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.
The protrusion of an organ or part of an organ into a natural or artificial orifice.
Downward displacement of the UTERUS. It is classified in various degrees: in the first degree the UTERINE CERVIX is within the vaginal orifice; in the second degree the cervix is outside the orifice; in the third degree the entire uterus is outside the orifice.
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
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.
Radiographic examination of the process of defecation after the instillation of a CONTRAST MEDIA into the rectum.
Herniation of the RECTUM into the VAGINA.
Failure of voluntary control of the anal sphincters, with involuntary passage of feces and flatus.
Pathological developments in the RECTUM region of the large intestine (INTESTINE, LARGE).
The distal segment of the LARGE INTESTINE, between the SIGMOID COLON and the ANAL CANAL.
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.
The application of a caustic substance, a hot instrument, an electric current, or other agent to control bleeding while removing or destroying tissue.
The terminal segment of the LARGE INTESTINE, beginning from the ampulla of the RECTUM and ending at the anus.
Techniques for securing together the edges of a wound, with loops of thread or similar materials (SUTURES).
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.
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.
A segment of the COLON between the RECTUM and the descending colon.
Surgery performed on the digestive system or its parts.
A lesion on the surface of the skin or a mucous surface, produced by the sloughing of inflammatory necrotic tissue.
The normal process of elimination of fecal material from the RECTUM.
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.
