Preoperative Treatment of Rectal-Vaginal Septum Gastrointestinal Stromal Tumors

The most common site of GIST is the digestive tract, but a few (approximately 5%) originate from other soft tissues in the abdominal cavity, such as the greater omentum, mesentery, or retroperitoneum. These tumors are called extra-gastrointestinal stromal tumors (EGIST). Due to the special location, the treatment of EGIST which occur in the pelvic floor region (including the rectum, rectovaginal septum, posterior vaginal wall, anterior and posterior bladder regions, anterior and posterior prostate regions, and presacral region) requires the protection of pelvic floor organs, so clinicians need to pay more attention to it.
