Whereas it is true that no operation has been profoundly affected by the advent of laparoscopy than cholecystectomy has, it is equally true that no procedure has been more instrumental in ushering in the laparoscopic age than laparoscopic cholecystectomy has. Laparoscopic cholecystectomy has rapidly become the procedure of choice for routine gallbladder removal and is currently the most commonly performed major abdominal procedure in Western countries.[1] A National Institutes of Health consensus statement in 1992 stated that laparoscopic cholecystectomy provides a safe and effective treatment for most patients with symptomatic gallstones and has become the treatment of choice for many patients.[2] This procedure has more or less ended attempts at noninvasive management of gallstones. The initial driving force behind the rapid development of laparoscopic cholecystectomy was patient demand. Prospective randomized trials were late and largely irrelevant because advantages were clear. Hence, laparoscopic cholecystectomy was introduced and gained acceptance not through organized and carefully conceived clinical trials but through acclamation. Laparoscopic cholecystectomy decreases postoperative pain, decreases the need for postoperative analgesia, shortens the hospital stay from 1 week to less than 24 hours, and returns the patient to full activity within 1 week (compared with 1 month after open cholecystectomy).[3, 4] Laparoscopic cholecystectomy also provides improved cosmesis and improved patient satisfaction as compared with open cholecystectomy. Although direct operating room and recovery room costs are higher for laparoscopic cholecystectomy, the shortened length of hospital stay leads to a net savings. More rapid return to normal activity may lead to indirect cost savings.[5] Not all such studies have demonstrated a cost savings, however. In fact, with the higher rate of cholecystectomy in the laparoscopic era, the costs in the United States of treating gallstone disease may actually have increased. Trials have shown that laparoscopic cholecystectomy patients in outpatient settings and those in inpatient settings recover equally well, indicating that a greater proportion of patients should be offered the outpatient modality
Ventricular fibrillation is a heart rhythm problem that occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly, instead of pumping blood. Sometimes triggered by a heart attack, ventricular fibrillation causes your blood pressure to plummet, cutting off blood supply to your vital organs. Ventricular fibrillation, an emergency that requires immediate medical attention, causes the person to collapse within seconds. It's the most frequent cause of sudden cardiac death. Emergency treatment includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called a defibrillator. Treatments for those at risk of ventricular fibrillation include medications and implantable devices that can restore a normal heart rhythm.
Your stomach must be empty, so you should not eat or drink anything for approximately 8 hours before the examination. Your physician will be more specific about the time to begin fasting depending on the time of day that your test is scheduled. Your current medications may need to be adjusted or avoided. Most medications can be continued as usual. Medication use such as aspirin, Vitamin E, non-steroidal anti-inflammatories, blood thinners and insulin should be discussed with your physician prior to the examination as well as any other medication you might be taking. It is therefore best to inform your physician of any allergies to medications, iodine, or shellfish. It is essential that you alert your physician if you require antibiotics prior to undergoing dental procedures, since you may also require antibiotics prior to ERCP. Also, if you have any major diseases, such as heart or lung disease that may require special attention during the procedure, discuss this with your physician. To make the examination comfortable, you will be sedated during the procedure, and, therefore, you will need someone to drive you home afterward. Sedatives will affect your judgment and reflexes for the rest of the day, so you should not drive or operate machinery until the next day.
A central venous catheter, also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more. A catheter is often inserted in the arm or chest through the skin into a large vein.
Schizophreniform disorder is a mental disorder diagnosed when symptoms of schizophrenia are present for a significant portion of the time within a one-month period, but signs of disruption are not present for the full six months required for the diagnosis of schizophrenia.
The difference between bronchitis and pneumonia is that bronchitis causes an inflammation of the air passages while pneumonia causes fluid in the lungs due to an infection. The common cold however, allows people to remain active and presents itself with a clear runny nose, cough, and a low-grade or no fever.
The pain is frequently severe and is described as throbbing or pulsating. Nausea is common, and many migraine patients have a watering eye, a running nose, or congestion. If these symptoms are prominent, they may lead to a misdiagnosis of sinus headaches.
An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky.
Two types of clinically distinct necrotizing fasciitis have been described. The most common form (type II) usually occurs in individuals with no concurrent medical illness. Many patients report a history of laceration, blunt trauma, or a surgical procedure as a predisposing factor. It is typically caused by group A Streptococcus (Streptococcus pyogenes). In contrast, type I is usually seen in patients with underlying diabetes and peripheral vascular disease. It is generally a polymicrobial infection; some commonly isolated organisms include Staphylococcus aureus, Bacteroides tragi/is, Escherichia coli, group A Streptococcus, and Pre vote/fa species. Crepitus is more common if anaerobic organisms, such as Clostridium perfringens or 8 tragi/is, are involved.
Polycythemia vera (pol-e-sigh-THEE-me-uh VEER-uh) is a slow-growing type of blood cancer in which your bone marrow makes too many red blood cells. Polycythemia vera may also result in production of too many of the other types of blood cells — white blood cells and platelets. These excess cells thicken your blood and cause complications, such as such as a risk of blood clots or bleeding. Polycythemia vera isn't common. It usually develops slowly, and you may have it for years without noticing signs or symptoms. Often, polycythemia vera is found during a blood test done for some other reason. Without treatment, polycythemia vera can be life-threatening. However, with proper medical care, many people experience few problems related to this disease. Over time, there's a risk of progressing to more-serious blood cancers, such as myelofibrosis or acute leukemia.
Pleurisy is a condition in which the pleura — a membrane consisting of a layer of tissue that lines the inner side of the chest cavity and a layer of tissue that surrounds the lungs — becomes inflamed. Also called pleuritis, pleurisy causes sharp chest pain (pleuritic pain) that worsens during breathing. A variety of underlying conditions can cause pleurisy. Treatment of pleurisy involves pain control and treating the underlying condition.
Keep tabs on your blood pressure. If it's too high, your risk of a heart attack and heart disease goes up. Stress management, a healthy diet, and regular exercise can help you manage your blood pressure. Your doctor may also prescribe medications to lower your levels.
Loa loa filariasis (also known as loiasis, loaiasis, Calabar swellings, Fugitive swelling, Tropical swelling and African eyeworm) is a skin and eye disease caused by the nematode worm, loa loa. Humans contract this disease through the bite of a Deer fly or Mango fly (Chrysops spp), the vectors for Loa loa. The adult Loa loa filarial worm migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily observed. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose.The disease can cause red itchy swellings below the skin called "Calabar swellings". The disease is treated with the drug diethylcarbamazine (DEC), and when appropriate, surgical methods may be employed to remove adult worms from the conjunctiva.
