Key result
New BMI-based preoperative risk score strongly correlates with postoperative complications following laparoscopic gastrectomy.
Why the study?
No validated method for preoperative risk assessment in laparoscopic gastrectomy had been reported despite increasing complexity of oncological procedures.
Does a new preoperative risk score model predict postoperative complications better than conventional scores in patients undergoing laparoscopic gastrectomy?
Comparison
New preoperative risk score model and contour map vs conventional risk scores such as E-PASS and POSSUM
Design
Cohort study with multivariate analysis
Follow-up
Postoperative period

May support preoperative risk stratification for laparoscopic gastrectomy; leaves open prospective validation before clinical adoption.
Cohort (n=214)
Does a new preoperative risk score model predict postoperative complications better than conventional scores in patients undergoing laparoscopic gastrectomy?
Effect estimate: r = 0.948
A new 2-dimensional risk estimation model using BMI and 5 preoperative factors accurately predicts postoperative complications in laparoscopic gastrectomy.
Ohkura et al. (2015) conducted a cohort in Laparoscopic gastrectomy (n=214). Preoperative risk score and contour mapping vs. Conventional risk scores (E-PASS and POSSUM) was evaluated on Postoperative complications (r = 0.948). A new preoperative risk score using BMI and 5 categorical variables was significantly correlated with postoperative complication rates (r = 0.948) following laparoscopic gastrectomy.
