There have been many reports about the relationship between reflux oesophagitis and obesity, but not metabolic syndrome.To review upper gastrointestinal endoscopic findings screening data obtained in healthy subjects, assess relations features of syndrome.In 3599 men 1560 women, prevalence was assessed relation to age, body mass index, blood pressure, triglycerides fasting glucose. Logistic regression analysis used calculate odds ratio for risk factors.The overall 4%, it increased with age...
To analyze factors involved in procedural failure and to discuss responses by using the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) carried out a short-type single-balloon enteroscope (short SBE) patients with surgically altered gastrointestinal anatomy.The study sample included who underwent ERCP-related procedures short SBE between September 2011 2018 at our hospital. Outcomes, including success rate, were studied retrospectively failure.Analysis 191 121 patients....
Abstract Background and aims In recent years, the short single-balloon enteroscope (SBE) has been used during endoscopic retrograde cholangiopancreatography (ERCP) for patients with surgically altered anatomy reported to be useful. However, difficulties remain, procedures devices need improvements. We assessed usefulness superiority of a new SBE equipped passive bending high-force transmission by comparisons outcomes using conventional SBE. Methods This study evaluated SBE-assisted...
Endoscopic nasobiliary drainage (ENBD) is often recommended in preoperative biliary (PBD) for hilar malignant obstruction (MBO), but endoscopic stent (EBS) also used the clinical practice. We conducted this large-scale multicenter study to compare ENBD and EBS setting.A total of 374 cases undergoing PBD including 281 76 MBO 29 centers were retrospectively studied.Extrahepatic cholangiocarcinoma (ECC) accounted 69.8% Bismuth-Corlette classification was III or more 58.8% population....
Endoscopic stone extraction using a balloon enteroscope in patients with Roux-en-Y anastomosis is challenging due to the difficulty aligning axis between retrieval devices and stones, which often results failure of capture [1] [2]. Recently, it has been reported that novel thin cholangioscope (EyeMax; Micro-Tech, China), length 219 cm diameter 9 Fr, enables peroral cholangioscopy (POCS)-guided procedures 3.2-mm forceps channel ([Fig. 1]) [3] [4]. Furthermore, also POCS-guided basket...
Endoscopic ultrasound-guided tissue acquisition (EUS-TA) is a crucial method for diagnosing pancreatic lesions [1] [2] [3] [4] [5]. The Aplio i800 ultrasound device (Canon Medical Systems, Tochigi, Japan) features superb microvascular imaging (SMI), which provides highly sensitive and high-resolution of flow without contrast agents. SMI has two modes – monochrome (mSMI), isolates signals, color-coded (cSMI), enhances the visibility pulsatile flow. These complement each other, enabling...
AIM:To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal obstruction.CONCLUSION: PS has insufficient patency drainage.Given drawbacks external via NBC, an alternative internal should be explored.
Background/Aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the yield and puncturing ability of EUS-TA 22-gauge cobalt-chromium (CO-Cr) with those stainless-steel in patients solid pancreatic lesions.Methods: Outcomes were between Co-Cr needle (December 2019 to November 2020; group C) (November 2020 May 2022; S).Results: A total 155 (group C, 75; S, 80) eligible. The accuracy was...
Abstract Background and study aims Endoscopic resection of duodenal neuroendocrine tumors (DNETs) remains controversial, its indications are still unclear. This aimed to evaluate short-term outcomes a newly developed endoscopic muscularis (EMR) method that utilizes an over-the-scope clip (OTSC), termed EMRO, for treating DNETs. Patients methods In total, 13 consecutive patients with 14 small (≤ 10 mm) DNETs who underwent EMRO from September 2017 March 2020 were retrospectively enrolled. was...
The differential diagnosis of gastrointestinal subepithelial lesions (SELs) such as stromal tumors from other benign is important. In the present study, adequate sample rates endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with a 22G Franseen for SELs were evaluated. study included 57 consecutive (61 sessions) EUS-FNA using to evaluate between July 2013 and October 2017. Adequate compared retrospectively conventional group (C group) (F group). overall rate was 80.3%. in C F...
To evaluate the efficacy and safety of self-expandable metal stent (SEMS) placement for unresectable malignant biliary obstruction (MBO) using a short-type single-balloon enteroscopy (short SBE) in patients with surgically altered anatomy (SAA).The technical success rate, clinical recurrent (RBO), time to RBO (TRBO), procedure related adverse events, reintervention after were evaluated from September 2011 June 2020.Thirty-seven (11 distal MBO 26 hilar MBO) who underwent SEMS included...
Abstract Colorectal endoscopic submucosal dissection (ESD) is a difficult procedure, and its introduction to trainees has been debated. Although the criteria for performing colorectal ESD vary among institutions, it often allowed after gaining experience surgeries in animals upper gastrointestinal ESD. This pilot study aimed compare treatment outcomes of performed by using multi-loop traction device (MLTD group) those conventional experts (control group). It also determine whether MLTD can...
Texture and color enhancement imaging (TXI) reportedly improves the identification of papilla Vater for selective biliary cannulation compared with white light (WLI). This multicenter study evaluated efficacy short-type single-balloon enteroscopy (SBE)-assisted using a new-generation image-enhanced endoscopy processing system equipped TXI in patients who underwent Roux-en-Y gastrectomy.
Balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) is useful in patients with a hepaticojejunal anastomotic stricture [1] [2] [3]. However, biliary cannulation for such challenging especially cases steep angle, because the balloon enteroscope has no elevator function to angulate catheter. We report case of successful using novel rotatable sphincterotome patient at angle.
Stone extraction using endoscopic retrograde cholangiopancreatography (ERCP) is less invasive than surgical procedures. However, stone in patients with surgically altered anatomy, such as those who have undergone a Roux-en-Y procedure, challenging. Although balloon enteroscopy useful for cases, there still room improvement [1] [2]. Peroral cholangioscopy (POCS)-guided lithotripsy can aid the of stones that are difficult to remove [3] [4]. performing POCS-guided under because cholangioscopes...
Although the potential advantages of Endocut mode (E-mode) endoscopic sphincterotomy (EST) over conventional blended cut (C-mode) have been reported, problems, including small sample size and retrospective analysis, that occurred in previous studies make it difficult to conclude advantage E-mode regarding safety efficacy. We performed a prospective randomized controlled study compare these modes.A total 360 patients with choledocholithiasis or stenosis bile duct were randomly assigned one...
Objective We investigated the results of biliary cannulation using a short-type single-balloon enteroscope in patients with native papilla who had previously undergone Roux-en-Y gastrectomy and analyzed factors associated successful cannulation. Methods The study subjects consisted endoscopic retrograde cholangiopancreatography at our institution between September 2011 July 2019. carried out retrospective investigation outcomes, including assessing success rate cannulation, Results In total,...
Abstract Objectives Understanding the exact morphology of bile duct opening is important for determining success cannulation. Texture and color enhancement imaging (TXI) has been reported to enhance slight changes in tone structure that are difficult see with white light imaging. This study investigated whether TXI mode1 could improve papillary recognition by trainees inexperienced endoscopic retrograde cholangiopancreatography. Methods We included 31 patients naive papilla Vater at a single...
