Background
This study aimed to systematically evaluate the effect of early oral feeding (EOF) versus late oral feeding (LOF) on postoperative complications and rehabilitation outcomes for patients with esophageal cancer.
Methods
This study searched relevant literature published up to March 2023 by computer retrieval of PubMed, Embase, The Cochrane Library, and Web of Science. A meta-analysis was performed using Review Manager 5.4 software to compare the effects of EOF and LOF on postoperative complications and recovery outcomes of patients with esophageal cancer.
Results
The study included 14 articles, including 9 retrospective studies, 4 randomized controlled trials (RCTs), and 1 prospective study. The 2555 patients included in the study comprised 1321 patients who received EOF and 1234 patients who received LOF. The results of the meta-analysis showed that compared with the LOF group, the EOF group has a shorter time to the first flatus postoperatively (mean difference [MD], − 1.12; 95% confidence interval [CI], (− 1.25 to − 1.00; P < 0.00001), a shorter time to the first defecation postoperatively (MD, − 1.31; 95% CI, − 1.67 to − 0.95;, P < 0.00001], and a shorter hospital stay postoperatively (MD, − 2.87; 95% CI, − 3.84 to − 1.90; P < 0.00001). The two groups did not differ significantly statistically in terms of postoperative anastomotic leakage rate (P = 0.10), postoperative chyle leakage rate (P = 0.10), or postoperative pneumonia rate (P = 0.15).
Conclusion
Early oral feeding after esophageal cancer surgery can shorten the time to the first flatus and the first defecation postoperatively, shorten the hospital stay, and promote the recovery of patients. Moreover, it has no significant effect on the incidence of postoperative complications.
