🔍 Key Findings

• Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
• Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
• Bone union was achieved in all cases post-DFSO, indicating good healing potential.
• Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
• One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
• DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
• Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
• DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

🔍 Key Findings

• Left pancreaticoduodenostomy successfully restored digestive continuity after right lobe and body pancreatectomy in a cat.
• No clinical signs of exocrine or endocrine insufficiency were observed postoperatively up to 225 days.
• Histopathology confirmed chronic pancreatitis with abscess formation and reactive lymphadenopathy.
• No postoperative pancreatitis developed, based on imaging and normal feline pancreatic lipase levels.
• Progressive focal ampulla-like dilation of the pancreatic duct occurred near the anastomosis without clinical signs.
• The cat maintained weight and improved clinically for several months post-op, indicating satisfactory outcomes.
• Surgical technique involved end-to-side anastomosis between the left pancreatic duct and duodenum.
• Ultimately, the cat was euthanized due to disseminated carcinoma, presumed unrelated to the pancreatic surgery.

🔍 Key Findings

• Patient-specific 3D-printed PCL/β-TCP scaffold enabled successful zygomatic arch reconstruction in a dog.
• Complete surgical resection of a zygomatic parosteal osteosarcoma was achieved, with a 0.3 mm histologically clean margin.
• Post-op imaging showed progressive tissue ingrowth into the scaffold, with Hounsfield Units increasing from 20.4 to 97.8 over 10 months.
• No complications (e.g., infection, displacement) or tumor recurrence were noted at 16-month follow-up.
• Use of a patient-specific osteotomy guide improved anatomical fit and facilitated precise excision and implant placement.
• Facial symmetry and orbital stability were maintained throughout follow-up.
• The scaffold remained structurally stable despite limited bone regeneration, suggesting connective tissue filled the defect.
• Topical mitomycin C was applied intraoperatively for possible anti-neoplastic effect, but efficacy remains unclear.

🔍 Key Findings

Synovitis was present in 100% of canine stifles with CCL disease (n = 163).

The most frequent severity score was 3/5 (55.2%), followed by 4/5 (24.5%).

Higher synovitis scores were significantly associated with:

• Higher median cartilage scores (p = .042, OR = 2.1 per unit increase)
• Longer duration of clinical signs (p < .001, OR = 1.27 per month)

Bodyweight (p = .083) and sex (p = .17) were not statistically significant in multivariable analysis.

Bucket handle meniscal tears were not associated with synovitis severity.

Clinical implication: Earlier intervention may help reduce synovitis and slow OA progression.

🔍 Key Findings

• Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
• UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
• UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
• Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
• No suture breakage or urethral narrowing occurred in either group.
• Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
• Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
• UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.

🔍 Key Findings

• 67.9% of respondents reported using SSCs, with most indicating frequent use (64% used in every surgery).
• 78.7% agreed SSCs reduce complications, and 89.6% believed SSCs improve communication.
• Respondents not using SSCs were more likely to view them as a waste of time (p < .001).
• Forgetfulness (39.6%) and time constraints (36.5%) were leading reasons for checklist noncompletion.
• Only 23.3% had SSC training during surgical residency, with newer diplomates more likely to have had exposure (p < .001).
• Key strategies to improve uptake included: staff feedback modifications (67.9%), formal designation of initiator (48.6%), and training (52.2%).
• Surgeons and OR staff were most commonly identified as noncompliant team members.
• SSC use was more frequent in small animal practices, and mandating SSCs by management was favored but not always effective alone.

🔍 Key Findings

• DPO significantly improved femoral head coverage, increasing mean DLS from 36.1% to 71.4% postoperatively (p < 0.001).
• No significant change in DLS between immediate postoperative and follow-up scans, suggesting stable surgical outcomes over time.
• Greater plate angle (30°) yielded larger DLS improvement (mean increase: 39.8%) compared to 25° and 20° plates.
• Only 3 hips had post-op DLS scores <55%, indicating most patients had lower risk of osteoarthritis progression.
• No correlation found between DLS improvement and age, body weight, or side of surgery, suggesting broad applicability.
• CT was used for DLS measurement in simulated weight-bearing, improving precision over radiographic methods.
• Major limitations included small sample size, multiple surgeons, and variable sedation vs anesthesia during imaging.
• DPO confirmed as effective for reducing dorsolateral subluxation, improving coxofemoral joint congruency in dysplastic dogs.

🔍 Key Findings

• Modified prepubic urethrostomy (mPPU) was effective for managing proximal urethral obstructions in male cats.
• All 8 cats regained voluntary urination within 24 hours postoperatively.
• Early urinary incontinence and peristomal dermatitis occurred in all cats but were self-limiting.
• Two cats (25%) required surgical revision due to stomal obstruction from weight gain and abdominal fat.
• No intraoperative complications were reported in any of the 8 cats.
• Follow-up (13–84 months) showed sustained urinary continence and owner satisfaction in all cases.
• The rectus abdominis muscle tunnel likely increased outflow resistance, minimizing persistent incontinence.
• Recurrent hematuria and dysuria occurred in 3 cats but were managed conservatively.

🔍 Key Findings

• 3D-printed patient-specific guides (PSGs) significantly improved accuracy of drill hole entry (p < 0.001) and exit (p = 0.044) compared to commercial aiming devices (AD).
• Zero joint penetrations occurred with PSGs, whereas 3 of 7 AD-guided screws were predicted to penetrate the joint (p = 0.19).
• Variance in exit point and drill angle was significantly lower in PSG group, suggesting more consistent results.
• One PSG case failed due to improper guide seating, but this was corrected with improved soft tissue clearance.
• PSGs enabled safer trajectories despite use by novice surgeons, emphasizing their value in less experienced hands.
• Drill holes placed with ADs deviated more cranially and distally, increasing the risk of articular violation.
• Use of PSGs allowed for tighter clustering of drill trajectories, especially in the cranial–caudal axis.
• Subjective feedback favored PSGs for ease of use and ergonomic design, despite requiring slightly larger incisions.

🔍 Key Findings

• TA lung lobectomy was feasible in dogs ≥3 kg, including those with lesions up to 10 cm.
• 12 intraoperative complications (40%) occurred, with 6 dogs (20%) converted to open thoracotomy, mainly due to adhesions or inability to isolate lobes.
• Postoperative complications occurred in 8 dogs (27%), most were mild (63%), and only 1 death (3%) was reported.
• Median hospitalization was 47 hours; 29/30 dogs were discharged successfully.
• One-lung ventilation (OLV) was attempted in 7 dogs but successfully maintained in only 4.
• Linear staplers had shorter surgery times (median 57.5 min) than endoscopic staplers (80 min).
• Histopathology confirmed neoplasia in 77% of cases, most commonly papillary and bronchioalveolar carcinoma.
• TA lobectomy allows MIS in smaller dogs or with large lesions, avoiding need for full thoracotomy or complex anesthesia/stapling.
