Laparoscopic Surgery Procedures By Dr. M.G. Bhat and Dr.JayaBhat

Laparoscopic cholecystectomy is the most common laparoscopic procedure performed

. In this procedure, 5-10mm diameter instruments (graspers, scissors, clip applier) can be introduced by the surgeon into the abdomen through trocars (hollow tubes with a seal to keep the CO2 from leaking). Rather than a minimum 20cm incision as in traditional cholecystectomy, four incisions of 0.5-1.0cm will be sufficient to perform a laparoscopic removal of a gallbladder. Since the gall bladder is similar to a small balloon that stores and releases bile, it can usually be removed from the abdomen by suctioning out the bile and then removing the deflated gallbladder through the 1cm incision at the patient's navel. The length of postoperative stay in the hospital is usually 2-3 days.

In certain advanced laparoscopic procedures where the size of the specimen being removed would be too large to pull out through a trocar site, as would be done with a gallbladder, an incision larger than 10mm must be made. The most common of these procedures are removal of all or part of the colon (colectomy), or removal of the kidney (nephrectomy). Some surgeons perform these procedures completely laparoscopically, making the larger incision toward the end of the procedure for specimen removal, or, in the case of a colectomy, to also prepare the remaining healthy bowel to be reconnected (create an anastomosis). Many other surgeons feel that since they will have to make a larger incision for specimen removal anyway, they might as well use this incision to have their hand in the operative field during the procedure to aid as a retractor, dissector, and to be able to feel differing tissue densities (palpate), as they would in open surgery. This technique is called hand-assist laparoscopy. Since they will still be working with scopes and other laparoscopic instruments, CO2 will have to be maintained in the patient's abdomen, so a device known as a hand access port (a sleeve with a seal that allows passage of the hand) must be used. Surgeons that choose this hand-assist technique feel it reduces operative time significantly vs. the straight laparoscopic approach, as well as providing them more options in dealing with unexpected adverse events (i.e. uncontrolled bleeding) that may otherwise require creating a much larger incision and converting to a fully open surgical procedure.
