Colonic lymphangiomatosis associated with protein-losing enteropathy.

Most lymphangiomas are considered to be lymph vessel anomalies. They can occur anywhere in the body and only rarely affect the intestinal tract. However, as endoscopic examination has become more widespread, gastrointestinal lymphangiomas have been reported more frequently. The overwhelming majority of lymphangiomas are solitary; only several cases of multiple lymphangiomas of the colon have been reported so far (1‐3). Here we report multiple colonic and abdominal lymphangiomas in a young Korean woman who presented with protein-losing enteropathy.

The Value of Peracetic Acid (SCOTELIN®) for Endoscopic Disinfection

Background/Aims: Two percent glutaradehyde has been the reference disinfectant for high-level disinfection, but often requires long period of exposure up to 45 minutes. The aims of this study were to evaluate the effectiveness of a new endoscope disinfectant that uses 0.2% peracetic acid, and to compare the culture-positive rate in each different endoscopes and washers used. Methods: Three endoscopes and two washers that differed in purchase year were used. They were cleansed manually and disinfected with peracetic acid for 10 minutes. A total of 86 gastroduodenal endoscopic sessions were included in the study. Results: Overall culture-positive rate was 37.2%, majority of which came from washings of biopsy channel. There was a significant difference in culture-positive rate according to the machine used. Culture positive rate was 11.4% in recently purchased endoscope and washer used. Of the 28 Helicobactor pylori positive cases, there was one Helicobactor pylori DNA PCR positive case, but no Helicobactor pylori was found. Conclusions: When new endoscope and washer is used, peracetic acid is effective as a disinfectant. Significant difference in culture rate according to the different machine used might come from the aging effect and difference of cleansing power of the washer/
