Laparoscopy Health Article

Definition

Laparoscopy is a minimally invasive procedure used as a diagnostic tool and surgical procedure that is performed to examine the abdominal and pelvic organs, or the thorax, head, or neck. Tissue samples can also be collected for biopsy using laparoscopy and malignancies treated when it is combined with other therapies. Laparoscopy can also be used for some cardiac and vascular procedures.

Purpose

Laparoscopy is performed to examine the abdominal and pelvic organs to diagnose certain conditions and—depending on the condition—can be used to perform surgery. Laparoscopy is commonly used in gynecology to examine the outside of the uterus, the fallopian tubes, and the ovaries—particularly in pelvic pain cases
where the underlying cause cannot be determined using diagnostic imaging (ultrasound and computed tomography). Examples of gynecologic conditions diagnosed using laparoscopy include endometriosis, ectopic pregnancy, ovarian cysts, pelvic inflammatory disease [PID], infertility, and cancer. Laparoscopy is used in general surgery to examine the abdominal organs, including the gallbladder, bile ducts, the liver, the appendix, and the intestines.

During the laparoscopic surgical procedure, certain conditions can be treated using instruments and devices specifically designed for laparoscopy. Medical devices that can be used in conjunction with laparoscopy include surgical lasers and electrosurgical units. Laparoscopic surgery is now preferred over open surgery for several types of procedures because of its minimally invasive nature and its association with fewer complications.

Microlaparoscopy can be performed in the physician's office using smaller laparoscopes. Common clinical applications in gynecology include pain mapping (for endometriosis), sterilization, and fertility procedures. Common applications in general surgery include evaluation of chronic and acute abdominal pain (as in appendicitis), basic trauma evaluation, biopsies, and evaluation of abdominal masses.

Laparoscopy is commonly used by gynecologists, urologists, and general surgeons for abdominal and pelvic applications. Laparoscopy is also being used by orthopedic surgeons for spinal applications and by cardiac surgeons for minimally invasive heart surgery. As of 2003, procedures under investigation for possible laparoscopy included thyroidectomy and parathyroidectomy.
