Although the complications of this surgery have decreased with the advancement of medicine and post-treatment care, there are still complications that can lead to death if neglected. In this case report, we present a 44-year-old patient who underwent redo bariatric surgery. She was discharged from the hospital in good general condition but returned a few days later with a major complaint of abdominal pain and sudden bleeding from the upper gastrointestinal tract. After performing CT and endoscopy and considering the results. the patient underwent laparotomy, which showed a fistula between the splenic artery and the remnant of the stomach. After surgery and after the recovery period, the patient was discharged from the hospital.

We suggest that a fistula between the splenic artery and the remnant of the stomach should be considered in patients with abdominal pain and upper gastrointestinal bleeding who underwent redo bariatric surgery.
