Objective To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). Methods The recent l iterature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. Results There were two techniques of minimally invasive approach for CSR at peresent: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneouspuncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopicdiscectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local l igamentum flavum thickening and spondylotic foraminal stenosis. Conclusion The minimally invasive procedure has the advantages of simple handl ing, minimally invasive and low incidence of compl ications. But the scope of indications is relatively narrow at present.
Objective To summarize the experience of sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst under ultrasound guided percutaneous catheter drainage combined with endoscopic technique. Methods The clinical data of 30 patients with aged and high risk pancreatic pseudocyst treated from January 2009 to January 2012 in this hospital were analyzed retrospectively. Results Percutaneous tubes were successfully placed in 30 patients， cystic liquid was sufficiently drained， and the compression symptom of cyst was relieved immediately. After stable disease， 12 patients with communicating cysts were diagnosed by using endoscopic retrograde cholangiopancreatography. Pancreatic duct stents were inserted in 12 patients with communicating cysts for 60-90d （with an average 70d） after endoscopic sphincterectomy and endoscopic pancreatic sphincterectomy. Cysts disappeared in the other 18 cases receiving external drainage with external drainage tubes， the drainage time was 15-90 d with an average 30d. Neither recurrence nor complications were found in all the cases during 12-21 months （with an average 18 months） follow-up. Conclusion Interventional ultrasound combined with endoscopic technique sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst has superiorities in little trauma， fewer complications， and exact effect.
