    The doctor recapped the exam but I was hoping to see that summary in the after visit summary. For example did she have an estimate on size of tumor. She tried to answer all of our questions but she did not want to over step questions I should get from my oncologist and I understand that.

    This provider seems to have a personality issue. I don't think she really tried to be callous but it came across that way. She seemed most interested in trying to force her point of view and not take mine into consideration. I am also a physician and therefore I would've expected more respect from my opinion then she was willing to share.

    Dr. Chern is an experienced surgeon. There are several areas in which could be better about the experience I've had since being diagnosed with the fistula. First of all it feels like she believes living with a seton is the best option. I've always had to ask about my options. As a clinician myself working in neuro I've made the same mistakes as to assuming people's values and what would be best for someone's quality of life. She was pleasant and answered all my questions and is agreeable to what I decide but I don't feel she is trying to understand my priorities and looking into options. I also find it alarming that surgeons aren't able to speak to the state of the evidence as far as stem cells go. I understand it's difficult to stay up to date and they probably mostly are focused on cancer but fistula is still a major problem that is physically and mentally exhausting. As a clinician I've always prioritized following the research to solve complex problems and I also know that many clinicians do not. I would expect UCSF to be more knowledgeable about treatment options even if they're decades away.

    From the moment Dr. Chern entered the room she showed no empathy towards my medical condition. After a rectal exam she said she could not treat me because I did not need a surgical treatment and she was a surgeon. Her response seemed very inappropriate. There must of been a better way to answer the situation. She indicated I would have to be referred which pleased me because I would not want to be treated by her.

    Dr. Chern was so nice and very easy to talk to. I feel that she is a very good surgeon and knows what she is talking about but she is also very caring and took the time to explain to me the issues with my problem. She was attentive and didn't make me feel like she was in a hurry to be done with me.

    She was phenomenal. Extremely knowledgable and the best provider I've ever seen in regards to the issue I'm trying to resolve. She was absolutely elite

    One frustrating thing about the follow-up appointment is that there was no new information for the doctor to review and no specific next steps etc. Because my condition/infection had already been treated I'm not sure what the value of the follow-up referral was given that there were no new tests or procedures.

    A written instruction of what I needed to do prior to surgery and why would have been helpful. After arriving home I struggled to remember what I needed to do. Also doctor should have asked me if I wanted to do follow up physical therapy locally where I live. Or at home. She assumed I would do this iat UCSF. A phone number would have been helpful to phone the therapy department. I'm not sure who or where I should make the appointment with.

    Very helpful getting me on the schedule and putting me on a cancellation list. She many times with me before I was released

    Dr. Chern is solid and practical. She understand my misunderstandings and know how to assure me. She's very patient with me. She is very knowledgeable. And know how to explain to you why she feels her diagnose is accurate.

    I give my care 150%. I always get questions answered and problems solved
    Jul 30, 2022
    I was told I would get information in the after visit summary. The AVS was several pages long and didn't include anything relevant to my condition or the upcoming surgery. It was basically a FAQ where all the answers to the questions were that it would be answered when the scheduler called me.

    Dr. Chern is a phenomenal doctor and an amazing surgeon. I had the absolute pleasure of being in her care for almost a year and recently had to undergo surgery performed by Dr. Chern as well. She is very professional and has impeccable bedside manners. She definitely knows what she's doing and I couldn't have asked for a better surgeon and for a better experience. I 100% recommend Dr. Chern to anyone who's going to need surgery or even a consultation regarding any IBD issues.

    I was told I would get a letter with recommendations for treatment and never did.

    I don't think there is to much to be done
