The challenge in the surgical management of pharyngo-esophageal (PE) tumor lies in its deep-seated location behind the manubrium in the cervicothoracic region, in close proximity to great vessels in the lower neck and superior mediastinum. Classically curative surgery is in the form of total pharyngo-laryngo-esophagectomy (PLE) and gastric pull-up (GPU) whereby the entire esophagus is removed en-bloc with the tumor to ensure adequate distal resection margins, and provide a passage-way for reconstruction with a pedicled gastric tube. However PLE and GPU is a major undertaking associated with high operative morbidity and in-hospital mortality rates. We hereby propose tumor resection via a transcervical approach for a patient with recurrent pharyngo-esophageal tumor post definitive chemoradiotherapy: manubrium was resected (MR) to enable adequate exposure and resection of PE tumour under direct vision i.e. pharyngo-laryngo-cervico-esophagectomy (PLCE). The lower esophagus which was devoid of tumor was preserved, thereby reducing peri-operative morbidity and in-hospital mortality. The trachea was transected and re-sited as a mediastinal tracheostoma. Superior mediastinal lymph node dissection could be performed in case of nodal metastasis. Reconstruction of the resultant PE defect was by means of free jejunal (FJ) flap. FJ flap was the preferred reconstructive modality as it offered the lowest pharyngo-cutaneous fistula and anastomotic stricture rates, and donor site morbidities. Gastrograffin swallowing study on post-operation day 10 showed no radiological evidence of anastomotic leakage. Patient was discharged 12 days post-operation on normal solid diet. In summary, MR, PLCE and FJ flap can be adopted in the surgical management of isolated PE tumours.
