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
Surgeons perform laparoscopic stomach surgery.
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]

A hematoma is a common complication of surgical procedures. A large, expanding hematoma can result in necrosis of the overlying skin (1,2) or adjacent subcutaneous fat, increased incidence of infection, scarring, skin hyperpigmentation, tissue edema and a prolonged convalescence.
Surgical site infections (SSIs) remain a prevalent threat to patient safety. Proper surgical hand scrub or rub techniques are essential to decreasing the incidence of SSIs. This video provides instructions on the anatomical surgical hand scrub procedure using the brushstroke method.

Excerpt from my Normal Skin Histology video: https://kikoxp.com/posts/3660.
A complete organized library of all my videos, digital slides, pics, & sample pathology reports is available here: https://kikoxp.com/posts/5084 (dermpath) & https://kikoxp.com/posts/5083 (bone/soft tissue sarcoma pathology).

Also, in the past I used "keratinocyte" and "squamous cell" interchangeably (this is because in dermatopathology, we see and talk about squamous cell carcinomas all the time, and those tumors are composed of keratinocytes). But technically, in normal skin histology, "squamous cell" refers only to the flattened keratinocytes in the superficial epidermis. Thankfully, a histology PhD colleague pointed this out to me and corrected my lazy nomenclature!
This video is geared towards medical students, pathology or dermatology residents, or practicing pathologists or dermatologists. Of course, this video is for educational purposes only and is not formal medical advice or consultation.

An ectopic pregnancy (EP) is a condition in which a fertilized egg settles and grows in any location other than the inner lining of the uterus. The vast majority of ectopic pregnancies are so-called tubal pregnancies and occur in the Fallopian tube.
A VCUG (Voiding Cystourethrogram) is a test that looks at how well your child's kidneys, ureters and bladder are working. Your child's kidneys make urine. The urine flows from the kidneys through thin tubes (called ureters) into your child's bladder.
A c-section, or cesarean section, is the delivery of a baby through a surgical incision in the mother's abdomen and uterus. In some circumstances, a c-section is scheduled in advance. In others, the surgery is needed due to an unforeseen complication. If you or your baby is in imminent danger, you'll have an emergency c-section. Otherwise, it's called an unplanned section. According to the U.S. Centers for Disease Control, about 32 percent of American women who gave birth in 2015 had a cesarean delivery.
Many U.S. hospitals still perform traditional surgery, over minimally invasive procedures, according to Johns Hopkins University researchers. Also, a new study on HPV vaccines. Wendy Gillette reports on the day's top health stories.
