RAIS is used by surgeons performing laparoscopy. It is a safer and cost-effective alternative to CO2
which is now commonly used in creating surgical space in the abdomen during laparoscopy. However, in
low-resource settings, the availability of CO2 is limited and requires general anesthesia making it harder
to introduce laparoscopy. RAIS can be used under spinal anesthesia and is compatible with a range of
autoclaves, making sterilization easy. RAIS is contraindicated in patients with obesity.

A laparoscopy ( lapar = abdomen, scope = to view ) may be performed to access the abdomen and its
organs for tumors and other lesions, injuries, intra-abdominal bleeding, infections, unexplained
abdominal pain, obstructions, or other conditions. When an abdominal laparoscopy is performed, a
doctor uses an instrument called a laparoscope to look at the abdominal organs. A laparoscope is a long,
thin tube with a high-intensity light and a high-resolution camera at the front. The instrument is inserted
through a small incision in the abdominal wall. The camera sends images to a video monitor allowing
your doctor to see inside your body in real-time, without having to make large incisions. Your doctor can
also obtain biopsy samples during this procedure, as well as perform surgery.

Quicker recovery time: Patients often go home after 24 hours to recover in the comfort of their own
homes.
The small incisions are less painful and patients often need less postoperative pain medication.
Fewer wound infections and scarring.

Gasless Laparoscopic Surgery is a laparoscopic procedure that does not require the use of gas (carbon
dioxide) during the procedure. Surgeons are used to introducing a gas inside the person’s body to be
able to have a better visualization of the part that needs to be operated. However, after realizing that
there are many unfavourable effects of using the conventional laparoscopic method, doctors found a
way to get rid of the gas and still end up with a successful operation.

The insufflation of the abdominal cavity with gas comes with some complications for the patient,
especially those with previous cardiac or respiratory diseases. Though CO2 is useful, it can cause acidosis
(increased acidity) in the body’s vital organs, pulmonary embolism (a bubble of air blocking the blood
vessels in the lungs), poor kidney perfusion, and even a heart attack. In worse cases, accumulation of
carbonic acid can lead to kidney failure or even heart attack. Carbon dioxide can also lower the patient’s
body temperature because of the cold gas.

When surgeons employ a gasless procedure, they have the advantage of using simple surgical
instruments and valveless trocars. This means that the doctor can use the same surgical instruments
used in open surgery with this procedure. One can also do unlimited suction without a loss of exposure.
It also removes the need for general anesthetic, CO2 gas, and expensive instrumentation which are
inaccessible to rural healthcare facilities.

A lot of gasless laparoscopic surgeries have been done and most of them were successful. Many opt for
this procedure because aside from its effectiveness, it is also more affordable than the conventional
laparoscopic method.
