Localización endoscópica del cambio de mucosa escamoso-columnar en pacientes con diferentes grados de reflujo gastroesofágico patológico / Endoscopic location of squamous columnar mucosal junction in patients with gastroesophageal reflux

The location of the squamous columnar mucosal junction was prospectively studied by endoscopy in 347 subjects with normal upper gastrointestinal endoscopy, 117 patients with chronic gastroesophageal reflux without esophagitis, 117 patients with erosive esophagitis, 63 patients with short Barret's esophagus and 28 patients with an extensive Barret's esophagus. No differences in the mucosal junction location were observed between controls and patients with gastroesophageal reflux or erosive esophagitis. In patients with Barret's esophagus, the junction was more proximal. In women, the junction was three cm more proximal than in men, probably due to their shorter stature. Women have a proximal squamous columnar mucosal junction than men
