BACKGROUND: The incidence of delayed gastric emptying (DGE) after esophagectomy is 10%-50%, which can interfere with postoperative recovery in the short-term and result in poor quality of life in the long term. Pyloric drainage is routinely performed to prevent DGE, but its role is highly controversial. The aim of this study was to report the rate of DGE after esophagectomy without pyloric drainage and to investigate its risk factors and the potential effect on recovery.
MATERIALS AND METHODS: Between January 2010 and January 2015, we analyzed 285 consecutive patients who received an esophagectomy without pyloric drainage. Possible correlations between the incidence of DGE and its potential risk factors were examined in univariate and multivariate analyses, respectively. The outcomes of DGE were reviewed with a follow-up of 3 mo.
RESULTS: The overall rate of DGE after esophagectomy was 18.2% (52/285). Among perioperative factors, gastric size (gastric tube versus the whole stomach) was the only significant factor affecting the incidence of DGE in the univariate analysis. The patients who received a whole stomach as an esophageal substitute were more likely to develop DGE than were patients with a gastric tube (13.2% versus 22.4%; P = 0.05). No independent risk factor for DGE was found in the multivariate analysis. The incidence of major postoperative complications, including anastomotic leak, respiratory complications, and cardiac complications, was also not significantly different between both groups, with or without DGE. Within 3 mo of follow-up, most patients could effectively manage their DGE through medication (39/52) or endoscopic pyloric dilation (12/52), with only one patient requiring surgical intervention.
CONCLUSIONS: In our study, the overall incidence of DGE is about 20% for patients undergoing esophagectomy without pyloric drainage. Compared with prior findings, this does not result in a significantly increased incidence of DGE. In patients with symptoms of DGE after esophagectomy, prokinetic agents and endoscopic balloon dilation of the pylorus can be effective, as indicated by the high success rate and lack of significant complications.
