This video presents a detailed laparoscopic hysterectomy performed for a patient with Grade IV Deep Infiltrating Endometriosis. The surgeon begins by explaining why comprehensive preoperative imaging is essential and discusses the challenges posed by severe pelvic adhesions that were not identified beforehand. The procedure then walks through retroperitoneal dissection, ureter identification, uterine artery ligation, bowel mobilization, and safe removal of extensive endometriotic disease. Throughout the surgery, the speaker explains the anatomical landmarks, surgical decision-making, and techniques used to avoid injury to vital pelvic structures. The video also discusses strategies to reduce recurrence and emphasizes multidisciplinary planning for advanced endometriosis cases. It serves as an in-depth educational resource for surgeons looking to refine advanced laparoscopic skills.
