Laparoscopic Colectomy
Laparoscopic Colectomy samer kareem 6,160 Views • 2 years ago

On the day of your surgery, your health care team will take you to a preparation room. Your blood pressure and breathing will be monitored. You may receive an antibiotic medication through a vein in your arm. You will then be taken to an operating room and positioned on a table. You'll be given a general anesthesia medication to put you in a sleep-like state so that you won't be aware during your operation. The surgical team will then proceed with your colectomy. Colon surgery may be performed in two ways: Open colectomy. Open surgery involves making a longer incision in your abdomen to access your colon. Your surgeon uses surgical tools to free your colon from the surrounding tissue and cuts out either a portion of the colon or the entire colon. Laparoscopic colectomy. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Your surgeon passes a tiny video camera through one incision and special surgical tools through the other incisions. The surgeon watches a video screen in the operating room as the tools are used to free the colon from the surrounding tissue. The colon is then brought out through a small incision in your abdomen. This allows the surgeon to operate on the colon outside of your body. Once repairs are made to the colon, the surgeon reinserts the colon through the incision. The type of operation you undergo depends on your situation and your surgeon's expertise. Laparoscopic colectomy may reduce the pain and recovery time after surgery. But not everyone is a candidate for this procedure. Also, in some situations your operation may begin as a laparoscopic colectomy, but circumstances may force your surgical team to convert to an open colectomy. Once the colon has been repaired or removed, your surgeon will reconnect your digestive system to allow your body to expel waste. Options may include: Rejoining the remaining portions of your colon. The surgeon may stitch the remaining portions of your colon together, creating what is called an anastomosis. Stool then leaves your body as before. Connecting your intestine to an opening created in your abdomen. The surgeon may attach your colon (colostomy) or small intestine (ileostomy) to an opening created in your abdomen. This allows waste to leave your body through the opening (stoma). You may wear a bag on the outside of the stoma to collect stool. This can be permanent or temporary. Connecting your small intestine to your anus. After removing both the colon and the rectum (proctocolectomy), the surgeon may use a portion of your small intestine to create a pouch that is attached to your anus (ileoanal anastomosis). This allows you to expel waste normally, though you may have several watery bowel movements each day. As part of this procedure, you may undergo a temporary ileostomy.

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,134 Views • 2 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

Edwards Syndrome
Edwards Syndrome samer kareem 3,924 Views • 2 years ago

Trisomy 18, also called Edwards syndrome, is a chromosomal condition associated with abnormalities in many parts of the body. Individuals with trisomy 18 often have slow growth before birth (intrauterine growth retardation) and a low birth weight. Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers. Due to the presence of several life-threatening medical problems, many individuals with trisomy 18 die before birth or within their first month. Five to 10 percent of children with this condition live past their first year, and these children often have severe intellectual disability.

Aortic Heart Valve Replacement Surgery
Aortic Heart Valve Replacement Surgery samer kareem 10,846 Views • 2 years ago

During open-heart valve surgery, the doctor makes a large incision in the chest. Blood is circulated outside of the body through a machine to add oxygen to it (cardiopulmonary bypass or heart-lung machine). The heart may be cooled to slow or stop the heartbeat so that the heart is protected from damage while surgery is done to replace the valve with an artificial valve. The artificial valve might be mechanical (made of man-made substances). Others are made out of animal tissue, often from a pig.
