In Devriendt 2022 et al., on EHPSS blood testing, which **combination** of tests yielded 100% sensitivity for confirming shunt closure?
🔍 Key Findings
- Fasting ammonia (FA) was the most specific test (100%) for confirming EHPSS closure postoperatively.
- Serum hyaluronic acid (SHA) and MEGX at 15 minutes post-lidocaine were the most sensitive tests (96.9% and 96.2%, respectively).
- SHA combined with MEGX T15, or with FA or postprandial serum bile acids (SBA), provided 100% sensitivity with good specificity (72.4–82.8%).
- SHA levels remained elevated in all dogs with persistent shunting, even when other tests were normal.
- Paired SBA had moderate sensitivity (90%) and variable specificity (89%).
- The L/MEGX test at 30 min was less useful than at 15 min for assessing closure.
- Traditional SBA testing showed reduced utility postoperatively; normal values did not rule out persistent shunting.
- Blood tests improved when combined, but imaging remains essential to definitively confirm EHPSS closure.

In Viitanen 2023 et al., on zygomatic sialoadenectomy, which approach required zygomatic arch osteotomy?
🔍 Key Findings
- Intraoral approach (IOA) reduced surgical time compared to lateral orbitotomy (median: 42.0 vs 65.7 minutes, p = .005)
- Ease of closure (Stage III) was better with IOA (p < .001), though gland removal (Stage II) was easier with LOA (p = .039)
- Complete gland removal was achieved in 8/10 IOA vs 10/10 LOA cases in cadaveric study
- All 3 clinical cases had uneventful recoveries post-IOA, including one carcinoma, with no intra- or short-term postoperative complications
- LOA had superior surgical exposure, but was more invasive and time-consuming
- IOA posed greater difficulty in complete gland removal in brachycephalic dogs, with remnant tissue noted in 2/10 cadavers
- IOA avoids osteotomy, reducing potential complications like delayed union and postoperative pain
- Cosmetic outcomes and healing were better with IOA, and no E-collar was required postoperatively

In Pfeil 2024 et al., on fluoroscopic pinning, how many metabone fractures were treated across all animals?
🔍 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.

In Scheuermann 2024 et al., on 3D-printed reduction systems, what percentage of dogs in the 3D-MIPO group had near-anatomic or acceptable fracture reductions?
🔍 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 García 2025 et al., on TIAS shunt confirmation, what confirmed complete shunt occlusion?
🔍 Key Findings
- 40 dogs with congenital EHPSS were surgically treated using intraoperative transsplenic injection of agitated saline (TIAS) to assess full temporary occlusion.
- TIAS was successful in 38/40 dogs; the remaining 2 had additional shunting vessels not originally seen and required further identification/ligation.
- No intraoperative or postoperative complications occurred.
- TIAS allowed real-time confirmation of attenuation success using ultrasound-visible microbubbles.
- Median postoperative bile acids were 5 μmol/L (preprandial) and 25 μmol/L (postprandial).
- Long-term outcomes: 29/39 dogs had excellent, 10/39 had good outcomes; 3 dogs died unrelated to EHPSS.
- Technique is presented as a safe, quick, low-cost, accessible intraoperative assessment alternative to IOMP or SP.

In Thompson 2024 et al., on cyanoacrylate enterotomy sealants, which group had the highest initial leak pressure (ILP)?
🔍 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 Mullen 2023 et al., on microvascular perfusion, which metric differed significantly between obstructed and healthy intestines?
🔍 Key Findings
- Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
- PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
- No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
- No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
- Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
- SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
- Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
- No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.

In Ritson 2025 et al., on feline hilar lobectomy sealants, how were devices evaluated for seal integrity?
🔍 Key Findings
- No leakage occurred using pretied ligature loops (PLL) or double-shank (DS) titanium clips up to 40 cm H₂O airway pressure.
- 1/10 stapled lobes leaked at supraphysiologic pressure (40 cm H₂O), but this was not statistically significant (p = .33).
- All techniques sealed effectively under physiologic and supraphysiologic pressures in cadaveric feline lungs.
- PLL and DS clips required less working space than staplers, making them more practical for small thoracic cavities.
- DS titanium clips offer enhanced security due to dual shanks and tissue-gripping design, reducing clip slippage.
- Leak testing was cyclic and submerged, simulating physiologic ventilation and allowing robust evaluation.
- Stapling failure occurred along the staple line, highlighting risks of air leakage due to staple misalignment or poor hilar access.
- PLL and DS clips may be cost-effective and efficient alternatives for open or minimally invasive feline lung lobectomy.

In Miller 2025 et al., on spinal drill guide accuracy, what was the reported mean deviation between planned and actual screw entry/exit points?
🔍 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.
