Background:
Post-hepatectomy diaphragmatic hernia is the second most common cause of acquired diaphragmatic hernia. This study aims to review the literature on this complication's incidence, treatment and prognosis.
Methods:
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched PubMed for all studies related to acquired diaphragmatic hernias after hepatectomy.
Results:
We included 28 studies in our final analysis, comprising 11,368 hepatectomies. The incidence of post-hepatectomy diaphragmatic hernia was 0.75% (n = 86). The most frequent type of hepatectomy performed was right hepatectomy (79%, n = 68), and the indications for liver resection were a liver donation for living donor transplantation (n = 40), malignant liver tumors (n = 13), and benign tumors (n = 11). The mean onset between liver resection and the diagnosis of diaphragmatic hernia was 25.7 months (range, 1-72 months), and the hernia was located on the right diaphragm in 77 patients (89.5%). Pain was the most common presenting symptom (n = 52, 60.4%), while six patients were asymptomatic (6.9%). Primary repair by direct suture was the most frequently performed technique (88.3%, n = 76). Six patients experienced recurrence (6.9%), and three died before diaphragmatic hernia repair (3.5%).
Conclusion:
Diaphragmatic hernia is a rare complication occurring mainly after right liver resection. Repair should be performed once detected, given the not-negligible associated mortality in the emergency setting.
