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.

Radiologic and endoscopic characteristics of laparoscopic antireflux wrap: correlation with outcome.

After antireflux surgery for gastroesophageal reflux disease, 10% to 15% of patients may have unsuccessful results as a result of abnormal restoration of the esophagogastric junction. The purpose of this study was to evaluate the postoperative endoscopic and radiologic characteristics of the antireflux barrier and their correlation with the postoperative results. After surgery, endoscopic and radiologic features of the antireflux wrap were evaluated in 120 consecutive patients.

Type 2 diabetes mellitus in patients with mild obesity: preliminary results of surgical treatment.

In the last years, type 2 diabetes mellitus (T2DM) and obesity have become a serious public health problem, behaving as epidemic diseases. There is great interest in exploring different options for the treatment of T2DM in nonmorbidly obese patients. The purpose of this study is to report parameters of glycemic control in patients with T2DM and mild obesity who underwent laparoscopic Roux-en-Y gastric bypass (RYGBP).

Classification and management of leaks after gastric bypass for patients with morbid obesity: a prospective study of 60 patients.

The most important and frequent major complication after gastric bypass is the appearance of a leak, which can result in death of a patient. The purpose of this prospective study was to determine the incidence of a postoperative leak, to propose a classification and to evaluate the results of conservative or surgical treatment. All patients submitted to gastric bypass either laparotomic or laparoscopic were included in a prospective protocol.

Incidence of marginal ulcer 1 month and 1 to 2 years after gastric bypass: a prospective consecutive endoscopic evaluation of 442 patients with morbid obesity.

Methods: Photographic results of full-face carbon dioxide laser resurfacing were evaluated after 1, 5, and 10 years. Statistical analysis considered surgeon and patient satisfaction based on a predetermined cosmetic visual analogue scale.

Laparoscopic sleeve gastrectomy: surgical technique, indications and clinical results.

Background: Laparoscopic sleeve gastrectomy (LSG) has been introduced as a multipurpose restrictive procedure for obese patients. Variations of the surgical technique may be important for the late results.

Methods: 50 patients submitted to LSG from January 2005 to December 2006 were studied.

A new technique of "double-A" bilateral flaps based on perforators for the treatment of sacral defects.

Background: Myocutaneous and fasciocutaneous flaps can provide stable coverage of sacral defects. For neurologically intact patients, sensate innervated gluteal artery perforator flaps are the ideal solution. For patients with spinal cord injury, soft-tissue coverage can be performed with a variety of noninnervated flaps.

Nonresective shrinkage of the septum and fat compartments of the upper and lower eyelids: a comparative study with carbon dioxide laser and Colorado needle.

Background: The purpose of this article is to describe an alternative nonresective treatment of the fat-septum component of the eyelids during blepharoplasty, using shrinkage desiccation with two low-energy modalities: a carbon dioxide laser and a low-range grid of electrocautery with a Colorado microdissection needle.

Methods: Thirty-six patients underwent a four-lid blepharoplasty. During surgery, after exposure (not opening) of the septum and assessment of the amount of bulging by gentle globe compression, a grid spray of electrocautery (right eye) and carbon dioxide laser (left eye) was applied over the entire septum until shrinkage and correction of the bulging was achieved.

A clinical retrospective study comparing two short-scar face lifts: minimal access cranial suspension versus lateral SMASectomy.

Background: The purpose of this study was to retrospectively compare the short- and long-term cosmetic outcomes of two minimal incision rhytidectomies and analyze their advantages and disadvantages.

Methods: The results of minimal access cranial suspension face lift versus minimal incision rhytidectomy with lateral SMASectomy were evaluated after 1 and 24 months. Statistical analysis considered surgeon/patient satisfaction, time used in the procedures, pain, and learning curves.

Geometric analysis of the V-Y advancement flap and its clinical applications.

Background: Geometry is fundamental in the comprehension of local flap design. The purpose of this study was to discuss the differences between the V-Y advancement flap and other local flaps, understand its geometry, and analyze its clinical applications.

Methods: The analysis was based on qualitative measurements of an injury, taking into consideration the following dimensions: largest diameter, shortest diameter, and depth.

Mortality trends from burn injuries in Chile: 1954-1999.

Objectives: To study mortality trends due to burns in Chile.

Methods: Correlation, and descriptive study. Death reports from the Annals of Demography from 1954 to 1999, were analyzed and standardized rates of mortality by etiology, age and sex were calculated using regression models (Prais-Winsten) for each of them.

Effect of duodenal diversion on low-grade dysplasia in patients with Barrett's esophagus: analysis of 37 patients.

It is well known that in patients with Barrett's esophagus (BE), even after antireflux surgery, intestinal metaplasia can progress to dysplasia or even adenocarcinoma. However, the opposite-that is regression of dysplastic changes to intestinal metaplasia after antireflux surgery-has been documented in only a few reports. The objective of this study was to determine the effect of a duodenal diversion operation on low-grade dysplasia in patients with BE.
