Prediction and Treatment of Difficult Cases in Colorectal Endoscopic Submucosal Dissection
Figure 2
Clinical features of tumors with mild and severe fibroses. (a) There was a significantly higher incidence of severe fibrosis in protruding tumors >40 mm in diameter. However, there was no significant difference in the incidence of fibrosis in superficial tumors. (b) The incidence of severe fibrosis (F2) was higher in protruding tumors and LST-NGPD. F0: no fibrosis, F1: mild fibrosis, F2: severe: fibrosis, LST: laterally spreading tumor, NGPD: nongranular pseudodepressive type, NGF: nongranular flat type, and GM: granular nodular-mixed type, GH: granular homogenous type.
