In Nash 2024 et al., on esophageal pH monitoring, what was the primary method used to calculate upper reference limits for GER parameters?
🔍 Key Findings
- Esophageal pH-monitoring was well tolerated in all 35 nonbrachycephalic dogs, with no major adverse events reported.
- Distal GER occurred in 80% of dogs, but events were typically brief and non-productive; proximal GER occurred in only 39%.
- Upper reference limits for GER were 2.4 events/hour (distal) and 0.4 events/hour (proximal).
- Cumulative acid exposure was minimal: upper limits were 2.3% (distal) and 0% (proximal).
- Comparison with brachycephalic dogs shows significantly higher GER frequency and duration, validating the diagnostic utility of pH monitoring.
- Transnasal probe placement under light anesthesia was safe and less morbid compared to percutaneous or conscious techniques.
- No expelled or productive regurgitation occurred, despite some GER events, indicating efficient esophageal clearance in healthy dogs.
- Diet and fasting duration may affect GER, but these were not controlled variables in this study.

In McNamara 2022 et al., on transoral endoscopic arytenopexy, what was the primary clinical advantage of the TEA technique compared to traditional unilateral arytenoid lateralization (UAL)?
🔍 Key Findings
- TEA significantly increased the rima glottis area (RGA) from a mean of 0.52 cm³ to 0.78 cm³ (p < .0001)
- Mean RGA increased by 157%, equivalent to an 84% estimated decrease in airway resistance
- LEGS (laryngeal epiglottic-glottic seal) remained intact in all cadavers post-procedure, indicating maintained airway protection
- TEA was technically feasible in all 15 cadaveric dogs using a custom endoscopic gag port (EGP)
- TEA avoids cervical dissection, potentially reducing surgical trauma and risks compared to UAL (unilateral arytenoid lateralization)
- Compared to UAL, TEA showed slightly less RGA increase, but greater LEGS preservation, potentially reducing aspiration risk
- No cartilage was included in sutures; arytenopexy involved soft tissue fixation to pharyngeal wall across the piriform recess
- Cadaver model limitations include inability to assess functional outcomes like swallowing and respiratory motion impact

🔍 Key Findings Summary
- Biomechanical study on 14 hindlimbs from Retrievers (cadaveric)
- Three stifle flexion angles tested: 125°, 135°, and 145°
- Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
- Center of force shifted caudally with increasing flexion — especially in medial meniscus
- Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
- Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
- Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

In Song 2024 et al., on CT vs cystoscopy for ectopic ureters in dogs, how did CT perform in detecting extramural ectopic ureters?
🔍 Key Findings
- CT correctly identified ectopic ureters in 91% of dogs, but missed 50% of normal ureters, limiting its negative predictive value.
- Sensitivity for intramural ectopic ureters was 65%, while specificity was 71%, indicating moderate diagnostic performance.
- Sensitivity for extramural ectopic ureters was only 29%, despite a high specificity of 97%.
- CT was inaccurate in predicting ureteral orifice location, with sensitivity ranging from 0% to 76% depending on the site.
- 26% of dogs were misclassified for cystoscopic laser ablation (CLA) eligibility based on CT findings alone.
- Overall CT accuracy for CLA candidacy was 74%, but a significant minority would have been inappropriately treated.
- Multivariate analysis found no predictive factors (e.g., colon distension, body weight) for when CT would be incorrect.
- Authors recommend confirmatory cystoscopy to verify CT findings prior to treatment planning.

In Geier 2022 et al., on smoke evacuation in TPLO, which of the following statements best reflects the effect of electrosurgery on ultrafine particle levels during surgery?
🔍 Key Findings
- Use of smoke evacuators reduced ultrafine particle concentrations by 56.4% during approach to the proximal tibia for TPLO in dogs.
- Mean intraoperative particle concentrations were significantly higher in surgeries without smoke evacuation (1352 ppc vs. 763 ppc, P < .0001).
- Maximum particle concentrations were six times higher without smoke evacuation (62,450 ppc vs. 10,100 ppc, P < .0001).
- Particle counts increased above baseline regardless of evacuator use, confirming electrosurgery contributes substantially to airborne particles.
- Surgeons noted reduced odor and health concerns when using the smoke evacuator, despite initial visibility limitations due to pencil attachment.
- Standard surgical masks do not protect against ultrafine particles, underscoring the importance of smoke mitigation systems.
- The smoke-evacuation unit did not eliminate all ultrafine particles, suggesting optimization (e.g., higher power setting) may be beneficial.
- This is the first clinical veterinary study to measure surgical smoke reduction using evacuators during TPLO.

In Husi 2023 et al., on TPLO vs TPLO-IB biomechanics, which test revealed significantly greater cranial tibial translation after TPLO compared to intact stifles?
🔍 Key Findings
- TPLO alone failed to neutralize rotational instability under tibial pivot compression (TPT), despite a negative TCT.
- TPLO combined with lateral augmentation (TPLO-IB) restored both craniocaudal and rotational stability to near-intact levels.
- Cranial tibial translation was 6× greater after TPLO vs intact stifles when tested with TPT (p < .001).
- No significant difference in cranial tibial translation or internal rotation between intact stifles and TPLO-IB group during TCT, eTPT, or iTPT.
- TPLO-IB did not overconstrain the stifle, avoiding excessive external rotation.
- External tibial rotation (eTPT) was more sensitive than TCT in detecting persistent instability after TPLO.
- Excellent intraobserver reliability for both eTPT and iTPT (ICC > 0.9).
- Study supports intraoperative use of TPT to identify cases needing additional rotational stabilization.

- Septic peritonitis was present in 21/23 sampled dogs, making it a frequent complication.
- Perioperative complications occurred in 21/36 dogs, including aspiration pneumonia, pancreatitis, and acute kidney injury.
- Intraoperative hypotension was common (32/36), often requiring vasopressors or colloids.
- Mortality prior to discharge was 21% (8/38), with deaths related to sepsis, aspiration pneumonia, and multi-organ dysfunction.
- Median survival time was 638 days in dogs surviving to discharge.
- No recurrence of hepatic abscessation was observed in the surviving population.
- E. coli and Clostridium spp. were the most commonly cultured organisms, often as single-agent infections.

In Hoenecke 2025 et al., on radiographic opacity in patella luxation, which variable was found to significantly increase the likelihood of radiographic soft tissue opacity in the stifle?
🔍 Key Findings
- 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
- Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
- Each 1 kg increase in weight increased the odds of opacity by 10%
- Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
- 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
- Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
- Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
- Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

In Gibson 2024 et al., on mediastinoscopy in dogs, which factor was identified as a major **technical limitation** of using a human-designed mediastinoscope?
🔍 Key Findings
- Mediastinoscopy was technically feasible in large-breed canine cadavers using a SILS port and standard laparoscopic instruments.
- The left tracheobronchial lymph node (LTBLN) was successfully retrieved in all cadavers (7/7), while cranial mediastinal lymph nodes were retrieved in only 1/7.
- Postprocedural pleural gas was observed in 4/7 cadavers, likely due to CO₂ insufflation.
- Instrument limitations with a human-designed mediastinoscope led to preference for laparoscopic instruments and SILS port for improved access and visualization.
- Complication rates were low, with only two minor (Grade 1) adverse events (pleural tear and LN rupture).
- Obesity and mediastinal fat were cited as potential challenges to visualization and node retrieval.
- NASA-TLX workload scores were lowest for tracheobronchial nodes, indicating these were the easiest to access.
- The authors concluded this approach may facilitate minimally invasive biopsy or resection of cranial mediastinal masses in live dogs, but clinical trials are needed to validate safety and efficacy.

In Pilot 2022 et al., on closure methods in sternotomy, how did complication severity generally present?
🔍 Key Findings
- Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
- No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
- Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
- Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
- Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
- Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
- Infection rate was low (2.7%), and not significantly different between wire and suture.
- Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.
