🔍 Key Findings

PL-30 group (partial, TA30-V3 wedge):

• 100% leaked
• Median leakage pressure: 10 cm H₂O
• Most failures from periphery of staple line

PL-60 group (partial, TA60-3.5):

• 100% leaked
• Median leakage pressure: 18 cm H₂O
• Better than PL-30 (p = .006)

TL-30 group (total, TA30-V3):

• Only 1 of 11 leaked (at 22 cm H₂O)
• All others resisted pressures >50–65 cm H₂O
• Significantly higher leakage pressure than both PL groups (p < .001)

Odds ratios (leakage vs TL-30):

• PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
• PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)

Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.

🔍 Key Findings

• 73 elbows (52 dogs) underwent randomized medial or lateral transcondylar screw placement for HIF.
• Lateral-to-medial placement resulted in a significantly higher rate of complications (62.2%) vs medial-to-lateral (19.4%) (p = .001).
• Odds ratio for complications: 6.11 (95% CI: 2.13–17.52).
• Most common complications: seromas (n = 13), surgical site infections (n = 16).
• Implants with lower AMI/bodyweight were significantly associated with major complications (p = .037).
• Only 4 procedures (5%) required revision surgery (major type I complications), with no difference by screw direction.
• NNT = 2.3 for medial placement to prevent one complication.

🔍 Key Findings

• 14 joints from 7 cat cadavers underwent AA-HTS successfully.
• Median surgical time: 46.5 min (29–144), including 7 min for arthroscopy and 40 min for toggle placement.
• Intraoperative complications in 5/14 joints: 4 related to femoral tunnel creation, 1 toggle lodging.
• Toggle passage through femoral tunnel was the most challenging step, mildly difficult in 6 joints.
• Cartilage injury occurred in 10 joints, but all were minor (<10% of cartilage area).
• 13 deviations from planned technique were identified (8 major, 5 minor), all involving femoral tunnel placement.
• No neurovascular, intrapelvic, or major periarticular injuries occurred.
• Authors conclude: AA-HTS is feasible in cats, but associated with high rates of minor iatrogenic cartilage damage, intra-op complications, and technique deviations.

🔍 Key Findings

• Roux-en-Y procedures were successfully completed in all 11 cases (6 dogs, 5 cats), despite case complexity and disease severity.
• Median survival post-discharge was longer in cats (365 days) vs. dogs (82 days), with better outcomes in non-neoplastic vs. neoplastic disease (192 vs. 5 days).
• Complication rate was high, with septic peritonitis, dehiscence, and cardiac arrest as leading causes of postoperative death; mortality rate = 36%.
• Dehiscence rate was 8.6% (2 of 23 anastomoses), considered lower than typical rates for GI anastomoses in high-risk patients.
• Feeding tubes (gastrostomy/jejunostomy) were used in all cases, enabling early nutritional support and stomach decompression.
• Postoperative nausea and vomiting were common but mostly self-limiting; managed with metoclopramide, cisapride, and antiemetics.
• Choledochojejunostomy was preferred when common bile duct was dilated, offering a favorable size match and potentially reducing bile leakage.
• Roux-en-Y reduced typical Billroth II complications (e.g., bile reflux, afferent loop syndrome, dumping syndrome), with none observed in discharged patients.

🔍 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.

🔍 Key Findings

• This study evaluated whether high-fidelity surgical simulator training improved live animal and student outcomes in a feline OHE teaching lab involving 186 cats and 146 students.
• Simulator training significantly improved surgical performance and outcomes:
  • Live surgery was 6 minutes shorter on average in the SIM group vs. NO-SIM (115 ± 21 min vs. 121 ± 16 min, p = .04).
  • Pain scores ≥5/20 occurred in 1% of SIM group cats vs. 15% of NO-SIM group cats (p < .01).
  • Rescue analgesia was needed less frequently in the SIM group (5% vs. 15%, p = .03).
  • Student confidence was significantly higher in the SIM group (median 7/10 vs. 6/10, p < .01).
• The simulator used a realistic abdominal model with friable tissues and required performance of a full OHE procedure.
• The study design was nonrandomized, grouped by class year, with limitations including lack of blinding during pain assessment in year two.
• Authors concluded that pre-lab simulator competency improves both animal welfare and student confidence, recommending it as a prerequisite for live surgical training.

🔍 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.

🔍 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

• CT correctly identified ectopic ureters in 91% of dogs, but missed 50% of normal ureters, limiting its negative predictive value.
• Sensitivity for intramural ectopic ureters was 65%, while specificity was 71%, indicating moderate diagnostic performance.
• Sensitivity for extramural ectopic ureters was only 29%, despite a high specificity of 97%.
• CT was inaccurate in predicting ureteral orifice location, with sensitivity ranging from 0% to 76% depending on the site.
• 26% of dogs were misclassified for cystoscopic laser ablation (CLA) eligibility based on CT findings alone.
• Overall CT accuracy for CLA candidacy was 74%, but a significant minority would have been inappropriately treated.
• Multivariate analysis found no predictive factors (e.g., colon distension, body weight) for when CT would be incorrect.
• Authors recommend confirmatory cystoscopy to verify CT findings prior to treatment planning.

🔍 Key Findings

• MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
• Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
• MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
• Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
• MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
• Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
• Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
• The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.
