Pancreaticoduodenectomy for pancreatic adenocarcinoma in a patient with situs inversus abdomenalis, a case report

INTRODUCTION AND IMPORTANCE: Situs Inversus (SI) is a rare congenital condition in which the abdominal and thoracic organs are located in a mirror image of the normal position in the sagittal plane. Although this condition does not affect normal health or longevity, its recognition is very important for treating many diseases, particularly those requiring surgical intervention. The relationship between situs inversus and cancer remain inconspicuous. CASE PRESENTATION: We report a 64-year old male with Situs Iinversus Abdominalis with Pancreatic Adenocarcinoma. Radiographic modalities were very important in preoperative assessment of the patient. The patient was managed by pyloric preserving pancreaticoduodenectomy. The patient received adjuvant chemotherapy and free of recurrence for one year after operation. CONCLUSION: Surgeons must recognize the complexity of operative intervention with respect to aberrant anatomy. The occurrence of Situs Inversus in a patient with pancreatic cancer must not deter the surgeon from sound oncologic principles of pancreatic surgery. Referral to these cases to tertiary level center is of utmost importance.
