[A Case of Jejunal Perforation by Ramucirumab Just below the Treitz Ligament Treated with Primary Suture].

We present a case of jejunal perforation just below the Treitz ligament treated with primary suture after administration of ramucirumab(RAM). The patient was a 74-year-old male. He was diagnosed with Stage Ⅳ sigmoid colon cancer with liver and lung metastasis. Laparoscopic sigmoid colon cancer resection was performed previously. As adjuvant chemotherapy, the patient received 3 courses of CapeOX plus bevacizumab(BEV)and 20 courses of FOLFOX plus BEV and was in PR. After operation for liver and lung metastases, the patient was observed without any treatment, but pelvic recurrence and lung metastasis were noted, and FOLFIRI plus RAM was started. On the 7th day after the second course, the patient experienced abdominal pain. Since an intestinal perforation was suspected, emergency surgery was performed on the same day. There was a 5-mm-diameter perforation in the jejunum just below the Treitz ligament, and were small ischemic changes near the perforation. The rest of the intestine was clear, the perforation was suspected due to RAM. Since anastomosis was difficult, we performed primary suture and decompression of the location. The postoperative course was uneventful, and the patient was discharged on POD 18. Currently, RAM has been discontinued and chemotherapy is being continued with FOLFIRI.
