In Hoenecke 2025 et al., on radiographic opacity in patella luxation, what percentage of stifles in dogs with intact CCLs showed increased soft tissue opacity on radiographs?
🔍 Key Findings
- 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
- Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
- Each 1 kg increase in weight increased the odds of opacity by 10%
- Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
- 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
- Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
- Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
- Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

In Poggi 2024 et al., on laparoscopic resection of pancreatic masses in dogs, what was the most common histopathologic diagnosis among the pancreatic masses resected laparoscopically?
🔍 Key Findings
- Laparoscopic pancreatic mass resection (LPMR) was successfully performed in all 12 dogs, with no conversion to open laparotomy required.
- Median operative time was 69 minutes (range 35–100 min); 11/12 dogs were discharged within 48 hours, and one was discharged after 7 days.
- No major intraoperative complications occurred; minor complications included mild bleeding (2/12) and cannula malfunction (1/12).
- All dogs survived the procedure and were discharged.
- Histopathology confirmed neoplasia in all dogs: 9 insulinomas and 3 pancreatic carcinomas; all tumors were completely excised with clear margins.
- No recurrences were reported; 3 dogs died of unrelated causes, and 9 were still alive at the time of reporting.
- No postoperative hypoglycemia was observed; 1 dog had transient hyperglycemia, and minor complications included vomiting, idiopathic seizures, and pancreatitis, all of which resolved.
- Authors concluded that LPMR is a safe, effective, and minimally invasive alternative to open surgery for selected distal pancreatic masses in dogs.

In Buote 2023 et al., on laparoscopic vertical sleeve gastrectomy (LVSG), what was the most common intraoperative complication in the cadaver model?
🔍 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.

In Kennedy 2024 et al., which muscle group was most frequently damaged by the caudal portal?
🔍 Key Findings Summary
- 20 shoulders from 11 medium-to-large breed dogs evaluated
- Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
- Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
- Neurovascular safety:
- Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
- Only 2/20 shoulders (10%) had omobrachial vein penetrated
- Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
- Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

In Miller 2024 et al., on staple vs. hand-sewn feline GI techniques, what was the most common location of leakage for skin staple enterotomy (SSE)?
🔍 Key Findings
- Skin staple anastomosis (SSA) had comparable leak pressures to hand-sewn anastomosis (HSA) but required half the time to complete.
- Skin staple enterotomy (SSE) had significantly lower leak pressures than hand-sewn enterotomy (HSE) and failed in 12/20 constructs during pressure testing.
- HSE constructs took 8× longer to complete than SSE, but had much higher intraluminal pressure tolerance.
- All SSE constructs leaked from the center, with 35% leaking immediately and 60% showing catastrophic failure.
- SSA leakage occurred at the center in 40% of constructs, likely due to a learning curve in early samples.
- All constructs had higher pressures than normal physiologic intestinal pressure (4.0 mmHg ±2.0), except some SSEs with immediate leaks.
- Authors recommend SSA as a viable alternative with appropriate training but do not recommend SSE using the tested technique in live cats.
- Staple size and placement technique are key factors; smaller or more precisely placed staples may reduce leak risk.

In Wood 2024 et al., on knot security and locking throws, which suture material showed greater holding strength?
🔍 Key Findings
- Adding a single locking throw significantly increased holding security for specific knots, including the surgeon's throw (p = .0001) and square throw (p = .0002).
- For the Miller's throw (p = .166) and strangle throw (p = .808), no significant improvement was observed with a locking throw.
- After locking throw addition, all five knots leaked at similar pressures (p = .5233), and these pressures exceeded physiologic arterial pressures.
- Surgeon's throw without a locking throw had the lowest leak pressure (62.5 ± 46.2 mm Hg), below physiologic arterial values.
- The square throw without locking also leaked below physiologic pressures (148.7 ± 109.4 mm Hg), though it outperformed the surgeon's throw.
- Miller’s and strangle throws performed significantly better than square or surgeon’s throws without locking, achieving leak pressures >200 mm Hg.
- All knots used 2-0 polyglyconate monofilament (Maxon); no comparisons across suture types or sizes were performed.
- Authors concluded that correct tensioning and locking throw addition are key to safe vascular ligation. Miller’s, strangle, or slip knots are preferred for challenging surgical fields.

In Anderson 2025 et al., on liver hemostatic agents, what was reported postoperatively regarding complications from sponge use?
🔍 Key Findings
- Study Design: Prospective, randomized clinical trial of 45 dogs undergoing liver biopsy or lobectomy.
- Groups:
- Adhesive gelatin sponge (AG) group (n=22)
- Plain collagen sponge (PC) group (n=23)
- Main Results:
- At 5 minutes post-application, 10/20 PC dogs were still bleeding vs. 2/20 AG dogs (p = 0.0138).
- AG had significantly better adhesion scores (median 2 vs. 1, p < 0.001).
- Sponge dislodgement: 5/23 in PC group, 0/22 in AG group (p = 0.042).
- Time to 50% hemostasis: AG = 2 min, PC = 4 min 49 sec.
- Complications: No adverse events related to either sponge.
- Conclusion: Adhesive gelatin sponges offered superior intraoperative adhesion and hemostatic control during canine liver surgery compared to collagen sponges.

In Brisimi 2022 et al., on tracheal anastomosis tension, where did failure most commonly occur?
🔍 Key Findings
- Tracheal anastomoses in immature dogs failed at significantly lower distraction forces (44.91 ± 59.03 N) than in adults (149.31 ± 45.36 N; _P_ = .007).
- Immature tracheae tolerated significantly more elongation before failure (39.75 ± 5.45%) than adult tracheae (30.57 ± 7.19%; _P_ = .0012).
- All constructs failed by suture tearing through the annular ligament, primarily near the dorsal tracheal ring.
- Overlapping of tracheal ends was seen in 50% of specimens across both age groups, suggesting limitations in tissue apposition with the chosen technique.
- Simple continuous pattern using 2-0 polypropylene was used; this pattern provides superior tensile strength compared to simple interrupted, but apposition may be suboptimal.
- Tracheal elasticity in immature dogs may allow longer resections, but the lower tensile strength necessitates reinforcement.
- Annular ligament-cartilage technique with 4-mm suture spacing showed variable results; smaller bites and nylon suture may improve outcomes.
- Ex vivo setup using frozen-thawed tracheae is a limitation, but prior studies support comparability with fresh tissue.

In Fitzpatrick 2024 et al., on ESF for pelvic fractures in cats, what was reported regarding the need for revision surgery?
🔍 Key Findings
- External skeletal fixation (ESF) was successfully applied to a variety of pelvic fracture types in cats, including sacroiliac luxations and ilial body fractures.
- All fractures achieved radiographic union within 9 weeks, even in comminuted or complex configurations.
- No intraoperative or long-term complications were reported during the study period.
- Implant loosening was observed radiographically in 13% of cases, with 8% of pins found to be loose at frame removal.
- ESF enabled indirect fracture reduction using components as handles, with a limited open approach minimizing soft tissue disruption.
- No iatrogenic neurological deficits were observed, supporting safe pin placement near neurovascular structures, although some cats presented with pre-existing neurologic signs.
- No cases required revision surgery, and all cats underwent stabilization solely with ESF as per study inclusion criteria.
- Postoperative hospitalization ranged from 2 to 5 days, though no comparison to other fixation types was evaluated.

- All fractures achieved radiographic union; no unacceptable outcomes were reported
- 40% complication rate, mostly minor (82%), primarily pin-tract morbidity; major complications (7%) included osteomyelitis and refracture
- Open fractures had significantly more major complications than closed ones (P = .019)
- Use of intraoperative imaging (72% cases) reduced surgery time but did not improve alignment (P > .05)
- Median surgery time: 74 min with imaging vs. 100 min without (P = .046)
- TPA was lower than normal in both dogs and cats, but did not correlate with poor outcomes
- 62% had full clinical recovery, and 38% had acceptable outcomes at fixator removal
