Pancreatic Cancer

#pancreatic cancer, #chemotherapy, #abdominal CT, #jaundice, #chronic pancreatitis

Pancreatic cancer is cancer that develops in the pancreas, an organ located deep within the body. Because it produces few early symptoms, it is often found at a later stage. Please do not attempt to self-diagnose using an online encyclopedia; if you notice any concerning symptoms, be sure to see a gastroenterology or hepatobiliary-pancreatic surgery specialist.

Peripheral Vascular Disease (Leg Vascular Disorders)

#peripheral arterial disease, #deep vein thrombosis, #varicose veins, #atherosclerosis, #edema, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet

Peripheral vascular disease is a condition in which the blood vessels in the legs, far from the heart, become narrowed or blocked by blood clots (thrombi), and it can be a medical emergency. In serious cases, tissue in the leg can die and amputation may be necessary, so if your leg is severely swollen and painful, please consult a cardiology or vascular specialist immediately.

Reflux esophagitis is a condition in which stomach contents flow back up into the esophagus and cause inflammation of the esophagus. Heartburn and acid regurgitation (a sour fluid rising into the throat) are typical symptoms, and the condition can be managed with lifestyle changes and drug treatment. If symptoms persist, please consult a medical specialist.

Retinal Artery Occlusion

#retinal artery occlusion, #retina, #decreased vision, #eye stroke, #central retinal artery occlusion, #high blood pressure, #diabetes, #blurry vision, #difficulty seeing, #hazy vision

Retinal artery occlusion is a condition in which the artery that supplies blood to the retina is suddenly blocked. Like a stroke, in which a blood vessel in the brain is blocked, it damages the nerve cells involved in vision, and it is sometimes called an 'eye stroke.' If sudden vision loss occurs, seek immediate medical attention at an emergency room or ophthalmology department.

Rheumatoid arthritis is an autoimmune disease in which the immune system attacks the body's own joints and causes inflammation. Joint stiffness, swelling, and pain usually appear symmetrically on both sides, mainly in the small joints of the hands and feet. Early diagnosis and treatment can help reduce the impact on daily life. If you suspect symptoms, please consult a medical specialist.

Robotic Hepatobiliary and Pancreatic Surgery

#robotic surgery, #laparoscopic surgery, #hepatobiliary and pancreatic surgery, #liver donation, #minimally invasive surgery, #living donor liver transplantation, #surgical scar, #open surgery, #lack of energy, #lethargy, #persistent fatigue

Robotic surgery is a method in which the surgeon sits at a console (control device) and operates by controlling robotic arms. Using 10x magnified three-dimensional (3D) images and freely moving robotic arms, it can allow more precise manipulation than laparoscopic surgery. It is also used for liver, bile duct, and pancreatic surgery, and for liver donation surgery. Whether robotic surgery is suitable, and which method is used, depends on each patient's condition, so please consult a medical specialist.

Robotic Surgery for Colon and Rectal Cancer

#colorectal cancer, #rectal cancer, #robotic surgery, #minimally invasive surgery, #general surgery

Robotic surgery can offer several advantages when operating on cancers of the colon and rectum. However, robotic surgery is not the right choice for every patient. Do not rely on information from the internet to choose a surgical method; choose it based on an accurate diagnosis by a surgical specialist.

Robotic Surgery for Liver Cancer and Liver Transplantation

#liver cancer, #liver transplantation, #robotic surgery, #general surgery, #liver cirrhosis

Robotic surgery is a method in which the surgeon controls a robot and operates through a few small openings in the abdomen. A more expensive operation is not always the better choice. Do not decide based on this encyclopedia alone; please consult a surgical specialist to find the safest surgical method for the patient.

Secondhand Smoke (Passive Smoking)

#secondhand smoke, #passive smoking, #smoking cessation, #heart disease, #stroke, #lung cancer, #diabetes mellitus, #respiratory system, #headache, #a splitting headache, #migraine, #back-of-head pain, #dry cough, #persistent cough, #cough that won't stop, #blood-streaked sputum, #coughing up blood, #weakness in arms and legs, #difficulty moving one side of the body

Secondhand smoke exposure, also called passive smoking, means that a person who does not smoke breathes in smoke from a smoker's cigarette. Tobacco smoke contains thousands of chemicals, including carcinogens (substances that can cause cancer), and long exposure in an enclosed space can be harmful even to nonsmokers. If you are concerned about secondhand smoke, please consult a medical specialist.

Both regular cigarettes and e-cigarettes are harmful to health. Smoking raises the risk of many conditions, including lung cancer and other cancers, cardiovascular disease, and chronic obstructive pulmonary disease (COPD). Quitting smoking is not easy, but getting help from a medical specialist makes success more likely. If you've decided to quit, please work with a healthcare team rather than trying on your own.

Soft Tissue Sarcoma

#soft tissue sarcoma, #sarcoma, #extremity sarcoma, #soft tissue tumor, #soft tissue neoplasm, #rare cancer, #malignant tumor, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet

Soft tissue sarcoma is a malignant tumor (cancer) that arises in the soft tissues of the body, such as muscle, fat, blood vessels, nerves, and connective tissue. It is a very rare cancer, and early detection and treatment are important. If you have a lump on your body that keeps growing over several months, please consult a medical specialist.

Stroke

#stroke, #dementia, #vascular dementia, #high blood pressure, #snoring, #weakness in the arms or legs, #difficulty moving one side of the body

Stroke is a medical emergency that occurs when a blood vessel in the brain becomes blocked or ruptures. A blocked blood vessel is called a cerebral infarction, and a ruptured one is called a cerebral hemorrhage. If symptoms appear, going to the emergency room immediately is the most important way to reduce aftereffects. Stroke is also closely related to dementia. The main symptom of stroke is the loss of a specific bodily function, such as paralysis of the arms or legs. The most important factor in treatment is the golden time (the critical time window for treatment), so please be sure to consult a medical specialist for an accurate diagnosis. If abnormal symptoms appear, call 119 (Korea's emergency number) or go to the emergency room immediately.

Structure and Function of the Kidneys

#kidney, #renal, #glomerulus, #renal tubule, #erythropoietin, #renin, #water balance regulation, #salt balance regulation, #body swelling, #facial swelling, #leg swelling, #swelling of the hands and feet

The kidneys are vital organs that filter the blood and remove waste products through urine. Beyond waste removal, the kidneys perform a range of functions, including regulating water and salt balance, controlling blood pressure, and stimulating red blood cell production. Understanding the structure and function of the kidneys can help you protect your kidney health. If a problem with kidney function is suspected, please be sure to consult a medical specialist.
