Dr. Dinesh M G has more than 10 Years of clinic experience. The Clinician specializes in and performs the following surgeries:
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.
Cervical cancer is an abnormal growth of cancer cells that starts in the cervix. The cervix is the narrow part of the lower uterus. It is the entrance of the uterus, often referred to as the neck of the womb. Cervical cancer is the fourth most common type of cancer in women around the world. It is the fourth leading cause of death caused by cancer in women. However, the important thing to note is that cervical cancer is also one of the most preventable types of cancer and early diagnosis of the disease can improve the mortality rate amongst patients.
A dramatic reduction in cervical cancer occurrence is primarily due to the widespread use of advanced screening tests such as pap tests to detect cervical abnormalities and allow for early treatment.
Under normal circumstances, the ectocervix is covered with flat, thin cells called squamous cells and the endocervix is made up of another kind of cells called columnar cells. The area where these cells meet is called the transformation (T) zone. The T zone is the most likely location for cervical cancer cells to develop.
A majority of cervical cancer cases occur because of a virus called human papillomavirus (HPV). HPV is a sexually transmitted virus. It can transfer through
There are many types of the HPV virus and not all types of HPV cause cervical cancer. Some of the HPV may cause genital warts. Some other cervical cancer risk factors include smoking, weak immune system, oral contraceptives, and multiple pregnancies.
More than 90 percent of the cervical cancers are squamous cell carcinoma. The second most common type of cervical cancer is adenocarcinoma. Adenosquamous carcinomas or mixed carcinomas are some of the rare types of cervical cancer.
Usually, there are no early signs of cervical cancer, but several cervical cancer symptoms may appear as the tumor grows in size. Some of the common cervical cancer symptoms include the following:
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.
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.
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:
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.
There are no early signs of colorectal cancer, but once it grows, the patients may experience the following colon cancer symptoms:
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:
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:
Lung cancer is an uncontrolled growth of cells that start off in the lungs. Usually, lung cancer starts in the cells that line the air passages. Instead of developing into healthy lung tissue, the cells divide rapidly and form tumours.
Lung cancer can grow and spread beyond the lung to reach other parts of the body through metastasis. Lung cancers can begin in any part of the lung, but 90 percent of lung cancers begin in the epithelial cells, which are the cells lining the larger and smaller airways also known as bronchi and bronchioles.
This is the reason why lung cancers are sometimes called bronchogenic cancers or bronchogenic carcinomas. Lung cancer is the most common cancer in the world, among both men and women. It is the leading cause of cancer deaths worldwide.
Long-term smoking is the main cause of lung cancer. After smoking, genetic factors and exposure to radon gas, asbestos, second-hand smoke or other forms of air pollution can also increase the risk of lung cancer.
There are two major types of lung cancers, based on the appearance of lung cancer cells under the microscope:
It is necessary to determine the stage of lung cancer by finding out how far cancer has spread, before initiating treatment of lung cancer.
The following are the four lung cancer stages of NSCLC:
After the determination of stage, treatment of lung cancer starts with choosing the best suitable option for the patient. However, there is usually no single treatment for lung cancer. So the patient often receives a combination of therapies and palliative care.
Lung cancer symptoms may vary, depending upon where and how widespread the tumour is. A person with lung cancer may have following lung cancer symptoms:
Ovarian cancer refers to the abnormal growth of cells in the ovaries, which are an important part of the female reproductive system. Ovaries are two small glands, located on either side of the uterus. They help produce female sex hormones and store or release eggs. An ovarian tumor is it is the eighth most common type of cancer among women. It is the fifth most common cause of cancer deaths in women around the world. Ovarian cancer can be life-threatening if not diagnosed and treated on time, however, the chances of survival are great in the case of early diagnosis.
Ovarian cancer forms when normal ovarian cell growth fails, and there is an uncontrolled growth of cells. Most of the ovarian cancers arise from the lining cells (epithelium) of the ovary. The ovarian tumor can metastasize and spread to other organs of the body.
There is no identified and known cause of ovarian cancer. However, there are some risk factors associated with the disease. Family history (genetics) of ovarian cancer, older age, breast cancer, obesity, and endometriosis are some of the known ovarian cancer risk factors. Other than these, menstrual cycles play a major role in ovarian cancer. The high number of total lifetime ovulations, greater the risk of ovarian cancer. That is, women who have had their periods before the age of 12 are at an increased risk of ovarian cancer.
The risk of ovarian cancer is also high in women suffering from familial melanoma, which is characterized by the presence of certain genes. These genes are inherited from parents and mostly occurs when two or more relatives suffer from the aggressive form of melanoma or skin cancer.
Typically, the symptoms of ovarian cancer are subtle during the early stage. However, the patients may experience signs of ovarian cancer once the cancer advances and starts to grow. The following are some of the ovarian cancer symptoms:
Pain in the pelvis or belly
Bloating
Frequent and urgent urination
Changes in bowel habits
Nausea and fatigue
Weight loss
Breathlessness
Loss of appetite
These signs of ovarian cancer can be confused with those of ovarian cyst. However, patients must know that ovarian cysts are far more common and primarily affects women during their childbearing age.
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, 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.
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 other types of stomach cancers include squamous and small cell carcinoma and leiomyosarcoma. These cancers are very rare.
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:
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:
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:
