ObjectiveHigh-quality data indicating the advantages of preoperative Helicobacter pylori screening and eradication as well the clinical outcomes of patients with and without H. pylori after bariatric surgery are lacking.MethodsIn total, 96 morbidly obese patients with H. pylori preparing for bariatric surgery were retrospectively reviewed.ResultsOf 96 biopsy specimens, 73 (76%) were positive for H. pylori on initial Giemsa staining. These patients were treated with the standard 7-day antibiotic treatment protocol corrected by the individual patient’s creatinine clearance rate and body mass index and received a 30% higher dose because of their H. pylori positivity. A linear correlation was found between the effective antibiotic dose and the BMI with a recurrence rate of only 2.1% (2/96 patients). The preoperative percent estimated weight loss before surgery (17%) and in the first year of follow-up (68%–88%) was statistically equal between H. pylori-positive and -negative patients. Two early postoperative infectious complications and two postoperative surgical complications occurred in the preoperatively H. pylori-positive patients.ConclusionsA patient-tailored H. pylori eradication protocol prior to bariatric surgery is mandatory to improve the eradication rate and reduce the incidence of postoperative complications in mostly asymptomatic H. pylori-positive bariatric candidates.

Introduction: Physical activity (PA), exercise, and lifestyle intervention are basic interventions to reduce short- and long-term surgical and non-surgical complications in bariatric patients. The purpose of our study was, first, to evaluate the importance of individualized, professionally guided training, encouraging PA, and subsequent positive effects of physical ability and body composition following a structured and supervised exercise program. Methods: A total of 11 morbidly obese male (n = 4) and female (n = 7), aged 30–54 years, previously subjected to bariatric surgery, were recruited and subjected to 10-weeks structured and supervised exercise protocol with nutritional counseling and motivational support, consisting of twice weekly aquatic and outdoors training sessions. The same protocol was applied to the control group but without supervision, counseling and support. Blood analyses, basic anthropometric measures, body composition analyses, and physical fitness tests were performed before and after the exercise protocol. Results: The weight, body fat, BMI, systolic and diastolic pressures were mildly decreased after the exercise program, while sit-to-stand, handgrip, and one leg stance scores showed mild increase after the exercise program. Conclusion: Obese bariatric surgery patients may benefit from structured, supervised exercise program with nutritional counseling and motivational support. Further studies with larger number of participants are needed to confirm the results.
