Method for treating congenital nonvagina through improved sigmoid colon vaginoplasty

Abstract

The invention discloses a method for treating congenital nonvagina by improved sigmoid colon vaginoplasty, which is characterized by comprising the following operation steps: S1, preoperative preparation: preparing intestinal tracts of patients in three days before the operation by using metronidazole for oral administration, preparing full intestinal tracts by using fluid in one day before the operation, and cleaning and enema before and after the operation and in the morning of the same day of the operation; and 200 metronidazole liquid is used for retention enema. According to the method, through preoperative preparation, a measurement method of intestinal canal cutting length, intestinal canal cutting, vaginal cavity formation, intestinal canal underneath arrangement and fixation, and postoperative management, a treatment method of too short colon sigmoid mesangial and a reconstructed vagina peculiar smell prevention treatment are matched, and due to the fact that the anatomical part where the colon sigmoid is located is good for dissection, the colon sigmoid is loose enough when used in the operation; a plurality of bent blood vessels are supplied from the submesenteric artery, so that a section of tissue with proper length and rich in blood supply can be cut out, thus to function like a normal vagina, and the secretion volume of the intestinal canal is moderate, so that the perineal skin cannot be wetted.

Description

technical field

[0001] The invention relates to the technical field of sigmoid colon substituting vaginoplasty, in particular to a method for treating congenital absence of vagina by improving sigmoid colon substituting vaginoplasty. Background technique

[0002] Clinically, 80% to 90% of congenital anomalies without a vagina belong to Mayer Rokitansky KusterHauser syndrome (MRKH syndrome), that is, the uterus and vagina are absent, while the fallopian tubes and ovaries develop normally. Absence of vagina and uterus, but normal development of ovaries and fallopian tubes, some patients with bilateral or unilateral renal hypoplasia, mild deafness, heart disease, etc. , and its incidence rate is about 1 / 4000~1 / 5000[1].

[0003] Among them, 10% of patients with congenital vaginal absence have uterus and cervix or dysplastic uterus and cervix. The difficulty in transplanting sigmoid colon with vascular pedicles in some patients, inaccurate evaluation of the length measurement o...
