Diaphragmatic hernia following esophagectomy for esophageal cancer: A systematic review

Abstract

Purpose: Diaphragmatic hernia following an esophagectomy for esophageal cancer (EC) can be both an early and late complication. The esophageal hiatus within the diaphragm is disrupted during the operation. However, the incidence of Post-Esophagectomy Diaphragmatic Hernia (PEDH) is unknown. PEDH can be life-threatening and surgical treatment is challenging. However, all PEDH do not require surgery. The rate of EC diagnosis is rising. Therefore, esophageal surgery, particularly esophagectomy, is gradually increasing. Undoubtedly, the numbers of PEDH increase as well.

Methods: This review describes the presentation and diagnosis of PEDH after surgery for esophageal malignancy, as well as the management options for PEDH.

Results: Fifteen papers regarding PEDH have been published. There are many different surgical approaches to complete an esophagectomy, while there are different approaches to repair PEDH.

Conclusion: Upper GI surgeons need to have an index of suspicion for PEDH. They must investigate and operate these patients if this complication develops, since an immediate surgery has a high mortality and poor outcome.
