Laparoscopic use of sigmoid colon instead of vagina to complete the province’s first case of vaginal reconstruction, no vaginal stenosis, intestinal stenosis, intestinal adhesions, intestinal fistula, etc., physiological function recovery is good. At the beginning of October this year, 20-year-old girl Xiao He, due to the lack of menstruation, came to the gynecology outpatient clinic of HUHH, and was diagnosed with congenital absence of vagina (commonly known as “stone girl”). Dr. Yang Shaoqin, chief physician of the Department of Obstetrics and Gynecology, and Dr. Qin Changjiang, deputy chief physician of the Department of General Surgery, performed a laparoscopic sigmoid colon vaginoplasty for the patient. During the operation, an incision was made in the patient’s umbilicus, a laparoscope was inserted, a gasless laparoscopic hanger was placed, and then three small incisions of 0.5 cm to 1 cm in diameter were made in the abdomen, and trocars were inserted. About 15 cm of sigmoid colon was intercepted by ultrasonic knife under laparoscopy, and then the severed ends were anastomosed. After a series of operations, the colonic mucosa and perineal skin are finally sutured to form an artificial vagina. The main medical treatment for congenital absence of vagina is artificial vaginoplasty. Over the years, many techniques have been applied to artificial vaginoplasty, including amniotic membrane transplantation, skin flap transplantation, and localized top pressure method, etc. However, these techniques are not satisfactory, while sigmoid colon substitute vaginal reconstruction has many advantages.
