Multi-center Prospective Study on E-NOTES for Myomectomy With Traction of Multidirectional Sutures
Study Details
Study Description
Brief Summary
Primary objectives : To investigate technical feasibility and postoperative morbidity after E-NOTES for Myomectomy with Traction of Multidirectional Sutures
Secondary objectives : To investigate postoperative pain after E-NOTES for Myomectomy with Traction of Multidirectional Sutures by clinical variables such as incision size, type of port, size and number of myoma, or operation time.

Detailed Description
-
Leiomyoma is a common benign tumor of the smooth muscle cells of the myometrium.1 It can cause several symptoms such as abnormal vaginal bleeding, pain, or urinary symptoms according to size and location. Steadily, lesser invasive surgeries have been preferred for such benign disease (laparotomy, laparoscopy, and then single-port surgery).2,3
-
However, these minimal approaches, laparoscopic morcellation of preoperatively suspicious leimyoma, have the potential risk of peritoneal seeding of postoperative diagnosed leiomyosarcoma in the pathological examination.4 Currently, safe morcellation is also required during myomectomy while using a lesser invasive surgical approach such as single-port surgery or natural orifice transumbilical endoscopic surgery (NOTES).
-
During single-port surgery or embryonic NOTES (E-NOTES) via an umbilicus, handling of myoma into different directions could be quite a big challenge. Fortunately, myoma is enough hard to pull with string and has a tendency not to rupture during manipulation of these strings.
-
These concepts lead to traction of anchoring sutures during E-NOTES for myomectomy applied in the current case. Safe morcellation could be guaranteed, because direction morcellation via an umbilicus is possible in an endobag.
-
This useful and safe surgical approach needs to be confirmed in multi-centers in terms of feasibility and morbidity.

Outcome Measures
Primary Outcome Measures
- Technical feasibilities and postoperative morbidity after E-NOTES for Myomectomy with Traction of Multidirectional Sutures [Postoperative surveillance including pain evaluation as routine clinical practise for 1 months]
Technical feasibility and postoperative morbidity will be evaluated in terms of overall or institutional conversion rate to convetional multi-port laparoscopy or laparotomy, operation time for each surgical procedures: dissection, morecellation, suturing, and total surgical procedures, complication, change of hemoglobin, and estimated blood loss
Secondary Outcome Measures
- Postoperative pain after E-NOTES for Myomectomy with Traction of Multidirectional Sutures by clinical variables such as incision size, type of port, size and number of myoma, or operation time. [Preoperative and postoperative pain]
Visual analogue scale will be used for pain evaluation: preoperative, postoperative 24 hour, postoperative 48 hour, postoperative 10 day (7 to 10 day), and postoperative 28 day (21 to 35 day).
