Timing of LNG-IUD Insertion and Ovarian Cyst Formation

In this prospective observational study, the effect of timing of insertion (early/late follicular; early/late luteal) on ovarian cyst development in women receiving an LNG-IUD will be assessed ultrasonographically at months 0, 3, 6, and 12. Secondary outcomes include cyst size/structure, bleeding pattern, pain, and other adverse events.

A Randomized Controlled Trial Study Comparing Adnexal Surgery by vNOTES or Laparoscopy

The aim with the study is to compare postoperative pain after vNOTES adnexal surgery versus laparoscopic adnexal surgery. Women aged 18 and above with an indication for adnexal surgery for benign gynecological pathology or prophylactic reasons will be able to participate. After surgery the participants will answer a questioner, twice a day in seven days, about postoperative pain and how many units of analgesics they used. Adnexal surgery is one of the most common surgical procedures performed in women and can either be performed to treat pathology as ovarian cysts or prophylactically in case of hereditary genetic alterations. A laparoscopic technique is currently considered as gold standard for adnexal procedures. The latest advancement in minimally invasive surgery is vNOTES (vaginal natural orifice transluminal endoscopy), in which the entrance to the abdomen is performed by an anterior or more commonly posterior colpotomy rather than via the abdominal wall. The NOTABLE trial was a RCT showing that vNOTES adnexectomy was non-inferior to laparoscopy for successful removal of benign adnexa without conversion (Baekelandt). vNOTES adnexectomy had shorter surgical time, less use of analgesics and lower self-assessed VAS scores the first week post-operatively. The aim with our study is to compare postoperative pain after vNOTES versus laparoscopic adnexal surgery.

Comparison Between Electrosurgical Energy and Hemostatic Sealants on Hemostasis in Laparoscopic Ovarian Cystectomy

The aim of this study is to compare between the effect of using electrosurgical energy and hemostatic sealant for hemostasis in laparoscopic cystectomy for ovarian cysts.

A Clinical Study on the Feasibility and Safety of Abdominal Endoscopic Single-port Surgery System to Assist Gynecological Day Surgery

In this study, a prospective study is used to select patients who will undergo intra-abdominal endoscopic single-port surgery system for benign gynecological diseases from February 2025 to December 2026 in the Second Affiliated Hospital of Wenzhou Medical University, including hysterectomy, myomectomy, ovarian cyst removal and adnexectomy. The study will perform statistical analysis to evaluate the feasibility and the main factors affecting the safety of intra-abdominal endoscopic single-port surgery system(SR-ENS-600) used in gynecological day surgery.

Quest to Analyze One Thousand Humans Meditating

This study will be focused on assessing the molecular, physiological, and emotional correlates of an intensive meditation experience in the context of a retreat setting in a large 2000 plus-person cohort comprised of healthy and clinical populations.

MIRRORS-FROZEN - Comparing Open Vs Robotic Surgery in the Management of Women with Complex Pelvic Adnexal Masses ≤ 8cm.

Adnexal masses are growths that can form in the ovaries or fallopian tubes for different reasons, such as hormonal changes, infection, or cancer. These masses may cause pelvic discomfort, pain, constipation, or no symptoms at all. When adnexal masses are found on scans, they are described in a certain way to indicate if they could represent early-stage cancer, and the word "complex" is used to refer to these masses. Surgery is often recommended, where the mass is removed and examined under the microscope during surgery in a process called (frozen section analysis); to determine its true nature. It is still difficult to confirm cancer before surgery, and many of these masses turn out to be benign (not cancerous) or borderline (slow-growing tumours). Currently, doctors use open surgery with a cut from at least the belly button to the pubic bone to remove these masses. Patients with a cancer diagnosis will then have more surgical steps including assessment and sampling of various areas inside the abdomen (known as staging surgery) to see how far the cancer has spread. Recovery after open surgery can be long and painful, with a slow return to normal daily activities. The trial investigators know from practice that robotic surgery has replaced open surgery for most benign adnexal diseases and other types of women's cancers, such as womb cancer. Recovery is quicker, with less pain and blood loss, allowing for a faster return to daily activities. This study, MIRRORS-FROZEN (pilot), compares robotic versus the standard open surgery in managing women with complex adnexal masses of eight centimetres or less. The hope is to decrease the need for open surgery in patients with benign or borderline disease and to assess if robotic surgery has similar, worse, or better outcomes for patients with cancer. MIRRORS-FROZEN is funded by Intuitive Foundation and GRACE Charity. The investigators will establish the feasibility of conducting a large multicentre randomized controlled trial in the future comparing certain cancer outcomes between robotic and open surgery.

Improved Diagnosis of Ovarian Cancer

After implementation of systematic image description of adnexal masses, we aim to improve and evaluate our use of available imaging methods and biomarkers for classifying adnexal masses and distinguishing between benign and malignant adnexal masses in the hands of clinicians in Central Denmark Region. Secondarily, we want to improve our management of adnexal masses by evaluating the complications and longitudinal changes in conservatively managed adnexal masses. Data is registered prospectively but analyzed retrospectively.

Improved Diagnosis of Ovarian Cancer by Use of Circulating Tumor DNA as a Biomarker

This project investigates circulating tumor DNA (ctDNA) in patients with suspected ovarian malignancy. We hypothesize that measurement of ctDNA in women with suspected ovarian cancer can improve the diagnostic efficiency for preoperative differentiation between benign and malignant masses. Specifically, we hope to determine the diagnostic efficiency of ctDNA alone and ctDNA in combination with imaging modalities (ultrasonography, MRI, PET-CT) and CA 125 for preoperative differentiation between benign and malignant adnexal masses. Based on this, we hope to develop an improved diagnostic algorithm. The mutational profile and relation to tumour type, stage, treatment response and prognosis will be explored. Analyses of blood and tissue samples will be used to examine the disease development and biology. Blood samples, tumour tissue and data on imaging modalities as well as CA 125 will be collected prospectively in consecutive women referred to Aarhus University Hospital.
