Episcleral osseous choristomas arc rare, whitish, peaÂ sized, raised lesions that are typically found 5 to 10 mm posterior to the limbus. For this reason, radiographic imaging to assess adheÂ sions prior to surgical removal is recommended.

Surgical procedures that create stomas begin with a prefix denoting the organ, or area, being operated on and end with the suffix â-ostomyâ. Pre-operatively, the stoma site is marked on the skin whilst the patient is standing and sitting. The selected site should be away from the potential surgical incision, umbilicus and bony points. Intra-operatively, a stoma should be created without tension, with viable bowel and with an adequate vascular supply. Drainage can be established operatively be channelling the contents of the internal organs externally (i.

The union of two normally separate surfaces connected by fibrous connective tissue in an inflamed or damaged region. Adhesions may be classified into various types by virtue of whether they are early (fibrinous) or late (fibrous), or by underlying aetiology. Adhesions are the commonest cause of intestinal obstruction in the developed world and are responsible for 60â70% of small- bowel obstruction. In addition, adhesions are implicated as a cause of chronic pain and abdominal pain and secondary infertility.

Other hemispherotomy techniques have since been proposed order 250mg biaxin amex gastritis chronic symptoms, through a lateral peri-insular or transsylvian approach discount biaxin 250mg mastercard gastritis ulcer diet. The peri-insular hemispherotomy described by Villemure and Mascott  discount entocort 100 mcg with amex, which is derived from the concept of functional hem- ispherectomy, uses a small lateral supra- and infrainsular window through the frontoparietal and temporal opercula in order to reach the lateral ventricle. From here, resection of the amygdala and ante- rior hippocampus, as well as callosotomy and complete hemispher- ic disconnection, are performed. Afer resection of the anterior temporomesial structures and transsylvian exposition of the insular cortex, the lateral ventricle is accessed through the circular sulcus of the insula and a callosotomy and hemispheric disconnection can then be carried out. Shimizu and Maehara  have described another modifcation of the peri-insular hemispherotomy, beginning with a resection of the frontoparietal operculum and performing the diferent steps of complete hemispheric disconnection through this opercular resec- tion cavity. The lateral disconnection techniques are more difcult to per- form in pathologies with minimal cerebral atrophy or even hyper- trophic forms of cortical malformations, such as in hemimegalen- cephaly. In this pathology, the situation can be further complicated by a distorted anatomy of the lateral ventricle, the callosal body and other midline structures. The authors of the lateral approaches therefore recommend adapting the technique in these cases by en- larging the volume of excision, which also provides more space for postoperative brain swelling, which can particularly occur in hem- (b) imegalencephaly. Vertical parasagittal hemispherotomy Rasmussen: lateral (a) and axial (b) plane, demonstrating resection of the At our institution, hemispheric surgery for epilepsy has been temporal lobe, the central region and the insular cortex, with disconnection performed with one single technique, the vertical parasagittal of the remaining frontal and parieto-occipital lobes. To date, our personal experience with this technique amounts to more than 250 hemispherotomies over a period of 24 years. The distribution of the diferent underlying pathologies in our population is listed in Table 69. We have re- ported the surgical technique in detail, as well as the postoperative based on the idea that removal of the entire epileptogenic cortex results for a part of our patient population . Trough a small of SturgeâWeber syndrome, the cortical removal would include all parasagittal frontoparietal craniotomy, a limited cortical resection areas with pial angiomatosis, but could spare cortical regions not af- of approximately 3 cm Ă 2 cm is performed and pursued, until the fected, as is frequently seen in temporomesial cortex.
