Biliary Metal Stent Placement
Biliary Metal Stent Placement samer kareem 3,747 Views • 2 years ago

The placement of a percutaneous expandable biliary endoprosthesis was first reported in 1985 by Carrasco et al. in a canine model,[1] and the endoscopic placement of expandable metal stents to relieve biliary strictures in patients was first described in 1989.[2,3] Over the past two decades, the endoscopic approach to biliary endoprosthesis placement has largely supplanted the percutaneous approach. Self-expanding metal stents (SEMS) have traditionally been used for palliation of obstructive jaundice in patients with unresectable pancreaticobiliary tumors. However, SEMS are increasingly being used in patients with resectable cancers[4] and benign biliary strictures.[5] Uncovered SEMS (uSEMS) have been shown to have longer patency periods than plastic stents when used for malignant biliary obstruction and to be cost effective if the patient's life expectancy is greater than 4–6 months.[6–8] The common causes of malignant biliary obstruction are pancreatic cancer and cholangiocarcinoma.[9–11] Biliary drainage prior to surgical resection is controversial; several investigators have reported it to be beneficial owing to the improved tissue healing with reduced bilirubin levels,[12,13] but others have also reported its deleterious effects secondary to the additional intervention..

Endometrial Cancer
Endometrial Cancer samer kareem 7,961 Views • 2 years ago

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs. Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer. Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often cures endometrial cancer.

Wound Healing

Wound healing is the process by which skin or other body tissue repairs itself after trauma. ... This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth (proliferation) and tissue remodeling (maturation).

Causes Of Ascites
Causes Of Ascites samer kareem 2,980 Views • 2 years ago

The accumulation of ascitic fluid represents a state of total-body sodium and water excess, but the event that initiates the unbalance is unclear. Although many pathogenic processes have been implicated in the development of abdominal ascites, about 75% likely occur as a result of portal hypertension in the setting of liver cirrhosis, with the remainder due to infective, inflammatory, and infiltrative conditions. Three theories of ascites formation have been proposed: underfilling, overflow, and peripheral arterial vasodilation. The underfilling theory suggests that the primary abnormality is inappropriate sequestration of fluid within the splanchnic vascular bed due to portal hypertension and a consequent decrease in effective circulating blood volume. This activates the plasma renin, aldosterone, and sympathetic nervous system, resulting in renal sodium and water retention. The overflow theory suggests that the primary abnormality is inappropriate renal retention of sodium and water in the absence of volume depletion. This theory was developed in accordance with the observation that patients with cirrhosis have intravascular hypervolemia rather than hypovolemia. The most recent theory, the peripheral arterial vasodilation hypothesis, includes components of both of the other theories. It suggests that portal hypertension leads to vasodilation, which causes decreased effective arterial blood volume. As the natural history of the disease progresses, neurohumoral excitation increases, more renal sodium is retained, and plasma volume expands. This leads to overflow of fluid into the peritoneal cavity. The vasodilation theory proposes that underfilling is operative early and overflow is operative late in the natural history of cirrhosis. Although the sequence of events that occurs between the development of portal hypertension and renal sodium retention is not entirely clear, portal hypertension apparently leads to an increase in nitric oxide levels. Nitric oxide mediates splanchnic and peripheral vasodilation. Hepatic artery nitric oxide synthase activity is greater in patients with ascites than in those without ascites. Regardless of the initiating event, a number of factors contribute to the accumulation of fluid in the abdominal cavity. Elevated levels of epinephrine and norepinephrine are well-documented factors. Hypoalbuminemia and reduced plasma oncotic pressure favor the extravasation of fluid from the plasma to the peritoneal fluid, and, thus, ascites is infrequent in patients with cirrhosis unless both portal hypertension and hypoalbuminemia are present.

Heart Attacks
Heart Attacks samer kareem 5,635 Views • 2 years ago

A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medications, stents, and bypass surgery.
