Endoscopic treatment of multilocular walled-off pancreatic necrosis with the multiple transluminal gateway technique.

ABSTRACT: The development of minimally invasive techniques allowed access to the necrotic cavity through transperitoneal, retroperitoneal, transmural and transpapillary routes. The choice of access to walled-off pancreatic necrosis (WOPN) should depend not only on the spread of necrosis, but also on the experience of the clinical center. Herein we describe treatment of a patient with multilocular symptomatic walled-off pancreatic necrosis using minimally invasive techniques. The single transmural access (single transluminal gateway technique - SGT) to the necrotic collection of the patient was ineffective. The second gastrocystostomy was performed using the same minimally invasive technique as an extra way of access to the necrosis (multiple transluminal gateway technique - MTGT). In the described case the performance of the new technique consisting in endoscopic multiplexing transmural access (MTGT) was effective enough and led to complete recovery of the patient.

Endoscopic treatment of walled-off pancreatic necrosis complicated with pancreaticocolonic fistula.

Project description:BACKGROUND:Pancreaticocolonic fistulas (PCFs) are serious complication of acute pancreatitis related with high mortality. The aim of this study was to evaluate the efficiency and safety of endoscopic treatment in patients with walled-off pancreatic necrosis (WOPN) complicated with PCF. METHODS:This is a retrospective analysis of results and complications in the group of 226 patients, who underwent endoscopic treatment of symptomatic WOPN between years 2001 and 2016 in the Department of Gastroenterology and Hepatology of Medical University of Gda?sk. RESULTS:PCF was recognized in 21/226 (9.29%) patients. Transmural drainage was performed in 20/21 (95.24%) patients. Transpapillary drainage was used in 2/21 (9.52) patients. The mean time since the start of endotherapy to the diagnosis of a fistulas was 9 (3-21) days. Fluoroscopic nasocystic tube-check imaging of an existing drain was the initial imaging diagnosis of a PCF in 19/21 (90.48%) patients. The mean duration of endoscopic drainage of WOPN was 39.29 (15-87) days. Procedure-related adverse events occurred in 10/21 (47.62%) patients and most of them were treated conservatively. Three patients required surgical treatment. One patient died during endotherapy. The closure of PCF was confirmed via imaging in 17/21 (80.95%) patients. The average time since the recognition till the closure of PCF was 21 (14-48) days. Complete therapeutic success of WOPN complicated with PCF was reached in 16/21 (76.19%) patients. Long-term success of endoscopic treatment was achieved in 15/21 (71.43%) patients. CONCLUSIONS:Endoscopic treatment of patients with WOPN complicated with PCF is an effective method with an acceptable number of complications. The complete regression of the WOPN may lead to spontaneous closure of pancreaticocolonic fistulas.

Clinical impact of EUS treatment of walled-off pancreatic necrosis with dedicated devices.

Project description: Walled-off pancreatic necrosis (WOPN) represents the major risk factor for sepsis-related multiple organ failure. Surgical debridement is an invasive approach associated with high rates of adverse events (AEs) and death. As an alternative, endoscopic ultrasound-guided cysto-gastro-anastomosis has emerged as an effective treatment for WOPNs. Recently a new dedicated-lumen apposing metal stent (LAMS) has been used with satisfactory results in treating peri-pancreatic fluid collections, including WOPNs. The primary outcomes of this study were to evaluate survival and clinical success. Secondary outcomes included: technical success, adverse events and recurrence rate. All consecutive patients with infected WOPN between February 2014 and June 2016 were retrospectively reviewed. Patients underwent placement of a new LAMS incorporated in an electrocautery-enhanced delivery system and direct endoscopic necrosectomy (DEN). DEN was performed immediately after stent deployment and repeated every 3 to 7 days until complete resolution. In the study period we treated 20 consecutive patients with infected WOPN using the new LAMS. Technical success was achieved in 95 % of patients. Clinical success was achieved in 73 % and 84.2 % of patients at 1 and 3 months, respectively. Survival rate was 84.2 % and 79 %. Mean length of hospital stay was 19 days (range 3 - 43). No AEs occurred. Patients were followed up after stent retrieval for a mean time of 554,7 days (range 70 - 986) and no recurrence was observed. DEN following "1-step, exchange-free" LAMS positioning recorded excellent results. We believe that simplicity of procedure plays a key role in terms of safety.

EUS correlates of disconnected pancreatic duct syndrome in walled-off necrosis.

Project description:BACKGROUND AND STUDY AIMS:Although the diagnostic features of disconnected pancreatic duct syndrome (DPDS) by computed tomography (CT) and magnetic/endoscopic retrograde cholangiopancreatography (MRCP/ERCP) have been established, no such characterization exists for endoscopic ultrasound (EUS). This study describes the imaging features of EUS that accurately define DPDS. PATIENTS AND METHODS:This is a prospective study comprising 21 of 42 patients who underwent EUS-guided drainage of walled-off necrosis (WON) over an 18-month period. Findings on EUS were correlated with CT and pancreatography or surgical pathology when available. DPDS by EUS was defined by the presence of a well-defined fluid collection along the course of the main pancreatic duct with the upstream pancreatic parenchyma and duct terminating into the fluid collection. The main outcome measure was to assess the accuracy of EUS in diagnosing DPDS by correlation with CT and pancreatography or surgical pathology. RESULTS:Twenty-one patients with WON (median age 55 years; 15 males) constituted the study cohort. Median duration of pancreatitis was 12 weeks (range 5?-?20) and median WON size was 120?mm (range 40?mm to 200?mm). At EUS, the upstream pancreatic parenchyma and duct were found to terminate within the WON in all 21 patients in whom DPDS was subsequently confirmed by follow-up CT in all patients, by ERCP in 17, EUS-pancreatogram in 3 and surgical pathology in 1.?There was 100?% correlation between EUS characterization of DPDS with CT and pancreatography or surgical pathology. CONCLUSIONS:We report EUS findings indicating the presence of DPDS.?These findings may have significant clinical implications for the management of patients with WON.

Retroperitoneal necrosectomy using lavage circuit as a new technique in the management of pancreatic infected walled off necrosis (WON): A case report.

Project description:IntroductionWalled off necrosis (WON) is clarified according to the revised Atlanta classification, 2013, as a late phase complication of acute necrotizing pancreatitis. Not all cases with WON need intervention but, if indicated both open approach and minimally invasive techniques were clarified. We are discussing here, a case presented to us with infected WON. We adopted the step up approach as the main line of treatment; the case was managed by percutaneous catheter drainage (PCD) followed by retroperitoneal necrosectomy using lavage circuit.Case presentationDiabetic male patient aged 58 year old gave to us with left hypochondrial pain accompanied with easy fatigability and poorly controlled DM. The patient had an attack of acute pancreatitis (AP) 2 months before admission. Abdominal CECT revealed infected WON. The case was managed successfully by retroperitoneal necrozectomy using lavage circuit after failure of PCD.DiscussionA step up approach is followed for determining the optimal interventional strategy for patients presented with infected necrosis. We adopt retroperitoneal debridement using lavage circuit as a 2nd step in this approach. The concept of this technique is to facilitate the detachment of necrotic tissue using the force of saline while minimizing the risk of bleeding.ConclusionInfected WON cases are representing as challenging, we require to get rid of the necrotic material with infected fluid and reduce the hazard of complications. In this technique, we have the advantage of retroperitoneal necrosectomy where we can remove only the loose necrotic tissue by saline force and so, reduce the possible bleeding risk.

Comparative outcomes of endoscopic ultrasound-guided lumen-apposing mental stents drainage for pancreatic pseudocysts and walled-off necrosis: Case series and meta-analysis.

Project description:BackgroundEndoscopic ultrasound (EUS)-guided transmural drainage for pancreatic fluid collections (PFCs) has become the first-line treatment with quicker recovery and more minor injury compared with surgery and percutaneous drainage. The efficacy of stents implantation and drainage for different PFCs remains controversial, especially lumen-apposing metal stents (LAMS). This study aimed to compare the efficacy and safety of LAMS drainage for pancreatic pseudocysts (PPC) and walled-off necrosis (WON).MethodsA meta-analysis was performed for LAMS drainage for WON and PPC by systematically searching PubMed, Cochrane, and Embase databases from January 2010 to January 2020. From 2017 to 2019, 12 patients who were treated with LAMS drainage for PFCs in our medical center were also reviewed and included in this study.ResultsCombining 11 copies of documents with the data from our medical center, a total of 585 patients with PFCs were enrolled in this meta-analysis, including 343 patients with WON and 242 with PPC. The technical success rate in WON is not significantly different from that of PPC (P = 0.08 > 0.05). The clinical success of LAMS placement was achieved in 99% vs 89% in PPC and WON, respectively (RR = 0.92, 95% CI: 0.86-0.98, P = 0.01 < 0.05). The further intervention of direct endoscopic necrosectomy was required by 60% of patients in WON group. There was no significant difference in the incidence of adverse events, including infection, bleeding, stent migration and stent occlusion, after LAMS placement between WON and PPC.ConclusionsEndoscopic ultrasound-guided LAMS for PFCs are feasible, effective with preferable technical and clinical success rates. The clinical effect of LAMS on PPC is slightly better than that of WON, but its adverse reactions still need to be verified in a large-sample prospective study.

Multicenter study of plastic vs. self-expanding metal stents in endoscopic ultrasound-guided drainage of walled-off pancreatic necrosis - PROMETHEUS: a randomized controlled trial protocol.

Project description:BACKGROUND:It seems that lumen-apposing metal stents (LAMS) are displacing plastic stents in the therapy of pancreatic-fluid collection in walled-off necrosis (WON). To date, there is no quality of evidence to recommend LAMS as the standard treatment in the management of WON. The theoretical benefit of LAMS over plastic stents needs to be proven. METHODS/DESIGN:This is a randomized controlled, multicenter, prospective clinical trial with two parallel groups, without masking. One-hundred and fourteen patients with WON will undergo endoscopic ultrasound (EUS)-guided transmural draining in nine tertiary hospitals in Spain and will be randomized to the LAMS or plastic-stent group. The primary endpoint is the short-term (4 weeks) clinical success determined by the reduction of the collection (to < 50% or < 5 cm in size), along with clinical improvement. Secondary endpoints: long-term (4 months) clinical success (total resolution or 5 cm), procedure duration, level of difficulty, safety, and recurrences. DISCUSSION:The PROMETHEUS trial has been designed to determine whether LAMS are superior to plastic stents in EUS-guided transmural drainage of WON.
