Laparoscopy.

Laparoscopy is commonly used by gynaecologists. This is when a small telescope is put through a cut in your belly button. This allows the doctor to see inside your pelvis. See separate leaflet called Laparoscopy and laparoscopic surgery for further information.

Doctors who specialise in the bowel may use flexible telescopes to look inside your bowel. The gullet and stomach can be seen by gastroscopy. See separate leaflet called Gastroscopy (endoscopy). The lower bowel (rectum and colon) are looked at by colonoscopy.
