In Scheuermann 2024 et al., on 3D-printed reduction guides for tibial fractures, how was virtual surgical planning efficiency affected by case number?
🔍 Key Findings
- The study was a prospective clinical trial evaluating the efficacy of a three-dimensional (3D)-printed, patient-specific reduction system for aligning diaphyseal tibial fractures stabilized using minimally invasive plate osteosynthesis (MIPO) in fifteen client-owned dogs.
- Virtual surgical planning (VSP) and fabrication were feasible within a clinically relevant timeframe, with a mean of 50.7 hours. Surgical efficiency improved with experience.
- Pin-guide placement was accurate, with median translational discrepancies of 2.7 mm (proximal) and 2.9 mm (distal), and angular discrepancies highest in the axial plane.
- The proximal guide was easier to apply (median Likert score: 8) than the distal guide (median: 6).
- The 3D-printed system enabled near-anatomic reduction in 87% of cases and acceptable reduction in the remaining 13%; no unacceptable reductions occurred.
- Postoperative alignment and tibial length were well-restored, with all dogs within 5° or 5 mm of contralateral measurements.
- Temporary circular fixation was occasionally used to assist reduction and improve alignment.
- Precontoured plates fit easily, with a median Likert score of 9; total surgical time was shorter than conventional MIPO at the institution.
- The study lacked a control group but builds on prior cadaveric feasibility work.

In Matz 2022 et al., on stapler size comparison, which stapler group had the highest mean initial leak pressure (ILP)?
🔍 Key Findings
- No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
- All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
- Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
- Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
- No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
- Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
- One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
- Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.

In Danielski 2025 et al., on PUO complication reduction, what was the **most common major complication** observed?
🔍 Key Findings
- Combined intramedullary (IM) pin and rhBMP-2 use resulted in a low complication rate (7.4%) after proximal ulnar osteotomy (PUO).
- Major complications occurred in 5.3% of cases (4 infections, 1 pin breakage with ulnar tilt requiring revision).
- Minor complications occurred in 2.1% of cases (seroma, delayed union).
- No cases of non-union were observed; 98.9% of limbs achieved radiographic healing by 6 weeks.
- IM pin breakage was noted in 11.8% of limbs but did not affect healing outcomes.
- Chondrodystrophic breeds made up 64.8% of the cohort and tolerated the procedure well.
- Compared to prior studies, complication rates were substantially reduced with this technique (prior major: 13.9%; this study: 5.3%).
- The use of rhBMP-2 likely enhanced early bone healing and provided biologic support, particularly important in breeds at higher risk of complications.

In Chik 2024 et al., on cholangioscopy feasibility, what was the most distal biliary region consistently visualized using the 3.8 mm disposable flexible endoscope?
🔍 Key Findings
- Open transcholecystic cholangioscopy was feasible using a 3.8 mm disposable flexible endoscope in all 8 canine cadavers.
- Visualization was consistently achieved up to the junction of the hepatic ducts, common bile duct, and cystic duct.
- Advancement past the junction was limited by the endoscope diameter (3.8 mm) and anatomical flexure.
- The 1.9 mm flexible ureteroscope could visualize the entire biliary tree, including the major duodenal papilla, in a large dog (43.8 kg).
- Endoscopic tools (e.g., 3 Fr grasping forceps) could be passed through the working channel only after removing the irrigation line.
- Standard biopsy forceps were incompatible with the disposable endoscope's 1.2 mm working channel.
- Cadaver study showed no rupture, but clinical extrapolation is limited due to lack of diseased tissue.
- Disposable endoscope setup cost (~$6,100) was significantly lower than traditional endoscopy systems (~$75,000–100,000), improving accessibility.

In Miller 2024 et al., on leak testing in cooled feline intestine, where did most leaks initiate in both groups?
🔍 Key Findings
- No difference in initial leak pressure (ILP) or maximum intraluminal pressure (MIP) between cooled (17–29 h) and fresh enterotomy constructs.
- Wall thickness of duodenum and jejunum did not differ between fresh and cooled samples.
- Leak locations (suture holes vs clamp sites) were similar between groups; not statistically different.
- Volume of infusion did not influence ILP or MIP outcomes.
- Mean ILP values: Control = 600 mmHg (maxed), Fresh = 200 mmHg, Cooled = 131 mmHg; CE vs FE difference was not significant.
- Intraluminal diameter was largest in the ileum, followed by jejunum and duodenum.
- Cadaveric intestine cooled ≤29h may be reliably used in ex vivo feline leak pressure studies.
- First report of gross small intestinal lengths by region in cats—useful for resection planning.

In Monti 2025 et al., on lymph node fluorescence imaging, which lymph node group was most frequently identified and removed using NIRF-guided laparoscopic surgery?
🔍 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.

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.
