Minimally invasive step-up approach is both safe and effective, but sometimes requires multiple access sites.METHODS: A 62-year-old woman was admitted with diabetic ketoacidosis, and initial computed tomography(CT) revealed no evidence of acute pancreatitis. She was clinically improved with insulin therapy, fl uid administration, and electrolyte replacement. However, on the 14 th day of admission, she developed a high-grade fever, and CT demonstrated evidence of acute necrotizing pancreatitis with a large collection of peripancreatic fl uid. Percutaneous transgastric drainage was performed and a 14 French gauge(Fr) pigtail catheter was placed 1 week later, which drained copious pus. Because of persistent high-grade fever and poor clinical improvement, multiple 8 and 10 Fr pigtail catheters were placed via the initial drainage route, allowing the safe and effective drainage of the extensive necrotic tissue that was occupying the bilateral anterior pararenal space.RESULTS: After drainage, the patient recovered well and the last catheter was removed on day 123 of admission.CONCLUSIONS: Multiple percutaneous drainage requires both careful judgment and specialist skills. The perforation of the colon and small bowel as well as the injury of the kidney and major vessels can occur. The current technique appears to be safe and minimally invasive compared with other drainage methods in patients with extended, infected necrotic pancreatic pseudocysts.展开更多

Before surgery as well as 1 d and 3 d after surgery, serum was collected to determine the contents of stress response molecules and bone metabolism markers.Results:1 d and 3 d after surgery, serum stress molecules PGE2, CRP, NE and E as well as bone resorption markers TRACP-5B,β-CTX, RANK and RANKL contents of both groups were higher than those before surgery while bone formation markers BGP, BALP, PINP and OPG contents were lower than those before surgery;serum stress molecules PGE2, CRP, NE and E as well as bone resorption markers TRACP-5B,β-CTX, RANK and RANKL contents of MIPO group were lower than those of ORFI group while bone formation markers BGP, BALP, PINP and OPG contents were higher than those of ORFI group.Conclusion: Compared with ORIF, MIPO for middle humeral shaft fractures can reduce stress response degree and improve bone metabolism.展开更多
