Abstract
Background and study aims Endoscopic ultrasound (EUS)-guided drainage is a well-established procedure for peripancreatic fluid collections (PFC) that develop in the context of acute pancreatitis or following pancreatic surgery. Malignant ascites can occur in a loculated form resembling PFC causing a variety of symptoms, with limited treatment options. There is a paucity of data about application of EUS-guided drainage for these kinds of fluid collections. So far, only one report exists describing clinical success in three cases, using fully-covered self-expanding metal stents (FCSEMS). FCSEMS, however, have possible drawbacks, particularly if they have to remain in place for an indeterminate period of time. Herein, we describe EUS-guided drainage of loculated malignant ascites using double-pigtail plastic stents in two patients severely symptomatic from esophagogastric obstruction symptoms. Technical and clinical success was achieved in both cases without clinically significant complications including one case, where ongoing symptom control could be observed after 6 months of follow-up.
