Endocuff Vision-Assisted Resection for Difficult Colonic Lesions-Preliminary Results of a Multicenter, Prospective Randomized Pilot Study. J Clin Med 2023; 12:4980. [PMID: 37568382 PMCID: PMC10420096 DOI: 10.3390/jcm12154980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Revised: 07/21/2023] [Accepted: 07/24/2023] [Indexed: 08/13/2023] Open
Abstract
Background-Screening programs for colorectal cancer are implemented due to their ability to reduce mortality. The Endocuff Vision is a new endoscopic device that significantly improves the adenoma detection rate. The primary outcome was to assess the efficacy of ECV in improving stability and reducing operation time during difficult colon polypectomies in a multicenter randomized prospective study. Methods-In a randomized multicenter pilot study, two groups of patients who underwent difficult polypectomies with and without the assistance of Endocuff Vision were compared. Demographics and clinical characteristics of patients were obtained, and polyps' size, morphology, site, and access (SMSA); polypectomy time; and endoscope stability were evaluated. Results-From October 2016 to April 2020, 32 patients were enrolled. In total, 12 patients underwent Endocuff Vision polypectomy, and 20 patients underwent standard polypectomy by using a computer-generated random number table. No statistical differences were found in clinical characteristics, SMSA, and polypectomy time. The most interesting findings were the positive correlations between shaking and SMSA (r = 0.55, p = 0.005) and shaking and polypectomy time (r = 0.745, p < 0.0001). Conclusion-Endocuff Vision seems to be adequately stable during difficult endoscopic resection procedures. The new parameter proposed that shaking is strongly correlated to the stability of the endoscope, the difficulty of the resection (SMSA), and the polypectomy time.

Abstract
INTRODUCTION Colorectal cancer (CRC) is the third most common malignancy and second leading cause of cancer-related mortality in the world. Adenoma detection rate (ADR), a quality indicator for colonoscopy, has gained prominence as it is inversely related to CRC incidence and mortality. As such, recent efforts have focused on developing novel colonoscopy devices and technologies to improve ADR. AREAS COVERED The main objective of this paper is to provide an overview of advancements in the fields of colonoscopy mechanical attachments, artificial intelligence-assisted colonoscopy, and colonoscopy optical enhancements with respect to ADR. We accomplished this by performing a comprehensive search of multiple electronic databases from inception to September 2023. This review is intended to be an introduction to colonoscopy devices and technologies. EXPERT OPINION Numerous mechanical attachments and optical enhancements have been developed that have the potential to improve ADR and AI has gone from being an inaccessible concept to a feasible means for improving ADR. While these advances are exciting and portend a change in what will be considered standard colonoscopy, they continue to require refinement. Future studies should focus on combining modalities to further improve ADR and exploring the use of these technologies in other facets of colonoscopy.

Second-generation distal attachment cuff improves adenoma detection rate: meta-analysis of randomized controlled trials. Gastrointest Endosc 2021; 93:544-553.e7. [PMID: 33031786 DOI: 10.1016/j.gie.2020.09.045] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Accepted: 09/19/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Multiple randomized controlled trials (RCTs) using the second-generation distal attachment cuff device (Endocuff Vision; Olympus America, Center Valley, Pa, USA) have reported conflicting results in improving adenoma detection rate (ADR) compared with standard high-definition colonoscopy without the distal attachment. We conducted a systematic review and meta-analysis of RCTs to compare outcomes between second-generation cuff colonoscopy (CC) versus colonoscopy without the distal attachment (standard colonoscopy [SC]). METHODS An electronic literature search was performed using PubMed, Google Scholar, Embase, and Cochrane Library through May 2020. The primary outcome was reporting of ADR, and secondary outcomes were polyp detection rate (PDR), mean withdrawal time, mean adenomas per colonoscopy (APC), sessile serrated lesion detection rate, and adverse events. Pooled rates and risk ratios (RRs) with 95% confidence intervals were reported. RESULTS Eight RCTs with 5695 patients were included in the final analysis, with 2862 patients (mean age, 62.8 years; 52.9% men) in the CC group and 2833 patients (mean age, 62.6 years; 54.2% men) in the SC group. Compared with SC, use of CC was associated with a significant improvement in ADR (49.8% vs 45.6%, respectively; RR, 1.12; P = .02), PDR (58.1% vs 53%, respectively; RR, 1.12; P = .009), and APC (P < .01). Furthermore, use of CC had a .93-minute lower mean withdrawal time (P < .01) when compared with SC. The difference in ADR was larger in the screening/surveillance population (6.5%, P = .02) and when used by endoscopists with ADRs <30% (9.4%, P = .03). CONCLUSIONS The results of this meta-analysis of randomized trials show a significant improvement in ADR and APC with shorter withdrawal times using the second-generation cuff device compared with SC.

Abstract
Background/Aims The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The effcacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the effcacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the effcacy between EAC and CAC in trainees.
Methods This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups.
Results The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group.
Conclusions Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees.

Randomized control trial of adenoma detection rate in Endocuff-assisted colonoscopy versus transparent hood-assisted colonoscopy. J Gastroenterol Hepatol 2019; 34:1492-1496. [PMID: 31254485 DOI: 10.1111/jgh.14771] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2019] [Revised: 03/30/2019] [Accepted: 06/20/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIM Transparent hood-assisted colonoscopy (TAC) has been reported to improve the cecal insertion rate and adenoma detection rate (ADR). An endoscopic cap (Endocuff) with two rows of soft wings was recently developed to improve ADR, by flattening the mucosal folds during withdrawal. This randomized prospective control study aimed to compare ADR between Endocuff-assisted colonoscopy (EAC) and TAC. METHODS A total of 513 patients undergoing colon adenoma screening were included. EAC was performed in 256 patients and TAC in 260 patients. Cecal intubation rate, cecal intubation time, ADR, and mean adenoma number per patient (MAP) were investigated in both groups (clinical trial registration: UMIN000016278). RESULTS We excluded six patients in the EAC group and two patients in the TAC group because of colonic stenosis due to colonic adenocarcinomas. Finally, 250 patients (151 men/99 women, median age 62.1 years) were assigned to EAC and 258 patients (165 men/93 women, median age 64.3 years) were assigned to TAC. There were no significant differences in cecal intubation rate, intubation time, withdrawal time, and cleanliness score between groups. The ADR was 50.8% in EAC and 52.7% in TAC, with no significant difference (P = 0.666). The MAP was 1.35 in EAC and 1.20 in TAC, with no significant difference (P = 0.126). However, The MAP of diminutive adenomas (< 5 mm) tended to be higher in EAC than in TAC (P = 0.077). There was no significant difference in MAP in each segment between groups. CONCLUSIONS Endocuff-assisted colonoscopy might be equivalent to TAC in cecal intubation time, ADR, and MAP.

Abstract
BACKGROUND AND AIMS The need to increase the adenoma detection rate (ADR) for colorectal cancer screening has ushered in devices that mechanically or optically improve conventional colonoscopy. Recently, new technology devices (NTDs) have become available. We aimed to compare the ADR, polyp detection rate (PDR), and adenoma miss rate (AMR) between NTDs and conventional colonoscopy and between mechanical and optical NTDs. METHODS MEDLINE and Embase databases were searched from inception through September 2017 for articles or abstracts reporting ADR, PDR, and AMR with NTDs. Randomized controlled trials and case-control studies with >10 subjects were included. Primary outcomes included ADR, PDR, and AMR odds ratio (OR) between conventional colonoscopy and NTDs. Secondary outcomes included cecal intubation rates, adverse events, cecal intubation time, and total colonoscopy time. RESULTS From 141 citations, 45 studies with 20,887 subjects were eligible for ≥1 analyses. Overall, the ORs for ADR (1.35; 95% confidence interval [CI] 1.24-1.47; P < .01) and PDR (1.51; 95% CI, 1.37-1.67; P < .01) were higher with NTDs. Higher ADR (OR, 1.52 vs 1.25; P = .035) and PDR (OR, 1.63 vs 1.10; P ≤ .01) were observed with mechanical NTDs. The overall AMR with NTDs was lower compared with conventional colonoscopy (OR, .19; 95% CI, .14-.26; P < .01). Mechanical NTDs had lower AMRs compared with optical NTDs (OR, .10 vs .33; P < .01). No differences in cecal intubation rates, cecal intubation time, or total colonoscopy time were found. CONCLUSIONS Newer endoscopic technologies are an effective option to improve ADR and PDR and decrease AMR, particularly with mechanical NTDs. No differences in operability and safety were found.

Abstract
Background Currently, colonoscopy and polypectomy are the gold standard methods for the prevention of incident cases of colorectal cancer. The use of a new colonoscope (Fuse®, EndoChoice®) with a larger view of up to 330° appears to improve the adenoma detection rate (ADR). We performed a prospective observational study concerning this scope. The primary endpoint was potentially omitted adenomas (POA), i.e. adenomas seen on the side screens that will not appear on the central display during colonoscopy withdrawal without oriented movements. Secondary endpoints included our ADR, Fuse® impact on ADR, time to cecal intubation and withdrawal time. Methods We performed a single-center prospective study in one French center. We enrolled patients over 18 years of age between January 2015 and March 2016. Results We included 141 patients; 3 were excluded because their colonoscopies were incomplete. Our study included 78 men and 60 women (sex ratio 1.3). The mean age was 60.4 years. A total of 130 polyps were resected. In all, 88/130 were adenomas (68%) and 34/88 adenomas (39%) were POA. The mean time to cecum was 10 min, and the mean withdrawal time was 12 min. ADR was 35% for men and 31% for women. The estimated ADR without POA was 29% for men and 19% for women. Conclusions The Fuse® system appears to be safe and efficient. POA represented 39% of all adenomas. The impact of the panoramic view on the ADR was considered substantial. The main limitations are the lack of randomization and the absence of a control group.

Abstract
It is well-known that colonoscopy is considered the gold standard for colon cancer prevention. Although performed by experienced endoscopists, the matter remains of polyps missed during this examination. The reasons may include the size, shape and location of the lesions. Many colorectal cancer screening programs have been proposed to increase the adenoma detection rate. The substantial difference between these methods is whether the improvement in vision, particularly the detection of irregularities of the mucosa, is inside the endoscope electronic components (magnification, wide-angle vision, narrow band imaging, flexible spectral imaging colour enhancement, i-Scan) or outside the same, by the use of specific caps (EndoCuff, EndoVision, EndoRings). Endocuff is a plastic device mounted at the end of the scope with a constant vision field of the entire colon. The aim of this study is to explore the potential clinical and technical benefits of Endocuff.

Abstract
High-quality colonoscopy is mandatory to prevent adenoma recurrence and colorectal cancer. In the past few years, technical advances have been developed with the purpose of improving adenoma detection rate (ADR), one of the most important validated colonoscopy quality benchmarks. Several techniques or devices are used to optimize visualization: observation techniques; add-on devices; auxiliary imaging devices; colonoscopes with increased field of view; and colonoscopes with an integrated inflatable reusable balloon. Image-enhanced endoscopy (IEE) facilitates the detection and characterization of polyps and especially nonpolypoid colorectal neoplasms. Indigo carmine is the most frequently used dye in colonoscopy as it deposits in depressed areas, improving detection of flat and depressed lesions. Virtual chromoendoscopy has emerged as an effective contrast enhancement technology without the limitation of preparing dyes and applying them through the colonoscope working channel. Narrow-band imaging (NBI) enhances the capillary pattern and surface of the mucosa using optical filters, and second-generation NBI provides a twofold brighter image than the previous system, yielding promising ADR results. Moreover, a second-generation blue laser imaging system, LASEREO, has been reported to improve not only polyp detection rate but also ADR, becoming a promising IEE modality. Herein, we describe technical advances in colonoscopy imaging and their effect on ADR.

Abstract
BACKGROUND The presence of colorectal adenomas is considered a major risk factor for colorectal cancer development. The implementation of screening colonoscopy programs in the Western world has led to a substantial reduction of colorectal cancer death. Many efforts have been made to reduce the adenoma miss rates by the application of new endoscopic devices and techniques for better adenoma visualization. SUMMARY This special review gives the readership an overview of current endoscopic innovations that can aid in the increase of the adenoma detection rate (ADR) during colonoscopy. These innovations include the use of devices like EndoCuff® and EndoRings® as well as new technical equipment like third-eye endoscope® and full-spectrum endoscopy (FUSE®). KEY MESSAGE Technical improvements and newly developed accessories are able to improve the ADR. However, additional costs and a willingness to invest into potentially expensive equipment might be necessary. Investigator-dependent skills remain the backbone in the ADR detection.

Abstract
Endocuff (Arc Medical Design) is a U.S. Food and Drug Administration-approved device that is attached like a cap to the distal tip of the colonoscope; it is used to improve adenoma detection rates during colonoscopy. The aim of this review was to summarize and evaluate the clinical and technical efficacy of Endocuff in improving adenoma detection rate. A comprehensive literature review was performed to identify studies describing this technique. In this review article, we have summarized case series and reports describing Endocuff use and results. The reported indications, results, limitations, and complications are discussed.

[PMID: 26937150 PMCID: PMC4768208 DOI: 10.3748/wjg.v22.i8.2621] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2015] [Revised: 10/20/2015] [Accepted: 11/19/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the full-spectrum endoscopy (FUSE) colonoscopy system as the first report on the utility thereof in a Korean population.
METHODS: We explored the efficacy of the FUSE colonoscopy in a retrospective, single-center feasibility study performed between February 1 and July 20, 2015. A total of 262 subjects (age range: 22-80) underwent the FUSE colonoscopy for colorectal cancer screening, polyp surveillance, or diagnostic evaluation. The cecal intubation success rate, the polyp detection rate (PDR), the adenoma detection rate (ADR), and the diverticulum detection rate (DDR), were calculated. Also, the success rates of therapeutic interventions were evaluated with biopsy confirmation.
RESULTS: All patients completed the study and the success rates of cecal and terminal ileal intubation were 100% with the FUSE colonoscope; we found 313 polyps in 142 patients and 173 adenomas in 95. The overall PDR, ADR and DDR were 54.2%, 36.3%, and 25.2%, respectively, and were higher in males, and increased with age. The endoscopists and nurses involved considered that the full-spectrum colonoscope improved navigation and orientation within the colon. No colonoscopy was aborted because of colonoscope malfunction.
CONCLUSION: The FUSE colonoscopy yielded a higher PDR, ADR, DDR than did traditional colonoscopy, without therapeutic failure or complications, showing feasible, effective, and safe in this first Korean trial.
