Laparoscopic
Laparoscopy () is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.MedlinePlus > Laparoscopy Update Date: 21 August 2009. Updated by: James Lee, MD // No longer valid Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time.

Cholecystectomy
Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique. The surgery is usually successful in relieving symptoms, but up to 10 percent of people may continue to experience similar symptoms after cholecystectomy, a condition called postcholecystectomy syndrome. Complications of cholecystectomy include bile duct injury, wound infection, bleeding, retained gallstones, abscess formation and stenosis (narrowing) of the bile duct. Medical use Pain and complications caused by gallstones are the most common reasons for removal of the gallbladder. The gallbladder can also be removed in order to treat biliary dyskinesia or gallbladder cancer. Gallstones are very common but ...

Nephrectomy
A nephrectomy is the surgical removal of a kidney, performed to treat a number of kidney diseases including kidney cancer. It is also done to remove a normal healthy kidney from a living or deceased donor, which is part of a kidney transplant procedure. History The first recorded nephrectomy was performed in 1861 by Erastus B. Wolcott in Wisconsin. The patient had had a large tumor and the operation was initially successful, but the patient died fifteen days later. The first planned nephrectomy was performed by the German surgeon Gustav Simon on August 2, 1869, in Heidelberg. Simon practiced the operation beforehand in animal experiments. He proved that one healthy kidney can be sufficient for urine excretion in humans. Indications There are various indications for this procedure, including renal cell carcinoma, a non-functioning kidney (which may cause high blood pressure) and a congenitally small kidney (in which the kidney is swelling, causing it to press on nerves, which ca ...

Colectomy
Colectomy ('' col-'' + '' -ectomy'') is bowel resection of the large bowel ( colon). It consists of the surgical removal of any extent of the colon, usually segmental resection (partial colectomy). In extreme cases where the entire large intestine is removed, it is called total colectomy, and proctocolectomy ('' procto-'' + ''colectomy'') denotes that the rectum is included. Indications Some of the most common indications for colectomy are: * Colon cancer * Diverticulitis and diverticular disease of the large intestine * Trauma * Inflammatory bowel disease such as ulcerative colitis or Crohn's disease. Colectomy neither cures nor eliminates Crohn's disease, instead only removing part of the entire diseased large intestine. A colectomy is considered a "cure" for ulcerative colitis because the disease attacks only the large intestine and therefore will not be able to flare up again if the entire large intestine (cecum, ascending colon, transverse colon, descending colon and si ...

Gallbladder
In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives and stores bile, produced by the liver, via the common hepatic duct, and releases it via the common bile duct into the duodenum, where the bile helps in the digestion of fats. The gallbladder can be affected by gallstones, formed by material that cannot be dissolved – usually cholesterol or bilirubin, a product of haemoglobin breakdown. These may cause significant pain, particularly in the upper-right corner of the abdomen, and are often treated with removal of the gallbladder (called a cholecystectomy). Cholecystitis, inflammation of the gallbladder, has a wide range of causes, including result from the impaction of gallstones, inf ...

Trocar
A trocar (or trochar) is a medical or veterinary device that is made up of an awl (which may be a metal or plastic sharpened or non-bladed tip), a cannula (essentially a hollow tube), and a seal. Trocars are placed through the abdomen during laparoscopic surgery. The trocar functions as a portal for the subsequent placement of other instruments, such as graspers, scissors, staplers, etc. Trocars also allow the escape of gas or fluid from organs within the body. Etymology The word ''trocar'', less commonly ''trochar'', comes from French ''trocart'', ''trois-quarts'' (three-fourths), from ''trois'' 'three' and ''carre'' 'side, face of an instrument', first recorded in the ''Dictionnaire des Arts et des Sciences'', 1694, by Thomas Corneille, younger brother of Pierre Corneille. History Originally, doctors used trocars to relieve pressure build-up of fluids (edema) or gases (bloating). Patents for trocars appeared early in the 19th century, although their use dated back possibly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Kelling
Georg Kelling (7 July 1866 – 14 February 1945) was a German internist and surgeon who was a laparoscopy pioneer and in 1901 performed the first laparoscopic surgery on a dog. He studied medicine at the Universities of Leipzig and Berlin. He earned his medical doctorate in 1890, and later worked as a physician at the city hospital in Dresden. In the 1890s, Kelling devised an esophagoscope Kelling specialized in gastrointestinal physiology and anatomy. He is credited with performing the first laparoscopic examination, a procedure he referred to as " celioscopy". In 1901 he performed the procedure on the abdomen of a dog using a Nitze-cystoscope. Prior to cystoscopic viewing of the abdomen, Kelling insufflated it with filtered air via a device known as a trocar. Insufflation was used to create a pneumoperitoneum in order to prevent intra-abdominal bleeding. Kelling and his wife were killed during the Allied bombing of Dresden in 1945.

Minimally Invasive Procedure
Minimally invasive procedures (also known as minimally invasive surgeries) encompass surgical techniques that limit the size of incisions needed, thereby reducing wound healing time, associated pain, and risk of infection. Surgery by definition is invasive and many operations requiring incisions of some size are referred to as ''open surgery''. Incisions made during open surgery can sometimes leave large wounds that may be painful and take a long time to heal. Advancements in medical technologies have enabled the development and regular use of minimally invasive procedures. For example, endovascular aneurysm repair, a minimally invasive surgery, has become the most common method of repairing abdominal aortic aneurysms in the US as of 2003. The procedure involves much smaller incisions than the corresponding open surgery procedure of open aortic surgery. Interventional radiologists were the forerunners of minimally invasive procedures. Using imaging techniques, radiologists wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abdomen
The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior (anatomy), posterior tagma (biology), tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between Lumbar vertebrae, L5 and Vertebra#Sacrum, S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body c ...

Insufflation (medicine)
Insufflation ( la, insufflare, lit=to blow into) is the act of blowing something (such as a gas, powder, or vapor) into a body cavity. Insufflation has many medical uses, most notably as a route of administration for various drugs. Medical uses Surgery Gases are often insufflated into a body cavity to inflate the cavity for more workroom, e.g. during laparoscopic surgery. The most common gas used in this manner is carbon dioxide, because it is non-flammable, colorless, and dissolves readily in blood. Diagnostics Gases can be insufflated into parts of the body to enhance radiological imaging or to gain access to areas for visual inspection (e.g. during colonoscopy). Respiratory assistance Oxygen can be insufflated into the nose by nasal cannulae to assist in respiration. Mechanical insufflation-exsufflation simulates a cough and assists airway mucus clearance. It is used with patients with neuromuscular disease and muscle weakness due to central nervous system injury. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannula
A cannula (; Latin meaning 'little reed'; plural or ) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 24 gauge. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula (extubation), especially of a tracheostomy cannula, once a physician determines it is no longer needed for breathing. Medicine Cannulas normally come with a trocar inside. The trocar is a needle, which punctures the body in order to get into the intended space. Many types of cannulas exist: Intravenous cannulas are the most common in hospital use. A variety of cannulas are used to establish cardiopulmonary bypass in cardiac surgery. A nasal cannula is a piece of plastic tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
