🔍 Key Findings

• Liver lobectomy was the most common treatment (27/36 dogs), with multiple lobes removed in ~1/3 of cases.
• Septic peritonitis was present in 21/23 sampled dogs, making it a frequent complication.
• Perioperative complications occurred in 21/36 dogs, including aspiration pneumonia, pancreatitis, and acute kidney injury.
• Intraoperative hypotension was common (32/36), often requiring vasopressors or colloids.
• Mortality prior to discharge was 21% (8/38), with deaths related to sepsis, aspiration pneumonia, and multi-organ dysfunction.
• Median survival time was 638 days in dogs surviving to discharge.
• No recurrence of hepatic abscessation was observed in the surviving population.
• E. coli and Clostridium spp. were the most commonly cultured organisms, often as single-agent infections.

🔍 Key Findings

• Endoscopic excisional biopsy of axillary lymph nodes was successfully performed in cadavers and clinical dogs with minimal complications.
• The technique used a SILS port and CO₂ insufflation through a small incision between the latissimus dorsi and superficial pectorals.
• In 4 cadavers (6 limbs), mean time to remove axillary nodes was 33 minutes, and single nodes were found in 5/6 limbs.
• In 3 clinical dogs, the procedure was successful in 2 cases; 1 required conversion to open surgery due to difficulty manipulating the node.
• Accessory axillary nodes were successfully excised when present, located adherent to deep latissimus dorsi.
• No cases developed lymphedema, pneumothorax, or major complications postoperatively.
• Subjective benefits included better visualization, reduced dissection, and less postoperative morbidity than open techniques.
• Study suggests MIS lymphadenectomy may improve staging accuracy and reduce complications, though larger studies are needed.

🔍 Key Findings

Population: 9 dogs underwent revision of osteointegrated acetabular cups after total hip arthroplasty (THA)

Revision Indications:

• 7 luxations (5 ventral, 2 craniodorsal)
• 1 femoral stem fracture
• 1 aseptic stem loosening

Implants:

• 8 BFX cups, 1 Helica; all revised to BFX
• 7/9 required a larger cup than original

Cup removal: Required sectioning with a high-speed burr and modular osteotome; removal fragments extracted

Complications:

• 1 recurrent luxation
• 1 low-grade infection with possible metallic debris-associated osteolysis
• 2 femoral fissures managed intraoperatively

Outcomes:

• Good to excellent function in 6/6 dogs available at median 621 days
• Minimal complications with success in re-osteointegration of new cup

Clinical takeaway: Revision of stable, ingrown cups is feasible and offers an alternative to pelvic osteotomies; typically requires upsizing

🔍 Key Findings

Overall accuracy of radiography to detect IAIP: 77.9%

Sensitivity: 97.2%
Specificity: 67.6%

False positive rate: 32.4% of non-penetrating implants were misclassified as penetrating

Implants directed toward the lateral tibial condyle had higher misclassification (23.8%) than medial (8.3%)

Most accurate detection: Implants placed 2 mm into the joint (97.2% correct classification)

Least agreement: For implants placed at 0 mm (subchondral level), especially lateral (AC1 = 0.48)

No palpable abnormalities (e.g., crepitus) observed during ROM for any group

No significant difference in detection by specialty field or reviewer qualification

Suggests radiographic misclassification risk and supports considering CT/fluoroscopy in equivocal cases

🔍 Key Findings

• Peripheral nerve block (PNB) was preferred by 79% of anesthesiologists; lumbosacral epidural (LE) by 21%; PI <1%.
• Time since board-certification significantly influenced preference: PNB favored by newer diplomates, LE favored by more senior ones (p < .001).
• Employment sector mattered: PNB was preferred more in private practice, LE more in academia (p = .003).
• PNB perceived as more effective, with 78% reporting 81–100% effectiveness; compared to 55% for LE.
• PNB associated with fewer adverse effects (75%) than LE (4%) and PI (21%).
• PNB required less rescue analgesia intraoperatively (57%) and postoperatively (54%) than LE or PI.
• LE preferred for bilateral TPLOs and in smaller dogs; PNB for larger dogs, due to motor function preservation.
• Dexmedetomidine was the most common additive to PNB; bupivacaine-only was most used for PNB.

🔍 Key Findings

• Local recurrence occurred in 17.8% of dogs, and was associated with significantly decreased survival (551 vs 1722 days, p = .0038).
• Lymph node metastasis occurred in 26.7% of dogs and was significantly associated with shorter disease-free interval (194 vs not reached, p = .0012) and lower survival (551 vs 1722 days, p = .043).
• Mitotic index >7 was significantly associated with higher recurrence (80% vs 22.5%, p = .02), shorter DFI (139 vs not reached days, p < .001), and shorter survival (247 vs 1722 days, p = .05).
• Infiltrative growth pattern was associated with shorter DFI (268 vs 1864 days, p = .011), but not with survival or recurrence.
• Incomplete margins (≤1 mm) were not significantly associated with recurrence (p = .085), but did correlate with shorter DFI (p = .043).
• Chemotherapy or radiation therapy was associated with shorter DFI and survival, likely due to selection bias for more aggressive disease.
• Tumor size >3 cm was associated with decreased survival (p = .031), but not with recurrence or DFI.
• Multinucleation and necrosis were not associated with prognosis outcomes.

🔍 Key Findings

• Adding a single locking throw significantly increased holding security for specific knots, including the surgeon's throw (p = .0001) and square throw (p = .0002).
• For the Miller's throw (p = .166) and strangle throw (p = .808), no significant improvement was observed with a locking throw.
• After locking throw addition, all five knots leaked at similar pressures (p = .5233), and these pressures exceeded physiologic arterial pressures.
• Surgeon's throw without a locking throw had the lowest leak pressure (62.5 ± 46.2 mm Hg), below physiologic arterial values.
• The square throw without locking also leaked below physiologic pressures (148.7 ± 109.4 mm Hg), though it outperformed the surgeon's throw.
• Miller’s and strangle throws performed significantly better than square or surgeon’s throws without locking, achieving leak pressures >200 mm Hg.
• All knots used 2-0 polyglyconate monofilament (Maxon); no comparisons across suture types or sizes were performed.
• Authors concluded that correct tensioning and locking throw addition are key to safe vascular ligation. Miller’s, strangle, or slip knots are preferred for challenging surgical fields.

🔍 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

• Esophageal pH-monitoring was well tolerated in all 35 nonbrachycephalic dogs, with no major adverse events reported.
• Distal GER occurred in 80% of dogs, but events were typically brief and non-productive; proximal GER occurred in only 39%.
• Upper reference limits for GER were 2.4 events/hour (distal) and 0.4 events/hour (proximal).
• Cumulative acid exposure was minimal: upper limits were 2.3% (distal) and 0% (proximal).
• Comparison with brachycephalic dogs shows significantly higher GER frequency and duration, validating the diagnostic utility of pH monitoring.
• Transnasal probe placement under light anesthesia was safe and less morbid compared to percutaneous or conscious techniques.
• No expelled or productive regurgitation occurred, despite some GER events, indicating efficient esophageal clearance in healthy dogs.
• Diet and fasting duration may affect GER, but these were not controlled variables in this study.

🔍 Key Findings

• Double forwarder (DF) knots had significantly higher knot holding capacity (KHC) than square (SQ) and surgeon’s (SU) knots when tied with <6 throws.
• In 3 USP polyglactin 910, DF knots with 4–5 throws were not significantly stronger than SU knots with 6–8 throws (p > .43).
• DF knots never unraveled, while SQ and SU knots with 4–5 throws showed substantial unraveling.
• KHC did not increase in DF knots when throws increased from 3 to 5.
• Knot volume and weight were significantly higher in DF knots than SQ/SU knots at the same throw count (p < .003).
• DF knots allow sliding placement, potentially useful in minimally invasive or deep cavity procedures.
