The woman was hospitalised and scheduled to receive the following chemotherapy regimen: an IV drip of bevacizumab 280mg, an IV drip of oxaliplatin 130mg, an IV drip of calcium levofolinate 300mg, a rapid IV injection of fluorouracil 600mg, and a constant infusion of fluorouracil 3600mg. All drugs were administered on the first day, and one course was repeated every 2 weeks. She received her first and second courses on day 9 and 23, respectively; however, ileus developed on d30. Her third course was scheduled on day 38, and it was noted that she had no bowel movement for several days; ileus was confirmed by abdominal radiography and CT. The woman was hospitalised and underwent a transanal ileus tube insertion, which temporarily improved the inflammation. Sigmoidectomy was performed on day 43 due to worsening of abdominal findings including abdominal distension and tenderness.

Ileus: case reportA 64-year-old woman with metastatic colorectal cancer
developed ileus as a result of rapid tumour necrosis causingcicatricial contraction and stenosis, during chemotherapywith bevacizumab and mFOLFOX6 (oxaliplatin, calciumlevofolinate and fluorouracil).
The woman was hospitalised and scheduled to receivethe following chemotherapy regimen: an IV drip ofbevacizumab 280mg, an IV drip of oxaliplatin 130mg, an IVdrip of calcium levofolinate 300mg, a rapid IV injection offluorouracil 600mg, and a constant infusion of fluorouracil3600mg. All drugs were administered on the first day, andone course was repeated every 2 weeks. She received herfirst and second courses on day 9 and 23, respectively;however, ileus developed on d30. Her third course wasscheduled on day 38, and it was noted that she had nobowel movement for several days; ileus was confirmed byabdominal radiography and CT.
The woman was hospitalised and underwent a transanalileus tube insertion, which temporarily improved theinflammation. Sigmoidectomy was performed onday 43 due to worsening of abdominal findings includingabdominal distension and tenderness. An analysis of theresected specimen revealed stenosis, and a markedlyshrunk and hardened tumour site. Histopathology showeddestruction of the normal colonic wall structure in the ulcersite, inflammatory cell infiltration, fibrosis and bleeding,with necrosis of more than 2/3 of the cancer tissue. Herpostoperative course was unremarkable, andmFOLFOX6 therapy was resumed, without bevacizumab,on day 66. Two courses were administered, andbevacizumab was subsequently resumed.
