About Dr. Baker

James W. Baker, M.D ., F.A.C.S.

Dr. Baker is a Board Certified general and colon-rectal surgeon who has practiced in Knoxville, Tennessee since 1989. He received his Bachelor of Arts degree from Johns Hopkins University and Doctor of Medicine degree from the University of Cincinnati. He completed general surgery residency at Rush-Presbyterian-St. Luke’s Medical Center in Chicago, and his colon and rectal surgery fellowship training at the Ochsner Clinic in New Orleans. His surgical practice has been limited to diseases of the Colon, Rectum, and Anus for the past 23 years.

Dr. Baker has a particular interest in newer procedures, technology, and surgical techniques, especially when they benefit patients with better outcome and more rapid return to function. He performed the first reconstructive pouch procedure (ileo-anal pouch) in East Tennessee for a patient with Familial Adenomatous Polyposis (FAP) in 1989. He was an early proponent of “preoperative” chemotherapy and radiation therapy for rectal cancer patients to help shrink tumors and allow greater chance at curative resection and reconstruction without permanent colostomy. He brought Endo-Rectal Ultrasound to the office environment in 1998 to more accurately assess (stage) rectal cancers and determine tumor depth of penetration and lymph node status prior to surgical treatment. In 2000, American Medical Systems chose Dr. Baker to perform Tennessee’s first artificial bowel sphincter (AMS Neosphincter) implant into a patient with fecal incontinence. Several years ago he began using newer hernia surgery techniques (component separation techniques) with mesh reinforcement to allow more secure and durable repair of giant abdominal wall and peri-stomal hernias. He made available screening techniques (Pap smear/ high resolution endoscopy) utilized by Gynecologic Surgeons for cervical dysplasia and early cervical cancer to the screening and treatment of individuals with high risk anal HPV, anal dysplasia, and anal intraepithelial neoplasia (AIN).  In 2012 he introduced a newer, much less painful, non-excisional surgical treatment for hemorrhoids (Doppler Guided Hemorrhoid Artery Ligation/Mucopexy)
