Novel technique of extracorporeal intrauterine morcellation after total laparoscopic hysterectomy: Three emblematic case reports

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.

Induction of total laparoscopic hysterectomy adopted the marionette technique in peri-menopausal and post-menopausal CIN3 patients

Objective:When performing cervical conization in post-menopausal cervical intraepithelial neoplasia 3(CIN3)patients,the positive rate of endocervical cone margin and the incidence of postoperative cervical stenosis increase.This study summarized a 4-year experience of total laparoscopic hysterectomy as a treatment option for peri-menopausal and post-menopausal CIN3 patients at a single institution.Furthermore,it shared the refinement strategies used during the surgery.Methods:This study retrospectively analyzed the medical records of CIN3 patient aged45 years and who underwent open or laparoscopic hysterectomy at our institution from January 1,2017 to December 31,2020.Totally,30 CIN3 patients were enrolled and divided into abdominal hysterectomy group and laparoscopic hysterectomy based on surgery method,with 5 patients and 25 patients respectively.Results:Compared to the abdominal hysterectomy group,the perioperative blood loss(20 mL vs.220 mL,p=0.004)was less and the duration of in-hospital stay(7 d vs.11 d,p<0.001)were significantly shorter in the laparoscopic hysterectomy group.However,no significant differences in age at hysterectomy(53 y vs.77 y,p=0.054)and operative time(154.4±27.8 min vs.161.0±62.4 min,p=0.826)were observed between them.Diagnostic conization was performed in advance for 12 patients,and among them,10(83.3%)patients had positive endocervical cone margin.Postoperative intestinal obstructionwas noted in one abdominal hysterectomy patient,no other complications were observed in the remaining patients.Conclusion:Compared to conization,hysterectomy is more invasive;however,it is an acceptable treatment option for peri-menopausal and post-menopausal CIN3 patients.In such cases,opting for total laparoscopic hysterectomy adopted the marionette technique might be preferable because the procedure is less invasive.

Usefulness of Detailed Analysis with Operative Procedure of Total Laparoscopic Hysterectomy (TLH) Done a Single Surgeon, to Master the Surgical Technique of TLH and Gain Higher Proficiency

Objective: To analyze the relationship between the numbers of cases experienced and the operation time for a single surgeon aiming to master the TLH surgical technique. Material and Methods: Retrospective data analysis of women who underwent TLH for benign diseases between April, 2014 and March, 2016 was conducted by a single surgeon in a single hospital (Showa University of Fujigaoka Hospital). We divided the main procedures of the TLH operation into five sections, and measured the time required for each section. These cases were divided into three groups, group 1, 2, and 3. Results: There were 54 cases of TLH over two years for a single surgeon, and 21 cases that included essential operative procedures were divided into three groups of seven cases each. The average duration of the surgery (min.) was 178.3 ± 48.2 in the group 1, 128.3 ± 15.6 in the group 2, and 111.3 ± 15.9 in the group 3. A significant reduction in the required time was observed between group 1, 2, and 3 groups. As the number of cases increased, the operation time became statistically significantly shorter for every section except B and D. The skill growth rate was different at each section. Conclusion: For a single surgeon, as the number of surgical cases increased, we recognized the increased skill with the procedure in every section and the rate of skill growth differed for different sections. The difference of growth rate for each section implied that the number of operative cases required for a surgeon in each section was different.
