A woman in her 60s was referred to our hospital with a suspicious finding of obstructive transverse colon cancer. Contrast-enhanced CT also revealed multiple lung, liver, and ovarian metastases, resulting in the diagnosis of cT4aN1bM1c2 cStage IVc obstructive colorectal cancer. Adhesion by huge ovarian tumor and hyperextension of sigmoid colon made it difficult to observe the front view of the transverse colonic tumor by conventional colonoscopy. Therefore, short-type double-balloon enteroscopy was used and enabled us to place colonic stent safely and easily. We underwent primary and ovarian tumors resection without stoma creation. Systemic chemotherapy with bevacizumab was introduced after a good postoperative course. The double-balloon enteroscopy is useful to place colonic stent in a difficult case with conventional colonoscopy.
