Risk factors of gastroparesis syndrome after abdominal non-gastroduodenal operation and its prevention

Objective: To investigate risk factors of gastroparesis syndrome (PGS) after abdominal non-gastroduodenal operation and its prevention. Methods: Clinical data of 22 patients with PGS after abdominal non-gastroduodenal operation was analyzed retrospectively, and compared with the patients of non-PGS after abdominal non-gastroduodenal operation during the same time. The possible influencing factors of PGS were analyzed by single factor analysis and logistic regression analysis. Results: All 13 selected factors related with PGS, including age, disease category (benign and malignant), operation time, intraoperative blood loss, postoperative analgesic pump, postoperative enteral nutrition time, postoperative parenteral nutrition time, perioperative blood glucose level, perioperative nutrition status (anaemia or lower proteinemia), pylorus obstruction before surgery, intra-abdominal infection after surgery, and spiritual factor were related with PGS. The statistical analysis showed that the difference was statistical significant (P<0.05), and gender had no correlation with PGS (P>0.05); non-conditional multivariate analysis showed that malignant tumor, perioperative nutrition status, pylorus obstruction, operation time, blood loss, intra-abdominal infection after surgery, and mental factor were significant related with PGS as dependent variable and related risk factors in single factor analysis as independent variables (P<0.05). Conclusions: PGS is a result of multiple factors, and among these factors, malignant tumor, poor nutrition status, pylorus obstruction before surgery, longer operation-time, more blood loss, intra-abdominal infection after surgery, and mental factor are major risk factors of PGS.
