Rectal Prolapse
Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
Uterine Prolapse
Pelvic Organ Prolapse
Abnormal descent of a pelvic organ resulting in the protrusion of the organ beyond its normal anatomical confines. Symptoms often include vaginal discomfort, DYSPAREUNIA; URINARY STRESS INCONTINENCE; and FECAL INCONTINENCE.
Pelvic Floor
Soft tissue formed mainly by the pelvic diaphragm, which is composed of the two levator ani and two coccygeus muscles. The pelvic diaphragm lies just below the pelvic aperture (outlet) and separates the pelvic cavity from the PERINEUM. It extends between the PUBIC BONE anteriorly and the COCCYX posteriorly.
Mitral Valve Prolapse
Defecography
Radiographic examination of the process of defecation after the instillation of a CONTRAST MEDIA into the rectum.
Rectocele
Herniation of the RECTUM into the VAGINA.
Fecal Incontinence
Rectal Diseases
Pathological developments in the RECTUM region of the large intestine (INTESTINE, LARGE).
Rectum
The distal segment of the LARGE INTESTINE, between the SIGMOID COLON and the ANAL CANAL.
Perineum
The body region lying between the genital area and the ANUS on the surface of the trunk, and to the shallow compartment lying deep to this area that is inferior to the PELVIC DIAPHRAGM. The surface area is between the VULVA and the anus in the female, and between the SCROTUM and the anus in the male.
Aortic Valve Prolapse
Anal Canal
The terminal segment of the LARGE INTESTINE, beginning from the ampulla of the RECTUM and ending at the anus.
Cautery
Cystocele
Suture Techniques
Visceral Prolapse
The prolapse or downward displacement of the VISCERA.
Hernia
Protrusion of tissue, structure, or part of an organ through the bone, muscular tissue, or the membrane by which it is normally contained. Hernia may involve tissues such as the ABDOMINAL WALL or the respiratory DIAPHRAGM. Hernias may be internal, external, congenital, or acquired.
Colon, Sigmoid
A segment of the COLON between the RECTUM and the descending colon.
Ulcer
Defecation
The normal process of elimination of fecal material from the RECTUM.
Tricuspid Valve Prolapse
Abnormal protrusion of one or more of the leaflets of TRICUSPID VALVE into the RIGHT ATRIUM during SYSTOLE. This allows the backflow of blood into right atrium leading to TRICUSPID VALVE INSUFFICIENCY; SYSTOLIC MURMURS. Its most common cause is not primary valve abnormality but rather the dilation of the RIGHT VENTRICLE and the tricuspid annulus.
