In Alvarez-Sanchez 2023 et al., on SLN mapping in canine MCT, which tumor type showed unexpectedly high rates of lymph node metastasis?
🔍 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 Sandoval 2024 et al., on lung lobectomy technique outcomes, how many lobectomies per group are needed for a superiority study comparing SLL and stapler?
🔍 Key Findings
- Intra- and postoperative complications occurred only in stapled lobectomies, but the difference was not statistically significant (intra: p = .069, post: p = .112).
- Intraoperative hemorrhage was the most common complication (11.8%), followed by air leakage (2%).
- All self-ligating loop (SLL) lobectomies had zero complications (n=18), though the sample was small.
- Postoperative complications included 4 catastrophic events (cardiopulmonary arrest), all in stapled cases.
- Lung lobectomy technique was not associated with duration of chest tube use, hospitalization, or survival (p > .05).
- 94.3% of patients survived to discharge (82/87).
- SLLs are lower-cost and may be more feasible for thoracoscopic/minimally invasive approaches due to smaller port size (5mm vs. 12mm for staplers).
- A future superiority study would need ≥103 lobectomies per group to assess differences in complication rates.

In You 2025 et al., on barbed sutures for lung lobectomy, what was the main advantage of barbed sutures compared to traditional sutures?
🔍 Key Findings
- Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
- No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
- Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
- Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
- Staplers remained fastest, with mean ligation time of 2.4 minutes.
- No knot failure or suture breakage was observed in barbed or traditional suture groups.
- Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
- Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

In Downey 2023 et al., on thoracoscopic lobectomy, what was the rate of survival to discharge?
🔍 Key Findings
- Thoracoscopic (TL) or thoracoscopic-assisted (TAL) lobectomy was successfully performed in 12 dogs with non-neoplastic pulmonary consolidation (PC).
- 44% (4/9) of TL cases were converted to open thoracotomy due to adhesions or poor visualization—higher than rates for neoplastic lobectomies.
- OLV was successful in 7/9 TL dogs; unsuccessful attempts were managed with intermittent ventilation, mostly in brachycephalic breeds.
- Median hospital stay was 3 days; 91.7% (11/12) survived to discharge, and 100% of survivors showed no recurrence at median 24-month follow-up.
- Complications were mostly minor: pneumothorax (2), minor hemorrhage (3), dehiscence (1), and 1 fatality due to BOAS complications.
- Histopathology showed infectious pneumonia in 10 dogs, and in 4 cases, foreign body migration was suspected as the underlying cause.
- Median surgical time for TL was 90 minutes; conversion correlated with longer symptom duration (median 90 vs. 7 days).
- Postoperative recovery was excellent in all surviving dogs, with one case of persistent cough attributed to concurrent heart disease.

In Lomas 2025 et al., on DPO and dorsolateral subluxation, what percentage of hips had a post-DPO DLS score <55%, indicating higher OA risk?
🔍 Key Findings
- DPO significantly improved femoral head coverage, increasing mean DLS from 36.1% to 71.4% postoperatively (p < 0.001).
- No significant change in DLS between immediate postoperative and follow-up scans, suggesting stable surgical outcomes over time.
- Greater plate angle (30°) yielded larger DLS improvement (mean increase: 39.8%) compared to 25° and 20° plates.
- Only 3 hips had post-op DLS scores <55%, indicating most patients had lower risk of osteoarthritis progression.
- No correlation found between DLS improvement and age, body weight, or side of surgery, suggesting broad applicability.
- CT was used for DLS measurement in simulated weight-bearing, improving precision over radiographic methods.
- Major limitations included small sample size, multiple surgeons, and variable sedation vs anesthesia during imaging.
- DPO confirmed as effective for reducing dorsolateral subluxation, improving coxofemoral joint congruency in dysplastic dogs.

In Tobias 2022 et al., on perineal hernia repair positioning, which surgical advantage did dorsal recumbency provide?
🔍 Key Findings
- Perineal hernia repair was feasible in dorsal recumbency in all 23 dogs, allowing simultaneous perineal and abdominal procedures without repositioning.
- Internal obturator muscle transposition (IOMT) was successfully performed in 22 dogs, with tendon transection facilitating improved muscle elevation.
- Complication rate was 60.9% in-hospital and 47.8% post-discharge, mostly minor (e.g., swelling, drainage), with infection suspected in 4 dogs (17.4%).
- Recurrence rate was 19% overall, but significantly higher in dogs with prior hernia repairs (50% vs 5.9%; p = 0.053).
- Dogs without prior repairs or organ pexies had no recurrences (p = 0.035), suggesting primary repairs without preexisting interventions fare better.
- Castration and adjunctive abdominal procedures (e.g., colopexy, cystopexy) were often performed concurrently (18/23 dogs).
- Colopexy did not prevent recurrence, although it aided in surgical visualization during perineal repair.
- Dorsal positioning allowed simultaneous access to the abdomen and perineum, improving surgical efficiency without added complications.

In Cortina 2023 et al., on modified TTT outcomes for MPL in dogs, what was the function of the tension band construct?
🔍 Key Findings
- m-TTT yielded a low overall major complication rate (4.3%) and minor complication rate of 15%, consistent with or better than previous techniques.
- Patellar reluxation occurred in only 4.3% of stifles, with high-grade reluxation seen in just 0.6% of cases—lower than the 12.4–21% range reported for other techniques.
- Implant migration rate was 3.7%, lower than previously reported for smooth pin fixation (7.7–24.6%).
- Use of a tension band with single Steinmann and Kirschner wire reduced stress risers and fixation failure, supporting better stability.
- Tibial tuberosity fracture occurred in only 1.3% of cases, lower than the 1–6% seen in other reports.
- All long-term major complications (1.3%) were related to pin migration, but were easily resolved.

In Danielski 2025 et al., on PUO complication reduction, what was the study's implication for **chondrodystrophic breeds**?
🔍 Key Findings
- Combined intramedullary (IM) pin and rhBMP-2 use resulted in a low complication rate (7.4%) after proximal ulnar osteotomy (PUO).
- Major complications occurred in 5.3% of cases (4 infections, 1 pin breakage with ulnar tilt requiring revision).
- Minor complications occurred in 2.1% of cases (seroma, delayed union).
- No cases of non-union were observed; 98.9% of limbs achieved radiographic healing by 6 weeks.
- IM pin breakage was noted in 11.8% of limbs but did not affect healing outcomes.
- Chondrodystrophic breeds made up 64.8% of the cohort and tolerated the procedure well.
- Compared to prior studies, complication rates were substantially reduced with this technique (prior major: 13.9%; this study: 5.3%).
- The use of rhBMP-2 likely enhanced early bone healing and provided biologic support, particularly important in breeds at higher risk of complications.
