I had an RNY bypass in 2016 The first came the stricture. The stomach to intestine opening kept closing up. After six balloon endoscopes, the dr decided to install a stent for six weeks to keep that opening open. The stent broke loose and migrated into intestines. Two surgeries to get it out and intestines got perforated. Another to fix. Then the infection then the adhesions started. Three more surgeries the worst was when the adhesions were so dense that the appendix and illeocecal valve had to be removed However, I’m still here to write this so thank god for modern medicine
Adhesions are always a risk with abdominal surgery but most people never get such severe complications
