Active clinical trials for "Adenoma"

Pituitary adenoma can be difficult to cure with approximately a third of patients in contemporary series' undergoing incomplete resection. Over the last decade or so a handful of groups have described the use intraoperative ultrasound to improve resection. Although limited, these proof-of-concept studies suggest intraoperative ultrasound is a safe and effective technological adjunct to transsphenoidal surgery for pituitary adenoma. In this prospective development study 30 adult patients will undergo transsphenoidal surgery for pituitary adenoma with prototype intraoperative ultrasound devices. The primary outcomes will be technical feasibility and device safety. The secondary outcomes will be complete versus incomplete radiological resection, endocrinological remission, the occurrence of postoperative complications, operating time, and length of stay.

This multicenter prospective non-randomized interventional study (clinical trial) that will assess the safety and efficacy of cryoballoon ablation treatment using the C2 Cryoballoon device (Pentax Medical Corporation) as an alternative primary treatment modality for sporadic and familial nonampullary nonpolypoid (flat) duodenal adenomas.

This study is a prospective, single-arm, multi-center, open-label, staged clinical study. Overall Objective: To evaluate the safety and effectiveness of the ELS System in subjects undergoing transanal endoluminal procedures in the rectum and distal colon (up to 17 cm from the anal verge). To validate a program for training surgeons and their teams to successfully use the ELS System.

Initially developed in Japan for the treatment of endemic superficial gastric cancers, endoscopic submucosal dissection (ESD) allows resection of pre-neoplastic and neoplastic lesions of the digestive tract into a single fragment. It allows a perfect pathological analysis, and decreases the rate of recurrence of the adenoma to less than 2% However, this procedure, which is technically more challenging, is also more risky (perforation rate at 4% vs. 1% for WF-EMR) and longer. Submucosal dissection is also more expensive in terms of equipment, but this difference can be offset by the cost of the high number of iterative colonoscopies required in patients who have had endoscopic resection by WF-EMR. Scientific debate is agitating the Western world1,2 and Japanese experts do not perform WF-EMR anymore, whereas no comparative prospective study has compared these two procedures. We therefore propose to compare these two endoscopic resection strategies in terms of recurrence rate at 6 months and to estimate the differential cost-effectiveness and cost-utility ratios over a 36-month time horizon.

This phase II trial studies the how well linaclotide works in treating patients with stages 0-3 colorectal cancer. Linaclotide is a very small protein that binds to receptors on intestinal cells and makes them secrete water and salt.

Single-center, four-arm dual-tandem, randomized, open-label study involving the following devices: The Standard Colonoscope is a high-definition colonoscope employing advanced optical filtering and enhancement techniques - blue light imaging (BLI) and linked color imaging (LCI). CAD-EYE is an artificial intelligence software, used in real-time during the colonoscopy procedure for aiding the identification and characterization of polyps and adenomas. The G-EYE® balloon is a reusable (reprocessable) balloon permanently installed on the distal tip of a standard colonoscope, and is also intended to assist in flattening colonic folds and control the colonoscope's field of view and tip positioning.

The investigatior believe that implementing camera capsule endoscopy as a filter test to colonoscopy will increase screening participation, increase the number of individuals with detected intermediate- high risk adenomas or cancer, reduce the colonoscopy demand and reduce the number of complications.

A Prospective Randomized Comparison of colonoscopy Adenoma Detection Yield of (i) Standard Colonoscopy (SC), (ii) artificial intelligence (Discovery) aided colonoscopy, and (iii) artificial intelligence (Discovery) and permanently mounted balloon (G-EYE®) aided colonoscopy.

This is a prospective single arm single center Phase III study evaluating the ability of 18F-fluorocholine to detect the location of parathyroid adenomas.

The purpose of this clinical trial is to investigate the accuracy of applying three-dimensional ultrasound on thyroid gland patients when determining a gland volume. The method will be compared to conventional b-mode ultrasound where three axis measurements (length, width, and depth) are evaluated in the ellipsoid model. The three dimensional (3D) method is utilizing optical tracking connected to the ultrasound image to form cross-sectional imaging. Patients enrolled in the study are set for complete thyroidectomies enabling a true volume of the gland by water displacement after excision. The aim is to find if this 3D method is more accurate in volume estimation than the ellipsoid model.
