Hysterectomy via transvaginal natural orifice transluminal endoscopic surgery for nonprolapsed uteri

Background Natural orifice transluminal endoscopic surgery has shown its prospection as a minimally invasive endoscopic surgery. This study aimed to examine the safety and feasibility of transvaginal natural orifice transluminal endoscopic hysterectomy (tVNOTEH) for nonprolapsed uteri in the management of benign gynecological diseases. Methods Records were reviewed for the 147 consecutive tVNOTEH procedures between April 2011 and October 2013. Age, body mass index, number of vaginal delivery, and specimen weight were used to select comparable patient who had undergone laparoscopically assisted vaginal hysterectomy (LAVH). Results A total of 512 patients were recruited in this study (147 tVNOTEHs and 365 LAVHs, respectively). These patients were stratified into six subgroups according to the uterine weight and type of hysterectomy. There was no incidence of switching to abdominal laparatomy. Length of operation, estimated blood loss (EBL), requirement of blood transfusion, and length of postoperative stay were significantly greater in the LAVH group than in the tVNOTEH group but total hospital charges were higher in the tVNOTEH group ( p
