Variables were assessed at the stifle flexions of 90° and 135° with both intact cranial cruciate ligament (CCL-In) and after mechanical transection (CCL-MT). Three evaluators measured the distance (d) between the TIcE and needle center. Statistical analysis involved a linear mixed model, with the Bonferroni test (p < .0125).Results: Analyses of CCL-In and CCL-MT groups revealed statistically significant differences between needle positions and stifle flexion angles. In the CCL-In group, the C-90° position was closest to the stifle center (d = 0.45 ± 2.39). For the CCL-MT group, the C-135° position was nearest (d = 0.11 ± 2.18).Conclusion: The center of the MCL in the sagittal plane, at 135° of stifle flexion, served as a reliable anatomical reference for identifying the TIcE in dogs with CCL disease.Clinical significance: A meticulous intraoperative identification of the TIcE can improve the accuracy of tibial osteotomies, potentially optimizing tibial plateau leveling osteotomy outcomes.","PeriodicalId":23667,"journal":{"name":"Veterinary Surgery","volume":" ","pages":"1337-1343"},"PeriodicalIF":1.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144209650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each cadaver was positioned in supported sternal recumbency for all procedures. Ports were placed bilaterally in the dorsal flank. All findings and complications were recorded.Results: All sentinel lymph nodes (SLNs) identified on CTL were identified on laparoscopic SLNM and were amenable to dissection and extirpation.

Placement success was confirmed via thoracoscopy. Success rate, procedure duration, and reasons of failure were recorded.Results: B-Coda catheter placement was possible on dogs intubated with a minimum 8.5 mm size endotracheal tube (ETT). E-EZ was unsuccessful with an 8.5 ETT and below and on some dogs bigger than 30 kg. Excluding the failures due to size limitations of the devices, success rate during first attempt for the left side was 50% for B-EZ and 75% for all other techniques. Right-sided success was 50% for B-EZ, 33% for B-Coda, 66% for E-EZ and 62% for E-Coda. Malpositioning of the devices occurred twice as commonly under borescopic guidance. The techniques were all successful after up to two additional attempts. Time to achieve blockade was faster using endoscopic guidance.Conclusion: The catheter allowed bronchial occlusion in larger canine cadavers. The borescope allowed guidance without the size limitation of the endoscope.Clinical relevance: The Coda catheter had no size limitation in comparison to the EZ blocker and could be analternative to it.

The TPAPOST, tibial long axis shift, change in tibial length and wedge angle were recorded and a linear mixed-effects model was used to compare differences amongst techniques.Results: The median TPAPOST for the CCWOCORA method was 5.00° (range: 5.00-5.00°) across a variety of tibial morphologies, whereas all other methods showed greater variability.

Cameras and monitors are now high-definition or 4 K, increasing the clarity of the image available to the surgeon. Those progresses have made minimally invasive surgery safer. However, the biggest challenge of minimally invasive surgery is the lack of depth perception, which requires the surgeon's brain to recreate a three-dimensional (3D) image using cues in the field. The development of 3D cameras enable surgeons to have a more realistic depth perception. The development of the third generation of 3D cameras, combined with light-polarizing glasses, resolved the problem of dizziness experienced by surgeons during long and complicated procedures.Aims: To review the evidence from human and veterinary surgery regarding the benefits of 3D visualization during laparoscopy.Conclusions and implications: The evidence suggests that 3D visualization enhances depth perception, safety, a smoother learning curve, and overall wellness for surgeons. Some controversies persist on the clinical benefit of 3D visualization, even if most of the studies showed statistically significant reduction of operating time, estimated blood loss, operating errors, and shorten hospital stay in human patients.","PeriodicalId":23667,"journal":{"name":"Veterinary Surgery","volume":" ","pages":"1298-1304"},"PeriodicalIF":1.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144790187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four-point bending tests were performed in flexion (3DM n = 6, LCP n = 6) and extension (3DM n = 6, LCP n = 6) in a single cycle to failure. Yield, failure moment, and stiffness in flexion and extension were compared between the 3DM and LCP groups using a mixed effects linear regression model.
