Description
Yue Sun, Shishir Karna, Yue Li, and Bixiong Zhang report in a 2026 video case a salvage scope dissection of a tattooed colon lesion. Carbon tattoo dye marks lesions for surgery but clouds the cutting layer for scope work. Their patient needed that scope route after surgery fell through.
The 63 year old man first had a polyp cut that proved to be adenocarcinoma. Tattooing marked the spot for a planned laparoscopy, aborted over gas intolerance. Salvage dissection used a double clip rubber band rig for counter pull. A fine point incision hugged the muscle layer through the dyed tissue. Bleeding stop powder then gelled over the wound bed with water.
