Aspiration treatment with AspireAssist™ empties food from the stomach after every meal to lose weight. Using a valve mechanism and associated tubing set and water reservoir the individual empties out digesta in the toilet 20 minutes after each meal and loses approximately 30% of the caloric intake in the diet. A 1 -year study in Karlskrona, Sweden, has shown a significant reduction in weight, almost 40% Excess Weight Loss (% EWL) reduction and median weight reduction of 16.5 kg after 6 months. For GBP the weight reduction of 1 year is in the order of 70-85 %. During 1 year of treatment with AspireAssist™ there were no serious complications or problems with the body's electrolyte balance noted either at the surgery or during follow-up. The advantage of this method is that it is completely reversible and the individual who does not wish to continue aspiration may have the tube into the stomach removed. GBP results in most of the stomach becoming disconnected and not accessible for the diagnosis of, for example, ulcers, bleeding, tumors or gall stones. AspireAssist™ does not have any lasting changes in the anatomy and thus will not lead to the potential for internal hernia that GBP unfortunately can cause. Wound infection occurs in approximately 9 % of cases when PEG tubes are placed in patients with cancer or stroke. Wound infections are, in most cases, treatable with antibiotics in tablet form and are very rarely considered to be a serious complication. Antibiotics are routinely given in conjunction with PEG insertion. Very unusual complication is leakage associated with insertion of the PEG and the method has been reported to have a risk of about 2 % during PEG insertion.
