About this study
Official title: Effect of 27-Inch and 55-Inch Endoscopic Imaging Monitors on Surgical and Postoperative Outcomes in Endometrial Cancer Surgery: A Randomized Controlled Trial
This study will compare the use of 27-inch and 55-inch endoscopic imaging monitors during minimally invasive surgery for women with endometrial cancer. Participants will be randomly assigned to one of the two monitor groups. All participants will undergo the same standard surgical procedure; only the monitor size used during surgery will differ. The main question is whether monitor size affects total operative time. The study will also evaluate sentinel lymph node dissection time, blood count changes, complications, infections, hospital stay, and drain-related outcomes during the first 30 days after surgery.
Read the detailed description
This is a single-center, prospective, randomized, parallel-group clinical study designed to evaluate whether endoscopic imaging monitor size affects surgical and early postoperative outcomes in minimally invasive endometrial cancer surgery. Eligible adult women with histologically diagnosed endometrial cancer who are scheduled for total laparoscopic hysterectomy with bilateral salpingectomy or salpingo-oophorectomy and bilateral sentinel lymph node dissection will be enrolled after informed consent.
Participants will be randomly assigned in a 1:1 ratio to surgery using either a 27-inch endoscopic imaging monitor or a 55-inch endoscopic imaging monitor. Both monitor systems are standard surgical imaging equipment used in routine clinical practice. The surgical procedure, operative technique, energy devices, sentinel lymph node mapping approach, and postoperative care will be standardized across both groups. No additional invasive procedure, investigational drug, biologic product, or experimental treatment will be used as part of this study.
The primary outcome measure is total operative time, defined as the time from entry of the laparoscopic optic into the abdomen after trocar placement to completion of surgery. Secondary outcomes include bilateral pelvic sentinel lymph node dissection time, number of right and left sentinel lymph nodes removed, hemoglobin and hematocrit decrease, blood transfusion requirement, intraoperative complications, postoperative complications within 30 days, postoperative infections within 30 days, Clavien-Dindo complication grade, length of hospital stay, drain requirement, and postoperative day of drain removal if a drain is placed.
Participants will be followed during hospitalization and at postoperative day 7-10 and day 30 visits. The study aims to determine whether monitor size has a measurable effect on operative performance and early postoperative outcomes in a standardized minimally invasive surgical setting.

Questions about this trial
What is this clinical trial studying?
A study testing 27-Inch Endoscopic Imaging Monitor and 55-Inch Endoscopic Imaging Monitor in people with Endometrial Cancer, run by Metehan Uzundal at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Metehan Uzundal, MD (+90 541 291 23 88, metehan_uzndl@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Total Operative Time (time frame: During surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07882277, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
