[The treatment of walled-off pancreatic necrosis. Review].

Walled-off pancreatic necrosis is a late complication of severe acute pancreatitis that generally needs some interventions. The aim of this review is to analyse the indications, technical aspects and limits of these therapeutic options. The development of the walled-off pancreatic necrosis needs 4-6 weeks from the onset of the disease. The necrosectomy is recommended after this time. Endoscopic necrosectomy offers good results if the necrosis is in retrogastric or retroduodenal localisations. Open necrosectomy can be performed through the gastrocolic ligament or the mesocolon. It is suggested to complete necrosectomy with open or closed omental bursa drainage or packing. The transgastric necrosectomy does not need external drainage. Surgical procedures can be performed with laparoscopy either. In localized necrosis other minimal invasive approaches can be used.

CONCLUSIONS: In addition to the transluminal endoscopic or minimal invasive necrosectomies different types of surgical procedures has an important role in the treatment of walled-off pancreatic necrosis. Orv. Hetil., 2016, 157(47), 1866-1870.
