ObjectiveTo analyze risk factors of gastric paralysis following pancreaticoduodenectomy so as to offer help for prevention and treatment of gastric paralysis. MethodDomestic and international literatures about gastric paralysis following pancreaticoduodenectomy were collected, diagnostic criteria, risk factors, and the latest progress of gastric paralysis were summarized. ResultsGastric paralysis is one of the most common postoperative complications following pancreaticoduodenectomy. It might be caused by many risk factors, such as operation method, gastrointestinal anastomosis, abdominal complications, chronic hyperglycemia, and excess infusion, etc. ConclusionsAlthough definition of gastric paralysis by ISGPS is widely adopted, it fails to distinguish gastric paralysis from impaired gastric function related to other postoperative complications and it might result in an overestimation of its true morbidity. The risk factors of occurrence of gastric paralysis are still in controversy and results of research in different centers are not same, more prospective randomized controlled trials are needed.
ObjectiveTo explore risk factors of gastric paralysis following gastrectomy of gastric cancer and analyze its causes. MethodsThe clinical data of 116 patients with gastric cancer for hospitalization time more than 21 days following gastrectomy were retrospectively analyzed from October 2011 to October 2013 in this hospital, in which 16 patients with gastric paralysis and 116 patients without gastric paralysis. The factors relevant gastric paralysis were analyzed by logistic regression analysis. ResultsThe results of single factor analysis showed that the preoperative body mass index, history of diabetes, operative time, postoperative cardiovascular complications, albumin and hemoglobin levels within 3 d after operation, time to get out of bed after surgery, extubation time of gastric tube, the first drinking time and the first feeding time were associated with the gastric paralysis (P < 0.05), but the gender, age, time of diabetes history, life mode, smoking history, hypertension history, pylorus preserving or not, laparoscopy or not, intraoperative blood loss, intraoperative blood transfusion, uses of postoperative intraperitoneal chemotherapy drugs and postoperative analgesic drugs, and indwelling time of jejunum nutrition tube were not associated with gastric paralysis (P > 0.05). The results of logistic regression analysis showed that the preoperative body mass index, history of diabetes, operative time, time to get out of bed after surgery, and postoperative cardiovascular complications were the independent risk factors of gastric paralysis (P < 0.05). ConclusionsThere are many factors that affect occurrence of gastric paralysis following gastrectomy of gastric cancer. Preoperative or intraoperative positive prevention measures could be taken according to the factors that might affect occurrence of gastric paralysis, which might be reduce gastric paralysis following gastrectomy of gastric cancer.
