“True” parahiatal hernia: a rare entity radiologic presentation and clinical management

Para-oesophageal and parahiatal hernias in an Asian acute care tertiary hospital: an underappreciated surgical condition

“…(11)(12)(13)(14)(15)(16)(17) All the cases reported, including those of the present study, were left parahiatal hernias, suggesting that left parahiatal hernias are more common than right parahiatal hernias. Therefore, it is important to pay attention when dissecting in the region to the left of the diaphragmatic crura during surgery to treat an apparent PEH, so that the possibility of a parahiatal hernia can be excluded.…”

“…In a study conducted by Scheidler et al in a single Western centre, the incidence of parahiatal hernia in their cohort of laparoscopically treated HHs was 0.2% (2/917). (11) Similarly, Palanivelu et al reported a low incidence of parahiatal hernia (0.35%, 4/1,127) in their cohort of HH patients who were laparoscopically treated in a single Asian centre. (13) The unusually high proportion of parahiatal hernias in our hospital (20%, 2/10) might either indicate an underreporting of HHs (thereby leading to the smaller overall number of HHs being treated), or suggest that parahiatal hernia is an underappreciated condition that should be actively excluded in the differential diagnosis during surgical exploration of all PEHs.…”

“…(11)(12)(13)(14)(15)(16)(17) The reported incidence is low, accounting for only 1.6% and 0.35% of all preoperatively diagnosed PEHs in Western and Asian centres, respectively. (11,13) Since the management of parahiatal hernia differs from that of PEH, it is important that these two entities are effectively differentiated. The aim of this study was to present the experience of an Asian acute care tertiary hospital in the management of giant PEHs and parahiatal hernias, in order to enhance the understanding of these rare but important conditions.…”

Laparoscopic repair of secondary parahiatal hernia with incarceration of the stomach: a case report

“…However, parahiatal hernia is extremely rare; the exact incidence of parahiatal hernia is not known. Only a few patients with this condition have been reported so far [1,2,4-6]. Palanivelu et al .…”

“…Although these hernias may arise from both sides of the pneumoenteric recesses, they are usually found on the left side. This may be attributed to the presence of the liver on the right side, leading to protection of the diaphragm on that side [2,4-6]. However, the low incidence of this condition makes it difficult to draw firm conclusions.…”
