🔍 Key Findings
PL-30 group (partial, TA30-V3 wedge):
- 100% leaked
- Median leakage pressure: 10 cm H₂O
- Most failures from periphery of staple line
PL-60 group (partial, TA60-3.5):
- 100% leaked
- Median leakage pressure: 18 cm H₂O
- Better than PL-30 (p = .006)
TL-30 group (total, TA30-V3):
- Only 1 of 11 leaked (at 22 cm H₂O)
- All others resisted pressures >50–65 cm H₂O
- Significantly higher leakage pressure than both PL groups (p < .001)
Odds ratios (leakage vs TL-30):
- PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
- PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)
Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.
