X-Ray examination of the colon

X-Ray examination of the colon depict the distribution of gas in the intestines, calcifications, tumor masses, and the size and position of the liver, spleen, and kidneys. In the presence of acute intra-abdominal disease, erect, lateral, and

Aspects of the physiology of the colon

The primary functions of the colon are absorption, secretion, motility, and intraluminal digestion. These interrelated phenomena process ileal effluent and convert it into semisolid feces that are stored until defecation is convenient. Regional variations in function are

Pneumatosis cystoides intestinalis

Pneumatosis cystoides intestinalis is a condition characterized by gas cysts in the wall of the gut and sometimes in the mesentery. When the process is limited to the large intestine, the term pneumatosis coli is used. Cysts

Inflammatory & Ulcerative Diseases of the Small Intestine

Acute Enteritis & Mesenteric Lymphadenitis Acute inflammation of the small intestine (enteritis) often also affects the stomach (gastroenteritis) or the colon (enterocolitis). Involvement of regional lymph nodes is termed mesenteric adenitis. These usually self-limiting illnesses may be

Duration of surgical procedures

The duration of a certain surgical procedure is often mentioned in the literature to document the complexity or simplicity of an operation, or the skill of the surgeons.

Incidental Splenectomy

In a recent large series evaluating reasons for splenectomy from tertiary institutions, the single indication for splenectomy was as an incidental procedure on operations on an adjacent organ. In these situations the spleen needs to be removed

Iatrogenic Splenectomy

Procedures in which mobilization of the left upper quadrant is done (such as reflection of the spleen and pancreas medially to expose retroperitoneal tissue, left adrenalectomy, and left nephrectomy) put the spleen at risk for injury during

Diagnostic Splenectomy

One indication for splenectomy is for diagnosis in an otherwise asymptomatic patient. Splenectomy may be needed to make a diagnosis when an asymptomatic mass lesion is seen within the spleen on CT scan, ultrasound, or MRI scan

Autoimmune hemolytic anemia

The autoimmune hemolytic anemias have been classified according to the temperature at which autoantibodies react with the red cell. This classification is particularly useful, since patients with cold antibodies will not benefit from splenectomy but those with
