INTRODUCTION
•Assessing staple line straightness after a sleeve gastrectomy (SG) is difficult
•The specific relationship between staple line straightness and patient-reported outcome measures (PROMs) is unknown
Hypothesis: increased variance in the staple line (corkscrewing) is associated with worse eating-related symptoms, reflected by lower PROMs scores.
METHODS
•SG patients between 10/2023-07/2024 were included if they had both specimen measurements and postoperative BODY-Q surveys
•Staple line variance was calculated by measuring the distance from the greater curvature to the staple line at 3 points on the resected specimen
•Higher variance indicated “corkscrewing”
•BODY-Q eating-related symptoms, a validated 15-item PROM, were assessed within 12 months with higher scores representing fewer symptoms and better health
•A Spearman correlation was used to compare staple line variance and BODY-Q scores
RESULTS
•34 patients were included
•There was a mild negative association between BODY-Q eating-related symptoms scores and resected stomach staple line variance (ρ = −0.29), which was not statistically significant (p=0.1)
•The average greater curvature length was 23.2 ± 3.1 cm with the proximal measurement being the longest and the distal measurement being the shortest
• The distal measurements had the greatest difference between measurements at -0.7 cm
CONCLUSIONS
•After SG, staple line variance on the resected stomach specimen did not significantly impact postoperative eating-related symptoms
•This suggests that measuring staple line variance on the resected stomach specimen may not accurately reflect the in-situ staple line
Future Directions:
•Larger studies are needed to validate these findings
•Standardized techniques for measuring staple line straightness are needed
