Waikato Surgery

Definitions

Endoscopy involves examining the inside of the body with an endoscope, a lighted, flexible instrument that has a small camera on the tip. There are many types of endoscopes, and endoscopy, namedaccording to the organs or areas they are used to examine (e.g. arthroscopy examines joints; bronchoscopy examines the lungs; cystoscopy examines the bladder and urethra; laparoscopy may examine the ovaries, appendix or other abdominal organs; colonoscopy examines the bowel). An endoscope is passed through a natural body opening (e.g. mouth) or a small incision. Small instruments can be inserted through an endoscope and used to take samples of tissues for analysis (biopsy), to remove material (e.g. removing polyps during a colonoscopy), or to carry out a surgical procedure.moreGeneral surgery takes its name from general medicine, and is a surgical specialty focusing on the torso and abdominal organs. This may include the intestines comprising the oesophagus, stomach, small and large intestines, pancreas, liver, gallbladder and bile ducts. It also often deals with diseases and disorders involving the skin and breasts.moreLaparoscopic surgery, also known as ‘keyhole surgery’, is carried out with the aid of a camera inserted into the abdomen or pelvis. A small incision is made in the abdominal wall through which alaparoscope, a flexible lighted tube with a camera attached, is inserted so that structures within the abdomen and pelvis can be examined. The abdominal cavity is made more visible by distending it with an absorbable gas, usually carbon dioxide. A number of major and minor surgeries may be carried out. A variety of tubes and long, narrow instruments can be inserted through the same incision in the skin, or via other small incisions, facilitating a number of procedures without the need for a large surgical incision. The surgeon uses these instruments to manipulate, cut and sew tissue. A number of procedures can be performed laparoscopically, including gallbladder removal (laparoscopic cholecystectomy), oesophageal surgery (laparoscopic fundoplication), colon surgery (laparoscopic colectomy), and surgery on the stomach and spleen. Most patients receive general anaesthetic during the procedure.more
