    Abstract Text A LSL-G with evidence of invasive cancer was found on the posterior wall of the proximal rectum in a 65 year old male with positive iFOBT. Pre-resection imaging showed no evidence of lymph-node or distant metastasis. Endoscopic submucosal dissection was attempted using multi-band traction. Centrally under the lesion there was difficult access to the thin submucosal plane despite adequate traction. Combined with concern for deep invasion based on endoscopic imaging this led to the decision to perform endoscopic intermuscular dissection (EID) to achieve R0. The circular muscle fibers of the muscularis propria (MP) were transected and EID underneath the lesion was performed. The defect was closed due to full-thickness perforation around a site of bleeding. EID is therefore possible in the proximal rectum but potentially at significant risk for perforation requiring defect closure.
