Diagnostic Laparoscopy

Diagnostic laparoscopy is a keyhole procedure used to look directly inside the abdomen or pelvis when other tests have not given a clear answer.

Why it may be recommended

  • Abdominal or pelvic pain that remains unexplained after scans and blood tests
  • Suspected endometriosis or adhesions, which imaging may not show reliably
  • Taking a biopsy from an organ or from tissue lining the abdomen
  • Assessing the extent of a known condition before planning treatment
  • Investigating injury after abdominal trauma, in selected situations

Doctors normally use less invasive tests first. Diagnostic laparoscopy is considered when a direct look is likely to change the diagnosis or the treatment plan.

What happens during the procedure

It is usually performed under general anaesthesia. One small cut, often near the navel, allows the camera to enter after the abdomen is inflated with gas; one or two further small cuts may be used for instruments. The surgeon inspects the organs systematically and may take photographs or samples. If a treatable problem is found, the surgeon may treat it in the same sitting, if that was agreed with you beforehand.

Ask in advance what will happen if something unexpected is found, so the consent covers it.

Recovery in general terms

  • Many diagnostic procedures are day-care, with discharge the same day.
  • Mild wound pain, bloating and shoulder-tip discomfort typically settle in days.
  • Results from biopsies usually take some time; a follow-up appointment is arranged to discuss findings.

Limitations

A normal laparoscopy does not always mean nothing is wrong; some conditions are not visible or lie outside the area examined. The procedure carries the same general risks as other laparoscopic surgery, which is why it is not used routinely. See our risks page and discuss the balance of benefit and risk with your doctor.
