The colorectal surgery team offers expertise in the prevention, diagnosis and treatment of diseases of the anus, colon and rectum. The unparalleled experience and skill of our team and our state-of-the-art equipment enable us to achieve optimal results for our patients.
Contact the Colorectal Surgery Team
The Colorectal Surgery team is located at 208 Collyer Street, Suite 301A in Providence, RI. Hours are Monday through Friday, 9 a.m. to 5 p.m.
Our colorectal surgeons are recognized regionally and nationally as leaders in the field of minimally invasive, endoscopic and laparoscopic procedures as applied to the treatment of inflammatory bowel disease (Crohn’s and ulcerative colitis), colorectal cancer, and diverticulitis.
Our surgeons have mastered the surgical treatment of pelvic floor disorders such as fecal incontinence and rectal prolapse by applying the newest minimally invasive techniques.
We have maintained a strong commitment to the surgical management of common anorectal disorders such as hemorrhoids, fissures and fistula disease at our state-of-the-art outpatient centers. Our surgical outcomes exceed national standards of excellence and safety.
A Team Approach to Colorectal Care
Our multidisciplinary team collaboration with departments such as radiology, gastroenterology, pathology, radiation therapy and oncology allows our physicians and surgeons seamless coordination of patient care.
Patient care is integrated with screening tests, prevention strategies, nutrition management, education and support services for patients and their families, as well as attention to quality-of-life issues. We place particular emphasis on procedures that avoid a permanent colostomy or ileostomy.
Conditions We Treat
We evaluate, diagnose and treat a number of conditions, including:
Colon cancer
Colon precancerous or malignant polyps
Rectal cancer
Rectal precancerous or malignant polyps
We hold the highest level of certification for rectal cancer treatment through the National Accreditation Program for Rectal Cancer (NAPRC). We are one of the only centers in the nation performing Ta-TME—a specialized technique for removing very low rectal cancers while preserving the anus and avoiding the need for a permanent colostomy. In addition, the division offers TEM (transanal endoscopic microsurgery), which enables the removal of rectal tumors without any abdominal incisions.
Diverticulitis
Anal dysplasia and anal cancer
Rectal prolapse/ventral mesh rectopexy
Inflammatory bowel disease (Crohn's and ulcerative colitis)
Benign anorectal conditions such as hemorrhoids, fistulas and fissures
Functional disorders such as fecal incontinence, prolapse and rectocele
Ostomy dysfunctions or complications

Our Technology and Facilities
We are equipped with a special anorectal physiology laboratory. Manometric studies, 3D anal ultrasound, and pudendal nerve studies can be performed to better understand and treat our patients' functional disorders. The lab can also be utilized for testing of pelvic floor problems, as well as for treatment, including biofeedback. Our endoscopy unit is fully equipped for screening, diagnosis and treatment of a variety of colorectal conditions. Our 3D endorectal ultrasound unit is used to properly stage and plan comprehensive treatment of rectal tumors.
Labs are located only at our Collyer Street and Rhode Island Hospital locations. The lab at Rhode Island Hospital is for physiology of fecal incontinence.
In addition, we have an advanced program in robotic surgery. This technique has revolutionized the approach to complex pelvic floor surgery involving patients with rectal cancer. The ability to carry out such precise surgical dissection and reconstruction has led to outstanding results in patient care. This state-of-the-art technique has also been applied to colon cancer surgery as well as diverticulitis and rectal prolapse.
Research and Clinical Trials
Research is currently being conducted to learn more about colorectal cancer and how it affects our patients.
