ABSTRACT
INTRODUCTION AND IMPORTANCE: Obesity is a global epidemic, and bariatric surgery is an effective treatment. During this surgery, rare abnormalities in the small intestine, like ectopic pancreas (EP), can be found. CASE PRESENTATION: A 16-year-old male presented at the surgical clinic with a complaint of morbid obesity, weighing 140 KG. Since he was unable to commit to a diet, bariatric surgery was performed. During the surgery, the gastrointestinal tract was examined, and an incidental finding was noted in the wall of the proximal jejunum. The histopathology report revealed that the excisional biopsy was a complete EP in the proximal jejunum. The patient was discharged from the hospital on the first postoperative day, and his condition remained stable. CLINICAL DISCUSSION: Our case of EP stood out due to its larger size, measuring 3.5 cm in diameter, while EP lesions are typically smaller, despite its size, the patient did not experience any symptoms. EP is more commonly found in individuals between 40 and 50 years old, with a higher incidence in males. However, our patient is only 16 years old. CONCLUSION: Surgical resection is the most effective treatment, preventing malignant transformation and future complications. To the best of our knowledge, this is the first documented case of incidentally detected heterotopic pancreatic tissue in jejunum during a bariatric procedure in Syria, and it is also the fourth case in the medical literature.
