Impact of high body mass index on surgical outcomes and long-term survival among patients undergoing esophagectomy: A meta-analysis

Background: The impact of high body mass index (BMI, >23/25 kg/m2) on surgical outcomes and prognosis in patients with esophageal carcinoma (EC) after undergoing esophagectomy remains controversial. We herein conducted a systematic review and meta-analysis to determine the relationship between high BMI and surgical outcomes and prognosis in patients undergoing esophagectomy for EC.
