Comparing 2D 4K and 3D HD imaging in bariatric surgery

Comparison of 2D 4K vs. 3D HD Laparoscopic Imaging Systems in Bariatric Surgery: a Randomized Controlled Prospective Trial

Not applicable Interventional Clarunis - Universitäres Bauchzentrum Basel · NCT05895058

This study is testing whether using 2D 4K or 3D HD imaging during gastric bypass surgery helps patients recover faster and improves the surgery's success.

What this trial studies

This clinical trial aims to compare the effectiveness of two different imaging systems, 2D 4K and 3D HD, during gastric bypass surgery. Laparoscopy is a crucial technique in modern surgery, and the choice of imaging system can significantly impact surgical outcomes such as operation time, precision, and recovery. The study will evaluate how these two systems perform in a clinical setting, focusing on metrics like operation duration and patient recovery. By addressing the lack of comparative studies in this area, the trial seeks to provide valuable insights into the optimal imaging technology for bariatric procedures.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 with a BMI greater than 35 who have not achieved weight loss through conservative dieting for two years.

Not a fit: Patients with a BMI over 50, serious underlying health conditions, or those who do not meet the criteria for gastric bypass will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and faster recovery times for patients undergoing gastric bypass surgery.

How similar studies have performed: While there have been studies showing benefits of 3D systems over 2D, the comparison between 2D 4K and 3D HD systems is novel and has not been extensively tested.
