🔍 Key Findings Summary

• Primary 3.5-mm LCP used with short (SWL), medium (MWL), and long (LWL) working lengths
• Addition of orthogonal 2.7-mm LCP resulted in:
  • Significantly higher bending stiffness for SWL, MWL, and LWL (p < 0.0001)
  • Higher torsional stiffness for MWL and LWL (not for SWL)
  • Significantly lower strain across all working lengths in bending (p < 0.01)
• Working length inversely related to construct stiffness and directly to plate strain
• Orthogonal plates eliminated stiffness differences across working lengths in bending
• Suggests orthogonal plates can improve implant fatigue life and allow compensation when short working lengths are unachievable

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
2. Use of fenestration (presence associated with better recovery)
3. Hospitalization duration
4. Imaging modality used
5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

🔍 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.

🔍 Key Findings

• 13 cadaver dogs underwent laparoscopic right lateral liver lobectomy in sternal recumbency using a transdiaphragmatic intrathoracic trocar (ITT).
• All lobectomies were successful, regardless of dog size.
• Median total surgical time: 35.5 min; median lobectomy time: 18.5 min.
• ITT port enhanced visualization and access to hilus.
• No correlation between body weight and hilus access (p = .78).
• Stronger correlation between liver lobe weight and lobectomy time (r = .73, p = .004).
• Complication in 3/13 cases: Loss of insufflation due to balloon-tip port failure and pneumothorax.
• Recommendation: Use a new balloon trocar per case in clinical applications to prevent failure.

🔍 Key Findings Summary

• Lateral humeral condylar fractures = 69.8% of cases; medial = 16.2%; Y/T = 14.0%
• Falls/stairs were the inciting trauma in 45.6% of cases; significantly younger dogs were more likely to fracture after major trauma (p = 0.01)
• Complication rate = 22% (10 major, 20 minor); implant migration and seroma most common
• Fixation method had no significant impact on complication rates (p = 0.87)
• Epicondylar comminution was significantly associated with complications (p = 0.02, OR = 3.27)
• Contralateral intracondylar fissure found in 9.8%, none progressed to fracture during study
• Wide inter-center variation in complication rate (5–62%, p = 0.002)

🔍 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.

🔍 Key Findings Summary

• 48 dogs (60 stifles) underwent custom 3D-printed TRP implantation for patellar luxation
• 24 treated with TRP alone; 36 with additional procedures (e.g., DFO, TTT)
• Success rate: 59/60 corrected patellar tracking
• Functional outcome: 57/60 full function, 2 acceptable, 1 unacceptable
• Complication rate: 3 total (2 minor, 1 major recurrence)
• TRP spares cartilage unlike trochleoplasty, offering implant-based ridge augmentation
• No implant loosening or infection observed

🔍 Key Findings

Mortality rate: 36% (12/33)
Cholecystectomy performed: 94% of dogs (31/33)
New significant prognostic factors for survival:

• Hyperbilirubinemia (p = .049) — threshold = 60.5 μmol/L
• Use of vasopressors (p = .002)
• Renal dysfunction postoperatively (p = .008)
• Number of postoperative complications (p = .005)

Multivariate model: Total bilirubin and number of complications best predicted survival
Septic vs nonseptic effusion: No significant difference in survival
Diagnostic imaging: Ultrasound sensitivity for extrahepatic biliary rupture = 38%
Most cultured pathogen: E. coli (80% of septic cases)

🔍 Key Findings

• 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
• Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
• Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
• 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
• Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
• Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
• Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
• Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

🔍 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.
