I had wls band to sleeve conversion on 4/24/17. On 7/5/17 I started having bilateral flank pain, no fever, with fatigue and severe epigastric pain. My surgeon increased my pantoprazole 40 mg to twice a day and ordered an upper gi X-ray. The upper GI X-ray looked fine. Flank pain, fatigue and nausea returned. They did a CT scan on 8/18. Some small non obstructive kidney stones were found as well as a seroma in my abdomen near the surgical site. Anyone else developed a seroma this far out from surgery?
