Neither low-calorie diet nor vertical banded gastroplasty influence gastro-oesophageal reflux in morbidly obese patients.
OBJECTIVE
Investigate the effect of a liquid diet, and of vertical banded gastroplasty, on gastro-oesophageal reflux in morbidly obese patients.


METHODS
Prospective study, patients being their own controls.


METHODS
University hospital, Sweden.


METHODS
25 morbidly obese patients, listed for vertical banded gastroplasty.


METHODS
24 hour ambulatory intra-oesophageal pH-monitoring three weeks before operation and repeated after 10-14 days on a liquid very low calorie diet, and finally three weeks after operation, while still on a liquid very low calorie diet.


METHODS
Percentage of time that pH in the oesophagus was < or =4.


RESULTS
There were no changes in the amount of reflux, either after a liquid diet or after vertical banded gastroplasty.


CONCLUSIONS
Neither the liquid diet nor vertical banded gastroplasty alone had any appreciable effect on gastro-oesophageal reflux.
