Hi everyone. I'm a bit of a complicated outlier, as my duodenal switch will be a modified duodenal switch with Demeester adjustment. I'm getting a duodenal switch for biliary diversion ( bile reflux). And I have a herniated stomach, so it will need a hernia repair. This means my stomach will not be reduced, but it will be restored in terms of hernia. And the new bile limb will only be around a 100 to a 150cm down. Enough to prevent bile from flowing into my stomach, but less malabsorption and weight loss issues. The issue is, that my stomach gas gastroptosis ( which means it is very elongated and stretched down towards my pelvis) this means it is quite painful and traumatic when vomiting occurs. I have read so many horror stories about vomiting post op or even within the first 3 to 6 months. I'm wondering, does that mainly occur due to reduction of the stomach? Or is it an unavoidable cause of the new limbs being created. I'm terrified of obstructions, ileus and other nasty complications.
