In Song 2024 et al., on CT vs cystoscopy for ectopic ureters in dogs, what did the authors conclude regarding CT's role in surgical planning?
🔍 Key Findings
- CT correctly identified ectopic ureters in 91% of dogs, but missed 50% of normal ureters, limiting its negative predictive value.
- Sensitivity for intramural ectopic ureters was 65%, while specificity was 71%, indicating moderate diagnostic performance.
- Sensitivity for extramural ectopic ureters was only 29%, despite a high specificity of 97%.
- CT was inaccurate in predicting ureteral orifice location, with sensitivity ranging from 0% to 76% depending on the site.
- 26% of dogs were misclassified for cystoscopic laser ablation (CLA) eligibility based on CT findings alone.
- Overall CT accuracy for CLA candidacy was 74%, but a significant minority would have been inappropriately treated.
- Multivariate analysis found no predictive factors (e.g., colon distension, body weight) for when CT would be incorrect.
- Authors recommend confirmatory cystoscopy to verify CT findings prior to treatment planning.

In Ibrahim 2022 et al., on scrotal arterial supply, what was concluded regarding the use of scrotal flaps in neutered dogs?
🔍 Key Findings
- Dorsal scrotal arteries, branching from the ventral perineal arteries, are the dominant arterial supply to the scrotum in dogs.
- The ventral scrotal arteries, arising from the external pudendal arteries, perfused only the cranial scrotal border and were inconsistently present or absent in some dogs.
- A scrotal flap based on the dorsal scrotal arteries showed strong perfusion and may be a viable axial pattern flap.
- Perfusion was consistent across fresh and frozen cadavers, showing no difference due to preservation method.
- Poor flap survival (27%) occurred when based on cranial supply alone (i.e., ventral scrotal arteries), confirming importance of preserving caudal supply.
- There are anastomoses between dorsal and ventral scrotal arteries, offering collateral flow but insufficient alone for complete perfusion.
- Scrotal flaps based on the caudal pedicle may be applicable for reconstruction of proximal medial/lateral thigh wounds.
- Proposed flap requires careful preservation of ventral perineal arteries, ideally designed 2.5–3 cm lateral to midline in large dogs.

In Loh 2024 et al., on treatment outcomes for CvHL in dogs, which nonsurgical method had the highest success rate?
🔍 Key Findings
- Low-trauma events caused 82.9% of CvHL cases; Poodles and poodle-crosses represented 49.4% of cases.
- Success rate of hobbles (61.8%) was significantly higher than closed reduction alone (10.3%) or Ehmer sling (18.5%).
- Multivariate analysis found hobbles 7.62x more likely to succeed vs. closed reduction (p = .001).
- Specialist surgeons had higher success with nonsurgical management (OR: 2.68; p = .047).
- Older age associated with better outcomes (OR: 1.15 per year; p < .0005).
- Ehmer sling is not recommended due to high failure and complication rates (60.6%).
- Toggle rod stabilization had a high surgical success rate (88.2%) with low complication.
- No link was found between CvHL and hip dysplasia or OA in most cases (only 2/108 showed OA).

In Zweig 2025 et al., on healed tibial tuberosity avulsion fractures, what conclusion was reached regarding non-surgical management?
🔍 Key Findings
- Surgically managed TTAF resulted in excellent clinical outcomes at skeletal maturity, with all dogs having normal limb function and no stifle instability.
- Surgical treatment significantly altered proximal tibial morphology, including decreased tibial plateau angle (TPA) and increased patellar position (PP) compared with the contralateral limb.
- Axial tibial tuberosity position (TTP-A) increased and transverse position (TTP-T) decreased in surgically treated stifles, indicating distal and caudal tuberosity migration.
- Non-surgically managed TTAF did not significantly alter tibial morphology or PP, but outcomes were more variable.
- Medial patellar luxation developed in 2/6 non-surgically treated dogs, whereas none occurred in surgically managed cases.
- Pins-only and pin–tension band constructs produced similar radiographic changes and outcomes.
- Despite morphologic changes, no dogs developed cruciate ligament instability at follow-up.
- Non-surgical management yielded good to excellent owner-reported outcomes, but carried a potential increased risk of patellar luxation.

In Cola 2024 et al., on laparotomy-assisted endoscopy, what was the primary factor associated with the need to convert to enterotomy?
🔍 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.

In Lhuillery 2022 et al., on GDV stabilization timing, which preoperative intervention was key to enabling delayed surgery without compromising outcomes?
🔍 Key Findings
- Survival rates did not differ between immediate (90 min) and delayed (≥5 h) surgical stabilization groups at discharge or 1-month post-op (approx. 80% survival in both).
- Hyperlactatemia at 24 hours post-fluid therapy was significantly associated with in-hospital and 1-month mortality (P = .01 and P = .02).
- Persistent tachycardia during hospitalization was linked to increased 1-month mortality (P = .015).
- Partial gastrectomy was required in ~6–10% of cases, with high associated mortality.
- Preoperative stabilization protocols (trocarization, nasogastric tube) allowed safe surgical delays up to 13.7 hours without impacting survival.
- Degree of gastric torsion differed between groups; more 0° torsions in delayed cases, potentially due to decompression-induced derotation.
- No difference in post-op complications such as arrhythmias, hypotension, or AKI between groups.
- More intra-anesthetic deaths occurred in immediate surgery group, highlighting importance of adequate pre-op stabilization.

In Healy 2025 et al., on incidental PBBs, what recommendation is made regarding prophylactic lung resection?
🔍 Key Findings
Population: 2,178 canine CTs reviewed retrospectively.
Prevalence: Incidental PBBs found in 1.37% (30/2178).
Outcome: None of the dogs with incidental PBBs developed clinical spontaneous pneumothorax (SP) over a median follow-up of 1255 days.
Significant Associations:
- Age: Dogs with PBBs were significantly older (median 10.5 yrs vs. 8.2 yrs, p = .001).
- CT indication: PBBs more likely during neoplastic staging (p = .006).
PBB Characteristics:
- Total = 60 PBBs (median 1/dog; range 1–7).
- Location: 35% in left caudal, 31.6% right caudal, only 13.3% in right cranial lobe.
- Size-based: 25 bullae (>10 mm), 35 blebs (≤10 mm).
Conclusion: Prophylactic resection of incidental PBBs not justified given no observed SP risk in this population.

In Miller 2024 et al., on intestinal obstruction and catheter technique in cats, what was the overall success rate of the red rubber catheter technique (RRCT) for removing linear foreign bodies?
🔍 Key Findings
- Cats with linear (LFBO) and discrete (DFBO) small intestinal obstructions had similar survival (98.2% vs. 97%, p = 1.0).
- Postoperative complications were not significantly different between LFBO and DFBO cases (p = .1386).
- Intestinal dehiscence was rare (only 2 cats), both in DFBOs, with no statistical difference between groups.
- Red rubber catheter technique (RRCT) successfully removed LFBOs in 83% (20/24) of attempts.
- All failed RRCTs occurred in cats with perforations or tissue nonviability.
- Cats with failed RRCTs had longer clinical signs pre-surgery (median 6.5 vs. 2.0 days).
- Surgical time was longer in LFBO cats (median 77 min vs. 58 min, p = .0018).
- Preoperative septic peritonitis was rare (4/169 cats), but occurred only in linear or mixed FBO cases.
