  • So incredibly pleased with the results of my laparoscopic cholecystectomy done by Mr Wan. Knew I was in safe hands from the first consultation. Didn't treat me any differently because I was a Dr, which I appreciated - I was guided every step of the way by Mr Wan. He took his time to explain and assumed no prior knowledge on my part. Surgery went very well, practically zero scars post surgery and my follow up was meticulously done by Mr Wan. An excellent surgeon.
