A Case of Achieving Complete Remission with Combination of Stereotac-tic Body Radiation Therapy and Transarterial Chemoemoblization in Pa-tients with 4.8 cm Sized Infiltrative Hepatocellular Carcinoma with Arte-riovenous Shunt

Infiltrative hepatocellular carcinoma (HCC) patients have a poor prognosis because most patients present with advanced disease. Although tumor size is small, ablation therapy is difficult because it is difficult to delineate tumor boundary and tumor often combined vascular invasion. Therefore many clinicians still try locoregional therapy (LRT) such as transarterial chemoembolization (TACE), radiation therapy (RT), or combination with LRT and sorafenib in this situation. Stereotactic body radiation therapy (SBRT) is new technology providing very highly conformal ablative radiation dose and is expected to salvage modality for HCC showed incomplete response of TACE due to combined arteriovenous (AV) shunts. Based on above suggestions, we herein offer our experience of a complete remission of tumor by combination of SBRT and TACE in a patient with infiltrative HCC. Further study, maybe regarding a combination of locoregional and systemic therapy is necessary on how to manage infiltrative HCC with AV shunts.

Extramedullary Plasmacytoma of the Pancreas Diagnosed Using Endoscopic Ultrasonography-Guided Fine Needle Aspiration

Extramedullary plasmacytoma involves organs outside the bone marrow; however, involvement of the pancreas is rare. We recently experienced a case of extramedullary plasmacytoma of the pancreas that was diagnosed by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). EUS-FNA, which has a high diagnostic accuracy and an excellent safety profile, is the modality of choice for establishing tissue diagnosis. We report a case of extramedullary plasmacytoma of the pancreas diagnosed using EUS-FNA.

A Case of Primary Pneumatosis Cystoides Intestinalis in a Patient with Chronic Abdominal Pain

Pneumatosis cystoides intestinalis is a rare phenomenon presenting with multiple gas-filled cysts in the submucosal or subserosal layer of the gastrointestinal tract. Pneumatosis cystoides intestinalis can occur as a primary or secondary disease with an underlying etiology. We recently managed a case of primary pneumatosis cystoides intestinalis in a 42-year-old man with chronic abdominal pain. The case is presented with a review of the literature.

A Case of Cholangiocarcinoma Suspected by Continuous Elevation of CA 19-9 after Surgery of Xanthogranulomatous Cholecystitis / 대한소화기학회지

Xanthogranulomatous cholecystitis (XGC) is an unusual and destructive inflammatory process that is characterized by thickening of the gallbladder (GB) wall with a tendency to adhere to neighboring organs. XGC is often mistaken for GB carcinoma, and the frequency of the coexistence of these two lesions is approximately 10%. Therefore, in case of severe XGC, there is chance of either overlooking the carcinoma or other significant lesions. CA 19-9 is commonly measured in the serum of patients with hepatobiliary malignancies. Although CA 19-9 can be elevated in benign conditions such as cholestasis, pancreatitis, tuberculosis, thyroid disease etc., malignancy should be considered at first in setting of its significant and persistent elevation. We report a case of a 62-year-old man who showed continuously rising level of CA19-9 over 2000 U/mL after cholecystectomy for xanthogranulomatous cholecystitis and finally was diagnosed as cholangiocarcinoma by short-term follow up.

Palliative Self-expanding Metal Stents in the Treatment of Malignant Colorectal Obstruction

BACKGROUND/AIMS: This study was designed to evaluate the outcomes of self-expanding metal stents (SEMS) as palliative treatment for malignant obstruction of the colon and rectum. METHODS: From January 2003 to September 2009, 28 patients (12 men and 16 women) with malignant colorectal obstruction received placement of uncovered or covered stents for palliative purposes under endoscopic or fluoroscopic guidance. The rates of technical success, clinical success, and the complications associated with stent insertion, patient survival, and long-term stent patency were evaluated. RESULTS: The technical and clinical success rates were 100% (28/28) and 89.3% (25/28), respectively. Among the 25 patients with technical and clinical success, seven patients (28%) experienced complications: A case of perforation (n=1) was managed by surgical intervention, cases of tumor ingrowth (n=4), tumor ingrowth and overgrowth (n=1), and tumor overgrowth (n=1) were managed successfully with an additional stent. The median survival duration was 128.0+/-54.8 days. The median stent patency duration was 93.0+/-29.1 days, and the patency rates at 30, 90, and 180 days were 92%, 52%, and 25%, respectively. CONCLUSIONS: The placement of a self-expanding metal stent was safe and effective palliative treatment for malignant colorectal obstruction. Stent-associated complications can be managed with the placement of additional stents in the majority of the patients and long-term stent patency is favorable.

Antibiotics-associated Diarrhea and Other Gastrointestinal Abnormal Responses Regarding Helicobacter pylori Eradication / 대한소화기학회지

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) is closely related with a wide range of gastrointestinal disease. One-week triple therapy is currently considered as the golden standard for the treatment of H. pylori infection. However, gastrointestinal abnormal responses are major pitfalls in such regimen. The aim of this study was to identify symptoms, frequency and severity of antibiotics-associated gastrointestinal abnormal responses during H. pylori eradication therapy. METHODS: Sixty-seven patients with H. pylori infection between September 2005 and March 2006 were included. After 1 week of H. pylori eradication triple therapy (rabeprazol 10 mg, clarithromycin 500 mg, amoxicillin 1 g bid), we evaluated gastrointestinal abnormal responses (diarrhea, bloating, constipation, abdominal pain, borborygmus, flatulence, stool frequency, belching, and nausea) and severities every week for 4 weeks. RESULTS: The incidence of diarrhea was the highest in week 1, which was 41.28% (n=28) and the lowest in week 4, which was 9.52% (n=6) and decreased from week 1 to week 4 with statistical significance (p<0.0001). The most common gastrointestinal abnormal responses were associated with flatulence in week 1 (n=21, 31.34%), week 2 (n=21, 33.33%) and abdominal distention in week 3 (n=16, 25.40%), week 4 (n=15, 23.81%). Most of gastrointestinal abnormal responses were mild, and the most common symptom with higher than moderate grade was abdominal pain (n=4, 40.00%) in week 1. Alcohol consumption and coexisting medical illness were not associated with diarrhea (p=0.0852, 0.9009 respectively). CONCLUSIONS: H. pylori eradication therapy is commonly associated with antibiotics-associated gastrointestinal abnormal responses, which may result in antibiotics intolerance and H. pylori eradication failure. Even though those symptoms are not so severe, we have to consider the gastrointestinal abnormal responses associated with H. pylori eradication, especially diarrhea.

Myocardial Bridging of the Left Anterior Descending Coronary Artery: Depiction Rate and Morphologic Features by Dual-Source CT Coronary Angiography

OBJECTIVE: To evaluate the depiction rate and morphologic features of myocardial bridging (MB) of the left anterior descending coronary artery (LAD) using dual-source CT (DSCT). MATERIALS AND METHODS: CT scans from a total of 1,353 patients who underwent DSCT were reviewed retrospectively for LAD-MB. Seventy-eight patients were excluded due to poor image quality or poor enhancement of the coronary artery. The length and depth of the MB were analyzed and classified as superficial or deep with respect to the depth ( 1 mm) of the LAD tunneled segment. Superficial MB was subdivided into complete or incomplete types according to full or partial encasement of the myocardium. RESULTS: Of the 1,275 patients included in this study, 557 cases of MB were found from 536 patients (42%). Superficial MB was observed in 368 of 557 (66%) cases, and deep MB was seen in 189 of 557 (34%) cases. Superficial MB showed 2 types: complete (128 of 368, 35%) and incomplete (240 of 368, 65%). The mean length of a tunneled segment for superficial MB was 16.4 +/- 8.6 mm. The mean length and depth of a tunneled segment for deep MB were 27.6 +/- 12.8 mm and 3.0 +/- 1.4 mm, respectively. The incidence of atherosclerotic plaques in a 2-cm-long segment proximal to MB was 16%. CONCLUSION: The depiction rate of LAD-MB using DSCT in a large series of patients was 42%, with two-thirds of MB segments being the superficial type.
