Mesh repair is based on the anatomical principle with associated complications of a foreign body and recurrence. Use of an un-detached strip of the external oblique aponeurosis in place of mesh between the muscle arch and the inguinal ligament gives a strong and physiologically dynamic posterior wal...l that gives radical cure.

What is a Whipple procedure?
Also called a pancreaticoduodenectomy, the Whipple procedure is performed to address chronic pancreatitis and cancer of the pancreas, ampulla of Vater, duodenum, and the distal bile duct. The Whipple procedure involves removing the cancerous parts of the pancreas, duodenum, common bile duct, and if required, part of the stomach.

Surgical technique: A 3cm skin incision under spinal or general anesthesia, depending on the patientsโ€™ preference, starts half way the line between the superior anterior iliac spine towards the midline in a 30ยฐ angle to the pubic tubercle. Scarpaโ€™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 Cooperโ€™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.

We noticed a blue-line in the endometrial cavity between the tubal ostiae after injection of methylene blue (to determine tubal patency). We have seen this โ€œblue-lineโ€ even in cases with normal or unicornuate uterus and/or in cases with patent or occluded fallopian tubes(Picture 1). So the be...st explanation of this finding may be the high speed jet or turbulence of dye in the top or the deepest part of endometrial cavity. We simply postulated that the zone which holds the methylene blue is the zone where the flashing dye strikes vertically over there and the dye penatrates into the endometrial epithelium and glands. We used this line as a guide that shows midline during operative hysteroscopy ( especially in cases with septate uterus) and we donโ€™t ecxatly know reason why it occurs. It is necessary to perform histologic, molecular or clinical studies on this subject. It may have a multifactorial aetiology. We performed a prospective case control study and will publish it soon after when we get the results.

Repair performed with the PROLIFT Pelvic Floor Repair System - the total implant. The objective of the PROLIFT procedure is to achieve a a complete anatomic repair of pelvic floor defects in a standardized way. The repair is achieved by the placement of the synthetic non-absorbable polyprolylen mesh... implant via a vaginal approach.

Here Drs Oetting and Shriver of the University of Iowa demonstrate the McCannel technique of fixing an IOL to the iris. In this video both the standard McCannel suture retrieval technique and the Siepser/Chang modifed technique are demonstrated. A 10-O prolene with a long curved ctc-6 needle is u...sed to place a suture through the iris and under an 3 piece IOL haptic. Using the standard technique the two ends of the suture are retrieved through a common paracentesis near the fixation site and tied externally. The other haptic is tied using the Siepser sliding knot technique as described by Chang for this indication with an internal knot. The standard technique is a bit easier but does not allow as thight a knot for fixation of the iris to the haptic.

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.
