Abstract

Autolysis is the enzymatic digestion of cells by the action of its own enzymes, and it mostly occurs in dying or dead cells. It has previously been suggested that prolonged procedure time could lead to autolytic changes from the periphery of the endoscopic submucosal dissection specimens. Recently, the authors have experienced a case of autolysis; due to the presence of ulcer, fibrosis, and frequent bleeding from the cut surface, it took 6 hours to complete the resection. More than halfway through the resection; bluish purple discoloration of the part of the dissected flap where the dissection was initiated was noticed. Histologic examination of this site showed diffuse distortion of epithelial lining and cellular architectures along with loss of cell components, compatible with autolysis. Because autolysis could theoretically pose a potential problem regarding the evaluation of resection margin, endoscopists and pathologists should communicate with each other for a reliable pathologic decision.
