Morcellation
A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. In laparoscopic hysterectomy the uterus is cut up in strips, or morcellated, into smaller pieces inside the patient's abdominal cavity in order to extract from the abdomen. It can consist of a hollow cylinder that penetrates the abdominal wall, ending with sharp edges or cutting jaws, through which a grasper can be inserted to pull the mass into the cylinder to cut out an extractable piece. Surgery Laparoscopic morcellation is commonly used at surgery to remove bulky specimens from the abdomen using minimally invasive techniques. Historically, morcellation was performed using a device that required the surgeon or assistant to manually 'squeeze' the handle. Other reports describe using a scalpel directly through the abdomen to create small specimens that can be drawn out of the abdominal cavity. In 1993, the first electric morcellator was introduced in the US ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hysterectomy
Hysterectomy is the surgical removal of the uterus. It may also involve removal of the cervix, ovaries (oophorectomy), Fallopian tubes (salpingectomy), and other surrounding structures. Usually performed by a gynecologist, a hysterectomy may be total (removing the body, fundus, and cervix of the uterus; often called "complete") or partial (removal of the uterine body while leaving the cervix intact; also called "supracervical"). Removal of the uterus renders the patient unable to bear children (as does removal of ovaries and fallopian tubes) and has surgical risks as well as long-term effects, so the surgery is normally recommended only when other treatment options are not available or have failed. It is the second most commonly performed gynecological surgical procedure, after cesarean section, in the United States. Nearly 68 percent were performed for conditions such as endometriosis, irregular bleeding, and uterine fibroids. It is expected that the frequency of hysterectom ...

Surgical Instrument
A surgical instrument is a tool or device for performing specific actions or carrying out desired effects during a surgery or operation, such as modifying biological tissue, or to provide access for viewing it. Over time, many different kinds of surgical instruments and tools have been invented. Some surgical instruments are designed for general use in all sorts of surgeries, while others are designed for only certain specialties or specific procedures. Classification of surgical instruments helps surgeons to understand the functions and purposes of the instruments. With the goal of optimizing surgical results and performing more difficult operations, more instruments continue to be invented in the modern era. History Many different kinds of surgical instruments and tools have been invented and some have been repurposed as medical knowledge and surgical practices have developed. As surgery practice diversified, some tools are advanced for higher accuracy and stability while som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterine Fibroid
Uterine fibroids, also known as uterine leiomyomas or fibroids, are benign smooth muscle tumors of the uterus. Most women with fibroids have no symptoms while others may have painful or heavy periods. If large enough, they may push on the bladder, causing a frequent need to urinate. They may also cause pain during penetrative sex or lower back pain. A woman can have one uterine fibroid or many. Occasionally, fibroids may make it difficult to become pregnant, although this is uncommon. The exact cause of uterine fibroids is unclear. However, fibroids run in families and appear to be partly determined by hormone levels. Risk factors include obesity and eating red meat. Diagnosis can be performed by pelvic examination or medical imaging. Treatment is typically not needed if there are no symptoms. NSAIDs, such as ibuprofen, may help with pain and bleeding while paracetamol (acetaminophen) may help with pain. Iron supplements may be needed in those with heavy periods. Medica ...

Instruments Used In General Surgery
There are many different surgical specialties, some of which require very specific kinds of surgical instruments to perform. General surgery is a specialty focused on the abdominal contents, as well as the thyroid gland, and diseases involving skin, breasts, various soft tissues, trauma, peripheral vascular disease, hernias, and endoscopic procedures. This page is dedicated specifically to listing surgical instruments used in general surgery. Instruments can be classified in many ways - but broadly speaking, there are five kinds of instruments. # Cutting and dissecting instruments: #*Scalpels, scissors, and saws are the most traditional #*Elevators can be both cutting and lifting/retracting #*Although the term dissection is broad, energy devices such as diathermy/cautery are often used as more modern alternatives. # Grasping or holding instruments: #*Classically this included forceps and clamps predominantly #*Roughly, forceps can be divided into traumatic (tissue crushin ...

Metastasis
Metastasis is a pathogenic agent's spread from an initial or primary site to a different or secondary site within the host's body; the term is typically used when referring to metastasis by a cancerous tumor. The newly pathological sites, then, are metastases (mets). It is generally distinguished from cancer invasion, which is the direct extension and penetration by cancer cells into neighboring tissues. Cancer occurs after cells are genetically altered to proliferate rapidly and indefinitely. This uncontrolled proliferation by mitosis produces a primary heterogeneic tumour. The cells which constitute the tumor eventually undergo metaplasia, followed by dysplasia then anaplasia, resulting in a malignant phenotype. This malignancy allows for invasion into the circulation, followed by invasion to a second site for tumorigenesis. Some cancer cells known as circulating tumor cells acquire the ability to penetrate the walls of lymphatic or blood vessels, after which they are abl ...

Paracrine
Paracrine signaling is a form of cell signaling, a type of cellular communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells. Signaling molecules known as paracrine factors diffuse over a relatively short distance (local action), as opposed to cell signaling by endocrine factors, hormones which travel considerably longer distances via the circulatory system; juxtacrine interactions; and autocrine signaling. Cells that produce paracrine factors secrete them into the immediate extracellular environment. Factors then travel to nearby cells in which the gradient of factor received determines the outcome. However, the exact distance that paracrine factors can travel is not certain. Although paracrine signaling elicits a diverse array of responses in the induced cells, most paracrine factors utilize a relatively streamlined set of receptors and pathways. In fact, different organs in the body - even between different spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Predisposition
A genetic predisposition is a genetic characteristic which influences the possible phenotypic development of an individual organism within a species or population under the influence of environmental conditions. In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, which may eventually be triggered by particular environmental or lifestyle factors, such as tobacco smoking or diet. Genetic testing is able to identify individuals who are genetically predisposed to certain diseases. Behavior Predisposition is the capacity humans are born with to learn things such as language and concept of self. Negative environmental influences may block the predisposition (ability) one has to do some things. Behaviors displayed by animals can be influenced by genetic predispositions. Genetic predisposition towards certain human behaviors is scientifically investigated by attempts to identify patterns of human behavior that seem to be invariant ...

Leiomyoma
A leiomyoma, also known as a fibroid, is a benign smooth muscle tumor that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus. Polycythemia may occur due to increased erythropoietin production as part of a paraneoplastic syndrome. The word is from '' leio-'' + '' myo-'' + '' -oma'', "smooth-muscle tumor". The plural form can be either the English leiomyomas or the classical leiomyomata. Uterus Uterine fibroids are leiomyomata of the uterine smooth muscle. As other leiomyomata, they are benign, but may lead to excessive menstrual bleeding (menorrhagia), often cause anemia and may lead to infertility. A rare form of these tumors is uterine lipoleiomyoma—benign tumors consisting of a mixture of adipocytes and smooth muscle cells. Uterine lipoleiomyomata have been observed together with ovarian and other pathologies and some of them may develop into liposarcoma. These tumors are monoclona ...

Myomectomy
Myomectomy, sometimes also called fibroidectomy, refers to the surgical removal of uterine leiomyomas, also known as fibroids. In contrast to a hysterectomy, the uterus remains preserved and the woman retains her reproductive potential. Indications The presence of a fibroid does not mean that it needs to be removed. Removal is necessary when the fibroid causes pain or pressure, abnormal bleeding, or interferes with reproduction. The fibroids needed to be removed are typically large in size, or growing at certain locations such as bulging into the endometrial cavity causing significant cavity distortion. Treatment options for uterine fibroids include observation or medical therapy, such a GnRH agonist, hysterectomy, uterine artery embolization, and high-intensity focused ultrasound ablation. Procedure A myomectomy can be performed in a number of ways, depending on the location, size and number of lesions and the experience and preference of the surgeon. Either a general or a spi ...
