In Buote 2023 et al., on laparoscopic sleeve gastrectomy in cats, which complication occurred in 2 cadavers due to stapling too close to the lesser curvature?
🔍 Key Findings
- LVSG was feasible in 9/10 feline cadavers and both live cats, with no intra- or postoperative complications in live cases.
- Two cadavers developed suspected stenosis due to staple lines too close to the lesser curvature; avoided with orogastric tube placement in later cases.
- No evidence of gastric leakage in any cadavers (8/10 tested) or live patients after methylene blue leak tests.
- Mean surgical time was ~110 min cadavers / 115 min live, and 27.6% of stomach mass was resected.
- Both live cats recovered uneventfully, lost 21–24% body weight over 3 months, and had no GI complications at 6-month follow-up.
- Orogastric tube and tension on the greater curvature were critical to avoid staple line misplacement or stenosis.
- No oversew of the staple line was needed, and unreinforced staples showed no leakage in live patients.
- Future studies needed to assess metabolic outcomes and ideal staple sizing and closure techniques.

In Alvarez-Sanchez 2023 et al., on SLN mapping in canine MCT, what was the histologic metastasis rate (HN2 or HN3) in excised lymph nodes?
🔍 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.

In Bush 2023 et al., on canine salivary gland carcinoma, what was the concordance rate between incisional biopsy and final excisional histopathology?
🔍 Key Findings
Source: Bush et al., 2023, Veterinary Surgery
- Median survival time (MST) after surgery was 1886 days, which is significantly longer than previously reported.
- Lymph node metastasis at surgery was a negative prognostic factor, reducing MST to 248 days (vs. 2340 days without nodal involvement).
- Local recurrence occurred in 42% of dogs, with a median disease-free interval (DFI) of 191 days.
- Metastatic disease occurred in 32% of dogs, most commonly to the lungs, with a median DFI of 299 days.
- Histologic features (e.g., margin status, capsular, lymphatic, or vascular invasion) were not significantly correlated with recurrence or metastasis.
- Facial nerve injury occurred in 9.7% perioperatively, especially after parotidectomy; intraoperative facial nerve transection led to long-term deficits.
- Adjuvant therapies (chemotherapy, radiation, NSAIDs) did not significantly affect survival time.
- Incisional biopsy was only 38% concordant with final excisional histology, suggesting limited reliability for definitive diagnosis.

In Petchell 2025 et al., on CORA-based CCWO, what is the primary purpose of plotting both PMA and DMA lines in the CCWOCORA technique?
🔍 Key Findings
- The CORA-based cranial closing wedge ostectomy (CCWOCORA) consistently achieved the target postoperative TPA of 5° across all tibial morphologies.
- CCWOCORA produced significantly less variability in postoperative TPA compared to other methods (TPA range: 5.00–5.00°; p < .001).
- Mechanical axis advancement (MAA) was precisely controlled at 3° in CCWOCORA, leading to greater surgical predictability.
- Other techniques (e.g., CCWOTPA, CCWOTPA–5, CCWOISO) showed greater variance in TPA, MAA, and tibial length.
- In small-breed dogs, increasing the MAA from 3° to 5° did not affect TPA outcomes, but increased proximal bone stock, improving feasibility.
- Wedge angles and tibial length changes varied by method, but CCWOCORA maintained length better than TPA-based methods.
- The technique allows preoperative planning of both desired MAA and TPA, enhancing predictability and customization.
- CORA methodology enables precise geometric correction and alignment of mechanical axes, reducing reliance on trial-and-error alignment.

In Nagahiro 2023 et al., on quadriceps-femoral mismatch, how did the PLL/PL ratio (indicator of patella alta) relate to QML/FL or MPL severity?
🔍 Key Findings
- Quadriceps muscle length/femoral length ratio (QML/FL) was significantly lower in dogs with grade IV MPL than grades I–III (p ≤ .002).
- Shortened QML was associated with increased femoral torsion angle (FTA) and increased aLDFA, indicating correlation with femoral deformity.
- QML/FL increased with age, possibly due to muscular development or reduced deformity in older dogs (p = .004).
- Grade IV MPL dogs had QML/FL < 0.87, the lower normal limit based on healthy beagles, suggesting clinically significant muscle shortening.
- PLL/PL ratio (used to diagnose patella alta) was not associated with QML/FL or MPL severity in small breeds.
- QML/FL can help preoperatively identify candidates for femoral shortening ostectomy, improving femoropatellar alignment.
- Multivariate regression model confirmed QML/FL is independently influenced by age, FTA, and aLDFA (R² = 0.45).
- CT-based 3D measurements enabled objective, noninvasive quantification of femoral and muscle alignment parameters.

In Thibault 2023 et al., on DPO for THR luxation, what was the reported impact of DPO on angle of lateral opening (ALO) and version angle (VA)?
🔍 Key Findings
- Double pelvic osteotomy (DPO) reduced angle of lateral opening (ALO) by a median of 11° (p ≤ .001).
- Despite ALO correction, THR reluxation occurred in 5/11 dogs, often within 7 days post-DPO.
- Post-DPO ALO remained elevated (median 56°), with only 2 dogs achieving the recommended 35–45° range.
- Explantation was required in 7/11 dogs (5 aseptic loosenings, 2 infections), suggesting poor long-term implant survival.
- Dogs with luxoid hips were more likely to fail, even with corrected ALO, emphasizing soft tissue instability as a risk factor.
- Compared to TPO (23° correction), DPO yielded a smaller ALO correction, possibly due to older dog population and less elastic pelvis.
- No ventral luxation occurred post-DPO, unlike in TPO studies, likely due to more conservative ALO reduction.
- Authors do not recommend routine DPO for THR luxation due to high complication and failure rates.

In Otero Balda 2025 et al., on Short-term outcomes after feline cPSS surgery, which of the following was **not** significantly associated with 30-day survival in PANS-affected cats?
🔍 Key Findings
- 78% of cats that developed postattenuation neurologic signs (PANS) after congenital portosystemic shunt (cPSS) surgery survived to 30 days.
- Postattenuation seizures (PAS) were associated with significantly decreased 30-day survival (50% vs. 78%; OR: 0.015, p = .005).
- Treatment of PANS with propofol was a negative prognostic factor (OR: 0.112, p = .0008).
- Generalized PAS accounted for most seizure cases and were more frequently fatal than focal or unknown-type seizures.
- Pretreatment with levetiracetam (LEV1 protocol) showed a trend toward improved survival (100% vs. 60.6% in untreated cats), though not statistically significant (p = .06).
- Shunt morphology, method of attenuation, and study period (early vs. late) were not significantly associated with 30-day survival.
- Electrolyte, glucose, and ammonia abnormalities were not strongly linked to survival outcomes in this study.
- Majority of PAS-related deaths were due to uncontrolled generalized seizures or euthanasia because of severity.

In Zann 2023 et al., on proximal humeral OC surgery, how did peak vertical force and vertical impulse compare between limbs?
🔍 Key Findings
- All dogs developed progressive osteoarthritis (OA) after surgical debridement of proximal humeral OC.
- Ipsilateral muscle atrophy and reduced shoulder range of motion were common, particularly in unilaterally affected dogs.
- Arthroscopically, lesions showed incomplete cartilage infilling even years after surgery, averaging only ~37% infilling.
- Synovitis was present in all joints, with moderate-to-severe hypertrophy and vascularity scores.
- CT identified OC lesions as deeper and wider than radiography, and all affected joints had more advanced OA than contralateral limbs (P = .001 radiograph, P = .005 CT).
- Kinetic gait analysis showed no significant differences in peak vertical force or impulse, but a subtle 4.4% asymmetric load reduction on the operated limb.
- Median LOAD score was 6, indicating mild owner-perceived disability despite measurable clinical and imaging abnormalities.
- Cartilage infilling was incomplete in all cases, with no lesion exceeding 60% restoration, raising questions about the healing potential of debridement alone.
