The peroneal artery is closely positioned to the fibula. The artery arises from the tibioperoneal trunk, distal to the takeoff of the anterior tibial artery (seen in the illustration below perforating the interosseous membrane). The peroneal artery sends perforators laterally to the skin of the lower leg, sometimes in a septocutaneous fashion via the lateral intermuscular septum, but often with muscular perforators. The length of the pedicle is usually short, but can be increased substantially by dissecting the peroneal artery and its venae from the fibula and using the distal bone for reconstruction.

During surgery to repair the hernia, the bulging tissue is pushed back in. Your abdominal wall is strengthened and supported with sutures (stitches), and sometimes mesh. This repair can be done with open or laparoscopic surgery. You and your surgeon can discuss which type of surgery is right for you.

Cholesterol is a fat-like, waxy substance that can be found in all parts of your body. It helps your body make cell membranes, many hormones, and vitamin D. The cholesterol in your blood comes from two sources: the foods you eat and your liver. But your liver makes all the cholesterol your body needs.

Purpose: To evaluate the results of LASIK and IntraLASIK treatment in myopic patients with nystagmus. Methods: Eight patients with congenital nystagmus (16 eyes), from 23 to 49 years of age, underwent LASIK surgery. Corneal flaps were created using either the Hansatome microkeratome or the Intral...ase femtosecond laser. The ablations were performed with the Bausch & Lomb excimer laser with an active tracking system. In some patients, the eyes were fixated with forceps or a fixation ring during the laser ablation. Results: The refractive errors were corrected in all cases. There was no decentration or loss of best corrected visual acuity greater than 1 line. In 56% of the eyes, the post-operative uncorrected visual acuity was better than the best spectacle corrected-visual acuity (BSCVA). 62.5% of the eyes improved their BSCVA. The overall visual performance was improved in all the patients. One patient that did not not drive before become eligible to get a driver license after the surgery. Conclusions: Selected patients with myopia and congenital nystagmus may benefit from laser refractive surgery. Laser refractive surgery may be safely and accurately performed by using either the Hansatome microkeratome or the Intralase femtosecond laser and an active tracking system with or without mechanical fixation. Certain patients improve their BSCVA post-operatively.

Biliary and Pancreatic Sphincterotomies for Sphincter of Oddi Dysfunction

This 43 year old woman has severe recurrent RUQ pain post cholecystectomy. Liver and pancreatic chemistries and duct size are normal, but pancreatic manometry is abnormal. The plan is to perform dual biliary and pancreatic sphincterotomy. The pancreatic duct is cannulated with a 3.9 French tip tr...iple lumen papillotome loaded with a 0.025 inch Jagwire. Contrast is injected to outline the course of the duct. The wire is passed to the tail. Notice the knuckling of the wire into the tail. This provides a safety loop, but is only safe in a small duct with use of a smaller caliber wire. Then with the wire securely in PD, papillotome is used to cannulate the bile duct. Placement of the wire in PD guarantees access for pancreatic stent placement, which is mandatory in these patients to reduce risk, it also facilitates difficult biliary cannulation. Here is the fluoroscopic view as the papillotome is passed deep into bile duct. This shows wires in the CBD and PD. Now a biliary sphincterotomy is performed, with the pancreatic guidewire in place beside the papillotome. The scope is pushed into a longer position to orient up the middle of the papilla. The sphincterotomy is done in very careful stepwise fashion to avoid perforation. Now the biliary wire is removed and the papillotome passed over the pancreatic wire for pancreatic sphincterotomy. The incision is aimed back up towards the biliary sphincterotomy to ensure the septum only is cut. Note the large pancreatic orifice. Last, a 4 French 9cm unflanged soft material pancreatic stent is placed. We always use single pigtail design to avoid inward migration of the stent. The long unflanged design allows spontaneous passage within a few weeks.

Ultrasound-guided internal jugular cannulation

Surgical technique: A 3cm skin incision under spinal or general anesthesia, depending on the patients’ preference, starts half way the line between the superior anterior iliac spine towards the midline in a 30° angle to the pubic tubercle. Scarpa’s fascia is opened as well as the external obliq...ue aponeurosis. By using this skin line incision the internal ring will be immediately visualized. Although it is important to look for both direct and indirect hernias evaluating the groin, we do not taper the cord and directly evaluate the ring for indirect hernias. In case of an indirect hernia the sac is reduced or resected according to the preference of the surgeon and the preperitoneal space is entered bluntly through the dilated internal ring. In case of a direct hernia the approach slightly differs. One could prefer to open the transversalis fascia through the internal ring over a few centimeters or you can open the fascia more medially, at the site of the direct hernia. As primary point of concern the epigastric vessels should be identified and retracted softly upwards. Then a gauze can be introduced into the preperitoneal space and by doing so most of the space needed medially will be created. Then one can already palpate Cooper’s ligament and the pubic bone. Laterally to the internal ring more digital dissection is needed to create just the appropriate space for the mesh. By placing the mesh it is important not to introduce the mesh too medially. Laterally of the internal ring an adequate overlap of the mesh is necessary, especially in indirect hernias. No splitting of the mesh seems necessary. The patient will be asked to strain and push on the ring to control its place and to check adequate spreading of the mesh to cover the whole myopectineum of Fruchaud. One single stitch of vicryl 3/0 is placed taking both the fascia transversalis and the mesh.

A prenatal ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements. (Ultrasound waves are also used in the handheld instrument called a Doppler that your practitioner uses during your prenatal visits to listen to your baby's heartbeat.) You may have an early ultrasound at your practitioner's office at 6 to 10 weeks to confirm and date the pregnancy. Or you may not have one until the standard midpregnancy ultrasound between 16 and 20 weeks. That's when you may learn your baby's sex, if you like. (The technician will probably present you with a grainy printout of the sonogram as a keepsake.) You may also have a sonogram as part of a genetic test, such as the nuchal translucency test, chorionic villus sampling, or amniocentesis, or at any other time if there are signs of a problem with your baby. You'll have more frequent ultrasounds if you have diabetes, hypertension, or other medical complications.

The kidneys are a pair of organs located in the back of the abdomen. Each kidney is about 4 or 5 inches long -- about the size of a fist. The kidneys' function are to filter the blood. All the blood in our bodies passes through the kidneys several times a day. The kidneys remove wastes, control the body's fluid balance, and regulate the balance of electrolytes. As the kidneys filter blood, they create urine, which collects in the kidneys' pelvis -- funnel-shaped structures that drain down tubes called ureters to the bladder. Each kidney contains around a million units called nephrons, each of which is a microscopic filter for blood. It's possible to lose as much as 90% of kidney function without experiencing any symptoms or problems.
