodynamic compromise.
- No intraoperative hemorrhage occurred following vascular isolation and venotomy repair with 5–0 polypropylene in a simple continuous pattern.
- Postoperative complications were minimal, with only moderate pancreatitis managed medically and no portal hypertension observed on follow-up imaging.
- Histopathology confirmed insulinoma, with no initial metastasis; CT at 6 months revealed hepatic and peritoneal metastases but no local recurrence at the venotomy site.
- Portal vein luminal stenosis occurred post-repair but was clinically insignificant.
- Advanced CT imaging and 3D printed modeling significantly enhanced surgical planning and anatomical assessment.
- Surgical excision achieved good short-term outcomes, and the dog was alive and euglycemic one year later despite metastatic disease.

In Knudsen 2024 et al., on CTA diagnosis, what was the observed **negative likelihood ratio (NLR)** of CTA for meniscal lesion detection in second readings?
🔍 Key Findings
- Multidetector CTA had high sensitivity (up to 100%) and specificity (up to 96%) for detecting medial meniscal tears in dogs.
- Observer experience significantly influenced diagnostic accuracy, with more experienced observers showing higher agreement and better performance.
- Training effect was evident, as less experienced observers improved between first and second readings.
- Positive likelihood ratios ≥4.6 and negative likelihood ratios ≤0.08 were observed, suggesting CTA is clinically useful for confirming or ruling out meniscal injury.
- CTA allowed identification of full and partial thickness lesions, with good visualization in sagittal, transverse, and frontal reconstructions.
- Approximately 90% of menisci were correctly classified in second readings.
- No adverse reactions were noted from the contrast injection; sedation was used instead of general anesthesia.
- CTA was less invasive and potentially more cost-effective compared to arthroscopy, especially in settings without MRI access.

In Farrugia 2025 et al., on BODPUO location effects, which variable most significantly predicted the postoperative change in proximal ulna angle?
🔍 Key Findings
- Proximal BODPUOs (closer to 26–28% of ulna length) resulted in greater increases in proximal ulna tilt postoperatively (up to 18°).
- Distal osteotomies (closer to 48–49%) yielded minimal change in ulna angle.
- Strong linear relationship between osteotomy location and change in angle; correlation coefficient = 0.73.
- Initial proximal ulna angle (IPUA) influences results—angles closer to 90° yielded greater changes.
- Craniocaudal osteotomy angle had minimal impact on tilt change after adjusting for location.
- Osteotomy length had no significant effect on change in angle.
- Prediction intervals showed wide individual variation in outcomes, especially with more proximal osteotomies.
- No increase in complications was associated with more proximal osteotomies, contrary to past assumptions.

In Shetler 2022 et al., on radial head OCD, what confirmed the diagnosis of osteochondritis dissecans in this case?
🔍 Key Findings
- Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
- Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
- Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
- Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
- Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
- Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
- Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
- The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.

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 Saitoh 2025 et al., on CTS stabilization, which group of dogs all returned to work after CTS stabilization?
🔍 Key Findings
Study population: 12 dogs with medial or lateral tarsocrural joint instability (TCI), including 5 working farm dogs.
Procedure: Temporary immobilization using a calcaneotibial screw (CTS) combined with external coaptation (EC).
Stabilization techniques:
- 3 dogs = primary ligamentous repair
- 8 dogs = synthetic ligament reconstruction
- 2 dogs = malleolar fracture repair
Follow-up: Median 31 months (range 4–66); 10 owners completed outcome survey.
Outcomes:
- All 10 dogs had improved or resolved lameness.
- All 5 farm dogs returned to work (most at full or substantial capacity).
- Complication rate: 4 distinct events in 3 dogs (1 major = CTS breakage; 3 minor = bandage-related soft tissue injuries).
Conclusion: CTS + EC provided effective immobilization with low complication rate, and functional outcomes were favorable even in active dogs.

In Niida 2024 et al., on surgical residents and TPLO time, how much longer did residents take compared to faculty surgeons (FS)?
🔍 Key Findings
- Resident involvement significantly increased TPLO surgery duration compared to cases performed by faculty surgeons (FS)-only. Residents required 54% more surgery time (GLSM, 153 min) than FS-only cases (GLSM, 99 min), representing a 1.54-fold increase.
- The study did not report on short-term complication rates. No conclusions can be drawn from this source regarding complications between resident and faculty groups.
- Bone plate contouring was not evaluated. The source does not provide data regarding contouring frequency or its comparison between groups.
- Surgery duration significantly decreased after the first year of residency, but remained stable between second- and third-year residents. This was largely due to shorter tibial osteotomy durations, while arthroscopy times remained unchanged across residency years.
- Meniscal treatment was performed in 80% of cases, and it was associated with increased surgical duration, but the study did not compare the frequency of medial meniscal release between resident and faculty cases.
- The study did not evaluate osteotomy healing or revision surgery. Cases requiring immediate reoperation were excluded.
- Bone union outcomes were not assessed at 8 weeks or any other time point.
- The study concludes that resident participation significantly prolongs surgical time, but no data are provided regarding the effect on short-term clinical outcomes.

In Barrett 2023 et al., on complication grading systems, what was the **main limitation** in applying the aCD system to veterinary cases?
🔍 Key Findings
- Cook system had good reliability across all cases (ICC = 0.848), even when complications, sequelae, and failure-to-cure were included.
- aCD system had excellent reliability when excluding sequelae/failure-to-cure cases (ICC = 0.975) but only moderate reliability when including them (ICC = 0.620).
- Majority of complications (60–63%) were graded as Grade 3 in the aCD system, corresponding to surgical or anesthetic intervention.
- Cook system classified most cases (78–81%) as major complications.
- Assessors had difficulty distinguishing sequelae from Grade 1 complications, and failure-to-cure from Grades 1–2, reducing aCD reliability.
- The aCD system offers more resolution (5 grades vs. 3) and less subjectivity through objective definitions.
- Novel terminology (e.g., sequelae, failure to cure) in the aCD system may hinder its uptake without proper training.
- Reclassifying expected events (e.g., swelling, bruising) as sequelae could significantly reduce reported complication rates in other studies.

In Hawker 2024 et al., on checklist attitudes, what was a leading barrier cited for noncompletion of SSCs?
🔍 Key Findings
- 67.9% of respondents reported using SSCs, with most indicating frequent use (64% used in every surgery).
- 78.7% agreed SSCs reduce complications, and 89.6% believed SSCs improve communication.
- Respondents not using SSCs were more likely to view them as a waste of time (p < .001).
- Forgetfulness (39.6%) and time constraints (36.5%) were leading reasons for checklist noncompletion.
- Only 23.3% had SSC training during surgical residency, with newer diplomates more likely to have had exposure (p < .001).
- Key strategies to improve uptake included: staff feedback modifications (67.9%), formal designation of initiator (48.6%), and training (52.2%).
- Surgeons and OR staff were most commonly identified as noncompliant team members.
- SSC use was more frequent in small animal practices, and mandating SSCs by management was favored but not always effective alone.
