In Husi 2023 et al., on TPLO vs TPLO-IB biomechanics, what was the key limitation of the tibial compression test (TCT) after TPLO?
🔍 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.

In Eiger 2024 et al., on NIRFA-ICG in axial flaps, what percentage of CSE flap evaluations led to margin changes based on NIRFA visualization?
🔍 Key Findings
- Caudal superficial epigastric (CSE) flaps were most visible with NIRFA, scoring 4/4 VFP in 97% of evaluations.
- CSE flap margins were altered in 65% of observations after NIRFA, showing the strongest influence on surgical planning.
- Thoracodorsal (THO) and omocervical (OMO) flaps had lower visualization scores, with 60–81% of images scoring below 2.
- Surgeons were 17–25 times more likely to adjust margins for CSE flaps versus OMO or THO based on fluorescence imaging.
- Poor inter-rater agreement was found for OMO (ICC 0.49) and THO (ICC 0.35); CSE had near-perfect agreement, but ICC was low due to uniform high scoring.
- Visualization was affected by flap depth and panniculus, making deeper vessels (OMO, THO) harder to see.
- Surgeons often shortened flap length and reduced flap area when modifying based on NIRFA results.
- Real-time angiosome visualization via NIRFA-ICG may reduce necrosis risk and improve patient-specific APF design.

In David 2024 et al., on single-port cryptorchidectomy, why was a 6 mmHg capnoperitoneum preferred?
🔍 Key Findings
- Single-port laparoscopic-assisted cryptorchidectomy (SP-LAC) was feasible in 13/14 dogs with abdominal cryptorchidism.
- Median surgical time was 17 min for unilateral and 27 min for bilateral cryptorchidectomy.
- All testes were successfully exteriorized through a 15-mm mini-celiotomy in most dogs; only 2 needed slight enlargement.
- One major complication occurred (testicular artery hemorrhage, requiring conversion to open surgery).
- Two minor complications involved trocar-related issues (splenic capsule laceration, capnoretroperitoneum).
- No incisional complications were reported postoperatively; some dogs had mild dermatitis at the clipped site.
- The technique requires only one surgeon and no advanced tools beyond a single-port endoscope.
- Low-pressure capnoperitoneum (6 mmHg) was adequate for visualization in most cases.

In Raleigh 2022 et al., on pericardiectomy complications, which strategy is recommended to minimize VF risk when using electrosurgery?
🔍 Key Findings
- Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
- 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
- Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
- Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
- Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
- Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
- VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
- Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.

In You 2025 et al., on barbed sutures for lung lobectomy, how did the leakage pressure of barbed sutures compare with other techniques?
🔍 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 Chan 2025 et al., on partial cuneiformectomy in BOAS dogs, what was the typical impact on rima glottidis after the procedure?
🔍 Key Findings
- Partial cuneiformectomy (PC) did not increase complication rates compared to multilevel surgery alone (overall complications: PC = 16.3%, non-PC = 19.4%; p = .758).
- Major complication rates were not significantly different (PC = 11.6%, non-PC = 7.4%; p = .482).
- Significant improvement in BOAS grade was observed in dogs undergoing PC (p < .0001).
- BOAS index improved significantly in both groups, with greater median reduction in the PC group (28.5%) than non-PC (20.7%) (p < .0001).
- Low body condition score (BCS <4) was significantly associated with higher complication rates (odds ratio = 0.452; p = .004).
- Hospitalization duration did not differ between groups (median = 1 day; p = .743).
- Mortality was low (3.5%) in the PC group despite more severe airway disease, suggesting the technique is safe even in advanced collapse.
- The technique widened the rima glottidis without damaging surrounding structures, reducing airflow resistance and preserving laryngeal function.

In Kershaw 2025 et al., on PSG vs AD, which surgeon experience level was used to assess PSG utility?
🔍 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.
