Could a poor outcome of gastro-oesophageal reflux surgery be related to lactase deficiency?

Complications of surgery for gastro-oesophageal reflux disease can provoke severe symptoms that condemn the patient to a very poor quality of life. A similar clinical picture is presented among patients with lactase deficiency, which is highly prevalent today. In view of these considerations, we consider to what extent lactase deficiency may influence the symptoms observed following gastro-oesophageal reflux disease intervention, and to what extent these could be avoided by the prior identification and treatment of this type of patient.
