简介：AbstractObjective:Chinese rhubarb is a promising Chinese medicine for the promotion of gastrointestinal function. This study was conducted to investigate the safety and efficacy of Chinese rhubarb administered via ultrasound delivery in promoting the early recovery of gastrointestinal function after gastrectomy.Methods:In this prospective randomized controlled study, 100 patients who were scheduled to undergo total or subtotal gastrectomy in Changzhi People’s Hospital or Subei People’s Hospital from August 2017 to January 2018 were recruited. These patients were randomly assigned into two equal groups before surgery: 50 in the experimental (Chinese rhubarb) group, and 50 in the control (routine nursing) group. After surgery, time to flatus, bowel movement, clear liquid diet, and removal of nasogastric tube were recorded and analyzed. In addition, postoperative pain, postoperative bowel movement-related complications, and postoperative hospital stay duration were also recorded and analyzed. The study was approved by The protocol was approved by the Institutional Review Board of Changzhi People’s Hospital and Subei People’s Hospital on July 1, 2017 and registered with the Chinese Clinical Trial Registry on December 17, 2018 (registration number: ChiCTR1800020143).Results:Time to flatus (control group 85.68±22.00 hours vs experimental group 73.06±23.42 hours; P=0.007), bowel movement (5.52±1.56 vs 4.40±1.21 days; P<0.001), clear liquid diet (6.72±1.16 vs 6.22±1.28 days; P=0.044), and removal of nasogastric tube (6.30±1.52 vs 5.65±1.58 days; P=0.044) were significantly shorter in the experimental group compared with the control group, as was the postoperative hospital stay duration (14.30±3.46 vs 12.86±1.36 days; P=0.006). In addition, better pain relief (P=0.003) and a lower incidence of postoperative bowel movement-related complications (6 vs 21; P=0.001) were noted in the experimental group.Conclusion:Ultrasound delivery of Chinese rhubarb is useful to promote the early recovery of gastrointestinal function after gastrectomy.

简介：AbstractObjective:To identify risk factors for anastomotic leakage after gastrectomy in patients with Siewert type II/III adenocarcinoma (AEG) of the esophagogastric junction.Methods:This was a retrospective case-control study of 903 patients with Siewert type II/III AEG treated from January 2012 to January 2015 at the Shanxi Cancer Hospital in China. All patients underwent gastrectomy, and their clinical characteristics were analyzed to identify associations with anastomotic leakage. Independent risk factors were identified by binary logistic regression. The 2-year disease-free survival was calculated and compared between patients with anastomotic leakage and control patients. The study was approved by the Institutional Review Board of Shanxi Medical University (approval No. 2014-09-39) on September 19, 2014.Results:Out of the 903 patients were included in the study, 80 (8.86%, 80/903) experienced anastomotic leakage. The mortality rate attributed to anastomotic leakage was 8.75% (7/80). Logistic regression analysis revealed that preoperative hypoalbuminemia (odds ratio (OR)=3.249, 95% confidence interval (CI): 1.569-6.725, P=0.002), type of reconstruction (OR=1.795, 95% CI: 1.026-3.142, P=0.040), and combined organ resection (OR=1.807, 95% CI: 1.069-3.055, P=0.027) were independent risk factors for anastomotic leakage.Conclusion:Preoperative hypoalbuminemia, type of reconstruction, and combined organ resection were identified as risk factors for anastomotic leakage in patients undergoing gastrectomy for Siewert type II/III AEG.
