Reasons and risk factors for irregular‐interval endoscopic variceal sclerotherapy in patients with esophageal variceal bleeding

Endoscopic variceal sclerotherapy (EVS) is usually carried out at weekly intervals in patients with esophageal variceal bleeding (EVB). However, some patients receive sclerotherapy at irregular intervals. In this study we aimed to elucidate the reasons and risk factors for irregular‐interval sclerotherapy in patients with EVB, and to evaluate the safety and efficacy of interrupted irregular intervals in these patients.
