What are Different Types of Bariatric Surgeries? 

Bariatric Surgery is one of the most popular options for obese people looking for a way to control their weight. To get bariatric surgery, one has to qualify for certain criteria like BMI (Body Mass Index), associated comorbidities like Diabetes, Hypertension, sleep apnea, infertility, hypercholesterolemia etc. There are many kinds of bariatric surgeries or weight loss surgeries, different surgeries work differently in order to give the desired effect, which is why it is important to understand these surgeries thoroughly. 

Weight loss surgeries are divided into different categories like - 

  Restrictive surgeries: Some bariatric surgeries are focused on limiting the amount of food that can be stored in the stomach. This allows a person to eat less than they used to, because of the limited capacity of the stomach. Sleeve gastrectomy, Adjustable gastric banding, Gastric imbrication, Gastric balloon surgery are examples of restrictive procedures. In sleeve gastrectomy, the stomach is divided into two halves first, then one half of the stomach is completely removed. The remaining part of the stomach is formed into a tube-like structure. This tube-like structure cannot hold enough food and restricts excessive food intake. It also limits the secretion of an appetite hormone called Ghrelin which limits the desire of a person to eat. 

  Malabsorptive procedures: In this procedure, a large segment of the small intestine is bypassed i.e the food is not allowed to enter a large segment of the small intestine and hence malabsorption will be there. Duodenal switch is a malabsorbtive surgery. 

To Summarize: The weight loss procedures that suit our Indian population are the Roux en Y gastric bypass and the sleeve gastrectomy. We do not come across any sign of malnutrition in patients who have undergone these procedures. For successful outcomes, vitamin, calcium and protein supplements are required. 

There are certain myths about bariatric surgery --- life will never be normal after the surgery, pregnancy is a problem after this surgery, one will never be able to eat after this surgery, marriage is a problem after this surgery etc. All these are incorrect as one live a better life after the surgery as one has shed the extra kilos, one is cured of existing problems like diabetes, high cholesterol, hypertension, obesity induced infertility and sleep apnea extra. IN FACT, the quality of life is phenomenal after this surgery. CHOICE of surgery depends on the existing BMI, existing associated problems and results of the investigations that are done prior to the surgery. Your surgeon is the best to decide the right procedure for you. As the procedure which your friend has undergone might not be good for you. Choice of procedure and proper follow up are the key points for a successful surgical outcome. 

  Combination of restrictive and Malabsorptive surgeries: In these procedures, the surgery is done on the stomach as well as the small intestine. It involves creating a small stomach pouch which is attached to the small intestine, thus bypassing a small segment of the small intestine to get the desired effect if the person has diabetes associated. The rest of the stomach produces important digestive juices and is also connected to the intestine so that it can transfer these digestive juices in it. As a part of the stomach and few centimetres of the small intestine are bypassed i.e food does not enter this part, the surgery is called the gastric bypass. The Roux en Y gastric bypass and the Mini Gastric bypass surgeries are examples of these combination procedures.

Colorectal surgery: How to be sure you need it?

Colorectal surgery is performed to repair damages that occur in the organs of the anus, rectum, and colon. The damage that takes place in these organs can be the result of problems with lower GI like diverticulitis (a condition wherein pouches known as diverticula in the colon wall become inflamed), cancer and inflammatory bowel disease (a group of intestinal disorders that bring about inflammation of the GI).

Who needs this surgery?

In general, colorectal surgery is an essential treatment option for ulcerative colitis, colorectal cancer, Crohn's disease (an inflammatory bowel disease that gives rise to inflammation of the gastrointestinal tract) as well as certain diverticulitis cases. In such cases, the intestinal tract undergoes major reconstruction.

There are also other bowel problems that may require surgery but not of a serious nature and these are anal fissures, hemorrhoids, bowel incontinence and rectal prolapse. Most of the surgical procedures will aid in repairing tears, get rid of blockages, or make tighter sphincter muscles (muscles that surround openings in the body).

Colorectal surgery is also performed in cases of pelvic floor disorders like rectocele (a condition in which the rectum bulges towards the vagina) and perineal hernia (a hernia that involves the pelvic floor).

At the same time, injury, ischemia or compromised blood supply and obstruction may require the performance of bowel surgery as well. Scar tissue and masses can form within the rectum, clogging the organ and preventing the normal discharge of feces from the body.

Problems like ulcerative colitis (an inflammatory bowel disease that leads to the development of ulcers in the colon as well as inflammation of the area) and diverticulitis can give rise to perforations in the rectum. Surgery is suggested in instances when drugs fail to treat the problem of ulcerative colitis.

Likewise, in the case of recurrent instances of perforations or complications in diverticulitis, surgery may be required to remove the portion of the colon affected.



Colorectal Surgery: How To Be Sure You Really Need it

Are you overweight and thinking about undergoing a weight loss surgery? If yes, then you can opt for a gastric bypass surgery in which certain changes are made to your digestive system. Due to these changes, the amount of food you consume gets limited and the absorption of nutrients also gets reduced. Hence, weight is lost due to a reduced appetite or stomach capacity. This surgery is undertaken by people who face severe health difficulties because of being overweight. Gastric bypass surgery is a very common form of weight loss surgery associated with fewer complications.

Why is it carried out?
A gastric bypass surgery is carried out to help you lose excess weight. This reduces the risk of several weight related health problems such as heart diseases, hypertension, severe sleep apnea, strokes, type 2 diabetes and gastroesophageal reflux disease. This surgery is undertaken when a person fails to lose weight after following several other methods.

Who is it for?
You can undergo a gastric bypass surgery only when your body mass index or BMI is 40 or higher, or when your BMI is between 35 to 39.9 and you also have a severe condition such as type 2 diabetes or high blood pressure. This surgery is not for all people who are overweight and several criteria have to be fulfilled before deciding on getting a gastric bypass surgery.

Procedure
This surgery has to be carried out at a hospital and the patient is given general anesthesia. The surgery depends on the individual situation of the patient and on the surgeon who will perform the surgery. Most bariatric or gastric bypass surgeries are carried out laparoscopically. A laparoscope, which is a small, tubular device with a camera attached to it, is inserted into the abdomen via small incisions. The camera allows the surgeon to see the inside your abdomen and perform the procedure. A laparoscopic surgery is efficient and the patient recovers faster than other modes of surgery. The surgery takes several hours to be successfully completed. The patient may have to stay at the hospital for five days.

Results
Gastric bypass surgery or bariatric surgery provides long-term weight loss. The amount of weight that will be lost depends on the surgical procedure and the patient s new lifestyle and habits. It is possible to lose more than 50% of the pre-surgery body weight within a span of two years. Along with weight loss, the surgery also improves and resolves various conditions related to obesity.

A gastric bypass surgery also improves a patient s ability to undertake regular activities. This improves the quality of life and the patient gains confidence and self-esteem. A successful gastric bypass surgery can change your life.

Gastric Bypass Surgery - Who Can Go For It?

Any kind of injury on the surface of the skin is immediately noticed by us, but when something happens to one of our internal organs, it can take a little longer to get to your notice for example, an obstruction in the bile duct. The bile duct is a tubular structure responsible for carrying bile from the liver and gall bladder through the pancreas to the small intestine. This bile helps the digestion process and the absorption of fat.

An obstruction in the bile duct can be triggered by a number of factors. Some of these are:

    Gallstones
    Inflammation of the bile ducts
    Cysts
    Traumatic accidents
    Bile duct or pancreatic tumors
    Hepatitis infections
    Cirrhosis or severe liver damage
    Abnormal narrowing of the bile duct

This can affect anyone, but the people who have a history of gall stones or tumors in the abdomen are at a higher risk of suffering from bile duct obstruction. Chronic pancreatitis, sudden weight loss or obesity can also increase this risk. The symptoms of biliary obstruction include light coloured stool, dark urine, pain in the upper right abdomen, nausea, vomiting and fever. Your doctor will also probably need an X-ray of the bile ducts, blood tests, a hepatobiliary iminodiacetic acid scan and ultrasonograph to confirm a diagnosis before they can start treating you for the same.

If not treated in time, bile duct blockages can lead to a dangerous buildup of bilirubin in the body and trigger a number of life threatening diseases. Treatment for biliary obstruction can be through medication or surgery with surgery being the more preferred mode of treatment. It is aimed at resolving the underlying cause of the obstruction and alleviating the blockage. Treatment for biliary obstruction can be two common forms of treatment include a cholecystectomy and ERCP. The former involves the removal of the gall bladder and is suited to obstructions caused by gallstones. The latter is a procedure to remove small stones from the bile duct or place a stent inside the duct.

There are many ways bile duct obstruction can be prevented which first and foremost includes following a healthy lifestyle. If you are overweight, exercise for at least half an hour a day to regulate your weight and reach a healthy BMI. Decrease your intake of sugar and saturated fats as both these can cause gall stones. Also, increase the amount of fibre in your diet. All the above mentioned tips will certainly help you in preventing bile duct obstruction.

Bile Duct Blockage -  8 Factors Behind it!

Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.

Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.

Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.

A genetic test to predict cancer 10-11 years ahead of time
This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.

A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.

A simple blood test to predict breast cancer 5 years before it develops
This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.

It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics.

Can Breast Cancer Be Predicted Before It Develops?

Colorectal cancer is otherwise known as cancer of the colon or the rectum. This can affect both men and women with age being a major risk factor. Majority of such cancers are seen to occur after age of 50 years.

Type: colorectal cancers can present as one of the following types: 

Adenocarcinomas are the most common type of colorectal cancers. These cancers begin in the cells making mucous and other fluids. Certain colorectal cancers begin as adenomatous polyps (adenomas) that turn cancerous over a period of time. This is precisely why the adenomas are regarded as pre-cancerous or pre-malignant.

Gastrointestinal (GI) carcinoid tumors, GI stromal tumors, primary colorectal lymphoma, leiomyosarcoma, melanoma & squamous cell carcinoma are certain other colorectal cancers

Carcinoid tumors: start in specialized cells that produce hormones, in the intestine.

GI Stromal tumors: start in the interstitial cells of Cajal (ICC), in the wall of the colon.

Lymphomas: start typically in the lymph nodes but they may also start in colon or rectum.

Sarcomas: can start in the muscle and the connective tissue in the walls of the colon and rectum.

Gender: it affects both male and female populace.

Etiology: mostly, the factors that are associated with increased risk of colorectal cancer include the following  

Age exceeding 50 years.

Racial & ethnic background such as African Americans, in the USA, are known to have the highest incidence of colorectal cancer, and mortality rates.

Low fibre and high fat diet. Excessive consumption of red meat (e.g. goat meat, beef, pork, lamb, or liver), processed meats, butter, refined grains, sweets, sugary drinks etc all can increase the risk of colorectal cancer.

Personal history of inflammatory bowel disease (IBD) (e.g. ulcerative colitis), Crohn s disease, adenomatous colorectal polyps, colorectal cancer etc all.

Family history of colorectal cancer or adenomatous polyps etc all.

Inherited syndromes such as familial adenomatous polyposis (FAP) and Lynch syndrome (hereditary non-polyposis colon cancer or HNPCC).

Sedentary lifestyle/ associated Obesity.

Type 2 diabetes.

Tobacco and alcohol abuse.

Features or symptoms can vary from person to person depending on the size and location of the tumour. Following are the signs & symptoms mainly -

Changes in bowel habits, diarrhea or constipation or an alternating diarrhea and constipation.

Occult/ blood in the stool, and 

Problems related to blood loss (e.g. anemia, weakness, fatigue, intolerance to exercise, shortness of breath, increased heart rate, chest pain etc all),

Abdominal discomfort (frequent gas/ flatulence, bloating, fullness, cramps, and pain), vomiting etc.

Unexplained weight loss,

Pain with bowel movement,

Feeling that bowel does not empty completely,

Stools are narrower than usual.

Diagnosis: Following are the diagnostics employed. Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for accurate diagnosis.
Blood: fecal occult blood test, Carcinoembryonic Antigen (CEA) assay values are raised, Hb/ RBC counts may be low.
Imaging: Colonoscopy, Endorectal Scan/ CT Scan followed by Biopsy clinches the diagnosis and the nature of the disease.
Apart from the above-mentioned barium enema X-Ray, USG, Chest X-ray, PET CT scan etc all help detect metastasis, if any. An increase in level of the serum tumor marker  CEA  is indicative of metastatic spread/ proliferation that can be ascertained through a PET CT scan.
Treatment: Conventional treatment includes surgery, radiation and chemotherapy as contextually appropriate. Simultaneously, an adjunctive/ integrative naturopathic treatment with suitable complementary & alternative medicines (CAM)/ therapies too can help improve clinical outcomes and facilitate recovery as feasible contextually.
Prognosis: preventive measures, earlier diagnosis and right early treatment is key for better prognosis and efficient/ effective therapeutic management. Usually, the chances of cure for an early stage cancer are more. Above-mentioned apart, recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all too.

Prevention: rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an adherence to a Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising (for at least 30 minutes daily), de-stressing and relaxation is highly recommended for prevention or reducing the risks of colorectal cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. It is advisable to limit milk/ dairy, preferably of low fat content, to 1 to 2 servings max daily. Although alcohol is optional and is not for everyone, the consumption of the same, if any, has to be strictly in moderation, and is best avoided. Smoking is to be avoided as well. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly or are best avoided too. Apart from the generic preventive measures as mentioned above, certain pre-malignant conditions, of which adenomas are the most common, can be successfully treated with complementary and alternative medicines too.
