In Cantatore 2022 et al., on transanal submucosal resection, what proportion of dogs with recurrence were successfully treated with a repeat submucosal resection?
🔍 Key Findings
- Submucosal resection via a transanal approach was associated with a low rate (1.1%) of major complications and prolonged survival across benign and malignant rectal tumors.
- Overall recurrence rate was 21.5%, with higher recurrence in malignant tumors: 28.6% (carcinomas) and 30.4% (carcinoma in situ) vs. 13.6% (adenomas).
- Complications (P = .032) and incomplete margins (P = .023) were independently associated with increased recurrence risk.
- Recurrence was the only factor associated with increased risk of tumor-related death (P = .046).
- Repeat submucosal resection was successful in 60% of dogs with recurrence, indicating feasibility of this as a salvage approach.
- 1-, 2-, and 5-year survival rates for carcinomas were 95%, 89%, and 73%, though overall survival was significantly longer for benign tumors (P = .001).
- Preoperative diagnostics (FNA, biopsy) were often inconsistent with final histopathology – only 64.3% biopsy agreement.
- Presurgical imaging was not consistently performed, limiting accurate staging in many dogs.

In Morgera 2022 et al., on stifle surgery draping methods, which draping technique was found to significantly reduce infection-inflammation?
🔍 Key Findings
- No significant difference in infection-inflammation rates between single-layer Kraton drapes and traditional double-layer draping at both 21 days and 6 months postop.
- Infection-inflammation occurred in 4.56% (36/789) of cases; equally distributed across draping techniques.
- Tibial tuberosity advancement (TTA) was the most common procedure (61%).
- Kraton drape features an elastic fenestration that seals without adhesives or towel clamps, offering ecological and workflow advantages.
- Mean anesthesia duration was similar between groups (~73.8 min), suggesting draping method did not impact overall surgical time.
- Culture confirmation of infection was low (14 dogs), showing reliance on clinical criteria for diagnosis.
- Potential benefits of single-layer draping include reduced waste, no need for towel clamps, and ease of use without increased risk.
- Limitations included subjective follow-up (nearly 30% indirect via phone/images) and antimicrobial usage in all cases.

In McCarthy 2022 et al., on 3D drill guide accuracy, what was the primary proposed benefit of using a 3D-printed guide?
🔍 Key Findings
- 3D-printed drill guides (3D-GDT) significantly reduced craniocaudal and dorsoventral drilling angle deviation compared to free-hand drilling technique (FHDT), with statistical significance (p < .0001 and p = .01 respectively).
- No sacral corridor breaches occurred with 3D-GDT, whereas FHDT resulted in 20% drill exit incidences (3/15 cases).
- 3D-GDT had lower deviation from optimal drill trajectory at end points in all axes: craniocaudal (1.84 ± 1.6 mm vs. 4.18 ± 2.4 mm), dorsoventral (1.11 ± 1.0 mm vs. 2.4 ± 1.5 mm), and 3D linear (2.47 ± 1.4 mm vs. 5.35 ± 2.2 mm), all statistically significant.
- Strong correlation (r = 0.77) between CT and 3D software measurements validated method reliability.
- 3D guide trajectories showed consistent proximity to the optimal trajectory, especially at drill endpoints, indicating reduced variability in execution.
- 3D-GDT was developed using open-source software and inexpensive materials, supporting future clinical application.
- Major errors in FHDT occurred primarily at the drill endpoint, underscoring the challenge of maintaining optimal angulation during free-hand drilling.
- The sacral corridor was recharacterized as pyramidal (not quadrilateral), with implications for safer implant placement.

In Trefny 2025 et al., on locking plate biomechanics, when did transcortical contact occur in long working length constructs?
🔍 Key Findings
- Short working length constructs had significantly higher stiffness and lower strain than long constructs in compression bending (p = 0.0172).
- In tension bending, short constructs also had higher precontact stiffness and lower strain, but this reversed after transcortical contact (~150 N).
- Transcortical contact increased stiffness only in long constructs, producing a bilinear load-displacement curve.
- Postcontact stiffness was higher in long constructs, but this may not reflect clinical benefit due to risks of high interfragmentary strain.
- Short working length reduced strain at multiple ROIs under both loading conditions, including over fracture gap (Tables 1–3).
- Increased working length promoted stress concentration and deformation, especially in compression bending.
- In vitro benefits of long constructs (via contact stability) may not translate to healing, as repetitive loading could increase plate strain and bone resorption.
- Plate strain was effectively mapped using 3D digital image correlation, confirming regional strain differences between configurations.

In David 2024 et al., on single-port cryptorchidectomy, what was the most common method used for transection of the spermatic cord?
🔍 Key Findings
- Single-port laparoscopic-assisted cryptorchidectomy (SP-LAC) was feasible in 13/14 dogs with abdominal cryptorchidism.
- Median surgical time was 17 min for unilateral and 27 min for bilateral cryptorchidectomy.
- All testes were successfully exteriorized through a 15-mm mini-celiotomy in most dogs; only 2 needed slight enlargement.
- One major complication occurred (testicular artery hemorrhage, requiring conversion to open surgery).
- Two minor complications involved trocar-related issues (splenic capsule laceration, capnoretroperitoneum).
- No incisional complications were reported postoperatively; some dogs had mild dermatitis at the clipped site.
- The technique requires only one surgeon and no advanced tools beyond a single-port endoscope.
- Low-pressure capnoperitoneum (6 mmHg) was adequate for visualization in most cases.

In Song 2024 et al., on CT vs cystoscopy for ectopic ureters in dogs, what percentage of dogs with normal ureters were missed by CT?
🔍 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.

In Gutbrod 2024 et al., on feline tibial stabilization, why might plate–rod constructs be preferred for feline tibial fractures?
🔍 Key Findings
- 2.4 mm LCP with a 1.6 mm IM pin had the highest axial stiffness and yield strength among the tested constructs.
- Axial stiffness was significantly higher in the 2.4 mm LCP + 1.6 mm IM pin group compared to 2.7 mm LCP alone (p = .013).
- No significant difference in torsional stiffness was found among groups.
- 2.4 mm LCP + 1.0 mm pin had the lowest stiffness and failure load, underperforming both other constructs.
- All constructs failed via valgus bending, consistent with clinical observations in feline tibial fractures.
- A 1.6 mm pin (~50% canal fill) resulted in superior construct performance vs. 1.0 mm (~30% fill).
- Group 2 (2.4 LCP + 1.6 mm pin) outperformed the 2.7 mm LCP alone in stiffness, despite using a smaller plate.
- Plate–rod constructs may better preserve periosteal blood supply and support minimally invasive stabilization strategies.
