Filter by:With our retrospective study the investigators show the limitations of the posterior retroperitoneal adrenalectomy by analyzing anatomical parameters. The investigators compared the data from one patient who underwent a conversion with 13 patients without a conversion. Furthermore, they explored the influence of these parameters on the operation time and excluded the patient who had a conversion from this analysis. The investigators hypothesize that by determining anatomical characteristics on cross-sectional imaging (CT or MRI), they can show the limitations of the posterior retroperitoneal adrenalectomy to prevent patients from being converted to lateral transperitoneal adrenalectomy.
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.
The investigators hypothesize that positron emission tomography with fluorocholline (F18-choline PET) will reduce the proportion of unnecessary invasive surgery decisions and that the higher cost of positron emission tomography versus MIBI scintigraphy (Tc99m-sestaMIBI ) will be offset by lower cost in terms of type. surgery performed wisely and 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.
A prospective database of consecutive patients with hyperparathyroidism subject to surgery is created. Preoperative workup and operative findings are recorded in this registry to allow comprehensive analysis.
10% of patients with hypertension potentially have the treatable condition - primary aldosteronism. Primary aldosteronism (PA) is caused by either bilateral adrenal disease (~40%), managed with lifelong medications; or unilateral disease (~60%), cured with laparoscopic surgery (adrenalectomy). Unfortunately, many patients with curable hypertension remain undiagnosed and consequently develop cardiac disease and strokes. The difficulty with identifying curable unilateral disease is due to adrenal vein sampling (AVS): an invasive, and technically-difficult procedure, with inconclusive results in 50% of patients. An alternative novel imaging, 11C-metomidate Positron emission tomography-computed tomography (PET-CT), can detect adrenal tumors, and concurrently confirm their over-activity. It is non-invasive, non-operator-dependent, and can identify more patients with curable hypertension. Investigators hypothesize that 11C-metomidate PET-CT can accurately identify patients with surgically-curable unilateral adrenal disease among hypertensive Asians with primary aldosteronism.
This is a single centre, non-randomized, tandem colonoscopy trial of the NISInspire-C System, followed immediately by a conventional colonoscope (CC). Each trial subject will undergo colonoscopy using the NISInspire-C system, followed immediately by CC. The purpose of this study is to obtain observational data on the safety profile, feasibility and usability of the NISInspire-C System in performing diagnostic colonoscopy in human subjects. The level of procedural pain experienced by subjects will also be explored.
In recent years, with the continuous development of artificial intelligence, automatic polyp detection systems have shown its potential in increasing the colorectal lesions. Yet, whether this system can increase polyp and adenoma detection rates in the real clinical setting is still need to be proved. The primary objective of this study is to examine whether a combination of colonoscopy and a deep learning-based automatic polyp detection system is a feasible way to increase adenoma detection rate compared to standard colonoscopy.
