OBJECTIVE: To evaluate the safety and effectiveness of a 20-mm diameter dual-design expandable colorectal stent for malignant colorectal obstruction. MATERIALS AND METHODS: The study series included 34 patients with malignant colorectal obstruction who underwent implantation of a 20-mm dual-design expandable colorectal stent in our department between March 2009 and June 2010. The 20-mm dual-design expandable colorectal stent was placed by using a 3.8-mm delivery system that had 28-mm diameter proximal and distal ends. Among the 34 patients, stent placement for palliation was performed in 20 patients, while stent placement for bridge to surgery was performed in 14 patients. RESULTS: A 97% (33 of 34) success rate was achieved for the stent placement. The perforation rate in the bridge to surgery group was 7% (1 of 14), compared to 0% (0 of 19) in palliative group. Migration occurred in one of 33 patients (3%) at 30 days after stent placement. CONCLUSION: The placement of a 20-mm diameter dual-design stent appears to be clinically safe and effective for the management of colorectal obstruction, with low perforation and migration rates.

PURPOSE: Korea has a parallel system of western and oriental medicine. Therefore doctors of each department have distrust of the other, which in turn confuses the patients and cause discontentment with medical standards. To upgrade the satisfaction of patients that want oriental therapy, we have studied the western-oriental cooperative therapy system to identify its flaw, if any, and tried to find a standard of therapy. METHODS: The 105 Patients included in this study were diagnosed as having a cerebral infarction and were admitted to the neurology department or the oriental medicine department via the emergency department from January to July 2002. We retrospectively analyzed sex, age, severity, admission periods, therapeutic methods and result, and frequency of consulting other departments. RESULTS: At times of admission, the scale of severity showed that there were more severe patients in the western-therapy group. There was no difference in the total prognosis between two groups. In mild patients (GCS>12), western therapeutic results were more favorable than those of the oriental group. In the western-therapy group, 32 (55.2%) patients also received oriental treatment, and 38 (80.9%) patients in the oriental-therapy group received combination of western and oriental therapy. CONCLUSION: From the above study, we propose that patients with unstable vital signs or with acute cerebral infarction should be treated with weatern therapy primarily, with oriental therapy after stabilization, and that mild or longstanding cerebral infarction patients can be admitted to whichever department they want.
