The rate of recurrence in patients undergoing conventional EMR is higher than ESD. The aim of our study was to compare the safety, cost and efficacy of esophageal EMRL and ESD. Methods: A total of 152 patients were enrolled from our database on the basis of the following criteria: (1) histologically confirmed ESCC or HGIEN in the EMR or ESD specimens,

(2) tumor invasion depth of epithelium to muscularis LEE011 supplier mucosae, (3) no prior therapy for ESCC. They were divided into two groups: an ESD group and an EMRL group. ESD and EMRL have been performed for superficial squamous cell cancer and HGIEN since Dec 2006 and Dec 2008, respectively. Follow-up was done at 1, 3, 6, 12 months after resection, then annually. Rates of complications, devices cost, procedure time,

Doxorubicin concentration and recurrence rate in the two groups were compared. Statistical analysis done by Mann Whitney U-test and chi-square. Results: There was no significant difference between the two groups in age or sex, in mean size of the lesions (28 mm vs. 25 mm; p > 0.05), and in recurrence rate. The rates of complications were 9.3% (bleeding), 3.5% (perforation), 5.8% (stenosis) in ESD group and 1.5% (bleeding), 0% (perforation), 6.0% (stenosis) in EMRL group, respectively. The mean procedure time and devices cost were 46 min and 8650 ¥ in ESD group and 21 min and 2300 ¥ in EMRL group, respectively. There was no significant difference between the rates of recurrence and stenosis in the two groups., but the rates of bleeding and perforation, selleck products mean procedure time and devices cost were significantly higher in the ESD group. Conclusion: The efficacy of EMRL method is similar as ESD method for esophageal superficial lesions. And EMRL is a safer, easier and cheaper method for esophageal superficial lesions. Key Word(s): 1.

There have been some studies using EUS-FNB with 19-G Procore needle to find out its feasibility and safety for histopathologic diagnosis, however, technical difficulties were encountered with transduodenal biopsy. The aim of this study was to compare diagnostic accuracy and safety of 22-G FNB Procore device to those of 22-G FNA device for pancreatic solid lesion. Methods: The patients who underwent EUS-FNA or FNB with 22G needle for pancreatic solid lesion were retrospectively reviewed between October 2011 and July 2012, and clinicopathologic data was acquired. Sensitivity and specificity were compared along with safety as well between the FNA and FNB groups.
