Two Cases of Electrocautery Incision Therapy Using an Insulated-tip Knife for Treatment of Symptomatic Benign Short-segment Colonic Stenosis Following Colonic Resection / 대한소화기학회지

Anastomotic stenosis of the colon is not an uncommon finding; however, its frequency varies from one study to another. Traditionally, postoperative colonic stenosis is managed surgically. However, endoscopic therapy has recently become the preferred treatment modality over traditional surgery. Good short-term success has been achieved with use of endoscopic balloon dilation; however, restenosis may occur over time in 14% to 25% of patients. The current report showed the effectiveness and usefulness of an insulated-tip knife (IT-knife) for electrocautery therapy of a patient with symptomatic anastomotic colonic stenosis.

Anomalous Separate Origin of Left Anterior Descending Coronary Artery: Presented as Acute Anterior Myocardial Infarction

Coronary artery anomalies are rare presentations in primary percutaneous coronary interventions of acute myocardial infarction. Herein, we report the case of a 59-year-old man with acute anterior myocardial infarction who had anomalous separate origin of left anterior descending artery (LAD) and left circumflex artery (LCX) from the left coronary aortic sinus. Coronary angiography showed a normal right coronary artery and LCX, but no visualization of the LAD. After several unsuccessful attempts to cannulate the LAD, we found the LAD ostium located by the side of the LCX ostium. There was total occlusion at proxymal LAD. Coronary computed tomography angiography demonstrated the precise, separate origin of LAD and LCX from the left coronary aortic sinus.

Encapsulating Peritoneal Sclerosis Occurring in a Hemodialysis Patient / 대한내과학회지

Encapsulating peritoneal fibrosis (EPF) is a serious, uncommon complication of chronic peritoneal dialysis. However, it is rare in hemodialysis patients. EPF is characterized by peritoneal membrane inflammation followed by peritoneal membrane fibrosis and encapsulation. The etiology is unclear, but inflammation of the deteriorated peritoneum causes peritoneal fibrosis. We present a case of EPF that occurred in a 29-year-old man with hepatitis B-associated liver cirrhosis with ascites that was treated solely with hemodialysis. We managed this patient surgically and then medically with prednisolone. To our knowledge, this is the first such case in Korea, so we report this case with a literature review.

The Efficacy and Tolerability of Sugared Polyethylene Glycol for Colonoscopy / 대한소화기학회지

BACKGROUND/AIMS: Although polyethylene glycol (PEG) solution is commonly used for colonoscopic bowel preparation because of its safety and effectiveness, its salty taste decreases patient's compliance. The aim of this study was to compare the sugared PEG solution with the standard PEG solution in regard to the quality of bowel preparation and patient's compliance. METHODS: From January through June in 2012, 100 patients who underwent colonoscopy in Gangneung Asan Hospital were prospectively enrolled. They were randomly assigned to receive either standard PEG solution or sugared PEG solution. The quality of bowel preparation was assessed by a doctor's questionnaire and the patient's compliance was assessed by a patient's questionnaire. RESULTS: There was no significant difference in the quality of bowel preparation (4.2+/-2.0 vs. 4.1+/-1.5, p=0.783), and endoscopist's satisfaction score (8.2+/-1.8 vs. 8.5+/-1.3, p=0.253) between two groups. However, The degree of disgust was lower in the sugared PEG group than the standard PEG group (6.4+/-2.3 vs. 3.9+/-2.9, p=0.000). The willingness to repeat same regimen was higher in the sugared PEG group than the standard PEG group (2.0+/-0.6 vs. 2.3+/-0.7, p=0.004). There was no difference in side effects between two groups. CONCLUSIONS: The sugared PEG solution as a bowel preparation method revealed a higher patient's compliance and was effective as the standard PEG solution. When the patient dislike the taste and saltness of the standard PEG solution, the sugared PEG solution will be good alternative method.
