What kind of “lining” is better? In terms of vaginal anatomy, a properly developed vagina is an “H” shaped “canal” with the cervix at the top and the hymen on the outside. The walls of this “canal” are made up of mucous membrane, muscle layer and fibrous tissue membrane. The sigmoid colon and small intestine have a similar structure and are also close to the pelvic floor, making them ideal for interception as a “lining”. The vascularized graft is more likely to survive, and because the intestinal tube has a secretory function, it avoids the problem of vaginal dryness, with the disadvantage that the odor of the secretions is similar to that of the intestine. From an invasive point of view, our intestinal vaginal substitution procedure creates a new vagina while destroying the integrity of the intestinal canal, which increases the risk of the procedure, even though it does not affect intestinal function. Although it is now possible to perform this procedure laparoscopically, the surgical trauma is still much greater compared to the previous surgical procedures. The surgery is almost perfect, but the surgical trauma is also greatly increased, and the surgical risks have increased in parallel. Risk is always accompanied by hope, and repair is always accompanied by destruction.
