Treatment of XXXX by transanal endoscopic microsurgery: 15 years' experience.

@entity1 @entity652
BACKGROUND: The authors present their experience with @entity652 managed by transanal endoscopic microsurgery (TEM). The goals of this study were to examine our institution's experience by evaluating surgical morbidity, mortality, and local recurrence rate. METHODS: This retrospective study investigated 402 @entity1 who underwent TEM a for preoperative diagnosis of @entity652 from January 1993 to October 2008. The mean age was 65 years (range = 22-92 years). All @entity1 were regularly followed up to determine treatment efficacy in terms of local recurrence rate. RESULTS: No 30-day perioperative mortality occurred. No conversion to laparoscopic or open procedures was reported. Minor complications occurred in 28 (7%) @entity1 , whereas major complications were found only in 2 (0.5%) @entity1 . Definitive histology confirmed @entity652 in 366 cases (91%). At a mean follow-up of 84 months (range = 1-190 months), 16 (4%) @entity652 recurred and were successfully retreated by TEM [14 cases (87.5%)] and by conventional surgery [2 @entity1 (12.5%)]. No further recurrences were observed at subsequent follow-up. CONCLUSION: The findings warrant the conclusion that TEM is a safe, effective treatment for @entity652 where endoscopic removal is not applicable and has low morbidity and no mortality.
