Guessing the future of endoscopic drainage of walled-off necrosis

The endoscopic treatment of walled-off necrosis is rapidly evolving concurrently with an increasing number of endoscopic techniques, devices, and combined procedures. Thus, there is a growing armamentarium of alternatives for those patients in whom the conventional direct endoscopic necrosectomy is not enough. However, when the patient reaches this point he enters in an unexplored field and choosing the correct option can be challenging. Furthermore, there is no consensus on the number of endoscopic procedures to perform before considering that direct endoscopic necrosectomy has failed and therefore another strategy should be considered.
