Endoscopic ultrasound (EUS)-guided sampling is a safe and reliable method for obtaining pathological results of gastrointestinal and adjacent gastrointestinal lesions. Some colon lesions are located in the muscular layer or even in the serosa beneath the mucosa, so conventional colonoscopy with forceps biopsy is often negative. In patients with colon cancer, forceps biopsy during colonoscopy is the current standard diagnostic modality. However, there are cases that are difficult to confirm with forceps biopsy, such as stenosing tumors, or those originating from deep layers. Endoscopic ultrasound (EUS)-guided fine needle biopsy (FNB) is a useful alternative for diagnosis in these cases. We present the successful case of a 62-year-old male with a history of progressive weight loss and a colonic mass at the splenic flexure, whose colonoscopy was unsuccessful, therefore a FNB puncture by EUS...

Introduction: Colonoscopy is the standard method for colorectal cancer diagnosis. Despite the use of multiple devices, polyp and adenoma detection results have been inconsistent. Objectives: The main aim of this research is to determine if there have been differences between conventional colonoscopy (CC) and cap-assisted colonoscopy (CAC) in the diagnosis performance to detect adenomas. Materials and methods: This is a prospective randomized clinical trial that compares the diagnostic performance of CC and CAC in detecting adenomas in a public reference hospital. Results: We randomly assigned 131 patients to either CC (n=64) or CAC (n=67). Cap-assisted colonoscopy was associated with shorter cecal intubation times (6 min vs. 7,5 min, p=0.005) and a higher chance of intubating the ileum (RR = 1.62; 1.21-2.17). There was no statistical difference in the adenoma detection rates (RR: 1.62; 1...
