Patient Comments (2)
Dr. Kaneshiro is friendly and professional. He took the time to explain his findings each time he performed colonoscopies for me by repeatedly calling me on the phone.
I have seen my fair share of GI Drs since I wasn't 18, having CROHNS and over 20 surgeries. I fight hard to live as normal a life as possible. Dr. Kaneshiro was clearly inexperienced with my particular issue. He failed to fully read the history I typed up and blew me off with regard to my knowledge of my own body. I would not recommend him if you are female and familiar with your own disease. I felt he truly took an attitude. His understudy was much more personable and knowledgeable.
Hello Denise, I am truly sorry for your dissatisfaction with your visit and appreciate your feedback. Just to clarify, you specifically wanted antibiotics to use indefinitely for chronic small intestinal bacterial overgrowth and I'm sorry that I could not recommend safe options to be on long term. Furthermore, you mentioned a history of Crohn's disease but did not want to discuss this at all during the visit or alternative explanations that could be contributing to your symptoms other than SIBO.
