In Scheuermann 2023 et al., on femoral MIPO alignment, what was a noted limitation of the prototype FRS?
🔍 Key Findings
- Precontoured plates using 3D-printed femoral models achieved near-anatomic alignment in all cadaver limbs.
- Fracture reduction system (FRS) required significantly fewer fluoroscopy images than intramedullary pin (IMP) methods (7 vs 26, P = .001).
- Despite longer surgical time (43 vs 29 minutes, P = .011), FRS showed equally accurate or better alignment compared to IMP.
- Femoral length, frontal, sagittal, and axial alignment were all within near-anatomic thresholds (<10 mm or <5° deviation) in both groups.
- FRS was associated with more consistent length maintenance, with IMP showing a median shortening of 2.3 mm (P = .03).
- Axial plane deviation was statistically different in the FRS group (P = .04), but still clinically acceptable.
- Study highlights potential for custom 3D-printed guides to reduce radiation exposure and improve precision in MIPO procedures.
- Authors caution that FRS was time-consuming and cumbersome, suggesting design refinements needed for clinical use.

In Lederer 2025 et al., on MIPO vs ORPS, which surgeon-related variable significantly influenced fixation technique choice?
🔍 Key Findings
Study size: 105 dogs (73 ORPS; 32 MIPO)
MIPO vs ORPS differences:
- Surgical time: MIPO median 130 min vs ORPS 85 min (p < .001)
- Explant rate: MIPO 25% vs ORPS 4.1% (p = .003)
- Time to clinical union: MIPO 85 days vs ORPS 57 days (p = .010)
- Frontal alignment deviation: MIPO 3.5° vs ORPS 2.0° (p = .047)
- Comminution more frequent in MIPO (41% vs 16%; p = .012)
Significant predictors for MIPO use: More proximal fracture margin (p = .004), surgeon identity (p < .001)
No significant difference: Sagittal alignment, radial length, union rate, or complication rate by surgeon
Implant preference: Fixin plates used in 84% of MIPO; locking plates more common in ORPS

In Oramas 2025 et al., on laparoscopic liver lobectomy, what was the median total surgical time?
🔍 Key Findings
- 13 cadaver dogs underwent laparoscopic right lateral liver lobectomy in sternal recumbency using a transdiaphragmatic intrathoracic trocar (ITT).
- All lobectomies were successful, regardless of dog size.
- Median total surgical time: 35.5 min; median lobectomy time: 18.5 min.
- ITT port enhanced visualization and access to hilus.
- No correlation between body weight and hilus access (p = .78).
- Stronger correlation between liver lobe weight and lobectomy time (r = .73, p = .004).
- Complication in 3/13 cases: Loss of insufflation due to balloon-tip port failure and pneumothorax.
- Recommendation: Use a new balloon trocar per case in clinical applications to prevent failure.

In McLean 2024 et al., which variables were found to have no significant association with rock-back?
🔍 Key Findings Summary
- 95 TPLO procedures reviewed retrospectively with follow-up radiographs
- Rock-back defined as increase in tibial plateau angle (TPA) ≥2° from immediate post-op to recheck
- 21% of stifles (20/95) experienced rock-back
- Mean ΔTPA among rock-back cases = 3.2° ± 2.6°
- No implant failures or tibial tuberosity fractures were reported in these cases
- Plate inclination and exit cut angle (ECA) were not associated with increased risk of rock-back (p = 0.4 and 0.2)
- Authors hypothesize that compression across osteotomy in vivo may mitigate torsional effects from ECA, unlike in gap-model studies
- Emphasizes that rock-back is relatively common, even with well-placed implants

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 Zann 2023 et al., In Long-term outcomes after proximal humeral OC debridement in dogs, what difference was noted in affected limbs compared to contralateral limbs in unilaterally affected dogs?
🔍 Key Findings
- 20 dogs (26 shoulders) evaluated at mean 3.5 years post-surgery after arthroscopic or open debridement.
- Ipsilateral muscle atrophy and decreased range of motion (↓ extension, ↓ flexion) in affected limbs compared to contralateral healthy shoulders.
- All treated shoulders developed osteoarthritis, confirmed radiographically, by CT, and arthroscopically.
- Moderate to severe synovitis was present in all shoulders; lesions showed patchy, incomplete cartilage infilling even up to 8.9 years post-op.
- Kinetic gait analysis showed no significant differences in PVF/VI between affected and unaffected limbs, despite mild lameness clinically.
- Owners reported good to very good mobility (median LOAD = 6), often underestimating clinical lameness.
- CT detected larger lesion dimensions than radiographs (wider, deeper defects).
- Despite progression of OA, surgical debridement was associated with satisfactory long-term function, though not prevention of degenerative changes.

In Chen 2024 et al., on pressure-measurement tools, why is high precision potentially more critical than accuracy when monitoring portal pressures during PSS ligation?
🔍 Key Findings
- WMg (water manometer with gauge) was the most accurate and precise pressure measurement device.
- APT (arterial pressure transducer) was less accurate than WMg but still precise; it differed significantly from the gold standard (WMr).
- CCT (Compass CT) was the least accurate and precise and differed significantly from the set pressure.
- Mean differences from set pressure were smallest for WMg (−0.020 cm H2O), moderate for APT (−0.390 cm H2O), and largest for CCT (−1.267 cm H2O).
- All devices showed excellent interobserver (ICC = 1.000) and intraobserver agreement (ICC range 0.985–0.998).
- Even though the CCT performed least well, all devices had mean errors ≤1.3 cm H2O, indicating potential clinical utility.
- WMg or WMr should be preferred in surgical settings due to superior accuracy and precision.
- Measurement precision is more critical than accuracy during PSS surgery, as a 1 mm Hg (~1.3 cm H2O) increase in portal pressure raises odds of poor outcomes by 9%.

In Timmermans 2026 et al., on soft palate changes post-BOAS surgery, which of the following best describes the rostral thickness (RTH) outcome in both treatment groups?
🔍 Key Findings
- Soft palate length, volume, and cross-sectional area decreased significantly after both folded flap palatoplasty (FFP) and standard staphylectomy (STS).
- Middle thickness (MTH) of the soft palate decreased after STS but increased after FFP, indicating FFP may not thin the soft palate long-term.
- Rostral thickness (RTH) increased in both groups, suggesting regional variation in healing or remodeling.
- Clinical improvement (exercise tolerance) occurred in most dogs: 6/8 in FFP and 10/10 in STS group.
- One major complication in FFP group led to death despite revision surgery; another mortality occurred in STS group (likely due to severe laryngeal collapse).
- No difference in minor complication rates between FFP and STS groups.
- Histological remodeling or edema may explain lack of MTH reduction in FFP at 3 months.
- Immediate postoperative imaging may be needed to evaluate initial reduction effects of FFP.

In Fink 2025 et al., on Roux-en-Y outcomes, which complication had the **lowest** reported incidence?
🔍 Key Findings
- Roux-en-Y procedures were successfully completed in all 11 cases (6 dogs, 5 cats), despite case complexity and disease severity.
- Median survival post-discharge was longer in cats (365 days) vs. dogs (82 days), with better outcomes in non-neoplastic vs. neoplastic disease (192 vs. 5 days).
- Complication rate was high, with septic peritonitis, dehiscence, and cardiac arrest as leading causes of postoperative death; mortality rate = 36%.
- Dehiscence rate was 8.6% (2 of 23 anastomoses), considered lower than typical rates for GI anastomoses in high-risk patients.
- Feeding tubes (gastrostomy/jejunostomy) were used in all cases, enabling early nutritional support and stomach decompression.
- Postoperative nausea and vomiting were common but mostly self-limiting; managed with metoclopramide, cisapride, and antiemetics.
- Choledochojejunostomy was preferred when common bile duct was dilated, offering a favorable size match and potentially reducing bile leakage.
- Roux-en-Y reduced typical Billroth II complications (e.g., bile reflux, afferent loop syndrome, dumping syndrome), with none observed in discharged patients.

In Buote 2023 et al., on laparoscopic vertical sleeve gastrectomy (LVSG), on LVSG, what percentage of the stomach was resected by weight in cadaveric specimens?
🔍 Key Findings
- LVSG was successfully performed in 9/10 cadavers and both live cats, demonstrating procedural feasibility.
- Mean stomach resected was 27.6% of total weight in cadavers, with no leaks in 8/8 tested or either live patient.
- Mean surgical time: 110.4 min (cadavers) and 115 min (live cats); no intra- or postoperative complications observed.
- Stenosis near the incisura occurred in 2 cadavers; attributed to staple placement too close to the lesser curvature.
- 3D printed cannulas (3DPCs) improved ergonomics and were used in 6/10 cadavers and both live procedures.
- Live cats lost 21–24% body weight over 3 months, with full return to pre-surgical BCS and no GI complications.
- Orogastric tube and proper tensioning were critical in preventing gastric stenosis during staple placement.
- No reinforcement or oversew was used on the staple line; TriStaple cartridges provided reliable closure.
