Quiz Question
In Monnet 2023 et al., on barbed vs conventional suture in vesicourethral anastomosis (VUA), what was the key finding regarding leakage pressure?
🔍 Key Findings
- Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
- UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
- UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
- Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
- No suture breakage or urethral narrowing occurred in either group.
- Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
- Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
- UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.

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 Pilot 2022 et al., on closure methods in sternotomy, what was concluded regarding closure technique choice in large dogs?
🔍 Key Findings
- Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
- No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
- Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
- Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
- Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
- Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
- Infection rate was low (2.7%), and not significantly different between wire and suture.
- Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.

In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what was the most common **histopathologic diagnosis** among the excised pulmonary lesions?
🔍 Key Findings
- TA lung lobectomy was feasible in dogs ≥3 kg, including those with lesions up to 10 cm.
- 12 intraoperative complications (40%) occurred, with 6 dogs (20%) converted to open thoracotomy, mainly due to adhesions or inability to isolate lobes.
- Postoperative complications occurred in 8 dogs (27%), most were mild (63%), and only 1 death (3%) was reported.
- Median hospitalization was 47 hours; 29/30 dogs were discharged successfully.
- One-lung ventilation (OLV) was attempted in 7 dogs but successfully maintained in only 4.
- Linear staplers had shorter surgery times (median 57.5 min) than endoscopic staplers (80 min).
- Histopathology confirmed neoplasia in 77% of cases, most commonly papillary and bronchioalveolar carcinoma.
- TA lobectomy allows MIS in smaller dogs or with large lesions, avoiding need for full thoracotomy or complex anesthesia/stapling.

In Maeta 2022 et al., on total cystectomy in cats, how was urinary incontinence managed postoperatively?
🔍 Key Findings
- First reported case of total cystectomy and bilateral cutaneous ureterostomy in a cat using a modified Toyoda technique.
- Histologically complete tumor resection was achieved, with tumor-free ureter and urethral margins >20 mm.
- The modified Toyoda technique involved shaping the ureter into a fish-mouth aperture and anastomosing it to a rectangular skin defect for stomal formation.
- Incontinence was managed using a diaper changed every 6–8 hours, with no dermatological complications.
- Obstruction of the right ureter occurred 14 months post-op, associated with a subcutaneous nodule at the anastomosis site.
- Despite incontinence, owner satisfaction and perceived quality of life were high, with the cat living ~16 months post-op.
- The stents were removed on days 7 (left) and 28 (right) postoperatively, with initial patency maintained until 14 months.
- This surgical approach may offer palliative or curative benefit for feline trigonal TCC where partial cystectomy is not feasible.

In Hertel 2025 et al., on portal venotomy for insulinoma, what material and technique were used to close the venotomy site?
🔍 Key Findings
- Portal venotomy enabled successful en bloc resection of a pancreatic insulinoma and associated thrombus in the portal vein, a novel approach in veterinary literature.
- Temporary portal vein occlusion (15 min) was well tolerated, causing only transient small intestinal congestion without lasting hemodynamic compromise.
- No intraoperative hemorrhage occurred following vascular isolation and venotomy repair with 5–0 polypropylene in a simple continuous pattern.
- Postoperative complications were minimal, with only moderate pancreatitis managed medically and no portal hypertension observed on follow-up imaging.
- Histopathology confirmed insulinoma, with no initial metastasis; CT at 6 months revealed hepatic and peritoneal metastases but no local recurrence at the venotomy site.
- Portal vein luminal stenosis occurred post-repair but was clinically insignificant.
- Advanced CT imaging and 3D printed modeling significantly enhanced surgical planning and anatomical assessment.
- Surgical excision achieved good short-term outcomes, and the dog was alive and euglycemic one year later despite metastatic disease.
