Patients and Methods: A 68-year-old patient with progressive exacerbation of Miles’ postoperative intestinal obstruction was retrospectively analyzed. Conservative treatment was ineffective, and surgery was performed again. Surgery confirmed that the obstruction was caused by a pelvic floor peritoneal hernia. The original reconstruction peritoneal suture needle spacing was too wide, resulting in peritoneal hiatus. Results: The early postoperative intestinal obstruction in this patient was not caused by inflammatory intestinal obstruction, stenosis of stoma, and intestinal adhesion, but by the formation of pelvic floor peritoneal hernia. Conclusion: Pelvic floor peritoneal hernia should not be ignored in the early stage of intestinal obstruction after Miles’ operation. Improper suture during pelvic floor peritoneal reconstruction is the main cause of pelvic floor peritoneal hernia.展开更多

In this paper, game theory is introduced to optimize the subjective and objective weights of the index, and the comprehensive weights are obtained by normalization. The results show that the eigenvalues of the grade variables of benefit evaluation decreased from 3.43 to 2.03, indicating that the project of mountain flood disaster prevention and control in Jiangxi province brings into play the benefits year by year, and the eigenvalues tend to decrease steadily after 2012, it is consistent with the changes of various engineering measures and non-engineering measures in the project.展开更多
