Transoral Access in Endoscopic Thyroid Surgery
Transoral Access in Endoscopic Thyroid Surgery DrHouse 14,925 Views • 2 years ago

Transoral Access in Endoscopic Thyroid Surgery Background: The number of patients demanding endoscopic neck surgery is rising. The access trauma of the axillary, breast and chest approaches is bigger than in open or video assisted surgery. We tested the feasibility of he sublingual transoral access which is in our opinion the only real minimally...-invasive extracollar endoscopic access to the thyroid gland Methods: We performed an experimental investigation in a porcine model. In 10 pigs we made 10 endoscopic transoral thyroidectomys with a modified axilloscope with the help of ultrasonic scissors and a neuro-monitoring system for identification of the recurrent laryngeal nerve. Results: The average operation time from the introduction to the removal of the obturator just above the larynx was 57 seconds. The mean operation time was 43 minutes. With the help of the neuro-monitoring system we proved in all cases the function of the recurrent laryngeal nerve on both sides. The pigs were observed for another two hours after operation. During and after the operation no complications appeared. Conclusions: We could show that the endoscopic transoral thyroid resection in pigs is possible and save. Our results might be useful for using this access for endoscopic thyroid resection in humans.

Dual Sphincterotomy with a Needle Knife Over a Stent for Sphincter of Oddi Dysfunction Mohamed 17,511 Views • 2 years ago

This 38 year old woman has increasingly intractable RUQ pain after cholecystectomy done one year prior. LFTs and pancreatic enzymes have been normal, and ducts are non-dilated, thus she is a Type III possible SOD patient. Initial goal is to define course of pancreatic duct for manometry. 5-4-3 Co...ntour catheter (Boston Scientific) is used to perform the pancreatogram which shows a small straight distal duct. The aspirating triple lumen manometry catheter (Wilson Cook) is used to cannulate the pancreatic duct, with continuous aspiration of fluid once the duct is entered. Careful stationed pullthrough manometry shows markedly abnormal basal pressures in both leads in the pancreatic sphincter. Plan is dual pancreatic and biliary sphincterotomy. Biliary manometry will not now change our plan therefore is omitted. Our first goal is to access the pancreatic duct so we can guarantee wire access for placement of a small caliber pancreatic stent which is critical for safety. Contrast is injected as the 0.018in Roadrunner wire (Wilson Cook) is advanced in order to outline the course of main duct. A separate biliary orifice is clearly seen, unusual in SOD patients. A soft 4Fr 3cm single inner flange pancreatic stent (Hobbs Medical) is placed. We did not want to use our typical 9cm long unflanged stent as even a 3 or 4 French stent might be traumatic to the tiny caliber of this duct out in the body of the gland. Next the bile duct is cannulated with a papillotome (Autotome 39, Boston Scientific), showing a small perhaps 6mm bile duct. Biliary sphincterotomy is performed in very careful stepwise fashion as landmarks are unclear and perforation is higher risk in small duct SOD patients. On the other hand, inadequate sphincterotomies offer limited chance of symptom relief. You can see here a patulous sphincterotomy. Next a pancreatic sphincterotomy is performed with the needle knife (Boston Scientific) over the pancreatic stent. Again this is performed cautiously due to the small size of the pancreatic duct. We are reaching along the stent and cutting the fibers deeply. This is a limited pancreatic sphincterotomy due to small pancreatic duct size, and concern for scarring of the pancreatic duct. It is important to document passage of the stent by xray or remove it endoscopically with two weeks or so. We and many other specialized centers perform dual sphincterotomies at the first ERCP in all SOD patients with abnormal pancreatic manometry and frequent or intractable symptoms based on the belief that response rates are better than for biliary sphincterotomy alone.

This task requires streching a rubber band around 16 nails on a wooden board. A penalty is calculated when the rubber band is not streched around a nail at the end of the task. Score = time (seconds) + number of missed nails x 10. Performance standard: Score = 62 sec [Kolkman 2008]

Suture Burial Technique in Scleral Fixation
Suture Burial Technique in Scleral Fixation Scott 13,302 Views • 2 years ago

Scleral fixated IOLs in case of inadequacy of capsular support and scleral sutured capsular tension rings when adequate zonular support is inavailable have been recently used in cataract surgery. In these techniques, polypropylene suture is used and the suture ends over the sclera after the knot ha...s been formed, may erode the conjunctiva and become exposed. Thus, the erosion may lead to the development of endophtalmitis. In order to prevent the aforementioned complication, scleral flaps, otologous cornea, duramater or fascia lata patches have been used to cover the knot and rotation of the knot into the tissues has been described.

University Hospitals Neurological Institute will host a live webcast to demonstrate the removal of a brain tumor that doctors believe is causing epileptic seizures in a middle-aged man.

An MRI showed what appears to be a glioma (tumor) near a part of the brain that controls muscle movement, called the motor strip. Studies have shown that complete removal can cure the seizures and improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because it's difficult to determine where tumor ends and normal brain begins.
