Treatment of giant paraesophageal hernia: pro laparoscopic approach

PurposeGiant paraesophageal hernias (GPEH) are relatively uncommon and account for less than 5% of all primary hiatal hernias. Giant Secondary GPEH can be observed after surgery involving hiatal orifice opening, such as esophagectomy, antireflux surgery, and hiatal hernia repair. Surgical treatment is challenging, and there are still residual controversies regarding the laparoscopic approach, even though a reduced morbidity and mortality, as well as a shorter hospital stay have been demonstrated.MethodsA Pubmed electronic search of the literature including articles published between 1992 and 2016 was conducted using the following key words: hiatal hernia, paraesophageal hernias, mesh, laparoscopy, intrathoracic stomach, gastric volvulus, diaphragmatic hernia.ResultsGiven the risks of non-operative management, GPEH surgical repair is indicated in symptomatic patients. Technical steps for primary hernia repair include hernia reduction and sac excision, correct repositioning of the gastroesophageal junction, crural repair, and fundoplication. For secondary hernias, the surgical technique varies according to hernia type and components and according to the approach used during the first surgery. There is an ongoing debate regarding the best and safest method to close the hiatal orifice. The laparoscopic approach has demonstrated a lower postoperative morbidity and mortality, and a shorter hospital stay as compared to the open approach. A high recurrence rate has been reported for primary GPEH repair. However, recent studies suggest that recurrence does not reduce symptomatic outcomes.ConclusionsThe laparoscopic treatment of primary and secondary GPEH is safe and feasible in elective and emergency settings, especially in high-volume centers. The procedure is still challenging. The main steps are well defined. However, there is still room for improvement to lower the recurrence rate.
