In Dobberstein 2024 et al., on liver biopsy forceps, what was the mean number of hepatic lobules retrieved with 5 mm forceps?
🔍 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 Duffy 2022 et al., on barbed suture oversew, what was observed regarding leakage through **suture holes in barbed suture constructs**?
🔍 Key Findings
- Oversewing the transverse staple line using barbed suture showed no difference in initial (ILP) or maximum leakage pressure (MLP) compared to monofilament suture (p = .439 and .644).
- Barbed suture repairs were ~18% faster (25 seconds faster; p < .001) than monofilament suture.
- No difference was found between unidirectional and bidirectional barbed sutures in leakage resistance or repair time (p = .697).
- Mean ILP and MLP were significantly higher in control jejunal segments (6.6x and 5.1x greater respectively; p < .001).
- Leakage consistently occurred at the crotch of the FEESA in all oversew groups (>80%), not the staple line.
- All oversewn techniques leaked at supraphysiologic pressures, indicating clinical safety against in vivo leakage.
- No leakage was observed from barbed suture holes, addressing concerns of tissue trauma due to barb design.
- The study supports barbed suture as a viable alternative to conventional monofilament suture for FEESA oversew in dogs.

In Welker 2024 et al., on thoracic duct anastomosis with MAC device, what surgical consideration is recommended to improve outcomes?
🔍 Key Findings
- Anastomosis of the thoracic duct (TD) to the intercostal vein (ICV) using a microvascular anastomotic coupler (MAC) was feasible in all 6 healthy dogs
- Immediate postoperative patency was confirmed in all dogs, but only 4/6 had patent anastomoses at 30 days, with 2 failing due to ICV kinking
- Kinking of the ICV near the azygos vein insertion was the primary failure mechanism, likely from MAC malalignment
- No intraoperative or major postoperative complications occurred, though 2 dogs developed mild seromas
- Use of the MAC device simplified microsurgical anastomosis versus hand suturing, especially in the deep thoracic cavity
- Contrast lymphangiography showed faster clearance from the cisterna chyli postoperatively, suggesting effective flow redirection
- Persistent branches of the thoracic duct may impact outcomes, and should be ligated during surgery
- This technique may be a potential novel treatment for idiopathic chylothorax, improving outcomes by reducing collateral flow stimuli

In Knudsen 2024 et al., on CTA diagnosis, what was the approximate percentage of menisci correctly classified in second readings?
🔍 Key Findings
- Multidetector CTA had high sensitivity (up to 100%) and specificity (up to 96%) for detecting medial meniscal tears in dogs.
- Observer experience significantly influenced diagnostic accuracy, with more experienced observers showing higher agreement and better performance.
- Training effect was evident, as less experienced observers improved between first and second readings.
- Positive likelihood ratios ≥4.6 and negative likelihood ratios ≤0.08 were observed, suggesting CTA is clinically useful for confirming or ruling out meniscal injury.
- CTA allowed identification of full and partial thickness lesions, with good visualization in sagittal, transverse, and frontal reconstructions.
- Approximately 90% of menisci were correctly classified in second readings.
- No adverse reactions were noted from the contrast injection; sedation was used instead of general anesthesia.
- CTA was less invasive and potentially more cost-effective compared to arthroscopy, especially in settings without MRI access.

In Jeon 2025 et al., on distal femoral shortening, which **complication was observed intraoperatively** during the THR procedure?
🔍 Key Findings
- Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
- Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
- Bone union was achieved in all cases post-DFSO, indicating good healing potential.
- Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
- One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
- DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
- Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
- DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

In Payne 2024 et al., on HIF propagation pattern, which variable showed a linear increase with percentage of HIF (%HIF)?
🔍 Key Findings Summary
- HIF typically originates 57° caudal to the supratrochlear foramen and propagates cranially in a segmental pattern.
- %HIF correlated significantly with both fissure depth and length:
- %DHIF increased linearly (r = 0.989, p < 0.001)
- %LHIF followed a sigmoidal relationship with %HIF (p < 0.001)
- Higher %HIF was significantly associated with:
- Clinical lameness (p = 0.004)
- Distal shift in the fissure center (CHIF)
- Implant complications in 5/17 elbows treated with transcondylar screws
- Isthmus diameter increased with weight (p = 0.002), relevant for screw sizing

In Aly 2024 et al., on simulator training for feline OHE, what recommendation do the authors make regarding simulator training?
🔍 Key Findings
- This study evaluated whether high-fidelity surgical simulator training improved live animal and student outcomes in a feline OHE teaching lab involving 186 cats and 146 students.
- Simulator training significantly improved surgical performance and outcomes:
- Live surgery was 6 minutes shorter on average in the SIM group vs. NO-SIM (115 ± 21 min vs. 121 ± 16 min, p = .04).
- Pain scores ≥5/20 occurred in 1% of SIM group cats vs. 15% of NO-SIM group cats (p < .01).
- Rescue analgesia was needed less frequently in the SIM group (5% vs. 15%, p = .03).
- Student confidence was significantly higher in the SIM group (median 7/10 vs. 6/10, p < .01).
- The simulator used a realistic abdominal model with friable tissues and required performance of a full OHE procedure.
- The study design was nonrandomized, grouped by class year, with limitations including lack of blinding during pain assessment in year two.
- Authors concluded that pre-lab simulator competency improves both animal welfare and student confidence, recommending it as a prerequisite for live surgical training.

In Petchell 2025 et al., on CORA-based CCWO, how did small-breed dogs respond to increasing MAA from 3° to 5° in CCWOCORA planning?
🔍 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.
