Today's surgery didn't improve Sharon's health. It is important to note that the central problem of Prime Minister Ariel Sharon is the lack of consciousness, not the problem of his intestine area.
During the surgery the cranial pressure was released and some of the blood clots that remained from the previous surgery were drained. At the end of the operation there is no active bleeding.
The surgery proceeded with no complications . . . but . . . today's surgery didn't improve Sharon's health. Every such incident does not improve the prime minister's chances of waking up.
