A Case of Pylephlebitis with Pseudomonas aeruginosa Sepsis and Liver Abscess Secondary to Diverticulitis / 대한소화기학회지

Pylephlebitis, or suppurative thrombophlebitis of the portal venous system, is a rare condition occurring secondary to abdominal infections such as diverticulitis. Pylephlebitis can be diagnosed via ultrasonography or CT scan, and is characterized by the presence of a thrombus in the portal vein and bacteremia. However, the diagnosis may be delayed due to the vague nature of the clinical symptoms, causing morbidity and mortality due to pylephlebitis to remain high. Early diagnosis and immediate antibiotic therapy are important for favorable prognosis. Therefore, pylephlebitis should be considered in the differential diagnosis for cases of nonspecific abdominal pain and fever. We report a case of pylephlebitis secondary to diverticulitis, associated with Pseudomonas aeruginosa sepsis. Such cases have not been widely reported.

A Case of Angiographic Embolization of Aortoenteric Fistula Caused by Endovascular Stent Grafting for an Abdominal Aortic Aneurysm / 대한소화기학회지

Aortoenteric fistula (AEF) developed after treatment for an abdominal aortic aneurysm (AAA) is a rare but usually fatal complication. We report a rare case of AEF bleeding after endovascular stent grafting for AAA which was managed angiographically. An 81-year-old man presented with hematochezia and acute abdominal pain for 1 day ago. Four years ago, an aortic stent was implanted in the infrarenal aorta for AAA. Endoscopies were performed to evaluate the hematochezia. Evidence of gastrointestinal bleeding was observed, but a clear bleeding point was not detected on upper endoscopy and colonoscopy. Contrast-enhanced computed tomography performed subsequently showed that the bleeding point was located in the fourth portion of the duodenum as an AEF caused by an inflammatory process in the stent-graft. Intra-arterial angiography showed a massive contrast leakage into the bowel via a small fistula from around the aortic stent graft site. Embolization was successfully performed by injecting a mixture of glue and lipiodol into the AEF tract. The patient was discharged with no evidence of gastrointestinal bleeding after the embolization.

A Case of Primary Ovarian Lymphoma Presenting as a Rectal Submucosal Tumor

Primary ovarian lymphoma is a rare malignancy whose symptoms or signs are usually nonspecific. In this article, we report a very rare case initially presenting as a rectal submucosal-tumor-like lesion with a defecation disturbance caused by primary ovarian lymphoma with bilateral involvement. A 42-year-old woman visited chungnam national university hospital complaining of persistent defecation disturbance for 6 months. Colonoscopy demonstrated compression of the rectum by an extrinsic mass mimicking a rectal submucosal tumor. Magnetic resonance imaging detected bilateral ovarian tumors, 9.3 cm and 5.4 cm each in diameter, compressing the rectum without enlarged lymph nodes. The diagnosis was established following a bilateral adnexectomy and histological studies of the excised tissue. The tumor was classified as a diffuse large B-cell lymphoma. The patient was prescribed six cycles of standard CHOP (cyclophosphamide, hydroxydaunorubicin, vincristine, prednisolone) regimen and is presently on treatment.

Is Endoscopic Mucosal Resection a Sufficient Treatment for Low-Grade Gastric Epithelial Dysplasia?

BACKGROUND/AIMS: The rate of diagnosis of gastric adenoma has increased because esophagogastroduodenoscopy is being performed at an increasingly greater frequency. However, there are no treatment guidelines for low-grade dysplasia (LGD). To determine the appropriate treatment for LGD, we evaluated the risk factors associated with the categorical upgrade from LGD to high grade dysplasia (HGD)/early gastric cancer (EGC) and the risk factors for recurrence after endoscopic treatment. METHODS: We compared the complication rates, recurrence rates, and remnant lesions in 196 and 56 patients treated with endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR), respectively, by histologically confi rming low-grade gastric epithelial dysplasia. RESULTS: The en bloc resection rate was significantly lower in the EMR group (31.1%) compared with the ESD group (75.0%) (p1 cm with surface redness and depressions. CONCLUSIONS: For the treatment of LGD, EMR resulted in a higher incidence of uncertain resection margins and a lower en bloc resection rate than ESD. However, there was no signifi cant difference in recurrence rate.

An Unusual Case of Duodenal Obstruction due to Metastatic Cervical Cancer

We report a rare case of cervical cancer with duodenal obstruction accompanied by obstructive symptoms, which was treated using duodenal stenting. A 48-year-old woman was diagnosed with stage IV cervical cancer (according to the International Federation of Gynecology and Obstetrics staging system), which had invaded the vagina, the uterine body, and the external iliac and common iliac lymph nodes. Endoscopy showed an encircling mass with erythematous mucosa and luminal narrowing in the second and third portions of the duodenum, which prevented the endoscope from advancing. We placed an uncovered stent in the duodenum, which ameliorated abdominal discomfort, nausea, and vomiting, and simultaneously performed a biopsy. Endoscopic stent insertion appears to be the most effective treatment for duodenal obstruction in patients with advanced cancer.

A Case of Anaplastic Carcinoma of the Pancreas Mimicking a Gastrointestinal Stromal Tumor / 대한내과학회지

Anaplastic carcinoma of the pancreas is an extremely rare but aggressive, rapidly progressive tumor. It often presents with invasion of adjacent organs and distant metastases. Most cases are inoperable and confirmed by autopsy. A correct diagnosis of stomach invasion by anaplastic carcinoma of the pancreas is important due to the risk of bleeding, perforation by rapid tumor growth, and a poor prognosis. However, an accurate diagnosis is difficult as a result of the various clinical presentations, symptoms, and radiological findings. We herein report a case of anaplastic carcinoma of the pancreas in a 78-year-old woman who presented with stomach invasion mimicking a gastrointestinal stromal tumor.

Iatrogenic Left Internal Mammary Artery to Great Cardiac Vein Anastomosis Treated With Coil Embolization

Inadvertent left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomosis is a rare complication of coronary artery bypass graft surgery. Patients with iatrogenic aortocoronary fistula (ACF) were usually treated surgical repair, percutaneous embolic occlusion with coil or balloon. We report a case of iatrogenic LIMA to GCV anastomosis successfully treated with coil embolization and protected left main coronary intervention through the percutaneous transfemoral approach.

Endothelial Dysfunction in the Smokers Can Be Improved with Oral Cilostazol Treatment

BACKGROUND: Smoking is one of well known environmental factors causing endothelial dysfunction and plays important role in the atherosclerosis. We investigated the effect of cilostazol could improve the endothelial dysfunction in smokers with the measurement of flow-mediated dilatation (FMD). METHODS: We enrolled 10 normal healthy male persons and 20 male smokers without any known cardiovascular diseases. After measurement of baseline FMD, the participants were medicated with oral cilostazol 100 mg bid for two weeks. We checked the follow up FMD after two weeks and compared these values between two groups. RESULTS: There was no statistical difference of baseline characteristics including age, body mass index, serum cholesterol profiles, serum glucose and high sensitive C-reactive protein between two groups. However, the control group showed significantly higher baseline endothelium-dependent dilatation (EDD) after reactive hyperemia (12.0 +/- 4.5% in the control group vs. 8.0 +/- 2.1% in the smoker group, p = 0.001). However, endothelium-independent dilatation (EID) after sublingual administration of nitroglycerin was similar between the two groups (13.6 +/- 4.5% in the control group vs. 11.9 +/- 4.9% in the smoker group, p = 0.681). Two of the smoker group were dropped out due to severe headache. After two weeks of cilostazol therapy, follow-up EDD were significantly increased in two groups (12.0 +/- 4.5% to 16.1 +/- 3.7%, p = 0.034 in the control group and 8.0 +/- 2.1% to 12.2 +/- 5.1%, p = 0.003 in the smoker group, respectively). However, follow up EID value was not significantly increased compared with baseline value in both groups (13.6 +/- 4.5% to 16.1 +/- 3.7%, p = 0.182 in the control group and 11.9 +/- 4.9% to 13.7 +/- 4.3%, p = 0.430 in the smoker group, respectively). CONCLUSION: Oral cilostazol treatment significantly increased the vasodilatory response to reactive hyperemia in two groups. It can be used to improve endothelial function in the patients with endothelial dysfunction caused by cigarette smoking.

Technical Feasibility and Early Clinical Outcomes Associated With Distal Filter Device Use for All Carotid Stenting Procedures

BACKGROUND AND OBJECTIVES: Distal filter devices (DFDs) are known to reduce the occurrence of embolic events by capturing embolic debris and thereby preventing intracranial embolization during carotid artery stenting (CAS). However, there are few reports addressing DFD use in CAS procedures. Therefore, we evaluated the technical feasibility and clinical outcomes associated with DFD use in all CAS procedures. SUBJECTS AND METHODS: Between June 2004 and June 2008, all CAS procedures performed at our center were completed with DFD protection. We recorded periprocedural data and watched for new neurologic abnormalities for 24 hours after the procedure. One-month clinical outcomes were also evaluated. RESULTS: A total of 100 carotid lesions in 94 patients (age 68+/-8 years; 79 men) were treated with percutaneous stenting using DFDs (FilterWire EZ(TM), Boston Scientific Co, US). DFD application was successful in all procedures. Periprocedural strokes occurred in five procedures (one major, one minor, and three transient ischemic attacks). The one-month rates of stroke and death were 6% and 2%, respectively. Difficult filter placement occurred in two procedures due to tight stenosis and severe common carotid artery (CCA)-to-internal carotid artery (ICA) angulation. Difficult stent delivery occurred in three instances: one due to severe lesion calcification and two due to proximal tortuosity. The retriever failed to acquire the filter in nine procedures. Four of nine retrieval difficulties were related to severe CCA-ICA angulation. CONCLUSION: DFD use was successful in all CAS procedures, was relatively safe, and had few periprocedural complications.

A Case with Acute Pulmonary Thromboembolism Associated with Nephrotic Syndrome

Though nephrotic syndrome is associated with various thromboembolic phenomena, acute pulmonary thromboembolism is a rare complication. We experienced a case with acute pulmonary thromboembolism in a patient with generalized edema and profound proteinuria. Subsequent investigation revealed that the pulmonary thromboembolism was secondary to nephrotic syndrome due to membranous glomerulonephritis. This thromboembolic complication was successfully treated with thrombolysis and anticoagulation.
