Setting: The study was conducted at the University Hospital, State University of Londrina, Brazil, which is a referral center for the treatment of obesity.

PREOPERATIVE MANOMETRY FOR THE SELECTION OF OBESE PEOPLE CANDIDATE TO SLEEVE GASTRECTOMY.

Background: Sleeve gastrectomy may alter esophageal motility and lower esophageal sphincter pressure.

Aim: To detect manometric changings in the esophagus and lower esophageal sphincter before and after sleeve gastrectomy in order to select patients who could develop postoperative esophageal motilitity disorders and lower esophageal sphincter pressure modifications.

Methods: Seventy-three patients were selected.

Roux-en-Y gastric bypass: limb length and weight loss.

Background: Roux-en-Y gastric bypass is a surgical technique widely used in the treatment of obesity. It is unclear, however, if the length of the biliopancreatic and alimentary limb interferes with the magnitude of weight loss.

Aim: To evaluate if the length of these limbs is related to the percentage of weight loss one year after surgery.

[Esophageal motility, symptoms, food intake and weight loss after Roux-en-Y gastric bypass].

Background: Abnormal manometry findings can be found in the obese population. It is controversial if the manometry should be used to choose the adequate operation or if the motility status could predict symptomatic outcomes.

Aim: To correlate the esophageal motility with postoperative symptoms, alimentary outcome and weight loss after Roux-en-Y gastric bypass.

Endoscopic findings of asymptomatic patients one year after Roux-en-Y gastric bypass for treatment of obesity.

Background: In the late post-operative period, the necessity of performing an upper gastrointestinal endoscopy (GIE) to check for complications is controversial. Some authors suggest it should be routine for all patients, others selectively, but not all patients with endoscopic abnormalities are symptomatic and some abnormalities are potentially severe. The study was conducted to evaluate the endoscopic findings from asymptomatic obese patients after Roux-en-Y gastric bypass (RYGB) and correlate them with the demographic data and the presence of Helicobacter pylori (Hp).

Weight loss outcome after Roux-en-Y gastric bypass: 10 years of follow-up.

Background: By submitting obese people to surgical treatment, we hope they lose weight and stay slim. Long-term monitoring is essential to assess effectiveness of surgery. This study aims to evaluate weight loss over 10 years in an obese population undergoing banded Roux-en-Y gastric bypass (B-RYGBP).

Urinary evaluation after RYGBP: a lithogenic profile with early postoperative increase in the incidence of urolithiasis.

Background: The objective of this study was to assess predictors for new-onset stone formers after Roux-en-Y gastric bypass (RYGBP).

Methods: One hundred and fifty-one obese patients underwent RYGBP and were followed for 1 year. The analysis comprised two study time points: preoperative (T0) and 1 year after surgery (T1).

Esophageal motility after laparoscopic Roux-en-Y gastric bypass: the manometry should be preoperative examination routine?

Background: Our goal was to identify the changes of esophageal motility, lower esophageal sphincter (LES) function, and eating adaptation before and after Roux-en-Y gastric bypass (RYGBP) and whether manometry should be a routine examination in patients who undergo this procedure.

Methods: A total of 81 patients underwent manometry before surgery and 1 year after surgery. The control group consisted of 10 nonobese volunteers.

Weight loss eight years after gastric bypass.

Objective: To evaluate the effectiveness of banded Roux-en-Y gastric bypass in promoting weight loss after an eight-year follow-up.

Methods: Two hundred and eleven obese patients underwent Roux-en-Y gastric bypass with banding by the same surgical team. The study design was longitudinal, prospective and descriptive.

Roux-en-Y gastric bypass and inflammatory activity of the adipose tissue.

Objective: To evaluate the oxidative stress and inflammatory markers in obese patients before and after Roux-en-Y vertical banded gastroplasty.

Methods: We studied 20 class III obese patients undergoing Roux-en-Y vertical banded gastroplasty, seven men and 13 women, mean age 39 years, and 20 non-obese subjects, nine males and 11 females, mean age 38 years. We determined the plasma levels of malondialdehyde, stress an index, total antioxidant capacity, catalase, reduced and oxidized glutathione and inflammatory markers (C reactive protein and á-1 acid glycoprotein).

Morphofunctional evaluation of the heart of obese patients before and after bariatric surgery.

Background: This study aims to evaluate the effect of weight loss on the physical capacity and the structure and function of the heart after bariatric surgery.

Methods: Forty-three adult obese patients, 31 women (72.1%) and 12 men (27.

Weight loss outcome after silastic ring Roux-en-Y gastric bypass: 8 years of follow-up.

Background: An underlying major aim of bariatric surgery is weight loss and its long-term maintenance. In spite of this, most studies regarding weight loss after surgical treatment of morbid obesity show 3-year follow-up results. We evaluated the effectiveness of silastic ring Roux-en-Y gastric bypass (SR-RYGBP) in promoting significant weight loss after an 8-year follow-up at the Londrina State University Hospital.

[Nutritional and metabolic evaluation of patients after one year of gastric bypass surgery].

Objective: To assess nutritional and metabolic evolution and inflammatory activity in severe obese patients submitted to bariatric surgery.

Methods: This prospective study evaluated 56 patients (50 female and 6 male), mean age 40 + or - 9,9 years, submitted to RYGB. Nutritional, metabolic, and inflammatory parameters were assessed prior to and 12 months postsurgery.

Influence of the actual diameter of the gastric pouch outlet in weight loss after silicon ring Roux-en-Y gastric bypass: an endoscopic study.

Some sort of restriction of the pouch emptying is supported by many surgeons to allow a sustained weight loss through the use of a ring placed circumferentially around the gastric pouch. Most previous studies focused on the length of the ring, not the actual diameter of the gastric pouch outlet. This study aims to evaluate the association between the actual diameter of the gastric pouch outlet and the weight loss in obese patients submitted to silicon ring Roux-en-Y gastric bypass.

Reduction in plasma levels of inflammatory and oxidative stress indicators after Roux-en-Y gastric bypass.

Background: Obesity is considered to be associated with high levels of oxidative stress and inflammation. Anticipated weight loss secondary to bariatric surgery may offer an opportunity to evaluate this association. We studied a few markers of oxidative stress and inflammation in 20 obese patients submitted to Roux-en-Y gastric bypass (RYGBP).

Weight loss outcome after silastic ring Roux-en-Y gastric bypass: five years of follow-up.

Background: An underlying major aim of bariatric surgery is weight loss and its long-term maintainance. In spite of this, most studies regarding weight loss after surgical treatment of morbid obesity, show 3-year follow-up results. We evaluated the effectiveness of Silastic ring Roux-en-Y gastric bypass (SR-RYGBP) in promoting significant weight loss after a 5-year follow-up at the Londrina State University Hospital.

Computerized baropodometry in obese patients.

Background: Few studies have investigated the influence of obesity on the structural and functional performance of the feet, and its potential implications for the musculoskeletal system. Computerized baropodometric analysis (CPA) is a new investigation for the center of pressure, plantar surface area and plantar pressure while standing on the platform of a specialized apparatus. CPA is relevant to gait and posture, and may be important as well for postoperative musculoskeletal disorders.

Rhabdomyolysis after bariatric surgery.

Background: Rhabdomyolysis is a potential threat after bariatric surgey. The severity ranges from asymptomatic elevations of serum muscle enzyme levels to life-threatening cases associated with muscle necrosis, compartment syndrome, acute renal failure and cardiac arrest.

Methods: We studied 98 consecutive obese patients who underwent primary uncomplicated bariatric surgery during a 1-year period.

Accuracy of magnetic resonance in identifying traumatic intraarticular knee lesions.

Purpose: To evaluate the diagnostic accuracy of magnetic resonance imaging of the knee in identifying traumatic intraarticular knee lesions.

Method: 300 patients with a clinical diagnosis of traumatic intraarticular knee lesions underwent prearthoscopic magnetic resonance imaging. The sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio for a positive test, likelihood ratio for a negative test, and accuracy of magnetic resonance imaging were calculated relative to the findings during arthroscopy in the studied structures of the knee (medial meniscus, lateral meniscus, anterior cruciate ligament, posterior cruciate ligament, and articular cartilage).

Gait cinematic analysis in morbidly obese patients.

Background: Functional co-morbidities of excess body weight such as gait problems are never life-threatening like those associated with certain metabolic sequelae. Nevertheless, they may interfere with quality of life and also act as a mirror of muscle, bone and joint stress. In this prospective study, the goal was to document dynamic aspects of gait in severely obese subjects.

Postural changes in morbidly obese patients.

Background: Postural deviations in morbidly obese individuals may contribute to low self-esteem and to long-term adverse effects on bones and joints. In a case-control study, the axial skeleton was investigated, to disclose the main abnormalities found in obese compared to non-obese groups.

Methods: 2 groups were compared.
