Reported narrative: IT WAS REPORTED THAT DURING A SINGLE PORT (SP) DA VINCI-ASSISTED NIPPLE-SPARING MASTECTOMY (NSM) SURGICAL PROCEDURE, THERE WAS A CONVERSION BACK TO OPEN (THE PROCEDURE HAD BEGUN OPEN) TO ADDRESS EXCESSIVE BLEEDING AT THE MEDIAL EDGE OF THE BREAST DUE TO PATIENT ANATOMY AND FOR USER EFFICIENCY. THIS CONVERSION WAS ALREADY ANTICIPATED AS A FEASIBLE AND EXPECTED ALTERNATIVE. THE PROCEDURE WAS DESIGNED TO COMBINE BOTH OPEN AND ROBOTIC TECHNIQUES. THE EXACT AMOUNT OF BLOOD LOST IS UNKNOWN, BUT INTERVENTIONS TO CONTROL THE BLEEDING INCLUDED THE USE OF FLOSEAL, BIPOLAR COAGULATION WITH SP FENESTRATED BIPOLAR, AND LIGASURE DURING THE OPEN PROCEDURE. NO BLOOD TRANSFUSIONS WERE ADMINISTERED.

Reported narrative: A PATIENT IN A STUDY UNDERWENT A DA VINCI-ASSISTED BILATERAL NIPPLE SPARING MASTECTOMY (NSM). AT THE 42-DAY FOLLOW-UP, A NEUROPATHY WAS REPORTED. THE EVENT ONSET DATE HAS BEEN REPORTED AS POST-OPERATIVE DAY #14. THE NEUROPATHY WAS LOCATED BILATERALLY, IN THE RIGHT AND LEFT BREASTS. THE NEUROPATHY PAIN WAS IDENTIFIED BY THE PATIENT AND REPORTED TO THE PLASTICS TEAM THAT SHE WAS UNABLE TO GET AHEAD OF THE PAIN IN HER BREASTS AND ASKED FOR RELIEF. IT WAS DESCRIBED AS "PERSISTENT, SEARING PAIN LOCALIZED TO THE BREAST AREA ABOVE THE NIPPLE AND INCISION LINE, WHICH WORSENS WITH ACTIVITY. THE PAIN IS CONSTANT, NON-RADIATING, AND NOT ASSOCIATED WITH INCISIONAL SITES. THE SKIN IS NUMB, AND ACTIVITIES SUCH AS WALKING OR CAR RIDES EXACERBATE THE PAIN. THE PAIN DOES NOT RADIATE AROUND THE CHEST WALL, ARMS, OR LEGS." THE TISSUE EXPANDERS WERE REPORTED AS UNCOMFORTABLE BUT NOT ATTRIBUTED TO THE CURRENT PAIN. TREATMENT CONSISTED OF REFERRAL TO A PAIN CLINIC AND PRESCRIPTIONS FOR IBUPROFEN, TYLENOL, DICLOFENAC AND GABAPENTIN. A BILATERAL PECS I/II BLOCK IN-CLINIC PROCEDURE WAS SCHEDULED; HOWEVER, THE PATIENT INDICATED THAT THE PRESCRIBED MEDICATIONS HAD RELIEVED THE PAIN AND CANCELED THE NERVE BLO

da Vinci Surgical System — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: A clinical study article reported a retrospective single-center study of consecutive children under 12 months of age who underwent robotic surgery between 2010 and 2020. All procedures were performed using the da Vinci Si surgical system.Postoperative complications were reported in 6 patients, 2 of whom required reoperation. These complications included partial dehiscence of an anorectal anastomosis due to surgical wound infection requiring redo surgery, ileus, accidental gastrostomy outlet requiring endoscopic placement, pleural effusion, bradycardia, and atelectasis.The authors concluded that robotic surgery in newborns and infants can be considered feasible and safe when performed by well-trained surgeons. They also suggested that a wide range of procedures, including complex surgeries in small children, can be carried out safely with a very low complication rate. It was recommended that, further multicenter studies are needed to validate these findings.Intuitive Surgical Inc. (ISI) has made multiple attempts to obtain additional information; however, as of the date of this report, no new information has been obtained.

THE AIM OF THIS STUDY WAS TO ANALYZE RSS ADVANTAGES COMPARED TO FAS AND THE IMPACT OF A DEDICATED NURSING TEAM ON SURGICAL WORKFLOW EFFICIENCY. MATERIALS AND METHODS: WE RETROSPECTIVELY ANALYZED 260 ADULT PATIENTS WITH THORACOLUMBAR DEGENERATIVE/TRAUMATIC INSTABILITY.
