BACKGROUND In the presence of a large uterus,total laparoscopic hysterectomy(TLH),always requires morcellation to allow removal of the tissues from the abdominal cavity.However,uncontained morcellation has been scrutinized because of the possible spread of occult leiomyosarcoma.Therefore,in-bag extracorporeal morcellation has been developed.However,tissue containment and extraction are extremely challenging,especially when considering the increasing uterine size to be removed through minimally invasive surgery.CASE SUMMARY Herein,we describe a novel technique for extracorporeal intrauterine morcellation using the uterus outermost layer as a bag to achieve tissue extraction of very large uteri with suspected occult leiomyosarcoma after TLH.The study enrolled patients who were planned for TLH for large uteri(weight>500 g).TLH was performed following the procedure reported in our previous studies.The novel technique has been described step-by-step in a video,which representatively describes the preoperative imaging and morcellation procedure of three very large uteri weighing 1500 g,1700 g,and 3700 g,respectively.The procedures were performed without any complications.The patients had an uneventful postoperative course,and in all cases,the pathology was benign leiomyoma.CONCLUSION Extracorporeal intrauterine morcellation using the uterus outmost layer as a bag was found to be a feasible technique that allows a careful diagnosis and safe removal of suspected occult malignancies.The technique herein presented may be adopted in surgical practice,by adding it to the other available techniques of contained morcellation.It may represent a valid and feasible alternative,especially useful in cases of very large uteri exceeding the capacity of specimen retrieval bags.
