🔍 Key Findings

• Buccal transposition flap provided successful closure of large maxillary lip defects in all 5 dogs
• All flaps survived, with 3 dogs experiencing minor complications (e.g., fistulas, dehiscence) that resolved
• Flap vascularization originated from the angularis oris and superior labial arteries, as confirmed via CT angiography
• Excellent cosmetic and functional outcomes were achieved in all cases
• Ex vivo cadaver study validated flap perfusion, showing consistent contrast filling of key arteries
• Oronasal fistulas occurred in 2 dogs at the palatal incision site, likely due to contact with the mandibular canine tooth
• Mandibular canine coronectomy was performed in 2/5 dogs to prevent flap trauma
• Flap design and commissure positioning were customizable, aiding tension relief and improving outcomes

🔍 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.

🔍 Key Findings

• Surgeons with smaller glove sizes experienced more difficulty using laparoscopic instruments, especially endoscopic staplers, cup biopsy forceps, and vessel sealing devices.
• Endoscopic stapler was rated the most difficult instrument, with a median difficulty score of 4/10 and 25% usage difficulty.
• Female surgeons reported significantly more difficulty with several instruments due to smaller glove size.
• Reusable instruments were preferred over disposable ones for all tasks.
• Pistol grips were preferred for grasping/retracting and fine dissection, while axial grips were preferred for suturing/knot tying.
• Articulating handles were consistently associated with increased reported difficulty, especially with scissors and cup biopsy forceps.
• Left-handed surgeons had more difficulty operating endoscopic staplers, suggesting limited design inclusivity.
• Surgeons in academic settings reported more difficulty with laparoscopic maneuvers than those in private practice.

🔍 Key Findings

• Study population: 116 dogs underwent cementless THR; grouped by age:
  • Group A: ≤6 months (n = 27)
  • Group B: >6 to ≤12 months (n = 41)
  • Group C: >12 months (n = 48)
• Overall perioperative complication rate: 31.9% (37/116)
  • Group A: 22.2%
  • Group B: 26.8%
  • Group C: 41.7%
• No significant difference in total complication rate by age (p = .207), though older dogs (Group C) had numerically higher rates.
• Luxation was significantly more common in dogs >12 months:
  • Group C: 14.6% vs. Group A (0%) and Group B (2.4%) → p = .049
• Most common complications: luxation (9.5%) and intraoperative fissure or fracture (9.5%)
• Time under anesthesia and surgery duration were not associated with complication risk (p = .297 and p = .781)
• No infections or aseptic loosening observed during the 8-week follow-up.

🔍 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.

🔍 Key Findings

Design: In vitro study on cadaveric femurs (n=21) with basilar femoral neck fractures stabilized using 2 vs 3 titanium cannulated screws.

Stiffness: Control > 3-screw > 2-screw (674 > 120 > 90 N/mm).

Yield Load: 3-screw (586 N) > 2-screw (303 N); both < intact femur (2692 N).

Displacement: No difference across groups.

Complication: 3-screw technique more demanding; higher risk of cortical perforation, especially with narrow femoral necks.

Failure Mode: Dislodgement of femoral head + screw shaft bending.

Conclusion: 3 screws = stronger construct than 2 screws. Clinical implications need further study.

🔍 Key Findings

• Endoscopic-assisted retrograde catheterization (EARC) and laser sphincterotomy were successful in 18/18 cadavers, demonstrating technical feasibility.
• Intramural common bile duct (ICBD) length ranged from 10 to 21 mm (mean 15.8 mm), with no correlation to body weight (r = 0.06, p = .79).
• Transition from ICBD to extramural duct was accurately identified endoscopically in 88% (16/18); transition was heralded by separation of the submucosal layer.
• Partial lateral perforations occurred in 2/18 dogs, only during early learning phase; no leakage was found on open dissection.
• Laser sphincterotomy preserved the pancreatic duct orifice, aided by protective catheter positioning.
• Compared to open duodenotomy, this technique allows for a smaller incision and less manipulation of the pancreas, which may reduce morbidity.
• No adverse events such as intra-abdominal saline egress or full-thickness perforation occurred, and the technique allowed safe access up to 10 mm from the MDP.
• Cadaveric limitations included absence of biliary pathology and inability to evaluate live complications, but the technique shows promise for future live animal trials.

🔍 Key Findings

• 3D-printed drill guides (3D-GDT) significantly reduced craniocaudal and dorsoventral drilling angle deviation compared to free-hand drilling technique (FHDT), with statistical significance (p < .0001 and p = .01 respectively).
• No sacral corridor breaches occurred with 3D-GDT, whereas FHDT resulted in 20% drill exit incidences (3/15 cases).
• 3D-GDT had lower deviation from optimal drill trajectory at end points in all axes: craniocaudal (1.84 ± 1.6 mm vs. 4.18 ± 2.4 mm), dorsoventral (1.11 ± 1.0 mm vs. 2.4 ± 1.5 mm), and 3D linear (2.47 ± 1.4 mm vs. 5.35 ± 2.2 mm), all statistically significant.
• Strong correlation (r = 0.77) between CT and 3D software measurements validated method reliability.
• 3D guide trajectories showed consistent proximity to the optimal trajectory, especially at drill endpoints, indicating reduced variability in execution.
• 3D-GDT was developed using open-source software and inexpensive materials, supporting future clinical application.
• Major errors in FHDT occurred primarily at the drill endpoint, underscoring the challenge of maintaining optimal angulation during free-hand drilling.
• The sacral corridor was recharacterized as pyramidal (not quadrilateral), with implications for safer implant placement.

🔍 Key Findings

• Augmenting FEESA with two simple interrupted crotch sutures (TCS) or simple continuous crotch suture (SCCS) significantly increased initial leakage pressure (ILP) compared to no suture or a single suture (NCS, SICS).
• SCCS had the highest ILP (47.6 mm Hg), followed by TCS (37.8 mm Hg), SICS (33.0 mm Hg), and NCS (27.1 mm Hg).
• All crotch suture types increased maximal leakage pressure (MLP) compared to no crotch suture.
• Leakage from the crotch occurred most commonly in NCS (67%) and SICS (50%), but only 8% with TCS and 0% with SCCS.
• SCCS was the only technique where leakage never occurred at the crotch site.
• SCCS had the highest MLP (100.6 mm Hg), supporting its use in clinical settings with high-risk patients.
• Intraluminal pressures during leakage in NCS constructs were sometimes below normal physiologic pressures, emphasizing risk of leakage without crotch suture.
• The transverse staple line never leaked in any group, indicating the crotch is the primary weak point.
