In Scheuermann 2023 et al., on femoral MIPO alignment, which reduction system resulted in longer surgical times?
🔍 Key Findings
- Precontoured plates using 3D-printed femoral models achieved near-anatomic alignment in all cadaver limbs.
- Fracture reduction system (FRS) required significantly fewer fluoroscopy images than intramedullary pin (IMP) methods (7 vs 26, P = .001).
- Despite longer surgical time (43 vs 29 minutes, P = .011), FRS showed equally accurate or better alignment compared to IMP.
- Femoral length, frontal, sagittal, and axial alignment were all within near-anatomic thresholds (<10 mm or <5° deviation) in both groups.
- FRS was associated with more consistent length maintenance, with IMP showing a median shortening of 2.3 mm (P = .03).
- Axial plane deviation was statistically different in the FRS group (P = .04), but still clinically acceptable.
- Study highlights potential for custom 3D-printed guides to reduce radiation exposure and improve precision in MIPO procedures.
- Authors caution that FRS was time-consuming and cumbersome, suggesting design refinements needed for clinical use.

In Alvarez-Sanchez 2023 et al., on SLN mapping in canine MCT, what was the histologic metastasis rate (HN2 or HN3) in excised lymph nodes?
🔍 Key Findings
- Combined ICTL and NIRF detected the same SLN in 80% of cases; each method alone missed sentinel lymph nodes in some dogs.
- ICLT failed in 5% of dogs, while NIRF failed in 20%; combined use resulted in only 5% failure in SLN detection.
- Metastatic lymph nodes were detected in 95% of dogs, despite most tumors being low or intermediate grade (95%).
- 27 of 41 nodes (65.8%) were histologically metastatic (HN2 or HN3), many of which would have been missed using ALN alone.
- ALN matched the SLN in only 45% of cases with ICTL and 30% with NIRF, supporting the need for SLN mapping.
- ICLT and NIRF were complementary, often identifying different SLN, with some only fluorescent or enhanced in one modality.
- Subcutaneous MCT had higher metastatic rates (7/8 dogs) than previously reported, challenging older assumptions about benign behavior.
- Removing both ALN and SLN (from both methods) improved detection of metastasis to 85–95%, reducing risk of understaging.

In Winston 2023 et al., on LES-AS surgery outcomes, which preoperative treatment was discontinued postoperatively in all dogs?
🔍 Key Findings
- Modified Heller myotomy with Dor fundoplication improved vomiting/regurgitation scores by 180%, QoL by 100%, and owner-perceived body weight by 63% (P < .05).
- 6 of 9 dogs with postoperative VFSS showed objective improvement in gastric filling scores; others remained stable.
- Oral sildenafil was discontinued postoperatively in all dogs, indicating surgical success comparable to medical management.
- 12 of 13 dogs survived to discharge; one dog was euthanized due to aspiration pneumonia postoperatively.
- 50% of dogs experienced gastrostomy tube complications, higher than reported in previous literature.
- Most complications were gastrostomy-tube related, with some requiring surgical correction (e.g., tube migration, leakage).
- Feeding strategies (Bailey chair, elevated bowls) and food consistency (gruel/liquid) remained essential postoperatively to control regurgitation.
- 9 of 11 owners would opt for the surgery again; those who wouldn’t cited risk or lack of efficacy.

In Dobberstein 2024 et al., on liver biopsy forceps, which biopsy technique caused the most tissue crush artifact?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Karydas 2025 et al., on follow-up radiography, which factor had the highest odds ratio for triggering a postoperative plan change?
🔍 Key Findings
139 immature dogs with humeral condylar fractures (HCF) reviewed retrospectively.
Postoperative plan changed in 17% (23/139) of cases.
Key risk factors for plan change:
- Owner concerns (OR: 7.6)
- Analgesic use at follow-up (OR: 7.9)
- Lameness (OR: 5.9)
- Abnormal clinical exam (OR: 44.8)
- Radiographic abnormalities (OR: 51.9)
No plan changes were based solely on radiographs when clinical signs were absent.
Supracondylar K-wire migration noted in 3.5% of dogs without affecting the clinical plan.
Authors conclude that routine follow-up radiographs offer limited value without concurrent clinical indicators.

In Planchamp 2022 et al., on imaging-based AAI diagnosis, what was the cutoff value of the VCI in dogs imaged in flexion?
🔍 Key Findings
- Ventral Compression Index (VCI) ≥0.16 (extension) or ≥0.2 (flexion) was diagnostic for AAI with 100% sensitivity and >94% specificity
- VCI had the highest diagnostic accuracy among all measured variables (AUC > 0.99)
- C1-C2 overlap ≤2.7 mm (extension) or ≤1.8 mm (flexion) also diagnostic for AAI (sensitivity 84–96%, specificity 81–90%)
- C1-C2 angle ≥176.9° (extension) or ≥187.4° (flexion) had high sensitivity and specificity (~95%)
- Basion-dens interval ≥5.9 mm (extension) or ≥3.0 mm (flexion) provided moderate diagnostic accuracy
- Cranial translation ratio (CTR) ≥0.18 classified dogs as potentially unstable (sensitivity 90%, specificity 78%)
- VCI ≥0.23 reliably differentiated AAI from potentially unstable cases (sensitivity 94%, specificity 94%)
- DALR ≤0.24 had high specificity (100%) but low sensitivity for AAI diagnosis

In Mazdarani 2025 et al., on simulated muscle loading, what was the clinical significance of using hip mobility in limb press models?
🔍 Key Findings
- Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
- Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
- Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
- Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
- Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
- Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
- Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
- The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

In Duffy 2022 et al., on barbed suture oversew, which repair method demonstrated the **shortest completion time** during oversew of the transverse staple line?
🔍 Key Findings
- Oversewing the transverse staple line using barbed suture showed no difference in initial (ILP) or maximum leakage pressure (MLP) compared to monofilament suture (p = .439 and .644).
- Barbed suture repairs were ~18% faster (25 seconds faster; p < .001) than monofilament suture.
- No difference was found between unidirectional and bidirectional barbed sutures in leakage resistance or repair time (p = .697).
- Mean ILP and MLP were significantly higher in control jejunal segments (6.6x and 5.1x greater respectively; p < .001).
- Leakage consistently occurred at the crotch of the FEESA in all oversew groups (>80%), not the staple line.
- All oversewn techniques leaked at supraphysiologic pressures, indicating clinical safety against in vivo leakage.
- No leakage was observed from barbed suture holes, addressing concerns of tissue trauma due to barb design.
- The study supports barbed suture as a viable alternative to conventional monofilament suture for FEESA oversew in dogs.

- 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 Monti 2025 et al., on lymph node fluorescence imaging, what was the most common intraoperative complication encountered during NIRF-ICG guided laparoscopic ISLN excision?
🔍 Key Findings
- Laparoscopic ISLN removal using NIRF-ICG was feasible in 89% of dogs (16/18), demonstrating high procedural success with minimal invasiveness.
- Median laparoscopic dissection time was only 12 minutes, suggesting efficiency of the NIRF-guided approach.
- No postoperative complications were observed, and intraoperative complications occurred in only 2 dogs (11.1%), both requiring conversion to open surgery.
- Metastatic disease was confirmed in 48% of patients (12/25 nodes), including cases where LNs appeared normal in size, highlighting the value of histologic evaluation.
- NIRF-ICG enabled precise identification of small and mildly enlarged nodes, which are often missed during traditional imaging or palpation.
- Fluorescent dye leakage following LN capsule rupture limited visibility and required surgical conversion, indicating a key limitation of the technique.
- ICG signal was occasionally absent in metastatic LNs, likely due to lymphatic rerouting or obstruction, underscoring limitations in SLN identification.
- The lateral approach allowed consistent access to ipsilateral MILN, IILN, and sacral LNs, though contralateral nodes were inaccessible with this method.
