A laparoscopic pancreaticoduodenectomy for pancreatic adenocarcinoma in a patient with situs inversus totalis.

Situs inversus totalis (SIT) is a congenital disorder in which the thoracic and abdominal viscera organs are mirrored from their normal anatomical position. Thus, the presence of any cancerous mass in one of the visceral organs of patients with SIT represents a great challenge due to the anatomical variation. We report a 52-year-old male with SIT who presented with obstructive jaundice and pancreatic-head mass. After preoperative examinations, it was decided to perform a laparoscopic pancreaticoduodenectomy. In this case, we aim to demonstrate the diagnosis and management of pancreatic cancer in an SIT patient, in addition to presenting the advantages and difficulties of laparoscopic surgery in this case.
