Is ok to have the ds 4 years later after the gastric sleeve?

The DS is the ideal operation if your weight loss after sleeve as been inadequate or if the weight has come back. I usually require patients to wait at least one year before doing the duodenal switch. Waiting longer will not have any affect. I have converted gastric bypasses 10+ years post op to duodenal switch and had fabulous outcomes. hope this helps. 

Hello, 
Yes! It is perfectly adequate  to consider a revision from the sleeve to a DS 4 years out if you did not lose enough weight and/or are regaining.   Your surgeon may decide to redo your sleeve too. We perform a barium swallow x ray to check the sleeve as part of the pre op tests and decide if a resleeve is needed to optimize results. 

DS is a good option for inadequate weight loss or weight regain after gastric sleeve.  I only offer this option in highly compliant patients as the consequences of non-compliance after the DS is severe vitamin/mineral deficienies that can lead to permanent disabilities.  There is a lot of upkeep with the DS so you need to really do your research before making this decision.  
Good luck!
