  • Title: Delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy.
    Author: Shan YS, Hsieh YH, Sy ED, Lin PW.
    Journal: J Formos Med Assoc; 2004 Oct; 103(10):767-72. PubMed ID: 15490027.
    Abstract:
    BACKGROUND AND PURPOSE: Pylorus-preserving pancreaticoduodenectomy is associated with a high incidence of delayed gastric emptying. The aim of this study was to determine the incidence and risk factors for delayed gastric emptying after this procedure. METHODS: This retrospective study included 63 consecutive patients who received pylorus-preserving pancreaticoduodenectomy from July 1993 to December 2002. The patients were divided into 2 groups based on the presence of delayed gastric emptying. Preoperative indices, postoperative morbidity, nasogastric intubation, and hospital stay were compared. The risk factors for delayed gastric emptying were analyzed. RESULTS: The postoperative incidence of delayed gastric emptying was 44% (28/63 patients). Multivariate analysis revealed that no preoperative biliary drainage, no cholestatic change in the liver and blood loss > 400 mL were significant risk factors for delayed gastric emptying. CONCLUSIONS: Pylorus-preserving pancreaticoduodenectomy is a safe procedure with a high incidence of delayed gastric emptying. Delicate surgical dissection to decrease blood loss and the extent of perigastric inflammation may be the key factor to prevent delayed gastric emptying.
