🔍 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

• FGPP (fluoroscopic-guided percutaneous pinning) resulted in successful healing in 10/13 fractures, with good limb function.
• Complications occurred in 5 of 11 cases, including intra-articular implants, malunion, implant failure/nonunion, and implant migration.
• Cases with delayed surgery (>15 days) or radiographic remodeling were more likely to experience major complications.
• Most fractures (10/13) were classified as Salter-Harris type I with mild displacement.
• Median surgical time was 60 minutes, and no conversions to open surgery were needed.
• Postoperative femoral neck resorption was minimal, suggesting possible benefits of the minimally invasive approach for preserving vascular supply.
• One intra-articular pin led to progressive joint disease and required femoral head ostectomy.
• FGPP appears best suited for acute, minimally displaced fractures in young dogs (<8 months) with planned elective explant to avoid growth disturbance.

🔍 Key Findings

• MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
• Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
• MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
• Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
• MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
• Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
• Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
• The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.

🔍 Key Findings

• Only 2 of 10 PET implants were fully intact and functional at 6 months post-op.
• Owner-reported function (LOAD scores) improved by 51.7% (p = .008) over 6 months.
• Gait asymmetry improved by 86% (p = .002) postoperatively.
• Implant failure occurred in the midbody of the PET device, suggesting fatigue as a failure mechanism.
• One dog (10%) developed implant infection, necessitating implant removal.
• Implant fixation method (screws + washers + interference screw) was mechanically adequate and technically simple.
• Partially intact implants (4/10) still showed improved clinical outcomes, despite structural compromise.
• Midbody tearing and lack of long-term integrity prohibit continued use of this PET implant in CCL repair.

🔍 Key Findings

• 63 dogs ≥15 kg with single EHPSS were reviewed.
• Most common breeds: Golden Retriever (28.6%), mixed breed (20.6%).
• Most common shunt types: splenocaval (25.4%) and portocaval (25.4%).
• 45 dogs received surgical attenuation; 18 were medically managed.
• 6.7% (3/45) of surgically treated dogs died due to shunt-related complications; 22.2% (4/18) of medically managed dogs died.
• Hypoplastic portal vein was noted in 52.9% of dogs where portal anatomy was described.
• 37.5% of surviving attenuated dogs were weaned off all medical management.
• Attenuated dogs had higher 1-, 2-, and 5-year survival rates (89%, 77%, 77%) than nonattenuated dogs (82%, 49%, 24%).

🔍 Key Findings

• Both patient-specific and universal guides yielded correction errors <2°, with no statistically significant difference in accuracy.
• Universal guide corrected aLDFA up to 24° and AA up to 20°, addressing multiplanar deformities effectively.
• Patient-specific guides allowed for preoperative simulation, providing more stable pin placement and potentially aiding less-experienced surgeons.
• Universal guide eliminated the need for CT-based customization, reducing time and cost.
• Cadaver and bone model trials showed consistent accuracy, validating both methods in vitro and ex vivo.
• No significant differences in outcome when correcting uniplanar (aLDFA) vs biplanar (aLDFA + AA) deformities.
• Universal guide's fixed size presented limitations in small dogs, potentially requiring multiple size options.
• Universal guide showed potential for standard use, offering repeatable outcomes with minimal prep despite needing precise intraoperative placement.

🔍 Key Findings

• WMg (water manometer with gauge) was the most accurate and precise pressure measurement device.
• APT (arterial pressure transducer) was less accurate than WMg but still precise; it differed significantly from the gold standard (WMr).
• CCT (Compass CT) was the least accurate and precise and differed significantly from the set pressure.
• Mean differences from set pressure were smallest for WMg (−0.020 cm H2O), moderate for APT (−0.390 cm H2O), and largest for CCT (−1.267 cm H2O).
• All devices showed excellent interobserver (ICC = 1.000) and intraobserver agreement (ICC range 0.985–0.998).
• Even though the CCT performed least well, all devices had mean errors ≤1.3 cm H2O, indicating potential clinical utility.
• WMg or WMr should be preferred in surgical settings due to superior accuracy and precision.
• Measurement precision is more critical than accuracy during PSS surgery, as a 1 mm Hg (~1.3 cm H2O) increase in portal pressure raises odds of poor outcomes by 9%.

🔍 Key Findings

• Fluoroscopically guided normograde metabone pinning (FGNMP) was used to treat 17 animals (15 dogs and 2 cats) with 57 metabone fractures, including various fracture configurations (short-oblique body, physeal, and comminuted).
• All 57 fractures were stabilized using intramedullary pins via FGNMP. The study exclusively focused on pin fixation and did not include screws or combined fixation techniques.
• Median surgical time was 54 minutes (range 26–99 min), indicating efficient procedural execution.
• Radiographic bone union was achieved in all fractures, with a median time to union of 6 weeks (range 4–12 weeks). Union was confirmed in all initially non-united fractures on follow-up.
• No major complications were reported. A single pressure sore at the olecranon resolved uneventfully, and no pin migration or osteomyelitis was observed.
• Pin extensions were noted radiographically (e.g., 42% distal subchondral overextension), but were not associated with clinical problems.
• Fluoroscopic guidance improved implant accuracy and preserved soft tissue, enabling effective fracture alignment and stabilization using this minimally invasive osteosynthesis (MIO) approach.
• The authors concluded that FGNMP is an effective, safe, and minimally invasive method for a variety of metabone fracture types, yielding quick recovery, fast healing, and good to excellent long-term functional outcomes in all 17 cases.

🔍 Key Findings

• LAER was effective (partial or complete) in 35/40 cases, regardless of FB location or type.
• Intestinal wall damage significantly increased the likelihood of conversion to enterotomy (p = .043).
• LAER led to significantly shorter hospitalization (median 48 h vs 72 h; p = .006).
• Patients in the LAER group required less postoperative analgesia (median 36 h vs 48 h; p < .001).
• Faster return to spontaneous feeding was seen in LAER group (median 24 h vs 36 h; p = .012).
• No significant difference in complication rate or postoperative ileus between LAER and enterotomy groups.
• Sharp, linear, or multiple FBs did not significantly affect LAER effectiveness.
• Conversion to surgery was required in 5/40 LAER attempts, mostly due to immovable FBs or intestinal damage.
