Is a gastric drainage procedure necessary at the time of antireflux surgery?
BACKGROUND
Gastroesophageal reflux is part of a generalized foregut motility disorder, which may also include delayed gastric emptying. With persistence of gastroesophageal reflux, or the presence of complications, including recurrent aspiration syndrome and esophageal stricture formation, surgical correction may be indicated. It is uncertain whether a procedure to resolve delayed gastric emptying is indicated at this time as well.


METHODS
Sixty-seven children with proven gastroesophageal reflux had preoperative gastric emptying assessed using 99Technetium-Sn-colloid labelled milk. Delayed gastric emptying was defined as a gastric residual activity of more than 40% at 2 hours after feeding. The antireflux operation was a partial anterior fundoplication. Postoperative milk scans assessed the effect of surgery on gastric emptying.


RESULTS
Gastric emptying at 2 hours improved overall from a median of 22% before surgery to 17% after surgery. In 17 patients delayed gastric emptying was identified before surgery; in 15 of those it returned to within normal limits after surgery. In 50 children with normal gastric emptying before surgery (gastric residual activity at 2 hours 16%), 14 (28%) showed delayed gastric emptying in the postoperative scan.


CONCLUSIONS
Delayed gastric emptying is common in children who undergo surgery for gastroesophageal reflux disease. A partial anterior fundoplication antireflux operation improves gastric emptying to within normal limits in the majority (88%) in this group, rendering a synchronous gastric drainage procedure unnecessary.
