Potential of Absorption, Capillary Effect and Sponge-Effect in Endoscopic-Assisted Therapy for Leaks and Fistulas

1.1. Introduction: Anastomotic leaks and fistulas as well as perforations do lead to increased morbidity and mortality. Several interventional endoscopic techniques such as stents, clips, endoscopic suturing and endoscopic vacuum therapy, can help in reducing an unfavorable outcome of these patients, using a differentiated management of leakages. An important feature of these therapeutic options is the contineous removal of fluid from the fistula or abscess cavity in order to heal the defect and prevent subsequent complications. The objective of this study is the investigation of technical and conceptual modifications of the established Endo-sponge therapy and their feasibility.
