Abstract
Numerous lumen-apposing metal stents (LAMS) have been designed for transluminal applications, including complex pancreatic fluid collections (PFCs) and difficult biliary access. Limited high-quality data exist directly comparing the various LAMS models, and their use remains largely dependent on availability and operator expertise. LAMS placement has been streamlined by the addition of electrocautery, allowing for single-step or modified "hot" approach, if desired. Therapeutic endoscopists continue to explore the application of this technology in a variety of clinical scenarios, and future innovations will be needed to meet these evolving clinical demands.

Abstract
BACKGROUND AND STUDY AIMS Pancreatic fluid collection (PFC) is a common complication of pancreatitis for which endoscopic ultrasound-guided drainage is first-line treatment. A new single-device, lumen-apposing, covered self-expanding metal stent (LAMS) has been licensed for PFC drainage. We therefore present our multicenter experience with the LAMS for PFC drainage in a multicenter prospective case series to assess success and complication rates. PATIENTS AND METHODS All adult patients from 11 tertiary centers who had LAMS placement for PFC from July 2015 to July 2016 were included. Data including indications, technical success, clinical success, collection resolution, stent removal, early and late adverse events (AEs), mortality and recurrence at 6 months were collected. RESULTS 116 patients, median age 52.5 years (range 16 - 80) and 67 % male, were treated with a single LAMS in each case. The indication was walled off necrosis (WON) in 70 and pseudocyst in 46. Median size of the PFC was 11 cm (5 - 21 cm) and the estimated median necrotic volume in WON was 30 % (5 % - 90 %). Stent insertion was technically successful in 115 (99.1 %) and clinically successful in 109 (94 %). Early serious AEs (SAEs): n = 7 sepsis, n = 1 stent blockage with food, n = 1 stent migration requiring laparotomy, n = 1 stent dislodgement and n = 1 bleeding requiring emboliZation. Late AEs: n = 1 buried stent and n = 1 esophageal fistula. Non-procedure-related deaths: n = 3 (2.5 %). CONCLUSION This multicenter case series demonstrates that use of the new LAMS is feasible, effective and relatively safe in draining PFC with a technical success rate of 99 % and cumulative SAE rate of 11.2 %.

Efficacy and Safety of Lumen-Apposing Metal Stents in Management of Pancreatic Fluid Collections: Are They Better Than Plastic Stents? A Systematic Review and Meta-Analysis. Dig Dis Sci 2018; 63:289-301. [PMID: 29282638 DOI: 10.1007/s10620-017-4851-0] [Citation(s) in RCA: 69] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2017] [Accepted: 11/14/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND AIMS Endoscopic ultrasound (EUS)-guided transmural drainage has been increasingly utilized as a first-line therapeutic modality for drainage of pancreatic fluid collections (PFC). Recently, lumen-apposing metal stents (LAMS) have been utilized for management of PFCs. We conducted a systematic review and meta-analysis to evaluate the cumulative efficacy and safety of LAMS in the management of PFC (primary outcome). We also compared the efficacy and safety of LAMS with multiple plastic stents (MPS) in the management of PFC (secondary outcome). METHODS We searched Medline, Embase and Cochrane databases from inception to November 5, 2016, to identify studies (with ≥ 10 patients) reporting technical success, clinical success, and adverse events (AE) of EUS-guided transmural drainage of PFC using LAMS. Weighted pooled rates (WPR) were calculated for technical success, clinical success and AE. Risk ratios (RR) were calculated and pooled to compare LAMS with MPS in terms of technical success, clinical success, and AE. Pooled mean difference (MD) was calculated to compare the number of endoscopic sessions required by each type of stent to achieve clinical success. All analyses were done using random effects model. RESULTS Eleven studies with 688 patients were included in this meta-analysis. WPR for technical success of LAMS in PFC management was 98% (96, 99%), (I 2 = 15%). WPR for clinical success was 93% (89, 96%) with moderate heterogeneity (I 2 = 50%). There was no difference in clinical success for pseudocysts (PP) versus walled-off pancreatic necrosis (WON) (P = 0.51). WPR for AE was 13% (9, 20%), (I 2 = 64%). AE were 10% more in WON as compared to PP (P = 0.009). Most common AE requiring intervention was stent migration (4.2%), followed by infection (3.8%), bleeding (2.4%), and stent occlusion (1.9%). Six studies with 504 patients compared the performance of LAMS with MPS. Pooled RR for technical success was 1.71 (0.38, 7.37). Pooled RR for clinical success was 0.37 (0.20, 0.67) in favor of LAMS. Pooled RR for AE was 0.39 (0.18, 0.84), (I 2 = 50%). Pooled MD for number of endoscopic sessions was - 0.84 (- 1.69, 0.01). CONCLUSIONS LAMS seem to have excellent efficacy and safety in the management of PFCs. They may be preferred over plastic stents as they are associated with better clinical success and lesser adverse events.

EUS-guided drainage of peripancreatic fluid collections with lumen-apposing metal stents and plastic double-pigtail stents: comparison of efficacy and adverse event rates. Gastrointest Endosc 2018; 87:150-157. [PMID: 28713067 DOI: 10.1016/j.gie.2017.06.029] [Citation(s) in RCA: 91] [Impact Index Per Article: 15.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2017] [Accepted: 06/20/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Transmural drainage with double-pigtail plastic stents (DPPSs) was the mainstay of endoscopic therapy for symptomatic peripancreatic fluid collections (PPFCs) until the introduction of lumen-apposing covered self-expanding metal stents (LAMSs). Currently, there are limited data regarding the efficacy and adverse event rate of LAMSs compared with DPPSs. METHODS A retrospective analysis of EUS-guided PPFC drainage at a single tertiary care center between 2008 and 2015 was performed. Patients were classified based on drainage method: DPPSs and LAMSs. Adverse event rates, unplanned endoscopic procedures/necrosectomies, and PPFC resolution within 6 months were recorded. Significant bleeding was defined as necessitating transfusion or requiring endoscopic treatment/radiographic embolization. Subsequent endoscopic procedures were defined as unplanned procedures; stent removals were excluded. RESULTS A total of 103 patients met inclusion criteria (84 DPPSs, 19 LAMSs). PPFCs were classified as walled-off necrosis (WON) in 23 (14 DPPSs, 9 LAMSs). There were significantly more bleeding episodes in the LAMS group (4 [19%]: 2 splenic artery pseudo-aneurysms, 1 collateral vessel bleed, 1 intracavitary variceal bleed; P = .0003) than in the DPPS group (1 (1%]: stent erosion into the gastric wall). One perforation occurred in the DPPS group. Unplanned repeat endoscopy was more frequent in the LAMS group (10% vs 26%, P = .07). Among retreated LAMS patients in with WON, 5 (56%) had obstruction by necrotic debris. In patients for whom follow-up was available, 67 of 70 (96%) with DPPSs and 16 of 17 (94%) with LAMSs had resolution of PPFCs within 6 months (P = .78). CONCLUSIONS DPPSs and LAMSs are effective methods for treatment of PPFCs. In our cohort, use of LAMSs was associated with significantly higher rates of procedure-related bleeding and greater need for repeat endoscopic intervention.

Abstract
BACKGROUND AND AIMS Endoscopic transluminal drainage of symptomatic walled-off necrosis (WON) is a good management option, although the optimal choice of drainage site stent is unclear. We performed a systematic review and meta-analysis to compare metal stents (MSs) and plastic stents (PSs) in terms of WON resolution, likelihood of resolution after 1 procedure, and adverse events. METHODS An expert librarian queried several databases to identify studies that assessed WON management, and selection was according to a priori criteria. Publication bias, heterogeneity, and study quality were evaluated with the appropriate tools. We performed single and 2-arm meta-analyses for noncomparative and comparative studies using event rate random-effects model and odds ratio (OR)/difference in means, respectively. RESULTS We included 41 studies involving 2213 patients. In 2-arm study meta-analysis, WON resolution was more likely with MSs compared with PSs (OR, 2.8; 95% confidence interval, 1.7-4.6; P < .001). Resolution with a single endoscopic procedure was similar between stents (47% vs 44%), although for those cases requiring more than 1 intervention, the MS group had fewer interventions, favored by a mean difference of -.9 procedures (95% CI, -1.283 to -.561). In single-arm study meta-analysis, when compared with PSs, MS use was associated with lower bleeding (5.6% vs 12.6%; P = .02), a trend toward lower perforation and stent occlusion (2.8% vs 4.3%, P = .2, and 9.5% vs 17.4%, P = .07), although with higher migration (8.1% vs 5.1%; P = .1). CONCLUSION Evidence suggests that MSs are superior for WON resolution, with fewer bleeding events, trend toward less occlusion and perforation rate, but increased migration rate compared with PSs.

Abstract
BACKGROUND AND AIMS Symptomatic pancreatic walled-off necrosis (WON) may be managed by endoscopic transmural drainage and endoscopic transmural necrosectomy, with stent placement at endoscopic drainage sites. The optimal stent choice is yet to be determined. We compared outcomes after endoscopic management of WON using either large-caliber fully covered self-expandable metal stents (LC-SEMSs) or double-pigtail plastic stents (DPPSs). METHODS We performed a retrospective comparison of outcomes among patients who received LC-SEMSs or DPPSs before endoscopic transmural necrosectomy for WON. RESULTS Among 94 patients included, WON resolution rates did not differ between the DPPS (36 patients) and LC-SEMS (58 patients) groups, whether concomitant percutaneous drainage was considered a failure (75% vs 82.8%; P = .36) or not (91.7% vs 94.8%; P = .55). Of 75 patients (80%) successfully treated without percutaneous drainage, 37 (49%) underwent endoscopic transmural drainage without subsequent endoscopic transmural necrosectomy. WON was more likely to resolve without subsequent endoscopic transmural necrosectomy in the LC-SEMS group than the DPPS group (60.4% vs 30.8%; P = .01). WON resolution without subsequent endoscopic transmural necrosectomy remained more likely with LC-SEMSs (odds ratio, 4.5 [95% confidence interval, 1.5-15.5]) after adjusting for patient age and size and location of WON. Rates of adverse events were similar except for clinically significant bleeding requiring endoscopic intervention, which was higher with DPPSs than LC-SEMSs (14% vs 2%; P = .02). CONCLUSION Management of pancreatic WON with LC-SEMSs appears to decrease both the need for repeated necrosectomy procedures and the risk of intervention-related hemorrhage.

A comparison of outcomes between a lumen-apposing metal stent with electrocautery-enhanced delivery system and a bi-flanged metal stent for drainage of walled-off pancreatic necrosis. Endosc Int Open 2017; 5:E1189-E1196.

Abstract
BACKGROUND AND STUDY AIMS Bi-flanged metal stents (BFMS) have shown promise in the drainage of walled-off pancreatic necrosis (WON), but their placement requires multiple steps and the use of other devices. More recently, a novel device consisting of a combined lumen-apposing metal stent (LAMS) and electrocautery-enhanced delivery system has been introduced. The aim of this study was to compare the placement and outcomes of the two devices. PATIENTS AND METHODS This was a retrospective review of consecutive patients undergoing endoscopic ultrasound-guided placement of BFMS or LAMS for drainage of symptomatic WON. Data from procedures between October 2012 and December 2016 were taken from a prospectively maintained database. We compared technical and clinical success, procedure time, costs, and composite end point of significant events (adverse events, stent migration, additional percutaneous drainage) between BFMS and LAMS. RESULTS 72 consecutive patients underwent placement of BFMS (40 patients, 44 stents) or LAMS (32 patients, 33 stents). Technical success was 91 % for BFMS and 97 % for LAMS. Clinical success was 65 % vs. 78 %, respectively. Median in-room procedure time was significantly shorter in the LAMS group (45 minutes [range 30 - 80]) than in the BFMS group (62.5 minutes [range 35 - 135]; P < 0.001) and fewer direct endoscopic necrosectomies (DEN) were performed (median 1 [0 - 2.0] vs. 2 [0 - 3.7], respectively; P = 0.005). If only inpatients were considered (35 BFMS and 19 LAMS), there was no significant difference in DEN 2 (range 0 - 11) and 2 (range 0 - 8), respectively. The composite end point of 32 % vs. 24 % was not significantly different. Median procedural costs for all patients with successful stent placement for WON treatment was €4427 (range 1630 - 12 926) for BFMS vs. €3500 (range 2509 - 13 393) for LAMS ( P = 0.10). CONCLUSION LAMS was superior to BFMS in terms of procedure time, with comparable adverse events, success, and costs.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic ultrasound-guided drainage of symptomatic walled-off pancreatic necrosis (WON) usually has been performed with double pigtail plastic stents (DPS) and more recently, with lumen-apposing metal stents (LAMS). However, LAMS are significantly more expensive and there are no comparative studies with DPS. Accordingly, we compared our experience with combined endoscopic and percutaneous drainage (dual-modality drainage [DMD]) for symptomatic WON using LAMS versus DPS. PATIENTS AND METHODS Patients who underwent DMD of WON between July 2011 and June 2016 using LAMS were compared with a matched group treated with DPS. Technical success, clinical success, need for reintervention and adverse events (AE) were recorded. RESULTS A total of 50 patients (31 males, 25 patients treated with LAMS and 25 patients treated with DPS) were matched for age, sex, computed tomography severity index, and disconnected pancreatic ducts. Technical success was achieved in all patients. Mean days hospitalized post-intervention (14.5 vs. 13.1, P = 0.72), time to resolution of WON (77 days vs. 63 days, P = 0.57) and mean follow-up (207 days vs. 258 days, P = 0.34) were comparable in both groups. AEs were similar in both groups (6 vs. 8, P = 0.53). Patients treated with LAMS had significantly more reinterventions per patient (1.5 vs. 0.72, P = 0.01). CONCLUSIONS In treatment of symptomatic WON using DMD, LAMS did not shorten time to percutaneous drain removal and was not associated with fewer AEs.

Abstract
For patients recovering from acute pancreatitis, the development of a pancreatic fluid collection (PFC) predicts a more complex course of recovery, and introduces difficult management decisions with regard to when, whether, and how the collection should be drained. Most PFCs resolve spontaneously and drainage is indicated only in pseudocysts and walled-off pancreatic necrosis when the collections are causing symptoms and/or local complications such as biliary obstruction. Historical approaches to PFC drainage have included surgical (open or laparoscopic cystgastrostomy or pancreatic debridement), and the placement of percutaneous drains. Endoscopic drainage techniques have emerged in the last several years as the preferred approach for most patients, when local expertise is available. Lumen-apposing metal stents (LAMS) have recently been developed as a tool to facilitate potentially safer and easier endoscopic drainage of pancreatic fluid collections, and less commonly, for other indications, such as gallbladder drainage. Physicians considering LAMS placement must be aware of the complications most commonly associated with LAMS including bleeding, migration, buried stent, stent occlusion, and perforation. Because of the patient complexity associated with severe pancreatitis, management of pancreatic fluid collections can be a complex and multidisciplinary endeavor. Successful and safe use of LAMS for patients with pancreatic fluid collections requires that the endoscopist have a full understanding of the potential complications of LAMS techniques, including how to recognize and manage expected complications.

Abstract
BACKGROUND AND AIMS Endoscopic ultrasound (EUS) guided drainage of symptomatic pancreatic walled-off necrosis (WON) followed by fully covered self-expanding metal stent (FCSEMS) placement offers several advantages such as higher technical success rate and the option of necrosectomy. The aim of this study was to evaluate the safety and efficacy of EUS guided drainage of patients with WON by using FCSEMS and intracavitary lavage with a solution containing hydrogen peroxide and adopting a step-up approach. METHODS A prospective open label study was carried out at a single tertiary care center between January 2014 and January 2016. Patients with symptomatic WON who underwent EUS guided drainage followed by FCSEMS placement were included. Primary end points were complete drainage with improvement in symptoms or major adverse events. Secondary end points were minor adverse events related to the procedures. RESULTS A total of 64 patients (mean age 36 years; 52 males) were included. Technical success was achieved in 100 % of patients and clinical success was achieved in 90.6 %. Complete drainage was achieved with FCSEMS alone in 18 (28.1 %), FCSEMS with necrosectomy using lavage in 40 (62.5 %), FCSEMS with percutaneous drainage (PCD) in 5 (7.8 %), and 1 (1.6 %) patient required salvage surgery. The major adverse event was life threatening bleeding in 3 (4.7 %) patients. Minor adverse events were non-life threatening bleeding in 2 (3.1 %) patients and stent migration in 3 (4.7 %) patients. CONCLUSION EUS guided WON drainage with FCSEMS followed by necrosectomy with lavage using a solution containing hydrogen peroxide as a step-up approach is a minimally invasive and effective method with a high technical and clinical success rate. Patients with solid debris > 40 % need aggressive management.

Abstract
BACKGROUND AND STUDY AIMS 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. PATIENTS AND METHODS 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. RESULTS 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. CONCLUSIONS 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.

Efficacy and safety of metallic stents in comparison to plastic stents for endoscopic drainage of peripancreatic fluid collections: a meta-analysis and trial sequential analysis. Clin J Gastroenterol 2017; 10:403-414. [PMID: 28721541 DOI: 10.1007/s12328-017-0763-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2017] [Accepted: 07/10/2017] [Indexed: 12/21/2022]
Abstract
Metallic stents are being increasingly used for endoscopic drainage of peripancreatic fluid collections (PFCs) but their superiority over plastic stents has not been proven. We carried out a meta-analysis to consolidate the results from available studies and to suggest evidence-based recommendations. Studies that compared plastic and metallic stents for endoscopic drainage of PFCs and published before October 2016 were searched. Comparisons were performed for clinical success, adverse events, salvage interventions, mortality, technical success and recurrence. We included six studies with 856 patients (479 in the metallic stent group and 377 in the plastic stent group). The clinical success rate was significantly higher with metallic stents than with plastic stents (Mantel-Haenszel odds ratio [MH-OR] 3.22; 95% CI 1.87-5.54; P < 0.001). The rate of adverse events (MH-OR 0.40; 95% CI 0.24-0.65; P < 0.001) and the need for salvage procedures (MH-OR 0.31; 95% CI 0.13-0.70; P = 0.01) were also significantly lower with the use of metallic stents. Subgroup analysis for the type of PFC also found better results with the metallic stents. The results of Egger's regression test (X-axis intercept at -0.63, P = 0.47) and funnel plot did not suggest any significant publication bias. We conclude that compared to plastic stents, the use of metallic stents for endoscopic drainage of PFCs is associated with significantly better clinical success and significantly lower rates of adverse events and the need for salvage procedures. However, further high-quality randomized trials are required to confirm these findings.

Abstract
BACKGROUND AND AIMS EUS-guided transluminal drainage (EUS-TD) and sequential direct endoscopic necrosectomy (DEN) for pancreatic fluid collections (PFCs) by using a dedicated biflanged metal stent (BFMS) has been reported as a useful alternative to using plastic stents or a conventional metal stent. However, current dedicated BFMSs have limitations. Recently, a new BFMS with solidly constructed biflanges and various stent lengths matched to the PFC condition has been developed. Herein, we prospectively evaluated this new BFMS for the treatment of PFCs. METHODS From July 2015 to July 2016, EUS-TD by using the new BFMS was performed in 12 patients for PFCs (4 patients with pancreatic pseudocysts, 8 patients with walled-off necrosis). When clinical resolution could not be achieved, DEN was performed the following day. RESULTS The stent was deployed successfully with a median procedure time of 16 minutes (range 11-24 minutes) and with no procedure-related adverse events in any patients (12/12, 100%). DEN via the stent was achieved in all patients in whom they were attempted (4/4,100%). Spontaneous stent migration or stent dislocation during DEN was not observed in any patients. Two WON patients died from spontaneous pseudoaneurysm rupture and multiple organ failure. The PFCs in the other 10 patients completely resolved, and later the stent was removed with no difficulty in 9 patients after a median time of 48 days (range 30-180 days). CONCLUSIONS The new BFMS is technically feasible and safe for the treatment of PFCs. (Clinical trial registration number: UMIN000021347.).

Abstract
BACKGROUND AND AIMS EUS-guided drainage using plastic stents may be inadequate for treatment of walled-off necrosis (WON). Recent studies report variable outcomes even when using covered metal stents. The aim of this study was to evaluate the efficacy of a dedicated covered biflanged metal stent (BFMS) when adopting an endoscopic "step-up approach" for drainage of symptomatic WON. METHODS We retrospectively evaluated consecutive patients with symptomatic WON who underwent EUS-guided drainage using BFMSs over a 3-year period. Reassessment was done between 48 and 72 hours for resolution. Endoscopic reinterventions were tailored in nonresponders in a stepwise manner. Step 1 encompassed declogging the blocked lumen of the BFMS. In step 2, a nasocystic tube was placed via BFMSs with intermittent irrigation. Step 3 involved direct endoscopic necrosectomy (DEN). BFMSs were removed between 4 and 8 weeks of follow-up. The main outcome measures were technical success, clinical success, adverse events, and need for DEN. RESULTS Two hundred five WON patients underwent EUS-guided drainage using BFMSs. Technical success was achieved in 203 patients (99%). Periprocedure adverse events occurred in 8 patients (bleeding in 6, perforation in 2). Clinical success with BFMSs alone was seen in 153 patients (74.6%). Reintervention adopting the step-up approach was required in 49 patients (23.9%). Incremental success was achieved in 10 patients with step 1, 16 patients with step 2, and 19 patients with step 3. Overall clinical success was achieved in 198 patients (96.5%), with DEN required in 9.2%. Four patients failed treatment and required surgery (2) or percutaneous drainage (2). CONCLUSIONS The endoscopic step-up approach using BFMSs was safe, effective, and yielded successful outcomes in most patients, reducing the need for DEN.

Abstract
Endoscopic ultrasound (EUS)-guided drainage is now firmly established as the best option for drainage of walled-off pancreatic fluid collections (PFC). It has high clinical efficacy, similar to surgical and percutaneous approaches, but with lower morbidity and costs. It is superior to non-EUS-guided approaches because even collections without endoluminal bulging can be successfully drained. Transmural drainage alone is sufficient for pseudocysts, but in the context of walled-off pancreatic necrosis (WON), adjunctive direct endoscopic necrosectomy (DEN) may be required. Traditionally, double pigtail plastic stents (PS) were used for transmural drainage, but, recently, fully covered self-expandable metallic stents (FCSEMS) customized for PFC drainage have become available and are increasingly used, especially in the management of WON, because the larger-diameter stent facilitates drainage and insertion of an endoscope into the WON cavity for DEN. The present review will discuss the evidence for EUS-guided drainage and DEN, the technical problems involved, and the roles of PS and FCSEMS in PFC drainage.

Abstract
The development of pancreatic fluid collections (PFC) is one of the most common complications of acute severe pancreatitis. Most of the acute pancreatic fluid collections resolve and do not require endoscopic drainage. However, a substantial proportion of acute necrotic collections get walled off and may require drainage. Endoscopic drainage of PFC is now the preferred mode of drainage due to reduced morbidity and mortality as compared to surgical or percutaneous drainage. With the introduction of new metal stents, the efficiency of endoscopic drainage has improved and the task of direct endoscopic necrosectomy has become easier. The requirement of re-intervention is less with new metal stents as compared to plastic stents. However, endoscopic drainage is not free of adverse events. Severe complications including bleeding, perforation, sepsis and embolism have been described with endoscopic approach to PFC. Therefore, the endoscopic management of PFC is a multidisciplinary affair and involves interventional radiologists as well as GI surgeons to deal with unplanned adverse events and failures. In this review we discuss the recent advances and controversies in the endoscopic management of PFC.

Abstract
OBJECTIVES Endoscopic ultrasound (EUS)-guided drainage with fully covered self-expanding metallic stents (FCSEMS) has been successfully used in adult patients. The utility of FCSEMS in children with walled-off necrosis (WON) is, however, unknown. The aim of present study was to evaluate the feasibility, safety, and efficacy of EUS drainage of WON using FCSEMS in children. METHODS We retrospectively evaluated the data of children (18 years or younger) who underwent EUS drainage of WON using FCSEMS at our institution. All FCSEMS were removed between 1 and 3 months. Feasibility, safety, and efficacy were analysed. RESULTS Twenty-one children (20 boys, mean age 14.9 ± 2.34 years, range 9-18 years) underwent EUS-guided drainage of WON with FCSEMS. The median size of WON was 88 mm (55-148 mm). The median interval between onset of acute pancreatitis and EUS guided drainage was 58 days (range 30-288 days). The technical and clinical success rates were 100% and 95%, respectively. Nasocystic tube was placed in 3 children for lavage. Endoscopic necrosectomy was not required in any of the children. There were no major complications. Minor complications included bleeding (2), stent migration (1), and difficulty in removal of stent (1). After a median follow-up of 360 days (range: 30-1020 days), there was 1 recurrence of WON. CONCLUSIONS EUS drainage of WON using specially designed FCSEMS is safe and efficacious in children. The utility of FCSEMS in children should be further explored and compared with plastic stents.

Abstract
Endoscopic ultrasound (EUS)-guided fine-needle aspiration (EUS-FNA) is highly accurate in obtaining specific diagnoses for various diseases. The present study aimed to evaluate the diagnostic yields, accuracies and sampling adequacies, of slow-pull, 5 ml suction and 10 ml suction techniques in EUS-FNA of solid lesions. The present study was a retrospective comparative study, which was performed in tertiary academic centers, recognized for their expertise in EUS and EUS-guided FNA. The present study involved 149 patients who underwent EUS-FNA of solid masses. A total of 34 (22.8%), 37 (24.8%) and 78 (52.4%) patients underwent EUS-FNA with slow-pull, 5 ml suction and 10 ml suction techniques, respectively. The EUS-FNA cytology and histology results were compared with those from the gold standard of surgical histopathology [hematoxylin-eosin staining; immunohistochemical test of cluster of differentiation (CD) 79a, CD20 and flow cytometry test] or long-term clinical follow-up. The present retrospective comparative study demonstrated that the diagnostic yields and accuracies of EUS-FNA with slow-pull (86.1%) were significantly superior to those achieved with 5 ml suction (83.3%) or 10 ml suction (69.9%; P<0.0001; χ2 test). Consistently, 86.5% (32/37) of the samples obtained from the 5 ml suction group were adequate for histological diagnosis. By contrast, 70.6 (24/34) and 85.9% (67/78) of samples from the slow-pull and 10 ml suction groups were adequate for histological diagnosis, respectively. The samples obtained using 10 ml suction contained more blood compared with those obtained via slow-pull and 5 ml suction (P=0.0056; χ2 test). No complications were noted in any of the three groups. The samples that were obtained for histopathological diagnosis using 5 ml suction were superior to those obtained using slow-pull or 10 ml suction. Additional multi-central prospective studies in which EUS-FNA is performed with variable negative pressures are required to improve the defining of the diagnostic roles of those techniques.

Abstract
BACKGROUND AND STUDY AIM The commonly used minimally invasive methods for patients with infected pancreatic necrosis (IPN) are initial endoscopic transluminal drainage (ETD) and percutaneous catheter drainage (PCD), which are followed, if necessary, by endoscopic or surgical necrosectomy. This study intends to explore which of the two minimally invasive treatments leads to a better prognosis. PATIENTS AND METHODS Patients with IPN and an indication for intervention were prospectively enrolled and underwent either initial ETD or PCD followed, if necessary, by endoscopic or surgical necrosectomy. RESULTS Initial treatment success occurred in 8 of 11 patients after ETD (72.7%) and in 3 of 13 patients after PCD (30.8%) (risk ratio [RR] with ETD, 2.36; 95% CI 0.97-5.77; P = 0.04). After 1 year of follow-up, 72.7% of patients survived with ETD, and 69.2% survived with PCD (RR 1.05; 95% CI 0.63-1.75; P = 0.85). Intestinal fistula seems to have occurred less in the patients who received initial ETD rather than PCD therapy (9.1 vs. 38.5%; RR 0.24; 95% CI 0.03-1.73; P = 0.098). Fewer patients who underwent an initial ETD were transferred to surgery (9.1 vs. 46.2%; RR 0.20; 95% CI 0.03-1.40; P = 0.047). A higher rate of new-onset diabetes (3 cases) or impaired glucose tolerance (1 case) occurred in initial PCD compared to ETD (40 vs. 0%, P = 0.042). CONCLUSION The outcomes of initial endoscopic transluminal drainage are superior to percutaneous drainage for patients with infected pancreatic necrosis (ChiCTR-ONRC-13003653).

Abstract
Background Recently, a novel lumen-apposing fully covered self-expanding metal stent (LA-FCSEMS) mounted on an electrocautery-enhanced delivery system has been developed to perform endoscopic ultrasound (EUS)-guided transluminal drainage. From early experience, however, release of the proximal flange of the stent has mostly been done using endoscopic view guidance to ensure proper positioning. Aim We describe a new technique that we have named the Intra-Channel Stent Release Technique (ICSRT) to perform stent placement under complete EUS control, without the use of either fluoroscopic or endoscopic views. Material and methods Data on all consecutive patients who underwent EUS-guided drainage using the new ICSRT between June 2014 and April 2016 were retrospectively retrieved from two institution databases. All EUS procedures were performed by experienced endoscopists with the patient under conscious or deep sedation. The total procedure and stent deployment time, and adverse events related to stent positioning with the ICSRT were evaluated. Results One hundred consecutive patients (51 women; mean age ± SD, 66 ± 15.2 years, range 34 - 95) underwent EUS-guided transluminal drainage with the Hot AXIOS™ device using the new ICSRT. The procedure was technically successful in all but one patient (1 %). The mean total procedural time was 21.9 minutes (range 7 - 50), while the mean time for stent placement was 3.2 minutes (range 1 - 15). No major adverse events occurred. Discussion The ICSRT has been used to deploy the newly developed lumen-apposing FCSEMS under complete EUS guidance without fluoroscopic and/or endoscopic assistance. The technique appears to be safe and highly effective and should be learned by all interventional endosonographers in order to be able to perform drainage in all clinical scenarios.

Endoscopic ultrasonography-guided transmural drainage of walled-off pancreatic necrosis: Comparison between a specially designed fully covered bi-flanged metal stent and multiple plastic stents. Dig Endosc 2017; 29:104-110.

Abstract
BACKGROUND AND AIM Endoscopic ultrasonography (EUS)-guided drainage of walled-off necrosis (WON) may be carried out by placement of multiple plastic stents (MPS) or specially designed fully covered bi-flanged metal stents (BFMS). Comparative data on efficacy of these two stent types for WON drainage are limited. This retrospective study compares outcomes of WON drainage using BFMS and MPS. METHODS During a 10-year period, 133 patients underwent EUS-guided WON drainage. MPS or BFMS were placed in a WON cavity through a single puncture, and direct endoscopic necrosectomy (DEN) was carried out whenever clinically necessary. Data in the two cohorts were retrospectively compared for primary outcomes - clinical success, adverse events and mortality; and secondary outcomes - DEN requirement, mean DEN sessions, need for salvage surgery and hospital stay. RESULTS MPS were placed in 61 and BFMS in 72 patients. Patients undergoing BFMS drainage required fewer DEN sessions (mean 1.46 vs 2.74, P < 0.05), had fewer adverse events (5.6% vs 36.1%, P < 0.05), needed salvage surgery less often (2.7% vs 26.2%, P < 0.05), and had significantly shorter hospital stay (4.1 vs 8 days, P < 0.05) compared to those undergoing MPS drainage. There was no difference in DEN requirement (P = 0.217) and mortality (P = 0.5) in both groups. Overall clinical success with BFMS was superior to MPS (94% vs 73.7%, P < 0.05). CONCLUSION BFMS appear to be superior to MPS for EUS-guided WON drainage in terms of clinical success, number of DEN sessions, adverse events, need for salvage surgery and hospital stay.

Abstract
BACKGROUND Endoscopic ultrasonography-guided drainage has been established as a good treatment modality in the management of walled-off pancreatic necrosis, but the unmanageable infection of postoperation is still a thorny problem due to the poor drainage ability for solid necrotic debris only through transmural stent and nasocystic catheter. AIMS Introduce a novel therapeutic method, namely endoscopic ultrasonography-guided drainage combined with cyclic irrigation technique in managing patients with walled-off pancreatic necrosis. METHODS 18 patients with severe acute pancreatitis complicated with walled-off pancreatic necrosis received treatment with endoscopic ultrasonography-guided drainage combined with cyclic irrigation were involved in this retrospective study. RESULTS 17 of 18 patients with walled-off pancreatic necrosis were treated by this new therapeutic method. Subsequent surgery was performed in 1 case due to uncontrolled infection, complications such as perforation, bleeding or multiple organ failure were not observed. Treatment success rate was high (16 in 17, 94.12%). CONCLUSION Endoscopic ultrasonography-guided drainage combined with cyclic irrigation is an effective treatment option for symptomatic walled-off pancreatic necrosis to facilitate drainage and obviate the need for subsequent surgery or endoscopic necrosectomy.

Abstract
BACKGROUND & AIMS Endoscopic ultrasound-guided transmural drainage and necrosectomy have become the standard treatment for patients with pancreatic walled-off necrosis (WON). Lumen-apposing metal stents (LAMS) have shown success in the management of pancreatic fluid collections. However, there are few data on their specific roles in management of WON. We investigated the efficacy and safety of LAMS in treatment of WON. METHODS We performed a retrospective multicenter case series of 124 patients with WON who underwent endoscopic transmural drainage by using LAMS at 17 tertiary care centers from January 2014 through May 2015. Patients underwent endoscopic ultrasound-guided cystogastrostomy or cystoenterostomy with placement of an LAMS into the WON collection. At the discretion of the endoscopist, we performed direct endoscopic necrosectomy, irrigation with hydrogen peroxide, and/or nasocystic drain placement. We performed endoscopic retrograde cholangiopancreatography with pancreatic duct stent placement when indicated. Concomitant therapies included direct endoscopic debridement (n = 78), pancreatic duct stent placement for leak (n = 19), hydrogen peroxide-assisted necrosectomy (n = 38), and nasocystic irrigation (n = 22). We collected data for a median time of 4 months (range, 1-34 months) after the LAMS placement. The primary outcomes were rates of technical success (successful placement of the LAMS), clinical success (resolution of WON, on the basis of image analysis, without need for further intervention via surgery or interventional radiology), and adverse events. RESULTS The median size of the WON was 9.5 cm (range, 4-30 cm). Eight patients had 2 LAMS placed for multiport access, all with technical success (100%). Clinical success was achieved in 107 patients (86.3%) after 3 months of follow-up. Thirteen patients required a percutaneous drain, and 3 required a surgical intervention to manage their WON. The stents remained patent in 94% of patients (117 of 124) and migrated in 5.6% of patients (7 of 124). The median number of endoscopic interventions was 2 (range, 1-9 interventions). CONCLUSIONS On the basis of a retrospective analysis of 124 patients, endoscopic therapy of WON by using LAMS is safe and effective. Creation of a large and sustained cystogastrostomy or cystoenterostomy tract is effective in the drainage and treatment of WON.

Abstract
Endoscopic Ultrasound (EUS) provides the unique opportunity to visualize, interrogate and intervene gastrointestinal (GI) luminal, mural or peri-luminal structures and pathology with negligible adverse effects. Diagnostic, upper GI and rectal EUS is feasible, extremely safe, and efficacious. Most EUS guided interventions are safe, effective and minimally invasive, compared to peers in the percutaneous radiological or surgical procedures. As with any endoscopic procedure, EUS and its guided interventions may be accompanied by adverse events. EUS related complications are generally infrequent in expert hands, and mainly include bleeding and perforation. However, the nature and severity of adverse events associated with each EUS guided procedure are unique. Hence, it is paramount for endosonographer to have sufficient knowledge of the indications, techniques, and potential risks involved before contemplating any given procedure. Most common intervention with EUS is transmural fine needle aspiration (FNA), which is an extremely safe procedure. EUS guided drainage procedures are rapidly evolving with newer devices and methods being employed. Among them, EUS guided drainage of pancreatic fluid collection-pseudocyst or walled off necrosis (WON), has largely replaced other methods (surgical, percutaneous or non-EUS endoscopic) with acceptable complications. Currently, dedicated metal stents are more widely used compared to plastic stents for drainage of PFC, especially WON. EUS has made a definite impact in biliary access and drainage of obstructed biliary system, in patients where ERCP has failed or is technically not possible, closely competing with percutaneous biliary drainage. In spite of some complications, recent improvement in devices for bilio-enteric fistula creation and stent designs, has added to its safety and efficacy. EUS guided pancreatic duct drainage remains the most challenging of EUS guided interventions where in-roads are being made.

Abstract
Walled-off necrosis (WON) is a new term for encapsulated necrotic tissue after severe acute pancreatitis. Various terminologies such as pseudocyst, necroma, pancreatic abscess, and infected necrosis were previously used in the literature, resulting in confusion. The current and past terminologies must be reconciled to meaningfully interpret past data. Recently, endoscopic necrosectomy was introduced as a treatment option and is now preferred over surgical necrosectomy when the expertise is available. However, high-quality evidence is still lacking, and there is no standard management strategy for WON. The consensus meeting aimed to clarify the diagnostic criteria for WON and the role of endoscopic interventions in its management. In the Consensus Conference, 27 experts from eight Asian countries took an active role and examined key clinical aspects of WON diagnosis and endoscopic management. Statements were crafted based on literature review and expert opinion, employing the modified Delphi method. All statements were substantiated by the level of evidence and the strength of the recommendation. We created 27 consensus statements for WON diagnosis and management, including details of endoscopic procedures. When there was not enough solid evidence to support the statements, this was clearly acknowledged to facilitate future research. Proposed management strategies were formulated and are illustrated using flow charts. These recommendations, which are based on the best current scientific evidence and expert opinion, will be useful for guiding endoscopic management of WON. Part 2 of this statement focused on the endoscopic management of WON.

Abstract
INTRODUCTION Endoscopic ultrasound guided translumenal drainage of pancreatic fluid collections (PFCs) has been widely practiced for over a decade, using conventional plastic and self-expandable metal stents. The use of such stents for transmural drainage is off-label and limited by the lack of lumen-to-lumen anchorage, which can lead to leakage, migration and tissue trauma. AREAS COVERED Novel stent designs dedicated to applications of translumenal drainage have recently emerged and promise to make transmural drainage quicker, safer, and more effective. Achieving faster resolution of the fluid collection, decreasing adverse events, decreasing recurrence rates, and lowering costs are critical to advancing the endoscopic management of PFCs. Expert commentary: Our paper suggests that the AXIOS stent is an innovative therapeutic approach for PFC drainage with excellent efficacy, safety, and relatively few adverse outcomes. Preliminary reports appear promising and large multicenter prospective studies are needed in the future to further determine its safety and efficacy.

Abstract
BACKGROUND AND AIMS EUS-guided drainage of peripancreatic fluid collection (PFC) (pancreatic pseudocyst [PP] or walled-off necrosis [WON]) by using a novel lumen-apposing, fully covered, self-expandable metal stent (LAMS) has been promising, but few of these data are from the United States. The aim of this study was to evaluate clinical outcomes and safety of EUS-guided drainage of pancreatic pseudocysts and WON by using the LAMS. METHODS We conducted a multicenter, retrospective study on 82 patients with symptomatic PFC who underwent EUS-guided drainage by using the LAMS at 4 U.S. tertiary care centers. Outcomes evaluated included successful placement of the LAMS, the number of patients in whom complete resolution of PPs or WON was achieved, the number of procedures performed per patient to achieve PFC resolution, and adverse events. RESULTS The mean size of the PFC was 11.8 cm. LAMSs were successfully placed in 80 patients (97.5%). Twelve patients had PP and 68 had WON. The median stent in-dwelling time was 2 months (range 1-3 months). Endoscopic debridement with the LAMS in WON was performed in 54 patients. The patency of the stent was maintained in 98.7% of the patients (77/78). There was spontaneous dislodgment of 2 LAMSs. Successful endoscopic therapy by using the LAMS was successful in 12 of 12 patients (100%) with PP compared with 60 of 68 patients (88.2%) with WON. All stents were endoscopically removed from all patients after peripancreatic fluid collection (PFC) resolution. There was 1 PFC recurrence during the 3-month median follow-up period. Procedure-related adverse events occurred in 8 patients (9.8%), and included stent maldeployment (n = 2), and self-limited bleeding (n = 6). In 1 patient with stent maldeployment gastric perforation developed, and the patient underwent surgical repair. CONCLUSION EUS-guided drainage of PFCs by using the novel LAMS has high technical and long-term success rates. Due to its ease of use, the LAMSs may simplify and streamline EUS-guided management of PFCs, particularly for the endoscopic debridement of WON, and may help in its widespread adoption as an alternative to surgery.

Abstract
Innovations in stent technology and technological advances in endoscopic ultrasonography have led to rapid expansion of their use in the field of gastrointestinal diseases. In particular, endoscopic ultrasonography-guided metal stent insertion has been used for the management of pancreatic fluid collection, bile duct drainage, gallbladder decompression, and gastric bypass. Endoscopic ultrasonography-guided drainage of intra-abdominal fluid collections using a plastic or metal stent is well established. Because of the various limitations—such as stent migration, injury and bleeding in the lumen—recently developed, fully covered self-expanding metal stents or lumen-apposing metal stents have been introduced for those fluids management. This article reviews the recent literature on newly developed endoscopic ultrasonography-guided metal stents and the efficacy thereof.

A two-center comparative study of plastic and lumen-apposing large diameter self-expandable metallic stents in endoscopic ultrasound-guided drainage of pancreatic fluid collections. Endosc Ultrasound 2016; 5:320-327. [PMID: 27803905 PMCID: PMC5070290 DOI: 10.4103/2303-9027.191659] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/06/2023] Open
Abstract
Background and Objectives: Endoscopic ultrasound-guided drainage of walled-off pancreatic fluid collections (PFCs) (pseudocyst [PC]; walled-off necrosis [WON]) utilizes double pigtail plastic stents (PS) and the newer large diameter fully covered self-expandable stents (FCSEMS) customized for PFC drainage. This study examined the impact of type of stent on clinical outcomes and costs. Patients and Methods: Retrospective two-center study. Outcome variables were technical and clinical success, need for repeat procedures, need for direct endoscopic necrosectomy (DEN), and procedure-related costs. Results: A total of 49 (PC: 31, WON: 18) patients were analyzed. Initially, PS was used in 37 and FCSEMS in 12. Repeat transmural drainage was required in 14 (PS: 13 [9 treated with PS, 4 treated with FCSEMS]; FCSEMS: 1 [treated with PS]) due to stent migration (PS: 3; FCSEMS: 1) or inadequate drainage (PS: 10). Technical success was 100%. Initial clinical success was 64.9% (25/38) for PS versus 91.7% (11/12) for FCSEMS (P = 0.074). With repeat transmural stenting, final clinical success was achieved in 94.6% and 100%, respectively (P = 0.411). Compared to FCSEMS, PS was associated with greater need for repeat drainage (34.2% vs. 6.3%, P = 0.032). The need for and frequency of DEN was similar between both groups, but PS required more frequent balloon dilatation. PS was significantly cheaper for noninfected PC. Costs were similar for infected PC and WON. Conclusion: PS was associated with a higher need for a second drainage procedure to achieve clinical success. The use of FCSEMS did not increase procedural costs for infected PC and WON.

Abstract
BACKGROUND AND AIMS A lumen-apposing, self-expanding metal stent incorporated in an electrocautery-enhanced delivery system for EUS-guided drainage of pancreatic fluid collections (PFCs) recently has become available. The aim of this study was to analyze the safety and clinical effectiveness of this newly developed device in this clinical setting. METHODS This was a retrospective analysis of all consecutive patients with PFCs who underwent EUS-guided drainage using the study device in 13 European centers. RESULTS Ninety-three patients with PFCs (80% with complex collections) underwent drainage using the study device. Penetration of the PFC was accomplished directly with the study device in 74.2% of patients, and successful stent placement was accomplished in all but 1 patient, mostly without fluoroscopic assistance. Direct endoscopic necrosectomy (DEN) was carried out in 31 of 52 cases (59.6%) of walled-off necrosis and in 2 of 4 cases (50%) of acute peripancreatic fluid collection. Complete resolution of the PFC was obtained in 86 cases (92.5%), with no recurrence during follow-up. Treatment failure occurred in 6 patients because of persistent infection requiring surgery (n = 3), perforation and massive bleeding caused by the nasocystic drainage catheter (NCDC) (n = 2), and the need for a larger opening to extract large necrotic tissue pieces (n = 1). Major adverse events occurred in 5 patients (perforation and massive bleeding caused by the NCDC in 2 patients, 1 pneumoperitoneum and 1 stent dislodgement during DEN, and 1 postdrainage infection) and were mostly not related to the drainage procedure. CONCLUSIONS EUS-guided drainage with the electrocautery-enhanced delivery system is a safe, easy to perform, and a highly effective minimally invasive treatment modality for PFCs.

Abstract
BACKGROUND EUS-guided pseudocyst drainage with fully covered self-expandable metal stents (FCSEMSs) was recently described. The appropriate period for stent removal is not known. OBJECTIVE To assess the safety and efficacy of EUS-guided FCSEMS placement for 3 weeks, along with pancreatic ductal stenting in selected patients. STUDY DESIGN Prospective, single-center evaluation. SETTING Tertiary referral center. PATIENTS Symptomatic pseudocysts in the body and tail region of the pancreas. INTERVENTIONS EUS-guided transgastric placement of FCSEMS. MRCP was performed after 3 weeks. Patients with a suspected pancreatic duct leak underwent ERCP and plastic stent placement. The FCSEMSs were removed at 3 weeks. MAIN OUTCOME MEASUREMENTS Success of FCSEMS placement, adverse events, and recurrence rate. RESULTS Forty-seven patients met the eligibility criteria. Technical and functional success was achieved in 43 patients (intention to treat, 91.48% and 95.34% patients [per protocol, 41/43, respectively]). Adverse events occurred in 2 patients (cyst infections, 4.6%). Follow-up of 42 patients at 3 weeks was performed. MRCP detected a ductal leak in 3 patients (7.1%) and a disconnected duct in 2 patients (4.7%). ERCP and stenting were successful in all 3 patients with a ductal leak. During a median follow-up of 306 days in 42 patients, 2 recurrences (4.7%) were detected, both in patients with disconnected duct. Multivariate analysis showed that pancreatic ductal leak or disconnection was an independent factor affecting pseudocyst resolution at 3 weeks (P = .0001). LIMITATIONS Single-center study. CONCLUSION Short-term placement of FCSEMSs with pancreatic ductal stenting in selected patients appears safe and effective for the treatment of pseudocysts.

Abstract
BACKGROUND Endoscopic management of walled-off pancreatic necrosis (WOPN) is an area of great interest with many still unanswered questions, including the role of mechanical necrosectomy versus irrigation. The aim of this study was to evaluate a new method of endoscopic transmural necrosectomy. METHODS Patients with WOPN after necrotizing pancreatitis, who underwent endoscopic transmural necrosectomy using a lumen-apposing metal stent with vigorous irrigation sessions, were prospectively recruited between September 2011 and August 2014. Initial endoscopic session was performed by EUS-guided drainage and lavage sessions by flushing saline through the stent. Technical and clinical success rates, number of repeat interventions, and adverse events were analyzed. RESULTS Twelve patients with 13 WOPN collections (median size 12.4 ± 2.94 cm) underwent endoscopic treatment. Clinical success was achieved in 100 % of cases after a median of three sessions per patient (range 2-8). The median length of hospitalization was 15.9 days. Median procedure time of the access session was 31 ± 10.16 min. No adverse events (AE) were described during the procedures or 24 h after. There were four AE (two infections and two bleedings) between sessions, but only two were severe (16.6 %). There was no need for surgery, and no mortalities occurred. Mean time to stent retrieval was 9 ± 3.4 weeks. Mean follow-up was 13 months with only one recurrence at 12 months after stent removal. CONCLUSIONS This new variant of irrigation endoscopic transmural necrosectomy without mechanical debridement helps to simplify the technique, is feasible, and has excellent outcomes in WOPN treatment.
