Endoscopic ultrasound-guided treatment of pancreatic fluid collections with lumen apposing metallic stents: lessons learned

Abstract

Pancreatic fluid collections are common pancreatitis complications that frequently require drainage. Endoscopic ultrasound-guided placement of expandable lumen apposing metallic stents has recently emerged as an effective and less invasive treatment option. It is associated with less morbidity, lower costs, and faster clinical recovery than other therapeutic modalities. Nevertheless, this procedure may result in severe complications such as bleeding, buried stent syndrome, and prosthesis dislodgement (with perforation and peritoneal leakage). We performed 108 EUS-guided drainages with lumen apposing metallic stents for the treatment of pancreatic fluid collections with 8 complications and only two cases that required urgent surgical procedures resulting in one fatality. We present this two severe complications submitted to surgical treatment and discuss potential signs of alarm that must be taken under consideration before choosing a treatment modality.
