The musculature of the ureter has a layered arrangement in which the internal layer is mainly longitudinal and the external layer is largely circular. There is, however, intermingling and migration of fascicles between layers. At the passage of the ureter through the bladder wall this layering is lost and all fascicles become oriented longitudinally. At the ureterovesical junction fibers of the...

conclusions cpaa provided not only better functional results than scaa, but also improved quality of life, thus may be the better choice. background the tendency towards sphincter preserving for low rectal cancers with low anterior resection, has led to the technique of straight coloanal anastomosis (scaa) or colonic j-pouch anal anastomosis (cpaa). objectives the aim of our study was to compar...

Introduction: Esophageal cancer is a common gastro intestinal malignancy. One of the most common techniques of surgery in esophageal cancer is transhiatal esophagectomy with esophagogastric anastomosis in the neck. This technique is accompanied by complications like chronic gastero-esophegeal reflux and late stenosis. This study was designed to compare the risk of complications after two surgic...

BACKGROUND AND PURPOSE Surgical stapling devices are often used to secure the distal ureter along with a cuff of bladder during laparoscopic nephroureterectomy. As the viability of cells within the stapled tissue would be important in patients with upper urinary-tract transitional-cell carcinoma, we determined the viability of cells within the lines of various commercially available staplers in...

background in this study, given the importance of gastrointestinal anastomosis in surgical procedures, attempts have been made to compare the results of employing magnetic compression anastomosis and magnetic coils in intestinal anastomosis of rats. materials and methods this study was an experimental trial on 60 rats which had been randomly divided into two experiment (30) and control (30) gro...

abstract   background : although, different studies on end-to-side nerve repair, results are controversial. the importance of this method in case is unavailability of proximal nerve. in this method, donor nerves also remain intact and without injury. in compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. overall, the previous studies in ...
