ABSTRACT
BACKGROUND AND AIMS:
Endoscopic submucosal dissection (ESD) is challenging for appendicular lesions. We report the outcomes of ESD in this context.METHODS:
We collected data of ESD procedures for appendiceal neoplasia in a multicenter prospective registry. Main study endpoints were R0, en-bloc, and curative resection rates and adverse event rate.RESULTS:
One hundred twelve patients were included, 47 (42%) with previous appendectomy. Fifty-six (50%) were Toyonaga type 3 lesions (15 [13.4%] postappendectomy). En-bloc and R0 resection rates were 86.6% and 80.4%, respectively, with no significant difference associated with different grades of appendiceal invasion (P = .9 and P = .4, respectively) or previous appendectomy (P = .3 for both). The curative resection rate was 78.6%. Additional surgery was performed in 16 cases (14.3%), including 10 (62.5%) Toyonaga type 3 lesions (P = .04). This included the treatment of 5 cases (4.5%) of delayed perforation and 1 acute appendicitis.CONCLUSIONS:
ESD for appendicular lesions is a potentially safer and effective alternative to surgery for a significant proportion of patients.
