In Weaver 2026 et al., on Endo GIA stapler outcomes, which feature of the Endo GIA stapler distinguishes it from traditional TA staplers during lung lobectomy?
🔍 Key Findings
- Endo GIA staplers were successfully used in 46 lung lobectomies across 37 cases, including 33 dogs and 4 cats, representing the first in vivo clinical report of this stapler for open thoracic lung lobectomy.
- Most procedures had no intraoperative complications (82.6%), while minor complications occurred in 17.4%, primarily mild hemorrhage or air leakage.
- No major intraoperative complications were reported, and postoperative catastrophic events occurred in 4/37 cases (10.8%), likely related to underlying comorbidities rather than stapler failure.
- Short-term outcomes were excellent, with 97% of cases completing 14-day follow-up without complications aside from one seroma.
- Common indications for lung lobectomy included pulmonary masses, pulmonary bullae, abscess/granuloma, lung lobe torsion, trauma, and spontaneous pneumothorax.
- Endo GIA staplers provide simultaneous stapling and cutting, with articulation and 360° axial rotation, improving maneuverability in confined thoracic cavities.
- Tri-Staple technology deploys three staggered staple rows, which may improve sealing, reduce air leakage, and maintain tissue perfusion at the staple line.
- Overall complication rates were low, supporting the Endo GIA stapler as a safe alternative to traditional TA staplers for open lung lobectomy procedures.

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 Mazdarani 2025 et al., on simulated muscle loading, what design feature made Model 3 more favorable for research use over Model 1?
🔍 Key Findings
- Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
- Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
- Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
- Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
- Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
- Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
- Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
- The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

In Cruciani 2022 et al., on feline pancreaticoduodenostomy, what complication did *not* occur during the follow-up period?
🔍 Key Findings
- Left pancreaticoduodenostomy successfully restored digestive continuity after right lobe and body pancreatectomy in a cat.
- No clinical signs of exocrine or endocrine insufficiency were observed postoperatively up to 225 days.
- Histopathology confirmed chronic pancreatitis with abscess formation and reactive lymphadenopathy.
- No postoperative pancreatitis developed, based on imaging and normal feline pancreatic lipase levels.
- Progressive focal ampulla-like dilation of the pancreatic duct occurred near the anastomosis without clinical signs.
- The cat maintained weight and improved clinically for several months post-op, indicating satisfactory outcomes.
- Surgical technique involved end-to-side anastomosis between the left pancreatic duct and duodenum.
- Ultimately, the cat was euthanized due to disseminated carcinoma, presumed unrelated to the pancreatic surgery.

In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), which imaging modality identified TPPs in all cases?
🔍 Key Findings
- Traumatic pulmonary pseudocysts (TPP) were diagnosed in 11 patients (9 dogs, 2 cats) using CT after blunt trauma.
- TPPs were identified on radiographs in 64% of cases that were CT-confirmed, highlighting the superior sensitivity of CT.
- Most cases (7/10) were managed conservatively, with complete recovery and no TPP-related mortality.
- Thoracic surgery (lung lobectomy) was performed in 3 dogs, due to persistent pneumothorax or large TPP with perceived risk of complications.
- All pneumothorax cases were managed with thoracostomy tubes, and chest drains were used in 73% of cases.
- Pneumothorax was present in 100% of patients, often bilateral, and pulmonary contusions were reported in 73%.
- One cat was euthanized due to unrelated maxillofacial trauma; no deaths were attributed to TPP itself.
- Long-term follow-up (median 768 days) revealed only 1 case with possible TPP-related pneumonia; others had no complications.

In Foster 2026 et al., on right hepatic lobectomy, which surgical method was associated with increased complication risk?
🔍 Key Findings
- Perioperative mortality rate was low (2.9%), with no intraoperative deaths reported.
- Intraoperative complications occurred in 54.3% of dogs, most commonly hemorrhage and cardiovascular events.
- 21% of dogs required blood transfusions, though transfusion was not associated with higher complication risk.
- Advanced hemodynamic support (fluid + cardiovascular) was significantly associated with short-term complications (OR 17.3, p = .029) and shorter survival.
- No surgical method (e.g., TA stapler, vessel sealing device, hilar resection) was associated with increased risk of complications.
- Hepatocellular carcinoma (HCC) was the most common diagnosis (53%), with an MST of 741 days and 17.6% recurrence.
- Surgical margins (complete vs incomplete) were not associated with overall survival time in dogs with HCC.
- The use of preoperative CT and improved surgical instrumentation may have contributed to the lower observed mortality.

In Peterson 2022 et al., on crescent guide in TPLO, what was the primary benefit observed in novice surgeons using the crescent guide over other devices?
🔍 Key Findings
- Crescent guide use resulted in significantly less medial cortical damage (mean 3.8 mm²) than the radial saw guide (35.7 mm²) and standard jig (51.3 mm²) in bone models.
- No significant difference in osteotomy accuracy (distance of eccentricity, coronal or axial angulation) among crescent guide, radial guide, or standard jig in either bone models or cadavers.
- Device application time was shortest with the crescent guide and longest for the radial saw guide.
- Osteotomy time was fastest with the crescent guide compared to the radial saw guide (P = .015).
- Participants rated the crescent guide easier to apply than both the radial saw guide (P < .005) and the standard jig (P = .015).
- 5 of 6 novice participants preferred the crescent guide over the other devices for performing TPLO.
- Subjective ease of osteotomy performance was higher with the crescent guide vs. radial guide (P < .001).
- Crescent guide does not assist in fragment stabilization or plateau rotation unlike a standard TPLO jig.

In Sullivan 2025 et al., on TTT stabilization methods, what biomechanical benefit did the TBW group demonstrate over the others?
🔍 Key Findings
- Spacer pin fixation showed no difference in failure force or stiffness compared to tension band wire (TBW) or 2-pin techniques.
- All constructs failed under loads >1000 N, exceeding estimated peak quadriceps force in dogs during walking (~240 N).
- Patellar ligament failure was the most common mode of failure across all groups (5–8 samples per group).
- Distal tibial crest fractures were seen only in 2-pin and spacer pin groups, not in TBW group, suggesting TBW may protect against crest failure.
- No failures occurred at pin tracts, possibly due to pin placement within patellar ligament footprint.
- Spacer pin technique avoids placing pins through the tuberosity, potentially reducing risks of soft tissue complications like tendinopathy or irritation.
- Use of partial osteotomy with robust distal crest may substitute for TBW without compromising initial mechanical strength.
- Further in vivo or cyclic loading studies are required, as this cadaveric study tested only acute tensile failure.
