This comprehensive surgical video demonstrates the principles and operative technique of Laparoscopic One Anastomosis Gastric Bypass (OAGB) at World Laparoscopy Hospital. OAGB, also known as mini gastric bypass in some clinical settings, is an established bariatric procedure that combines gastric restriction with intestinal bypass and metabolic effects to support substantial weight reduction in appropriately selected patients.

The procedure begins with laparoscopic access and systematic evaluation of the abdominal cavity. A carefully constructed narrow gastric pouch is created, followed by identification of the appropriate jejunal segment and construction of a single gastrojejunal anastomosis. Every stage requires a clear understanding of gastrointestinal anatomy, appropriate tissue handling, precise stapling and suturing, and careful assessment of the completed reconstruction.

This video provides an educational overview of important steps in OAGB surgery, including patient positioning, trocar placement, creation of the gastric pouch, identification of the biliopancreatic and alimentary limbs, bowel measurement, gastrojejunostomy, and intraoperative assessment. The demonstration also emphasizes the importance of maintaining proper orientation and avoiding tension or twisting of the bowel during reconstruction.

For surgeons learning advanced bariatric procedures, understanding the technical details of OAGB is essential. Proper patient selection, standardized operative technique, appropriate limb length, secure anastomosis, and postoperative monitoring all contribute to safe and effective bariatric care. The video is particularly useful for surgeons, laparoscopic trainees, fellows, residents, and medical professionals who want to expand their knowledge of minimally invasive metabolic surgery.

World Laparoscopy Hospital provides structured education and hands-on training in advanced laparoscopic, robotic, and minimally invasive surgical techniques. Surgical demonstrations such as OAGB help trainees understand how modern bariatric procedures are performed and the technical principles that guide each operative step.
