Postoperative Complications in Patients with Frailty Syndrome Undergoing Esophagectomy-A Systematic Review with...

Introduction: Frailty syndrome is an increasingly recognized condition that affects a considerable proportion of elderly patients, particularly those undergoing major surgeries. In this meta-analysis, we aimed to systematically review and pool data from cohort studies to assess the effect of frailty on the clinical outcomes of patients undergoing esophagectomy for esophageal cancer. Methods: Major online medical databases such as PubMed, Embase, Scopus, and Web of Science were searched to gather all studies on the clinical outcomes of patients with frailty syndrome who underwent esophagectomy due to esophageal cancer. The study included articles published up to March 2026. Finally, 15 articles matched the required criteria and were included in this meta-analysis. Results: The pooled odds ratio for surgery-related mortality in patients with frailty syndrome and esophageal cancer undergoing esophagectomy has been established at 4.03 (Lower Limit: 2.20; Upper Limit: 7.38; p-value < 0.05). The pooled odds ratio for surgery-related postoperative pneumonia in patients with frailty syndrome and esophageal cancer undergoing esophagectomy has been established at 1.86 (Lower Limit: 1.16; Upper Limit: 2.98; p-value < 0.05). The pooled odds ratio for surgery-related postoperative cardiac complications in patients with frailty syndrome and esophageal cancer undergoing esophagectomy has been established at 1.73 (Lower Limit: 1.54; Upper Limit: 1.94; p-value < 0.05). Conclusions: Frailty is a powerful predictor of mortality in patients undergoing esophagectomy, with frail individuals facing nearly four times higher odds of death. This underscores the urgent need to integrate frailty assessments into standard preoperative screening to enhance risk stratification and optimize perioperative decision-making. A multidisciplinary approach is essential to improving resilience, recovery, and long-term survival in frail esophageal cancer patients. Future large-scale prospective trials should focus on standardizing assessment tools and evaluating the lasting impact of tailored interventions to ultimately enhance patient outcomes.
