BACKGROUND/AIMS: The aim of this study was to clarify long-term outcomes of endoscopic mucosal resection (EMR) using a modified Buess technique for mucosal @entity356 . METHODS: The procedure included en bloc mucosal resection using a Buess-type rectoscope into the gastric lumen via a temporary gastrostomy under video camera guidance. We reviewed 5 @entity1 who underwent this procedure between 1995 and 1997 with a single mucosal @entity5 that was unsuitable for en bloc excision by endoscopic snare diathermy. RESULTS: All @entity5 were superficial elevated types (type 0-IIa) located in the middle third and posterior wall of the stomach. Median maximum @entity5 diameter was 2.2 (range 1.1-3.5) cm. There was no operative mortality. One @entity1 developed a hemorrhagic gastric ulcer postoperatively. All @entity5 histologically showed curative potential of the mucosal resection without margin involvement. During a median follow-up period of 64 (50-77) months, none of the @entity1 developed local recurrence. One @entity1 had an @entity356 that metachronously developed at another stomach site. CONCLUSION: Intragastric EMR using a modified Buess technique appears to be a useful treatment for cure of mucosal @entity356 for a limited group of @entity1 unsuitable for complete en bloc excision by endoscopic snare diathermy.
