Actos Bladder Cancer Legal Scoop
Actos Bladder Cancer : Hernia: After surgery, there is an increased risk of developing an incisional hernia (a hernia through the original incision) or an inguinal hernia (a hernia in the groin). A hernia represents a weakening of the thick outer layer of tissue which holds the abdominal contents in place. With a hernia, there is an abnormal protrusion of peritoneal sac and possibly bowel. Herniation of bowel may lead to a lack of blood flow to the herniated intestine which can be serious if left untreated. Surgical correction of the hernia is usually recommended to avoid this possibility and to eliminate discomfort.
Prolonged ileus: For some individuals return of bowel function may be delayed by several days or longer. Your urologist will be following you carefully to make sure a bowel obstruction or bowel leak is not present. Ileus may require leaving the nasogastric tube in to suction off excessive fluid. In addition, hyperalimentation (complete nutrition delivered intravenously) may be initiated if the ileus is prolonged.
Urine leak: The ureters are sewn to the ileal loop in a watertight fashion. In addition, small tubes, called stents, are placed through the ileal loop, through the anastomosis of the ureter to the loop, up the ureter into each kidney. These tubes are placed to allow the ureteral-ileal anastomosis to heal and to prevent leakage. They are generally removed weeks after surgery. Besides these stents, a drain or drains are placed to siphon off any urine which may still leak from the anastomosis. Prolonged urine leakage into the abdomen will generally result in ileus and possibly secondary infection. Persistent urine leak may result from the lack of good blood supply to the ends of the ureters. Leakage is also increased in those who have had pelvic radiation in the past for other malignancies. Prolonged leakage may require repeat surgery.

Wound infection: The rate of wound infection is low. Rates are increased in diabetics, obese individuals, prolonged surgery, and in those individuals whose body temperature drops excessively during surgery. Excellent surgical technique and the use of antibiotics can lower the rate. Wound infections generally will require opening the area to allow drainage. Wound infection can result in weakening of the abdominal closure, which can cause a hernia or more rarely an evisceration (a disruption of the abdominal closure), requiring immediate surgical closure.
Cardiovascular complications: Major surgery can result in significant physical stress to the body and its physiology. Cardiac arrhythmias (abnormal heart beats) may occur and warrant medical therapy to correct. If serious, a cardiologist may be consulted. Life threatening arrhythmias may require cardioversion to correct or even the possibility of a pacemaker. A heart attack (a vascular blockage to the heart) or a cerebrovascular accident also referred to as a stroke, are fortunately rare, but sometimes devastating complications which can prove to be fatal. It is essential an individual facing major surgery with cardiac or vascular disease be properly screened prior to surgery to rule out and correct any serious underlying abnormalities. One should not face surgery with an unstable major underlying condition without correction or improvement when this can be reasonably achieved.
Pulmonary problems: After surgery, it is essential to do deep breathing exercises usually with a device called a spirometer. Bed rest, pain from surgery, and the sedative effects of pain medication can all lead to inadequate aeration of the lungs, which can lead to atelectasis (a collapsed area of the lung). Left untreated, atelectasis can lead to infection (pneumonitis or pneumonia), a potentially serious complication. For those with preceding lung disease, a respiratory therapist will likely be requested to work with the patient to clear lung secretions and increase aeration to prevent infection.

Another potential serious pulmonary problem is called pulmonary embolus. A pulmonary embolus causes damage to the lung by a blood clot which forms in another area of the body, travels through the veins of the body and ends in the lungs. Blood clots can form in the pelvic veins as a result of surgery. They can also form in the lower extremities because of prolonged bed rest and immobility after surgery. Compression stockings used during and after surgery until mobility resumes help to prevent clots in the legs. Getting the individual out of bed and ambulating as soon as possible after surgery are important to prevent clots from forming. In addition, subcutaneous heparin (a medication that stops clotting) can be given during the post-operative period to lessen the possibility of pulmonary embolus without a substantial increase in post-operative bleeding. The symptoms of a pulmonary embolus are shortness of breath and pain in the chest with breathing.
Clinical signs include a rapid heart beat and poor oxygenation of the blood. Diagnosis is confirmed with a ventilation-perfusion scan. This study will demonstrate a lack of blood flow in various parts of the lung which have good air flow (a finding consistent with a vascular blockage by a clot). In many institutions, a CT angiogram of the lungs has become the preferred study because of the speed of the study and its enhanced accuracy. An individual must not be allergic to IV contrast, nor have significant renal insufficiency if this test is to be ordered. Pulmonary emboli are usually treated with supportive measures such as supplemental oxygen and anti-coagulation of the blood to prevent further clots from forming and migrating. If a large clot has formed and continues to embolize to the lung, a small filter device may be placed in the main vein of the abdomen (the inferior vena cava) to prevent further clots from traveling to the lungs.
