In Kuvaldina 2023 et al., on endoscopic axillary lymphadenectomy, what structure must be carefully preserved during dissection?
🔍 Key Findings
- Endoscopic excisional biopsy of axillary lymph nodes was successfully performed in cadavers and clinical dogs with minimal complications.
- The technique used a SILS port and CO₂ insufflation through a small incision between the latissimus dorsi and superficial pectorals.
- In 4 cadavers (6 limbs), mean time to remove axillary nodes was 33 minutes, and single nodes were found in 5/6 limbs.
- In 3 clinical dogs, the procedure was successful in 2 cases; 1 required conversion to open surgery due to difficulty manipulating the node.
- Accessory axillary nodes were successfully excised when present, located adherent to deep latissimus dorsi.
- No cases developed lymphedema, pneumothorax, or major complications postoperatively.
- Subjective benefits included better visualization, reduced dissection, and less postoperative morbidity than open techniques.
- Study suggests MIS lymphadenectomy may improve staging accuracy and reduce complications, though larger studies are needed.

In Kuvaldina 2023 et al., in Minimally invasive axillary lymphadenectomy in dogs, which of the following best describes postoperative morbidity in the 3 clinical patients?
🔍 Key Findings
- A minimally invasive endoscopic technique was successfully developed for excisional biopsy of axillary lymph nodes in dogs.
- The procedure was performed on 4 cadavers (6 limbs) and 3 clinical patients, with no major complications reported.
- Mean cadaveric time: accessory axillary node 5.1 min; axillary node 33 min. One limb had a double axillary node.
- In clinical cases, 2/3 were completed endoscopically; one required conversion to open due to node elevation difficulty.
- Surgical times in clinical cases ranged from 35 to 58 minutes, depending on node accessibility and number.
- Postoperative morbidity was minimal: no lymphedema, minor seroma or lameness resolved quickly.
- The SILS port approach enabled effective access, though precise placement was critical to visualization.
- This is the first reported veterinary endoscopic technique for axillary lymphadenectomy; potential for improved staging and reduced morbidity.

In Gutbrod 2024 et al., on feline tibial stabilization, how did the 2.4 mm LCP + 1.0 mm pin construct perform compared to others?
🔍 Key Findings
- 2.4 mm LCP with a 1.6 mm IM pin had the highest axial stiffness and yield strength among the tested constructs.
- Axial stiffness was significantly higher in the 2.4 mm LCP + 1.6 mm IM pin group compared to 2.7 mm LCP alone (p = .013).
- No significant difference in torsional stiffness was found among groups.
- 2.4 mm LCP + 1.0 mm pin had the lowest stiffness and failure load, underperforming both other constructs.
- All constructs failed via valgus bending, consistent with clinical observations in feline tibial fractures.
- A 1.6 mm pin (~50% canal fill) resulted in superior construct performance vs. 1.0 mm (~30% fill).
- Group 2 (2.4 LCP + 1.6 mm pin) outperformed the 2.7 mm LCP alone in stiffness, despite using a smaller plate.
- Plate–rod constructs may better preserve periosteal blood supply and support minimally invasive stabilization strategies.

In Haine 2022 et al., on outcomes in canine limb tumors, what was the overall R1 rate following planned narrow excision for soft tissue sarcomas?
🔍 Key Findings
- Fewer R1 margins (tumor on ink) were achieved in mast cell tumors (MCTs) when using 6–10 mm lateral margins versus 0–5 mm (7% vs. 55%; _P_ = .049).
- For soft tissue sarcomas (STSs), no benefit was seen in margin completeness between 0–5 mm vs. 6–10 mm lateral margins (41% vs. 43% R1).
- Overall R1 rates were 26% for MCTs and 42% for STSs following PNE.
- R scheme (“tumor on ink” = R1) had better interobserver agreement (83%) compared to ≤1 mm margin criteria (68% agreement).
- Complication rate was moderate (26%), but no surgeries required revision.
- Local recurrence/metastasis occurred in 14% of dogs, with 60% of those having R1 margins.
- Adjunctive therapy was considered clinically indicated in 46% of 0–5 mm margin cases vs. 24% of 6–10 mm cases.
- Histologic grade and tumor size were not predictive of margin completeness.

In Logothetou 2024 et al., on SPF complications, which anatomic site for SPF reconstruction was associated with the fewest complications?
🔍 Key Findings
- Complication rate for subdermal plexus flaps (SPFs) in dogs was 53.6%.
- Skin staples had a numerically higher complication rate (72.2%) than sutures (49.3%), but not statistically significant due to small sample size.
- Most common complication was wound dehiscence (35%), followed by seroma (14%) and wound discharge (14%).
- Increased body weight was significantly associated with higher complication risk (OR = 1.056 per kg; p = .029).
- Advancement flaps were associated with a lower incidence of complications on univariable analysis (p < .001).
- Head region flap closures had fewer complications, while proximal pelvic limb closures had the highest complication rate.
- Age was a risk factor—each additional year increased odds of complications (OR = 1.019; p = .004).
- Closure technique did not significantly influence complication severity, though staple use was numerically worse.

In Levine 2025 et al., on thoracoscopic pericardiectomy, which approach may offer benefit when paired with thoracic duct ligation (TDL)?
🔍 Key Findings
Study design: Randomized cadaveric comparison (n=20 dogs; ILR vs PDR)
Approaches:
- ILR = Intercostal in Left Lateral Recumbency (no OLV required)
- PDR = Paraxiphoid in Dorsal Recumbency (traditional)
Outcomes:
- Pericardiectomy time was shorter for ILR (p = .045)
- Pericardial fragment size was significantly larger in PDR group (p = .004; 23.21 cm² difference)
- Visibility and cardiac exposure were superior in PDR group
Feasibility:
- ILR approach was consistently successful in achieving partial pericardiectomy
- Bilateral ventilation was adequate; no need for OLV
Clinical relevance:
- ILR may improve efficiency when paired with TDL
- PDR remains preferable for cases requiring maximal pericardial resection

In Muroi 2025 et al., on refracture risk, what factor was significantly associated with refracture in dogs **retaining plates**?
🔍 Key Findings
- Refracture occurred in 5.5% of limbs, with higher incidence in the plate removal group (12.5%) vs. non-removal (3.5%).
- In the non-plate removal group, refractures occurred at the most distal screw site, linked to greater screw position change during growth (OR 1.79, p=0.04).
- Screw-to-bone diameter ratio (SBDR) >0.4 was a significant risk factor for refracture in the plate retention group.
- In the plate removal group, refractures occurred at the original fracture site, associated with lower pixel value ratio (bone mineral density) and reduced radial thickness.
- Implant-induced osteoporosis (IIO) beneath the plate likely contributed to refracture risk after plate removal.
- Younger age at fracture (<6 months) was associated with higher refracture risk due to ongoing radial growth and shifting screw position.
- No significant association was found between refracture and plate type (locking vs conventional), fixation method, or ulnar union.
- Recommendations include careful SBDR sizing, motion restriction, and cautious plate removal decisions in growing dogs.

🔍 Key Findings
- CT localization of liver masses was more accurate by division (88%) than by lobe (74.3%)
- Inter-radiologist agreement was excellent for division (kappa up to 0.885) and only moderate–good for lobe
- Quadrate and right lateral lobes had significantly lower localization accuracy compared to left lateral or medial lobes
- CT localization of the left division was most accurate (90.1%) compared to central (77.1%) and right (88.3%)
- Portal and hepatic venous phases were equally helpful for localization (each ~30–38% usefulness)
- No significant associations found between histopathologic diagnosis and localization accuracy
- Lobe-level CT localization should be interpreted with caution, especially for the quadrate and right lateral lobes
- Radiologist experience likely influenced accuracy, with the most experienced radiologist performing best

In Evers 2023 et al., on needle arthroscopy for meniscal tears, what was the mean duration of needle arthroscopy procedures?
🔍 Key Findings
- Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for diagnosing medial meniscal tears in dogs with CCLR.
- NA missed 1 medial and 1 lateral meniscal tear, both nondisplaced and stable.
- Visibility of all meniscal horns was significantly lower with NA compared to standard arthroscopy (SA) (P < .005 for all horns).
- Probing the caudal horn of the lateral meniscus was significantly more difficult with NA (P = .0017), though medial horn probing was similar.
- Mean NA procedure time was 8 ± 3 minutes, significantly shorter than SA (15 ± 9 min, P = .0041).
- No increase in lameness observed after NA, indicating minimal procedural morbidity.
- NA was performed under sedation in most dogs, though 10/26 required additional chemical restraint or short anesthesia.
- NA was most accurate for displaced vertical longitudinal tears, with all 14 correctly identified; one stable tear and a lateral tear were missed.

🔍 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.
