Isolated rectal ulcer syndrome is a rare disorder that involves discomfort during defecation, a feeling of incomplete bowel movements, and sometimes blood and mucus passing through the rectum. Possibly due to local ischemic lesions of the distal rectal mucosa Diagnosis is clinically confirmed by sigmoidoscopy and biopsy.

Treatment consists of dietary modification for mild disease, and surgery is sometimes necessary if the cause is rectal prolapse. Isolated rectal ulcer syndrome is a rare disorder that occurs in people with chronic constipation and is poorly understood.

The colon, also known as the large intestine, is the last part of the digestive system, attached to the last part of the digestive system, the anal canal. The colon consists of the right colon (also known as the ascending colon) starting at the cecum where the small intestine empties into the large intestine. Continues with the transverse colon, then descends into the left colon (also known as the descending colon), and finally the sigmoid colon connects to the rectum. The colon, also known as the large intestine, is the last part of the digestive system, attached to the last part of the digestive system, the anal canal. The colon consists of the right colon (also known as the ascending colon) starting at the cecum where the small intestine empties into the large intestine. Continues with the transverse colon, then descends into the left colon (also known as the descending colon), and finally the sigmoid colon connects to the rectum.
The colon's main function is to receive digested food and absorb water, electrolytes from food and along with the breakdown of food residues by bacteria into feces. Holding stool until there is enough colon will contract to create peristalsis and excrete stool through the anus.
The rectum is the last part of the digestive tract, connecting with the anus, which holds the stool before it is expelled.

The rectum is an organ located in the abdomen, connecting the colon and the anal canal. The rectum is a straight segment of intestine about 11 - 15cm long, the first part of the rectum is shaped like the letter sigma, the last part of the rectum dilates to form a ball of the rectum. When viewed from the side, the rectum is shaped like a question mark, lying around the small intestine, curving along the anterior surface of the coccyx.
According to the skeletal structure and nervous system, the rectum is located in front of the sacrum. The position of the rectum in men and women is different due to the difference in the structure of the genital organs:
In men: the position of the rectum is behind the bladder, vas deferens, seminal vesicles, prostate gland. The rectum connects to the center of the pelvic floor. In women: the rectum is located in the uterus and vagina. Anterior is the cervix, the body of the uterus, and the vaginal vault. Behind the rectum is the part of the peritoneum of the rectum that attaches to the posterior wall of the vagina.

Isolated rectal ulcer syndrome is a condition that occurs when one or more open sores develop in the rectum. The rectum is a muscular tube that connects to the end of the large intestine. Stool passes through the rectum out of the body.
Isolated rectal ulcer syndrome is a rare and little known disorder that often occurs in people with chronic constipation. Isolated rectal ulcer syndrome can cause rectal bleeding and strain on bowel movements. Despite its solitary name, sometimes more than one rectal ulcer occurs in isolated rectal ulcer syndrome.
Solitary rectal ulcer syndrome most commonly involves a single ulcer, but occasionally more than one rectal ulcer may occur or multiple polyp-like lesions may form. Isolated rectal ulcer syndrome is a rare and poorly understood disorder that occurs in people with chronic constipation.

The cause of isolated rectal ulcer syndrome is not always clear. Doctors believe that stress or trauma to the rectum can trigger ulcerative colitis.
Examples of situations that can cause damage to the rectum include:
Constipation or tight stools Poor bowel movements Rectal prolapse, which occurs when the rectum protrudes from the anus Uncoordinated contractions of the muscles in the pelvic floor slow blood flow to the rectum Attempts to remove compacted stool by hand Intussusception, which occurs when one part of the intestine slides inside another
