Complications in the form of pouch dilatation may occur in post-sleeve surgery. However, revision sleeve gastrectomy procedures are effective in correcting such complications. The aim of this study was to systematically review all published cases that reported revision surgeries following the initial sleeve gastrectomy complicated by pouch dilatation. In addition, we are presenting two cases reported from our military/teaching hospital. A systematic literature search was conducted from English-language studies published from 2000 to 2014 from the following databases: PubMed, CINAHL, MEDLINE, EMBASE, Clinical evidence, Dara, Scopus, Web of Sciences, TRIP, Health Technology Database, Cochrane library, and Psych INFO. A total of 5340 articles were identified in the initial search and 5339 articles were excluded based on the exclusion criteria. Only one case study met the inclusion criteria for this systematic review, involving two patients. Also, we are reporting two cases with revision surgery performed for pouch dilatation post-sleeve surgery from our teaching hospital.?There was only one study that reported revision surgery as a management of gastric pouch dilatation post-sleeve surgery. Authors believe that the incidence of revision surgery for the management of pouch dilatation post-sleeve surgery is higher but underreported. This assumption may be valuable, especially because some surgeons consider pouch dilatation post-sleeve surgery a complication that arises due to surgical technique rather than the procedure itself;therefore, it is unreported.展开更多

The technique is a simple self-adaptive all-optical system, which performs image processing and nonlinear optical measurements at the same time. Preferred spatial frequencies can be selected by shifting the nonlinear sample through the focus. Edge enhancement was demonstrated by filtering of low frequency with the nonlinear material at the Fourier plane.展开更多
