Due to the presence of two ports in the same wound
the range of their movement is likely to be affected.
Hence, careful attention should be paid to proper align-

where as that of 10 mm port should be as far away from
the skin as possible (Figs 1 to 3). The maneuverability and
the freedom of a port depend on the rotational capacity
or the swing of the ports. With the measures mentioned
above, we have observed that there is adequate overall
