Embryonic residual cyst

Introduction

Introduction to embryonic residual cysts

Embryonic residual cysts are also called middle renal cysts, ovarian canal cysts, Gartner's cyst. Most believed to be derived from the remains of the kidney tube during the embryonic period, that is, the middle kidney tube remains in the vaginal part before the outer wall reaches the lowermost part of the vagina, the secretion is retained and the cyst is formed; or due to incomplete degradation, part of the cystic expansion Form a cyst.

basic knowledge

Sickness ratio: 0.05%-0.1%

Susceptible people: women

Mode of infection: non-infectious

Complications: tubal adhesions intrauterine adhesions

Pathogen

Causes of embryonic residual cysts

During the abortion operation, the intrauterine embryos were not cleaned and there were residual embryos, which led to the formation of cysts.

Prevention

Embryo-retained cyst prevention

1, should pay attention to hygiene, keep the vulva clean and prevent the invasion of pathogens.

2, the implementation of family planning, the use of contraceptive measures, as far as possible to avoid mechanical damage to the cervix. At the same time, gynecological surgery should be strictly sterile to prevent iatrogenic infections and injuries.

3, to the regular hospital to terminate the pregnancy surgery, pay attention to postoperative review.

4, pay attention to exercise, pay proper attention to nutrition and health, and ensure physical and mental health.

5, regular gynecological examination.

Complication

Embryonic residual cyst complications Complications, tubal adhesions, intrauterine adhesions

Tubal adhesions, intrauterine adhesions.

Symptom

Embryogenic residual cyst symptoms Common symptoms Abdominal pain Lower abdomen bulge

1, vaginal bleeding, increased vaginal discharge, yellowing.

2, paroxysmal abdominal cramps.

Examine

Examination of embryonic residual cysts

1. Ultrasound examination: At present, domestic B-ultrasound examination is more common.

2, hysterosalpingography: ideal uterine angiography can not only show the size of the cyst, and can be positioned.

3, hysteroscopy: hysteroscopy can observe the nature of intrauterine lesions under direct vision, determine the lesion.

4, laparoscopic examination: With the wide application of laparoscopic techniques in obstetrics and gynecology, laparoscopic surgery is not only used as a means of examination, but also often concurrent with surgery, and has received increasing attention.

Diagnosis

Diagnosis and differentiation of embryonic residual cysts

1. Increased menstruation, prolonged menstruation or irregular vaginal bleeding.

2. Gynecological examination can be found that the uterus is enlarged.

3. B-ultrasound can show images of cysts.

Pathological examination of embryonic residual cysts is smooth, lining a single layer of cubic epithelium or pilose columnar epithelium, stratified epithelium can also be seen in some parts of the sac; watery, serous milky white in the sac Liquid, or brown viscous liquid; surrounded by smooth muscles outside the embryonic cyst.
