Venous thromboembolism (VTE) is a high-risk complication in hospitalized patients, especially in patients with orthopedic surgery, neurosurgery, thoracic surgery, cardiac surgery and tumor surgery. It is also a significant cause of patients’ unexpected death and perioperative death. Through establishment of norms of VTE management system and organizational structure, formulation of perfect VTE risk assessment system and prevention and treatment scheme for hospitalized patients, training of all the medical staff for related knowledge, and test operation of the system in key departments, we established a hospital standardized system of venous thromboembolism prevention and management. Our VTE prevention and treatment work achieved good results through multidisciplinary collaboration.
ObjectiveTo investigate the feasibility of magnamosis rings designed based on magnetic compression technique in esophageal anastomosis reconstruction.MethodsAccording to the anatomical characteristics of esophagus in SD rats, the esophageal magnamosis rings were designed. SD rats were used as animal models (n=10, 5 males and 5 females) to complete the magnetic anastomosis reconstruction of the cervical esophagus using magnamosis rings, and the operation time, animal survival, postoperative complications, magnetic rings excretion time were recorded. Two weeks after operation, the rats were killed, and the esophageal anastomotic specimens were obtained. The blasting pressure of the anastomotic site was measured and the formation of the anastomotic site was observed with naked eyes.ResultsEsophageal magnamosis was successfully performed in 10 SD rats, and the median operation time was 11 (8-13) min. All rats survived without anastomotic leakage, anastomotic stenosis, or magnetic rings incarceration. The magnetic rings were discharged after 8 (5-10) days and the burst pressure was higher than 300 mm Hg. Visual observation showed that the anastomotic muscle healed well and the mucosa was smooth.ConclusionThe magnetic compression technique can be used for anastomosis reconstruction of esophagus, which has the advantages of simple operation and reliable anastomosis effect, and has clinical application prospect.
