The endoscopic treatment of symptomatic pharyngoesophageal diverticula (PED) with rigid instruments involves the incision septum between diverticulum and esophageal lumen, within which cricopharyngeal muscle is present. aim this study to report on feasibility efficacy our method using flexible endoscopy an electro-surgery system minimal trauma patients.Forty-two patients (13 female, 29 male) underwent treatment. average age was 68.4 years (range 46 102 years) 26 them (61%) had concomitant...
To evaluate if using a soft-tipped guidewire to cannulate the common bile duct may ameliorate development of post-ERCP pancreatitis and facilitate cannulation CBD.A single-center, blinded, randomized trial conventional technique sphinctertome contrast injection versus technique.We prospectively 300 patients (group I) or II) technique.Primary outcome measure was incidence acute secondary measures were ease (assessed by attempts required for & rates precut sphincterotomy) overall complication...
The purpose of this study was to evaluate the effect duodenal-jejunal bypass liner (DJBL), a 60-cm, impermeable fluoropolymer anchored in duodenum create bypass, on metabolic parameters obese subjects with type 2 diabetes.Twenty-two (mean age, 46.2±10.5 years) diabetes and body mass index between 40 60 kg/m(2) index, 44.8±7.4 kg/m(2)) were enrolled 52-week, prospective, open-label clinical trial. Endoscopic device implantation performed patient under general anesthesia, examined periodically...
BACKGROUND AND AIMS Both endoscopic and surgical drainage procedures are effective palliative methods for malignant biliary obstruction. Surgical is still preferred in developing countries due to the high cost of procuring metal stents. The aim this study was evaluate quality life care patients with metastatic pancreatic cancer after drainage. PATIENTS METHODS This a prospective, randomized controlled trial conducted tertiary referral center Brazil. Patients obstruction liver metastasis, but...
Background and Study Aims: Endoscopic evaluation of the excluded stomach after Roux-en-Y gastric bypass surgery for morbid obesity is a challenge, pathological changes that take place in bypassed are unclear. A new double-balloon method evaluating described here. Patients Methods: This enteroscope uses two balloons, one attached to tip endoscope other distal end soft overtube. The procedures were carried out six patients using retrograde route, through end-to-side jejunal anastomosis via...
Background and Study Aims: There have so far been no prospective studies on the value of flexible endoscopy for removing foreign bodies in upper gastrointestinal tract. This study presents a clinical analysis accidents with prospectively evaluates effectiveness them. Patients Methods: A total 105 cases foreign-body ingestion tract were evaluated, 29 (27.6 %) children 76 (72.4 adults. Thirty patients (28.5 had esophageal strictures. Results: Thirty-nine (37.1 consisted food 66 (62.9 not...
The duodenal-jejunal bypass liner (DJBL) is a device that mimics the intestinal portion of gastric surgery and has been shown to improve glucose metabolism rapidly in obese subjects with type 2 diabetes (T2DM). To assess safety DJBL evaluate its potential affect glycemic control beneficially T2DM who were not morbidly obese. Adult men women ≤10 years' duration hemoglobin A1c (HbA1c) ≥7.5% ≤10% having body mass index ≥26 ≤50 kg/m2 enrolled this prospective, 52-week, single-center, open-label...
Objective Endoscopic sphincterotomy (ES) may facilitate insertion of self expandable metal stent (SEMS) and also help avert the development pancreatitis from stent-related occlusion pancreatic duct. On other hand, ES is independently associated with pancreatitis, bleeding, perforation. We evaluated whether before SEMS placement was a greater likelihood migration complications in patients malignant obstruction distal common bile Methods Seventy-four unresectable duct were prospectively...
Objectives The accuracy of endoscopic ultrasound-fine needle aspiration cytology (EUS-FNAC) for the diagnosis pancreatic cancer is suboptimal. Mutational activation kras oncogene almost universally present in tissue. We, therefore, investigated if analysis mutant gene EUS-FNAC aspirates supplements cytopathology adenocarcinoma (PAC). Methods specimens obtained from 74 patients with masses were analyzed presence mutation on codon 12 using polymerase chain reaction-restriction fragment length...
Abstract Aims To report Type 2 diabetes‐related outcomes after the implantation of a duodenal‐jejunal bypass liner device and to investigate role proximal gut exclusion from food in glucose homeostasis using model this device. Methods Sixteen patients with diabetes BMI <36 kg/m were evaluated before 1, 12 52 weeks 26 explantation. Mixed‐meal tolerance tests conducted over period 120 min glucose, insulin C‐peptide levels measured. The Matsuda index homeostatic assessment resistance used...
Abstract Background and study aims Endoscopic removal of biliary stones has high success rates, ranging between 85 % to 95 %. Nevertheless, some may be challenging different endoscopic methods have evolved. Papillary large balloon dilation after sphincterotomy is a widely used technique with rates from 68 90 for larger than 15 mm. Cholangioscopy allows performing lithotripsy under direct visualization, either by laser or electrohydraulic waves, which similar rate (80 – %). However, there no...
