Sleeve gastrectomy as revisional procedure for failed gastric banding or gastroplasty.

Background: Laparoscopic sleeve gastrectomy (LSG) is considered an effective multipurpose operation for morbid obesity, although long-term results are still lacking. Also, the best procedure to be offered in the case of failed restrictive procedures is still debated. We here reported our results of LSG as a revisional procedure for inadequate weight loss and/or complications after adjustable gastric banding or gastroplasty.

Laparoscopic gastric rebanding for slippage with pouch dilation: results on 29 consecutive patients.

Background: Laparoscopic adjustable gastric banding (LAGB) slippage with pouch dilation is one the most serious long-term complications and requires reoperation in most cases. It is still controversial whether banding should be offered again or a different procedure should be chosen. We report the results of synchronous de-rebanding on a prospective series of patients treated at our institution for slippage with pouch dilation.

Wernicke's encephalopathy during parenteral nutrition.

Background: Thiamine deficiency in humans affects the cardiovascular, muscular, nervous, and gastrointestinal systems. Wernicke's encephalopathy is described in alcoholism, in hyperemesis gravidarum, and in prolonged IV feeding without vitamin supplementation.

Methods: We report a case of a 66-year-old man undergoing surgery for acute necrotic-hemorrhagic pancreatitis, who presented a Wernicke's syndrome during parenteral nutrition (PN).
