In Ferreira 2025 et al., on heated pneumoperitoneum in dogs, which of the following correlated with temperature reduction only in the nonheated group?
🔍 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 Glenn 2024 et al., on client-based SSI surveillance, which of the following statements best describes Algorithm 1?
🔍 Key Findings
- Algorithm 3 had the highest overall accuracy (95.5%) in diagnosing SSIs from client questionnaires.
- Active surveillance identified 19.4% more SSIs compared to passive surveillance alone.
- SSI rate was 8.22% across 754 surgeries; 33.9% of SSIs required revision surgery.
- Client-based responses were 37.9% more frequent than those from referring veterinarians.
- Deep/implant SSIs could be missed if not associated with visible wound healing problems.
- Two late SSIs (after 90 days) occurred, both linked to implant surgeries.
- Algorithm 1 was the most sensitive (87.1%) but less specific; useful for screening.
- Algorithm 2 had the highest specificity (97.9%); useful as a “rule-in” diagnostic method.

In Davey 2024 et al., on modified closed anal sacculectomy, what percentage of dogs experienced postoperative complications, and how were most classified?
🔍 Key Findings
- Modified closed anal sacculectomy resulted in a local recurrence rate of only 2.2%, substantially lower than prior reports (18–50%).
- Postoperative complications occurred in 31.9% of dogs; most (93%) were minor, with dehiscence being the most common.
- Mean survival time in deceased dogs was 521 days; median was 388 days.
- Surgical technique included complete en bloc excision of the sac and duct with sphincter reconstruction, aiming to reduce seeding risk.
- Only one major complication resulted in euthanasia due to infection and dehiscence.
- Histologic margins were complete in 44.7% of dogs; lymphatic invasion was present in 31.9%, and vascular in 8.5%.
- Adjunctive chemotherapy was administered in 34% of dogs (mostly carboplatin); not standardized due to retrospective design.
- Routine rectal exam was key to diagnosis in 57.4% of dogs with no clinical signs, underscoring the importance of screening.

In Peng 2025 et al., on topical amikacin gel, at what time point were serum levels consistently above the lower limit of quantification (LLOQ)?
🔍 Key Findings
Objective: Determine if topical 45 mg/mL amikacin in CMC gel leads to systemic absorption in dogs with wounds.
Dogs enrolled: 11 client-owned dogs, with 31 applications of the gel.
Serum findings:
- Only 5 of 153 samples were above the 2.5 µg/mL quantification limit
- All values remained <5 µg/mL, the presumed toxicity threshold
- No correlation was found between dose-related parameters (mg, mg/kg, mg/cm²) and serum amikacin levels
Peak concentrations were observed at ~2 hours post-application, declining rapidly thereafter
No nephrotoxicity observed, and most values were below detection
Conclusion: Topical amikacin gel appears safe at doses up to 24.9 mg/kg, with minimal systemic absorption

In Larose 2024 et al., on laparoscopic liver biopsies in dogs, which artifact was significantly more common in 3 mm biopsy samples compared to 5 mm samples?
🔍 Key Findings
- Histologic agreement between 3 mm and 5 mm biopsies was 90%, with a Gwet's AC1 of 0.81 (p < .0001).
- 5 mm biopsies yielded significantly more portal triads and lobules than 3 mm samples (p = .0003 and p < .0001).
- Crush artifacts were significantly higher in 3 mm samples (p = .035), though fragmentation scores were similar (p = .935).
- Both forceps produced adequate samples for histopathology, copper quantification, and bacterial culture.
- No hemorrhage requiring intervention occurred, and both sizes were deemed safe and minimally invasive.
- Surface area ≥40 mm² strongly predicted ≥11 portal triads, a desirable threshold for reliable histopathology.
- Use of 3 mm instruments was easier in small dogs (<12 kg), but more challenging in larger dogs due to shaft length.
- Clinical diagnoses were unaffected by forceps size, even in the one discordant histologic pair.

In Aertsens 2025 et al., on thoracic lift technique, what was the primary physiologic improvement observed in Cat 1 following lift device application?
🔍 Key Findings
Case 1: Chest wall lift improved oxygenation (PaO₂ increased from 179.4 to 306.3 mmHg) and enabled thoracoscopic-assisted lobectomy in a cat with pleural effusion and pulmonary carcinoma.
Case 2: Chest wall lift using a Steinmann pin allowed 3-port thoracoscopic lobectomy for a bronchial foreign body; no complications observed.
Both cats: Lift increased working space and eliminated need for thoracotomy; no device-related complications.
Pretied ligating loops (PLL) were effective for hilar vessel ligation—preferred over staplers or self-locking ligatures in feline thorax.
Conclusion: Thoracic lift is a novel, minimally invasive method enhancing thoracoscopic procedures in small patients, particularly cats.

In Latifi 2024 et al., on fascial mapping in the canine hindlimb, which major nerve was highlighted as at risk during dissection in the medial thigh region?
🔍 Key Findings
- This anatomical study mapped fascial planes of the canine hindlimb and pelvis to aid superficial tumor resection.
- Type I fascia (discrete sheets) was suitable for deep margins in fascia lata, lateral crus, and gluteal regions.
- Areas with poor or absent fascia included the ischiorectal fossa, femoral triangle, stifle extensor mechanism, and pes.
- Type IV fascia associated with periosteum (e.g., patella, tibial tuberosity) required partial ostectomy for inclusion in surgical margins.
- Nerves at risk during deep dissection included obturator, superficial peroneal, and tibial nerves, particularly in regions with weak fascia.
- In males, bulbospongiosus muscle could act as a fascial plane but dissection was challenging and potentially hemorrhagic.
- In females, constrictor vulvae/vestibulae muscles were tightly associated with mucosa, limiting clean resection options.
- Distal hindlimb resections often lacked a usable fascial plane, suggesting that amputation or adjuvant therapy may be more appropriate.

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 Welker 2024 et al., on thoracic duct anastomosis with MAC device, what complication was noted in two dogs postoperatively?
🔍 Key Findings
- Anastomosis of the thoracic duct (TD) to the intercostal vein (ICV) using a microvascular anastomotic coupler (MAC) was feasible in all 6 healthy dogs
- Immediate postoperative patency was confirmed in all dogs, but only 4/6 had patent anastomoses at 30 days, with 2 failing due to ICV kinking
- Kinking of the ICV near the azygos vein insertion was the primary failure mechanism, likely from MAC malalignment
- No intraoperative or major postoperative complications occurred, though 2 dogs developed mild seromas
- Use of the MAC device simplified microsurgical anastomosis versus hand suturing, especially in the deep thoracic cavity
- Contrast lymphangiography showed faster clearance from the cisterna chyli postoperatively, suggesting effective flow redirection
- Persistent branches of the thoracic duct may impact outcomes, and should be ligated during surgery
- This technique may be a potential novel treatment for idiopathic chylothorax, improving outcomes by reducing collateral flow stimuli
