🔍 Key Findings

50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):

• Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
• Grade 2 (medical treatment needed): 2/43 (5%)
• Grade 3B (revision surgery): 2/43 (5%)

93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.

🔍 Key Findings

• This study evaluated whether high-fidelity surgical simulator training improved live animal and student outcomes in a feline OHE teaching lab involving 186 cats and 146 students.
• Simulator training significantly improved surgical performance and outcomes:
  • Live surgery was 6 minutes shorter on average in the SIM group vs. NO-SIM (115 ± 21 min vs. 121 ± 16 min, p = .04).
  • Pain scores ≥5/20 occurred in 1% of SIM group cats vs. 15% of NO-SIM group cats (p < .01).
  • Rescue analgesia was needed less frequently in the SIM group (5% vs. 15%, p = .03).
  • Student confidence was significantly higher in the SIM group (median 7/10 vs. 6/10, p < .01).
• The simulator used a realistic abdominal model with friable tissues and required performance of a full OHE procedure.
• The study design was nonrandomized, grouped by class year, with limitations including lack of blinding during pain assessment in year two.
• Authors concluded that pre-lab simulator competency improves both animal welfare and student confidence, recommending it as a prerequisite for live surgical training.

🔍 Key Findings Summary

• Retrospective study of 33 fractures in 31 cats with Salter–Harris I or II distal femoral fractures
• Used 1 intramedullary Steinmann pin + 1 laterally placed antirotational pin
• 96.9% achieved full functional outcome at mid-term follow-up
• No implant migration or removal required
• Minor complications: 2 seromas; Major: 3 (patellar luxation [2], osteomyelitis [1])
• Growth plate remained open in 27.3% of cases at 6–8 weeks post-op

🔍 Key Findings

• Superior and inferior labial arteries in cats perfuse robust angiosomes, which support musculomucosal axial pattern flaps.
• Cadaver angiography confirmed vascular anatomy, with consistent patterns between sides and among specimens.
• The vascular supply is located primarily in the musculomucosal layer, not the skin, critical for flap viability.
• Flap harvest requires inclusion of the orbicularis oris (± buccinator) muscle to ensure vascular integrity and flap survival.
• Two clinical cases demonstrated successful use of superior and inferior labial musculomucosal flaps for palatal reconstruction with complete flap survival and resolution of clinical signs.
• Intraoperative transillumination aided vessel localization, facilitating surgical planning and flap design.
• No cases of distal flap necrosis or dehiscence occurred, although mild donor site morbidity (lip retraction, mucosal denuding) was noted.
• These flaps offer a valuable option when local tissues are compromised, especially after failed previous repairs or radiation therapy.

🔍 Key Findings

• LVSG was successfully performed in 9/10 cadavers and both live cats, demonstrating procedural feasibility.
• Mean stomach resected was 27.6% of total weight in cadavers, with no leaks in 8/8 tested or either live patient.
• Mean surgical time: 110.4 min (cadavers) and 115 min (live cats); no intra- or postoperative complications observed.
• Stenosis near the incisura occurred in 2 cadavers; attributed to staple placement too close to the lesser curvature.
• 3D printed cannulas (3DPCs) improved ergonomics and were used in 6/10 cadavers and both live procedures.
• Live cats lost 21–24% body weight over 3 months, with full return to pre-surgical BCS and no GI complications.
• Orogastric tube and proper tensioning were critical in preventing gastric stenosis during staple placement.
• No reinforcement or oversew was used on the staple line; TriStaple cartridges provided reliable closure.

🔍 Key Findings

• Total complication rate was 16.7%, with 5/30 hips experiencing major complications, mostly related to the femoral component.
• Cup-associated complications were rare (3.3%), with only one case of acetabular cup luxation attributed to surgical technique rather than implant failure.
• No cases of late aseptic loosening were observed during a median follow-up of 17.5 months.
• Implant stability was attributed to the SCSL's porous, trabecular titanium surface, enhancing osseointegration.
• Three femoral stem fractures occurred in a single dog, leading to implant removal; material testing was not performed.
• Most complications were femoral in origin (6/7), not acetabular, suggesting improved performance of the SCSL.
• Explantation rate was 13% (4/30), but some removals were due to owner preference against revision.
• Subjective functional outcome was full recovery in 26/30 hips, including one with successful revision of stem subsidence.

🔍 Key Findings

• All dogs developed progressive osteoarthritis (OA) after surgical debridement of proximal humeral OC.
• Ipsilateral muscle atrophy and reduced shoulder range of motion were common, particularly in unilaterally affected dogs.
• Arthroscopically, lesions showed incomplete cartilage infilling even years after surgery, averaging only ~37% infilling.
• Synovitis was present in all joints, with moderate-to-severe hypertrophy and vascularity scores.
• CT identified OC lesions as deeper and wider than radiography, and all affected joints had more advanced OA than contralateral limbs (P = .001 radiograph, P = .005 CT).
• Kinetic gait analysis showed no significant differences in peak vertical force or impulse, but a subtle 4.4% asymmetric load reduction on the operated limb.
• Median LOAD score was 6, indicating mild owner-perceived disability despite measurable clinical and imaging abnormalities.
• Cartilage infilling was incomplete in all cases, with no lesion exceeding 60% restoration, raising questions about the healing potential of debridement alone.

🔍 Key Findings Summary

• 3 dogs developed permanent fibular nerve dysfunction following TPLO
• Common findings:
  • Drill hole or screw in caudal tibial cortex just distal to osteotomy
  • Caudal malpositioning of TPLO plate (esp. right limb of case 3)
  • Post-op signs: cranial tibial atrophy, knuckling, exaggerated gait, no hock flexion
• One case had confirmed deep/superficial fibular neuropathy via electrodiagnostics
• Recommended prevention: avoid overly caudal drill paths; careful gait assessment at follow-up is key

🔍 Key Findings

80 toy breed dogs with surgically repaired transverse radius/ulna fractures were analyzed.
Fracture gap in the caudal cortex was present in 46% of cases.
Implant failure rate:

• 27% in cases with fracture gap
• 2% in cases without fracture gap

Fracture gap significantly associated with implant failure:

• OR = 23.0, 95% CI: 2.7–197.9, p = 0.004

Absence of external coaptation also associated with increased implant failure risk:

• OR = 10.1, 95% CI: 1.1–89.6, p = 0.04

Prolonged external coaptation (>1 week) linked to non-implant complications (skin wounds, osteopenia, osteomyelitis):

• OR = 5.4, p = 0.04

Plate thickness, type, open screw holes, and working length were not statistically significant predictors of implant failure after multivariable analysis.
