Laparoscopy

Written by dr- zhila abedi asl. Posted in Uncategorised

Laparoscopy λαπάρα (lapara), meaning "flank, side", and σκοπέω (skopeo), meaning "to see") is an operation performed in the abdomen or pelvis through small incisions (usually 0.5–1.5 cm) with the aid of a camera. It can either be used to inspect and diagnose a condition or to perform surgery

Types

There are two types of laparoscope: (1) a telescopic rod lens system, that is usually connected to a video camera (single chip or three chip), or (2) a digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system. The mechanism mentioned in the second type is mainly used to improve the image quality of flexible endoscopes replacing traditional fiberscopes. Nevertheless, laparoscopes are rigid endoscopes. The rigidness is required in clinical practice. The rod lens based laparoscopes are highly dominant in practice, due to their fine optical resolution (50um typically, dependant on the aperture size used in the objective lens), and the image quality can be better than the digital cameras if necessary. The second type is very rare in the laparoscope market and hospitals

Surgery

Main article: Laparoscopic surgery

The laparoscope allows doctors to perform both minor and complex surgeries with a few small cuts in the abdomen

There are a number of advantages to the patient with laparoscopic surgery versus an open procedure. These include reduced pain due to smaller incisions and hemorrhaging, and shorter recovery time

Gynecological diagnosis

In gynecology, diagnostic laparoscopy may be used to inspect the outside of the uterus, ovaries and fallopian tubes, for ex
