BASED ON THE INFORMATION PROVIDED AT THIS TIME, THIS COMPLAINT IS BEING REPORTED DUE TO THE FOLLOWING CONCLUSION: DURING A DA VINCI-ASSISTED SURGICAL PROCEDURE, IT WAS ALLEGED THAT A FRAGMENT BROKE OFF AND FELL INSIDE THE PATIENT. ALL FRAGMENTS WERE RETRIEVED AND NO ADDITIONAL SURGICAL INTERVENTION WAS REQUIRED. HOWEVER, AT THIS TIME, IT IS UNKNOWN WHAT CAUSED THE BREAKAGE TO OCCUR.
