Procedures
Abdominoperineal Resection

Abdominoperineal resection (APR) is a type of a surgery in which the anus, rectum, and sigmoid colon are removed through small cuts in the belly. It is a surgical procedure done primarily to remove the cancer of the rectum. Typically, abdominoperineal resection (AP) is conducted as an elective procedure. This procedure is most often used to treat rectum cancer if it is located very low in the rectum or in the anus, close to the sphincter muscles.

Nowadays, advanced surgical techniques and other treatment modalities have brought an increase in the rate of sphincter-sparing operations. However, APR surgery is still necessary in selected cases, especially if the patient has distal tumors or poor sphincter function.  AP resection is a major operation. During perineal resection, the rectum, distal colon, and anal sphincter complex are completely removed using both anterior abdominal and perineal incisions. Once the anus and rectum are removed, a permanent colostomy is needed to complete the procedure.

Colostomy brings the colon to an opening at the surface of the skin, which allows the waste to pass out of the body. This new opening is called stoma and usually measures from one to one-and-a-half inches in diameter. A pouch, or a stoma appliance, is needed to be worn at all times. The stoma has no sphincter muscles, so there is no conscious control over the elimination of waste products from the body after the procedure.

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
Hemicolectomy

The last part of the gastrointestinal system is referred as the colon and it is 5-6 cm long. It is ‘U’ shaped and it starts from the distal part of the small intestine and is connected to the rectum and anus. It absorbs the fluids, processes the metabolic waste products, and eliminates through the rectum and anus. The removal of the colon is called colectomy.

There are different types of colectomies such as complete colectomy,  right hemicolectomy, left hemicolectomy, sigmoid colectomy, and proctocolectomy. The surgical removal of the left side of the colon (descending colon) is called left hemicolectomy surgery. The surgical removal of the cecum, ascending colon, and the hepatic flexure (right side of the colon) is called as the right hemicolectomy surgery.

Some of the conditions that require complete colectomy or hemicolectomy surgery include the following:

  • Colon cancer
  • Crohn’s disease
  • Blockage of the colon
  • Precancerous polyps
  • Hereditary polyps
  • Benign tumours
  • Irritable bowel syndrome (IBS)
  • Gastrointestinal bleeding
  • Bowel twisting and obstruction
  • Ulcerative colitis
  • Appendicitis with inflammation of the cecum
  • Right-side colonic diverticular disease (diverticulosis)

A hemicolectomy procedure can be performed as a laparoscopic or open surgery. The type of the surgery to be performed is decided by the surgeon during the evaluation and the decision depends on the age and the condition of the patient.

Sometimes the laparoscopic procedure can also be turned into open surgery, depending on the feasibility of the procedure with respect to safety and accuracy. Overall, the following parameters decide whether a laparoscopic or an open surgical procedure will be performed:

  • Age
  • Diagnosis
  • Medical history
  • Personal preference
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
Pancreatic Cancer Treatment

Pancreatic cancer starts from the cells and tissues of the pancreas – a crucial organ that releases enzymes for digestion. It is also responsible for the production of insulin, the crucial hormone that regulates blood sugar in humans.

The pancreas can be affected by both non-cancerous as well as cancerous tumors. The most common type of pancreatic cancer is pancreatic ductal adenocarcinoma, which starts in the cells that line the ducts responsible for the transport of enzymes from the pancreas to the outside.

Pancreatic cancer is often diagnosed at an advanced stage – when it has spread to other nearby organs and therefore, the treatment is challenging in such situations. The diagnosis mostly takes place when certain symptoms are observed.

Stomach Cancer Treatment

Stomach cancer, also known as gastric cancer, is the fifth most common cancer worldwide. This disease is a result of the growth of cancerous and malignant cells in the inner lining of the stomach.

Stomach cancer does not grow overnight as this disease usually grows slowly over many years. Some pre-cancerous changes take place before true cancer actually develops. But these early changes rarely result in any symptoms and therefore, often go undetected in the early stage when it is most easy to treat it.

Gastric cancer can grow through the wall of the stomach and invade nearby organs. It can easily spread to the lymph vessels and lymph nodes. In an advanced stage, it can travel through the bloodstream and spread or metastasize to organs such as the liver, lungs, and bones. Usually, people diagnosed with stomach cancer have either experienced metastasis already or eventually develop it.

Types of Stomach Cancer

Stomach cancer should not be confused with other cancers in the abdomen or esophageal cancer. Some other cancer can also occur in the abdomen, including cancer of the large and small intestine, liver or pancreas. These cancers may have different symptoms, outlook, and options for treatment.

Some of the common types of gastric cancer include:

  • Adenocarcinoma: It is the most common form of stomach cancer and about 90 to 95 percent of stomach cancers are This form of cancer develops from the cells that form the innermost lining (mucosa) of the stomach.
  • Lymphoma: This is a rare form of stomach cancer and only about four percent of stomach cancers are lymphomas. These are cancers of the immune system tissue, sometimes found in the wall of the stomach.
  • Gastrointestinal stromal tumor (GIST): It is a rare kind of tumor that starts in very early forms of cells in the wall of the stomach calledinterstitial cells of Cajal. GISTs can be found anywhere in the digestive tract.
  • Carcinoid tumour: It is also a rare form of stomach cancer and about three percent of stomach cancers are carcinoid tumors. Carcinoid tumors start in cells of the stomach that produced hormones.

Some other types of stomach cancers include squamous and small cell carcinoma and leiomyosarcoma. These cancers are very rare.

Stomach Cancer Causes

There is no single, definite cause behind stomach cancer. However, several stomach cancer risk factors have been identified that could potentially lead to the formation to a tumor in the stomach. Some of these stomach cancer causes or risk factors include:

  • Inflammation of the gut called gastritis
  • Infection with common bacteria called Helicobacter pylori
  • Long-lasting anaemia
  • Growth in stomach called polyps
  • Smoking
  • Obesity
  • Excessive consumption of smoked, pickled or salty foods
  • A-type blood group
  • Epstein-Barr virus infection
  • Certain genes (family history of disease)

Stomach Cancer Symptoms

There can be several early stomach cancer symptoms. However, the signs of stomach cancer could be present because of some other underlying condition as well. Unfortunately, this is the main reason why it is difficult to make stomach cancer diagnosis at an early stage.

Some of the early stomach cancer symptoms may include:

  • Heartburn
  • Regular indigestion
  • Slight nausea
  • Loss of appetite
  • Frequent burping
  • Feeling bloated

But just experiencing indigestion or heartburn after a meal does not really mean that you have cancer. Although, if you experience these symptoms a lot, talk to your doctor, who can decide whether to conduct further tests or not.

As advanced gastric cancer grow, you may experience more serious signs of stomach cancer, including the following:

  • Frequent stomach ache or pain in the sternum
  • Frequent heartburns
  • Vomiting containing blood
  • Dysphagia (swallowing difficulties)
  • Loss of appetite, accompanied by sudden weight loss
  • Blood in stools
  • Excessive fatigue
  • Yellowish eyes or skin
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
