Multi-stage surgery to treat oesophageal fistula that developed after chemoradiotherapy in two patients with oesophageal cancer: A case report.
International Journal of Surgery Case Reports 2024 March 5
INTRODUCTION AND IMPORTANCE: Oesophageal fistula is a severe complication that may occasionally develop after chemoradiotherapy (CRT) for oesophageal cancer and is difficult to treat.
CASE PRESENTATION: A 51-year-old man who had undergone CRT for oesophageal cancer presented with haematemesis and was diagnosed with a descending aortic aneurysm and an oesophageal fistula. Thoracic endovascular aneurysm repair was performed to achieve haemostasis. After 3 days, the patient underwent subtotal oesophagectomy and cervical oesophagostomy with delivery of a pedicled omental flap to the exposed aortic stent. Six months later, ileocecal reconstruction was performed. The second patient was a 49-year-old woman who had undergone CRT 1 year previously. She complained of leg weakness and gait disorder. After a workup, she was diagnosed with perforation of the posterior wall of the cervical oesophagus with abscess formation and purulent spondylitis. After two spinal fusion surgeries, we performed tracheotomy and drained the cervical region to reduce local infection. After 7 days, she underwent pharyngolaryngoesophagectomy and reconstruction using a gastric conduit, to which a large section of the omental flap was attached. After the multi-stage surgery, oral intake became possible, and both patients were discharged.
CLINICAL DISCUSSION: The optimal treatment strategy for post-CRT oesophageal fistula remains controversial. Radical surgery, including oesophagectomy, is the treatment of choice, although it is associated with high mortality rates. Multi-stage surgery may be useful for reducing surgical stress in moribund patients.
CONCLUSION: We reported two cases involving radiation-induced oesophageal fistula successfully treated by multi-stage surgery without major complications.
