70. Incise skin along Langer lines for secondary ports x3
71. Insert lateral ports (5mm x2 at LIF and RIF) at position of snuff box which is about 8cm from umbilicus    
72. Insert 10mm port at 5cm above suprapubic
73. All ports should be inserted perpendicular to the abdomen

The Task is an attempt to clarify the current role of vaginal and laparoscopic approaches in case of hysterectomy for benign pathologies. so thanks Dr Tran Tuyet Thi NGUYEN for these Task

laparoscopic hysterectomy is to be preferred to abdominal hysterectomy.
