Pancreatic Cancer

Pancreas is an important endocrine organ which is located behind the stomach. It plays a vital roe in the process of digestion as it produces ‘enzymes’. The enzymes help the body in digestion of fats, proteins and carbohydrates.

What is Pancreatic Cancer?

An abnormal growth of the cells in the pancreas can lead to pancreatic cancer. It occurs within the pancreas tissues and because of this, it can be a little difficult to detect pancreatic cancer. In most cases, the patients do not show any serious symptoms, but just some subtle signs that include:

  •  Pain in the stomach
  •  Loss of appetite
  •  Blood clots
  •  Unexplained loss in weight
  •  Depression
  •  Jaundice

What are the Causes of Pancreatic Cancer?

The exact reason that can lead to pancreatic cancer is still unknown, however it has been established that when cells in the pancreas start to grow at an unusual rate, it can lead to cancer of the pancreas.

All cells have a life circle and the grow and expire in proportion, but sometimes over production of cells makes the old and damaged cells take over the healthy ones leading to infections and thus cancer.

What are the Treatments Available for Pancreatic Cancer?

A great deal of the treatment depends on the stage of cancer as well as the condition the patient is in. However, every treatment has two main objectives:

  • Getting rid of the cells that are cancerous
  • Preventing the spread of this disease

The available options for treatment are:

  • Radiation Therapy

X-rays and high-energy beams are used to kill the cancerous cells, and stop their spread to the rest of the body.

  • Chemotherapy

Using cancer-killing medications the future growth of cells can be contained.

  • Targeted Therapy

Certain drugs that are specially designed to destroy only the cancer cells, work very well without harming the healthy cells.

  • Surgery

Though a surgery is generally taken as the last option, it depends on the stage at which the cancer has reached. With a surgical procedure a part or parts or the whole pancreas may be removed. There are many factors that your doctor and surgeon will bear in mind before advising a surgery.

Is Pancreatic Cancer Curable?

Yes, it is. However, it largely depends on the stage at which the cancer was detected. An early diagnosis can prove very beneficial for the patient, as with time and age cancer becomes very complex to treat and may return even after a surgery.

What causes gastrointestinal perforation?

Gastrointestinal Perforation, a.k.a., Ruptured Bowel, a.k.a., Discontinuity of the Bowel Wall, is a potentially devastating medical condition where a hole or rupture forms in the wall of the gastrointestinal tract, which includes the large and small intestines; the stomach and the esophagus. 
Symptoms include tenderness to touch and severe constant pain. Increased breathing and heart rate, acute mental confusion, fever and sepsis may also occur.


Causes of the condition:
  1. Ischemia (inadequate blood supply): This can be Bowel Obstruction or Necrosis. Bowel obstruction is where enlargement of the bowel walls lead to the reduced blood supply and Necrosis; which is the death of cells due to lack of blood supply. Both of which can lead to rupture or perforation. This is more common among the elderly, specifically, among those with clotting disorders, coronary disease and a history of smoking.
  2. Infection: 2 main causes are: Appendicitis, where the finger-shaped pouch projecting into the colon on the lower right side of the abdomen becomes inflamed; and Diverticulitis, where the small pouches that form on the side of the intestines become inflamed. It is believed that both these are due to entrapment of fecal matter, causing internal pressure and infection leading to perforation.
  3. Erosive Diseases: These are those that wear out the body structure over a period of time in many ways, like ulcerous disease or invasive tumours. An ulcer directly damages the bowel wall due to infection, overproduction of acid or lack of acid protective mechanism. Tumours can form on the entire wall of the bowel leading to perforation.
  4. Physical: This can be either external or internal trauma. External or mechanical injury can be caused by either blunt or penetrating trauma to abdomen during say, an accident or a fight. Internal are usually medical in nature, often caused by instrumentation, like during an endoscopy. 

This is a life-threatening medical emergency requiring immediate medical care, and early diagnosis and treatment lead to highly improved chances of recovery.

Medical care & Management of Appendicitis

A small-pouch shaped organ on the right side of the abdomen that is connected to the colon is called an appendix. Usually, appendicitis is caused due to the swelling of the appendix, which will be inflamed and pus-filled. A stomach infection, blockage in the lining of the appendix could lead to appendicitis. The infection or the bacteria would multiply quickly, causing inflammation and pus in the appendix. Timely treatment is a must, or else it would rupture and lead to further complications.

 Appendicitis

Appendectomy 

An appendectomy is a process of surgically removing the appendix. This is considered to be a common procedure performed under emergencies. It is considered to be an emergency as the infected appendix might rupture or burst, allowing the infectious contents to enter the abdominal cavity. This surgery can help prevent complications.

Abdominal testing, blood test, urine test, and CT or ultrasound would be used to diagnose the issue. Sometimes, doctors would prescribe certain medications that could reduce the infection and pain, but severe conditions cannot be controlled with medications; hence, appendectomy is highly recommended. 

Procedure 

Using keyhole surgery or laparoscopy, doctors would perform an appendectomy. The procedure is less invasive than open surgery and performed under general anesthesia. Tiny incisions would be made in the abdomen into which a special tool called a port would be inserted. Carbon dioxide would be pumped through this port so that the stomach would get inflated and make the organs in the abdomen easier to examine. A laparoscope would be inserted through one of the incisions, and using other tools; the doctor would identify the position and remove the appendix. Sterile fluid will be instilled to remove the remaining infectious materials. The surgical instruments would then be removed so that the carbon dioxide would escape, and then the doctor would close the incisions with sutures or bandages. 

Recovery time 

Based on the severity of the infection, the recovery period would vary for each individual who has undergone an appendectomy. If the appendix has ruptured, then the hospital stay would be longer. Specific steps, when followed, help in faster recovery such as:
  • Avoid driving 
  • Avoid alcohol 
  • Follow a healthy diet plan and drink plenty of fluids 
  • Refrain from lifting heavy objects at least for 10-14 days post-surgery
  • Wash the hands thoroughly after touching the area close to an incision site 
  • Follow the instructions given by the doctor divinely 
  • Check the bandages to make sure there are no infections
  • Avoid wearing tight clothes 
  • Take pain killers and other medications as prescribed by the surgeon
  • Advised to hold a pillow over the tummy while sneezing or coughing to minimize the strain on the incision site


If there are any issues after the surgery, it is suggested to have an immediate follow-up. Follow-up care is a must as it is the central part of the treatment and safety.

The link between obesity & stomach cancer

Obese would be titled for people whose body mass index is greater than 30. Excess fat and being overweight can be termed as obesity. This excess of body fat can be harmful and cause a lot of health issues and complications as well. 

 Obesity

The most common causes of obesity would be too much intake of food, alcohol, certain medications, lack of sleep, and no physical activity. These could cause certain types of cancer, and women are at higher risk of developing cancers of the endometrium, breast, colon, kidney, and gallbladder.

Obesity & stomach cancer

Stomach cancer is considered to be a malignant ulcer in the lining of the stomach. It is also known as gastric cancer. One of the causes that leads to stomach cancer is the excess of fat or obesity. The chronic inflammation associated with obesity increases the risk of gastric cancer. Obesity can produce more insulin and leptin, which would lead to increased cell proliferation, promoting the growth of cancerous cells. People who are obese are more prone to develop H. pylori or Helicobacter pylori infection, which is considered to be a risk factor for peptic and gastric cancer. And the abdominal fat can be a risk factor as it produces oesophageal reflux, which in turn causes gastric cancer. 

Medical care 

Obesity would become a hindrance to a lot of treatments or treatment protocols. It affects the dosage of chemotherapy. Obesity is just one factor, but it layers on top of all the other factors that would trigger stomach cancer. A healthy lifestyle and diet can be the best way to prevent cancer, plus lowering the risk of obesity and other complications. 

Gastroscopy, CT scan, and upper GI series would be used to diagnose stomach cancer. Gastric surgery can be performed to help treat obesity when other treatments and methods fail. Usually, gastric cancer would require surgery in the form of partial or total gastrectomy or bypass.

 Stomach Cancer

Even though there are various methods and treatments for gastric cancer, it is better to prevent the issue initially. It is always suggested to maintain a proper diet to stay fit and healthy.

  • Abdominal pain and cramping   
  • Fatigue
  • High Fever
  • Urgency to defecate

Types
There are five types of ulcerative colitis:
1. Ulcerative proctitis - Inflammation occurs to the rectum of the large intestine, and small amount of bleeding passing in your stool is the only sign of the disease. 
2. Proctosigmoiditis - Inflammation occurs in sigmoid colon and rectum. Signs and symptoms are abdominal cramps, bloody diarrhea, and an inability to move the bowels instead of having urge. 
3. Left-sided colitis. Inflammation starts from rectum and go up to the sigmoid and descending colon causes abdominal cramping, bloody diarrhea, and weight loss.
4. Pancolitis - Often affects the colon entirely and causes intense bloody diarrhea, fatigue and notable weight loss.
5. Acute severe ulcerative colitis - This form of colitis found rarely in patients that infect the entire colon causes profuse diarrhea, severe pain, fever, bleeding and inability to eat.

What can I expect after Gastric Sleeve Surgery?

Obesity, "the state of being grossy fat or overweight", is extremely prevalent in the developed countries of the West, especially among the young. The developing countries are not very far behind;, particularly in the sprawling metro cities. Lack of exercise and bad diet are among the many reasons attributed to its spread.

Gastric Sleeve Surgery chennai

Sometimes, among the extreme cases, surgical measures have to be adopted. It is in this scenario that Gastric Sleeve Weight Loss Surgery is advised.

What exactly Gastric Sleeve Surgery?

The simplest explanation is: it reduces the physical size of the patient's stomach. Here, surgeons surgically remove part of the stomach and stitch together the remaining portion in a tubular sleeve like a sack, and hence the name "Gastric Sleeve Surgery." It takes two to three days and is permanent.

What can one expect after the surgery?

  • After the surgery, you will be able to drink only clear fluid for 2-3 days and, then move on to mashed food products and protein mixes for a month. You will then be able to take normal diet but in very small quantity.
  • Expect to lose a lot of weight and medical conditions related to weight will improve. How much that will be will vary from person to person..
  • Avoid eating high sugar foods like soda and fruit juice.
  • Tiredness may be present for a month and will soon disappear.

What To Know About Chronic Pancreatitis?

The pancreas is the most hardworking organ in the human body. It plays a significant role in your digestion process. It makes enzymes that help your digestive process and insulin to keep your blood sugar levels under control. Any inflammation, fibrosis, or scarring of the pancreas will develop a condition called pancreatitis. 


What is pancreatitis?


Pancreatitis is a disease in which the pancreas becomes inflamed or damaged. This is when the digestive enzymes are activated before they are released into the small intestine and begin attacking the pancreas. Pancreatitis can become a chronic problem. Treatment for this condition varies depending on whether your pancreatitis is acute or chronic. 

Acute pancreatitis is a sudden inflammation of your pancreas, which can be very painful. You may have nausea, vomiting, and fever. If acute pancreatitis slowly gets worse,It may lead to chronic pancreatitis.

What is chronic pancreatitis?


Chronic pancreatitis is an irreversible and progressive disorder of the pancreas caused by an inflammation that constantly occurs over the long haul. Chronic pancreatitis can create permanent damage to the pancreas. Scar tissue develops from this long-term inflammation.

What causes chronic pancreatitis?


If you have chronic pancreatitis, the digestive enzymes that would normally travel by tubes inside your pancreas and empty into your upper intestine, become trapped inside your pancreas, this causes pain and scarring. The trapped enzymes slowly destroy your pancreas.

The most common cause of chronic pancreatitis is drinking too much alcohol over many years. 

 Other causes include:
  • An attack of acute pancreatitis that damages your pancreatic ducts
  • A blockage of the main pancreatic duct caused by cancer 
  • Certain autoimmune disorders
  • Cystic fibrosis
  • Hereditary diseases of the pancreas
  • Smoking
  • Unknown cause in some cases 

How to diagnose?


If pancreatitis is suspected, It is best diagnosed with tests that can evaluate the structure of the pancreas via radiography. Your doctor will likely use a combination of blood tests and imaging studies to make a diagnosis. 

Computed tomography is the best imaging modality for diagnosis. Your doctor may recommend a variety of diagnostic tests such as; Transabdominal ultrasound, Endoscopic ultrasound, and Magnetic resonance cholangiopancreatography (MRCP).

How is chronic pancreatitis treated?


Day-to-day treatment includes: 
  • Pain medicine
  • Pancreatic enzyme supplements with every meal
  • Insulin, if you develop diabetes
  • Vitamin supplements, if needed
For acute pancreatitis or a flare-up, you may need to stay in the hospital for treatment. Your exact treatment will depend on the cause of your chronic pancreatitis, how severe the symptoms are, and your physical condition. 

Acute treatments may include:
  • Feeding through a tube through the nose into the stomach
  • Diet
  • IV fluids
  • Pain medicines
  • Surgery 

You can control pancreatitis with a healthy lifestyle and medical treatment when necessary. Organizations such as the SIMS hospital can provide resources and support to help you live a full and healthy life with pancreatitis.

However, if any of your symptoms reappear, speak with your doctor as soon as possible.
