Surgical union or shunt between ducts, tubes or vessels. It may be end-to-end, end-to-side, side-to-end, or side-to-side.
Inflammation of the COLONIC DIVERTICULA, generally with abscess formation and subsequent perforation.
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.
Death and putrefaction of tissue usually due to a loss of blood supply.
Opening or penetration through the wall of the INTESTINES.
The segment of LARGE INTESTINE between the CECUM and the RECTUM. It includes the ASCENDING COLON; the TRANSVERSE COLON; the DESCENDING COLON; and the SIGMOID COLON.
The terminal segment of the LARGE INTESTINE, beginning from the ampulla of the RECTUM and ending at the anus.
A congenital abnormality characterized by the persistence of the anal membrane, resulting in a thin membrane covering the normal ANAL CANAL. Imperforation is not always complete and is treated by surgery in infancy. This defect is often associated with NEURAL TUBE DEFECTS; MENTAL RETARDATION; and DOWN SYNDROME.
Wounds caused by objects penetrating the skin.
Surgery performed on the digestive system or its parts.
Tumors or cancer of 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.
Tumors or cancer of the RECTUM.
Fastening devices composed of steel-tantalum alloys used to close operative wounds, especially of the skin, which minimizes infection by not introducing a foreign body that would connect external and internal regions of the body. (From Segen, Current Med Talk, 1995)
A solution or compound that is introduced into the RECTUM with the purpose of cleansing the COLON or for diagnostic procedures.
Methods to repair breaks in abdominal tissues caused by trauma or to close surgical incisions during abdominal surgery.
The washing of a body cavity or surface by flowing water or solution for therapy or diagnosis.
Congenital MEGACOLON resulting from the absence of ganglion cells (aganglionosis) in a distal segment of the LARGE INTESTINE. The aganglionic segment is permanently contracted thus causing dilatation proximal to it. In most cases, the aganglionic segment is within the RECTUM and SIGMOID COLON.
Tumors or cancer of the SIGMOID COLON.
Excision of a portion of the colon or of the whole colon. (Dorland, 28th ed)
Surgical construction of an opening into the CECUM with a tube through the ABDOMINAL WALL (tube cecostomy) or by skin level approach, in which the cecum is sewn to the surrounding PERITONEUM. Its primary purpose is decompression of colonic obstruction.
A pouch or sac opening from the COLON.
Endoscopic examination, therapy or surgery of the rectum.
Surgical construction of an artificial opening (stoma) for external fistulization of a duct or vessel by insertion of a tube with or without a supportive stent.
Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.
An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.
The protrusion of an organ or part of an organ into a natural or artificial orifice.
Messages between computer users via COMPUTER COMMUNICATION NETWORKS. This feature duplicates most of the features of paper mail, such as forwarding, multiple copies, and attachments of images and other file types, but with a speed advantage. The term also refers to an individual message sent in this way.
Mechanical food dispensing machines.
The guidelines and policy statements set forth by the editor(s) or editorial board of a publication.

A publication issued at stated, more or less regular, intervals.

A loose confederation of computer communication networks around the world. The networks that make up the Internet are connected through several backbone networks. The Internet grew out of the US Government ARPAnet project and was designed to facilitate information exchange.
A subspecialty of internal medicine concerned with the study of the physiology and diseases of the digestive system and related structures (esophagus, liver, gallbladder, and pancreas).
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.
An abdominal hernia with an external bulge in the GROIN region. It can be classified by the location of herniation. Indirect inguinal hernias occur through the internal inguinal ring. Direct inguinal hernias occur through defects in the ABDOMINAL WALL (transversalis fascia) in Hesselbach's triangle. The former type is commonly seen in children and young adults; the latter in adults.
Protrusion of abdominal structures into the THORAX as a result of congenital or traumatic defects in the respiratory DIAPHRAGM.
A hernia caused by weakness of the anterior ABDOMINAL WALL due to midline defects, previous incisions, or increased intra-abdominal pressure. Ventral hernias include UMBILICAL HERNIA, incisional, epigastric, and spigelian hernias.
A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.
