In Danielski 2025 et al., on PUO complication reduction, what was the **overall complication rate** reported with IM pin and rhBMP-2 use?
🔍 Key Findings
- Combined intramedullary (IM) pin and rhBMP-2 use resulted in a low complication rate (7.4%) after proximal ulnar osteotomy (PUO).
- Major complications occurred in 5.3% of cases (4 infections, 1 pin breakage with ulnar tilt requiring revision).
- Minor complications occurred in 2.1% of cases (seroma, delayed union).
- No cases of non-union were observed; 98.9% of limbs achieved radiographic healing by 6 weeks.
- IM pin breakage was noted in 11.8% of limbs but did not affect healing outcomes.
- Chondrodystrophic breeds made up 64.8% of the cohort and tolerated the procedure well.
- Compared to prior studies, complication rates were substantially reduced with this technique (prior major: 13.9%; this study: 5.3%).
- The use of rhBMP-2 likely enhanced early bone healing and provided biologic support, particularly important in breeds at higher risk of complications.

In Sunlight 2022 et al., on Protein C monitoring, which combination was most associated with “excellent” ultimate clinical status?
🔍 Key Findings
- Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
- Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
- Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
- Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
- Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
- Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
- PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
- Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

In Kuvaldina 2023 et al., on axillary lymph node excision, which complication was NOT observed in any of the clinical cases following axillary lymphadenectomy?
🔍 Key Findings
- Endoscopic excisional biopsy of axillary lymph nodes was successfully performed in cadavers and clinical dogs with minimal complications.
- The technique used a SILS port and CO₂ insufflation through a small incision between the latissimus dorsi and superficial pectorals.
- In 4 cadavers (6 limbs), mean time to remove axillary nodes was 33 minutes, and single nodes were found in 5/6 limbs.
- In 3 clinical dogs, the procedure was successful in 2 cases; 1 required conversion to open surgery due to difficulty manipulating the node.
- Accessory axillary nodes were successfully excised when present, located adherent to deep latissimus dorsi.
- No cases developed lymphedema, pneumothorax, or major complications postoperatively.
- Subjective benefits included better visualization, reduced dissection, and less postoperative morbidity than open techniques.
- Study suggests MIS lymphadenectomy may improve staging accuracy and reduce complications, though larger studies are needed.

In Kuvaldina 2023 et al., in Minimally invasive axillary lymphadenectomy in dogs, which of the following best describes postoperative morbidity in the 3 clinical patients?
🔍 Key Findings
- A minimally invasive endoscopic technique was successfully developed for excisional biopsy of axillary lymph nodes in dogs.
- The procedure was performed on 4 cadavers (6 limbs) and 3 clinical patients, with no major complications reported.
- Mean cadaveric time: accessory axillary node 5.1 min; axillary node 33 min. One limb had a double axillary node.
- In clinical cases, 2/3 were completed endoscopically; one required conversion to open due to node elevation difficulty.
- Surgical times in clinical cases ranged from 35 to 58 minutes, depending on node accessibility and number.
- Postoperative morbidity was minimal: no lymphedema, minor seroma or lameness resolved quickly.
- The SILS port approach enabled effective access, though precise placement was critical to visualization.
- This is the first reported veterinary endoscopic technique for axillary lymphadenectomy; potential for improved staging and reduced morbidity.

In Korchek 2025 et al., on fracture gap risk, what effect did prolonged external coaptation (>1 week) have on outcomes?
🔍 Key Findings
80 toy breed dogs with surgically repaired transverse radius/ulna fractures were analyzed.
Fracture gap in the caudal cortex was present in 46% of cases.
Implant failure rate:
- 27% in cases with fracture gap
- 2% in cases without fracture gap
Fracture gap significantly associated with implant failure:
- OR = 23.0, 95% CI: 2.7–197.9, p = 0.004
Absence of external coaptation also associated with increased implant failure risk:
- OR = 10.1, 95% CI: 1.1–89.6, p = 0.04
Prolonged external coaptation (>1 week) linked to non-implant complications (skin wounds, osteopenia, osteomyelitis):
- OR = 5.4, p = 0.04
Plate thickness, type, open screw holes, and working length were not statistically significant predictors of implant failure after multivariable analysis.

In Thompson 2024 et al., on cyanoacrylate enterotomy sealants, what was the most common leak location in the cyanoacrylate-only (CE) group?
🔍 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 Alvarez-Sanchez 2023 et al., on SLN mapping in canine MCT, what was the histologic metastasis rate (HN2 or HN3) in excised lymph nodes?
🔍 Key Findings
- Combined ICTL and NIRF detected the same SLN in 80% of cases; each method alone missed sentinel lymph nodes in some dogs.
- ICLT failed in 5% of dogs, while NIRF failed in 20%; combined use resulted in only 5% failure in SLN detection.
- Metastatic lymph nodes were detected in 95% of dogs, despite most tumors being low or intermediate grade (95%).
- 27 of 41 nodes (65.8%) were histologically metastatic (HN2 or HN3), many of which would have been missed using ALN alone.
- ALN matched the SLN in only 45% of cases with ICTL and 30% with NIRF, supporting the need for SLN mapping.
- ICLT and NIRF were complementary, often identifying different SLN, with some only fluorescent or enhanced in one modality.
- Subcutaneous MCT had higher metastatic rates (7/8 dogs) than previously reported, challenging older assumptions about benign behavior.
- Removing both ALN and SLN (from both methods) improved detection of metastasis to 85–95%, reducing risk of understaging.

In Wood 2024 et al., on knot security and locking throws, which knot had the poorest performance, especially without a locking throw?
🔍 Key Findings
- Adding a single locking throw significantly increased holding security for specific knots, including the surgeon's throw (p = .0001) and square throw (p = .0002).
- For the Miller's throw (p = .166) and strangle throw (p = .808), no significant improvement was observed with a locking throw.
- After locking throw addition, all five knots leaked at similar pressures (p = .5233), and these pressures exceeded physiologic arterial pressures.
- Surgeon's throw without a locking throw had the lowest leak pressure (62.5 ± 46.2 mm Hg), below physiologic arterial values.
- The square throw without locking also leaked below physiologic pressures (148.7 ± 109.4 mm Hg), though it outperformed the surgeon's throw.
- Miller’s and strangle throws performed significantly better than square or surgeon’s throws without locking, achieving leak pressures >200 mm Hg.
- All knots used 2-0 polyglyconate monofilament (Maxon); no comparisons across suture types or sizes were performed.
- Authors concluded that correct tensioning and locking throw addition are key to safe vascular ligation. Miller’s, strangle, or slip knots are preferred for challenging surgical fields.

In Poggi 2025 et al., on laparoscopic cholecystectomy in cats, what was the reported median postoperative hospitalization duration?
🔍 Key Findings
- Laparoscopic cholecystectomy (LC) was successfully performed in all 22 cats without conversion to open surgery.
- Complication rate was low: 3 cats had postoperative complications (1 seroma, 1 vomiting, 1 EHBDO and death).
- Median operating time was 41 minutes; median hospitalization was 3 days.
- No cases required conversion to open laparotomy, even in cats as small as 2.5 kg.
- Common devices used: Hemoclips or Hem-o-lok for cystic duct ligation; Ligasure, harmonic scalpel, or j-hook for dissection.
- Most common indications: cholelithiasis (9/22) and cholecystitis (10/22), with one biliary mucocele and one adenoma.
- Histopathology confirmed diagnosis in all cases; concurrent liver or intestinal biopsies were performed in some cats.
- Postoperative AUS and bloodwork were routine and important for detecting early signs of EHBDO.

In Duffy 2022 et al., on crotch suture techniques, which statement best describes leakage location outcomes with SCCS?
🔍 Key Findings
- Augmenting FEESA with two simple interrupted crotch sutures (TCS) or simple continuous crotch suture (SCCS) significantly increased initial leakage pressure (ILP) compared to no suture or a single suture (NCS, SICS).
- SCCS had the highest ILP (47.6 mm Hg), followed by TCS (37.8 mm Hg), SICS (33.0 mm Hg), and NCS (27.1 mm Hg).
- All crotch suture types increased maximal leakage pressure (MLP) compared to no crotch suture.
- Leakage from the crotch occurred most commonly in NCS (67%) and SICS (50%), but only 8% with TCS and 0% with SCCS.
- SCCS was the only technique where leakage never occurred at the crotch site.
- SCCS had the highest MLP (100.6 mm Hg), supporting its use in clinical settings with high-risk patients.
- Intraluminal pressures during leakage in NCS constructs were sometimes below normal physiologic pressures, emphasizing risk of leakage without crotch suture.
- The transverse staple line never leaked in any group, indicating the crotch is the primary weak point.
