Clinical study on distal pancreatectomy with en bloc celiac axis resection with analysis of vascular variation

Objective: To analyze the short-term efficacy of distal pancreatectomy with en bloc celiac axis resection (DP-CAR) in the treatment of locally advanced pancreatic body or tail cancer and the effect of vascular variation on morbidity after DP-CAR. Methods: A retrospective study was undertaken of 43 cases with pancreatic ductal adenocarcinoma diagnosed by pathological examination in the treatment of DP-CAR. R0 resection, morbidity and mortality were analyzed perioperatively with the effect of vascular variation. Results: R0 resection by DP-CAR was 81.4% in this study with mortality 7.0% and morbidity 45.6%. Eight cases were found with vascular variation. The postoperative morbidity in the group with vascular variation and in the group without vascular variation was 3/8 (37.5%) vs 17/35 (48.5%) and the mortality 1/8 (12.5%) vs 2/35 (5.7%), respectively. There was no significant difference statistically in morbidity and mortality between 2 groups. Conclusions: DP-CAR has the advantage of safety and feasibility. There would be no effect of vascular variation on morbidity after DP-CAR.
