Single transluminal gateway transcystic multiple drainage for extensive walled-off pancreatic necrosis - a single-centre experience.

Introduction: In last three decades we have observed development in minimally invasive techniques in the treatment of walled-off pancreatic necrosis (WOPN). Endoscopic treatment of the consequences of acute necrotising pancreatitis is a accepted and common minimally invasive method.

Aim: Evaluation of the efficiency and safety of the innovative endoscopic treatment method (single transluminal gateway transcystic multiple drainage - SGTMD) in patients with extensive walled-off pancreatic necrosis.

Material and methods: The retrospective analysis of 114 consecutive patients with symptomatic WOPN, who were treated endoscopically in our medical centre between 2011 and 2016.

Results: Single transluminal gateway transcystic multiple drainage was performed in 21/114 (18.42%) patients. Endoscopic necrosectomy under fluoroscopic guidance was performed in 12/21 (57.14%) patients. Complications of treatment appeared in 7/21 (33.33%) patients. The most common of complication was upper gastrointestinal bleeding treated conservatively with packed red blood cells transfusions. There were no deaths. Therapeutic success was reached in 20/21 (95.24%) patients. No patient required surgery. The medium time of follow-up was 22 months (16-47). During the observation the recurrence of pancreatic fluid collection was noticed in 1/21 (4.76%) patients. Long-term success of endoscopic treatment was achieved in 19/21 (90.47%) patients.

Conclusions: Single transluminal gateway transcystic multiple drainage is an effective method of endoscopic treatment for extensive walled-off pancreatic necrosis with an acceptable amount of complications. However, the method of interventional treatment of pancreatic necrosis should depend not only on the location of necrosis, but also on the experience of the medical centre.
