The distribution was as follows: Type I, 524 cases (63%); Type II, 53 (6%); Type III, 171 (20%); and Type IV, 90 (11%). Compared with Types II\u2013IV, Type I patients were younger, more often male, had longer symptom duration, more heartburn, fewer comorbidities, and more severe esophagitis. Strictures were rare, and surgery was more often indicated due to refractoriness to medical treatment. Type I cases had higher rates of laparoscopic surgery and Toupet fundoplication, with shorter operative times, fewer complications, and shorter hospital stays. They had lower rates of postoperative dysphagia. Risk factors for postoperative dysphagia included Types II\u2013IV hernia (OR 1.676,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002), preoperative dysphagia (OR 1.898,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.006), and esophageal strictures (OR 3.102,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.016).
