It has been proposed that this might be related to gastric emptying. The aim of this study was to evaluate the relationship between preoperative upright reflux pattern, gastric emptying rate and outcome after laparoscopic fundoplication.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Patients presenting for antireflux surgery underwent 24-h ambulatory pH testing and dual-isotope radionuclide gastric emptying studies. Reflux pattern was determined by the acid exposure in the distal oesophagus (percentage of time at pH &amp;lt; 4) during supine and upright posture. Outcome after fundoplication was assessed by a standardized postal questionnaire administered at 3 months, and 1, 2 and 5 years after surgery.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Of 372 patients identified from a prospectively maintained database, 109 had upright reflux, 57 supine reflux and 206 bipositional reflux. Overall patient satisfaction was not influenced by reflux pattern at any time after surgery. Delayed gastric emptying was documented in 31\u00b70 per cent of patients, but there was no relationship with reflux pattern.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Patients with upright reflux did not have a less favourable outcome after fundoplication.
