The complication rate and mortality rate of traditional emergency surgery for acute obstructive colorectal cancer are very high. Self-expanding metal stent (SEMS) as a bridge to surgery can rapidly decompress the intestinal tract and radical surgery can be performed after the patients’ general condition improve. This technology has been widely developed, but its safety is still controversial, mainly related to the risk of SEMS implantation and its impact on the long-term survival of patients. This article will introduce the rationale, pathophysiology, short-term safety and long-term oncology safety of SEMS implantation, in order to provide basis for clinicians to choose treatment methods.
ObjectiveTo survey and analyze the trend of congenital heart disease (CHD) of regions distribution and medical payment model in Children's Hospital of Gansu Province over the past 11 years, and to provide evidence for diagnosis and treatment strategies for CHD children. MethodsMedical records of the CHD children hospitalized in the Children's Hospital of Gansu Province from 2001 to 2011 were completely collected. Regional distribution, year and other basic information of them were extracted. Data was then analyzed using the SPSS 16.0 software. ResultsA total of 591 CHD children were included. Most of them came from Middle-Long, accounting for 68.87%; while the number of CHD children in the region of East-Long and He-xi had a tendency of growth by year, with average growth speed of 189.42% and 27.62%, respectively. Most of them came from the region which is economic class Ⅲ, accounting for 35.64% (highest) with average growth speed (203.45%). Most of the treatment costs were self-supported before 2005, and health insurance and other social aids were consistently increasing after 2005. Most of the institutions for initial visit were town-level hospitals, accounting for 55.50%, and with average growth speed of 170.18%. ConclusionThe medical demand of CHD children in less-developed regions in Gansu province increases year by year. Government-guided healthcare system should be established and improved so as to basically guarantee the prevention and treatment of CHD in less-developed regions.
ObjectiveTo analyze the effect and prognosis of laparoscopic patch repair of esophageal hiatal hernia.MethodsFrom October 2014 to January 2019, 100 patients with gastroesophageal reflux disease undergoing laparoscopic esophageal hiatus hernia repair were randomly divided into the patch group and the non-patch group. All patients underwent laparoscopic repair of esophageal hiatal hernia plus fundoplication (Nissen’s method). On that basis, the patients in the patch group used special mesh for esophageal hiatal hernia repair, while the ones in the non-patch group did not. All the patients were followed up for a long time. The operative effect, postoperative complication rate, recurrence rate, and satisfaction rate of the patients between the two groups were compared.ResultsA total of 98 patients were successfully followed up for more than one year, including 68 in the patch group and 30 in the non-patch group. One year after surgery, the differences between the patch group and the non-patch group in the improvements of reflux attack, heartburn, dysphagia, and food intake were statistically significant (P<0.05); there was no significant difference between the patch group and the non-patch group in satisfaction rate (82.4% vs. 73.3%, P>0.05); the differences in recurrence rate (2.9% vs. 26.7%) and incidence of dysphagia (47.0% vs. 6.7%) between the patch group and the non-patch group were statistically significant (P<0.05).ConclusionFor the patients with gastroesophageal reflux disease caused by esophageal hiatal hernia, the laparoscopic repair of esophageal hiatal hernia + Nissen fundoplication on the basis of reasonable selection of special mesh for esophageal hiatal hernia can obtain satisfactory clinical effect.
In the process of robot-assisted training for upper limb rehabilitation, a passive training strategy is usually used for stroke patients with flaccid paralysis. In order to stimulate the patient’s active rehabilitation willingness, the rehabilitation therapist will use the robot-assisted training strategy for patients who gradually have the ability to generate active force. This study proposed a motor function assessment technology for human upper-limb based on fuzzy recognition on interaction force and human-robot interaction control strategy based on assistance-as-needed. A passive training mode based on the calculated torque controller and an assisted training mode combined with the potential energy field were designed, and then the interactive force information collected by the three-dimensional force sensor during the training process was imported into the fuzzy inference system, the degree of active participation σ was proposed, and the corresponding assisted strategy algorithms were designed to realize the adaptive adjustment of the two modes. The significant correlation between the degree of active participation σ and the surface electromyography signals (sEMG) was found through the experiments, and the method had a shorter response time compared to a control strategy that only adjusted the mode through the magnitude of interaction force, making the robot safer during the training process.
