In Mullen 2023 et al., on microvascular perfusion, which of the following statements best reflects the accuracy of subjective assessment of intestinal viability?
🔍 Key Findings
- Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
- PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
- No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
- No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
- Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
- SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
- Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
- No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.

In Thompson 2024 et al., on cyanoacrylate enterotomy sealants, which group had the highest initial leak pressure (ILP)?
🔍 Key Findings
- Highest initial leak pressure (ILP) observed in the handsewn + cyanoacrylate (HS + CE) group: 83.3 ± 4.6 mmHg (p < .001 vs. others).
- Lowest ILP: cyanoacrylate-only group (CE): 18.6 ± 3.5 mmHg.
- No significant MIP difference between handsewn (HSE) and HS + CE groups (p = .19); CE had significantly lower MIP (22.7 mmHg).
- Leak location:
- HSE: 60% from suture holes
- CE: 100% from incisional line
- HS + CE: 60% from incisional line, 40% from suture holes
- Authors conclude cyanoacrylate augmentation significantly increases ILP and could reduce enterotomy leakage risk.

In Huels 2025 et al., on second-generation screw cup THA, which implant component was responsible for most major complications?
🔍 Key Findings
- Total complication rate was 16.7%, with 5/30 hips experiencing major complications, mostly related to the femoral component.
- Cup-associated complications were rare (3.3%), with only one case of acetabular cup luxation attributed to surgical technique rather than implant failure.
- No cases of late aseptic loosening were observed during a median follow-up of 17.5 months.
- Implant stability was attributed to the SCSL's porous, trabecular titanium surface, enhancing osseointegration.
- Three femoral stem fractures occurred in a single dog, leading to implant removal; material testing was not performed.
- Most complications were femoral in origin (6/7), not acetabular, suggesting improved performance of the SCSL.
- Explantation rate was 13% (4/30), but some removals were due to owner preference against revision.
- Subjective functional outcome was full recovery in 26/30 hips, including one with successful revision of stem subsidence.

In Barnes 2024 et al., on knot performance, which was a notable disadvantage of the double forwarder knot?
🔍 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.

In Adair 2023 et al., on PCCLm vs OC in dogs, what was the most common reason for converting PCCLm to OC?
🔍 Key Findings
- PCCLm resulted in significantly fewer postoperative lower urinary tract signs compared to OC (13.0% vs 60.9%, p <.001).
- Incomplete urolith removal was not significantly different between PCCLm and OC (11.4% vs 20%, p = .112).
- PCCLm had significantly shorter anesthesia times than OC when no concurrent procedures were performed (97.5 vs 120 min, p < .001).
- Surgical site infection/inflammation (SSII) rates were low and not significantly different between groups (4.5% PCCLm vs 1.8% OC).
- Dogs undergoing PCCLm were more frequently discharged same-day (84.7% vs 0% in OC), reflecting faster recovery.
- PCCLm had higher intraoperative complication rates (22.1% vs 3.4%), mostly due to incision extension or conversions.
- Time to additional surgery for urolith recurrence was longer in PCCLm dogs (24 vs 11.5 months, p = .004).
- Calcium oxalate uroliths were more prevalent in PCCLm cases, while OC had more struvite or mixed types.

In Canever 2022 et al., on labial flap vascular anatomy, what did angiographic evaluation of feline cadavers reveal about the blood supply to the upper and lower lips?
🔍 Key Findings
- Superior and inferior labial arteries in cats perfuse robust angiosomes, which support musculomucosal axial pattern flaps.
- Cadaver angiography confirmed vascular anatomy, with consistent patterns between sides and among specimens.
- The vascular supply is located primarily in the musculomucosal layer, not the skin, critical for flap viability.
- Flap harvest requires inclusion of the orbicularis oris (± buccinator) muscle to ensure vascular integrity and flap survival.
- Two clinical cases demonstrated successful use of superior and inferior labial musculomucosal flaps for palatal reconstruction with complete flap survival and resolution of clinical signs.
- Intraoperative transillumination aided vessel localization, facilitating surgical planning and flap design.
- No cases of distal flap necrosis or dehiscence occurred, although mild donor site morbidity (lip retraction, mucosal denuding) was noted.
- These flaps offer a valuable option when local tissues are compromised, especially after failed previous repairs or radiation therapy.

In Cantatore 2022 et al., on transanal submucosal resection, which of the following was independently associated with increased recurrence risk following surgery?
🔍 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 Shetler 2022 et al., on radial head OCD, which of the following was reported at the 5-month postoperative follow-up?
🔍 Key Findings
- Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
- Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
- Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
- Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
- Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
- Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
- Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
- The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.

In Welsh 2023 et al., on TTAF fixation methods, which failure mode was **most common** in both groups during mechanical testing?
🔍 Key Findings
- Two-pin fixation had significantly greater strength (639 N) than single-pin fixation (426 N) in TTAF models (p = .003).
- Stiffness was also higher with two-pin constructs (72 N/mm vs 57 N/mm); statistically significant (p = .029).
- Both fixation types withstood loads greater than quadriceps force in dogs at a walk (240 N), indicating clinical viability.
- Failure was most commonly due to pin bending or pullout (82%), with fewer cases of ligament tearing or epiphyseal fracture.
- K-wire insertion angle (KWIA) did not significantly differ between fixation types (p = .13).
- Single larger pins delivered ~68% of the strength and ~83% of the stiffness of two smaller vertically aligned pins.
- Clinical implication: Two vertically aligned pins are biomechanically superior for TTAF fixation in canine models.
- Study used mature cadavers, which may underestimate loads and stiffness compared to immature clinical cases.
