Stay Sutures
Stay sutures are temporary surgical sutures which are placed during operation to hold or manipulate the operating area. In cases of ocular surgery, tracheostomy, suprapubic cystolithotomy, appendicectomy, ureterolithotomy, or choledocholithotomy stay sutures can be given. They can be used to temporarily align a structure to stabilize it. This can allow a surgeon to work more safely around the area, without the possibility of a clamp slipping and falling out of place. Stay sutures can also limit bleeding in an area where key vessels may be disturbed. Usually they are removed at the end of the surgery prior to the closure of the incision, although they may be left in place if the surgeon feels they pose no risk to the patient. They can also be placed at the end of strabismus surgery to avoid that the eye drifts back to its original position. Stay sutures can sometimes be used in the management of surgical emergencies. Stay sutures are kept in place with the help of hemostatic artery f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Suture
A surgical suture, also known as a stitch or stitches, is a medical device used to hold Tissue (biology), body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a Sewing needle, needle with an attached length of thread (yarn), thread. There are numerous types of suture which differ by needle shape and size as well as thread material and characteristics. Selection of surgical suture should be determined by the characteristics and location of the wound or the specific body tissues being approximated. In selecting the needle, thread, and suturing technique to use for a specific patient, a medical care provider must consider the tensile strength of the specific suture thread needed to efficiently hold the tissues together depending on the mechanical and shear forces acting on the wound as well as the thickness of the tissue being approximated. One must also consider the elasticity of the thread and ability to adapt to differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocular Surgery
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage. An eye surgeon is responsible for selecting the appropriate surgical procedure for the patient, and for taking the necessary safety precautions. Mentions of eye surgery can be found in several ancient texts dating back as early as 1800 BC, with cataract treatment starting in the fifth century BC. It continues to be a widely practiced class of surgery, with various techniques having been developed for treating eye problems. Preparation and precautions Since the eye is heavily supplied by nerves, anesthesia is essential. Local anesthesia is most commonly used. Topical anesthesia using lidocaine topical gel is often used for quick procedures. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracheostomy
Tracheotomy (, ), or tracheostomy, is a surgical airway management procedure which consists of making an incision on the front of the neck to open a direct airway to the trachea. The resulting stoma (hole) can serve independently as an airway or as a site for a tracheal tube (or tracheostomy tube) to be inserted; this tube allows a person to breathe without the use of the nose or mouth. Etymology and terminology The etymology of the word ''tracheotomy'' comes from two Greek words: the root ''tom-'' (from Greek τομή ''tomḗ'') meaning "to cut", and the word ''trachea'' (from Greek τραχεία ''tracheía''). The word ''tracheostomy'', including the root ''stom-'' (from Greek στόμα ''stóma'') meaning "mouth", refers to the making of a semi-permanent or permanent opening and to the opening itself. Some sources offer different definitions of the above terms. Part of the ambiguity is due to the uncertainty of the intended permanence of the stoma (hole) at the time it ...

Cystolithotomy
A bladder stone is a stone found in the urinary bladder. Signs and symptoms Bladder stones are small mineral deposits that can form in the bladder. In most cases bladder stones develop when the urine becomes very concentrated or when one is dehydrated. This allows for minerals, such as calcium or magnesium salts, to crystallize and form stones. Bladder stones vary in number, size and consistency. In some cases bladder stones do not cause any symptoms and are discovered as an incidental finding on a plain radiograph. However, when symptoms do occur, these may include severe lower abdominal and back pain, difficult urination, frequent urination at night, fever, painful urination and blood in the urine. The majority of individuals who are symptomatic will complain of pain which comes in waves. The pain may also be associated with nausea, vomiting and chills.

Appendicectomy
An appendectomy (American English) or appendicectomy (British English) is a surgical operation in which the vermiform appendix (a portion of the intestine) is removed. Appendectomy is normally performed as an urgent or emergency procedure to treat complicated acute appendicitis. Appendectomy may be performed laparoscopically (as minimally invasive surgery) or as an open operation. Over the 2010s, surgical practice has increasingly moved towards routinely offering laparoscopic appendicectomy; for example in the United Kingdom over 95% of adult appendicectomies are planned as laparoscopic procedures. Laparoscopy is often used if the diagnosis is in doubt, or in order to leave a less visible surgical scar. Recovery may be slightly faster after laparoscopic surgery, although the laparoscopic procedure itself is more expensive and resource-intensive than open surgery and generally takes longer. Advanced pelvic sepsis occasionally requires a lower midline laparotomy. Complicated (perfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Choledocholithotomy
A gallstone is a calculus (medicine), stone formed within the gallbladder from precipitated bile components. The term cholelithiasis may refer to the presence of gallstones or to any disease caused by gallstones, and choledocholithiasis refers to the presence of migrated gallstones within bile ducts. Most people with gallstones (about 80%) are asymptomatic. However, when a gallstone obstructs the bile duct and causes acute cholestasis, a reflexive smooth muscle spasm often occurs, resulting in an intense cramp-like visceral pain in the quadrant (abdomen), right upper part of the abdomen known as a biliary colic (or "gallbladder attack"). This happens in 1–4% of those with gallstones each year. Complications from gallstones may include inflammation of the gallbladder (cholecystitis), inflammation of the pancreas (pancreatitis), Jaundice#Post-hepatic, obstructive jaundice, and infection in bile ducts (ascending cholangitis, cholangitis). Symptoms of these complications may inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strabismus Surgery
Strabismus surgery (also: ''extraocular muscle surgery'', ''eye muscle surgery'', or ''eye alignment surgery'') is surgery on the extraocular muscles to correct strabismus, the misalignment of the human eye, eyes. Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home. History The earliest successful strabismus surgery intervention is known to have been performed on 26 October 1839 by Johann Friedrich Dieffenbach on a 7-year-old esotropic child; a few earlier attempts had been performed in 1818 by William Gibson of Baltimore, a general surgeon and professor at the University of Maryland. The idea of treating strabismus by cutting some of the extraocular muscle fibers was published in American n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cervical Cerclage
Cervical cerclage, also known as a cervical stitch, is a treatment for cervical weakness, when the cervix starts to shorten and open too early during a pregnancy causing either a late miscarriage or preterm birth. In women with a prior spontaneous preterm birth and who are pregnant with one baby, and have shortening of the cervical length less than 25 mm, a cerclage prevents a preterm birth and reduces death and illness in the baby. The treatment consists of a strong suture sewn into and around the cervix early in the pregnancy, usually between weeks 12 to 14, and then removed towards the end of the pregnancy when the greatest risk of miscarriage has passed. The procedure is performed under local anaesthesia, usually by way of a spinal block. It is typically performed on an outpatient basis by an obstetrician-gynecologist. Usually the treatment is done in the first or second trimester of pregnancy, for a woman who has had one or more late miscarriages in the past. The word ...
