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]

Though the risk of HIV transmission through oral sex is very low, but several factors might increase the risk, including sores in the mouth or vagina or on the penis, bleeding gums, having an oral contact with menstrual blood, and the presence of other sexually transmitted diseases. But still the risk is low. by the way better to think twice before having the Oralsex with strangers. because you are not safe 100%.
