Introduction Pancreatic fluid collection (PFC) is a common complication of acute pancreatitis. Endoscopic ultrasound (EUS)-guided drainage, which is often followed by direct endoscopic necrosectomy (DEN), has become the primary approach to treat PFC, including pancreatic pseudocysts (PP) and walled-off necrosis (WON). We aimed to determine retrospectively the short- and long-term results of patients treated in our endoscopy unit and to identify parameters that are associated with treatment efficacy and outcome.
Methods The data of 41 consecutive patients with post-pancreatitic PFC, who underwent endoscopic transmural intervention between 2014 and 2016, were analyzed retrospectively. After an initial EUS-guided puncture, one or more plastic stents were placed and DEN was performed if necrotic tissue remained.
Results The mean diameter of the PFC was 74.0 ± 4.8 mm. Of the PFCs, 29.3% were classified as PP and 70.7% as WON. Altogether, 196 transmural endoscopic procedures were performed, including 73 endoscopic necrosectomies in a subgroup of 21 patients (20 WON, 1 PP). Initial technical success was achieved in 97.6% of patients and the short-term clinical success rate was 90.2%. The long-term clinical success rate was 82.9%, since four patients died from septic shock and/or multiple organ failure and three patients developed recurrent PFC some months after the initial discharge from endoscopic treatment. Procedural complications were registered in 9 patients during 10 of 196 endoscopic procedures (5.1%): bleeding (6), cardiorespiratory insufficiency (2), perforation with pneumoperitoneum (1), aspiration with respiratory insufficiency (1), and non-perforating superficial damage of the gastric wall (1). Neither the size of the PFC nor the initial value of C-reactive protein (CRP) or other biochemical markers were correlated with efficacy or outcome of treatment. Only the cumulative number of days with CRP > 50 mg/L significantly correlated with the number of follow-up endoscopic sessions and DEN. Fungal colonization of PFC correlated significantly (p < 0.05) with the risk of mortality (44% vs. 0%), need for intensive care treatment (66.7% vs. 25%), and sepsis (55.6% vs. 12.5%).
Conclusions We confirm that EUS-guided drainage followed by DEN in patients with solid necrotic material is an effective and relatively safe therapeutic approach. Prolonged elevation of CRP and fungal colonisation of the PFC are associated with a worse course of the disease.
