Dr. Coyle, a colon and rectal specialist, and Dr. Merck, a general surgeon, decided that joining their efforts would be beneficial to both. As partners, they could provide coverage for one another and utilize their skills as surgeons by assisting each other when necessary.

Although Dr. Merck is now deceased, it was their vision to have a facility where cost-effective colonoscopy and ano-rectal surgery could be performed as an office-based procedure in a safe environment.Now over 3000 procedures are performed yearly and most insurance carriers realize the cost effectiveness and safety that accredited office-based surgical facilities can offer.
Services
The diagnosis and treatment of both surgical and non-surgical diseases in the colon, rectum and anus, including benign and malignant diseases. Although many procedures are performed in-office, each patient is considered individually to determine whether treatment should be performed in-office or in the hospital.
Alabama Colon & Rectal Institute (ACRI) is a free standing, private practice in downtown Birmingham, Alabama with four board-certified Colon and Rectal Surgeons. Our practice is limited to diseases of the colon, rectum and anus. We perform surgery at multiple sites including five local hospitals and outpatient operations at our AAAASF nationally accredited office-based surgical facility.
While it may not be the most comfortable subject to discuss, the health of your colon and rectum is important to your overall health. At Alabama Colon & Rectal Institute - affectionately coined "The Butt Hut" - we understand that it may be embarrassing to discuss, or even admit, when you're experiencing issues with your colon or rectum.
Alabama Colon & Rectal Institute, P.C., specializes in colonoscopies, including the diagnosis and treatment of both surgical and non-surgical diseases in the colon. Regardless of age, it's important to know how to reduce the risk of colorectal cancer. Our board-certified colorectal surgeons are passionate about the importance of getting screened and providing peace of mind to their patients.
Transrectal ultrasound, Transrectal ultrasonography, or TRUS for short, is a procedure that helps create an image of the rectum, its wall, and the surrounding tissues. Much like with pregnant women, the images in ultrasound are produced through soundwaves which can travel through body tissue to create an accurate image of human tissue in question.

Tried several times with this clinic couldn’t even get people at the front desk to pick up took a “month and a half” for a “scheduler” to not call me and for me to reach the front desk. The staff is horrible and pass the buck a heck of a lot amongst themselves and the front desk will not make an effort to fix it nor will the practice manager correct or acknowledge the issues. So if you need a serious practice I’d look else were you won’t even get on the schedule and personally I wouldn’t want anyone poking my insides that worked at a place that doesn’t even function on basic communication

From start to finish, Dr. Rosser and his entire staff treated me like family. I had an easy recovery and when I did have questions they were quick to help and ease any fears I had. Would definitely recommend to friends and family in the future.

Had a fantastic experience with Dr. Rosser at the Alabama Colon & Rectal Institute!! Second visit in 10 years!! Dr. Rosser and all of his staff are very attentive to their patients. The prep protocol the institute uses is easy to follow and also does not require as much fluid intake as other facilities do. My husband has used Dr. Beckham at the Institute several times with the same wonderful outcome. I have referred Dr. Rosser myself to several friends - all of them went to Dr. Rosser, and they will never go to another doctor other than Dr. Rosser for their future colonoscopies. ALL had a GREAT

Over the years I've had to utilize their services and always found staff/employees nothing but professional, helpful and genuinely concerned for my health and overall welfare.

The staff at Alabama Colon and Rectal Institute is extremely professional and organized . The receptionists, nurses, nurse anesthetists, and physicians truly make you feel comfortable and at ease ; they don’t mind questions either (which is rare these days ) . A special shout out to Shea (nurse anesthetist) and Dr. Rosser .
I hate I can’t remember the name of the nurse that started the IV and the male nurse anesthetist who explained the anesthesia…..they all did a wonderful job !

This is absolutely the best place to go!!! I was here years ago for a procedure and my mom is here now for a regular colonoscopy. Dr. Rosser is the absolute best and the staff here is 2nd to none. This group makes you comfortable in an uncomfortable situation . I highly recommend this group for all colon and rectal needs.
