Procedures
Appendectomy

Appendectomy is a surgical procedure in which the inflamed appendix causing abdominal pain is removed. An appendix is a pouch-like structure attached to the large intestine and is located on the lower right side of the abdomen.

An appendectomy can be done laparoscopically as well as an open procedure. Complications may arise if an appendix has burst due to inflammation, which may increase the recovery time as a drain is put in the incision for a few days after the surgery.

Colorectal Cancer ( Colon Cancer ) Treatment
  • Overconsumption of animal protein, saturated fats, and calories
  • Low dietary fibre intake
  • Overconsumption of alcohol
  • Excessive smoking
  • Family history of colorectal cancer
  • Obesity
  • Physical inactivity

Colorectal cancer is the second most common cancer in the world. It can metastasize and spread to other body parts. Colorectal cancer is dangerous and can be life-threatening. But death rate from colorectal cancer has dropped in the recent years, thanks to advance screening techniques and better colorectal treatment options.

What is colon cancer?

Colorectal cancer is also known as bowel cancer, colon cancer, or rectal cancer. Colorectal cancer begins as an abnormal growth of cells in the inner lining of the colon or rectum. This abnormal growth is called a polyp.

Some types of polyps can change into cancer over the course of several years. But it does not mean that all polyps have the tendency to become cancerous. The chance of changing a polyp into colorectal cancer depends on the type of polyp that grows. 

Colorectal cancer can affect men and women equally. However, studies have proven that men might develop it at a younger age.

What causes colon cancer?

There is no definite cause of colorectal cancer, but old age and certain lifestyle factors can increase colorectal cancer risk. Some of these colorectal cancer risk factors include the following:

Types of Colorectal Cancer

A majority of colorectal cancers are adenocarcinoma. If you have been diagnosed with colorectal cancer, there are 95 percent chances that it is an adenocarcinoma. But there are some other types of colorectal cancer such as carcinoid, gastrointestinal stromal, lymphomas, and sarcomas.

Colorectal Cancer Symptoms

There are no early signs of colorectal cancer, but once it grows, the patients may experience the following colon cancer symptoms:

  • Fatigue, weakness, and shortness of breath
  • Change in bowel habits, including diarrhoea or constipation
  • Blood in stool
  • Abdominal discomforts such as cramps, bolting or pain
  • Dramatic weight loss
Laparoscopic Gall Bladder Removal

Laparoscopic gallbladder removal is a minimally invasive surgery in which small incisions and specialized tools are used to remove a diseased or inflamed gallbladder. The gallbladder is a small organ located in the right upper abdomen below the liver. It helps in the storage of bile which is used to breakdown food during digestion. Laparoscopic gallbladder removal is a minimally invasive surgery in which small incisions and specialized tools are used to remove a diseased or inflamed gallbladder. The main reason for having a gallbladder removed is the presence of gallstones and the complications it might cause. Other reason for the surgery might include biliary dyskinesia, cholecystitis, pancreatitis. It is called as laparoscopic cholecystectomy and it carries only a small risk of complications.

Laparoscopic Hernia Repair
Whipple's Procedure

Among all the forms of common cancers, it has been found that pancreatic cancer has the poorest prognoses. This reason can be attributed to the cancer growing and spreading long before it starts showing any visible symptoms. A survey revealed that only 6 percent patients survive for more than five years after its diagnosis. For some patients, a very complicated surgery known as the Whipple's procedure will be able to extend life and can be counted as a potential cure. After undergoing Whipple's surgery the five-year rate of survival can be increased to 25 percent.

People who are suffering from pancreatic cancer are eligible for the Whipple’s operation. People who have tumors confined to the pancreatic head and the blood vessels, lungs, and livers or the abdominal cavities are still not affected and are recommended to undergo this procedure after intensive testing and evaluation.

People with benign tumors are also recommended to undergo the procedure. For patients who are suffering metastasis, this procedure is not recommended. Cancer in the ampulla, region where the pancreatic duct and bile duct enter, can also be treated.

Whipple's Operation

Whipple's operation is conducted in the head of the pancreas. During the surgery, a segment of the duodenum, bile duct, and the gallbladder is removed. In some cases, a portion of the stomach may also be removed. After these segments are removed, the remaining pancreas, bile duct, and even portion of the intestine will be sutured back to the main intestine to direct the secretion of the gastrointestinal segment into the gut. The Whipple& procedure for pancreatic cancer is long and has several complications associated with it.

A doctor may recommend you to undergo Whipple operation for the treatment of the following conditions:

  • Pancreatic cysts, tumors, and cancer
  • Ampullary cancer
  • Pancreatitis
  • Neuroendocrine tumors
  • Cancer of the bile duct
  • Small bowel cancer
  • Traumatic injury to the small intestine or the pancreas
  • Tumor of disorders of the bile ducts, pancreas, or duodenum
