N2 - Background: In recent years, the number of minimally invasive pancreatoduodenectomy (MIPD) has been increasing; however, the procedure has not been widely accepted due to its complexity and difficulty. We have developed a technique to mobilize the pancreas head using a left-sided approach with a focus on the complete dissection of the Treitz ligament. Methods: This technique focuses on the secure mobilization of the pancreas head using a left-sided approach. First, the transverse mesocolon is flipped upward and the anterior side of the mesojejunum is excised to expose the first jejunal artery (1st JA) from the distal side to its origin. During the procedure, the left sides of the SMA and Treitz ligament are exposed. The Treitz ligament is retracted to the left side and dissected anteriorly. Thereafter, the jejunum is flipped to the right side and the retroperitoneum around the origin of the jejunum and duodenum is dissected to identify the inferior vena cava (IVC). The rest of the Treitz ligament is dissected posteriorly and complete resection of the Treitz ligament releases the limitation of duodenal immobility. Thereafter, dissection proceeds along the anterior wall of the IVC, and mobilization of the pancreas head is completed from the left side. Results: A total of 75 consecutive patients underwent MIPD from April 2016 to July 2022. The median operation times of laparoscopic and robotic procedures were 528 min (356–757 min) and 739 min (492–998 min), respectively. The volume of blood loss during laparoscopic and robotic procedures was 415 g (60–4360 g) and 211 g (17–1950 g), respectively. There was no mortality in any of the cases. Conclusion: Mobilization of the pancreas head and left-sided approach using a caudal view will be a safe and useful technique for MIPD.
