Abstract
Background/AimsThe management of walled-off necrosis (WON) has undergone a paradigm shift from surgical to nonsurgical modalities. Real-world data on the management of symptomatic WON are scarce. MethodsProspectively collected data of symptomatic WON cases were retrospectively evaluated. The treatment modalities used were medical management alone, percutaneous catheter drainage (PCD) or endoscopic drainage (ED), or a combination of PCD and ED. We compared clinical outcome among these modalities. ResultsA total of 264 patients were evaluated. The most common indications for drainage were pain and fever. Of the patients, 28% was treated with medical therapy alone, 31% with ED, 37% with PCD, and 4% with a combined approach. Technical success and clinical success were achieved in 93% and 91% of patients in the endoscopic arm and in 90% and 81% patients in the PCD arm, respectively (p=0.0004 for clinical success). Lower rates of complications (7% vs. 22%, p=0.005), readmission (20% vs. 34%, p=0.04), and mortality (4% vs. 19%, p=0.0012), and shorter hospital stay (13 days vs. 19 days, p=0.0018) were observed in the endoscopic group than in the PCD group. ConclusionsED of WON is better than PCD and is associated with lower mortality, fewer complications, and shorter hospitalization.
