Abstract Background: End-to-side esophagojejunostomy has almost always been associated with some degree of dysphagia. To overcome this complication we decided to perform an end-to-end anastomosis and compare it with end-to-side Roux-en-Y esophagojejunostomy. Methods: In this prospective study, between 1998 and 2005, 71 patients with a diagnosis of gastric adenocarcinoma underwent total gastrec...
UNLABELLED This study described and validated a new solid-state single-photon gamma-camera and compared it with a conventional-SPECT Anger camera. The compact new camera uses a unique method for localizing gamma-photon information with a bank of 9 solid-state detector columns with tungsten collimators that rotate independently. METHODS Several phantom studies were performed comparing the new ...
Fluid management during critical illness is a dynamic process that may be conceptualized as occurring in four phases: rescue, optimization, stabilization, and de-escalation (mobilization). The selection and administration of resuscitation fluids is one component of this complex physiological sequence directed at restoring depleted intravascular volume. Presently, the selection of i.v. fluid is ...
In this study, a non-linear mathematical model is proposed to solve the stochastic cellular manufacturing system (CMS) design problem. The problem is observed in both machine and labor-intensive cells, where operation times are probabilistic in addition to uncertain customer demand. We assume that processing times and customer demand are normally distributed. The objective is to design a CMS wi...
