Active clinical trials for "Cysts"

This is a prospective, cohort, randomized clinical trial examining the effect of simple renal cysts on renal function.

Observational study on the treatment of pilonidal cyst with Holmium laser. Single-centre retrospective study of medical data from patients' medical records

The aim of this study is to investigate if inexpensive, readily available and portable wireless ultrasound devices can detect ganglion cysts of the wrist and hand in compare to a cart-based ultrasound device before surgery.

Benign ovarian cysts are frequent during women's life. They are diagnosed with pelvic pain or fortuitously during an ultra-sonographic exam. In case of persistence,a surgery will be necessary to identify the nature of the cyst and assess its benignity. In some case, cysts are recurrent and multiple surgeries are needed leading to a significant risk of ovarian damage by follicular depletion. Oocyte cryopreservation is no longer considered as an experimental technique of Fertility Preservation since 2013 as it has been recognized to be efficient and safe. According to reproductive medicine scientific committees and the French ethic law, fertility preservation has to be proposed in every situation of infertility risk. To date, there is no cohort study dedicated to fertility preservation by oocyte freezing in this specific subgroup of patients. The purpose of the study is to prospectively evaluate the oocyte number and quality after controlled ovarian hyperstimulation in patients with recurrent ovarian cysts.

The project aims at analysing prognostic and predictive factors involved in diagnostics and surgical treatment of cysts and tumors in the pancreas and periampullary region using both clinical data and blood and tissue samples for biomarker development and validation.

Cystic enucleation is one of the most common conservative surgeries in gynecology; it is commonly performed by a minimally invasive approach such as laparoscopy. A high percentage of these surgeries (6-88 % of cases) are complicated by the cystic rupture with intra-abdominal spillage of its contents (spillage). This occurrence affects the surgical and prognostic outcome by lengthening the time of surgery, increasing the risk of postoperative infection or granulomatous peritonitis, of possible second manifestation of the pathology (example: endometriosis), and in the case of neoformation of a carcinomatous nature by leading to an increase in the stage of disease, exposing patients to a prognostic disadvantage and the need for adjuvant treatments also avoidable. In addition, the previous spillage may be associated with the adherent syndrome with repercussions on patients' morbidity and fertility. For these reasons, it is crucial to optimize the selection of patients who are candidates for cystic enucleation. The present study aims to evaluate a series of ultrasound, medical history, and surgical-preoperative parameters to develop a predictive score for the risk of spillage during laparoscopic surgery. Prospective Observational Study. The study aims to enroll 156 patients.

Choledochal cysts are congenital cystic dilatations of the intra and/or extrahepatic bile duct. They have been considered a rare entity of the child population. Globally, they account for 1% of all biliary pathology benign, with a clearly higher incidence in Asian countries (1/5,000 in China, 1/1,000 in Japan, compared to 1/100,000-150,000 in Western countries). However, the number of adults diagnosed in recent years has increased by up to 70% due to improvements in imaging tests. Currently, the common bile duct malformation is considered a premalignant entity: although the data are not very precise, it is estimated that between 2.6% and 26% of patients diagnosed choledochal cyst, will develop cholangiocarcinoma. In this sense, we must bear in mind that most of the published literature is of Asian origin, where the rate of cholangiocarcinoma is 0.1-71/100,000 compared to 0.1-1.8/100,000 in Europe or 0.6-1/100,000 in the USA. The most used classification to differentiate the types of cysts is that of Todani. Following this classification, we would find a higher rate of malignancy on types I and IV. The recommendations found in the literature refer to the need for surgical intervention for choledochal cysts due to their high rate of malignancy. These recommendations are based on studies conducted in a symptomatic Asian population. We do not usually find in therapeutic algorithms the inclusion of various factors that could be involved in the development of malignancy such as episodes of cholangitis, presence of anomaly in the pancreatobiliary junction, presence of lithiasis in cystic dilatation, etc. Some surveys carried out among the scientific population reflect a lack of consensus on its management: in the same clinical situation, different surgery units specialized in hepatobiliary-pancreatic pathology would act in the opposite way (specifically surgical versus conservative treatment). Bile duct resection is not without complications, both short-term and long-term. Therefore, the patient's symptoms, age or comorbidities can play an important role in decision-making in the treatment of this pathology. This nationwide multicenter retrospective observational study aims to determine the clinical situation of this rare pathology in a Western environment. A retrospective analysis of patients diagnosed with choledochal cyst in the period between 2000 and 2020 is proposed. Demographic variables, risk factors for cholangiocarcinoma, symptoms associated with the cyst and its characteristics, diagnostic method, type of treatment, complications will be analyzed. Malignancy, time, and follow-up method will also be discussed. This study will attempt to answer questions about the incidence of choledochal cysts in our environment, their association with cholangiocarcinoma, the associated morbidity and mortality, as well as the therapeutic and follow-up attitudes adopted in the face of this rare pathology.

The main objective of the study is to compare the diagnostic accuracy of intra-cystic fluid DNA molecular analysis to standard diagnostics. The secondary objective of the study is to evaluate the feasibility of intra-cystic fluid DNA molecular analysis.

Pancreatic cysts are found incidentally on 15-50% of CT and MRIs for all indications and their prevalence is increasing. Many of these cysts may be precursors to pancreatic cancer, and thus pose a substantial risk, however, the vast majority are benign. Increased detection of pancreatic cysts provides an opportunity to diagnose pancreatic malignancy at an early, curable stage yet also increases the potential to over-treat clinically insignificant lesions. This presents a clinical challenge to prevent unnecessary resection of indolent disease, with associated risks of infections, bleeding, diabetes, and costly disability. Unfortunately, there is little information on the epidemiology and natural history of pancreatic cysts to help guide management.
