Abstract Background Current guidelines suggest that routine biopsy of post-endoscopic mucosal resection (EMR) scars can be abandoned, provided a standardized imaging protocol with virtual chromoendoscopy is used. However, few studies have examined the accuracy advanced endoscopic imaging, such as narrow-band (NBI) vs. white-light endoscopy (WLE) for prediction histological recurrence. We aimed to assess whether NBI superior WLE and one or both techniques replace biopsies. Methods The study...
Hyperplastic polyps represent 30-93% of all gastric epithelial polyps. They are generally detected as innocuous incidental findings; however, they have a risk neoplastic transformation and recurrence. Frequency factors for recurrence not well established fields ongoing interest. This study aims to evaluate the frequency identify change hyperplastic (GHP).A single-centre retrospective cohort including consecutive patients who underwent endoscopic resection GHP from January 2009 June 2020....
Colonic lipomas are common mesenchymal tumours. They usually asymptomatic and incidentally diagnosed during endoscopic or radiological examinations. Taking into account their typical features benign nature, tissue sampling, resection follow-up generally not required.A 61-year-old woman with poor surgical fitness presented colonic subocclusion lower gastrointestinal bleeding. A colonoscopy performed 1 month earlier showed a large polypoid lesion necrotic ulcerated areas occupying the lumen of...
The incidence of rectal neuroendocrine tumors (r-NETs) is increasing, and most small r-NETs can be treated endoscopically. optimal endoscopic approach still debatable. Conventional mucosal resection (EMR) leads to frequent incomplete resection. Endoscopic submucosal dissection (ESD) allows higher complete rates but also associated with complication rates. According some studies, cap-assisted EMR (EMR-C) an effective safe alternative for r-NETs.This study aimed evaluate the efficacy safety...
<b><i>Introduction:</i></b> Current guidelines suggest adding oral simethicone to bowel preparation for colonoscopy. However, its effect on key quality indicators screening colonoscopy remains unclear. The primary aim was assess the rate of adequate in split-dose high-volume polyethylene glycol (PEG), with or without simethicone. <b><i>Methods:</i></b> This is an endoscopist-blinded, randomized controlled trial, including patients scheduled...
A 79-year-old man with alcoholic liver cirrhosis without regular medical follow-up, presented at the emergency room hematemesis. An upper endoscopy revealed a varix anterior wall of bulb red wale sign, indicating recent bleeding. injection N-butyl-2 cyanoacrylate plus metacryloxisulfolane was successfully performed. The abdominal computed tomography angiography scan 29x26-mm nodule consistent hepatocellular carcinoma (HCC), tumoral portal vein thrombosis (and communicating collateral from...
A 73-year-old woman presented at Gyneacology Consultation with vaginal sensation of a lump. Physical examination revealed exophytic lesion 3 cm located the right inner lip. The was biopsied and histologic infiltration by mucinous adenocarcinoma. Immunohistochemical study suggested diagnosis colorectal aetiology. subsequent colonoscopy demonstrated an ulcerated circumferential 8 from anal verge Additional staging examinations pulmonary metastasis patient diagnosed cancer stage IV. She...
We report the case of a 69-year-old male with relevant alcohol consumption and history prostate cancer who underwent screening upper gastrointestinal endoscopy colonoscopy. The revealed an ulcerated mass in middle esophagus occupying half circumference. Histologic examination was compatible squamous cell carcinoma. Staging endoscopic ultrasound computed tomography neck, chest abdomen consistent T3N1M0.
An 18-year-old woman presented with progressive oesophageal dysphagia, weight loss and night sweats over a 6-month period. Oesophagogastroduodenoscopy revealed diffuse luminal narrowing normal mucosa, whose biopsies were inconclusive. A cervical thoracic CT scan showed thickening of the upper oesophagus, densification mediastinal fat, several adenopathies 4.3×2.4 cm mass infiltrative appearance heterogeneous enhancement in right paravertebral location. Positron emission tomography-CT marked...
