Effective control of relapsing disseminated intravascular coagulation in a patient with decompensated liver cirrhosis by recombinant soluble thrombomodulin.

A 70-year-old Japanese man was hospitalized for expanding purpura and chronic disseminated intravascular coagulation (DIC) caused by decompensated liver cirrhosis. As there are no effective treatments for chronic DIC caused by liver cirrhosis, we decided to administer recombinant human soluble thrombomodulin (rhsTM) after he provided informed consent. The DIC was rapidly improved; however, the purpura and coagulopathy recurred after two months, and repeated rhsTM treatments were required. The rhsTM treatment sufficiently controlled the coagulopathy for two years, without any complications, including bleeding. This is the first report demonstrating that rhsTM can be administered safely and repeatedly to a patient with decompensated liver cirrhosis, and that it appears to be associated with a favorable outcome.

Back-to-back comparison of auto-fluorescence imaging (AFI) versus high resolution white light colonoscopy for adenoma detection.

BACKGROUND: Some patients under close colonoscopic surveillance still develop colorectal cancer, thus suggesting the overlook of colorectal adenoma by endoscopists. AFI detects colorectal adenoma as a clear magenta, therefore the efficacy of AFI is expected to improve the detection ability of colorectal adenoma. The aim of this study is to determine the efficacy of AFI in detecting colorectal adenoma. METHODS: This study enrolled 88 patients who underwent colonoscopy at Asahikawa Medical University and Kushiro Medical Association Hospital. A randomly selected colonoscopist first observed the sigmoid colon and rectum with conventional high resolution endosopy (HRE). Then the colonoscopist changed the mode to AFI and handed to the scope to another colonoscopist who knew no information about the HRE. Then the second colonoscopist observed the sigmoid colon and rectum. Each colonoscopist separately recorded the findings. The detection rate, miss rate and procedural time were assessed in prospective manner. RESULTS: The detection rate of flat and depressed adenoma, but not elevated adenoma, by AFI is significantly higher than that by HRE. In less-experienced endoscopists, AFI dramatically increased the detection rate (30.3%) and reduced miss rate (0%) of colorectal adenoma in comparison to those of HRE (7.7%, 50.0%), but not for experienced endoscopists. The procedural time of HRE was significantly shorter than that of AFI. CONCLUSIONS: AFI increased the detection rate and reduced the miss rate of flat and depressed adenomas. These advantages of AFI were limited to less-experienced endoscopists because experienced endoscopists exhibited a substantially high detection rate for colorectal adenoma with HRE.
