Abstract
Total laryngopharyngoesophagectomy defects after surgical ablation for laryngopharyngeal carcinoma with involvement of the cervical esophagus represents a challenge to the reconstructive surgeon. Complicating an already challenging operation is when surgical ablation occurs after failure of primary chemoradiation requiring the surgeon to operate and reconstruct in an irradiated field limiting potential reconstructive options. Due to the advanced stage at diagnosis, some studies have shown that while traditional management with radiotherapy may be considered as an initial treatment modality, often times this has failed to provide sustainable improvement in survival with reported high local recurrence rates. With relatively high local recurrence rates following radiotherapy, movement towards aggressive surgical resection is favored in some institutions. Despite this movement, primary treatment with chemoradiation is still commonly used as a primary modality opening up the opportunity for residual or recurrent disease leading the surgeon to perform salvage surgery to eradicate disease after primary treatment failure. With advanced ablative surgery comes the challenge to find an ideal reconstructive option that will optimize functional outcomes which has shown to be particularly challenging when operating in a post-radiated field with a higher risk for pharyngocutaneous fistulas. The authors present a case where reconstruction of such a defect after local failure with primary chemoradiation was successful using a single stage reconstruction with the gastric pull up technique in combination with a pectoralis major myocutaneous flap. As the risk of anastomotic leak is significantly higher in patients following radiation, this method showed utilizing a prophylactic muscle flap at the time of reconstruction may further bolster the repair and prevent anastomotic leak.
