Abstract
Diaphragmatic transposition of intestinal organs is a major complication after esophagectomy and can be associated with significant morbidity and mortality. This study aims of to analyze a large series of patients with this condition in a single high-volume center for esophageal surgery and to suggest a novel treatment algorithm. Patients who received surgery for postesophagectomy diaphragmatic herniation between October 2003 and December 2017 were included. Retrospective analysis of demographic, clinical and surgical data was performed. Outcomes of measure were initial clinical presentation, postoperative complications, in-hospital mortality and herniation recurrence. A total of 39 patients who had surgery for postesophagectomy diaphragmatic herniation were identified. Diaphragmatic herniation occurred after a median time of 259 days following esophagectomy with the highest prevalence between 1 and 12 months. A total of 84.6% of the patients had neoadjuvant radiochemotherapy prior to esophagectomy. The predominantly effected organ was the transverse colon (87.2%) prolapsing into the left hemithorax (81.6%). A total of 20 patients required emergency surgery. Surgery always consisted of reposition of the intestinal organs and closure of the hiatal orifice; a laparoscopic approach was used in 25.6%. Major complications (Dindo–Clavien ≥ IIIb) were observed in 35.9%, hospital mortality rate was 7.7%. Three patients developed recurrent diaphragmatic herniation during follow-up. Postesophagectomy diaphragmatic herniation is a functional complication of the late postoperative course and predominantly occurs in patients with locally advanced adenocarcinoma having chemoradiation before Ivor–Lewis esophagectomy. Due to a high rate of emergency surgery with life-threatening complications not a ‘wait-and-see’ strategy but early surgical repair may be indicated.Keywords
