Simplified Submucosal Tunneling Biopsy Using Clip-With-Line Traction and Closure for Gastric Subepithelial Lesion.

ABSTRACT: Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) has emerged as a standard and convenient method for the sampling of subepithelial lesions (SELs). Immunohistological analysis is required to definitively distinguish mesenchymal tumors; however, EUS-FNA provides insufficient material to achieve this, especially for small SELs < 2 cm. We therefore previously reported a novel submucosal tunneling biopsy (STB) technique that utilizes endoscopic submucosal dissection (ESD) for sampling SELs. However, unresolved advanced technical issues have hindered its widespread application. Currently, a counter-traction technique is used to facilitate ESD. We here describe a technically simplified STB technique using clip-with-line traction for gastric SELs.

Traction-assisted colonic endoscopic submucosal dissection using clip and line: a feasibility study.

Project description:Colonic endoscopic submucosal dissection (ESD) is a challenging procedure because it is often difficult to maintain good visualization of the submucosal layer. To facilitate colonic ESD, we designed a novel traction method, namely traction-assisted colonic ESD using clip and line (TAC), and investigated its feasibility.We retrospectively analyzed 23 patients with large colonic superficial lesions who had undergone TAC. The main outcome was the procedural success rate of TAC, which we defined as successful, sustained application of clip and line to the lesion until the end of the procedure.The procedural success rate of TAC was 87 % (20/23). In all three unsuccessful cases, the lesions were in the proximal colon and the procedure times over 100 minutes. The overall mean procedure time was 61 min (95 % confidence interval, 18 - 172 min). We achieved en bloc resections of all lesions. There were no perforations or fatal adverse events.TAC is feasible and safe for colonic ESD and may improve the ease of performing this procedure.

Mucosal defect closure after duodenal endoscopic submucosal dissection using the reopenable-clip over the line method.

Project description:IntroductionClosure of mucosal defects after duodenal endoscopic submucosal dissection (ESD) is important to prevent postoperative adverse events. Previously, we devised an underwater reopenable-clip closure method for effective closure of mucosal defects under endoscopic guidance within the field of view. Recently, the usefulness of a method using a clip with a line passing through an accessory channel to close a mucosal defect has been reported. We also described a reopenable-clip over the line method (ROLM) to completely close margin and the muscular layers of mucosal defects using a clip line.Case reportOur patient was a 70-year-old woman with a 40-mm duodenal tumor in the descending portion of the duodenum. The lesion was completely resected using ESD . In the result, the mucosal defect size was approximately 50 mm, representing about 3/4 of the duodenal circumference. A clip-line closure was performed using ROLM to close the mucosal defect's margins completely. An additional clip was applied to close the mucosal defect after ESD completely. Subsequently, the line was fixed with a modified locking-clip technique, closed, and cut with endoscopic scissors. The patient was discharged without any adverse events 9 days after the duodenal ESD.DiscussionMucosal defect closure after duodenal ESD using ROLM is a novel method that can reliably close mucosal defects.

Comparison of submucosal tunneling biopsy versus EUS-guided FNA for gastric subepithelial lesions: a prospective study with crossover design.

Project description:Endoscopic ultrasound-guided fine needle aspiration (FNA) for gastrointestinal subepithelial lesions (SELs) has limited diagnostic accuracy due to technical problems and small lesion size. We previously reported a novel submucosal tunneling biopsy (STB) technique for sampling SELs. This study aimed to evaluate the diagnostic ability and safety of STB compared to that of FNA for SELs.The study was a non-randomized, prospective comparative study with crossover design in patients with endoluminal gastric SELs. Forty-three patients, including 29 cases with lesions < 2 cm were enrolled. A crossover design with 2 intervention stages (Group A: FNA followed by STB for 23 SELs, Group B: STB followed by FNA for 20 SELs) was implemented. The primary outcome was the diagnostic yield (DY). Secondary outcomes were technical success rate, procedure time, complication rate, and sample quality.The DY of STB was significantly higher than that of FNA (100 % vs. 34.8 %; P < 0.0001) in group A, including 100 % in overall STB. The technical success rate of STB was significantly higher than that of FNA (100 % vs. 56.5 %; P = 0.0006), whereas the median procedure time of STB was significantly longer than that of FNA (37 minutes vs. 18 minutes; P < 0.0001). The median specimen area of STB samples was markedly larger than that of FNA samples (5.54 mm 2 vs. 0.69 mm 2 ; P < 0.001). No complications occurred in either method. STB had significantly superior diagnostic ability and a more adequate sample quality than FNA for endoluminal gastric SELs, indicating the suitability of STB for small SELs.UMIN 000006754.

Internal traction method using a spring-and-loop with clip (S-O clip) allows countertraction in gastric endoscopic submucosal dissection.

Project description:BackgroundInsufficient countertraction and poor field of vision make endoscopic submucosal dissection (ESD) difficult. Internal traction method using a spring-and-loop with clip (SLC) allows sufficient traction in any direction and good field of vision. However, the attachment procedure is difficult and interference with the endoscope can occur in the retroflexed endoscopic position. We have developed a new use of SLC that simplifies the attachment procedure, eliminating interference with the endoscope. The aim of this study was to investigate the efficacy of SLC for gastric ESD.MethodsWe retrospectively recruited 140 patients with gastric neoplasms who underwent ESD between November 2015 and October 2018 at our department. Among them, 51 patients treated using SLC-assisted ESD (SLC-ESD) and 89 patients treated using conventional ESD (C-ESD) were compared. Propensity score matching was performed to compensate for the differences in age, sex, lesion location, lesion position, specimen size, and ulcer findings. The primary outcome was ESD procedure time.ResultsPropensity score matching generated 51 matched pairs. The procedure time in the SLC-ESD group was significantly shorter than that in the C-ESD group (median [interquartile], 40.0 [27.0-81.5] minutes versus 69.0 [46.5-113.5] minutes, P = 0.008). The mean SLC attachment time was 2.08 min. There were no significant differences in complete en bloc resection rate between SLC-ESD and C-ESD groups (100% versus 96.1%, P = 0.495). There were not perforation cases in either group.ConclusionsSLC may offer an efficient method for gastric ESD, with a short attachment procedure time.
