🔍 Key Findings

• Histologic agreement between 3 mm and 5 mm biopsies was 90%, with a Gwet's AC1 of 0.81 (p < .0001).
• 5 mm biopsies yielded significantly more portal triads and lobules than 3 mm samples (p = .0003 and p < .0001).
• Crush artifacts were significantly higher in 3 mm samples (p = .035), though fragmentation scores were similar (p = .935).
• Both forceps produced adequate samples for histopathology, copper quantification, and bacterial culture.
• No hemorrhage requiring intervention occurred, and both sizes were deemed safe and minimally invasive.
• Surface area ≥40 mm² strongly predicted ≥11 portal triads, a desirable threshold for reliable histopathology.
• Use of 3 mm instruments was easier in small dogs (<12 kg), but more challenging in larger dogs due to shaft length.
• Clinical diagnoses were unaffected by forceps size, even in the one discordant histologic pair.

🔍 Key Findings

• All FEESA configurations leaked at lower pressures than intact segments, confirming reduced integrity vs. native tissue.
• FEESA with 3-row transverse staples (3V/3T or 2V/3T) had significantly higher leak pressures than 2-row configurations.
• 3V/3T configuration had the highest ILP (69.88 ± 21.23 mmHg) among all groups, significantly greater than 2V/2T and 3V/2T (P < .001).
• Leakage consistently occurred at the transverse staple line (not vertical), regardless of configuration.
• No significant difference in maximum intraluminal pressure (MIP) between FEESA groups.
• All FEESA constructs withstood intraluminal pressures >25 mmHg, exceeding normal physiological jejunal pressure in dogs.
• No leaks occurred from the vertical staple line, highlighting it as a more robust closure site.
• Third staple row in transverse line may be a viable alternative to suture oversew, pending further clinical evaluation.

🔍 Key Findings Summary

• Normative ultrashort echo time (UTE) MRI T2* values were established for:
  • Patellar ligament (PL): T2*L = 4.65 ms
  • Cranial cruciate ligament (CrCL): T2*L = 5.99 ms
  • Caudal cruciate ligament (CdCL): T2*L = 7.06 ms
• Statistically significant differences in T2*L values were found between:
  • PL vs. CrCL (p = 0.03)
  • PL vs. CdCL (p = 0.0097)
  • CrCL vs. CdCL (p = 0.03)
• No significant differences in short T2* (T2*S) values across ligaments.
• Study highlights potential of UTE MRI to detect early ligament changes even without physical instability.
• May guide early diagnosis in partial CrCL rupture where standard MRI is limited.

🔍 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

🔍 Key Findings Summary

• HIF typically originates 57° caudal to the supratrochlear foramen and propagates cranially in a segmental pattern.
• %HIF correlated significantly with both fissure depth and length:
  • %DHIF increased linearly (r = 0.989, p < 0.001)
  • %LHIF followed a sigmoidal relationship with %HIF (p < 0.001)
• Higher %HIF was significantly associated with:
  • Clinical lameness (p = 0.004)
  • Distal shift in the fissure center (CHIF)
• Implant complications in 5/17 elbows treated with transcondylar screws
• Isthmus diameter increased with weight (p = 0.002), relevant for screw sizing

🔍 Key Findings

• Left fourth intercostal thoracotomy allowed successful thoracic duct (TD) ligation in 9/10 canine cadavers.
• 10/13 clinical cases had a single TD branch at the left fourth intercostal space, indicating lower anatomical complexity.
• All TD branches at this site were lateral to the esophagus, simplifying surgical access.
• Unilateral subphrenic pericardiectomy was successfully performed via the same incision in 10/10 cadavers.
• Fewer TD branches at the fourth intercostal space than traditional caudal sites may reduce the risk of missed collaterals.
• In contrast, traditional caudal TD ligation sites had up to 5 branches, requiring broader dissection.
• No cadaver had right-sided TD branches, reducing surgical complexity at the studied location.
• Contrast-confirmed ligation was effective in 90% (9/10) cadavers on CT imaging.

🔍 Key Findings

• Overall survival to discharge: 107 of 132 dogs (81%)
• Quartile improvement: Survival increased steadily from 67% in Q1 to 91% in Q4
  • Q1: 22/33 survived
  • Q2: 27/33
  • Q3: 28/33
  • Q4: 30/33
• Statistical significance: Higher operative rank significantly associated with improved survival (p < .05)
• Median cross clamp time (XCT): 73 min (range 40–165), but increased again in Q4
• Fatalities (n=25) were often due to:
  • Failure to wean from CPB
  • Intracranial vascular events (stroke)
  • Intrathoracic hemorrhage
• Breed representation: CKCS (23.5%), Chihuahua (22%), Crossbreeds (21%)
• Stages of MMVD: Stage C (67%), Stage D (27%), Stage B2 (6%)
• Emphasis on deliberate multidisciplinary teamwork for outcome improvement
• Highlights importance of technical and non-technical team skills, procedural standardization, and consistent personnel

🔍 Key Findings

• Flushing the common bile duct (CBD) during cholecystectomy did not result in improved hepatobiliary markers compared to no flushing.
• Cholecystectomy alone significantly reduced ALP, ALT, GGT, bilirubin, and cholesterol 3 days postoperatively (p < .05 for all).
• Survival to discharge was 90.3%, with no survival difference between flushed and non-flushed groups.
• Postoperative pancreatitis occurred in 12.9% of dogs, evenly distributed between groups, suggesting flushing did not increase risk.
• Most common complication was regurgitation (29%), not significantly different between groups.
• Free abdominal fluid had low sensitivity (29%) but moderate specificity (73%) for gallbladder rupture.
• No difference in duration of hospitalization or postoperative complications between groups.
• Gallbladder rupture rate was 12.9%, lower than previously reported in literature.

🔍 Key Findings

• No significant difference in peak load, failure load, stiffness, or 3 mm gap formation among bone tunnel types.
• Transverse tunnel (TT) constructs had 25% higher yield load than modified tunnels (MT) (P = .027).
• Most common failure mode was suture pull-through (67%), with no significant difference between groups.
• Gap formation ≥3 mm occurred in ~90% of constructs; no significant difference in force needed for gap among groups.
• All bone tunnel techniques (TT, VT, MT) are viable options for CCT reattachment in dogs.
• The 3-loop pulley (3LP) pattern provided strong, uniform repair, with higher loads to failure than previously reported.
• TT constructs showed more tendon distortion at the repair interface during loading.
• Inclusion of accessory tendon may have improved repair strength compared to prior studies using GT alone.

🔍 Key Findings

• Study Design: Cadaveric model using four large-breed dogs with 10x10 cm full-thickness wounds at four locations (shoulder, thorax, flank, thigh).
• Configurations Tested: Diagonal, opposite, parallel, and perpendicular placements of wound infusion catheter and JP drain.
• Fluid Retrieval:
  • No significant difference by configuration (p = .92) or location (p = .32).
  • Perpendicular configuration had the highest mean retrieval (11.35 mL, 56.8% of instilled volume).
  • Flank location had the lowest retrieval (7.2 mL, 35.9%).
• Surface Area Coverage:
  • Parallel configuration achieved the highest SA coverage (83.4% ± 11.6%, p < .01).
  • Perpendicular was lowest.
• Leakage:
  • No difference in leakage between configurations (p = .74) or locations (p = .10).
  • Leakage commonly occurred at drain or catheter entry points (93.8% of wounds).
• Conclusion: Parallel drain configuration optimized fluid dispersion. Infusion-retrieval systems may allow for topical therapy delivery in closed wounds.
