🔍 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

• Bacterial fluorescence was detected in all wounds (17 dogs, 4 cats) using the point-of-care wound imaging device (WID).
• The WID confirmed the presence of clinically relevant wound infection in all evaluated cases at the time of imaging.
• No significant difference was found in bacterial yield or burden between image-guided and non-guided swabs (QBC and PCR; p > 0.05).
• The WID helped guide wound debridement in some cases by localizing areas of fluorescence, especially in necrotic tissue.
• Most infections were polymicrobial and dominated by anaerobes, highlighting the need for anaerobic culture inclusion.
• PCR analysis showed low bacterial DNA yields, often complicated by host DNA contamination, limiting its utility.
• The study did not evaluate sensitivity/specificity of WID, as only fluorescence-positive wounds were included.
• Clinical utility of WID lies in immediate visual confirmation of infection, supporting timely antimicrobial treatment decisions.

🔍 Key Findings

• 39 of 40 checklist items for simulated OVH surgical assessment had good content validity (CVI = 0.81)
• Only 1 of 6 items from the OSATS GRS (respect for tissue) met inclusion criteria (CVI = 0.80)
• Checklist showed strong reliability (G-coefficient = 0.85) for moderate-stakes exams
• Modified OSATS GRS showed acceptable reliability (G-coefficient = 0.79)
• Two raters needed for acceptable reliability in high-stakes exams when using the checklist
• Minimal interrater bias found; variance largely due to interaction among student, rater, and item
• Digital recordings were a reliable method of evaluating surgical performance
• Study supports using checklist over OSATS GRS for assessing preclinical students on simulated models

🔍 Key Findings

140 laparoscopic surgeons surveyed; 37% reported at least one musculoskeletal disorder.
Women had significantly higher odds of reporting WRMD (OR = 2.59, p = .011).
Smaller glove size significantly associated with WRMD (p = .001), shoulder tendonitis (p = .01), and neck strain (p = .001).
Most common injuries: Neck strain (35%), shoulder tendonitis (31%).
WRMD was associated with greater difficulty using:

• Rotating cup biopsy forceps (p < .001)
• Vessel sealing device and endo stapler (especially in those with shoulder injuries)

No significant association with surgeon age, dominant hand, height, weight, or case volume.

🔍 Key Findings:

• Design: Ex vivo study with 24 paired limbs from normal beagle dogs.
• Osteotomy types (3 groups):
  1. 30° uniplanar frontal wedge
  2. Oblique (30° frontal, 15° sagittal)
  3. Single oblique (30° frontal, 15° sagittal, 30° external rotation)
• Comparison: 3D PSG vs Freehand (FH)
• Main Outcomes:
  • PSG accuracy: Mean angular deviation = 2.8° vs 6.4° in FH (p < .001).
  • 84% of PSG osteotomies were within 5° of target vs 50% of FH.
• Significant improvements with PSG in:
  • Group 1 (uniplanar frontal) proximal and distal frontal planes (p < .001, .006)
  • Group 3 (SOO) frontal and sagittal planes (p = .002, .043)
• Time: PSG faster in complex SOO group (84s vs 162s, p < .001); no difference in others.
• No difference in osteotomy location (mm) between methods.
• Clinical relevance: PSG more consistent and accurate, especially for complex cuts.

🔍 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.

🔍 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.

🔍 Key Findings

• TPLO with the contoured saw guide achieved more accurate osteotomy angles for both inclination and torsion in bone models and cadaveric limbs (p < .05).
• Medial cortical damage was significantly lower with the contoured guide (247 vs. 1866 pixels in bone models; p < .001).
• No significant difference in eccentricity (distance between actual and intended osteotomy center) was found between groups.
• Postoperative tibial plateau angle (TPA) was similar between groups (6.4° vs. 7.6°; p = .15), though both were slightly higher than the target of 6°.
• Deviation in medial mechanical proximal tibial angle (mMPTA) showed no significant group difference; valgus deformity occurred in both.
• Osteotomy and device application times were similar between the contoured guide and jig-assisted TPLO.
• The contoured guide eliminated the need for proximal jig pin, potentially reducing intra-articular pin risk.
• The guide's multiple pin fixation system improved stability and alignment, supporting safer osteotomy on curved tibial surfaces.

🔍 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.

🔍 Key Findings

• A novel caudo-medial arthroscopic portal allowed visualization of previously undescribed cartilage lesions on the caudal medial humeral condyle.
• A consistent focal cartilage lesion (HA lesion) was observed in 100% of elbows with HIF (21/21), but in none of the 31 elbows without HIF.
• Lesions varied from indentations to full-thickness cartilage loss, typically elliptical and located just medial to the humeral condyle isthmus.
• A clunk-like sensation and dynamic engagement of the anconeal process into the lesion were observed in 16/21 elbows with HIF during elbow manipulation.
• In 5/21 elbows, engagement of the anconeal process led to observable widening of the HIF line, suggesting dynamic instability.
• Findings support a novel concept of humero-anconeal incongruity as a contributor to the pathogenesis of HIF.
• Spaniel breed was not a confounder—the lesion was only present in elbows with HIF, regardless of breed.
• The study suggests potential for using arthroscopy as a screening tool for early detection of humero-anconeal incongruity and HIF risk.
