In Chik 2025 et al., on abdominal wall prestretching, what was the observed effect on working space when PS was applied at 10 mmHg for 3 minutes and then reduced to 6 mmHg IAP?
🔍 Key Findings
- Prestretching (PS) at 10 mmHg for 3 minutes significantly increased working space at 6 mmHg IAP — IWL +4.4%, IWS +6.9%.
- PS provided ≈63% of the IWL and ≈66% of the IWS gains achieved with sustained 10 mmHg IAP.
- All laparoscopic procedures were completed at 6 mmHg after PS; no conversions or pressure increases were needed.
- Working space benefits persisted throughout surgery — end-of-procedure measurements were unchanged from post-PS baseline.
- Transverse expansion (RLAT/LLAT) was greater than sagittal (CRA/CAU), consistent with adult abdominal wall compliance.
- No adverse anesthetic events occurred; mild complications (e.g., gas leakage) were easily managed.
- Large breed dogs were overrepresented, but all dogs served as their own controls, normalizing size effects.
- Prestretching is a simple, effective technique to maximize working space without increasing insufflation pressure.

In Moreira 2024 et al., on predictive equations for TPA correction, which technique demonstrated the **highest TLA shift** after cranial cortical alignment?
🔍 Key Findings
- A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
- All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
- TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
- Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
- The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
- Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
- The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
- The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.

In Banks 2023 et al., on TECA-LBO in brachycephalic dogs, which neurologic sign was most significantly more common in extreme brachycephalic breeds (EBBs) preoperatively?
🔍 Key Findings
- Extreme brachycephalic breeds (EBBs) presented more acutely and at younger ages, most often with neurological signs compared to other breeds.
- Preoperative signs such as facial nerve paresis, vestibular syndrome, and Horner’s syndrome were significantly more common in EBBs.
- EBBs showed more severe imaging findings, including higher rates of otitis interna (46.3% vs. 8.5%) and brainstem changes (17.5% vs. 3%).
- Intraoperative complications were more frequent in EBBs (11.1% vs. 5.3%), but this difference did not reach statistical significance (p = .078).
- Perioperative complication rates did not differ significantly between EBBs and other breeds (23.5% vs. 29.3%).
- Surgical time was significantly longer in EBBs (median 115 vs. 95 minutes; p = .011).
- MRI or combined CT/MRI were more frequently used in EBBs, likely due to the higher prevalence of neurological signs.
- Despite anatomical challenges, complication rates in EBBs were comparable, supporting TECA-LBO safety in these breeds.

In Aertsens 2025 et al., on thoracic lift technique, which device was used to create the chest wall lift in the second cat?
🔍 Key Findings
Case 1: Chest wall lift improved oxygenation (PaO₂ increased from 179.4 to 306.3 mmHg) and enabled thoracoscopic-assisted lobectomy in a cat with pleural effusion and pulmonary carcinoma.
Case 2: Chest wall lift using a Steinmann pin allowed 3-port thoracoscopic lobectomy for a bronchial foreign body; no complications observed.
Both cats: Lift increased working space and eliminated need for thoracotomy; no device-related complications.
Pretied ligating loops (PLL) were effective for hilar vessel ligation—preferred over staplers or self-locking ligatures in feline thorax.
Conclusion: Thoracic lift is a novel, minimally invasive method enhancing thoracoscopic procedures in small patients, particularly cats.

In Chan 2025 et al., on partial cuneiformectomy in BOAS dogs, what was the effect of cuneiformectomy on postoperative complication rates compared to multilevel airway surgery alone?
🔍 Key Findings
- Partial cuneiformectomy (PC) did not increase complication rates compared to multilevel surgery alone (overall complications: PC = 16.3%, non-PC = 19.4%; p = .758).
- Major complication rates were not significantly different (PC = 11.6%, non-PC = 7.4%; p = .482).
- Significant improvement in BOAS grade was observed in dogs undergoing PC (p < .0001).
- BOAS index improved significantly in both groups, with greater median reduction in the PC group (28.5%) than non-PC (20.7%) (p < .0001).
- Low body condition score (BCS <4) was significantly associated with higher complication rates (odds ratio = 0.452; p = .004).
- Hospitalization duration did not differ between groups (median = 1 day; p = .743).
- Mortality was low (3.5%) in the PC group despite more severe airway disease, suggesting the technique is safe even in advanced collapse.
- The technique widened the rima glottidis without damaging surrounding structures, reducing airflow resistance and preserving laryngeal function.

In Espinel Rupérez 2023 et al., in Arthroscopic-assisted hip toggle stabilization in cats, what was the median total surgical time for AA-HTS?
🔍 Key Findings
- 14 joints from 7 cat cadavers underwent AA-HTS successfully.
- Median surgical time: 46.5 min (29–144), including 7 min for arthroscopy and 40 min for toggle placement.
- Intraoperative complications in 5/14 joints: 4 related to femoral tunnel creation, 1 toggle lodging.
- Toggle passage through femoral tunnel was the most challenging step, mildly difficult in 6 joints.
- Cartilage injury occurred in 10 joints, but all were minor (<10% of cartilage area).
- 13 deviations from planned technique were identified (8 major, 5 minor), all involving femoral tunnel placement.
- No neurovascular, intrapelvic, or major periarticular injuries occurred.
- Authors conclude: AA-HTS is feasible in cats, but associated with high rates of minor iatrogenic cartilage damage, intra-op complications, and technique deviations.

In Evers 2023 et al., on needle arthroscopy, what was the average time for needle arthroscopy compared to standard arthroscopy?
🔍 Key Findings
- Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for detecting medial meniscal tears using standard arthroscopy (SA) as the reference.
- NA correctly identified meniscal status in 25/26 dogs, missing only one stable nondisplaced tear.
- NA took less time than SA: 8 ± 3 min vs. 15 ± 9 min (P = .0041).
- Visibility scores were significantly lower with NA than SA for all meniscal horns (medial and lateral) .
- Probing difficulty was greater with NA, especially for the lateral meniscus (P = .0017).
- NA caused no measurable morbidity: lameness scores were unchanged before and after the procedure (P = .25).
- NA was possible in sedated dogs, though 10/26 required additional anesthesia due to delays.
- NA missed 1 lateral tear, likely due to reduced access and lack of shaving compared to SA.

In Tobias 2022 et al., on perineal hernia repair positioning, which surgical advantage did dorsal recumbency provide?
🔍 Key Findings
- Perineal hernia repair was feasible in dorsal recumbency in all 23 dogs, allowing simultaneous perineal and abdominal procedures without repositioning.
- Internal obturator muscle transposition (IOMT) was successfully performed in 22 dogs, with tendon transection facilitating improved muscle elevation.
- Complication rate was 60.9% in-hospital and 47.8% post-discharge, mostly minor (e.g., swelling, drainage), with infection suspected in 4 dogs (17.4%).
- Recurrence rate was 19% overall, but significantly higher in dogs with prior hernia repairs (50% vs 5.9%; p = 0.053).
- Dogs without prior repairs or organ pexies had no recurrences (p = 0.035), suggesting primary repairs without preexisting interventions fare better.
- Castration and adjunctive abdominal procedures (e.g., colopexy, cystopexy) were often performed concurrently (18/23 dogs).
- Colopexy did not prevent recurrence, although it aided in surgical visualization during perineal repair.
- Dorsal positioning allowed simultaneous access to the abdomen and perineum, improving surgical efficiency without added complications.
