Filter by:Pheochromocytomas are tumors of the adrenal gland that develop from cells producing adrenaline and noradrenaline. Consequently, intraoperative blood pressure variations (hypertensive and hypotensive episodes) are characteristic of pheochromocytoma surgery, when these tumors are removed. However, recommendations for the management of these tumors are based on data essentially dating from the 1960s-1990s. Since then, anesthesia and surgery for patients with pheochromocytoma have evolved considerably, and have become more effective with time. In these circumstances, a review of the current situation is necessary. The aim of this study is to investigate the intraoperative hemodynamic changes observed in patients undergoing adrenalectomy for pheochromocytoma, comparing them with the hemodynamic profile observed in patients undergoing adrenal surgery for a pathology other than pheochromocytoma (control group).
The goal of this multicenter, observational, analytic, randomized clinical trial is to analyze the laparoscopic and robot-assisted method in the surgical treatment of patients with adrenal diseases. The main question it aims to answer are: 1. to find the superiority of one the the surgical method mentioned above 2. to compare the quality of life in patients with adrenal mass before surgery and after laparoscopic or robotic-assisted adrenalectomy.
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.
As the clinical manifestations of pituitary neuroendocrine tumors vary greatly, 2.7-15% of them are resistant to conventional treatments such as surgery, drug therapy and radiotherapy, and often relapse or regrow in the early postoperative period, which is invasive and has a poor prognosis. Therefore, it is important to find imaging, histological or serum molecular markers for early prediction of the invasiveness and clinical prognosis of pituitary neuroendocrine tumors. The aim of this study is to observe the changes of biomarkers and imaging features in serum or tissues of pituitary neuroendocrine tumors during the course of disease and treatment, and to explore the biomarkers and imaging features that can predict the proliferation, progression and recurrence risk of pituitary neuroendocrine tumors after medical or surgical treatment.
The purpose of this study is to retrospectively and prospectively analyze the efficacy and safety of ultrasound-guided radiofrequency ablation and laparoscopic adrenalectomy in the treatment of aldosterone-producing adenoma (APA). It is planned to retrospectively collect 30 patients with adrenal radiofrequency ablation for APA and 15 patients with age - and sex-matched laparoscopic adrenalectomy for APA in our hospital from January 2020 to June 2024, and continue to follow up for 3 years.
The study involves the planned use of a new microwave-based device during colonoscopy procedures in 50 patients to assess the performance and safety of its use for detection of colorectal polyps and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies (including phantom studies, an ex vivo study with human tissues, and an in vivo study with porcine model) and in a pilot study in humans (NCT05477836)
A randomized controlled crossover study to determine if narrow band imaging or white light endoscopy is superior in detecting right colonic polyps in average risk subjects undergoing screening colonoscopy
The aim of the project is to determine whether nasal inspiratory peak flow is sufficient for preoperative and postoperative measurement of nasal patency compared to rhinomanometry.
Prostate adenoma management includes, if necessary, surgical treatments: resection or vaporization by endoscopy or by open surgery in case of a very large prostate. Laser technology is a curative treatment for prostate adenoma. The minimum duration of hospitalization, in the context of enucleation prostatic endoscopy by laser, is estimated at 48 hours. The Union Clinique has developed an improved rehabilitation care pathway reducing hospitalization duration to 24 hours (one night hospitalization). This care pathway involves patient as an actor in its care but also health professionals, in particular nurses. This study is based on the hypothesis that the model developed by the Union Clinique can be translated to other healthcare establishments and that home return supervized by nurses allows reducing hospital stay length without increasing the risk of serious complications for patients
This study proposes the use of a well-established PET isotope, Fluorine-18 (18F), bound to Choline, for a prospective single-center, single-arm study for participants with suspected parathyroid adenoma and negative or equivocal standard of care 99mTc Sestamibi SPECT/CT
