A novel bipolar electrocautery-enhanced delivery system with a lumen-apposing metal stent for EUS-guided drainage: A porcine study. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2023; 30:263-268. [PMID: 35583204 DOI: 10.1002/jhbp.1180] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 03/02/2022] [Accepted: 03/27/2022] [Indexed: 11/08/2022]
Abstract
BACKGROUND An electrocautery-enhanced delivery system with a lumen-apposing metal stent (LAMS) is available for one-step endoscopic ultrasound-guided transmural drainage (EUS-TD). Bipolar electrosurgery has several potential clinical advantages, including reduced collateral thermal damage, enhanced hemostasis, and no requirement for a return electrode plate. In this study, we compared the technical feasibility and safety of a newly developed bipolar electrocautery-enhanced delivery system with a conventional delivery system for EUS-TD using a LAMS in a porcine model. METHOD Ten days before the study, 12 mini pigs underwent common bile duct ligation for EUS-guided gallbladder drainage. Transenteric puncture was performed, followed by placement of a guidewire. In six pigs, a bipolar electrocautery-enhanced delivery system with LAMS (Hot SPAXUS) was inserted over the guidewire and advanced into the gallbladder, without prior dilation of the tract, by applying a bipolar cut current. In the remaining six pigs, a conventional delivery system with LAMS (Cold SPAXUS) was inserted after tract dilatation using a cystotome. The stent was removed after 4 weeks. RESULTS In all pigs, the stent was successfully inserted and deployed in the gallbladder without adverse events. The mean procedure time of EUS-TD was significantly lower in the Hot SPAXUS group than that of the Cold SPAXUS group (mean ± standard deviation: 188.7 ± 5.2 vs 449.5 ± 97.5 s, P = .0019). Stent migration was not observed, and all stents were removed successfully. CONCLUSIONS Endoscopic ultrasound-guided transmural drainage using a bipolar electrocautery-enhanced LAMS is feasible for reducing the procedure time while maintaining the high success rate and safety of conventional LAMS.

Experimental study of a physician-controlled electrocautery-enhanced delivery system incorporating a newly developed lumen-apposing metal stent for interventional endoscopic ultrasound (with videos). JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2022; 29:817-824. [PMID: 35030302 DOI: 10.1002/jhbp.1113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 12/09/2021] [Accepted: 12/16/2021] [Indexed: 11/07/2022]
Abstract
BACKGROUND/PURPOSE Although the lumen-apposing metal stent (LAMS) is useful for interventional endoscopic ultrasound (EUS) procedures, there has been some concern about the potential for stent-induced adverse events because of the high lumen-apposing force. A newly designed LAMS with less lumen-apposing force has been developed for use with a physician-controlled electrocautery-enhanced delivery system. The aim of this animal study was to evaluate the feasibility of performing interventional EUS using this newly designed LAMS system. METHODS EUS-guided cystogastrostomy was performed using the novel LAMS 3 times in a wet simulation model. EUS-guided gastroenterostomy and EUS-guided gallbladder drainage were then performed using the system in 4 pigs. RESULTS The LAMS was successfully placed in all 3 EUS-guided cystogastrostomy procedures using the wet simulation model and in all 4 EUS-guided gastroenterostomy and gallbladder drainage procedures in the animal model. In the 3 weeks following the procedure, eating behavior was normal in all animals and there were no adverse events. The stents remained patent during this time and were removed without difficulty. The fistula was mature in all cases and a standard upper gastrointestinal endoscope was easily advanced via the fistula to observe the afferent and efferent loops or the lumen of the gallbladder. Necropsy confirmed complete adhesion between the stomach and the wall of the jejunum or gallbladder. CONCLUSIONS Our study findings demonstrate the feasibility of this new LAMS system and its potential clinical value for interventional EUS.

Comparative outcomes of endoscopic ultrasound-guided lumen-apposing mental stents drainage for pancreatic pseudocysts and walled-off necrosis: Case series and meta-analysis. Chronic Dis Transl Med 2021; 7:157-168. [PMID: 34505016 PMCID: PMC8413123 DOI: 10.1016/j.cdtm.2021.07.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Indexed: 12/29/2022] Open
Abstract
Background Endoscopic 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). Methods A 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. Results Combining 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. Conclusions Endoscopic 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.

Head-to-head comparison between endoscopic ultrasound guided lumen apposing metal stent and plastic stents for the treatment of pancreatic fluid collections: A systematic review and meta-analysis. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2021; 29:198-211.

Abstract
BACKGROUND/AIMS Peripancreatic fluid collections (PFCs) result from acute or chronic pancreatic inflammation that suffers a rupture of its ducts. Currently, there exists three options for drainage or debridement of pancreatic pseudocysts and walled-off necrosis (WON). The traditional procedure is drainage by placing double pigtail plastic stents (DPPS); lumen-apposing metal stent (LAMS) has a biflanged design with a wide lumen that avoids occlusion with necrotic tissue, which is more common with DPPS and reduces the possibility of migration. We performed a systematic review and meta-analyses head-to-head, including only studies that compare the two main techniques to drainage of PFCs: LAMS vs DPPS. METHODS We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. This meta-analysis considers studies published from 2014 to 2020, including only studies that compare the two main techniques to drainage of PFCs: LAMS vs DPPS. RESULTS Thirteen studies were included in the meta-analyses. Only one of all studies was a randomized controlled trial. These studies comprise 1584 patients; 68.2% were male, and 31.8% were female. Six hundred sixty-three patients (41.9%) were treated with LAMS, and 921 (58.1%) were treated with DPPS. Six studies included only WON in their analysis, two included only pancreatic pseudocysts, and five studies included both pancreatic pseudocysts and WON. The technical success was similar in patients treated with LAMS and DPPS (97.6% vs 97.5%, respectively, P = .986, RR = 1.00 [95% CI 0.93-1.08]). The clinical success was similar in both groups (LAMS: 90.1% vs DPPS: 84.2%, P = .139, RR = 1.063 [95% CI 0.98-1.15]). Patients treated with LAMS had a lower complication rate than the DPPS groups, with a significant statistical difference (LAMS: 16.0% vs DPPS: 20.2%, P = .009, RR = 0.746 [95% CI 0.60-0.93]). Bleeding was the most common complication in the LAMS group (33 patients, [5.0%]), whereas infection was the most common complication in the DPPS group (56 patients, [6.1%]). The LAMS migration rate was lower than in the DPPS (0.9% vs 2.2%, respectively, P = .05). The mortality rate was similar in both groups, 0.6% in the LAMS group (four patients) and 0.4% in the DPPS group (four patients; P = .640). CONCLUSION The PFCs drainage is an indication when persistent symptoms or PFCs-related complications exist. EUS guided drainage with LAMS has similar technical and clinical success to DPPS drainage for the management of PFCs. The technical and clinical success rates are high in both groups. However, LAMS drainage has a lower adverse events rate than DPPS drainage. More randomized controlled trials are needed to confirm the real advantage of LAMS drainage over DPPS drainage.

Abstract
BACKGROUND & AIMS Acute Pancreatitis (AP) tends to have a benign course in children. However there is a paucity of information with respect to severity of AP in children, the categorization of collections viz., walled off necrosis (WON)& pseudocyst and their natural history & outcomes. METHODS A retrospective medical record review of 187 children with pancreatitis diagnosed and managed at our centre was performed. RESULTS 101 children (59% boys, Median age 9yrs) had AP of which 37.6%, 60.4% and 2% had mild, moderately severe and severe AP. 61.4%(62) had PFC at diagnosis; 34%(21) acute pancreatic fluid collections (APFC) and 66%(41) acute necrotic collections (ANC). 52.3%(11of21) of APFC evolved into pseudocysts & 68.2%(28of41) of ANC into WON's. Drainage was required in 31%(12of39) of persisting collections, more frequently in children with traumatic AP. Percutaneous catheter drainage (PCD) was done in 6 children and endoscopic ultrasound (EUS) guided cystogastrostomy with placement of plastic or self expanding metal stents (SEMS) in 6 children. CONCLUSIONS Moderately severe AP is common in hospitalized children with AP with PFC developing in 61.4%, majority being APFC. 48% of APFC and 32% of ANC will resolve and the rest evolve into pseudocyst or WON. Spontaneous resolution is more likely in children with non -traumatic AP having pseudocysts rather than WON's.

Abstract
Background Lumen-apposing metal stents (LAMS) were considered a breakthrough in the endoscopic management of walled-off necrosis (WON), as their larger drainage diameter was expected to provide effective drainage of necrotic material. However, various studies and meta-analyses that have compared plastic and metal stents for the treatment of WON have shown conflicting results. We retrospectively compared the efficacy and safety of endoscopic transmural drainage between multiple plastic stents and LAMS. Methods Endoscopic data were retrospectively retrieved for patients who had undergone endoscopic ultrasound (EUS)-guided drainage/debridement of WON. Patients were divided into 2 groups according to whether multiple plastic stents or LAMS were deployed during initial drainage. The resolution and complication rates were compared between the 2 groups. Results One hundred sixty-six patients (83% male, mean age 37.5 years) with symptomatic WON were treated with EUS-guided drainage using either multiple plastic stents (n=138) or LAMS (n=28). Patients in the LAMS group had significantly larger WON and a significantly higher proportion of solid content. WON resolution rates did not differ between plastic stents and LAMS (98.5% vs. 96.4% respectively, P=0.42). However, the time taken to resolution was significantly shorter in the LAMS group than in the plastic stents group (26.7 vs. 29.8 days, P=0.03). There was no significant difference between the groups in either mortality or complication rates. Conclusions The technical success, rates of WON resolution and complications were similar in patients treated with multiple plastic stents and LAMS. However, LAMS were associated with a significantly shorter time to resolution.
