Safety and Feasibility of a Pancreaticoduodenectomy with Total Meso-Pancreatoduodenum Excision: Analysis in Various
Background/Aims:
This study aimed to evaluate the safety and feasibility of a pancreaticoduodenectomy with total meso-pancreatoduodenum excision (tMPDe) as an new anatomical concept.
Methodology:
A total of 90 patients underwent PD for various periampullary diseases. Of these, 52 patients received a conventional PD (cPD), while 38 patients underwent a tMPDe. Surgical outcomes were compared between the two study groups.
Results:
Operative time was equivalent in the two groups; however, the estimated blood loss (cPD, 1360 ml; tMPDe, 995 ml; median, P = 0.026) and blood transfusion rate (cPD, 63%; tMPDe, 31% ; P = 0.001) were significantly decreased in tMPDe. Morbidity had no significant difference between cPD and tMPDe, and tMPDe showed no characteristic complications. With regard to oncological aspects, tMPDe was superior to cPD. Risk factors analysis revealed the operative time (P = 0.003), estimated blood loss (P < 0.001), and blood transfusion (P < 0.001) to be significant predictive risk factors for postoperative morbidity but not tMPDe procedure (P = 0.794).
Conclusions:
tMPDe is safe and superior to cPD because it is a bloodless operation with a good oncological outcome: We concluded that tMPDe should be adaptable to various periampullary diseases, including benign and low-grade malignant disorders.
