Diaphragmatic Hernia Repair After Esophagectomy: Technical Report and Lessons After a Series of Cases.

Introduction: Diaphragmatic hernia (DH) repair after esophagectomy is infrequent and technically challenging. Such hernias are mostly asymptomatic and have an estimated incidence of around 2.5%. Controversy continues over suture versus mesh cruroplasty. This article reports a series of cases and a description of the technique, showing this type of procedure being performed in the medical literature and its results. Methods: A DH was diagnosed, and repair was performed in eight out of 328 esophagectomies. All of them were performed through the following steps: (1) Pulling the hernia content down properly without handling the intestinal segment directly to not promote serosal lesions; (2) Lysis of adhesions-this should be done close to the diaphragmatic pillar, with precaution toward the vessels running in the epiplon and near the greater gastric curvature; and (3) Closure of the diaphragmatic hiatus achieved with anterior and posterior sutures. Mesh repair was performed across the DH defects that measured more than 5.5 cm. Results: The patients constituted five men (62.5%) with a mean age of 61.6 years. The main DH-related symptom was abdominal pain, reported by four patients (50%). The other symptoms mentioned were dyspnea (37.5%), thoracic pain (25%), and dysphagia (25%). The mean hospitalization period was 17.5 days and was related to the restoration of the respiratory function. Most of the DH repairs were performed by adopting a laparoscopic approach. Conclusions: DH is a rare complication following esophagectomy with most of the symptomatic manifestations. However, its repair is feasible and safe, with low morbidity (only respiratory complications) and no mortality.
