In You 2025 et al., on barbed sutures for lung lobectomy, what was the most common site of air leakage in the barbed suture group?
🔍 Key Findings
- Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
- No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
- Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
- Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
- Staplers remained fastest, with mean ligation time of 2.4 minutes.
- No knot failure or suture breakage was observed in barbed or traditional suture groups.
- Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
- Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

In Griffin 2025 et al., on sentinel lymph mapping, which method provided surgical planning advantages before dissection?
🔍 Key Findings
- Six dogs with thyroid carcinoma underwent preoperative CT lymphography (CTL) and intraoperative sentinel lymph node (SLN) mapping using methylene blue (MB) and indocyanine green (ICG) with near-infrared (NIR) imaging.
- SLNs were successfully identified in all dogs (6/6).
- SLNs included medial retropharyngeal, cranial deep cervical, and superficial cervical nodes.
- Metastatic carcinoma was found in 3/12 SLNs, in 2/6 dogs.
- Some discordance occurred between CTL and intraoperative SLN findings (partial match in 3/6).
- Protocol modifications (e.g., reduced dye volume, post-exposure injection) improved localization and minimized dye diffusion.
- No intraoperative complications or adverse events occurred.
- Study supports further investigation of combined SLN mapping techniques in canine thyroid cancer.

In Schneider 2025 et al., on axillary LN extirpation, what percentage of removed axillary lymph nodes contained tumor-related pathology?
🔍 Key Findings
- Lateral approach to ALN extirpation was successful in 100% of cases (44 dogs, 48 ALNs) with consistent anatomical landmarks (costochondral junction of rib 1 and caudal scapular edge).
- Median time for ALN removal was 16.6 minutes, highlighting a fast and efficient dissection method.
- No intraoperative complications were recorded (e.g., hemorrhage or inability to find the lymph node).
- Postoperative complications occurred in 18% of cases, including seromas (n=2), wound dehiscence (n=4), lameness (n=1), and discomfort (n=1).
- Histopathology revealed 56% of ALNs had tumor-related pathology, including overt metastases, early metastasis (HN2), or premetastatic changes (HN1).
- Normal-sized ALNs (<2 cm) still harbored metastases in 22% of cases, emphasizing the unreliability of size as a staging criterion.
- False negatives in cytology occurred in 4 cases, underlining the limitations of cytologic evaluation for staging.
- The technique was reproducible without specialized tools, suggesting wide applicability in general and referral practice.

In Petazzoni 2022 et al., on DPO in older dogs, what was the most notable change in femoral head coverage after surgery?
🔍 Key Findings
- DPO improved joint congruity and clinical signs in dogs ≥10 months old with minimal osteoarthritis.
- Median Norberg angle increased by 21.8% 1 year postoperatively (from 87° to 106°; p < .01).
- Femoral head coverage increased significantly, with PC rising 66.7% and LHC by 162.5% at 1 year (p < .01).
- No significant change in pelvic canal width postoperatively, suggesting pelvic conformation was preserved.
- All ilial osteotomies healed with complete osseous bridging by 8 weeks; 7/11 pubic osteotomies achieved full healing.
- No intraoperative or postoperative complications were reported, including implant failure.
- Locking plates and additional ventral plating were used in select cases and may have contributed to implant stability.
- DPO may be extended to older dogs with suitable hip morphology and minimal OA, expanding traditional age criteria.

In Sandoval 2024 et al., on lung lobectomy technique outcomes, how many lobectomies per group are needed for a superiority study comparing SLL and stapler?
🔍 Key Findings
- Intra- and postoperative complications occurred only in stapled lobectomies, but the difference was not statistically significant (intra: p = .069, post: p = .112).
- Intraoperative hemorrhage was the most common complication (11.8%), followed by air leakage (2%).
- All self-ligating loop (SLL) lobectomies had zero complications (n=18), though the sample was small.
- Postoperative complications included 4 catastrophic events (cardiopulmonary arrest), all in stapled cases.
- Lung lobectomy technique was not associated with duration of chest tube use, hospitalization, or survival (p > .05).
- 94.3% of patients survived to discharge (82/87).
- SLLs are lower-cost and may be more feasible for thoracoscopic/minimally invasive approaches due to smaller port size (5mm vs. 12mm for staplers).
- A future superiority study would need ≥103 lobectomies per group to assess differences in complication rates.

In Kershaw 2025 et al., on PSG vs AD, what was the most significant benefit of using a patient-specific guide (PSG) during transcondylar screw (TCS) placement in dogs?
🔍 Key Findings
- 3D-printed patient-specific guides (PSGs) significantly improved accuracy of drill hole entry (p < 0.001) and exit (p = 0.044) compared to commercial aiming devices (AD).
- Zero joint penetrations occurred with PSGs, whereas 3 of 7 AD-guided screws were predicted to penetrate the joint (p = 0.19).
- Variance in exit point and drill angle was significantly lower in PSG group, suggesting more consistent results.
- One PSG case failed due to improper guide seating, but this was corrected with improved soft tissue clearance.
- PSGs enabled safer trajectories despite use by novice surgeons, emphasizing their value in less experienced hands.
- Drill holes placed with ADs deviated more cranially and distally, increasing the risk of articular violation.
- Use of PSGs allowed for tighter clustering of drill trajectories, especially in the cranial–caudal axis.
- Subjective feedback favored PSGs for ease of use and ergonomic design, despite requiring slightly larger incisions.

In Whitney 2022 et al., on CBLO fixation strength, which variable was found to have **no significant effect** on construct stiffness, yield load, or ultimate load in CBLO testing?
🔍 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 Longo 2023 et al., on CT trochlear measurements, which statement is TRUE regarding the clinical utility of FTGA?
🔍 Key Findings
- Dogs with MPL had significantly shallower femoral trochlear grooves compared to controls, based on CT-measured femoral trochlear groove angle (FTGA).
- FTGA >134° in small breeds (SB) and >128° in medium/large breeds (MLB) were associated with MPL and can serve as surgical thresholds for considering trochleoplasty.
- FTA and FTRIA measurements were less reliable, showing lower sensitivity/specificity than FTGA.
- Inter-rater reliability for FTGA was excellent (ICC > 0.9), supporting its use in clinical decision-making.
- FTGA differed significantly between SB and MLB dogs, suggesting anatomical variation influences MPL predisposition.
- Dogs with MPL but with FTGA below threshold may not benefit from trochleoplasty, supporting individualized surgical planning.
- CT provides more precise and reproducible evaluation of trochlear morphology than radiography or ultrasound.
- The study introduces a CT protocol using P25 and P50 reference points for consistent FTGA measurement.
