Firm adherence to the mucosa was achieved without the scope slipping back. An average of 2.1 m of insertion was achieved (2.1+/-0.8) in the procedures. Only complication seen was presence of hematoma which resolved eventually. Compared

with our previous experience with DBE, this method could be regarded as comparable in the prevention of slipping backwards, or may even be better. Insertion Dorsomorphin datasheet is easier because administration of suction is easier than inflation and deflation of the scope balloon. Conclusion: In our study, a total of thirteen patients underwent SBE with the anchorage of the tip of the scope with a suction cap. This is a simple and inexpensive addition to augment the advancement of the scope through the small intestine, with an average insertion of up to two meters. Results Adriamycin mw are comparable to those achieved by the DBE in our center, and has the advantage of being cheaper (the cap being cheaper than the balloon and reusable) and easier to operate. This is definitely a method worthy of recommending to colleagues using the SBE. Key Word(s): 1. balloon enteroscopy; 2. suction cap; 3. suction assisted SBE; 4.

Endoscopic submucosal dissection (ESD) is now being increasingly used for these tumors because of high curative resection rate. However, the technical difficulty of ESD repeatedly been shown to be associated selleck chemical with higher complication rate. The aim of this study was to evaluate the efficiency and feasibility of ESD compared with EPMR for esophageal

superficial lesion ≥15 mm, including analysis of risks factors for incomplete resection, local recurrence and severe complications in esophageal ESD. Methods: From September 2009 to August 2011, 63 patients with esophageal lesion ≥15 mm underwent EPMR, while 198 patients underwent ESD. Patient characteristics, procedure time, complications (bleeding, perforation, and stricture), local recurrence and distant metastases were compared between ESD and EPMR. Logistic multivariate analysis was used to analyze the independent factors for en-bloc resection, local recurrence and severe complications in ESD group. Results: The tumor size was significant larger in ESD group compared with EPMR group (3.02 ± 1.13 mm vs. 2.66 ± 0.95 mm, P = 0.
