I was diagnosed with MALS 3 years ago and had release of the ligament. Initially fine but symptoms recurred. A stent was placed and I have been fine since. Interesting though is the fact that 4 years prior to surgery there was an abnormal Doppler ultrasound that was not followed up with CT angio.
It can be difficult to sort out GI problems if there is more than one issue- I have IBS, post cholecystectomy syndrome, GERD, SIBO and nonspecific autoimmune disease after collagenous colitis I am so much better now after a few months treatment with immunosuppressives. I also have learned to manage SIBO and GERD.
