🔍 Key Findings:

• Study design: Retrospective, 20 cats with congenital EHPSS treated with ameroid ring constrictor (ARC).
• Perioperative complication rate: 25% (5/20), including seizures, blindness, ascites, and one death.
• Short-term outcomes (18 cats):
  • Excellent: 14
  • Good: 2
  • Poor: 2
• Long-term outcomes (18 cats):
  • Excellent: 15
  • Good: 1
  • Poor: 2
• Persistent seizures: Noted in some cats despite normal bile acids and CBC/chemistry.
• Preoperative blindness resolved in most cats.
• Mean follow-up duration: Median 8 years.

🔍 Key Findings

• Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
• PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
• No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
• No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
• Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
• SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
• Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
• No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.

🔍 Key Findings Summary

• 47 dogs (57 elbows) underwent TCS placement for HIF
• Overall complication rate = 17.5%
  • Minor: seromas (7 elbows)
  • Major: septic arthritis (3 elbows) — all resolved with antibiotics
• No screw failures, medial epicondylar fractures, or catastrophic outcomes noted
• Long-term follow-up in 41 dogs (50 elbows):
  • 90% full function, 10% acceptable function
  • Mean follow-up = ~2.5 years
• Increased age was significantly protective (p = 0.0051; OR = 0.61)
• TCS placement method (freehand, guide, aiming device) significantly impacted screw angulation but not complication rate
• Outcome not affected by presence of complications

🔍 Key Findings

• Oxley's modified CCWO did not achieve the target TPA of 5° in most cases, even with planning.
• Mean planned TPA was 7.6°, higher than target, and consistent across dog sizes.
• Postoperative TPAs were significantly higher in small dogs (median 7°) than in large dogs (median 4.5°).
• Distalization >7.5 mm of the osteotomy from the patellar tendon led to increased under-correction of TPA.
• Only dogs with preoperative TPA >35° achieved post-planning TPAs close to the 5° target.
• Postoperative osteotomy positions were generally more distal than recommended (8.6 mm median).
• Virtual plate fit was appropriate for all dogs at 5 mm or 7.5 mm positions, suggesting no need for excessive distalization.
• Excessive correction leading to negative TPAs occurred in some cases, risking caudal cruciate ligament strain.

🔍 Key Findings

• Cats with linear (LFBO) and discrete (DFBO) small intestinal obstructions had similar survival (98.2% vs. 97%, p = 1.0).
• Postoperative complications were not significantly different between LFBO and DFBO cases (p = .1386).
• Intestinal dehiscence was rare (only 2 cats), both in DFBOs, with no statistical difference between groups.
• Red rubber catheter technique (RRCT) successfully removed LFBOs in 83% (20/24) of attempts.
• All failed RRCTs occurred in cats with perforations or tissue nonviability.
• Cats with failed RRCTs had longer clinical signs pre-surgery (median 6.5 vs. 2.0 days).
• Surgical time was longer in LFBO cats (median 77 min vs. 58 min, p = .0018).
• Preoperative septic peritonitis was rare (4/169 cats), but occurred only in linear or mixed FBO cases.

🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

🔍 Key Findings

• Mediastinoscopy was technically feasible in large-breed canine cadavers using a SILS port and standard laparoscopic instruments.
• The left tracheobronchial lymph node (LTBLN) was successfully retrieved in all cadavers (7/7), while cranial mediastinal lymph nodes were retrieved in only 1/7.
• Postprocedural pleural gas was observed in 4/7 cadavers, likely due to CO₂ insufflation.
• Instrument limitations with a human-designed mediastinoscope led to preference for laparoscopic instruments and SILS port for improved access and visualization.
• Complication rates were low, with only two minor (Grade 1) adverse events (pleural tear and LN rupture).
• Obesity and mediastinal fat were cited as potential challenges to visualization and node retrieval.
• NASA-TLX workload scores were lowest for tracheobronchial nodes, indicating these were the easiest to access.
• The authors concluded this approach may facilitate minimally invasive biopsy or resection of cranial mediastinal masses in live dogs, but clinical trials are needed to validate safety and efficacy.

🔍 Key Findings

• PCCLm resulted in significantly fewer postoperative lower urinary tract signs compared to OC (13.0% vs 60.9%, p <.001).
• Incomplete urolith removal was not significantly different between PCCLm and OC (11.4% vs 20%, p = .112).
• PCCLm had significantly shorter anesthesia times than OC when no concurrent procedures were performed (97.5 vs 120 min, p < .001).
• Surgical site infection/inflammation (SSII) rates were low and not significantly different between groups (4.5% PCCLm vs 1.8% OC).
• Dogs undergoing PCCLm were more frequently discharged same-day (84.7% vs 0% in OC), reflecting faster recovery.
• PCCLm had higher intraoperative complication rates (22.1% vs 3.4%), mostly due to incision extension or conversions.
• Time to additional surgery for urolith recurrence was longer in PCCLm dogs (24 vs 11.5 months, p = .004).
• Calcium oxalate uroliths were more prevalent in PCCLm cases, while OC had more struvite or mixed types.

🔍 Key Findings

• Combined ICTL and NIRF detected the same SLN in 80% of cases; each method alone missed sentinel lymph nodes in some dogs.
• ICLT failed in 5% of dogs, while NIRF failed in 20%; combined use resulted in only 5% failure in SLN detection.
• Metastatic lymph nodes were detected in 95% of dogs, despite most tumors being low or intermediate grade (95%).
• 27 of 41 nodes (65.8%) were histologically metastatic (HN2 or HN3), many of which would have been missed using ALN alone.
• ALN matched the SLN in only 45% of cases with ICTL and 30% with NIRF, supporting the need for SLN mapping.
• ICLT and NIRF were complementary, often identifying different SLN, with some only fluorescent or enhanced in one modality.
• Subcutaneous MCT had higher metastatic rates (7/8 dogs) than previously reported, challenging older assumptions about benign behavior.
• Removing both ALN and SLN (from both methods) improved detection of metastasis to 85–95%, reducing risk of understaging.

🔍 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.
