Laparoscopy (from Ancient Greek λαπάρα (lapára) 'flank, side', and σκοπέω (skopéō) 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.[1]

Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time. The key element is the use of a laparoscope, a long fiber optic cable system that allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location.

Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Specific surgical instruments used in laparoscopic surgery include obstetrical forceps, scissors, probes, dissectors, hooks, and retractors. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. The first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901. There are two types of laparoscope:[2]

A telescopic rod lens system, usually connected to a video camera (single-chip or three-chip)
A digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system

The mechanism mentioned in the second type is mainly used to improve the image quality of flexible endoscopes, replacing conventional fiberscopes. Nevertheless, laparoscopes are rigid endoscopes. Rigidity is required in clinical practice. The rod-lens-based laparoscopes dominate overwhelmingly in practice, due to their fine optical resolution (50 µm typically, dependent on the aperture size used in the objective lens), and the image quality can be better than that of the digital camera if necessary. The second type of laparoscope is very rare in the laparoscope market and in hospitals.[citation needed]

Also attached is a fiber optic cable system connected to a "cold" light source (halogen or xenon) to illuminate the operative field, which is inserted through a 5 mm or 10 mm cannula or trocar. The abdomen is usually insufflated with carbon dioxide gas. This elevates the abdominal wall above the internal organs to create a working and viewing space. CO2 is used because it is common to the human body and can be absorbed by tissue and removed by the respiratory system. It is also non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures.[3]

Patient position

During the laparoscopic procedure, the position of the patient is either in Trendelenburg position or in reverse Trendelenburg. These positions have an effect on cardiopulmonary function. In Trendelenburg's position, there is an increased preload due to an increase in the venous return from lower extremities. This position results in cephalic shifting of the viscera, which accentuates the pressure on the diaphragm. In the case of reverse Trendelenburg position, pulmonary function tends to improve as there is a caudal shifting of viscera, which improves tidal volume by a decrease in the pressure on the diaphragm. This position also decreases the preload on the heart and causes a decrease in the venous return leading to hypotension. The pooling of blood in the lower extremities increases the stasis and predisposes the patient to develop deep vein thrombosis (DVT).[4]
Gallbladder

Rather than a minimum 20 cm incision as in traditional (open) cholecystectomy, four incisions of 0.5–1.0 cm, or more recently, a single incision of 1.5–2.0 cm,[5] will be sufficient to perform a laparoscopic removal of a gallbladder. Since the gallbladder is similar to a small balloon that stores and releases bile, it can usually be removed from the abdomen by suctioning out the bile and then removing the deflated gallbladder through the 1 cm incision at the patient's navel. The length of postoperative stay in the hospital is minimal, and same-day discharges are possible in cases of early morning procedures.[citation needed]

Although your body may harbor the bacteria that cause tuberculosis, your immune system usually can prevent you from becoming sick. For this reason, doctors make a distinction between: Latent TB. In this condition, you have a TB infection, but the bacteria remain in your body in an inactive state and cause no symptoms. Latent TB, also called inactive TB or TB infection, isn't contagious. It can turn into active TB, so treatment is important for the person with latent TB and to help control the spread of TB. An estimated 2 billion people have latent TB. Active TB. This condition makes you sick and can spread to others. It can occur in the first few weeks after infection with the TB bacteria, or it might occur years later. Signs and symptoms of active TB include: Coughing that lasts three or more weeks Coughing up blood Chest pain, or pain with breathing or coughing Unintentional weight loss Fatigue Fever Night sweats

The Epley maneuver is a series of movements, normally carried out on a person by a doctor, to relieve the symptoms of BPPV. Research has found it to be an easy, safe, and effective treatment for the condition in both the long- and short-term. The Epley maneuver is sometimes called the particle repositioning maneuver or the canalith repositioning maneuver. These names are used because the maneuver involves a series of movements that help to reposition crystals in a person's ear that may cause feelings of dizziness. Repositioning the crystals helps to relieve the person's dizziness and nausea.

Director of the Penn Orthopaedics Robotics and Navigation Program, Dr. Christopher Travers, discusses robotic joint replacement surgery, which is one of the multiple options that Penn Orthopaedics offers for joint replacement surgery. He walks through a robotic knee replacement surgery, discussing what the procedure is, how it differs from traditional joint replacement surgery, and the benefits.

Frontotemporal dementia is the name for a range of conditions in which cells in the frontal and temporal lobes of the brain are damaged. These lobes control behaviour, emotional responses and language. This means that people will experience changes in personality and behaviour, or may struggle with language – for example, in finding the right word. Frontotemporal dementia is a less common form of dementia which is more likely to affect younger people – those under 65.

This video demonstrate Laparoscopic Cholecystectomy Full Length Skin to Skin Video with Infrared Cholangiography performed by Dr R K Mishra at World Laparoscopy Hospital. Infrared Cholegiography is performed by using Indocyanine Green during laparoscopic cholecystectomy surgery for gallbladder removal. Bile duct injury remains the most feared complication of laparoscopic cholecystectomy. Intraoperative cholangiography (IOC) is the current gold standard for biliary imaging and may reduce injury, but is not widely used because of the difficulties of doing it. Near-Infrared Fluorescence Cholangiography (NIRF-C) is a novel non-invasive method for real-time, radiation-free, intra-operative biliary mapping during laparoscopic cholecystectomy. We have experienced that NIRF-C is a safe and effective method for identifying biliary anatomy during laparoscopic cholecystectomy. Indocyanine green is a cyanine dye is very popular and used for many years in medical diagnostics. It is used for determining cardiac output, hepatic function, liver, and gastric blood flow, and for ophthalmic angiography. Now the use of this dye in lap chole has improved the safety of this surgery by NEAR INFRARED FLUORESCENT CHOLANGIOGRAPHY.

For this surgery, your doctor makes a large incision in the abdomen to expose the aorta. Once he or she has opened the abdomen, a graft can be used to repair the aneurysm. Open repair remains the standard procedure for an abdominal aortic aneurysm repair. Endovascular aneurysm repair (EVAR).

Use warm water and sea salt. Soak the wart for 10 to 15 minutes in warm salt water to moisten the skin. Scrape the dead skin layers off the wart using a nail file, pumice stone or mild sandpaper. You could also use your fingers, but wash them thoroughly before and after, as warts can easily spread.
