Colorectal Surgery

Make an Appointment


Colorectal surgeons at Baystate Health specialize in minimally invasive techniques to treat colon, rectal, and anal conditions—including fecal incontinence, diverticulitis, Crohn’s disease, hernia, constipation, and colon cancer.

With extensive experience and the latest minimally invasive techniques, Baystate’s surgeons prioritize your health, comfort, and quality of life.


If you need colorectal surgery because of cancer or a benign (non-cancerous) condition, you deserve a specialist in colon and rectal surgery, not just a general surgeon. You deserve the very best care. And you’ll find that close to home, at Baystate Health.

Our collaborative approach to care means that your surgeon is part of a comprehensive team of registered nurses, nurse practitioners, dietitians, and genetic counselors, as well as doctors from other specialties—such as gastroenterology, radiation therapy, oncology, urology, and urogynecology. Everyone works together to find the right treatment for you.

We bring together advanced treatments with:

  • Multiple locations across western Massachusetts
  • Coordinated, comprehensive care: All specialists, tests, and procedures are available at every location
  • Outstanding outcomes: Our team approach means successful outcomes for our patients

Leadership and Expertise

Baystate Health colorectal surgeons are members of the American Society of Colon and Rectal Surgeons (ASCRS) and are board certified in colorectal surgery. And surgeons at Baystate don’t just perform surgery—they also teach it.

Baystate Medical Center is an academic medical center and training site for the University of Massachusetts Medical School-Baystate— the regional campus of the state's only private medical school. UMMS-Baystate includes ten academic departments, including surgery. Our surgeons are training the surgeons of tomorrow, so you can expect the highest standard of care.

Treatments and Procedures

Innovations in colorectal surgery, combined with our surgeons’ experience, mean fewer complications and a greater quality of life after your surgery.

Advances include minimally invasive surgical techniques (laparoscopic and robotic), ostomy bag alternatives, and procedures that help you keep normal bowel functions. For example, our surgeons use sphincter-sparing treatments whenever possible to give colorectal cancer patients the ability to pass bowel movements naturally, without an ostomy bag, after surgery.

Procedures we offer include:

  • Colectomy
  • Colostomy
  • Endoscopic surgery
  • Hemorrhoidectomy
  • Ileal pouch anal anastomosis (J-pouch)
  • Inflammatory dowel disease (IBD) surgery
  • Internal sphincterotomy
  • InterStim therapy
  • Rectopexy
  • Resection
  • Sacral nerve stimulation
