Filter by:Little is known about the prevalence of small bowel polyps in patients with sporadic Duodenal/Ampullary polyps. The investigators aim to investigate the prevalence of small bowel polyps in patients with sporadic (ie not related to FAP or PJS) duodenal/ampullary adenomas by performing small bowel capsule endoscopy and comparing the results to those acquired from a control cohort undergoing VCE for accepted indication at our centre.
The study aim was to investigate the efficacy and safety of Osilodrostat in patients with Cushing's syndrome due to causes other than Cushing's disease in Japan.
The rationale for the proposed pilot study is to investigate the ability of PET-CT with F18-choline to detect and locate the parathyroid adenoma in patients with primary hyperparathyroidism and negative or non-contributory MIBI (Tc-99m sestamibi) and cervical ultrasound, in order to avoid unnecessary bilateral cervical exploration.
Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide. The cumulative risk of developing CRC is about 6% lifelong. The benefit of screening colonoscopy depends on the detection and removal of all adenomas, however, some of these may be difficult to detect. The "endocuff" (EC) is a polymer sleeve which joins the tip of the colonoscope to improve the image viewing of the mucosa during colonoscopy procedure. There is insufficient evidence of the usefulness of endocuf
This observational study tests the hypothesis that endogenous aldosterone impairs insulin secretion and insulin sensitivity in subjects with primary aldosteronism.
The purpose of this research study is to compare the extent of resection (EOR) in patients with nonfunctioning pituitary adenomas undergoing transsphenoidal surgery using a microsurgical technique to those patients who have undergone surgery with a fully endoscopic technique. Another goal is to compare surgical complications, endocrine outcomes, visual outcomes, length of surgery, length of hospital stay, and readmission rates between the two transsphenoidal surgery techniques. This is an observational data collection study with no experimental procedures or experimental medicines. Endonasal transsphenoidal removal of a pituitary tumor is a unique procedure and there is little information comparing the two surgical techniques.
Adenomatous lesions of the colon are premalignant lesions which have the potential to develop cancer. Therefore adenomas should be resected endoscopically (endo- mucosa resection, EMR). EMR is conducted after submucosal injection of saline which allows to lift the desired lesion prior to resection. In some cases EMR is complicated due to incomplete or failed lifting after the injection of saline. This so- called "non- lifting" sign is a predictor for malignancy of the lesion. Difficult- to- lift polyps are also difficult- to- resect. A higher proportion of these lesions fail to be resected completely using the EMR technique. Alternatively, an over- the- scope full- thickness resection device (FTRD) can be used in order to resect colonic lesions. The FTRD technique has been described elsewhere (Schmidt et al. Gastroenterology 2014; 147: 740-742.e2). No comparative data exists until now on the performance of FTRD resection compared to standard EMR resection of difficult- to- resect colon adenomas. In this study the investigators aim to compare the success of FTRD versus EMR of difficult- to- resect adenomatous lesions (≤ 20 mm).
The study is aimed to determine the potential of volatile marker testing for identification of gastrointestinal cancers (in particular - colorectal and gastric cancers), the related precancerous lesions in the stomach and colon. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.
Comparison of Endocuff-assisted, Cap-assisted and Standard colonoscopy for assessment of the adenoma detection rate (ADR)
A patient referred to have a lesion in the stomach removed. The aims of this study are to collect information on the technique of endoscopic removal of such lesions. By collecting information on a large number of patients undergoing this procedure the investigators can determine the best ways of diagnosing and removing these lesions safely and effectively.
