Surgery for Colon and Rectal Cancer Colon and Rectal Surgery Mohammed Bayasi, MD Department of Surgery Colon and Rectal Surgery What is a Colon and Rectal Surgeon? • Fully trained General Surgeon. • Has done additional training in the diseases of colon and rectum. Why Colon and Rectal Surgery? • Surgical and non surgical therapy for multiple diseases. • Chance to help cancer patients by removing tumor, potentially curing them. • Variety of cases, ages and patient populations. • Specialized area. Colorectal Diseases • Colon • Rectum/Anus – Cancer – Hemorrhoids – Diverticulitis – Anal fistula and – Inflammatory Bowel abscess Disease (Crohn, UC) – Anal fissure – Polyps – Prolapse Symptoms/Signs • Pain • Itching • Discharge • Bleeding • Lump Anatomy Lesson Colon • Extracts water and nutrients. • Helps to form and excrete waste. • Stores important bacteria flora. • Length: 1.5 meters long = 4.9 feet = 59 inches Colon Rectum/Anus • The final portion of the colon. • Area contains muscles important in controlling defecation and flatulence. Rectum/Anus When to see a Colon and Rectal Surgeon • Referral from another physician (Gastroenterology, PCP). • Treatment of anorectal diseases. • Blood with stool, abdominal pain, rectal pain. Hemorrhoids • Internal and external. • Cushions of blood vessels. • When enlarged, they cause bleeding and pain. Treatment • Treatment of symptomatic hemorrhoids is directed by the symptoms themselves. It can broadly be categorized into four groups: − Medical therapy − Office-based procedure − Operative therapies − Emergent interventions Anorectal Abscess • It is a collection of pus in the perianal area. Normal • Causes pain and rectal gland drainage, and if it progresses, fever and systemic Abscess infection. • Treated with incision and drainage. Anorectal Fistula • A tunnel between the inside of the anus and the skin. • Causes discharge, pain, and formation of abscess. • Multiple surgical options depending on fistula complexity. Abdominal Surgery • Colectomy: removal of part or all of the colon • Low Anterior Resection (LAR): removing the lower portion of the colon, the rectum by making an abdominal incision • Abdominoperineal Resection (APR): removing the rectum and anus. Right hemicolectomy Left hemicolectomy Transverse colectomy Sigmoid colectomy A colectomy may be done anywhere within the shaded areas of the diagrams. Right Colon Resection Ostomy • An opening of the intestinal tract at the level of the skin. • Allows passage of stool or enteric content. • Temporary or permanent. Colostomy Colostomy Minimally Invasive Surgery • Performed through small incisions • Less pain • Shorter hospital stay • Faster recovery Laparoscopic Laparoscopic Surgery Robotic Surgery • Minimally invasive surgery. • Improved visualization of tissues. • NOT artificial intelligent. Minimally Invasive Surgery • Laparoscopic: inside the abdominal cavity • Endoscopic: inside the colon or rectum Enhanced Recovery After Surgery • Decreases surgical stress through evidence based measures. • Results – Less complications – Improved “well being” state – Faster recovery Bloodless Surgery • Optimizing blood level prior to surgery. • Using state-of-the-art technologies to minimize blood loss. • Minimally invasive surgery. • Enhanced recovery after surgery.

    Medical Policy 7.01.123 Plugs for Anal Fistula Repair Original Policy Date: November 26, 2014 Effective Date: January 1, 2021 Section: 7.0 Surgery Page: Page 1 of 12 Policy Statement Biosynthetic fistula plugs, including plugs made of porcine small intestine submucosa or of synthetic material, are considered investigational for the repair of anal fistulas. NOTE: Refer to Appendix A to see the policy statement changes (if any) from the previous version. Policy Guidelines There is a specific CPT code for the use of these plugs in the repair of an anorectal fistula: • 46707: Repair of anorectal fistula with plug (e.g., porcine small intestine submucosa [SIS]) Description Anal fistula plugs (AFPs) are biosynthetic devices used to promote healing and prevent the recurrence of anal fistulas. They are proposed as an alternative to procedures including fistulotomy, endorectal advancement flaps, seton drain placement, and use of fibrin glue in the treatment of anal fistulas. Related Policies • N/A Benefit Application Benefit determinations should be based in all cases on the applicable contract language. To the extent there are any conflicts between these guidelines and the contract language, the contract language will control. Please refer to the member's contract benefits in effect at the time of service to determine coverage or non-coverage of these services as it applies to an individual member. Some state or federal mandates (e.g., Federal Employee Program [FEP]) prohibits plans from denying Food and Drug Administration (FDA)-approved technologies as investigational. In these instances, plans may have to consider the coverage eligibility of FDA-approved technologies on the basis of medical necessity alone.

It has long been recognized that anal lesions may precede intestinal Crohn's disease, often by some years, but the specific characteristics of the lesion have not hitherto been described. The differential diagnosis is discussed in detail. In a previous report from this hospital (Morson and types of anal lesion when the patients were first seen Lockhart-Mummery, 1959) the clinical features and were as follows: pathology of the anal lesions of Crohn's disease were described.

  • Anal Fistula
    ANAL FISTULA This leaflet is produced by the Department of Colorectal Surgery at Beaumont Hospital supported by an unrestricted grant to better Beaumont from the Beaumont Hospital Cancer Research and Development Trust. This information leaflet has been designed to give you general guidelines and advice regarding your surgery. Not all of this information may be relevant to your circumstances. Please discuss any queries with your doctor or nurse. YOUR TREATMENT EXPLAINED What is a fistula? A fistula is a small tract or tunnel between the back passage and the external skin on the buttocks. This is usually the result of a previous abscess which has drained but which has not fully healed. This results in an intermittent or persistent discharge or leaking of pus or blood. Once a tract has been formed it will remain in place as long as there is pus draining through it. There are different types of fistula. Some develop as a single tract from your rectum (back passage) through to the external skin (simple fistula). Others may branch of into different directions creating more than one tract (complex fistula). How can a fistula be treated? Treatment for a fistula varies from person to person depending on the type of fistula and how each individual fistula responds following surgery. Most of these procedures are carried out as a day case procedure. You will come to the Day ward on the morning of your procedure. You will usually be able to go home the same day once you have recovered from your anaesthetic. The aim of treating a fistula is to drain away any pus allowing inflammation to settle and ultimately the tract to heal.

  • Funding Research to Fight Diseases of the Gut, Liver & Pancreas
    FUNDING RESEARCH TO FIGHT DISEASES OF THE GUT, LIVER & PANCREAS THE DIGESTIVE SYSTEM THIS FACTSHEET IS ABOUT ANAL FISTULAS An anal fistula is a channel that develops between the end of the bowel and the skin near the anus. CAUSES WHAT IS THE CAUSE OF ANAL FISTULAS? Anal fistulas are normally caused by an infection around the anus. The infection causes a build-up of pus (abscess) that leaves a channel behind when it has drained away. The channel (fistula) persists causing symptoms of pain and irritation, smelly discharge from near the anus that can look like pus or blood, and painful swellings (abscesses). The end of the fistula may be visible as a hole or small lump in the skin close to the anus. More rarely a fistula develops due to other medical conditions such as Crohn’s disease (a type of inflammatory bowel disease), hidradenitis suppurativa (a skin condition), infection with tuberculosis (TB) or HIV, or following radiotherapy or chemotherapy cancer treatment. A fistula is a channel (or sinus) between the end of the bowel (anus or rectum) and the skin near the anus (as in this image.) DIAGNOSIS HOW ARE FISTULAS DIAGNOSED? Your doctor will examine you and ask about your symptoms. Some fistulas can be easy to see but others might need to be identified by using an MRI or specialist ultrasound scan to see where the tract is. HOW CAN ANAL FISTULAS AFFECT YOU? An anal infection or abscess is quite common and does not always lead to a fistula. Fistulas may result in pain, itching and a smelly discharge.

COLORECTAL/ANORECTAL SURGERY, COLONOSCOPY, ANORECTAL PHYSIOLOGY (703) 280-2841 DISCHARGE INSTRUCTIONS AFTER FISTULOTOMY An anal fistula is an abnormal channel or tunnel-like chronic infection that starts inside the anus and ends outside on the skin around the anus. Its development is usually the result of a previous anal infection or abscess. About 50% of people with an anal abscess end up with a fistula. Most fistulas are short and superficial and are best treated by simply opening the entire tunnel and leaving it open to heal in gradually. Occasionally a patient can have a complex fistula with multiple tracts or the tunnel may traverse a considerable amount of the sphincter muscle. For this reason the surgical treatment has to be individualized for each particular patient depending on the location and anatomy of the fistula. Frequently, the surgeon cannot guarantee exactly what will need to be done until the examination that is done under anesthesia at the time of the surgery. It is important to realize that the operative procedure can change depending on what is found at the time of the surgery. At times a fistula will require more than one surgery to cure.
