Owen Harding Wangensteen
Owen Harding Wangensteen (September 21, 1898 – January 13, 1981) was an American surgeon who developed the Wangensteen tube, which used suction to treat small bowel obstruction, an innovation estimated to have saved a million lives by the time of his death. He founded the Surgical Forum at the American College of Surgeons (ACS) and was renowned for his surgical teaching. Amongst his most notable students were Walton Lillehei, Christiaan Barnard, K. Alvin Merendino, Norman Shumway and Edward Eaton Mason. He made contributions to surgical practices in other areas, including appendicitis, peptic ulcers and particularly gastric cancer. In his later life, he showed a keen interest in the history of medicine and co-wrote a number of books on the subject with his wife. Early life Owen Harding Wangensteen was born in 1898 to Ove Wangensteen and his wife Hannah and brought up on the family farm in Lake Park, Minnesota. His parents were Norwegian-immigrant farmers and he spent his ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Park, Minnesota
Lake Park is a city in Becker County, Minnesota, United States. The population was 728 at the 2020 census. History The area upon where Lake Park was founded, started to be settled in 1841 by fur traders while a Dakota encampment still existed on Lake Flora on which part of the City Park is now located. The area was originally founded as Liberty Township. In 1871, the Liberty Township Board changed the name to Lake Park Township; for which the name "Lake Park" comes from a Dakota phrase of "Where the Prairies meet the Waters" as the site became a railway stop for the Great Northern Railway by the town founder, James Canfield. The city was officially incorporated separate from the township on the along the border of Lake Park and Cuba Townships. It was thenceforth known officially as the Village of Lake Park until the 1970s, when Lake Park was converted by the State of Minnesota into a City of the Fourth Class (Population under 5,000), for which it remains today.

Domestic Pig
The pig (''Sus domesticus''), often called swine, hog, or domestic pig when distinguishing from other members of the genus '' Sus'', is an omnivorous, domesticated, even-toed, hoofed mammal. It is variously considered a subspecies of ''Sus scrofa'' (the wild boar or Eurasian boar) or a distinct species. The pig's head-plus-body length ranges from , and adult pigs typically weigh between , with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed. Compared to other artiodactyls, a pig's head is relatively long and pointed. Most even-toed ungulates are herbivorous, but pigs are omnivores, like their wild relative. Pigs grunt and make snorting sounds. When used as livestock, pigs are farmed primarily for the production of meat, called pork. A group of pigs is called a ''passel'', a ''team'', or a ''sounder''. The animal's bones, hide, and bristles are also used in products. Pigs, especially miniature breeds, are kept as pets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abdominal Distension
Abdominal distension occurs when substances, such as air (gas) or fluid, accumulate in the abdomen causing its expansion. It is typically a symptom of an underlying disease or dysfunction in the body, rather than an illness in its own right. People with this condition often describe it as "feeling bloated". Affected people often experience a sensation of fullness, abdominal pressure, and sometimes nausea, pain, or cramping. In the most extreme cases, upward pressure on the diaphragm and lungs can also cause shortness of breath. Through a variety of causes (see below), bloating is most commonly due to buildup of gas in the stomach, small intestine, or colon. The pressure sensation is often relieved, or at least lessened, by belching or flatulence. Medications that settle gas in the stomach and intestines are also commonly used to treat the discomfort and lessen the abdominal distension. Causes One of the causes of abnormal bloating is excessive eating and air swallowing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasogastric Tube
Nasogastric intubation is a medical process involving the insertion of a plastic tube (nasogastric tube or NG tube) through the nose, down the oesophagus, and down into the stomach. Orogastric intubation is a similar process involving the insertion of a plastic tube (orogastric tube) through the mouth. Abraham Louis Levin invented the NG tube. Nasogastric tube is also known as Ryle's tube in Commonwealth countries, after John Alfred Ryle. Uses A nasogastric tube is used for feeding and administering drugs and other oral agents such as activated charcoal. For drugs and for minimal quantities of liquid, a syringe is used for injection into the tube. For continuous feeding, a gravity based system is employed, with the solution placed higher than the patient's stomach. If accrued supervision is required for the feeding, the tube is often connected to an electronic pump which can control and measure the patient's intake and signal any interruption in the feeding. Nasogastric tubes may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterostomy
An enterostomy ('' entero-'' + '' -stomy''; ) is either (1) a surgical procedure to create a durable opening (called a stoma) through the abdominal wall into an intestine ( small intestine or large intestine) or (2) the stoma thus created. The various types of enterostomy are named according to which intestinal segment is involved. Indications for surgery and complications are dependent on the site of the enterostomy. Gastrostomies and enterostomies can be used to provide nutrition in digestive disorders. Hernia development at both permanent and temporary enterostomy sites in a common complication. See also * Gastrostomy Gastrostomy is the creation of an artificial external opening into the stomach for nutritional support or gastric decompression. Typically this would include an incision in the patient's epigastrium as part of a formal operation. It can be perfor ... References {{reflist Medical procedures ...

Adhesion (medicine)
Adhesions are fibrous bands that form between tissues and organs, often as a result of injury during surgery. They may be thought of as internal scar tissue that connects tissues not normally connected. Pathophysiology Adhesions form as a natural part of the body's healing process after surgery in a similar way that a scar forms. The term "adhesion" is applied when the scar extends from within one tissue across to another, usually across a virtual space such as the peritoneal cavity. Adhesion formation post-surgery typically occurs when two injured surfaces are close to one another. According to the "classical paradigm" of adhesion formation, the pathogenesis starts with inflammation and activation of the coagulation system which causes fibrin deposits onto the damaged tissues. The fibrin then connects the two adjacent structures where damage of the tissues occurred. The fibrin acts like a glue to seal the injury and builds the fledgling adhesion, said at this point to be "fibrinou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Bowel Obstruction
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. Either the small bowel or large bowel may be affected. Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. Mechanical obstruction is the cause of about 5 to 15% of cases of severe abdominal pain of sudden onset requiring admission to hospital. Causes of bowel obstruction include adhesions, hernias, volvulus, endometriosis, inflammatory bowel disease, appendicitis, tumors, diverticulitis, ischemic bowel, tuberculosis and intussusception. Small bowel obstructions are most often due to adhesions and hernias while large bowel obstructions are most often due to tumors and volvulus. The diagnosis may be made on plain X-rays; however, CT scan is more accurate. Ultrasound or MRI may help in the diagnosis of children or pregnant women. The condition may be treated conserva ...

Socratic Method
The Socratic method (also known as method of Elenchus, elenctic method, or Socratic debate) is a form of cooperative argumentative dialogue between individuals, based on asking and answering questions to stimulate critical thinking and to draw out ideas and underlying presuppositions. It is named after the Classical Greek philosopher Socrates and is introduced by him in Plato's Theaetetus as midwifery ( maieutics) because it is employed to bring out definitions implicit in the interlocutors' beliefs, or to help them further their understanding. The Socratic method is a method of hypothesis elimination, in that better hypotheses are found by steadily identifying and eliminating those that lead to contradictions. The Socratic method searches for general commonly held truths that shape beliefs and scrutinizes them to determine their consistency with other beliefs. The basic form is a series of questions formulated as tests of logic and fact intended to help a person or group di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emil Theodor Kocher
Emil Theodor Kocher (25 August 1841 – 27 July 1917) was a Swiss physician and medical researcher who received the 1909 Nobel Prize in Physiology or Medicine for his work in the physiology, pathology and surgery of the thyroid.
