A congenital choledochal cyst presented as an upper abdominal mass in a non-jaundiced woman; at laparotomy total cystectomy was performed and biliary enteric continuity re-established by a hepaticojejunostomy Roux-en-Y anastomosis.

Alchemical theory is emerging as a promising tool in the context of molecular dynamics simulations for drug discovery projects. In this theoretical contribution, I revisit the statistical mechanics foundation of non covalent interactions in drug-receptor systems, providing a unifying treatment that encompasses the most important variants in the alchemical approaches, from the seminal Double Ann...

Debate continues as to what type of reconstruction, after Total Gastrectomy, might be considered next to perfect. A retrospective analysis of 118 of these operations is carried out by the Author, comparing the experience obtained with 79 reconstructions by a newly developed technique (LYGIDAKIS method), 12 L.AWRENCE’s pouches, 12 Roux-en-Y esophagojejunostomies, 10 end-to-side esophagojejunosto...

INTRODUCTION Nutrition counseling is important for veterans undergoing gastric bypass surgery. The aim of this study was to explore the relationship between the number of nutrition visits a patient attended and change in body mass index (BMI) after gastric bypass surgery for the veteran population. METHODS A retrospective study examined veterans (N = 79) who underwent Roux-en-Y gastric bypass...

Afferent loop obstruction caused by enterolith formation is rare and cannot be easily treated with endoscopy because of the difficulty associated with the nonsurgical removal of enteroliths. A 74-year-old woman was admitted with fever and acute abdominal pain. Clinical features and imaging studies suggested afferent loop obstruction caused by an enterolith after Roux-en-Y hepaticojejunostomy. P...

Le Roux and Ziegler asked whether every simply connected compact nonempty planar Π 1 set always contains a computable point. In this paper, we solve the problem of le Roux and Ziegler by showing that there exists a planar Π 1 dendroid without computable points. We also provide several pathological examples of tree-like Π 1 continua fulfilling certain global incomputability properties: there is ...

Eighteen patients with dyspepsia and vomiting which followed surgery for peptic ulcer have completed a study to examine the role of diverting bile from the stomach by a Roux-en-Y procedure. Bile regurgitation and mild epigastric pain relieved by vomiting were abolished. Measurements of bile acids in the fasting gastric aspirate were useful in predicting the outcome of surgery; good results were...
