Which clip? A prospective comparative study of retention rates of endoscopic clips on normal mucosa and ulcers in a porcine model
Background/Aim: There are currently no data on the relative retention rates of the Instinct clip, Resolution clip, and QuickClip2Long. Also, it is unknown whether retention rate differs when clips are applied to ulcerated rather than normal mucosa. The aim of this study is to compare the retention rates of three commonly used endoscopic clips. Materials and Methods: Six pigs underwent upper endoscopy with placement of one of each of the three types of clips on normal mucosa in the gastric body. Three mucosal resections were also performed to create "ulcers." Each ulcer was closed with placement of one of the three different clips. Repeat endoscopy was performed weekly for up to 4 weeks. Results: Only the Instinct and Resolution clips remained attached for the duration of the study (4 weeks). At each time point, a greater proportion of Instinct clips were retained on normal mucosa, followed by Resolution clips. QuickClip2Long had the lowest retention rate on normal mucosa. Similar retention rates of Instinct clips and Resolution clips were seen on simulated ulcers, although both were superior to QuickClip2Long. However, the difference did not reach statistical significance. All QuickClip2Long clips were dislodged at 4 weeks in both the groups.
Conclusions: The Resolution and Instinct clips have comparable retention rates and both appeared to be better than the QuickClip2Long on normal mucosa-simulated ulcers; however this did not reach statistical significance. Both the Resolution clip and the Instinct clip may be preferred in clinical situations when long-term clip attachment is required, including marking of tumors for radiotherapy and anchoring feeding tubes or stents. Either of the currently available clips may be suitable for closure of iatrogenic mucosal defects without features of chronicity
A Novel Submucosal Gel Permits Simple and Efficient Gastric Endoscopic Submucosal Dissection
International multicenter experience with an over-the-scope clipping device for endoscopic management of GI defects (with video)
Copyright © 2014 by the American Society for Gastrointestinal Endoscopy.Background: The over-the-scope clip (OTSC) provides more durable and full-thickness closure as compared with standard clips. Only case reports and small case series have reported on outcomes of OTSC closure of GI defects. Objective: To describe a large, multicenter experience with OTSCs for the management of GI defects. Secondary goals were to determine success rate by type of defect and type of therapy and to determine predictors of treatment outcomes. Design: Multicenter, retrospective study. Setting: Multiple, international, academic centers. Patients: Consecutive patients who underwent attempted OTSC placement for GI defects, either as a primary or as a rescue therapy. Interventions: OTSC placement to attempt closure of GI defects. Main Outcome Measurements: Long-term success of the procedure. Results: A total of 188 patients (108 fistulae, 48 perforations, 32 leaks) were included. Long-term success was achiev
An international multicenter study comparing EUS-guided pancreatic duct drainage with enteroscopy-assisted endoscopic retrograde pancreatography after Whipple surgery.
BACKGROUND AND AIMS: Endoscopic management of post-Whipple pancreatic adverse events (AEs) with enteroscopy-assisted endoscopic retrograde pancreatography (e-ERP) is associated with high failure rates. EUS-guided pancreatic duct drainage (EUS-PDD) has shown promising results; however, no comparative data have been done for these 2 modalities. The goal of this study is to compare EUS-PDD with e-ERP in terms of technical success (PDD through dilation/stent), clinical success (improvement/resolution of pancreatic-type symptoms), and AE rates in patients with post-Whipple anatomy.
METHODS: This is an international multicenter comparative retrospective study at 7 tertiary centers (2 United States, 2 European, 2 Asian, and 1 South American). All consecutive patients who underwent EUS-PDD or e-ERP between January 2010 and August 2015 were included.
RESULTS: In total, 66 patients (mean age, 57 years; 48% women) and 75 procedures were identified with 40 in EUS-PDD and 35 in e-ERP. Technical success was achieved in 92.5% of procedures in the EUS-PDD group compared with 20% of procedures in the e-ERP group (OR, 49.3; P < .001). Clinical success (per patient) was attained in 87.5% of procedures in the EUS-PDD group compared with 23.1% in the e-ERP group (OR, 23.3; P < .001). AEs occurred more commonly in the EUS-PDD group (35% vs 2.9%, P < .001). However, all AEs were rated as mild or moderate. Procedure time and length of stay were not significantly different between the 2 groups.
CONCLUSIONS: EUS-PDD is superior to e-ERP in post-Whipple anatomy in terms of efficacy with acceptable safety. As such, EUS-PDD should be considered as a potential first-line treatment in post-pancreaticoduodenectomy anatomy when necessary expertise is available
Tu2049 Long term Outcomes of PerOral Endoscopic Myotomy (POEM) in Achalasia patients With a minimum follow-up of 2 years: A multicenter study:2016 DDW ASGE Program and AbstractsDDW 2016 ASGE Program and Abstracts
An international multicenter study evaluating the clinical efficacy and safety of per-oral endoscopic myotomy in octogenarians
Per-oral endoscopic myotomy (POEM) for achalasia is particularly appealing in the elderly due to its minimally invasiveness; however, data in patients age ≥ 80 years are scarce. The aim of this study was to assess the clinical outcome of POEM in octogenarians
