Background
Bevacizumab is the first angiogenesis inhibitor to be approved for metastatic colorectal cancer. Unfortunately, bevacizumab treatment has been associated with a variety of complications including haemorrhage, poor wound healing and gastrointestinal perforation. Late anastomotic breakdown related to bevacizumab therapy however has rarely been described.
Case report
Here, we present the case of a 56-year-old woman who had a bevacizumab-related anastomotic breakdown 17 months following her primary anastomosis. She initially underwent an emergency Hartmann’s procedure and two further laparotomies for significant intra-abdominal haemorrhage. Despite the best efforts of the surgical and intensive care teams, ultimately, the patient passed away.
Discussion
There is a small but growing body of literature relating to bevacizumab use and late anastomotic breakdown. It would seem prudent to take extra caution when using bevacizumab in those patients with previous pelvic irradiation, who have a rectal site of anastomosis or have experienced a previous anastomotic leak.
