Solitary rectal ulcer syndrome (SRUS or SRU) is a chronic disorder of the rectal mucosa (the lining of the rectum). [1] Very often but not always it occurs in association with varying degrees of rectal prolapse .
Rectal mucosal prolapse (mucosal prolapse, anal mucosal prolapse) is a sub-type of rectal prolapse, and refers to abnormal descent of the rectal mucosa through the anus. [21] It is different to an internal intussusception (occult prolapse) or a complete rectal prolapse (external prolapse, procidentia) because these conditions involve the full ...
Plummer–Vinson syndrome (also known as Paterson–Kelly syndrome [1] or Paterson–Brown-Kelly syndrome in the UK [2]) is a rare disease characterized by dysphagia (difficulty swallowing), iron-deficiency anemia, glossitis (inflammation of the tongue), cheilosis (cracking at the corners of the mouth), and esophageal webs (thin membranes in the esophagus that can cause obstruction).

Ventral rectopexy is a surgical procedure for external rectal prolapse, internal rectal prolapse (rectal intussusception), and sometimes other conditions such as rectocele, obstructed defecation syndrome, or solitary rectal ulcer syndrome.
The solitary lymphatic nodules are found scattered throughout the mucous membrane of the small intestine, but are most numerous in the lower part of the ileum. Their free surfaces are covered with rudimentary villi , except at the summits, and each gland is surrounded by the openings of the intestinal glands.
Juvenile polyps are usually sporadic, occurring in isolation, although they may occur as a part of juvenile polyposis syndrome. Sporadic juvenile polyps may occur in any part of the colon, but are usually found in the distal colon ( rectum and sigmoid ).
Lichen planus may be categorized as affecting mucosal or cutaneous surfaces.. Cutaneous forms are those affecting the skin, scalp, and nails. [10] [11] [12]Mucosal forms are those affecting the lining of the gastrointestinal tract (mouth, pharynx, esophagus, stomach, anus), larynx, and other mucosal surfaces including the genitals, peritoneum, ears, nose, bladder and conjunctiva of the eyes.
[2]: 37 The various types of prolapse of the posterior compartment (e.g. external rectal prolapse, mucosal prolapse and internal rectal intussusception & solitary rectal ulcer syndrome) may also cause coexisting obstructed defecation. [citation needed]
