An endoscopy is a simple procedure that allows a doctor to look inside human bodies using an instrument called an endoscope. A cutting tool can be attached to the end of the endoscope, and the apparatus can then be used to perform minor procedures such as tissue biopsies, banding of oesophageal varices or removal of polyps.
Local anesthesia can be used. Analgesics are not always necessary. A paracervical block may be achieved using a lidocaine injection in the upper part of the cervix. Hysteroscopic intervention can also be done under general anesthesia (endotracheal or laryngeal mask) or monitored anesthesia care (MAC). Prophylactic antibiotics are not necessary.
Newer techniques, including single and double-balloon endoscopy have been developed to overcome some of these issues, but are limited by the length of the procedure, and the need for deep sedation or general anesthesia. Spiral enteroscopy is a novel technique that utilizes an overtube with raised spirals affixed on the enteroscope that is ...
A study done in 2003 found that 90% of Pennsylvania medical students had done pelvic exams on anesthetized patients during their gynecology rotation. [5] One medical student described performing them "for 3 weeks, four to five times a day, I was asked to, and did, perform pelvic examinations on anesthetized women, without specific consent, solely for the purpose of my education."
Double-balloon enteroscopy offers a number of advantages to other small bowel image techniques, including barium imaging, wireless capsule endoscopy and push enteroscopy: It allows for visualization of the entire small bowel to the terminal ileum. [1] It allows for the application of therapeutics. [9]
The examination of the colon, to rule out a lesion contributing to blood loss, along with an upper gastrointestinal endoscopy (gastroscopy) to rule out oesophageal, stomach, and proximal duodenal sources of blood loss. Fecal occult blood is a quick test which can be done to test for microscopic traces of blood in the stool. A positive test is ...
Most patients tolerate the procedure with only topical anesthesia of the oropharynx using lidocaine spray. However, some patients may need sedation and the very anxious/agitated patient may even need a general anesthetic. Informed consent is obtained before the procedure. The main risks are bleeding and perforation.
Capsule endoscopy Capsule endoscopes are pill-sized imaging devices that are swallowed by a patient and then record images of the gastrointestinal tract as they pass through naturally. Images are typically retrieved via wireless data transfer to an external receiver.
