In Miller 2024 et al., on leak testing in cooled feline intestine, what explanation was given for higher leak pressures compared to canine data?
🔍 Key Findings
- No difference in initial leak pressure (ILP) or maximum intraluminal pressure (MIP) between cooled (17–29 h) and fresh enterotomy constructs.
- Wall thickness of duodenum and jejunum did not differ between fresh and cooled samples.
- Leak locations (suture holes vs clamp sites) were similar between groups; not statistically different.
- Volume of infusion did not influence ILP or MIP outcomes.
- Mean ILP values: Control = 600 mmHg (maxed), Fresh = 200 mmHg, Cooled = 131 mmHg; CE vs FE difference was not significant.
- Intraluminal diameter was largest in the ileum, followed by jejunum and duodenum.
- Cadaveric intestine cooled ≤29h may be reliably used in ex vivo feline leak pressure studies.
- First report of gross small intestinal lengths by region in cats—useful for resection planning.

In Quitzan 2022 et al., on staple line configuration, which FEESA variation did *not* significantly increase ILP compared to 2V/2T?
🔍 Key Findings
- All FEESA configurations leaked at lower pressures than intact segments, confirming reduced integrity vs. native tissue.
- FEESA with 3-row transverse staples (3V/3T or 2V/3T) had significantly higher leak pressures than 2-row configurations.
- 3V/3T configuration had the highest ILP (69.88 ± 21.23 mmHg) among all groups, significantly greater than 2V/2T and 3V/2T (P < .001).
- Leakage consistently occurred at the transverse staple line (not vertical), regardless of configuration.
- No significant difference in maximum intraluminal pressure (MIP) between FEESA groups.
- All FEESA constructs withstood intraluminal pressures >25 mmHg, exceeding normal physiological jejunal pressure in dogs.
- No leaks occurred from the vertical staple line, highlighting it as a more robust closure site.
- Third staple row in transverse line may be a viable alternative to suture oversew, pending further clinical evaluation.

In De Moya 2023 et al., on femoral pinning outcomes, what factor was most commonly associated with good healing outcomes?
🔍 Key Findings
- FGPP (fluoroscopic-guided percutaneous pinning) resulted in successful healing in 10/13 fractures, with good limb function.
- Complications occurred in 5 of 11 cases, including intra-articular implants, malunion, implant failure/nonunion, and implant migration.
- Cases with delayed surgery (>15 days) or radiographic remodeling were more likely to experience major complications.
- Most fractures (10/13) were classified as Salter-Harris type I with mild displacement.
- Median surgical time was 60 minutes, and no conversions to open surgery were needed.
- Postoperative femoral neck resorption was minimal, suggesting possible benefits of the minimally invasive approach for preserving vascular supply.
- One intra-articular pin led to progressive joint disease and required femoral head ostectomy.
- FGPP appears best suited for acute, minimally displaced fractures in young dogs (<8 months) with planned elective explant to avoid growth disturbance.

In Whitney 2022 et al., on CBLO fixation strength, regarding biomechanical testing of CBLO constructs, what was the main mode of failure in constructs using only a plate and pin?
🔍 Key Findings
- CBLO fixation with both a headless compression screw (HCS) and tension band (TB) showed the highest yield and ultimate loads compared to other configurations
- HCSTB constructs had significantly higher yield load (1212 N) and ultimate load (1388 N) than Plate alone (788 N, 774 N), HCS alone (907 N, 927 N), or TB alone (1016 N, 1076 N)
- No difference in construct stiffness was detected among the four fixation methods tested
- All constructs ultimately failed by bone fracture—location of failure differed by construct type (e.g., through HCS hole or cranial screw hole)
- TB and HCSTB groups showed failure via progressive TB stretching and cranial osteotomy widening, while Plate and HCS failed more abruptly
- All constructs withstood forces exceeding expected quadriceps load in vivo (170–325 N), suggesting all methods can resist physiological loading, but HCSTB provides greater safety margin
- HCS alone was not significantly stronger than Plate or TB alone, questioning its standalone superiority
- Study supports using TB and HCS together for optimal construct strength, but clinical studies are needed to validate implant fatigue, healing, and failure rates

In McCagherty 2025 et al., on WID detection accuracy, what was the main type of bacterial population detected in most wound infections?
🔍 Key Findings
- Bacterial fluorescence was detected in all wounds (17 dogs, 4 cats) using the point-of-care wound imaging device (WID).
- The WID confirmed the presence of clinically relevant wound infection in all evaluated cases at the time of imaging.
- No significant difference was found in bacterial yield or burden between image-guided and non-guided swabs (QBC and PCR; p > 0.05).
- The WID helped guide wound debridement in some cases by localizing areas of fluorescence, especially in necrotic tissue.
- Most infections were polymicrobial and dominated by anaerobes, highlighting the need for anaerobic culture inclusion.
- PCR analysis showed low bacterial DNA yields, often complicated by host DNA contamination, limiting its utility.
- The study did not evaluate sensitivity/specificity of WID, as only fluorescence-positive wounds were included.
- Clinical utility of WID lies in immediate visual confirmation of infection, supporting timely antimicrobial treatment decisions.

In Miyagi 2025 et al., on endoscopic laser sphincterotomy, what was the outcome of the two cases with lateral perforation?
🔍 Key Findings
- Endoscopic-assisted retrograde catheterization (EARC) and laser sphincterotomy were successful in 18/18 cadavers, demonstrating technical feasibility.
- Intramural common bile duct (ICBD) length ranged from 10 to 21 mm (mean 15.8 mm), with no correlation to body weight (r = 0.06, p = .79).
- Transition from ICBD to extramural duct was accurately identified endoscopically in 88% (16/18); transition was heralded by separation of the submucosal layer.
- Partial lateral perforations occurred in 2/18 dogs, only during early learning phase; no leakage was found on open dissection.
- Laser sphincterotomy preserved the pancreatic duct orifice, aided by protective catheter positioning.
- Compared to open duodenotomy, this technique allows for a smaller incision and less manipulation of the pancreas, which may reduce morbidity.
- No adverse events such as intra-abdominal saline egress or full-thickness perforation occurred, and the technique allowed safe access up to 10 mm from the MDP.
- Cadaveric limitations included absence of biliary pathology and inability to evaluate live complications, but the technique shows promise for future live animal trials.

In Hernon 2023 et al., on flushing the CBD, which of the following was the most common postoperative complication in dogs undergoing cholecystectomy?
🔍 Key Findings
- Flushing the common bile duct (CBD) during cholecystectomy did not result in improved hepatobiliary markers compared to no flushing.
- Cholecystectomy alone significantly reduced ALP, ALT, GGT, bilirubin, and cholesterol 3 days postoperatively (p < .05 for all).
- Survival to discharge was 90.3%, with no survival difference between flushed and non-flushed groups.
- Postoperative pancreatitis occurred in 12.9% of dogs, evenly distributed between groups, suggesting flushing did not increase risk.
- Most common complication was regurgitation (29%), not significantly different between groups.
- Free abdominal fluid had low sensitivity (29%) but moderate specificity (73%) for gallbladder rupture.
- No difference in duration of hospitalization or postoperative complications between groups.
- Gallbladder rupture rate was 12.9%, lower than previously reported in literature.

In Danielski 2024 et al., on PUO effect on HIF, what was one proposed biomechanical outcome of PUO regarding the anconeal process?
🔍 Key Findings Summary
- Sample: 51 elbows from 35 spaniel dogs
- Healing Rate: Subjective healing (complete or partial) in 80.3% of elbows; complete in 54.9%
- Objective HU analysis: Mean HU increased from 640 (pre-op) to 835 (follow-up) (p = .001)
- Age Effect: Dogs <14 months showed the greatest HU increase (+384 HU) and had wider fissures with less sclerosis
- Complications:
- Major: 5 dogs (6 limbs); 4 related to fissure healing (7.8%), 2 related to PUO healing (3.9%)
- Minor: 3 cases (5.8%) due to IM pin migration
- Sclerosis: Older dogs had more humeral condyle sclerosis, possibly limiting healing
- PUO Effectiveness: Confirmed cranio-proximal displacement of anconeal process; aimed to relieve humero-anconeal incongruity
- Control Comparison: Avoids complications associated with transcondylar screw (infection, breakage)

In Rocheleau 2023 et al., on shoulder stabilization, which complication was more common with bone anchor placement than with suture-toggle stabilization?
🔍 Key Findings
- Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
- Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
- Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
- Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
- Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
- Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
- CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
- Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.

In Duvieusart 2025 et al., on lung lobectomy approaches, what conclusion was drawn about stapler success across techniques?
🔍 Key Findings
- Study Design: Canine cadaveric study comparing intercostal thoracotomy (ICT), median sternotomy (MS), and transdiaphragmatic with caudal median sternotomy (TDCM) for accessory lung lobectomy (ALL).
- Main Outcomes:
- Exposure Area: TDCM (193.5 cm²) > MS (106.5 cm²) > ICT (73.5 cm²) (p = .01).
- TDCM provided significantly greater exposure than MS (p = .02) and ICT (p = .02); MS > ICT (p = .04).
- Surgical Time: No significant difference (p = .06).
- Lobe Excision (% by weight/surface area): No significant difference between groups (p = .4).
- Staple Line Leak: Leak at ≤40 cmH₂O in 2/4 ICT, 0/4 MS, 0/4 TDCM (p = .09).
- Complications:
- 1/4 MS cases had iatrogenic damage to an adjacent lobe.
- Technical Insights:
- TDCM approach allowed immediate visualization of all three parts of the right pulmonary ligament.
- The TDCM approach offers improved access without requiring en bloc removal with the right caudal lobe.
- Conclusion: The TDCM approach provides improved exposure for ALL lobectomy with no increase in surgical time or complications relative to other approaches.
