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]
Procedures

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]

Attention-deficit/hyperactivity disorder (ADHD) is a chronic condition that affects millions of children and often continues into adulthood. ADHD includes a combination of persistent problems, such as difficulty sustaining attention, hyperactivity and impulsive behavior.
A decade ago we thought that Chikungunya was a tropical disease restricted to the rain forests. However, after the 2007 epidemic in Italy and later in the Reunion islands, this dreaded condition has now spread to the Carribean and the Americas. Its an arthropod borne alpha virus which causes fever, polyarthralgia and arthritis. There could be serious complications in the adult such as meningoencephalitis or GBS as well as in neonates. This presentation discusses in detail the clinical features, diagnosis and management of Chikungunya fever. A detailed discussion of its complications is also included. Check out our other videos
Shoulder Clinical Examination - Medical School Clinical Skills - Dr Gill
Personally, I find the shoulder examination the most complex examination possibly as there are so many variations and special tests. Some of which overlap and some will relate specifically to a patients presentation.
Often in a medical school syllabus, only select special tests will be used. In this shoulder exam demonstration, we include the Hawkins-Kennedy Test looking for impingement. This is dovetailed with examination for bicipital tendonitis as this is another possible cause of impingement type symptoms.
This shoulder upper limb exam follows the standard "Look, Feel, Move" orthopaedic exam approach, and overall order as set out in MacLeods Clinical Examination

________
Please note that there is no ABSOLUTE way to perform a clinical examination. Different institutions and even clinicians will have differing degrees of variations - the aim is the effectively identify medically relevant signs.
However during OSCE assessments. Different medical schools, nursing colleges, and other health professional courses will have their own preferred approach to a clinical assessment - you should concentrate on THEIR marks schemes for your assessments.
The examination demonstrated here is derived from Macleods Clinical Examination - a recognized standard textbook for clinical skills.

our uterus (or womb) is normally held in place inside your pelvis with various muscles, tissue, and ligaments. Because of pregnancy, childbirth or difficult labor and delivery, in some women these muscles weaken. Also, as a woman ages and with a natural loss of the hormone estrogen, her uterus can drop into the vaginal canal, causing the condition known as a prolapsed uterus.
Ovulation is the release of eggs from the ovaries. In humans, this event occurs when the follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm
Watch Spinal Stenosis Videos Spinal stenosis occurs when the spinal cord in the neck (cervical spine) or the spinal nerve roots in the lower back (lumbar spine) are compressed. Symptoms of lumbar stenosis often include leg pain (sciatica) and leg tingling, weakness, or numbness. Arm pain is a typical symptom of cervical spinal stenosis. For cervical spinal stenosis with myelopathy, difficulty with coordination often occurs. Stenosis treatment may include non-surgical options (exercise, anti-inflammatory medication, epidural injections, and activity modification) or back surgery.
Microsurgical bipolar cautery tonsillectomy compares favorably with traditional techniques in terms of intraoperative bleeding, postoperative pain, otalgia, and hemorrhage. This technique combines the hemostatic advantage of cautery dissection, the excellent visualization achieved by a microscope, and, with the use of a video, greatly improves the physician's ability to teach how to perform a tonsillectomy.
