Filter by:The goal of this observational study is to assess the correlation between the artificial intelligence (AI) derived effective withdrawal time (EWT) during colonoscopy and endoscopists' baseline adenoma detection rate (ADR). The association between the AI derived EWT with ADR during the prospective colonoscopy series would also be determined. The colonoscopy video of participants will be monitored by the AI and the result of EWT will be blinded to the endoscopists
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 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.
Predicting the outcome of pituitary surgery, particularly the risk of complications, is a critical determinant in selecting the appropriate treatment modality for patients. To date, only a limited number of risk factors have been identified for complications following pituitary surgery, including tumor size, younger age, and previous surgical intervention. Furthermore, existing studies have demonstrated that prolactin levels can serve as a surrogate marker for assessing pituitary function, specifically revealing associations between elevated prolactin levels and anterior pituitary insufficiencies. In a retrospective study on the "HYP'OP" cohort, the aim of the study is to identify predictive factors for both surgical outcomes and complications.
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)
The detection of adenomas is the basis for the follow-up of patients with familial adenomatous polyposis, after colectomy, with a remnant rectum or an ileal pouch. The optimal method for the adenomas detection is not defined yet. Despite the proven effectiveness of indigo-carmine in different indications dye chromoendoscopy is not used in a consensual way at the international level. The situation of the ileal pouch is specific as adenomas have a usually flat shape and are much more difficult to identify than in the situation of a remnant rectum, even in the situation of > 5 mm adenomas that should be resected. Our hypothesis is that indigo-carmine can improve adenomas detection, including > 5 mm adenomas, in patients with a an ileal pouch after colectomy improving the effectiveness of surveillance programs and potentially reducing the risk of cancer in this population.
