Gastric bypass and sleeve gastrectomy: the same impact on IL-6 and TNF-α. Prospective clinical trial.

Background: Due to the association between the quantity of adipose tissue and concentrations of interleukin-6 (IL-6) and tumor necrosis factor (TNF-α), this work aimed to assess the effects of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) procedures on serum IL-6 and TNF-α concentrations.

Methods: This study evaluated serum IL-6 and TNF-α levels, as well as routine anthropometric and biochemical values, before and 1 year post-bariatric surgery. Fifty percent of patients (n = 24) underwent RYGB, and 50 % (n = 24) underwent SG.

Fuzzy obesity index (MAFOI) for obesity evaluation and bariatric surgery indication.

Background: The Miyahira-Araujo Fuzzy Obesity Index (MAFOI) for being used as an alternative in bariatric surgery indication (BSI) is validated in this paper. The search for a more accurate method to evaluate obesity and to indicate a better treatment is important in the world health context. Body mass index (BMI) is considered the main criteria for obesity treatment and BSI.

Veress needle insertion into the left hypochondrium for creation of pneumoperitoneum: diagnostic value of tests to determine the position of the needle in unselected patients.

Objective: To assess the effectiveness of the Veress needle puncture in the left hypochondrium and the accuracy of the tests described for the intraperitoneal correct positioning of the tip of the Veress needle in an unselected population.

Methods: Ninetyone patients consecutively scheduled for Videolaparoscopy had the abdominal wall punctured in the left hypochondrium. There were no exclusion criteria.

Erosive esophagitis after bariatric surgery: banded vertical gastrectomy versus banded Roux-en-Y gastric bypass.

Background: Obesity is associated with gastroesophageal reflux disease. Roux-en-Y gastric bypass is the most performed bariatric procedure in the world, whereas sleeve gastrectomy is an emerging procedure. Both can be combined with the use of a Silastic® ring.

Protective effect of carbon dioxide against bacterial peritonitis induced in rats.

Background: Carbon dioxide (CO(2)) has been used in the food industry as an antimicrobial agent. This study aimed to investigate whether CO(2) pneumoperitoneum might act similarly as an antimicrobial agent in the infected peritoneal cavity.

Methods: Peritonitis was induced in 58 rats by intraabdominal injection of an Escherichia coli inoculum (6 x 105 colony-forming units [CFU]/ml).

Creation of pneumoperitoneum: noninvasive monitoring of clinical effects of elevated intraperitoneal pressure for the insertion of the first trocar.

Aim: The aim of this work is to analyze, by means of noninvasive monitoring, the clinical effects of high intraperitoneal pressure for enough time to insert the first trocar.

Methods: Sixty-seven patients without significant lung problems were randomly divided into groups P12 (n = 30, maximum intraperitoneal pressure 12 mmHg) and P20 (n = 37, maximum intraperitoneal pressure 20 mmHg). A Veress needle was inserted into the left hypochondrium for creation of pneumoperitoneum.

Glucose homeostasis and weight loss in morbidly obese patients undergoing banded sleeve gastrectomy: a prospective clinical study.

Objective: To assess glucose homeostasis and weight loss in morbidly obese patients undergoing Silastic(R) ring sleeve gas-trectomy.

Methods: This was a prospective clinical study. Thirty-three female patients with a mean body mass index (BMI) of 42.

Silicone-ring Roux-en-Y gastric bypass in the treatment of obesity: effects of laparoscopic versus laparotomic surgery on respiration.

Background: The objective of this study was to compare the effects of silicone-ring Roux-en-Y gastric bypass carried out by laparoscopy versus that accomplished by laparotomy on pulmonary function.

Methods: A total of 26 women (body mass index (BMI) 35-49 kg/m(2)) were studied candidates for silicone-ring Roux-en-Y gastric bypass carried out by laparoscopy (LG; n = 13) and laparotomy (or open surgery (OG); n = 13). Smokers, patients having lung disease, and those unable to carry out the tests properly were excluded.

Injuries caused by Veress needle insertion for creation of pneumoperitoneum: a systematic literature review.

Background: The aim of this study was to assess the prevalence, risks, and outcomes of injuries caused by the Veress needle described in the literature.

Methods: Iatrogenic injuries caused by Veress needle insertion during diagnostic or therapeutic laparoscopies in humans were researched, with no language restriction, in the Medline, Lilacs, Embase, Scielo, and Cochrane Library databases. The following words were combined: "Veress" or "insufflation needle" or "pneumoperitoneum needle," and "complications" or "injuries" or "lesions.

Comparative study of hand sewn single layer anastomosis of dog's bowel.

Background: Two-layer intestinal anastomosis increases the inflammatory response while single-layer anastomosis results in a better wound healing. However the four main kinds of stitches which may be chosen in performing single layer intestinal sutures never before had been comparatively studied.

Aim: To compare the four more commonly used types of single layer surgical anastomosis sutures of the digestive tract.

The impact of obesity on pulmonary function in adult women.

Introduction: Obesity can cause deleterious effects on respiratory function and impair health and quality of life.

Objective: To evaluate the effects of obesity on the pulmonary function of adult women.

Methods: An obese group, constituted of 20 women between 20 and 35 years old with a BMI of 35 - 49.

[Evaluation of tests performed to confirm the position of the Veress needle for creation of pneumoperitoneum in selected patients: a prospective clinical trial].

Purpose: To evaluate tests performed to confirm the position of the Veress needle inserted into the left hypochondrium for creation of pneumoperitonium.

Methods: One hundred patients were submitted to laparoscopic procedure with left hypochondrium puncturing. Needle positioning tests were evaluated.

Veress needle insertion in the left hypochondrium in creation of the pneumoperitoneum.

Purpose: To test the efficacy of the puncture in the left hypochondrium as an alternative method.

Methods: Sixty-two patients randomly distributed into two groups were studied: Group LH, puncture in the left hypochondrium (n=30), and Group ML, puncture in the abdominal midline (n=32). The following were assessed: needle positioning tests, number of failed attempts at needle insertion, and time needed for creation of pneumoperitoneum.

Evaluation of the positioning of the tip of the Veress needle during creation of closed pneumoperitoneum in pigs.

Purpose: Erroneous punctures and insufflations are frequent with the use of the Veress needle. Mistaken injections of gas in the preperitoneal space are not rare. The purpose of this research is to evaluate the correct positioning of the tip of the needle during creation of pneumoperitoneum.

[One layer sutures of digestive tract knotted in the lumen, in dogs: perforating stitch versus serosubmucosal suture].

Objective: To compare hand sewn digestive tract single layer anastomosis with knots tied in the lumen: total stitches versus serosubmucosal.

Methods: Six mongrel dogs were submitted to laparotomy, each one with two transversal jejunum sections, 30 and 70 cm far from Treizt angle and suture, serosubmucosal and total stitches, both with knots tied in the lumen, over the mucosa, at the posterior wall. After slaughter (7th post-operative day) was evaluated the peritoneal adhesions at posterior wall.
