WHAT’S NEW IN LAPAROSCOPY AND MINIMAL ACCESS SURGERY

Dr Arun Prasad MS,FRCS, Senior Consultant Surgeon, Apollo Hospital, New Delhi

The list of procedures that can be done laparoscopically, thoracoscopically (VATS) or endoscopically is ever expanding. The following is a list of advanced procedures that are being done now using minimal access techniques leading to shorter hospitalization, faster recovery with minimization of pain and discomfort.

As the demands of the surgeons to the industry increases, the latter is trying to respond by giving tools that are more and more minimally invasive.

The most significant new contribution has been the advent of 3 mm instruments. This method is at present available only in a few select centers of the world. As training and experience grows, it will eventually become a standard method and within the next ten years or so, be available at all surgical centers.

HOW IS THIS DIFFERENT FROM CONVENTIONAL LAPAROSCOPY ?

‘Traditional’ laparoscopy required cuts of 11 mm diameter to be able to insert certain instruments like the clip applicator which is used to occlude blood vessels and ducts. Once the more advanced laparoscopic surgeons started stitching these structures by a procedure known as intracorporeal suturing, the need for the 11 mm hole diminished to 5 mm and subsequently instruments that had similar strength with just 3mm diameter arrived.

WHAT ARE THE ADVANTAGES ?

1. The picture on the left shows in pairs, 11mm on the left, 5 mm in the centre and 3 mm instruments on the right. Theoretically it gives the patient 1/3^rd size of cut and hence reduction in the pain and trauma. Also as there is no stitch removal later, the patient is saved the discomfort of stitch removal. Out of station patients need not come back to the surgeon and can be checked by their local doctor.
2. It is cosmetically more acceptable as now even that one stitch of laparoscopic surgery is obsolete. The small cuts are now closed by either medical super glue or sterile paper tapes.
3. Using stitches inside the body makes the internal operation identical to the traditional open surgery with all the added advantages of the minimally invasive instruments. In the traditional laparoscopic method metal clips used for sealing the cut ends are left inside forever but here, absorbable vicryl stitch is used which is identical to the one used in open surgery.
4. Wound infection, swelling etc. incidence is greatly reduced.
5. Rarely hernia have been known to form from 11 mm cuts but are unheard of with 5mm and 3mm cuts.

CAN ALL OPERATIONS BE DONE BY 3MM INSTRUMENTS ?

The answer is no. At times thick walled gall bladders cannot be properly grasped by these fine instruments necessitating the change over to 5 mm instruments. Rarely as is true with traditional laparoscopic surgery, unforeseen circumstances (1-2% cases), may require conversion to open surgery. No surgeon can ever give an undertaking contrary to this.

HOW EXPENSIVE IS ALL THIS CHANGE ? WHO BEARS THE EXTRA COST ?

Change to micro laparoscopy usually means an extra investment of about 3 lakhs (Rs) for the surgeon/ institution. Also, as these instruments are more delicate, their life is short leading to constant recurrent expense.

At our center however, NO extra charge is added to the bill of the patient. The same package applies to all patients.

This is the method of the new millennium.

Dr Arun Prasad is one of the few surgeons worldwide who have taken a lead to provide this service to the patients. Sooner or later all laparoscopic surgeons will adopt this technique.
