Abdominal Injuries
General or unspecified injuries involving organs in the abdominal cavity.
Laparoscopy
A procedure in which a laparoscope (LAPAROSCOPES) is inserted through a small incision near the navel to examine the abdominal and pelvic organs in the PERITONEAL CAVITY. If appropriate, biopsy or surgery can be performed during laparoscopy.
Intestinal Obstruction
Abdomen, Acute
A clinical syndrome with acute abdominal pain that is severe, localized, and rapid in onset. Acute abdomen may be caused by a variety of disorders, injuries, or diseases.
Peritoneal Lavage
Abdomen
That portion of the body that lies between the THORAX and the PELVIS.
Hemoperitoneum
Accumulations of blood in the PERITONEAL CAVITY due to internal HEMORRHAGE.
Ileal Diseases
Pathological development in the ILEUM including the ILEOCECAL VALVE.
Wounds, Nonpenetrating
Abdominal Wall
The outer margins of the ABDOMEN, extending from the osteocartilaginous thoracic cage to the PELVIS. Though its major part is muscular, the abdominal wall consists of at least seven layers: the SKIN, subcutaneous fat, deep FASCIA; ABDOMINAL MUSCLES, transversalis fascia, extraperitoneal fat, and the parietal PERITONEUM.
Pneumoperitoneum
A condition with trapped gas or air in the PERITONEAL CAVITY, usually secondary to perforation of the internal organs such as the LUNG and the GASTROINTESTINAL TRACT, or to recent surgery. Pneumoperitoneum may be purposely introduced to aid radiological examination.
Postoperative Complications
Abdominal Wound Closure Techniques
Abdominal Neoplasms
Abdominal neoplasms refer to abnormal growths or tumors occurring within the abdominal cavity, which can be benign or malignant, and affect various organs such as the pancreas, liver, kidneys, or intestines.
Peritoneal Diseases
Pathological processes involving the PERITONEUM.
Peritonitis
INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.
Surgical Wound Dehiscence

A type of ectopic pregnancy in which the EMBRYO, MAMMALIAN implants in the ABDOMINAL CAVITY instead of in the ENDOMETRIUM of the UTERUS.
Colonic Diseases
Compartment Syndromes
Conditions in which increased pressure within a limited space compromises the BLOOD CIRCULATION and function of tissue within that space. Some of the causes of increased pressure are TRAUMA, tight dressings, HEMORRHAGE, and exercise. Sequelae include nerve compression (NERVE COMPRESSION SYNDROMES); PARALYSIS; and ISCHEMIC CONTRACTURE.
Ileus
A condition caused by the lack of intestinal PERISTALSIS or INTESTINAL MOTILITY without any mechanical obstruction. This interference of the flow of INTESTINAL CONTENTS often leads to INTESTINAL OBSTRUCTION. Ileus may be classified into postoperative, inflammatory, metabolic, neurogenic, and drug-induced.
Peritonitis, Tuberculous
A form of PERITONITIS seen in patients with TUBERCULOSIS, characterized by lesion either as a miliary form or as a pelvic mass on the peritoneal surfaces. Most patients have ASCITES, abdominal swelling, ABDOMINAL PAIN, and other systemic symptoms such as FEVER; WEIGHT LOSS; and ANEMIA.
Wounds, Gunshot
Treatment Outcome
Bezoars
Rupture, Spontaneous
Intestinal Fistula
An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
Tomography, X-Ray Computed
Ovarian Cysts
General term for CYSTS and cystic diseases of the OVARY.
Pregnancy, Ectopic
A potentially life-threatening condition in which EMBRYO IMPLANTATION occurs outside the cavity of the UTERUS. Most ectopic pregnancies (>96%) occur in the FALLOPIAN TUBES, known as TUBAL PREGNANCY. They can be in other locations, such as UTERINE CERVIX; OVARY; and abdominal cavity (PREGNANCY, ABDOMINAL).
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.
Intussusception
A form of intestinal obstruction caused by the PROLAPSE of a part of the intestine into the adjoining intestinal lumen. There are four types: colic, involving segments of the LARGE INTESTINE; enteric, involving only the SMALL INTESTINE; ileocecal, in which the ILEOCECAL VALVE prolapses into the CECUM, drawing the ILEUM along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the COLON.
Subphrenic Abscess
Accumulation of purulent EXUDATES beneath the DIAPHRAGM, also known as upper abdominal abscess. It is usually associated with PERITONITIS or postoperative infections.
Omentum
A double-layered fold of peritoneum that attaches the STOMACH to other organs in the ABDOMINAL CAVITY.
Hernia, Ventral
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.
Meckel Diverticulum
Suture Techniques
Techniques for securing together the edges of a wound, with loops of thread or similar materials (SUTURES).
Retrospective Studies
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

A condition in which functional endometrial tissue is present outside the UTERUS. It is often confined to the PELVIS involving the OVARY, the ligaments, cul-de-sac, and the uterovesical peritoneum.
Leiomyoma
Mesentery
A layer of the peritoneum which attaches the abdominal viscera to the ABDOMINAL WALL and conveys their blood vessels and nerves.
Hodgkin Disease
A malignant disease characterized by progressive enlargement of the lymph nodes, spleen, and general lymphoid tissue. In the classical variant, giant usually multinucleate Hodgkin's and REED-STERNBERG CELLS are present; in the nodular lymphocyte predominant variant, lymphocytic and histiocytic cells are seen.

Abdominal Muscles
Muscles forming the ABDOMINAL WALL including RECTUS ABDOMINIS, external and internal oblique muscles, transversus abdominis, and quadratus abdominis. (from Stedman, 25th ed)
Peritoneum
A membrane of squamous EPITHELIAL CELLS, the mesothelial cells, covered by apical MICROVILLI that allow rapid absorption of fluid and particles in the PERITONEAL CAVITY. The peritoneum is divided into parietal and visceral components. The parietal peritoneum covers the inside of the ABDOMINAL WALL. The visceral peritoneum covers the intraperitoneal organs. The double-layered peritoneum forms the MESENTERY that suspends these organs from the abdominal wall.
