Active clinical trials for "Adenoma"

The purpose of the study is to assess whether the AI characterisation system of the CADDIE device improves the endoscopists accuracy in the optical diagnosis of diminutive colorectal polyps in the bowel during colonoscopy. Participants will either have a colonoscopy with the assistance of the CADDIE device characterisation AI system ("intervention group") or have a colonoscopy in line with routine clinical practice i.e., without the CADDIE device characterisation AI system ("control group"). The randomisation method of this trial will allocate enrolled participants to the "intervention" group and to the "control" group by a technique similar to flipping a coin.

The radio-guided technique offers both help with in-vivo identification and ex-vivo confirmation of parathyroid adenoma. In-vivo accuracy is most important but its results are not satisfactory. The aim of this study was to evaluate if there is a beneficial effect of individualized timing of surgery using preoperative multi-phase 99mTc-MIBI single-photon emission computed tomography (SPECT)/CT on in-vivo characteristics of minimally invasive radio-guided parathyroidectomy.

This study planned to investigate the effects of aerobic training combined with strengthening training and yoga on biochemical factors, physical performance and quality of life in people with pituitary adenoma. The hypotheses are; H1: Aerobic training combined with strengthening training is effective on biochemical factors in people with pituitary adenoma. H2: Aerobic training combined with strengthening training is effective on physical performance in people with pituitary adenoma. H3: Aerobic training combined with strengthening training is effective on quality of life in people with pituitary adenoma. H4: Yoga is effective on biochemical factors in people with pituitary adenoma. H5: Yoga is effective on physical performance in people with pituitary adenoma. H6: Yoga is effective on quality of life in people with pituitary adenoma. H7: Aerobic training combined with strengthening training and yoga is effective on biochemical factors, physical performance and quality of life in people with pituitary adenoma.

The goal of this trial is to determine whether use of a Computer Assisted Detection (CADe) programme leads to an increase in ADR for either units or individual colonoscopists, independent of setting or expertise

Polyp size and count determines the follow-up intervals after colonoscopy. However, relying on the endoscopist's optical diagnosis for size estimation has shown considerable variability, leading to erroneous surveillance intervals and increased colorectal cancer risk. This study aims to assess the effectiveness of a new polyp size estimation software, called POSEIDON, which uses the tip of the auxiliary water-jet as reference and is implemented together with the EndoMind polyp detection system.

The purpose of this study is to see if there is benefit in using an IV contrast (sodium fluorescein) called AK-Fluor® to identify nerves during head and neck surgery.

The only known cure for primary hyperparathyroidism is surgical removal of one or more parathyroid glands. Some patients however, do not fulfill criteria for surgery or do not want to undergo a procedure due to fear of the associated risks. Therefore a medical alternative is warranted. This study aims to evaluate the effects of Denosumab alone, and in combination with Cinacalcet, as a medical treatment for patients suffering from primary hyperparathyroidism, with mild osteoporosis. To the best of our knowledge no previously reported randomized controlled trial has investigated the use of denosumab in primary hyperparathyroidism. 60 patients will be enrolled in three different treatment-groups: 20 receiving both Denosumab and Cinacalcet, 20 Denosumab and placebo and 20 placebo and placebo. Patients included do not meet the criteria for, or have no wish for a surgical procedure. By combining the two drugs, this study could possibly contribute to the discovery of a realistic medical alternative to surgery. It is expected that the therapy will be able to both control s-calcium and s-intact parathyroid hormone (iPTH), and simultaneously enhance bone-structure. The therapy thus has the potential of preventing fractures and possibly other long-term effects of primary hyperparathyroidism such as formation of kidney stones, and coronary calcification. Another objective of this project is to investigate whether the combined therapy can facilitate an actual reset of the Calcium-sensing receptor, and thereby de facto cure the disease.

Evaluate the safety and efficacy of the Rezum System for the treatment of BPH

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.

Introduction: The usual surgical technique for large adenomatous tumors and rectal cancer is anterior resection of the rectum or abdominoperineal resection. These techniques are associated with high mortality and morbidity and with genitourinary dysfunctions. To solve these problems, transanal endoscopic microsurgery (TEM) was designed. Through its 3-D vision system using a rectoscope, this procedure allows access to rectal tumors located up to 20 cm from the anal verge. It is associated with minimal morbidity and has few repercussions for anal continence. The use of 2-D high definition cameras and screens obtains images of a similar quality to 3-D images. This means that from the surgical point of view the procedure known as TEO (transanal endoscopic operation) seems as practicable as classic TEM. Main aim: To assess the effectiveness of 2-D high definition vision systems (TEO) versus conventional 3-D (TEM) in endoscopic surgery of rectal tumors, with respect to surgical facility, postoperative morbidity, quality of the surgical specimens, and cost. Design: Prospective, controlled, randomized study of the efficacy of the use of 2-D high definition endoscopic systems versus 3-D (TEM) in transanal endoscopic surgery. Disease studied: Rectal adenomas and adenocarcinomas "in situ" suitable for local surgery. Main variable evaluated: Cost per procedure assuming similar surgical efficacy and equal postoperative morbidity. Study population and total number of patients: Patients diagnosed with rectal tumor treated with curative intent (rectal adenomas and adenocarcinomas "in situ"). The total sample calculated for the trial was 36 patients, 18 in each group (TEO and TEM). Timing and expected finish date: After approval by the CEIC, the expected date for the inclusion of the first patient was August 2010. The study is expected to last 18-24 months.
