Colorectal Surgery

Conditions affecting the colon and rectum are relatively common, ranging in severity from mild to debilitating and life-threatening. The Division of Colorectal Surgery at Waterbury HEALTH specializes in the care of patients who require surgery for the management and treatment of colorectal conditions.

Our team of board-certified surgeons, nurses, and technicians have the depth of knowledge and expertise to provide the highest quality care. We work closely with patients and their loved ones to develop a comprehensive plan of care for the best possible outcomes. The Division of Colorectal Surgery at Waterbury HEALTH possesses clinical areas of expertise that span a wide range of colorectal conditions, including:

  • Colon cancer
  • Rectal cancer
  • Anal cancer
  • Hemorrhoids
  • Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis
  • Incontinence
  • Rectal prolapse
  • Anal fissures and fistulas

We perform operations using minimally invasive techniques whenever possible, such as laparoscopy and robotic surgery, which are associated with less pain, shorter hospital stays, and fewer complications. We offer both common and state-of-the-art procedures for colorectal conditions, including:

  • Open, laparoscopic, and robotic colon resections
  • Stapled hemorrhoid treatment
  • J-pouch reconstruction
  • Stricture repair
  • Minimally invasive anal procedures

The Division of Colorectal Surgery at Waterbury HEALTH is led by Dr. John Zhang, a board-certified surgeon who specializes in colorectal and general surgery and is trained in both laparoscopic and robotic technologies. He is Greater Waterbury’s only surgeon certified by the American Board of Colon and Rectal Surgery.
