In Hertel 2025 et al., on portal venotomy for insulinoma, what was the dog's outcome one year postoperatively?
🔍 Key Findings
- Portal venotomy enabled successful en bloc resection of a pancreatic insulinoma and associated thrombus in the portal vein, a novel approach in veterinary literature.
- Temporary portal vein occlusion (15 min) was well tolerated, causing only transient small intestinal congestion without lasting hemodynamic compromise.
- No intraoperative hemorrhage occurred following vascular isolation and venotomy repair with 5–0 polypropylene in a simple continuous pattern.
- Postoperative complications were minimal, with only moderate pancreatitis managed medically and no portal hypertension observed on follow-up imaging.
- Histopathology confirmed insulinoma, with no initial metastasis; CT at 6 months revealed hepatic and peritoneal metastases but no local recurrence at the venotomy site.
- Portal vein luminal stenosis occurred post-repair but was clinically insignificant.
- Advanced CT imaging and 3D printed modeling significantly enhanced surgical planning and anatomical assessment.
- Surgical excision achieved good short-term outcomes, and the dog was alive and euglycemic one year later despite metastatic disease.

In Almeida 2025 et al., on TPLO and partial CCL rupture, what impact did partial CCL rupture have on postoperative patellar ligament shortening?
🔍 Key Findings
- Transecting the CCL remnant during TPLO did not reduce patellar ligament thickening (PLT) at any measured point (proximal, mid, distal).
- Transection also failed to reduce postoperative patellar ligament shortening (PLL) at 6 weeks.
- Both groups (transected vs non-transected) showed significant thickening and shortening, with greatest PLT increase at the midpoint.
- Increased PLT was positively correlated with tibial plateau rotation (p = 0.02) and postoperative TPA (p = 0.04).
- No correlation between TT-O (tibial tuberosity width index) and PLT, suggesting narrow osteotomies did not influence PLT in this population.
- Partial CCL rupture was not significantly protective; dogs with partial tears still developed ligament thickening.
- Post-TPLO mid-patellar ligament thickening may relate to Gelpi retractor placement and osteotomy mechanics rather than CCL status.
- Authors do not recommend CCL transection during TPLO to prevent desmitis, citing possible increased instability and degeneration.

In Dobberstein 2024 et al., on liver biopsy forceps, which biopsy technique showed good diagnostic agreement between 3 mm and 5 mm samples?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Schroeder 2022 et al., on fascial anatomy mapping, what is the characteristic of type I fascia?
🔍 Key Findings
- Fascial planes in dogs were consistently classifiable into four surgical types:
- Type I (discrete sheets), Type II (tightly adhered to thin muscle), Type III (tightly adhered to thick muscle), and Type IV (periosteum-associated).
- Two junction types were identified: Type A (easily elevated) and Type B (higher risk of disruption).
- Disruption-prone areas include the scapular spine (type IV fascia) and lateral thorax near the 13th rib, where rib resection may be needed to preserve margins.
- The latissimus dorsi transition zones and fascial areas near the thoracic inlet and scapulohumeral joint were prone to fascial thinning or disruption.
- Partial muscle resections or periosteal elevations may be required in areas with fragile fascia to maintain oncologic margins.
- Dorsal spinous processes (T6–L6) showed type IV fascia; however, osteotomy may be needed in some dogs for clear margins.
- Blended fascial transitions (e.g., rectus abdominis: type II cranially, type I caudally) necessitate intraoperative judgment on resection depth.
- Cutaneous trunci may suffice as a deep margin for small, low-grade tumors in well-muscled dogs, but not reliably for high-grade or larger masses.

In Mayhew 2023 et al., on BOAS surgery effects, what was the impact of CMS on videofluoroscopic signs of hiatal herniation and gastroesophageal reflux?
🔍 Key Findings
- Owner-reported regurgitation improved after CMS, especially post-eating and during activity (P = .012 and P = .002)
- No significant improvement in VFSS measures of SHH or GER postoperatively (P > .05 for all comparisons)
- Laryngeal ventriculectomy and soft palate resection were performed in all dogs, alaplasty in 14/16
- Aspiration pneumonia occurred in 1 dog immediately post-op and resolved with treatment
- Post-op esophagoscopy results varied, with persistent esophagitis in some cases
- Clinical response was variable, with ~25–30% of dogs being “non-responders” based on owner scoring
- 13/16 dogs showed partial or full clinical improvement, despite no change in objective SHH/GER indicators
- Final follow-up at median 36.5 months showed some dogs still on medical therapy; one underwent further surgery

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 Becker 2026 et al., on lumbar spine PLC biomechanics, how did the second PLC compare biomechanically to the first in terms of passive range of motion increase?
🔍 Key Findings
- Each PLC significantly increased passive range of motion (ROM) in the sagittal and dorsal planes (p < .05).
- No significant change was observed in rotational ROM after either PLC.
- First PLC increased sagittal ROM by 2.4° (23% increase); second PLC added 1.0° (8% increase).
- Dorsal ROM increased by 2.3° after first PLC and 1.5° after second PLC.
- Second PLC did not cause greater destabilization than the first — both contributed similarly to ROM increase.
- Failure testing showed that spinal segments with two PLCs failed at 13 Nm, while native spines withstood up to 25 Nm, suggesting reduced load-bearing capacity but not clinically significant under normal conditions.
- Rotational stability was preserved, possibly due to intact facet joints and lamina, which play a larger role in rotation.
- Study supports the clinical feasibility of two consecutive PLCs, but cautions against excessive bone removal due to potential for spinal instability.

In İnal 2025 et al., on supracutaneous locking plates, which screw configuration was consistently used for adequate stability?
🔍 Key Findings
- Supracutaneous locking plates (SLPs) were successfully used to manage 33 diaphyseal fractures (radial–ulnar and tibial) in 30 cats and dogs.
- Median fracture healing time was 50.5 days (range: 27–88), with most patients regaining limb use within days postoperatively.
- CT-based metrics (callus area, HU, and 3D bone volume) increased significantly during healing (p < 0.05), validating CT as a quantitative tool for assessing healing.
- Complications were minimal: minor in 15/33 (e.g., screw tract discharge, edema), and major in 3/33 (e.g., implant failure, delayed union, nonunion).
- Minimally invasive osteosynthesis required longer surgery times than closed reduction (p < 0.05), but both techniques were viable.
- SLPs enabled successful bilateral fracture management without inter-plate interference due to their compact design.
- Screw orientation challenges were noted in cats, especially with cranial application to the radius due to narrow anatomy.
- Polyaxial locking screws were used safely and did not dislodge, allowing for angular insertion (≤10°) to avoid neurovascular structures.

In Cruciani 2022 et al., on feline pancreaticoduodenostomy, what was the final histopathologic diagnosis following euthanasia?
🔍 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.
