One third of individuals aged >60 years will be diagnosed with at least one renal cyst following abdominal imaging. These cystic lesions are categorized according to the Bosniak classification which categorizes cysts according to their degree of complexity and risk of malignancy. Growing evidence suggests that a significant proportion of Bosniak III and IV cysts are benign and that the malignant ones present low metastatic potential. Since renal surgery carries substantial morbidity (20%) and potential mortality (0.5%), active surveillance has gained attention as a potential tradeoff to surgery to overcome overtreatment. Therefore, prospective studies of long-term follow-up are needed to confirm the oncologic safety of this strategy for patients with Bosniak III/IV cysts. This is an multicenter prospective observational longitudinal study. The main objective is to compare the 5-year follow-up cancer-specific survival between the active surveillance and the surgical groups.
This study is based on pubertal surveillance of fetal ovarian cysts (KOF). Fetal ovarian cysts (KOF) detected during fetal ultrasound examinations occur during the 3rd trimester of pregnancy and are of unknown cause.
The subject will treat 68 patients with symptomatic sacral canal cysts as the research object, and adopt a randomized controlled research method, respectively, using two methods of reinforcement and reconstruction of the nerve root sleeve, sacroplasty and nerve root sleeve plasty, and observed the operation of the patient Complications, preoperative and postoperative short-term and long-term VAS pain scores, JOA neural function scores, and changes in cyst size on imaging examinations, to evaluate the safety of nerve root sleeve reconstruction and sacroplasty in reducing the safety of postoperative cyst recurrence Sex and effectiveness, so as to further improve the surgical treatment of sacral canal cysts, improve the curative effect, and formulate the operation specifications for the treatment of sacral canal cyst
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.
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.
Removing in situ and metastasis lesions completely during gynecological surgery is central to reduce the recurrence and death, and the identification of lesions in traditional gynecological surgery often depends on the experience of surgeons. The identification of nerves is often needed in gynecological surgery, such as the obturator nerves in pelvic lymphadenectomy, and the pelvic autonomic nerves in nerve-sparing radical hysterectomy for cervical cancer. Nerve identification also relies heavily on the experience of surgeons. This project aims to realize the identification of lesions and nerves under the navigation of indocyanine green fluorescent imaging, and evaluate the accuracy of fluorescent imaging of lesions and the effectiveness of nerves identification by near-infrared imaging. This project may reduce the recurrence or death caused by residual lesions and postoperative dysfunction caused by nerves injury, thus, improve the survival rate and quality of life for patients with gynecological diseases.
Background: Ovarian cysts are common in women. The vast majority is benign; yet, ovarian cancer (OC) is seen in 500 women every year in Denmark. OC is often diagnosed in advanced stages, and OC is the fifth most deadly cancer in women in more developed countries. It can be a clinical challenge to distinguish benign ovarian cysts from OC. Currently, the Risk of Malignancy Index (RMI) is used to detect women at high risk of OC in Denmark, however, new methods to correctly differentiate benign ovarian cysts from OC at an early stage is needed. New promising studies suggest an improved diagnostic accuracy by adding the biomarker Human Epididymis Protein 4 (HE4) and systemized ultrasound imaging International Ovarian Tumor Analysis (IOTA). Purpose: The purpose is to evaluate the diagnostic performance of HE4 and IOTA in a Danish clinical setting. Furthermore, to develop an optimized diagnostic algorithm to differentiate ovarian cysts based on a combination of symptoms, biomarkers and IOTA. Methods: The study is a prospective, observational study. Women with ovarian cysts are included from gynecological practitioners and departments in the Capital Region of Denmark. Detailed information on health and symptoms are registered, and the cysts are systematically described by the gynecologist in accordance to the IOTA terminology. HE4 will be analyzed in those women who routinely needs a diagnostic blood test for CA125. Data will be coupled with data from the patient file and Danish Gynecological Cancer Database (DGCD). The diagnostic utility of HE4 and IOTA will be evaluated both alone and in combinations with health information, symptoms, and CA125. The study has been approved by the Regional Committee on Health Research Ethics (H-19021342) and the Data Protection Agency (P-2019-340). Significance: This study establishes a unique database which will form the basis for developing an optimized method for differentiating ovarian cysts, and thus optimize referral and diagnosis.
A child is eligible to participate in this study because she is having surgery on her ovary. The investigators may obtain a sample of any discarded tissue from the surgery for an ovarian tissue library. This study is being conducted to understand how common ovarian conditions effect the number and quality of ovarian follicles and the reproductive potential of the ovary.
An observational prospective study to determine the impact of foam sclerotherapy of large, dominant kidney/liver cysts on quality of life outcomes and kidney/liver cyst volumes at up to 12 months of follow-up in patients with autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (ADPLD).
