Background: To reduce the clinical and economic burden of complications after gastrectomy for gastric cancer, specific complications should be targeted to effectively allocate healthcare resources for quality improvement and preventive measures. The aim of this study was to assess the impact of complications on clinical outcomes. Methods: This was a retrospective multicentre study of patients who underwent (sub)total gastrectomy for gastric or junctional adenocarcinoma at 43 centres in 16 countries between 2017 and 2021. Outcomes were escalation of care, reoperation, prolonged hospital stay (greater than the 75th percentile), readmission, and 30-day mortality. Adjusted relative risks and population attributable fractions were estimated for specific complication-outcome pairs. The population attributable fraction represents the percentage reduction in the frequency of an adverse outcome if a complication could be completely prevented in the population. Results: In total, 7829 patients were included. Postoperative complications occurred in 1884 patients (24.1%). The most frequent complications were pulmonary complications (436 patients (5.6%)), anastomotic leakage (363 patients (4.6%)), and abdominal collection (301 patients (3.8%)). Anastomotic leakage, cardiac complications, and pulmonary complications had the greatest impact on 30-day mortality (population attributable fraction 26.6% (95% c.i. 14.5% to 38.6%), 18.7% (95% c.i. 9.4% to 28.0%), and 15.6% (95% c.i. 12.0% to 30.0%) respectively). Anastomotic leakage and pulmonary complications had the greatest impact on escalation of care (population attributable fraction 26.3% (95% c.i. 20.6% to 32.0%) and 18.4% (95% c.i. 11.7% to 25.2%) respectively), whereas anastomotic leakage and intra-abdominal bleeding had the greatest impact on reoperation (population attributable fraction 31.6% (95% c.i. 26.4% to 36.9%) and 8.5% (95% c.i. 5.5% to 11.5%) respectively). Most of the studied complications contributed to a prolonged hospital stay, whereas the contribution of complications to readmission did not exceed 15.9%. Subgroup analysis showed regional variation in the impact of complications. Conclusion: Anastomotic leakage had the largest overall negative impact on clinical outcomes after gastrectomy for gastric adenocarcinoma. Reducing the incidence of anastomotic leakage and pulmonary complications would have the most impact on the burden of complications.
