RESUMO

The technique of endoscopic submucosal dissection is occasionally used for resection of myogenic tumors originating from muscularis mucosa or muscularis propria of stomach and esophagus. However, endoscopic treatments for esophageal myogenic tumors >2 cm have rarely been reported. Herein, we report a case of large leiomyoma originating from muscularis propria in the upper esophagus. A 59-year-old woman presented with dysphagia. Esophagoscopy and endoscopic ultrasonography revealed an esophageal subepithelial tumor which measured 25x20 mm in size, originated from muscularis propria, and was located at 20 cm from the central incisors. The tumor was successfully removed by endoscopic submucosal dissection and there were no complications after en bloc resection. Pathologic examination was compatible with leiomyoma.

RESUMO

BACKGROUND/AIMS: The diagnosis of primary billiary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome remains challenging. In 2008, a simplified scoring system was proposed by the International Autoimmune Hepatitis Group, which aimed for wider applicability in routine clinical practice. We evaluated the performance of the new simplified AIH scoring criteria as a diagnostic tool for overlap syndrome. METHODS: We retrospectively reviewed the clinical histories, chemistry, autoimmune studies, and liver biopsy results of 25 patients diagnosed with PBC who visited Soonchunhyang University Hospital, Bucheon and Seoul, between November 2004 and December 2009. Parameters relevant to the revised and simplified scoring criteria were recorded, and outcomes were compared between those with and without features of overlap syndrome. RESULTS: Of 25 patients with a definite diagnosis of PBC, five (20%) were diagnosed with overlap syndrome using the revised criteria, and 18 patients (72%) were diagnosed with the simplified criteria. Those patients diagnosed according to the simplified scoring criteria revealed an increased frequency of anti-nuclear antibody (p = 0.030) and serum IgG levels (p = 0.092). Additionally, advanced fibrosis was significantly more frequent in patients with overlap syndrome (p = 0.017). CONCLUSIONS: The simplified scoring criteria seemed to be useful as a diagnostic tool to recognize overlap syndrome in Korea. However, a relatively small number of patients were included in our study, so further clinical trials based on larger populations should be performed.

RESUMO

BACKGROUND: Patients with malignancy are considered to be at high risk of severe pandemic influenza A/H1N1 2009. This study was conducted to identify the severity of pandemic influenza A/H1N1 2009 among patients with malignancy. MATERIALS AND METHODS: Between August 2009 and December 2009, we reviewed clinical data and medical records of 31 patients with malignancy and 63 hospitalized patients without malignancy. RESULTS: Eighty-three patients with laboratory-confirmed pandemic influenza A/H1N1 2009 were admitted. The rate of ICU admission was higher among patients with malignancy (without malignancy 13% vs with malignancy 35%, P=0.024). The mortality rate was higher among patients with malignancy (without malignancy 6% vs with malignancy 25%, P=0.033). Patients using immunosuppressants showed a higher rate of lower respiratory tract infection (83% vs 24%, P=0.013). CONCLUSIONS: Pandemic influenza A/H1N1 2009 in patients with malignancy was more severe than in patients without malignancy.

RESUMO

Enteropathy-type T-cell lymphoma (ETL) or enteropathy-associated T-cell lymphoma is a very rare malignant intestinal tumor. ETL is usually diagnosed by surgery. Endoscopic findings of ETL are not well known, and there are few reports of findings from endoscopy that has been performed only using white light. Additionally, there are no definite treatment guidelines for ETL. Therefore, we report a case of ETL diagnosed by enteroscopy with imaging-enhanced endoscopy and also review recently developed treatment options.

RESUMO

OBJECTIVE: Current guidelines for initiating dialysis therapy are based on level of kidney function and clinical evidence of uremia. In several studies, early dialysis showed no benefit in mortality and complication rate. Thus we examined whether the timing of initiation of dialysis influenced mortality and complication rate with renal failure. METHODS: We retrospectively studied the clinical outcomes in 290 patients with renal failure who underwent dialysis therapy from 2001 to 2009. The early and late dialysis group defined as values more than and less than 10 mL/min/1.73 m2. The primary outcome was death from any cause and the secondary outcome was complication event. RESULTS: The survival rates and complication events were compared based on the estimated glomerular filtration rate, the survival rate in late dialysis group is better than in early dialysis group and the significant prognostic factors determined by multivariate analysis were age and residual renal function at time of initiation of dialysis. No difference in complication events were observed. Subgroup analysis in hemodialysis group shows no significant difference in survival rate. CONCLUSION: The survival rate in late dialysis group is better than in early dialysis group. And the complication rate were not different in two groups.

RESUMO

With the increasing use of pancreatic duct (PD) stents after endoscopic papillectomy (EP), complications such as proximal migration of the stent have become increasingly prevalent. A PD stent that migrates within a nondilated PD may be difficult to remove endoscopically. We performed endoscopic retrieval of proximally migrated PD stents after EP in 5 patients. Endoscopic retrieval was performed immediately after EP in one patient, the next day in 3 patients, and 2 weeks later in one patient. Wire-guided endoscopic retrieval was attempted in 4 patients, and the migrated stents were removed successfully in these 4 patients. No significant procedure-related complications occurred, other than mild pancreatitis in a single patient. In one patient, endoscopic retrieval performed immediately after EP failed when using the conventional method, and the migrated stent was removed using a minisnare without a guidewire the next day; this patient developed severe pancreatitis. Wire-guided endoscopic snare retrieval seems to be a safe and effective method for removing proximally migrated PD stents after EP.

RESUMO

BACKGROUND/AIMS: This study compared the clinical benefits of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) with pemetrexed to identify the clinical parameters that correlated with response. METHODS: A retrospective chart review examined patients who were 1) treated with EGFR TKI or pemetrexed, 2) diagnosed with advanced non-squamous non-small-cell lung cancer, and 3) previously treated with platinum-based chemotherapy in Soonchunhyang Bucheon Hospital. RESULTS: Sixty-one patients (18 erlotinib, 18 gefitinib, 25 pemetrexed) were investigated from February 2002 to August 2009. The median follow-up period was 37 months (7~97 months). Overall, their median age was 63 years, 41 patients were non-smokers, 57 patients had adenocarcinoma, and 55 patients were at stage IV. Twenty-one patients received the study drugs as second-line chemotherapy, and others as third-line or more. No significant differences in the overall response rate (erlotinib 33.3% vs. gefitinib 38.9% vs. pemetrexed 20.0%) and progression-free survival (erlotinib 1.9 months vs. gefitinib 3.0 months vs. pemetrexed 2.9 months) were found among the three groups. Female gender was related to a good response to EGFR TKIs (p=0.047). Skin rash in the erlotinib group (p=0.037) and adenocarcinoma in the pemetrexed group (p=0.02) were related to improved progression-free survival. Few side effects were reported. CONCLUSIONS: Both EGFR TKIs and pemetrexed therapy for non-squamous non-small-cell lung cancer were efficient and tolerable after the failure of first-line platinum-based chemotherapy. Further prospective studies are needed to validate the predictive role of the suggested clinical parameters in this study.
