Surgical intervention in infected necrotising pancreatitis generally consists of necrosectomy via laparotomy. The morbidity and mortality after this procedure might be reduced by minimally invasive strategies. The 20 hospitals of the Dutch Acute Pancreatitis Study Group are currently enrolling patients in a randomised trial to compare (a) laparotomy with necrosectomy and continuous postoperative lavage with (b) CT-guided or endoscopic transgastric drainage, if necessary, followed by videoscopic assisted retroperitoneal debridement (VARD): the PANTER trial ('pancreatitis, necrosectomy versus a minimally invasive step-up approach'). The primary endpoint is the proportion of patients suffering from major postoperative morbidity and mortality. Patients with (suspected) infected necrotising pancreatitis can be put forward for participation in the trial in one of the 20 participating centres.
