SL yield was 16.8% and did not differ between groups or over time. In patients undergoing attempted resection with prior SL, the curative resection rate did not differ between subtypes. In patients undergoing attempted resection without prior SL, the curative resection rate was less in GBC compared with DC or HC. After matching cohorts by inverse probability weighting, prior SL was associated with curative resection in GBC only (odds ratio [OR], 2.41, 95% CI, 1.36\u20104.27). On multivariable regression analysis, elevated carbohydrate antigen 19\u20109 (CA 19\u20109), low serum albumin, and GBC were strong predictors of distant disease on SL.
