Endoscopic ultrasonography-guided drainage combined with trans-duodenoscope cyclic irrigation technique for walled-off pancreatic necrosis.

BACKGROUND

Endoscopic ultrasonography-guided drainage has been established as a good treatment modality in the management of walled-off pancreatic necrosis, but the unmanageable infection of postoperation is still a thorny problem due to the poor drainage ability for solid necrotic debris only through transmural stent and nasocystic catheter.

AIMS

Introduce a novel therapeutic method, namely endoscopic ultrasonography-guided drainage combined with cyclic irrigation technique in managing patients with walled-off pancreatic necrosis.

METHODS

18 patients with severe acute pancreatitis complicated with walled-off pancreatic necrosis received treatment with endoscopic ultrasonography-guided drainage combined with cyclic irrigation were involved in this retrospective study.

RESULTS

17 of 18 patients with walled-off pancreatic necrosis were treated by this new therapeutic method. Subsequent surgery was performed in 1 case due to uncontrolled infection, complications such as perforation, bleeding or multiple organ failure were not observed. Treatment success rate was high (16 in 17, 94.12%).

CONCLUSION

Endoscopic ultrasonography-guided drainage combined with cyclic irrigation is an effective treatment option for symptomatic walled-off pancreatic necrosis to facilitate drainage and obviate the need for subsequent surgery or endoscopic necrosectomy.
