Colon and Rectal Surgery

There are many conditions affecting the colon and rectum, including both benign and malignant medical problems. Colorectal cancer, sometimes called colon cancer or rectal cancer, is one of most common cancers affecting men and women in the U.S. While this is a highly prevalent condition, more and more people have successfully been cured of their colorectal cancer over the years, due to an increase in screenings, early removal of colorectal polyps, and more effective treatments being developed.

What Are the Symptoms of Colorectal Cancer?

Many people who suffer from colon and/or rectal cancer experience little to no symptoms until it has reached a more advanced stage. This is why it is so important to undergo regular screenings to diagnose colorectal cancer at its earliest stages. Potential signs and symptoms of colorectal cancer include: 

• Change in bowel habits 
• Incomplete evacuation of stool
• Rectal bleeding or blood in stool
• Chronic discomfort in the abdomen, bloating or gas pains
• Feeling weak or fatigued
• Weight loss without a known cause
• Iron deficiency (anemia)

The best way to potentially cure colorectal cancer is to diagnose it in its early stages. The general population typically undergoes routine screening techniques, especially those with risk factors.
 

What Causes Colorectal Cancer?

There is no known cause of colorectal cancer, but the condition is believed to be connected to environmental and genetic factors. Most, but not all, colorectal cancers begin as benign polyps which are pre-malignant growths within the bowel wall. These benign polyps eventually can progress to cancer. The polyps are often identified on a colonoscopy. 

What Is a Colonoscopy?

A colonoscopy is an evaluation of the colon and rectum that is performed endoscopically. 

This screening test is typically recommended for adults 45 and older, every 10 years if results continue to be normal, which are new guidelines from the American Cancer Society. A colonoscopy may also be performed on people with symptoms of change in bowel habits, rectal bleeding, diarrhea or constipation and abdominal pain. Polyps that are identified can often be removed endoscopically, but if they are not amenable to endoscopic removals, they may require a surgical resection. Often, benign polyps can be removed with laparoscopic surgery or robotic surgery. Minimally invasive techniques utilizing the laparoscope allow for the colon to be removed and brought out through a small incision.

What Are the Different Types of Colon & Rectal Surgery?

• Rectal cancers and polyps require treatment that is tailored to the extent of disease present. Benign polyps and early cancers can often be removed transanally. When advanced cancers are identified, sphincter-preserving methods can often be utilized to preserve the patient’s anal continence. 
• Diverticular disease can involve recurrent bouts of abdominal pain, which is often crampy and associated with altered bowel habits. In addition, diverticular disease can involve rectal bleeding. Diverticulitis can occur and cause severe pain, fever, chills, change in bowel habits, and even perforation, abscess, or fistula formation. If diverticular disease is severe enough to require surgery, the procedure often can be performed with minimally invasive techniques. Laparoscopic colon resections can be performed for diverticular disease, decreasing the postoperative pain, time of hospitalization and recovery time.
• Inflammatory bowel disease often requires surgical intervention. These resections often are used for Crohn’s disease secondary to chronic obstruction of the bowel, fistula formation, and bleeding. 

How Is Colon & Rectal Surgery Performed?

In the past, colorectal surgery required open incisions and resulted in long hospital stays for the patient, as well as a prolonged recovery period of time. Our surgical team performs minimally invasive colorectal surgery through laparoscopic and robotic techniques. These methods allow our surgeons to offer procedures that were not easily performed otherwise in the past. They ultimately lead to less postoperative pain, faster healing time, decreased hospital stay, decreased recovery time and less of a risk of developing an abdominal wall hernia as a result of the surgery.

Laparoscopic Colorectal Surgery

Minimally invasive laparoscopic colorectal surgery may be recommended in order to treat many disorders that require removal of a portion of the large intestine. These conditions include benign colorectal polyps not amenable to endoscopic removal, malignant polyps, colorectal cancers, diverticular disease, rectal prolapse as well as others. In addition to laparoscopic colorectal surgery, a newer option is also available in order to accomplish the procedures in a minimally invasive manner. 

Robotic Colorectal Surgery

Performing minimally invasive colorectal surgery with the da Vinci^® robotic system has many advantages. This advanced technology features the use of a magnified 3D HD vision system and special wristed instruments that bend and rotate far greater than the human hand. The da Vinci^® robotic technology enables a surgeon to operate with enhanced vision, precision and control. The ability to work in the pelvis with improved visualization and access is dramatic with respect to the use of the robotic system. This allows the surgeon a better ability to preserve the anal sphincter in low rectal cancers in particular. In addition, the da Vinci^® robotic system offers integrated fluorescence imaging which allows a surgeon to assess the blood supply of the colon and rectum that they are going to connect during an operation.
