Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing.

What is Laparoscopic Surgery:
Laparoscopic surgery describes procedures performed using one or multiple small incisions in the abdominal wall in contrast to the larger, normally singular incision of laparotomy. The technique is based around principles of minimally invasive surgery (or minimal access surgery): a large group of modern surgical procedures carried out by entering the body with the smallest possible damage to tissues. In abdominopelvic surgery, minimally invasive surgery is generally treated as synonymous with laparoscopic surgery as are procedures not technically within the peritoneal cavity, such as totally extraperitoneal hernia repair, or extending beyond the abdomen, such as thoraco-laparoscopic esophagectomy. The term laparoscopy is sometimes used interchangeably, although this is often reserved to describe a visual examination of the peritoneal cavity or the purely scopic component of a laparoscopic procedure. The colloquial keyhole surgery is common in non-medical usage.
Surgical Objective of Laparoscopic Surgery:
The objective of a laparoscopic approach is to minimize surgical trauma when operating on abdominal or pelvic structures. When correctly indicated and performed, this can result in smaller scars, reduced postoperative morbidity, shorter inpatient durations, and a faster return to normal activity. For a number of abdominopelvic procedures, a laparoscopic approach is now generally considered to be the gold-standard treatment option.

Developments of Laparoscopic Surgery:
Following a number of smaller-scale applications of minimally invasive techniques to abdominopelvic surgery, laparoscopic surgery became a major part of general surgical practice with the introduction of laparoscopic cholecystectomy in the 1980s and the subsequent pioneering of endoscopic camera technology. This led to the widespread adoption of the technique by the early- to mid-1990s. The portfolio of procedures that can be performed laparoscopically has rapidly expanded with improvements in instruments, imaging, techniques and training — forming a central component of modern surgical practice and cross-specialty curricula [2]. Techniques such as laparoscopically assisted surgery and hand-assisted laparoscopic surgery have allowed the application of laparoscopic techniques to a greater variety of pathology. Single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and minilaparoscopy-assisted natural orifice surgery continue to push forward the applications of minimally invasive abdominopelvic techniques; however, the widespread practice and specific indications for these remain to be fully established. More recently, robotic surgery has been able to build on laparoscopic principles through developments in visualization, ergonomics, and instrumentation.

A stapled haemorrhoidopexy is an operation to return the haemorrhoids to a normal. position inside the rectum (back passage). A circular shaped stapling device is gently. inserted in the back passage. The surgeon is then able to use the device to remove.
With keratoconus, the clear, dome-shaped tissue that covers the eye (cornea) thins and bulges outward into a cone shape. Its cause is unknown. Symptoms first appear during puberty or the late teens and include blurred vision and sensitivity to light and glare. Vision can be corrected with glasses or contact lenses early on. Advanced cases may require a cornea transplant.
An amputation is the removal of an extremity or appendage from the body. Amputations in the upper extremity can occur as a result of trauma, or they can be performed in the treatment of congenital or acquired conditions. Although successful replantation represents a technical triumph to the surgeon, the patient's best interests should direct the treatment of amputations. The goals involved in the treatment of amputations of the upper extremity include the following : Preservation of functional length Durable coverage Preservation of useful sensibility Prevention of symptomatic neuromas Prevention of adjacent joint contractures Early return to work Early prosthetic fitting These goals apply differently to different levels of amputation. Treatment of amputations can be challenging and rewarding. It is imperative that the surgeon treat the patient with the ultimate goal of optimizing function and rehabilitation and not become absorbed in the enthusiasm of the technical challenge of the replantation, which could result in poorer outcome and greater financial cost due to lost wages, hospitalization, and therapy.
Nose cautery can help prevent nosebleeds. The doctor uses a chemical swab or an electric current to cauterize the inside of the nose. This seals the blood vessels and builds scar tissue to help prevent more bleeding. For this procedure, your doctor made the inside of your nose numb.
Soft tissue biopsy from osteolytic lesions is a challenge for the interventionist. The Spirotome Bone is conceived for this intervention. The procedure is straigthforward and produces tissue specimens of high quality in sufficient amounts to allow quantitative molecular biology.
