Delay in Oral Feeding is Associated With a Decrease in Anastomotic Leak Following Transhiatal Esophagectomy

The cervical anastomotic leak is a major complication of transhiatal esophagectomy and results in chronic strictures in up to half of patients. A change in postoperative protocol to delaying initiation of oral intake was made with the goal of reducing anastomotic leak rate and associated sequelae. A postoperative protocol change was applied to all patients undergoing elective transhiatal esophagectomy. Rate of anastomotic leak and anastomotic stricture, defined as defect in the esophagogastric anastomosis and narrowing of the anastomosis, respectively, were compared between pre- and post-change groups. Between 2004 and 2013, 203 patients underwent transhiatal esophagectomy with cervical anastomosis. Historically, oral intake was resumed on postoperative day 3, and during the course of the study, a change was made to the protocol to delay oral intake until 15 days postoperatively. Eighty-three patients were in the early oral feeding group (postoperative day 3), and 120 were in the delayed oral intake group (postoperative day 15). There was a statistically significant decrease in the rate of anastomotic leak from 14.5% to 4.2% between the early and delayed intake groups, respectively (P = 0.0089). There was also a trend (P = 0.05) towards a lower rate of anastomotic stricture in all patients in the delayed intake group (15.8%) compared with those in the early feeding group (27.7%). By increasing the time to postoperative oral feeding, we have noted an associated improvement in both immediate and long-term outcomes of elective transhiatal esophagectomy patients.
