Women giving birth at advanced reproductive ages in natural fertility conditions have been shown to have superior postmenopausal longevity. It is unknown whether improved survival is more likely among relatives of late-fertile women. This study compares survival past age 50 of men with and without a late-fertile sister in two populations: Utahns born in 1800-1869 identified from the Utah Popula...

et strictement positive : x 6= 0⇒ 〈x | x〉 > 0 (4) Finalement, H, muni de la norme ‖x‖ := 〈x | x〉 doit être un espace de Banach, i.e., être complet. La condition (3) est équivalente à 〈x | x〉 ∈ R, en effet 4〈x | y〉 = 〈x+ y | x+ y〉 − 〈x− y | x− y〉 + i〈x+ iy | x+ iy〉 − i〈x− iy | x− iy〉. L’équation (3) est donc conséquence de (4). Venons-en à la norme ; le point de départ est l’inégalité de Cauchy-...

INTRODUCTION Single anastomosis gastric bypass (one anastomosis gastric bypass or mini-gastric bypass) has been presented as an option of surgical treatment for obese patients in order to reduce operation time and avoiding eventual postoperative complications after Roux-en-Y gastric bypass.The main late complication could be related to bile reflux. AIM To report the experiences published afte...

BACKGROUND Since January 1 2005, the outcomes of bariatric surgeries have been recorded in Germany. All data are registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at Otto-von-Guericke University Magdeburg. METHODS Data are collected in an online data bank. Data collection began in 2005 for the results of Roux-en-Y-Gastric Bypass (RYGB). In addition to ...

OBJECTIVE Pancreaticoduodenectomy is a surgical procedure which is commonly accepted in cases of ampulla of Vater, head of pancreas, distal common bile duct neoplasms and severe chronic pancreatitis. Pancreatic fistula is still a serious problem after reconstruction. Yet, there is no consensus on a single reconstruction method. MATERIAL AND METHODS The reconstruction methods on patients who h...

Double-balloon endoscopy facilitates endoscopic retrograde cholangiopancreatography (ERCP) in patients with a Roux-en-Y anastomosis [1]. However, it is difficult to identify the afferent limb during double-balloon ERCP [2]. According to retrospective data from February 2007 to January 2009, the rate of accurate identification was 50% (14/28). We report a useful technique to identify the afferen...

PURPOSE The Roux en Y method has rarely been performed due to longer operation time and high risk of complication, despite several merits including prevention of bile reflux. We conducted a retrospective review of the result of Roux en Y reconstruction using two circular staplers after subtotal gastrectomy. MATERIALS AND METHODS From December 2008 to May 2009, a total of 26 patients underwent...
