In Mattioli 2025 et al., on lymphadenectomy complications, what was the most common postoperative complication observed?
🔍 Key Findings
Sample: 201 lymphadenectomies in 163 dogs.
Intraoperative techniques:
- Unassisted: 36%
- Methylene blue (MB): 24%
- Gamma probe + MB (γ-MB): 40%
Complication rate: 7.5% overall (93% uncomplicated)
- 80% were mild, 20% moderate; no severe complications
- Most common = seroma (2.5%), lymphoedema (1.5%)
Risk factors (via decision tree model):
- Surgical time > 21.5 min
- Lymph node site = mandibular or retropharyngeal
No significant difference in complication rate based on:
- Guidance technique (p = .255)
- LN palpability, number removed, or LN size
Clinical implication: Peripheral SLN excision is safe regardless of intraoperative technique; certain sites and durations carry slightly higher risk.

In Barnes 2024 et al., on knot strength testing, which of the following statements is true about unraveling?
🔍 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 Holman 2024 et al., on canine shoulder arthroscopy, what was the main method used to mark the limits of visualization?
🔍 Key Findings
- 48% of the intra-articular biceps tendon was visible at a standing angle; this increased to 63% in flexion (p = 0.0003).

In Meltzer 2022 et al., on femoral implant selection, what was the frequency of catastrophic complications in dogs undergoing THR?
🔍 Key Findings
- Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
- CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
- Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
- No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
- Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
- Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
- Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
- An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.

In Nagahiro 2023 et al., on quadriceps-femoral mismatch, which variables were significantly associated with a decreased QML/FL in the final regression model?
🔍 Key Findings
- Quadriceps muscle length/femoral length ratio (QML/FL) was significantly lower in dogs with grade IV MPL than grades I–III (p ≤ .002).
- Shortened QML was associated with increased femoral torsion angle (FTA) and increased aLDFA, indicating correlation with femoral deformity.
- QML/FL increased with age, possibly due to muscular development or reduced deformity in older dogs (p = .004).
- Grade IV MPL dogs had QML/FL < 0.87, the lower normal limit based on healthy beagles, suggesting clinically significant muscle shortening.
- PLL/PL ratio (used to diagnose patella alta) was not associated with QML/FL or MPL severity in small breeds.
- QML/FL can help preoperatively identify candidates for femoral shortening ostectomy, improving femoropatellar alignment.
- Multivariate regression model confirmed QML/FL is independently influenced by age, FTA, and aLDFA (R² = 0.45).
- CT-based 3D measurements enabled objective, noninvasive quantification of femoral and muscle alignment parameters.

In Low 2024 et al., on TCS for HIF, what was the overall complication rate across all elbows?
🔍 Key Findings Summary
- 47 dogs (57 elbows) underwent TCS placement for HIF
- Overall complication rate = 17.5%
- Minor: seromas (7 elbows)
- Major: septic arthritis (3 elbows) — all resolved with antibiotics
- No screw failures, medial epicondylar fractures, or catastrophic outcomes noted
- Long-term follow-up in 41 dogs (50 elbows):
- 90% full function, 10% acceptable function
- Mean follow-up = ~2.5 years
- Increased age was significantly protective (p = 0.0051; OR = 0.61)
- TCS placement method (freehand, guide, aiming device) significantly impacted screw angulation but not complication rate
- Outcome not affected by presence of complications

In Miller 2024 et al., on staple vs. hand-sewn feline GI techniques, which construct had equivalent leak pressure to hand-sewn anastomosis but with significantly reduced completion time?
🔍 Key Findings
- Skin staple anastomosis (SSA) had comparable leak pressures to hand-sewn anastomosis (HSA) but required half the time to complete.
- Skin staple enterotomy (SSE) had significantly lower leak pressures than hand-sewn enterotomy (HSE) and failed in 12/20 constructs during pressure testing.
- HSE constructs took 8× longer to complete than SSE, but had much higher intraluminal pressure tolerance.
- All SSE constructs leaked from the center, with 35% leaking immediately and 60% showing catastrophic failure.
- SSA leakage occurred at the center in 40% of constructs, likely due to a learning curve in early samples.
- All constructs had higher pressures than normal physiologic intestinal pressure (4.0 mmHg ±2.0), except some SSEs with immediate leaks.
- Authors recommend SSA as a viable alternative with appropriate training but do not recommend SSE using the tested technique in live cats.
- Staple size and placement technique are key factors; smaller or more precisely placed staples may reduce leak risk.

In Gollnick 2024 et al., on TCTF risk with Arthrex STS in TPLO, what was the TCTF rate for STS screws placed distal to the osteotomy?
🔍 Key Findings
- 42% of dogs (33/78) treated with Arthrex 3.5 mm STS during TPLO developed radiographic TCTF
- TCTFs occurred exclusively distal to the osteotomy
- 14% of screws (36/250) distal to the osteotomy were associated with TCTFs
- 6% of dogs with TCTFs developed major complications (e.g., complete tibial fracture requiring surgical revision)
- Angulation of cortical STS screws, especially in the distal plate holes, was a key contributor to complications
- Locking screws were also involved, but cortical screws angled improperly were overrepresented in serious outcomes
- Revision recommendations included preemptive fixation for large TCTFs or angulated screw placements
- Use of non-self-tapping screws (NSTS) previously showed a <1% TCTF rate, supporting higher risk with STS

In Moore 2023 et al., on Divisional outcomes in canine liver mass resection, right divisional liver masses were significantly associated with which intraoperative issue?
🔍 Key Findings
- Liver masses were most common in the left division (58%), followed by central (27%) and right (15%).
- Right divisional masses were significantly associated with intraoperative complications (33% vs 5.6% left, p = .0037), particularly hemorrhage and injury to major vessels.
- Mortality rate was 6.5% overall, with no significant association with liver lobe location.
- Postoperative complications occurred in 28.7% of cases, but were not significantly associated with mass location.
- Thoracic incision extension (sternotomy or diaphragmotomy) increased odds of postoperative complications by 9.1x (p < .001).
- Use of TA stapler significantly reduced both intraoperative (OR 19x lower) and postoperative complications (OR 4.4x lower) vs other methods.
- Specialist surgeons and heavier dogs had significantly fewer postoperative complications.
- Right lobectomies often required thoracic extension, indirectly linking them to increased postoperative morbidity.
