For Colon and Rectal Surgery, DHI’s Robotic and Minimally Invasive Options Preserve More Normal Function

Physicians across the Tampa Bay area and throughout the state of Florida refer their patients to the Digestive Health Institute for minimally invasive colon and rectal surgery. This is because Dr. Allen Chudzinski and Dr. Haane Massarotti, our skilled colon and rectal surgeons, provide the latest and least invasive surgical treatments for colorectal cancer, inflammatory bowel disease, and other conditions of the colon and rectum. Our surgeons are supported by the state-of-the-art robotic technology.

Minimally Invasive Colorectal Surgery to Provide Maximum Treatment Results

Dr. Chudzinski and Dr. Massarotti are guided by the principle of using the least invasive surgery that will still give patients the treatment results they need. They look for ways to perform procedures effectively while leaving patients with as much normal bowel function as possible. As often as they can, our colon and rectal surgeons also use laparoscopic tools to offer patients a minimally invasive surgery. While not every patient is a good candidate for this approach, some patients are able to benefit from these surgeries that only require three to five incisions the size of keyholes. Having smaller external cuts instead of a large open incision often means less pain and fewer complications after surgery. This approach also speeds up recovery.

For the right patient, DHI colon and rectal surgeons can use minimally invasive approaches to treat:

Colorectal Surgery Procedures at DHI

Colorectal surgery most often involves removing the diseased or injured part of the colon or rectum. Then a new path for stool to exit from the body must be created. Many colorectal procedures create a need for a permanent or temporary ostomy. As much as possible, DHI’s colon and rectal surgeons use the J-pouch procedure, a type of ostomy that eventually allows stool to exit via the anus as usual. DHI surgeons also opt for procedures that spare a patient’s sphincter muscle, which prevents the need for a permanent ostomy.

Broadly speaking, the main forms of colorectal surgery are colectomy and abdominoperineal resection.

Colectomy (Bowel Resection)

A colectomy is a surgery that removes all or part of the colon, or large intestine. It is also called a bowel resection.

Colectomy can treat the following conditions:

  • Colon cancer
  • Rectal cancer
  • Crohn’s disease (when other treatments have not worked)
  • Familial adenomatous polyposis (genetic condition that leads to a history of pre-cancerous colon polyps)
  • Lynch syndrome (genetic inheritance of an increased risk for colon and other abdominal cancers)
  • Ulcerative colitis (when other treatments have not worked)

Traditionally, a colectomy is an open procedure performed through one large incision, but for some conditions and patients, DHI colorectal surgeons can offer a minimally invasive approach.

Whenever a colectomy is performed, an ostomy procedure to redirect waste through the intestines will be needed. DHI surgeons can sometimes use a J-pouch surgery alternative so stool will be able to exit through the anus.

Abdominoperineal Resection (APR)

An abdominoperineal resection, what surgeons refer to as an APR, involves removing the anus, rectum, and part of the sigmoid (lowest) colon. If an APR is being used to treat cancer, sometimes nearby lymph nodes are also removed. This is called total mesorectal excision.

APR can be used to treat:

At the Digestive Health Institute, whenever possible our colon and rectal surgeons offer minimally invasive surgery for APR. It can be done as robotic-assisted surgery. While APR is still a major surgery, having it as a minimally invasive procedure speeds up recovery.

Sphincter-Preserving Approaches to Rectal Surgery

An APR removes the sphincter muscle around the anal canal. This leaves patients with a need for a permanent colostomy. So that more patients can avoid this, our colon and rectal surgeons explore other surgical options for patients who are referred to them for an APR. Sometimes a patient can have a sphincter-preserving surgery such as an extended low anterior resection (LAR) instead. This approach leaves enough of the anus so that the sphincter muscle can work as usual. There may be drawbacks as well as benefits to a less involved surgery, so our surgeons can help you explore all of your options.
