In Tobias 2025 et al., on frontal sinus mucoceles, what was the most common presumed etiology in affected dogs?
🔍 Key Findings
- Frontal sinus mucoceles occurred in young dogs, often linked to prior skull trauma by 10 months of age.
- All dogs presented with expansile, fluid-filled lesions causing facial swelling; CT showed multicentric bone erosion, including the frontal bone and cribriform plate.
- Surgical options included frontal sinusotomy with either sinus lining ablation or re-establishment of nasofrontal drainage, with or without stenting.
- Nasofrontal stenting led to long-term resolution in most dogs, although recurrence occurred in 4/8 dogs, requiring revision surgery in 3.
- Complications were minor and included swelling or nasal discharge; no intraoperative complications were reported.
- Histology confirmed sterile mucoceles with neutrophilic inflammation and mucin, and cultures were negative in all cases.
- Guaifenesin was used postoperatively in several cases to reduce mucus viscosity; its benefit is unproven in dogs but may support drainage.

In Miller 2025 et al., on spinal drill guide accuracy, what software was used to segment canine spines for guide creation?
🔍 Key Findings
- 3D-printed, SOP plate-specific guides enabled safe screw placement from T12–L5 in canine cadavers and models.
- All 140 screw trajectories were classified as Zdichavski Grade 1, indicating optimal placement without vertebral canal breach.
- Screw angles (cranial-caudal and transverse) matched preoperative planning, with no significant deviation.
- Entry/exit point deviations were <1 mm on average, deemed clinically negligible.
- Drill guides were quick to place (<30 sec per vertebra) and improved ease of surgery.
- Plates acted as effective reduction tools, guiding alignment during screw placement in mobile spines.
- Minor technical challenges arose from cadaveric spine mobility, mitigated by sequential screw insertion.
- Technique may enable future use in fracture/luxation reduction, pending further cadaveric and clinical trials.

In Winston 2023 et al., on LES-AS surgery outcomes, what percentage of dogs experienced complications related to gastrostomy tubes?
🔍 Key Findings
- Modified Heller myotomy with Dor fundoplication improved vomiting/regurgitation scores by 180%, QoL by 100%, and owner-perceived body weight by 63% (P < .05).
- 6 of 9 dogs with postoperative VFSS showed objective improvement in gastric filling scores; others remained stable.
- Oral sildenafil was discontinued postoperatively in all dogs, indicating surgical success comparable to medical management.
- 12 of 13 dogs survived to discharge; one dog was euthanized due to aspiration pneumonia postoperatively.
- 50% of dogs experienced gastrostomy tube complications, higher than reported in previous literature.
- Most complications were gastrostomy-tube related, with some requiring surgical correction (e.g., tube migration, leakage).
- Feeding strategies (Bailey chair, elevated bowls) and food consistency (gruel/liquid) remained essential postoperatively to control regurgitation.
- 9 of 11 owners would opt for the surgery again; those who wouldn’t cited risk or lack of efficacy.

In Viljoen 2022 et al., on surgical hand prep protocols, which technique showed significantly lower CFUs at 120 minutes post-gloving compared to ABHR alone?
🔍 Key Findings
- Pre-ABHR hand preparation lowered CFUs at 120 minutes post-gloving compared to ABHR alone (P = .001)
- pH-neutral soap followed by ABHR outperformed ABHR alone despite being nonmedicated (P = .001)
- CHX and BAC prewashes showed better immediate CFU reduction post-preparation than pHN (P = .012)
- No significant difference in total log10 CFU reduction across all four groups over the full surgical period (P = .362)
- Glove perforation in the thumb was a significant contamination factor (P = .036)
- All dogs recovered without surgical site infections, though SSI incidence was not a primary outcome
- Neutralizer validation lacking, so CHX results interpreted cautiously
- Study supports a 1-minute hand wash with pH-neutral soap prior to ABHR as effective and safe

In Anderson 2025 et al., on wound drain configurations, how many wounds achieved ≥95% surface area coverage?
🔍 Key Findings
- Study Design: Cadaveric model using four large-breed dogs with 10x10 cm full-thickness wounds at four locations (shoulder, thorax, flank, thigh).
- Configurations Tested: Diagonal, opposite, parallel, and perpendicular placements of wound infusion catheter and JP drain.
- Fluid Retrieval:
- No significant difference by configuration (p = .92) or location (p = .32).
- Perpendicular configuration had the highest mean retrieval (11.35 mL, 56.8% of instilled volume).
- Flank location had the lowest retrieval (7.2 mL, 35.9%).
- Surface Area Coverage:
- Parallel configuration achieved the highest SA coverage (83.4% ± 11.6%, p < .01).
- Perpendicular was lowest.
- Leakage:
- No difference in leakage between configurations (p = .74) or locations (p = .10).
- Leakage commonly occurred at drain or catheter entry points (93.8% of wounds).
- Conclusion: Parallel drain configuration optimized fluid dispersion. Infusion-retrieval systems may allow for topical therapy delivery in closed wounds.

In Moore 2023 et al., on Divisional outcomes in canine liver mass resection, what impact did TA stapler use have on surgical outcomes in liver mass resection?
🔍 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.

In Scheuermann 2024 et al., on 3D-printed reduction systems, which limitation was acknowledged as impacting surgical scheduling in the 3D-MIPO group?
🔍 Key Findings
- The study was a historic case-control trial comparing custom 3D-printed VSP-guided MIPO (3D-MIPO) to conventional MIPO (c-MIPO) in dogs with diaphyseal tibial fractures.
- Surgical time was significantly shorter in the 3D-MIPO group (117 min vs. 151 min; p = .014), and fluoroscopy use was dramatically reduced (11 vs. 37 images; p < .001).
- All 3D-MIPO reductions were acceptable or near-anatomic; 2 c-MIPO dogs had unacceptable reductions.
- Tibial length, frontal, and sagittal alignment post-op were similar between groups; no significant difference in anatomic restoration (p > .1).
- Radiographic union occurred in all dogs by 3 months. Time to union was similar between groups (3D-MIPO: 67 days vs. c-MIPO: 53 days; p = .207).
- Postoperative complication rate was higher in 3D-MIPO (27% vs. 14%), including 2 major infections requiring implant removal.
- 3D-MIPO required more pre-op time (~23 hours longer from presentation to surgery; p = .002), partly due to guide printing/sterilization.
- Improved surgical efficiency and more consistent reductions were noted in the 3D-MIPO group, supporting its clinical utility despite increased pre-op logistics.

In Williams 2024 et al., on adrenaline use in maxillary nerve blocks, what adverse cardiovascular effects were observed due to adrenaline?
🔍 Key Findings
- The addition of adrenaline (0.00198%) to bilateral maxillary nerve blocks significantly reduced intraoperative hemorrhage in dogs undergoing sharp staphylectomy (median reduction: 77.1%).
- Normalized hemorrhage (g/kg) and total hemorrhage (g) were significantly lower in the adrenaline group (p = .021 and p = .013, respectively).
- Surgeon-assessed hemorrhage scores were also significantly lower in the adrenaline group (median 2 vs. 3; p = .029), indicating improved surgical visibility.
- No adverse effects (e.g. tachycardia, arrhythmia, or hypertension) were observed with adrenaline administration.
- A standardized intraoral approach to the maxillary nerve block was used with 0.5 mL per side regardless of dog size.
- Breed effect observed: English Bulldogs had higher normalized hemorrhage, possibly due to anatomical variation or underdosing relative to size.
- Adrenaline may also prolong local anesthetic action and reduce blood aspiration risks, though this was not directly measured.
- The study supports the routine inclusion of adrenaline in maxillary nerve blocks for staphylectomy in BOAS patients to improve surgical field and reduce bleeding.
