“…In einer Subgruppenanalyse waren große chronische Ulzera (> 2 cm) und Patienten mit Hypotension wegen schwerer Blutung unabhängige Risikofaktoren für das Versagen einer weiteren endoskopischen Therapie. [23]. In ihrer Fallserie waren 5 therapierefraktäre blutende peptische Ulzera an klassischen Hochrisikopositionen lokalisiert (4 an der Bulbushinterwand und 1 an der kleinen Magenkurvatur) sowie eine Dieulafoy-Läsion im Duodenum.…”

The overall success rate of the OTSC system depends on the expertise, size, and location of gastroesophageal lesions and ranges from 66% to 75% in one small case series . The factors intrinsic to fistulas such as fibrosis can additionally impede the success of the OTSC system.…”

Whereas closure of a defect used to focus mainly on apposition of the perforation edges, we believe that the creation of an endoscopic omental patch may add strength and improve sealing of the perforation site.…”
