Pancreatectomy Health Dictionary

Inflammation of the pancreas, which may be acute or chronic. The main causes of acute pancreatitis are alcohol abuse and gallstones. Less common causes are injury, viral infections, surgery on the biliary system, or certain drugs. Chronic pancreatitis is usually due to alcohol abuse. Rarer causes include hyperlipidaemias, haemochromatosis, and severe acute pancreatitis. Chronic pancreatitis leads to permanent damage. Acute pancreatitis is less damaging but there may be recurrences.Symptoms of acute pancreatitis are a sudden attack of severe upper abdominal pain, which may spread to the back, often with nausea and vomiting. Movement often makes the pain worse. The attack usually lasts about 48 hours. Chronic pancreatitis usually has the same symptoms, although the pain may last from a few hours to several days, and attacks become more frequent. If there is no pain, the principal signs may be malabsorption or diabetes mellitus.

Severe acute pancreatitis may lead to hypotension, heart failure, kidney failure, respiratory failure, cysts, and ascites. Chronic pancreatitis may also lead to the development of ascites and cysts, as well as bile duct obstruction and diabetes mellitus.

A diagnosis may be made by blood tests, abdominal X-rays, ultrasound scanning, CT scanning, MRI, or ERCP. Acute pancreatitis is treated with intravenous infusion of fluids and salts and opioid analgesic drugs. In some cases, the gut may be washed out with sterile fluid, or a pancreatectomy may be performed and any gallstones that are present removed. Treatment for the chronic form is with painkillers, insulin, pancreatin, and, in some cases, pancreatectomy.... pancreatitis

whipworm infestation Small, cylindrical whip-like worms, 2.5–5 cm long, that live in the human large intestine. Infestation occurs worldwide but is most common in the tropics. Light infestation causes no symptoms; heavy infestation can cause abdominal pain, diarrhoea, and, sometimes, anaemia, since a small amount of the host’s blood is consumed every day.

Diagnosis is through the identification of whipworm eggs in the faeces. Treatment is with anthelmintic drugs, such as mebendazole. A heavy infestation may require more than 1 course of treatment. whitehead A very common type of skin blemish (see milia).... whipple’s operation

A cancerous tumour of the exocrine tissue of the pancreas. The cause is unknown, but smoking and a high intake of fats or alcohol may be contributing factors. Symptoms include upper abdominal pain, loss of appetite, weight loss, and jaundice. There may also be indigestion, nausea, vomiting, diarrhoea, and tiredness. In many cases, symptoms do not appear until the cancer has spread to other parts of the body.

Diagnosis usually requires ultrasound scanning, CT scanning or MRI of the upper abdomen, or ERCP.

In early stages, pancreatectomy, radiotherapy and anticancer drugs may provide a cure.

In later stages, little can be done apart from provision of palliative treatment.... pancreas, cancer of
