Abstract
Background
The recommended treatment of infected walled-off necrosis (WON) in necrotizing pancreatitis entails a step-up treatment approach starting with endoscopic necrosectomy (ETDN).
Aims
To report a small number of cases from 2013 to 2016 that were not amenable to or failed to respond to ETDN, and to describe a new, minimally invasive technique that may be a promising supplement to ETDN in this difficult patient population.
Methods
Using the Seldinger technique, a fully covered self-expanding metal stent (SEMS) was placed percutaneously in order to drain, irrigate, and debride WON. After resolution, the stent was removed. We reviewed electronic patient records and defined clinical success as complete WON resolution with removal of internal as well as percutaneous drains and stents.
Results
Five patients underwent treatment with SEMS placement. The mean length of the WON was 33.4 cm. Clinical success was achieved in four patients after an average of 5.75 necrosectomy sessions. One patient died from severe sepsis. Adverse events included severe abdominal pain and productive cutaneous fistulae (two patients).
Conclusions
In our small case series, endoscopic necrosectomy through a percutaneous SEMS seemed beneficial and safe in the treatment of infected WON.
