Sigmoidocele (also known as pouch of Douglas descent) is a medical condition in which a herniation of peritoneum containing loops of redundant sigmoid colon descends (prolapses) into the rectouterine pouch (in females), between the rectum and the vagina. [1] [2] This can obstruct the rectum and cause obstructed defecation syndrome. [3]
Stercoral ulcer is an ulcer of the colon due to pressure and irritation resulting from severe, prolonged constipation due to a large bowel obstruction, damage to the autonomic nervous system, or stercoral colitis. It is most commonly located in the sigmoid colon and rectum.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
In patients with sigmoid volvulus, although abdominal pain may be present, symptoms of constipation may be more prominent. Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. [ 11 ]
The sigmoid colon is completely surrounded by peritoneum (and thus is not retroperitoneal), which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.

The most common signs and symptoms are bleeding, which can vary from minor to severe, rectal prolapse and incomplete evacuation (35%-76% of cases). [4] According to one report, constipation is present in about 55% of cases, but diarrhea is present in 20%–40% of cases. [ 1 ]
Chronic conditions, such as irritable bowel syndrome or Crohn's disease, can cause severe diarrhea lasting for weeks or months. Diseases, drugs, and indigestible dietary fats that interfere with the intestineal absorption may cause steatorrhea (oily rectal discharge & fatty diarrhea) and degrees of FI.
