I had a colonoscopy last week, Bangkok Hospital Hat Yai. Total cost, including the removal of five polyps with biopsies, thankfully all benign, was Bht50k. Unlike my previous experience at the Sikarin Hospital Hat Yai I felt no discomfort during the procedure, I was fully sedated and woke up in the recovery room. Prep with Picoprep wasn't so bad as previous prep regimes. All in all I was very happy with the Bangkok Hospital Hat Yai.
