Since then, indications for laparoscopic surgery are rising. Comprehensive staging of endometrial cancer guides the use of post-operative adjuvant therapy.Benefits of a laparoscopic approach are shorter hospitalisations, lower blood loss, faster postoperative recovery.Methodology Safe , step by step method of total hysterectomy and bilateral salpingo-oophorectomy with pelvic and para-aortic lymph node dissection. Dissection and visualisation of anatomical landmarks as safest , most reliable method of performing laparoscopic surgery.Result(s)*54 year old woman with endometrial cancer G2 FIGO IB was qualified for laparoscopic surgery. Total hysterectomy and bilateral salpingo-oophorectomy with pelvic and para-aortic lymph node was performed. Patient was discharged from hospital after 3 days in good condition, with no significant blood loss or other complications.Final histopathology result : TIBN0M0 , 68 lymph nodes from paraaortic and pelvic lyphadectomy.LVSI negativeConclusion*We are convinced that our approach to laparoscopic total hysterectomy with lymphadenectomy is safe and repetitive. By dissection and visualisation key anatomical landmarks we can avoid complications such as bleeding , damage to the ureters, nerves and vessels.
