BACKGROUND: Indications for distal pancreatectomy with en-bloc celiac axis resection (DP-CAR) in pancreatic carcinoma remain controversial. METHODS: Fifty-two consecutive patients with pancreatic cancer who underwent distal pancreatectomy, including 36 standard distal pancreatectomies (standard DP) and 16 DP-CAR were reviewed retrospectively. RESULTS: After standard DP, microscopically positive margins were identified at the dissection sites around the transection margins of the splenic arteries and were detected more frequently in the patients with tumors within 10 mm from the root of the splenic artery (14%). After DP-CAR, the estimated overall survival rate in patients who were pathologically negative for portal venous and artery invasion (n = 7) was greater than that of the other patients (n = 9; P = .023, log-rank test). The estimated overall 1- and 2-year survival rates after standard DP/DP-CAR were 81/81% and 52/53%, and the median survival times were 32/25 months, respectively, with no differences noted between the groups. There were no differences in the mortality rates and the incidence of each complication between the 2 groups except for delayed gastric emptying. CONCLUSION: DP-CAR was a feasible and safe procedure, similar to standard DP. DP-CAR should be reserved for patients without tumor infiltrating either the portal venous or arterial systems.
