In Foster 2026 et al., on right hepatic lobectomy, what was the overall perioperative mortality rate in the study population?
🔍 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 Ferreira 2025 et al., on heated pneumoperitoneum in dogs, what was the primary finding comparing heated to nonheated CO₂?
🔍 Key Findings
- Heated CO₂ insufflation reduced perioperative hypothermia during laparoscopic ovariectomy compared to nonheated CO₂.
- Final body temperature was significantly higher in the heated group (36.03°C) than in the nonheated group (34.93°C).
- Temperature reduction correlated with surgical duration only in the nonheated group (p < .05).
- Heated CO₂ delayed temperature drop, occurring after 20 minutes vs. 5 minutes in nonheated cases.
- No significant differences between groups in anesthetic, surgical, or insufflation times.
- All dogs recovered uneventfully and were discharged the same day.
- Heated CO₂ may offer greater benefit in longer procedures or in small-sized dogs prone to hypothermia.
- No adverse effects were attributed to heated gas use in this clinical trial.

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 Sabol 2024 et al., what critical structure was sometimes <1 mm from the pedicle trajectory in large dogs?
🔍 Key Findings Summary
- Evaluated ideal dorsolateral implant trajectories in T1–T13 using CT in 30 dogs across five weight classes.
- Corridor widths were narrowest in the mid-thoracic vertebrae (as little as 1.8 mm) and increased cranially and caudally.
- Allowable deviation angles (ADA) were often very small (as little as 3°), indicating high risk for canal or thoracic structure breach.
- Distances to critical structures (lungs, aorta, subclavian artery, azygos vein) were often <1 mm, even in large dogs.
- Data suggest extreme caution and precision are needed for thoracic vertebral implant placement and support use of navigation or 3D-printed guides.

- In 58.3% (7/12), none of the bacteria from TECA cultures were found at dehiscence.
- Staphylococcus spp. were isolated in 83.3% of dehiscence samples.
- Methicillin resistance was high among Staphylococcus isolates: 80% at dehiscence.
- Antibiotic susceptibility differed in 57% (4/7) of cases where the same bacteria were cultured at both time points.
- TECA cultures were not predictive of bacteria at incisional dehiscence.
- 75% of dogs healed with either medical or surgical management.
Recommendation: Repeat cultures at dehiscence to guide antibiotic therapy.

In Berthomé 2025 et al., on prophylactic fenestration in cervical IVDE, which statement best describes complication rates between PF and non-PF groups?
🔍 Key Findings
- Prophylactic fenestration (PF) significantly reduced recurrence of cervical intervertebral disc extrusion (0% vs. 37.8%, p < .001).
- Surgery time was longer with PF (median 182 vs. 110 min, p = .017), but no difference in perioperative complication rates (PF 16.7%, non-PF 18.9%; p = .838).
- 25% overall recurrence rate, but all recurrences occurred in the non-PF group.
- Medical management was effective in 92.9% of recurrence cases.
- Most PF sites targeted adjacent discs; 88.9% were at adjacent levels, which are common recurrence sites.
- Neurologic outcomes were similar between PF and non-PF dogs post-surgery and at follow-up.
- Fenestration technique (blade vs. burr) not shown to affect outcome but contributed to extended surgical time.
- No major complications or deaths linked directly to PF in initial surgeries.

In Parlier 2024 et al., on insufflation effects on portal pressure in dogs, what insufflation pressure was predicted to induce portal hypertension (>15 mmHg)?
🔍 Key Findings
- Portal pressure increased proportionally with insufflation pressure: 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg.
- Exponential model: average increase of 7.45% per mmHg of insufflation pressure (CI: 4.7–10.2%).
- No systemic hemodynamic adverse effects were observed; MAP remained >60 mmHg throughout.
- Portal hypertension threshold (15 mmHg) predicted at ~6.4 mmHg insufflation pressure.
- No statistical impact from patient weight, pressure-to-weight ratio, or order of insufflation rounds.
- Measurement technique was feasible and safe, with only minor challenges (e.g., catheter kinking).
- The study supports use of the lowest insufflation pressure needed for visualization to avoid portal hypertension.
- Baseline portal pressures returned after desufflation, supporting comparison pre- and post-attenuation.

In Walker 2022 et al., on TPLO mRUST scoring, which minimum score was associated with a 99% likelihood of subjective union?
🔍 Key Findings
- TPLO mRUST scoring showed improved inter-rater reliability (ICC = 0.56) compared to subjective evaluation (Kappa = 0.33).
- Intra-rater reliability was similar for both methods (TPLO mRUST: 0.73, subjective: 0.72).
- TPLO mRUST scores ≥10/12 strongly correlated with radiographic union, as subjectively assessed (99% agreement).
- No significant difference in healing between first and second TPLO sides (P = .09), countering assumptions about load-bearing impact.
- Higher initial lameness scores and younger age were associated with higher TPLO mRUST scores, suggesting more robust healing in those groups.
- Postoperative complications were linked to lower TPLO mRUST scores, indicating impaired healing.
- Medial cortex was excluded from scoring due to plate obstruction, validating use of only 3 cortices for scoring.
- The TPLO mRUST system may standardize healing assessment, reducing subjective bias across specialties.

In Banks 2023 et al., on TECA-LBO in brachycephalic dogs, what was the overall perioperative complication rate and how did it compare between groups?
🔍 Key Findings
- Extreme brachycephalic breeds (EBBs) presented more acutely and at younger ages, most often with neurological signs compared to other breeds.
- Preoperative signs such as facial nerve paresis, vestibular syndrome, and Horner’s syndrome were significantly more common in EBBs.
- EBBs showed more severe imaging findings, including higher rates of otitis interna (46.3% vs. 8.5%) and brainstem changes (17.5% vs. 3%).
- Intraoperative complications were more frequent in EBBs (11.1% vs. 5.3%), but this difference did not reach statistical significance (p = .078).
- Perioperative complication rates did not differ significantly between EBBs and other breeds (23.5% vs. 29.3%).
- Surgical time was significantly longer in EBBs (median 115 vs. 95 minutes; p = .011).
- MRI or combined CT/MRI were more frequently used in EBBs, likely due to the higher prevalence of neurological signs.
- Despite anatomical challenges, complication rates in EBBs were comparable, supporting TECA-LBO safety in these breeds.
