Background Aims: Rectal carcinoid has been increasingly detected due to the recent wide use of colonoscopy for routine health examination. Although endoscopic resection should be considered as the treatment for rectal carcinoid, the scar formation after colonoscopic biopsy can lead to unpredicted difficulty in this procedure. This study evaluates the per-procedure findings and treatment results in an attempt to elucidate the effect of scar formation after colonoscopic biopsy in endoscopic resection for rectal carcinoid. Methods: Twelve cases of rectal careinoid with scar formation were compared with 18 non-scar cases, which were treated using the endoscopic resection from January 2002 to August 2007, in terms of the endoscopic findings, resection methods and treatment results. Results: The differences in the clinical findings and tumor size between the scar group and the non-scar group were nonspecific. The average waiting-time between biopsy and resection was shorter (13±16 vs 42±26 ds; p=0.11) in the scar group. During endoscopic resection, small active ulcer was found in 4 scar cases with lesser than 7 days of waiting-time. The risk of limited elevation after submucosal injection was higher (83% vs 44%, p=0.03) in the scar group. In resection methods, ESD was frequently adopted in the scar group (4 cases vs 1 case). The difference in the result of pathologic complete resection between two group were nonspecific. Four patients in the scar group should be admitted (vs 1 case in the non-scar group). Conclusions: ESD technique should be considered in selected cases, because of the postbiopsic scar can block the submucosal elevation in endoscopic resection for rectal carcinoid.
