The Roux-en-Y Gastric Bypass Dallas – often called Gastric Bypass Dallas – is considered the ‘gold standard’ of weight loss surgery.

The Procedure

There are two components to the procedure. First, a small stomach pouch, approximately one ounce or 30 milliliters in volume, is created by dividing the top of the stomach from the rest of the stomach.

Most importantly, the rerouting of the food stream produces changes in gut hormones that promote satiety, suppress hunger, and reverse one of the primary mechanisms by which obesity induces type 2 diabetes.

Advantages

1. Produces significant long-term weight loss (60 to 80 percent excess weight loss)
2. Restricts the amount of food that can be consumed
3. May lead to conditions that increase energy expenditure
4. Produces favorable changes in gut hormones that reduce appetite and enhance satiety
5. Typical maintenance of >50% excess weight loss

Disadvantages

1. Is technically a more complex operation than the AGB or LSG and potentially could result in greater complication rates
2. Can lead to long-term vitamin/mineral deficiencies particularly deficits in vitamin B12, iron, calcium, and folate
3. Generally has a longer hospital stay than the AGB
4. Requires adherence to dietary recommendations, life-long vitamin/mineral supplementation, and follow-up compliance

The Laparoscopic Sleeve Gastrectomy Dallas – often called the sleeve – is performed by removing approximately 80 percent of the stomach. The remaining stomach is a tubular pouch that resembles a banana.

The Procedure

This procedure works by several mechanisms. First, the new stomach pouch holds a considerably smaller volume than the normal stomach and helps to significantly reduce the amount of food (and thus calories) that can be consumed.

Short term studies show that the sleeve is as effective as the roux-en-Y gastric bypass in terms of weight loss and improvement or remission of diabetes.  The complication rates of the sleeve fall between those of the Adjustable Gastric Band Dallas and the roux-en-y gastric bypass.

Advantages

1. Restricts the amount of food the stomach can hold
2. Induces rapid and significant weight loss that comparative studies find similar to that of the Roux-en-Y gastric bypass. Weight loss of >50% for 3-5+ year data, and weight loss comparable to that of the bypass with maintenance of >50%
3. Requires no foreign objects (AGB), and no bypass or re-routing of the food stream (RYGB)
4. Involves a relatively short hospital stay of approximately 2 days
5. Causes favorable changes in gut hormones that suppress hunger, reduce appetite and improve satiety

Disadvantages

1. Is a non-reversible procedure
2. Has the potential for long-term vitamin deficiencies
3. Has a higher early complication rate than the AGB

The Adjustable Gastric Band Dallas – often called the band – involves an inflatable band that is placed around the upper portion of the stomach, creating a small stomach pouch above the band, and the rest of the stomach below the band.

The Procedure

The common explanation of how this device works is that with the smaller stomach pouch, eating just a small amount of food will satisfy hunger and promote the feeling of fullness. The feeling of fullness depends upon the size of the opening between the pouch and the remainder of the stomach created by the gastric band. The size of the stomach opening can be adjusted by filling the band with sterile saline, which is injected through a port placed under the skin.

The clinical impact of the band seems to be that it reduces hunger, which helps the patients to decrease the amount of calories that are consumed.

Advantages

1. Reduces the amount of food the stomach can hold
2. Induces excess weight loss of approximately 40 – 50 percent
3. Involves no cutting of the stomach or rerouting of the intestines
4. Requires a shorter hospital stay, usually less than 24 hours, with some centers discharging the patient the same day as surgery
5. Is reversible and adjustable
6. Has the lowest rate of early postoperative complications and mortality among the approved bariatric procedures
7. Has the lowest risk for vitamin/mineral deficiencies

Disadvantages

1. Slower and less early weight loss than other surgical procedures
2. Greater percentage of patients failing to lose at least 50 percent of excess body weight compared to the other surgeries commonly performed
3. Requires a foreign device to remain in the body
4. Can result in possible band slippage or band erosion into the stomach in a small percentage of patients
5. Can have mechanical problems with the band, tube or port in a small percentage of patients
6. Can result in dilation of the esophagus if the patient overeats
7. Requires strict adherence to the postoperative diet and to postoperative follow-up visits

The Biliopancreatic Diversion with Duodenal Switch Dallas  – abbreviated as BPD/DS – is a procedure with two components. First, a smaller, tubular stomach pouch is created by removing a portion of the stomach, very similar to the sleeve gastrectomy.

The Procedure

The duodenum, or the first portion of the small intestine, is divided just past the outlet of the stomach. Roughly three-fourths of the small intestine is bypassed by the food stream.

Lastly, the BPD/DS, similar to the gastric bypass and sleeve gastrectomy, affects guts hormones in a manner that impacts hunger and satiety as well as blood sugar control. The BPD/DS is considered to be the most effective surgery for the treatment of diabetes among those that are described here.

Advantages

1. Results in greater weight loss than RYGB, LSG, or AGB, i.e. 60 – 70% percent excess weight loss or greater, at 5 year follow up
2. Allows patients to eventually eat near “normal” meals
3. Reduces the absorption of fat by 70 percent or more
4. Causes favorable changes in gut hormones to reduce appetite and improve satiety
5. Is the most effective against diabetes compared to RYGB, LSG, and AGB

Disadvantages

1. Has higher complication rates and risk for mortality than the AGB, LSG, and RYGB
2. Requires a longer hospital stay than the AGB or LSG
3. Has a greater potential to cause protein deficiencies and long-term deficiencies in a number of vitamin and minerals, i.e. iron, calcium, zinc, fat-soluble vitamins such as vitamin D
4. Compliance with follow-up visits and care and strict adherence to dietary and vitamin supplementation guidelines are critical to avoiding serious complications from protein and certain vitamin deficiencies

Laparoscopic Dallas gastric banding is surgery to help with weight loss. The surgeon places a band around the upper part of your stomach to create a small pouch to hold food. The band limits the amount of food you can eat by making you feel full after eating small amounts of food.

After surgery, your doctor can adjust the band to make food pass more slowly or quickly through your stomach.

Description

You will receive general anesthesia before this surgery. You will be asleep and unable to feel pain.

The surgery is done using a tiny camera that is placed in your belly. This type of surgery is called laparoscopy. The camera is called a laparoscope dallas. It allows your surgeon to see inside your belly. In this surgery:

• Your surgeon will make 1 to 5 small surgical cuts in your abdomen. Through these small cuts, the surgeon will place a camera and the instruments needed to perform the surgery.
• Your surgeon will place a band around the upper part of your stomach to separate it from the lower part. This creates a small pouch that has a narrow opening that goes into the larger, lower part of your stomach.
• The surgery does not involve any cutting or stapling inside your belly.
• Your surgery may take only 30 to 60 minutes if your surgeon has done a lot of these procedures.

When you eat after having this surgery, the small pouch will fill up quickly. You will feel full after eating just a small amount of food. The food in the small upper pouch will slowly empty into the main part of your stomach.

Most gastrointestinal stromal tumors (GISTs) occur in the stomach or small intestine. These tumors often grow into the empty space inside the gastrointestinal (GI) tract, so they might not cause symptoms right away unless they are in a certain location or reach a certain size.

Small tumors might not cause any symptoms and may be found accidentally when the doctor is looking for some other problem. These small tumors often grow slowly.

Symptoms related to blood loss

GISTs tend to be fragile tumors that can bleed easily. In fact, they are often found because they cause bleeding into the GI tract. Signs and symptoms of this bleeding depend on how fast it occurs and where the tumor is located.

• Brisk bleeding into the esophagus or stomach can cause the person to throw up blood. When the blood is thrown up it may be partially digested, so it might look like coffee grounds. 
• Brisk bleeding into the stomach or small intestine can make bowel movements (stools) black and tarry.
• Brisk bleeding into the large intestine is likely to turn the stool red with visible blood.
• If the bleeding is slow, it often doesn’t cause the person to throw up blood or have a change in their stool. Over time, though, slow bleeding can lead to a low red blood cell count (anemia), and make a person feel tired and weak.

Bleeding from the GI tract can be very serious. If you have any of these signs or symptoms, see a doctor right away.

Other possible symptoms of GISTs

Other symptoms of GISTs can include:

• Abdominal (belly) pain
• A mass or swelling in the abdomen
• Nausea, vomiting
• Feeling full after eating only a small amount of food
• Loss of appetite
• Weight loss
• Problems swallowing (for tumors in the esophagus)

Sometimes the tumor grows large enough to block the passage of food through the stomach or intestine. This is called an obstruction, and it can cause severe abdominal pain and vomiting.

If your colon cancer Dallas is very small, your doctor may recommend a minimally invasive approach to surgery, such as:

Removing polyps during a colonoscopy (polypectomy). 

If your cancer is small, localized, completely contained within a polyp and in a very early stage, y.our doctor may be able to remove it completely during a colonoscopy.

Endoscopic mucosal resection. 

Larger polyps might be removed during colonoscopy using special tools to remove the polyp and a small amount of the inner lining of the colon in a procedure called an endoscopic mucosal resection.

Minimally invasive surgery (laparoscopic surgery). 

Polyps that can’t be removed during a colonoscopy may be removed using laparoscopic surgery. In this procedure, your surgeon performs the operation through several small incisions in your abdominal wall, inserting instruments with attached cameras that display your colon on a video monitor.

Screening colon cancer Dallas

Doctors recommend that people with an average risk of colon cancer Dallas consider colon cancer Dallas screening around age 50. But people with an increased risk, such as those with a family history of colon cancer Dallas, should consider screening sooner.

Several screening options exist — each with its own benefits and drawbacks. Talk about your options with your doctor, and together you can decide which tests are appropriate for you.

Lifestyle changes to reduce your risk of colon cancer Dallas

You can take steps to reduce your risk of colon cancer Dallas by making changes in your everyday life. Take steps to:

Eat a variety of fruits, vegetables and whole grains. 

Fruits, vegetables and whole grains contain vitamins, minerals, fiber and antioxidants, which may play a role in cancer prevention.

Drink alcohol in moderation, if at all. 

If you choose to drink alcohol, limit the amount of alcohol you drink to no more than one drink a day for women and two for men.

Stop smoking. 

Talk to your doctor about ways to quit that may work for you.

Exercise most days of the week. 

Try to get at least 30 minutes of exercise on most days. If you’ve been inactive, start slowly and build up gradually to 30 minutes.

Factors that may increase your risk of colon cancer include:

Older age. 

Colon cancer can be diagnosed at any age, but a majority of people with colon cancer are older than 50. The rates of colon cancer in people younger than 50 have been increasing, but doctors aren’t sure why.

African-American race. 

African-Americans have a greater risk of colon cancer than do people of other races.

A personal history of colorectal cancer or polyps.

 If you’ve already had colon cancer or noncancerous colon polyps, you have a greater risk of colon cancer in the future.

Inflammatory intestinal conditions. 

Chronic inflammatory diseases of the colon, such as ulcerative colitis and Crohn’s disease, can increase your risk of colon cancer.

Inherited syndromes that increase colon cancer risk. 

Some gene mutations passed through generations of your family can increase your risk of colon cancer significantly. Only a small percentage of colon cancers are linked to inherited genes.

Family history of colon cancer. 

You’re more likely to develop colon cancer if you have a blood relative who has had the disease. If more than one family member has colon cancer or rectal cancer, your risk is even greater.

Low-fiber, high-fat diet. 

Colon cancer and rectal cancer may be associated with a typical Western diet, which is low in fiber and high in fat and calories. Research in this area has had mixed results. Some studies have found an increased risk of colon cancer in people who eat diets high in red meat and processed meat.

A sedentary lifestyle. 

People who are inactive are more likely to develop colon cancer. Getting regular physical activity may reduce your risk of colon cancer.

Diabetes. 

People with diabetes or insulin resistance have an increased risk of colon cancer.

Obesity.

People who are obese have an increased risk of colon cancer and an increased risk of dying of colon cancer when compared with people considered normal weight.

Smoking. 

People who smoke may have an increased risk of colon cancer.

Alcohol. 

Heavy use of alcohol increases your risk of colon cancer.

Radiation therapy for cancer. 

Radiation therapy directed at the abdomen to treat previous cancers increases the risk of colon cancer.

Signs and symptoms of colon cancer include:

• A persistent change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool
• Rectal bleeding or blood in your stool
• Persistent abdominal discomfort, such as cramps, gas or pain
• A feeling that your bowel doesn’t empty completely
• Weakness or fatigue
• Unexplained weight loss

Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they’ll likely vary, depending on the cancer’s size and location in your large intestine.
