One hundred and fiftytwo patients were followed up patients (follow-up rate 79%).The operative outcome and postoperative complications were retrospectively analyzed.RESULTS: Early complications included urine retention in 2patients, enteritis in 10, anastomotic stricture in 1, and intestinal obstruction in 2. No infection of abdominal cavity or wound and anastomotic leakage or death occurred in any patients. Late complications were present in 22 cases,including adhesive intestinal obstruction in 2, longer anal in 5, incision hernia in 2, enteritis in 6, occasional stool stains in 7 and 6 related with improper diet. No constipation or incontinence occurred in any patient.CONCLUSION: The early and late postoperative complication rates were 7.8% and 11.4% respectively in our 'heartshaped anastomosis' procedure. 'Heart-shaped'anastomosis procedure for Hirschsprung's disease provides a better therapeutic effect compared to classic procedures.展开更多

However, the elliptic systems involving the Hardy inequality and concave-convex nonlinearities have seldom been studied and we only find few results. Thus it is necessary for us to investigate the related singular systems deeply. In this paper, a quasilinear elliptic system is investigated, which involves multiple Hardy-type terms and concave-convex nonlinearities. To the best of our knowledge, such a problem has not been discussed. By using a variational method involving the Nehari manifold and some analytical techniques, we prove that there exist at least two positive solutions to the system.展开更多
