Filter by:KRANIOPHARYNGEOM Registry 2019 will prospectively collect and descriptively analyse data on diagnostics, treatment, and follow-up of patients with craniopharyngioma. In continuation of preceding studies also patients with xanthogranuloma, meningioma, pituitary adenoma, prolactinoma and cystic intracranial malformations will be registered.
Comparing the complete resection rate and subsequent adenoma recurrence rate at surveillance colonoscopy of 15-40mm laterally spreading adenomas for conventional EMR vs. cold snare EMR.
Comparison of the number of adenomas missed by the first exploration of the right colon by LCI (linked color imaging) or by white light during a colonoscopy, according to the order of randomization.
During standard colonoscopy a substantial number of colorectal polyps may be missed. Previous studies have found a 12-28% of miss rate for all polyps, a 31% for hyperplastic polyps and 6-27% for adenomas. In this study it is tested whether a retro viewing endoscope can detect more colorectal polyps in comparisson to standard forward viewing endoscopy. Further, ppolyps detected, mean adenomas per Patient and withdrawal time are recorded.
Colonoscopy is a key technique in the detection and diagnosis of lower gastrointestinal diseases. High quality endoscopy results in better disease outcomes. However, the operant level of different endoscopists is significantly different.This study aims to construct a real-time quality monitoring system based on computer vision, named Endo.Angel, which is used to monitor the velocity of insertion of the endoscope, record the time of insertion and withdrawal of the endoscope, and remind endoscopists of the blind areas caused by intestinal segment slipping.
The study population consists of patients who undergo resection for somatostatin receptor-positive (SSTR-positive) CNS tumors, focusing on meningioma, and including esthesioneuroblastoma, hemangioblastoma, medulloblastoma, paraganglioma, pituitary adenoma, and SSTR-positive systemic cancers metastatic to the brain, such as small cell carcinoma of the lung. The study indication is to determine the diagnostic utility of 68Ga-DOTATATE PET/MRI in the diagnosis and management of patients with SSTR-positive CNS tumors, specifically whether 68Ga-DOTATATE PET/MRI demonstrates utility distinguishing between tumor recurrence and post-treatment change. To date, the utility of Ga-68-DOTATATE PET/MRI in meningioma has not been explored. Investigators have over the past 3 months been able to accrue the largest case series of presently 12 patients in whom Ga-68-DOTATATE PET/MRI demonstrated utility in the assessment of meningioma, including assessment for postsurgical/postradiation recurrence, detection of additional lesions not visualized on MRI alone, and evaluation of osseous invasion. Based on this initial experience, investigators intend to study the impact of Ga-68-DOTATATE PET/MRI in the assessment of the extent of residual tumor in patients status post meningioma resection, specifically in patients in whom tumor location limits resectability, patients with World Health Organization (WHO) grade II/III disease, and patients with history of stereotactic radiosurgery (SRS) who develop postradiation change.
A multi-center randomized controlled trial in only 24 patients showed a significant reduction of the recurrence rate by treatment of the normal appearing perimeter of the EMR defect using the argon plasma coagulator (2). A recent non-randomized trial suggested a substantial reduction by treatment of the perimeter with the snare tip in the soft coagulation mode (3).
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.
Pituitary adenomas are usually benign monoclonal neoplasms caused by a mixture of pituicyte alterations together with a changed endocrine and paracrine regulatory milieu. Thus, it can cause serious health problems such as abnormal target organ function, pain, disability and even death. In clinical practice, we found many patients with pituitary adenomas are usually accompanied by hyperlipidemia, which is the main cause of cardiovascular diseases. However, it has been unclear if there is an association between pituitary adenomas and serum lipid profile. In the present study, we aim to focus on the patients with pituitary adenomas and their lipid profile before and after operation including first occurrence and recurrence.
Endoscopic Mucosal Resection (EMR) is the current standard for effective endoscopic resection of such colon adenomas. If resection is possible in one piece (so-called "en bloc" resection) then recurrence rates are low. However, most non-pedunculated polyps >2 cm are removed in pieces ("piece-meal" resection) which leads to disease recurrence rates between 12-30%. In the March 2019 issue of Gastroenterology Bourke et al. presented that post-EMR ablation of the resection margins using soft coagulation with the tip of a resection snare reduces adenoma recurrence to 5% compared to 21% recurrence found in the control group. Hybrid Argon Plasma Coagulation (h-APC) combines an ablation technique (APC) with the option for submucosal saline injection using a high-pressure water jet. The technique allows to lift of dysplastic epithelium thus creating a safety cushion under the mucosa is lifted with a saline injection and then to ablate larger areas more thoroughly and with a higher energy setting, with a low risk for side effects or complications.
