**5. Aspiration therapy**

Nyström et al. [26] reported 2018 in a 4-year analysis on the results of the AspireAssist® system in 201 bariatric patients, including in particular class 2 and 3 obese patients. Using a modified PEG, patients can drain the food pulp and rinse with water 20 minutes after ingestion. This device could reduce the absorption of up to 30% ingested calories after a meal.

Results: EWL and TWL rates of 43.6% and 17.1%respectively were achieved after one year.

Complications: The complication rate corresponds to that of PEG (inflammation of the injection site, peritonitis, buried bumper).
