Feasibility of preserving the remnant stomach during distal pancreatectomy after distal gastrectomy

Abstract
Purpose The safety and feasibility of preserving the remnant stomach during distal pancreatectomy (DP) in patients who have undergone distal gastrectomy (DG) remains unclear. Methods A retrospective review of a prospectively maintained database was performed to identify patients who underwent DP. A propensity score-matched analysis was performed to match post-DG patients with control patients. Results Among the 226 patients included in this study, 9 DP patients who had a history of DG were studied (4.0%). These nine patients in the DG group were matched to 45 patients in the control group. There were no significant differences in the incidence of postoperative morbidities, including postoperative pancreatic fistula rate or stomach-related complications. The hemoglobin A1C (HbA1c) levels in the DG group after surgery decreased to the normal range. Conclusion Our study suggested that the remnant stomach may be safely preserved when performing DP in patients with a history of DG with respect to short-term morbidities. However, there are some concerns about the long-term nutritional status in patients with a history of DG.
