PurposeRisk factors of ischemic gastropathy (IG) following distal pancreatectomy with en bloc celiac axis resection (DP-CAR) remain unclear.MethodsFifty consecutive patients with pancreatic cancer who underwent DP-CAR were retrospectively reviewed for possible risk factors for IG. This study was registered on the UMIN Clinical Trials Registry (UMIN 000028732).ResultsComplications higher than grade 3 were observed in 21 patients (42%) and mortality in 4 (8%). Left gastric artery (LGA) resection (P = 0.046) and a combination of left inferior phrenic artery (IPA) with LGA resection (P = 0.012) were risk factors of IG, and an elevated creatine kinase (CK) value ≥ 1005 IU/L (P = 0.025) was associated with IG. Among prognostic factors, IG (OR, 5.997; 95% CI, 1.543–23.309; P = 0.010), completion of adjuvant chemotherapy (OR, 0.282; 95% CI, 0.121–0.654; P = 0.003), longer operative time (OR, 2.261; 95% CI, 1.084–4.714; P = 0.030), and higher age (OR, 2.212; 95% CI, 1.081–4.524; P = 0.030) remained independent predictors of survival. Comparison at 2 and 3 months postoperatively showed nutritional values were higher in patients who underwent LGA-preserving DP-CAR than those with LGA-resecting DP-CAR: total protein (7.17 ± 0.56 vs 6.65 ± 0.66 g/dl, P = 0.007), albumin (4.04 ± 0.45 vs 3.43 ± 0.43 g/dl, P < 0.001), and total cholesterol (162.3 ± 34.7 vs 141.6 ± 27.2 mg/dl, P = 0.044).ConclusionsThe poorer prognosis in patients who undergo DP-CAR may be related to more advanced tumors. A combination of left IPA and LGA resection was a significant risk factor for IG. IG, completion of adjuvant chemotherapy, longer operative time, and higher age remain good independent predictors of survival.
