[Consensus statement of the Chilean endocrinological society on the role of bariatric surgery in type 2 diabetes].

Diabetes Mellitus (DM) and obesity are a public health problem in Chile. Bariatric surgery is the most effective treatment alternative to achieve a significant and sustained weight reduction in patients with morbid obesity. The results of controlled clinical trials indicate that, compared to medical treatment, surgery for obese patients with DM2 allows a better control of blood glucose and cardiovascular risk factors, reduces the need for medications and increases the likelihood for remission.

Is laparoscopic sleeve gastrectomy an acceptable primary bariatric procedure in obese patients? Early and 5-year postoperative results.

In this paper, we analyze and discuss the possibility of Laparoscopic sleeve gastrectomy being accepted as a primary and definitive procedure for obese patients with comorbidities. This is based on our postoperative and 5 years of follow-up result and comparing them with the data reported in the international literature. For comparison of the results, a narrative revision of the literature was performed, using the Medline, Pubmed, and data base publications (Medline, Lilacs, and Cochrane Library), looking for the term "Sleeve gastrectomy," "Obesity," "Bariatric surgery," "Laparoscopic surgery" including "Review" articles and also other 42 selected papers.

[Solid-pseudopapillary tumor of the pancreas. Presentation of 3 clinical cases].

The solid-pseudopapillary tumors of the pancreas (TSPP) are a uncommon neoplasm (1- 2% of exocrine tumors). Are more frequent in young women and presents a low malignant potential (15% develop metastases). Its preoperative diagnosis is very difficult, because these tumors haven`t radiological features that makes distinguish from the other pancreatic cysts tumors.

Distribution of urocanic acid isomers between aqueous solutions and n-octanol, liposomes or bovine serum albumin.

The distribution of urocanic acid (UCA) isomers between aqueous solutions and n-octanol, egg yolk phosphatidylcholine (eggPC) liposomes or bovine serum albumin (BSA) has been evaluated. Regarding its partitioning between water and n-octanol, the behaviour of both isomers is very similar, and the amount incorporated to the organic solvent is mostly determined by the fraction of the compound that, in the aqueous phase, is present as uncharged species. This implies that the highest hydrophobicity occurs near the isoelectric point.

[Nutcracker esophagus. Analysis of 80 patients].

Background: The nutcracker esophagus, a primary motor disorder, is frequently associated with noncardiac chest pain.

Aim: To study the clinical, endoscopic, manometric, and pathological features and 24 h acid reflux in patients with nutcracker esophagus.

Patients And Methods: Eighty patients (63 females, aged 26 to 70 years) with nutcracker esophagus, defined as the presence of contraction waves of more than 180 mmHg in the esophageal manometry, were studied.
