Factors resulting in postoperative dysphagia following esophagectomy: a narrative review

Esophagectomy is a technically involved surgery and can have significant postoperative morbidity. Although the mortality rate following esophagectomy has decreased in recent years, this surgical procedure has a relatively high complication rate compared to other surgeries to resect cancer. One of the most common complaints after esophagectomy is dysphagia. Dysphagia after esophagectomy can significantly affect quality of life. Dysphagia is a complication following esophagectomy that can lead to respiratory deterioration and death. The most common sites of postoperative dysphagia are the gastroesophageal anastomosis, gastric conduit, pylorus and the hiatus. Without appropriate treatment of dysphagia, malnutrition and dehydration can develop. These factors can lead to significant impacts to the overall health of a patient and increase mortality. A detailed literature review provided data to support diagnostic modalities and management strategies to treat postoperative dysphagia at these common areas. A systematic, evidence-based approach to diagnosis and treatment of postoperative dysphagia allows for prompt intervention and a decrease in morbidity and mortality. Treatment options for dysphagia vary, depending on the etiology. Based on the location and mechanism of dysphagia, options include stenting, dilation and surgical revision. Early treatment of dysphagia after esophagectomy can lessen the morbidity from this complication and improve quality of life.
