Background: Long-term transmural double-pigtail stent (DPS) placement is recommended for patients with disconnected pancreatic duct syndrome (DPDS) and peripancreatic fluid collections (peri-PFCs). The long-term safety and efficacy of indwelling DPSs were evaluated., Methods: Medical files of patients treated with DPS for DPDS-associated peri-PFC and with a follow-up ≥ 48 months were reviewed. Early ( < 30 days) and late complications of DPS placement were evaluated and the primary endpoint, i. e., incidence of late complications per 100 patient-years of follow-up, was calculated. Short- and long-term success rates of endoscopic treatment and rate of peri-PFC recurrence were among secondary endpoints., Results: From 2002 to 2014 we identified 116 patients, with mean (SD) follow-up of 80.6 (34.4) months. Among early complications (n = 20), 6 occurred peri-interventionally. Late complications (n = 17) were mainly pain due to DPS-induced ulcer or erosion (n = 10) and 14 of these were treated conservatively or by stent removal; 2 gastro-pancreatico-colo-cutaneous fistulas and 1 persisting bleed required surgical intervention. No DPS-related deaths were recorded. The incidence rate (95 %CI) of late complications was 2.18 (1.27-3.49) per 100 patient-years of follow-up. Short- and long-term success rates (with 95 %CI) of endoscopic treatment were 97.4 % (94.5 %-100 %) and 94 % (89.6 %-98.3 %), respectively. The peri-PFC recurrence rate was 28 % (20.1 %-35.9 %), and 92.3 % of these occurred within the first 2 years. Stent migration, chronic pancreatitis, and length of stent (> 6 cm) were independently associated with higher rates of peri-PFC recurrence., Conclusions: Long-term transmural drainage with DPS is a safe and effective treatment for DPDS-associated peri-PFCs. However, about one quarter of peri-PFCs will recur., Competing Interests: The authors declare that they have no conflict of interest., (Thieme. All rights reserved.)

ESGE suggests endoscopic therapy and/or extracorporeal shockwave lithotripsy (ESWL) as the first-line therapy for painful uncomplicated chronic pancreatitis (CP) with an obstructed main pancreatic duct (MPD) in the head/body of the pancreas. The clinical response should be evaluated at 6 - 8 weeks; if it appears unsatisfactory, the patient's case should be discussed again in a multidisciplinary team and surgical options should be considered.Weak recommendation, low quality evidence.ESGE suggests, for the selection of patients for initial or continued endoscopic therapy and/or ESWL, taking into consideration predictive factors associated with a good long-term outcome. These include, at initial work-up, absence of MPD stricture, a short disease duration, non-severe pain, absence or cessation of cigarette smoking and of alcohol intake, and, after initial treatment, complete removal of obstructive pancreatic stones and resolution of pancreatic duct stricture with stenting.Weak recommendation, low quality evidence.ESGE recommends ESWL for the clearance of radiopaque obstructive MPD stones larger than 5 mm located in the head/body of the pancreas and endoscopic retrograde cholangiopancreatography (ERCP) for MPD stones that are radiolucent or smaller than 5 mm. Strong recommendation, moderate quality evidence.ESGE suggests restricting the use of endoscopic therapy after ESWL to patients with no spontaneous clearance of pancreatic stones after adequate fragmentation by ESWL.Weak recommendation, moderate quality evidence.ESGE suggests treating painful dominant MPD strictures with a single 10-Fr plastic stent for one uninterrupted year if symptoms improve after initial successful MPD drainage. The stent should be exchanged if necessary, based on symptoms or signs of stent dysfunction at regular pancreas imaging at least every 6 months. ESGE suggests consideration of surgery or multiple side-by-side plastic stents for symptomatic MPD strictures persisting beyond 1 year after the initial single plastic stenting, following multidisciplinary discussion. Weak recommendation, low quality evidence.ESGE recommends endoscopic drainage over percutaneous or surgical treatment for uncomplicated chronic pancreatitis (CP)-related pseudocysts that are within endoscopic reach.Strong recommendation, moderate quality evidence.ESGE recommends retrieval of transmural plastic stents at least 6 weeks after pancreatic pseudocyst regression if MPD disruption has been excluded, and long-term indwelling of transmural double-pigtail plastic stents in patients with disconnected pancreatic duct syndrome.Strong recommendation, low quality evidence.ESGE suggests the temporary insertion of multiple side-by-side plastic stents or of a fully covered self-expandable metal stent (FCSEMS) for treating CP-related benign biliary strictures.Weak recommendation, moderate quality evidence.ESGE recommends maintaining a registry of patients with biliary stents and recalling them for stent removal or exchange.Strong recommendation, low quality evidence., Competing Interests: G.

1:  ESGE suggests using contrast-enhanced computed tomography (CT) as the first-line imaging modality on admission when indicated and up to the 4th week from onset in the absence of contraindications. Magnetic resonance imaging (MRI) may be used instead of CT in patients with contraindications to contrast-enhanced CT, and after the 4th week from onset when invasive intervention is considered because the contents (liquid vs. solid) of pancreatic collections are better characterized by MRI and evaluation of pancreatic duct integrity is possible. Weak recommendation, low quality evidence. 2:  ESGE recommends against routine percutaneous fine needle aspiration (FNA) of (peri)pancreatic collections. Strong recommendation, moderate quality evidence. FNA should be performed only if there is suspicion of infection and clinical/imaging signs are unclear. Weak recommendation, low quality evidence. 3:  ESGE recommends initial goal-directed intravenous fluid therapy with Ringer's lactate (e. g. 5 - 10 mL/kg/h) at onset. Fluid requirements should be patient-tailored and reassessed at frequent intervals. Strong recommendation, moderate quality evidence. 4:  ESGE recommends against antibiotic or probiotic prophylaxis of infectious complications in acute necrotizing pancreatitis. Strong recommendation, high quality evidence. 5:  ESGE recommends invasive intervention for patients with acute necrotizing pancreatitis and clinically suspected or proven infected necrosis. Strong recommendation, low quality evidence.ESGE suggests that the first intervention for infected necrosis should be delayed for 4 weeks if tolerated by the patient. Weak recommendation, low quality evidence. 6:  ESGE recommends performing endoscopic or percutaneous drainage of (suspected) infected walled-off necrosis as the first interventional method, taking into account the location of the walled-off necrosis and local expertise. Strong recommendation, moderate quality evidence. 7:  ESGE suggests that, in the absence of improvement following endoscopic transmural drainage of walled-off necrosis, endoscopic necrosectomy or minimally invasive surgery (if percutaneous drainage has already been performed) is to be preferred over open surgery as the next therapeutic step, taking into account the location of the walled-off necrosis and local expertise. Weak recommendation, low quality evidence. 8:  ESGE recommends long-term indwelling of transluminal plastic stents in patients with disconnected pancreatic duct syndrome. Strong recommendation, low quality evidence. Lumen-apposing metal stents should be retrieved within 4 weeks to avoid stent-related adverse effects.Strong recommendation, low quality evidence., Competing Interests: J.

Background and Study Aims: Paraduodenal pancreatitis is histologically well defined but its epidemiology, natural history, and connection with chronic pancreatitis are not completely understood. The aim of this study was to review the endoscopic and medical management of paraduodenal pancreatitis., Patients and Methods: Medical records of all patients with paraduodenal pancreatitis diagnosed by magnetic resonance cholangiopancreatography (MRCP) or endoscopic ultrasonography (EUS) between 1995 and 2010 were retrospectively reviewed. Clinical features, imaging procedures, and treatments were investigated. The primary end point was the rate of clinical success, and the secondary end points were the radiological or endoscopic improvement, complication rate, and overall survival rate., Results: A total of 51 patients were included in the study (88.2 % alcohol abuse; median age 49 years [range 37 - 70]; 50 men). The most frequent symptoms at presentation were pain (n = 50; 98.0 %) and weight loss (n = 36; 70.6 %). Chronic pancreatitis was present in 36 patients (70.6 %), and 45 patients (88.2 %) had cysts. Other findings included stricture of the pancreatic duct (n = 37; 72.5 %), common bile duct (n = 29; 56.9 %), and duodenum (n = 24; 47.1 %). A total of 39 patients underwent initial endoscopic treatment: cystenterostomy (n = 20), pancreatic and/or biliary duct drainage (n = 19), and/or duodenal dilation (n = 6). For the patients with available follow-up (n = 41), 24 patients required repeat endoscopy and 9 patients required surgery after the initial endoscopic management. After a median follow-up of 54 months (range 6 - 156 months), complete clinical success was achieved in 70.7 % of patients, and the overall survival rate was 94.1 %., Conclusions: This is the largest series concerning the management of paraduodenal pancreatitis using endotherapy as the first-line intervention. Although repeat endoscopic procedures were required in half of the patients, no severe complication was observed and surgical treatment was ultimately needed in less than 25 % of the patients., (© Georg Thieme Verlag KG Stuttgart · New York.)
