The
operation is performed under general anasthesia; the risks of the
operation are quite small (however not "zero"):
Through a 0.5 cm incision at the navel an optical device
(laparoscope) is brought into the abdominal cavity; through another cut
like that at the lower abdomen the fallopian tubes are grabbed
and electrically scabbed using some plier-like tool. Thus the
tubes are blocked.
