Colostomy
The surgical construction of an opening between the colon and the surface of the body.
Ileostomy
Surgical creation of an external opening into the ILEUM for fecal diversion or drainage. This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.
Surgical Stomas
Sigmoid Diseases
Pathological processes in the SIGMOID COLON region of the large intestine (INTESTINE, LARGE).
Colonic Diseases
Pathological processes in the COLON region of the large intestine (INTESTINE, LARGE).
Rectovaginal Fistula
An abnormal anatomical passage between the RECTUM and the VAGINA.
Rectum
Fournier Gangrene
An acute necrotic infection of the SCROTUM; PENIS; or PERINEUM. It is characterized by scrotum pain and redness with rapid progression to gangrene and sloughing of tissue. Fournier gangrene is usually secondary to perirectal or periurethral infections associated with local trauma, operative procedures, or urinary tract disease.
Rectal Diseases
Pathological developments in the RECTUM region of the large intestine (INTESTINE, LARGE).
Neodymium
Intestinal Volvulus
A twisting in the intestine (INTESTINES) that can cause INTESTINAL OBSTRUCTION.
Intestinal Obstruction
Any impairment, arrest, or reversal of the normal flow of INTESTINAL CONTENTS toward the ANAL CANAL.

Diverticulitis, Colonic
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.
Colon
Anal Canal
The terminal segment of the LARGE INTESTINE, beginning from the ampulla of the RECTUM and ending at the anus.
Anus, Imperforate
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.
Anus Neoplasms
Tumors or cancer of 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.
Rectal Neoplasms
Tumors or cancer of the RECTUM.
Surgical Staplers
Enema
Abdominal Wound Closure Techniques
Therapeutic Irrigation
Hirschsprung Disease
Sigmoid Neoplasms
Tumors or cancer of the SIGMOID COLON.
Cecostomy
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.
Diverticulum, Colon
A pouch or sac opening from the COLON.
Proctoscopy
Endoscopic examination, therapy or surgery of the rectum.
Ostomy

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.
Hernia, Inguinal
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.
Hernia, Diaphragmatic
Hernia, Ventral
Hernia, Abdominal
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.
