In Israel 2022 et al., on cerclage wire in THR, which of the following statements about cerclage wire outcomes is CORRECT?
🔍 Key Findings
- No proximal femoral fractures occurred in any of the 184 hips with cerclage wire placement
- Cerclage wire was well tolerated, with no failures or complications related to the wire
- Application of a single cerclage wire took <10 minutes, was cost-effective, and required minimal instrumentation
- 3 postoperative complications (1 fissure, 2 fractures) occurred distal to the cerclage site, near the stem tip, requiring plate/screw fixation
- All dogs returned to normal activity, and all owners were satisfied with the outcome
- Cerclage placement location is critical—must be proximal to the lesser trochanter and close to the calcar to resist hoop strain
- Biomechanical evidence supports that cerclage wires improve resistance to hoop strain and subsidence of cementless stems
- Press-fit cementless stems may settle, but when supported by cerclage, this does not result in fractures even in undersized implants

In Devriendt 2022 et al., on EHPSS blood testing, which single test had the highest **specificity** for confirming shunt closure after surgery?
🔍 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 O'Marra 2026 et al., on perioperative septic peritonitis, which of the following is a recommended strategy to mitigate intra-abdominal hypertension in at-risk veterinary patients?
🔍 Key Findings
- Early enteral nutrition (<24–48 hrs) is associated with improved survival and reduced hospitalization in dogs with septic peritonitis.
- Appropriate empirical antimicrobials improve survival in cats, but data are mixed in dogs.
- Recurrent septic peritonitis (RecSP) has poor survival (0%–43.9%); most common cause is gastrointestinal dehiscence.
- Intraoperative hypotension and preoperative hypoalbuminemia may increase dehiscence risk, though findings are inconsistent.
- Lidocaine CRI during surgery improves survival over opioids alone in dogs.
- Hydroxyethyl starch (HES) is not recommended due to risks of coagulopathy and kidney injury; albumin use is controversial.
- Intra-abdominal hypertension (IAH) is under-recognized but contributes to mortality; IAP monitoring should be considered.
- Diagnostic tests (effusion lactate, glucose, cytology) are unreliable for detecting RecSP; clinical judgment and ultrasound are advised.

In Hertel 2025 et al., on portal venotomy for insulinoma, what was the primary reason the authors selected portal venotomy instead of en bloc vessel resection?
🔍 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 You 2025 et al., on barbed sutures for lung lobectomy, what was the observed leakage rate at physiological airway pressure (<20 cmH₂O)?
🔍 Key Findings
- Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
- No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
- Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
- Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
- Staplers remained fastest, with mean ligation time of 2.4 minutes.
- No knot failure or suture breakage was observed in barbed or traditional suture groups.
- Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
- Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

In Gleason 2023 et al., on ala vestibuloplasty in cats, which of the following complications was reported after ala vestibuloplasty?
🔍 Key Findings
- Ala vestibuloplasty significantly reduced normalized pulmonary transit time (nPTT) (mean 5.43 → 3.89 sec; p <.001), suggesting improved cardiopulmonary function.
- Clinical respiratory signs improved, including reduced snoring, sneezing, nasal discharge, and open-mouth breathing (all p <.01).
- Activity tolerance increased, with less dyspnea during activity and longer time to onset of dyspnea (p <.005).
- Paradoxical sternal motion resolved in all affected cats after surgery.
- Hiatal hernias resolved in 75% of affected cats on follow-up CT.
- No serious complications occurred, with only mild, self-limiting epistaxis and hypersalivation in a few cases.
- Aberrant turbinates were detected on CT in all cats, though only 1 showed obstructive CATs endoscopically.
- Total clinical severity scores improved significantly postoperatively (median reduction of 30 points; p <.001).

In Downey 2023 et al., on thoracoscopic lobectomy, what factor was associated with conversion to open thoracotomy?
🔍 Key Findings
- Thoracoscopic (TL) or thoracoscopic-assisted (TAL) lobectomy was successfully performed in 12 dogs with non-neoplastic pulmonary consolidation (PC).
- 44% (4/9) of TL cases were converted to open thoracotomy due to adhesions or poor visualization—higher than rates for neoplastic lobectomies.
- OLV was successful in 7/9 TL dogs; unsuccessful attempts were managed with intermittent ventilation, mostly in brachycephalic breeds.
- Median hospital stay was 3 days; 91.7% (11/12) survived to discharge, and 100% of survivors showed no recurrence at median 24-month follow-up.
- Complications were mostly minor: pneumothorax (2), minor hemorrhage (3), dehiscence (1), and 1 fatality due to BOAS complications.
- Histopathology showed infectious pneumonia in 10 dogs, and in 4 cases, foreign body migration was suspected as the underlying cause.
- Median surgical time for TL was 90 minutes; conversion correlated with longer symptom duration (median 90 vs. 7 days).
- Postoperative recovery was excellent in all surviving dogs, with one case of persistent cough attributed to concurrent heart disease.
