The translation of anterior rectal protrusion is rectal bulge, which is a protrusion of the anterior rectal wall, also known as anterior rectal distention. It is one of the exit obstruction syndromes. The patient has a weak rectovaginal septum with the rectal wall protruding into the vagina, which is also one of the main factors of defecation difficulties. The disease is mostly seen in middle-aged and elderly women, but in recent years the onset in men has also been reported. Difficulty in defecation is the main symptom of anterior rectal protrusion. When the abdominal pressure increases with force, the fecal mass rushes into the anterior protrusion under pressure, and after stopping force, the fecal mass is squeezed back into the rectum, causing difficulty in defecation. In this way, a vicious circle is formed, and the difficulty in defecation becomes more and more serious. A few patients need to put pressure in the perineum and vagina to assist in defecation, and even put their fingers into the rectum to dig out the fecal masses. Some patients have blood in the stool and pain in the anal canal. Rectal palpation and fecal imaging are the main tests to diagnose rectal prolapse. Rectal palpation can reveal a round or oval weak area in the anterior rectal wall at the upper end of the anal canal that protrudes toward the vagina. The anterior wall of the rectum can be seen to protrude forward on fecal imaging, making it difficult for barium to pass through the anal canal. It is proposed that the anterior rectal protrusion defecography can be divided into three degrees: i.e. mild, with a protrusion depth of 0.6-1.5cm; moderate, 1.6-3cm, and severe ≥3.1cm. Conservative treatment is first used, but laxatives and enemas are not advocated, and the emphasis is on three more, more coarse staple foods or fruits and vegetables rich in dietary fiber; more water; and more activity. Through the above treatment, the symptoms of general patients have improved to different degrees. After 3 months of regular non-surgical efficacy treatment, those whose symptoms do not improve and whose efficacy is not obvious can consider surgical treatment. The main surgical methods are as follows: 1. Endorectal incision repair. 2.Intra-rectal closed suture repair. 3.Intra-vaginal repair. 4, combined rectovaginal repair. However, the main structure of each surgical repair is the rectovaginal septum. Most of the defecation difficulties are significantly improved after surgery.
