In Poggi 2024 et al., on laparoscopic resection of pancreatic masses in dogs, what was the median operative time for laparoscopic pancreatic mass resection?
🔍 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 Gollnick 2024 et al., on TCTF risk with Arthrex STS in TPLO, what percentage of dogs developed transcortical tibial fractures?
🔍 Key Findings
- 42% of dogs (33/78) treated with Arthrex 3.5 mm STS during TPLO developed radiographic TCTF
- TCTFs occurred exclusively distal to the osteotomy
- 14% of screws (36/250) distal to the osteotomy were associated with TCTFs
- 6% of dogs with TCTFs developed major complications (e.g., complete tibial fracture requiring surgical revision)
- Angulation of cortical STS screws, especially in the distal plate holes, was a key contributor to complications
- Locking screws were also involved, but cortical screws angled improperly were overrepresented in serious outcomes
- Revision recommendations included preemptive fixation for large TCTFs or angulated screw placements
- Use of non-self-tapping screws (NSTS) previously showed a <1% TCTF rate, supporting higher risk with STS

In Toth 2026 et al., on GIFB ultrasound accuracy, which factor was identified as most influential in determining success of laparoscopic-assisted intestinal surgery?
🔍 Key Findings
- Abdominal ultrasonography accurately identified foreign body type (96.8%) and shape (93.5%), demonstrating strong diagnostic agreement with surgical findings.
- Localization accuracy for foreign bodies was lower (77.4%), indicating moderate reliability for determining exact GI segment involvement.
- Ultrasound consistently underestimated foreign body size, meaning surgical planning should account for potential larger true dimensions.
- Overall success of laparoscopic-assisted intestinal surgery (LAIS) was 53.3% (16/30 dogs), with the remainder requiring conversion to open laparotomy.
- Non-linear foreign bodies were more successfully removed laparoscopically (60.9%) than linear foreign bodies (28.6%).
- Foreign bodies located at the caudal duodenal flexure were not successfully removed via LAIS (0%), representing a key anatomic limitation.
- Ultrasound detected intestinal adhesions with ~80% accuracy, although sensitivity was lower (66.7%), meaning some adhesions were missed preoperatively.
- Foreign body location and presence of adhesions were the most important predictors of LAIS success, making preoperative ultrasound valuable for surgical decision-making.

In Altwal 2026 et al., on limb sparing review, which complication is most commonly associated with limb-sparing surgery in dogs?
🔍 Key Findings
- Limb-sparing surgery aims to preserve limb function after resection of diseased bone, most commonly for appendicular osteosarcoma but also for non-repairable fractures causing critical bone defects.
- Survival outcomes after limb-sparing can be comparable to limb amputation, providing an alternative for owners who decline amputation or for dogs poor candidates for amputation.
- Techniques fall into two main categories: reconstruction of the bone defect or procedures that avoid reconstruction, depending on tumor location and surgical strategy.
- Common reconstructive techniques include cortical allografts, endoprostheses, bone transport osteogenesis, vascular or non-vascular autografts, and tumor-treated autografts.
- Non-reconstruction procedures include partial scapulectomy, partial ulnectomy, or limb shortening, which preserve limb function without rebuilding the bone defect.
- Major contraindications include detectable metastatic disease and extensive soft tissue involvement, although criteria such as pathologic fracture remain controversial.
- Complications are common and include infection, biomechanical failure, and local tumor recurrence, often due to extensive surgery, implants, chemotherapy-associated immunosuppression, and limited soft tissue coverage.
- Technique selection depends on anatomical site, available equipment, surgeon expertise, and owner factors, and comparative outcome data for many techniques remain limited.

In Mullen 2023 et al., on microvascular perfusion, which metric differed significantly between obstructed and healthy intestines?
🔍 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.

In Calabria 2026 et al., on ovariectomy biomarkers, which inflammatory biomarker showed an early postoperative peak after laparoscopic ovariectomy and returned to baseline by postoperative day 7?
🔍 Key Findings
- Laparoscopic ovariectomy produced a milder inflammatory response than open ovariectomy, supporting the benefits of minimally invasive surgery.
- Twenty-six healthy anestrus bitches were randomized equally to laparoscopic (LAP) or open (OPEN) ovariectomy in a prospective, blinded clinical trial.
- IL-6 increased rapidly after laparoscopy but returned to baseline by 7 days, whereas OPEN surgery produced a later, more prolonged elevation.
- Reactive oxygen metabolites (d-ROMs) remained higher after OPEN surgery, while LAP caused only a transient postoperative increase.
- Biological antioxidant potential (BAP) increased only in the OPEN group by postoperative day 7, suggesting a compensatory response to greater oxidative stress.
- PON-1 decreased after surgery in both groups, remaining lower in LAP through day 7, indicating that its interpretation as an inflammatory marker remains complex.
- LAP required longer operative time (35 vs 25 minutes; p = .008) but resulted in significantly smaller total incision length (1.5 vs 2.5 cm; p < .001).
- No intraoperative or postoperative surgical or anesthetic complications occurred in either treatment group.

🔍 Key Findings
- Short-term resolution of hypercalcemia occurred in 97.8% (44/45) of dogs.
- Long-term cure rate was 93.3%, comparable to traditional bilateral neck exploration.
- Postoperative hypocalcemia was observed in only 15.6%, which is lower than traditional approaches (36–63.8%).
- Permanent hypocalcemia occurred in 4.4%, requiring lifelong calcitriol supplementation.
- Minimally invasive approach had median surgical times of 26 min (unilateral) and 45.5 min (bilateral).
- Most lesions were adenomas (54.8%), followed by hyperplasia (27.4%) and carcinomas (3.2%).
- Ultrasound identified 98.4% (61/62) of abnormal glands, supporting it as the preferred imaging modality.
- One death due to non-compliance with calcitriol, emphasizing importance of postoperative management.

In Buote 2023 et al., on laparoscopic gastrectomy in cats, what complication was **not** observed in either live patient after surgery?
🔍 Key Findings
- LVSG was feasible in 9/10 feline cadavers with successful stapled gastrectomy and minimal technical complications.
- Stenosis at the incisura angularis occurred in 2/10 cadavers, associated with staple placement too close to the lesser curvature.
- Leak testing was negative in 8 cadavers and both live cats, indicating effective staple sealing.
- Mean stomach resection was ~28%, though less than human standards (~75–80%) for metabolic effects.
- Surgery was performed safely in two live feline subjects, with no intraoperative or postoperative complications over a 6-month follow-up.
- Technique refinements included orogastric tube placement and custom 3D-printed cannulas to improve staple line accuracy and avoid stenosis.
- Tri-Staple purple cartridges provided graduated compression suited for feline gastric tissue thickness (~2.5 mm).
- No need for staple line oversew in live cats; staple-only closure proved safe in this short-term study.
