Short- and long-term outcomes after pancreaticoduodenectomy following total gastorectomy: Report of case series and literature review

Purpose Pancreaticoduodenectomy (PD) following gastrectomy (TG) should be considered challenging even currently although its procedure and clinical value have been being standardized. Short- and long-term outcomes as well as standard reconstruction method following these procedures remain unclear. In order to clarify these issues, we reviewed worldwide English literature and 4 of our own cases of PD for patients with previous TG. Methods Clinicopathological variables of 11 cases of PD for patients with previous TG were evaluated. Seven of these 11 were abstracted from a review of worldwide English literature and 4 of 11 were our own cases. Results 3 cases was reconstructed using Y-limb made in previous TG and afferent loop syndrome (ALS) was observed in 2 of 3, in these cases whereas no cases of ALS were found in cases reconstructed using newly-made Y-limb. In cases where PD was indicated for cancer, early cancer death, defined as death related to cancer recurrence observed within 2 years after PD, was observed in 6 of 9 cases. Notably in cases of pancreatic cancer recurrent cancer was diagnosed within 1 year after PD in 5 of 7 cases and 4 of these patients died of pancreatic cancer soon after recurrence. Conclusion In cases of PD following TG, previously-made Y-limb should not be used for reconstruction following PD because of probable cause of previously-made Y-limb for ALS. Long-term outcomes of PD after TG seemed unsatisfactory notably in cases of pancreatic cancer and thus application of PD for patients with previous TG should be carefully decided until reasonable explanation for this dismal outcome is obtained.
