Tolerance and efficacy of an air-filled balloon in non-morbidly obese patients: results of a prospective multicenter study.

Background: Intragastric balloons have been proposed to induce body weight loss in obese subjects. Most studies were performed using liquid-filled balloons. Air-filled balloons may increase digestive tolerance.

Effects of intragastric balloon on gastric emptying and plasma ghrelin levels in non-morbid obese patients.

Background: Intragastric balloons have been proposed to induce weight loss in obese subjects. The consequences of the balloon on gastric physiology remain poorly studied. We studied the influence of an intragastric balloon on gastric emptying and ghrelin secretion in non-morbid obese patients.

Randomized trial of a low-molecular-weight heparin (Kabi 2165) versus adjusted-dose subcutaneous standard heparin in the prophylaxis of deep-vein thrombosis after elective hip surgery.

124 patients undergoing total hip replacement were randomly allocated to receive Kabi 2165, 2,500 anti-Xa units twice a day (group A); Kabi 2165, 2,500 anti-Xa units twice a day during the first 48 h postoperatively and then 5,000 anti-Xa units once a day (group B), or adjusted-dose standard heparin, monitored by activated partial thromboplastin time (group C). The first dose was given 2 h before surgery in the three groups. Deep-vein thrombosis (DVT) was detected by radiolabelled fibrinogen uptake and bilateral venography was performed in patients who had a positive scan.
