Laparoendoscopic Approaches for Oncological Surgery

By

Laparoendoscopic surgery (also known as minimally invasive surgery) is a technique used in the field of oncology that allows for the removal of tumors and cancerous tissues through small incisions made in the body. This technique has several advantages over traditional open surgery, including reduced blood loss, faster recovery times, and fewer complications. In this article, we will discuss some of the techniques used in laparoendoscopic surgery for oncology.

  1. Trocar Placement: The first step in laparoendoscopic surgery is the placement of trocars. Trocars are hollow tubes that allow for the insertion of surgical instruments and a camera into the body. The number and location of the trocars used in the procedure will depend on the location and size of the tumor. The surgeon will make a small incision in the skin and insert the trocars through the incision. The camera is then inserted through one of the trocars, and the surgical instruments are inserted through the other trocars.
  2. Pneumoperitoneum: After the trocars are placed, the surgeon will create a pneumoperitoneum, which is a space filled with gas (usually carbon dioxide) in the abdominal cavity. This space allows the surgeon to see the organs and tissues more clearly and provides more room to work. The surgeon will use a special device to inflate the abdomen with gas.
  3. Dissection and Tumor Removal: Once the pneumoperitoneum is created, the surgeon will begin the dissection process. This involves using surgical instruments to cut through tissues and remove the tumor. The surgeon will use a combination of laparoscopic instruments and energy sources (such as electrocautery or ultrasonic energy) to cut through the tissues. The camera provides a clear view of the surgical field, allowing the surgeon to be precise in their movements.
  4. Hemostasis: During the dissection process, the surgeon will need to control bleeding. This is done using various techniques such as clips, electrocautery, or sutures. The surgeon will carefully monitor the surgical field to ensure that bleeding is kept to a minimum.
  5. Specimen Retrieval: Once the tumor is removed, it is important to retrieve it intact for further analysis. The surgeon will use a specimen retrieval bag to remove the tumor and any surrounding tissue. The specimen is then sent to the pathology lab for analysis.
  6. Closure: After the tumor is removed, the surgeon will close the incisions. This is done using sutures, staples, or surgical glue. The incisions are small and usually do not require a drain.
  7. Advancements in Laparoendoscopic Surgery: Recent advancements in laparoendoscopic surgery for oncology include the use of robotic surgery and fluorescence imaging. Robotic surgery allows for more precise movements and better control of the surgical instruments. Fluorescence imaging uses a special dye that is injected into the patient to help identify cancerous tissue. This technique is particularly useful in identifying small tumors that may not be visible to the naked eye.

In conclusion, laparoendoscopic surgery is an important technique used in oncology for the removal of tumors and cancerous tissues. The procedure involves the placement of trocars, creation of a pneumoperitoneum, dissection and tumor removal, hemostasis, specimen retrieval, and closure. Recent advancements in laparoendoscopic surgery include the use of robotic surgery and fluorescence imaging. This technique provides several advantages over traditional open surgery, including reduced blood loss, faster recovery times, and fewer complications. It is important to discuss the benefits and risks of laparoendoscopic surgery with your doctor to determine if it is the best option for you.

How Marijuana Affects Brain Function

By
Marijuana is the most commonly used illicit drug in the United States. It is estimated that 50% of American teenagers have tried marijuana for the first time before they graduate from high school. The main culprit of marijuana’s harmful health effects boils down to THC. THC, which stands for tetrahydrocannabinol, elicits psychological effects when binding with the receptors on nerve cells and fits like a lock. These receptors are commonly found in particular regions of the brain associated with memory, pleasure, and thinking. This article runs down the effects of marijuana on brain performance and how chronic use of the drug affects the individual’s everyday life. Overview on Marijuana Street names: pot, weed, herb. Marijuana is made from Cannabis sativa, a hemp plant. People can take up marijuana through the smoke of the plant’s seeds, flowers, stems, and dried leaves, although marijuana can now be mixed into food. At present, marijuana can be brewed as a tea, and controversiall

Can employees be exempt from Medical Marijuana at a drug-free workplace

By
In a 2012 statistical finding released by the National Survey in Drug Use and Health , there were 9.8 million full-time Americans adults who use drugs in the workplace including medical marijuana . In a separate study, it is found out that more or less 50% of industrial accidents are related to marijuana consumption. Effects of Marijuana Use in Work Performance Despite the legal regulation of cannabis laboratories and dispensaries in few states, marijuana is still considered an illicit, strictly controlled drug under the federal law. Marijuana use in the workplace greatly affects the individual’s healthy, safety and productivity. Impaired thinking, reduced concentration, loss of balance and decreased reaction time are among the most known adverse affects of marijuana. Thus, every establishment strives for a drug free workplace recognizing the hazardous consequences of its use and its impact to the workers’ productivity. Note : Marijuana traces can be detected through blo

How long cocaine will show in a drug test

By
Technology plays a great part in helping to detect traces of cocaine through different advanced methods for drug testing, like using urine, blood, saliva and hair. You can detect the existence of cocaine using the following drug tests.  Urine Drug Test To know how long will cocaine show in a drug test, the subject can undergo urine test. It can detect even the slightest trace of cocaine in his urine. However, this will depend on the manner of the cocaine intake. When cocaine is snorted, its detection is possible between 4-10 hours after the intake. When cocaine is injected, its detection is still possible, even after almost a day of the cocaine intake. Cocaine metabolites can still be found even after 2 and ½ days of the intake at a cut off level of 300ng. These metabolites include Benzoylecgonine, ecgonine methyl ester and coca ethylene when cocaine was taken with alcohol. The urine test is done in collecting the urine of the subject and the urine is placed directly into a c
