In Chik 2024 et al., on cholangioscopy feasibility, which factor most limited advancement of the 3.8 mm disposable endoscope into the common bile duct?
🔍 Key Findings
- Open transcholecystic cholangioscopy was feasible using a 3.8 mm disposable flexible endoscope in all 8 canine cadavers.
- Visualization was consistently achieved up to the junction of the hepatic ducts, common bile duct, and cystic duct.
- Advancement past the junction was limited by the endoscope diameter (3.8 mm) and anatomical flexure.
- The 1.9 mm flexible ureteroscope could visualize the entire biliary tree, including the major duodenal papilla, in a large dog (43.8 kg).
- Endoscopic tools (e.g., 3 Fr grasping forceps) could be passed through the working channel only after removing the irrigation line.
- Standard biopsy forceps were incompatible with the disposable endoscope's 1.2 mm working channel.
- Cadaver study showed no rupture, but clinical extrapolation is limited due to lack of diseased tissue.
- Disposable endoscope setup cost (~$6,100) was significantly lower than traditional endoscopy systems (~$75,000–100,000), improving accessibility.

In Morgera 2022 et al., on stifle surgery draping methods, what is a unique feature of the Kraton drape?
🔍 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 Matz 2022 et al., on stapler size comparison, what was the primary location of leakage observed in nearly all specimens?
🔍 Key Findings
- No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
- All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
- Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
- Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
- No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
- Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
- One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
- Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.

In Dickson 2024 et al., on VATS for feline chylothorax, what was the most common postoperative complication?
🔍 Key Findings
- Objective: To evaluate outcomes and complications of video-assisted thoracoscopic surgery (VATS) for idiopathic chylothorax in 15 cats.
- All 15 cats underwent thoracoscopic thoracic duct ligation (TDL); 13 also had simultaneous pericardectomy, 2 had VATS TDL + laparoscopic cisterna chyli ablation (CCA), and 1 cat had an open CCA.
- Median surgical time was 152.5 minutes (range 60–255).
- Contrast was used intraoperatively in 13 cats; 11 received methylene blue, and 2 received indocyanine green (ICG).
- One intraoperative complication (6%) occurred — a minor intercostal artery laceration. Conversion to open surgery occurred in 3 cases (20%) due to visualization issues or bleeding.
- Postoperative complications occurred in 8 cats (53%), with persistent pleural effusion in 5 cats (33%) being the most common.
- Mortality was high: 4 cats (27%) died or were euthanized before discharge. Only 7 of 11 cats discharged had resolution of effusion, and recurrence occurred in 1.
- Authors concluded that while VATS is technically feasible in cats, it did not improve clinical outcomes compared to open surgery, and feline idiopathic chylothorax continues to have a high mortality rate.

In Tobias 2022 et al., on perineal hernia repair positioning, what was the recurrence rate in dogs with prior hernia repair on the same side?
🔍 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 Ferreira 2025 et al., on tibial torsion measurement, what was the average torsion angle measured using the new method?
🔍 Key Findings
Objective: Validate a new 3D CT-based method for measuring tibial torsion in dogs with MPL, comparing it to a traditional method.
Sample: 40 tibiae from client-owned dogs with MPL (primarily small-breed).
Repeatability (intraobserver):
- New method: ICC = 0.99 → excellent agreement
Reproducibility (interobserver):
- New method: ICC = 0.83 → high agreement
- Traditional method: ICC = 0.52 → moderate agreement
Torsion angle measurements:
- New method avg: 16.00° ± 8.77
- Traditional method avg: 8.76° ± 4.92
Conclusion: The new method is more repeatable, reproducible, and provides higher torsion values than the traditional Aper method, especially reliable for small-breed dogs.

In Dobberstein 2024 et al., on liver biopsy forceps, how did the number of portal triads compare between forceps sizes?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Peycke 2022 et al., on CBLO in immature dogs, what was the most common **complication** from improper screw placement in CBLO?
🔍 Key Findings
- CBLO was effective for stifle stabilization in skeletally immature dogs with CrCL injuries, avoiding disruption of proximal tibial growth plates.
- Radiographic union of the osteotomy occurred in a mean of 6 weeks (range: 4–8 weeks), indicating rapid bone healing.
- Full limb function was restored in all cases by long-term follow-up (mean 23 months), including dogs with initial complications.
- Two dogs developed 19° valgus deformities due to screw interference with the proximal tibial physis; both were corrected surgically with return to function.
- One dog developed 10° recurvatum due to over-rotation of the tibial plateau, but retained full function without revision.
- CCS (countersink compression screw) caused early apophyseal closure in older dogs but had no adverse clinical effects.
- In contrast, K-wire or plate-only fixation preserved open apophysis, suggesting implant choice may influence growth.
- No meniscal injuries were observed, and all CrCL injuries were managed arthroscopically — 6 complete, 6 partial, 4 avulsions.
