Thousands of people go through daily life with symptoms of hemorrhoids without receiving treatment. You don’t have to suffer from this pain any longer. Dr. Schub’s Columbia, MD office specializes in treating these often uncomfortable conditions. Two such treatments that Dr. Schub performs in office are hemorrhoid banding and infrared coagulation

Hemorrhoid banding, often called rubber band ligation, is a popular gastroenterology procedure to treat hemorrhoids. Dr. Schub uses the CRH O’Regan System to perform hemorrhoid banding. This procedure takes less than 5 minutes and is painless. a procedure is a nonsurgical procedure to treat internal hemorrhoids that are causing symptoms, such as bleeding. During the procedure the hemorrhoid is tied off at its base with a rubber band, cutting off the blood flow to hemorrhoid. Rubber band ligation is considered to be the most effective nonsurgical treatment for internal hemorrhoids over the long term. Patients are able to resume their normal daily activities immediately afterward as no sedation is required.

Infrared Coagulation is a medical procedure used to treat small and medium-sized hemorrhoids. In situations where hemorrhoid banding isn’t necessary, gastroenterologists like Dr. Schub utilize this technique to alleviate any hemorrhoidal symptoms. During the procedure, the doctor uses a device that creates an intense beam of infrared light. The heat created by the infrared light causes scar tissue, which cuts off the blood supply to hemorrhoid. Hemorrhoid dies and a scar forms on the wall of the anal canal. The scar tissue holds nearby veins in place so they no longer bulge into the anal canal. Patients are able to resume their normal daily activities immediately afterward as no sedation is required.

“Highly Recommended”

"I've been visiting Dr. Schub for years. I have never been dissatisfied whether it's an office visit or colonoscopy. The office is great! Dr. Schub is very personable and explains everything very well. The colonoscopy procedure is great! The staff treats you very well while preparing. No pain, and great after care. I highly recommend this practice!!"

Melissa O

"It has been 10 years"

"Just saw Dr. Schub's page as a suggestion on here. It has been at least 10 years since I saw him and he did the best thing a doctor could do. He did the EGD down my throat. I was out, so I had no issues remembering a camera going down my mouth. We found the issue and fixed it. I've not had to see him again. That is how it should be. I shouldn't need years of follow up, but I know I'd go right back to him if I ever had an issue again."

Scott R

“High Quality Care”

"A high pressure career resulted in several significant medical problems prior to my retirement. Thanks to Dr. Schub and his outstanding staff, these problems were diagnosed early, resolved and monitored regularly, leading to my thoroughly enjoying retirement over the last 8 years. While EGD's and colonoscopy may not be the most enjoyable experiences, I'm extremely grateful for the extremely high quality care I've received."
