🔍 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.

🔍 Key Findings

• TPLO with the contoured saw guide achieved more accurate osteotomy angles for both inclination and torsion in bone models and cadaveric limbs (p < .05).
• Medial cortical damage was significantly lower with the contoured guide (247 vs. 1866 pixels in bone models; p < .001).
• No significant difference in eccentricity (distance between actual and intended osteotomy center) was found between groups.
• Postoperative tibial plateau angle (TPA) was similar between groups (6.4° vs. 7.6°; p = .15), though both were slightly higher than the target of 6°.
• Deviation in medial mechanical proximal tibial angle (mMPTA) showed no significant group difference; valgus deformity occurred in both.
• Osteotomy and device application times were similar between the contoured guide and jig-assisted TPLO.
• The contoured guide eliminated the need for proximal jig pin, potentially reducing intra-articular pin risk.
• The guide's multiple pin fixation system improved stability and alignment, supporting safer osteotomy on curved tibial surfaces.

🔍 Key Findings

• Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
• PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
• No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
• No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
• Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
• SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
• Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
• No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.

🔍 Key Findings

• Laparoscopic cholecystectomy (LC) was successfully performed in all 22 cats without conversion to open surgery.
• Complication rate was low: 3 cats had postoperative complications (1 seroma, 1 vomiting, 1 EHBDO and death).
• Median operating time was 41 minutes; median hospitalization was 3 days.
• No cases required conversion to open laparotomy, even in cats as small as 2.5 kg.
• Common devices used: Hemoclips or Hem-o-lok for cystic duct ligation; Ligasure, harmonic scalpel, or j-hook for dissection.
• Most common indications: cholelithiasis (9/22) and cholecystitis (10/22), with one biliary mucocele and one adenoma.
• Histopathology confirmed diagnosis in all cases; concurrent liver or intestinal biopsies were performed in some cats.
• Postoperative AUS and bloodwork were routine and important for detecting early signs of EHBDO.

🔍 Key Findings

Sample: 201 lymphadenectomies in 163 dogs.
Intraoperative techniques:

• Unassisted: 36%
• Methylene blue (MB): 24%
• Gamma probe + MB (γ-MB): 40%

Complication rate: 7.5% overall (93% uncomplicated)

• 80% were mild, 20% moderate; no severe complications
• Most common = seroma (2.5%), lymphoedema (1.5%)

Risk factors (via decision tree model):

• Surgical time > 21.5 min
• Lymph node site = mandibular or retropharyngeal

No significant difference in complication rate based on:

• Guidance technique (p = .255)
• LN palpability, number removed, or LN size

Clinical implication: Peripheral SLN excision is safe regardless of intraoperative technique; certain sites and durations carry slightly higher risk.

🔍 Key Findings

• Liver lobectomy was the most common treatment (27/36 dogs), with multiple lobes removed in ~1/3 of cases.
• Septic peritonitis was present in 21/23 sampled dogs, making it a frequent complication.
• Perioperative complications occurred in 21/36 dogs, including aspiration pneumonia, pancreatitis, and acute kidney injury.
• Intraoperative hypotension was common (32/36), often requiring vasopressors or colloids.
• Mortality prior to discharge was 21% (8/38), with deaths related to sepsis, aspiration pneumonia, and multi-organ dysfunction.
• Median survival time was 638 days in dogs surviving to discharge.
• No recurrence of hepatic abscessation was observed in the surviving population.
• E. coli and Clostridium spp. were the most commonly cultured organisms, often as single-agent infections.

🔍 Key Findings

Incidence of BFX lateral bolt stem breakage: 2.95% (13 dogs, 14 stems)

Implant factors:

• 13/14 were BFX lateral bolt stems (sizes #5–7)
• +9 necks used in 5/11 of 17 mm heads
• 10/14 stems undersized based on radiographs
• 10/13 dogs exceeded weight limits for implanted stem size

Malalignment:

• 10/14 had varus alignment (median 3.9°)
• 8/14 had insufficient proximodistal seating

Breakage site: Proximolateral shoulder in all cases

Revision outcomes:

• 11 revised (7 CFX, 3 larger BFX, 1 collared)
• 9/10 revised dogs regained full function
• Complications: 1 rebreakage, 1 periprosthetic fracture, 1 fixation failure

Histopathology:

• Electron microscopy showed fatigue striations and incomplete bead fusion

Conclusion: Avoid small BFX lateral bolt stems if undersized or if long necks required; use weight guidelines to prevent fatigue failure.

🔍 Key Findings

• Bone-to-tendon plate fixation allowed successful stabilization of a highly comminuted calcaneus fracture in a dog with fragments too small for traditional fixation.
• The plate was sutured to the common calcaneal tendon using a figure-of-8 pattern, bypassing the need for screw fixation into small proximal fragments.
• Radiographic union was achieved by 17 weeks, though considered delayed, with the dog returning to normal function by 36 weeks post-op.
• A second surgery was required to replace the tendon-anchored plate with a calcaneus-only plate due to skin ulceration and implant prominence.
• Implant-associated infection was suspected; cultures confirmed Staphylococcus pseudintermedius, managed with doxycycline and clindamycin.
• Use of human placental matrix (hPM) and both autogenous and allogenic bone grafts supported healing, though their specific contribution remains uncertain.
• Postoperative complications included delayed union and skin ulceration, emphasizing challenges of implant design and soft tissue management.
• This is the first report of using a bone-to-tendon plate for a calcaneus fracture in dogs and demonstrates its potential in cases where traditional methods are not viable.

🔍 Key Findings

From “Long-term follow up of 44 cats undergoing total hip replacement” by Rodiño Tilve et al.

• Slipped capital femoral epiphysis (SCFE) was the most common surgical indication (61%, 34/56 hips), primarily affecting young neutered male cats.
• All THRs used cemented micro/nano BioMedtrix implants; most common femoral stem was size #3, and most common acetabular cup was 12 mm.
• Postoperative complication rate was 19.6% (11/56) with 9 major complications (luxation most common), and no intraoperative complications reported.
• All luxations occurred in hips implanted with femoral neck +0 mm length implants.
• Second luxations were more common when revision used same implant size; use of larger implants reduced reluxation rates.
• FMPI-sf score improved significantly from median 2.111 pre-op to 0.111 post-op (P < .001), indicating reduced pain and improved function.
• Very high owner satisfaction: 91% (30/33) reported outcome as "very good."
• No significant associations found between complications and variables like weight, sex, implant size, or surgical indication.

🔍 Key Findings

• Dogs with W-shaped tracheal collapse (WTC) had significantly more stridor and labored breathing preoperatively than those with traditional collapse (TTC) (p < .0001 and p = .0419).
• WTC dogs were 12.1× more likely to require preoperative oxygen support than TTC dogs.
• All dogs (TTC and WTC) survived to discharge after CETP placement; no intraoperative deaths occurred.
• Postoperative laryngeal paralysis occurred in 5 dogs (7.2%), with similar rates between TTC and WTC groups.
• Recurrent tracheal collapse occurred in 3 dogs (1 TTC, 2 WTC), all requiring additional stenting.
• 36-month survival was 75.7% (TTC) and 90.9% (WTC), not statistically different.
• Multivariate analysis showed Yorkshire Terriers (HR = 19.3) and older age (HR = 1.35 per year) were significantly associated with reduced survival.
• CETP was safe and effective for WTC, despite more severe preoperative signs, offering a viable alternative to stenting.
