Dear Armia Michael,

You need to be more specific about the problem you are searching for.  are you asking about a uterine rupture risk during pregnancy? what was the size of the myoma in the previous myomectomy operation? Was endometrial cavity opened during that surgery?

Pubmed has plenty of resources on the subject.  But you need to be specific as much as possible. 

thanks alot for your answer

I'm writing a case report of female with rupture uterus the during the third trimester . she has history of laproscopic myomectomy for subserous myoma was about 10*7cm 2 years before pregnancy.

all resources I found saying myomectomy for subserous myoma is NOT risk factor for rupture uterusF

In theory it should not happened because you never touch the myometrium in subiserous myomectomy, however and maybe all subserous myomas indeed toch or affect the myometrium.  Report your case!

Interesting case, it would be important to know/report on;

how they removed the subserosal fibroid, did they tie off the base and leave a good nubbin of fibroid tissue or did they shave the myometrium in the process; did they use adhesion prevention techniques or did an adhesion attached to the operative site rent the defect in later pregnancy. Was the original fibroid a solitary lesion or was it a multi-fibroid uterus, and one of the intramural fibroids undergo degeneration in pregnancy (predisposing to rupture). All the best.

Also mention how the tissue defect was closed after the myomectomy in your case report.  What kind of suture was used and how was the closure accomplished? layers of closure and technique.  Try to add high quality pictures to increase your chance of acception. a Series of pictures combined in a single picture showing the preoperative photo, and after the removal of the myoma, and finally the closed  incision on the uterus. 

I can not find any case reports about this

The incidence of uterine rupture after laparoscopic myomectomy is generally low, in the most reported series under or about 1%. One should keep in mind that - except of pedunculated myomas - also in cases of subserous myomas, their surgical removal will result in a defect of the myometrium.

The most important protective factors seem to be suturing the myometrium and cautious use of diathermy.  In the recent review of Koo et al (2016) 2 out of 3 uterine ruptures occurred in patients previously operated because of subserous myomas.
