• Patientsarediagnosedbyendoscopy,bariumswallow,esophagealmanometryandhigh-resolutionmanometry(HRM)postGERDsymptoms.ManystudiesarefavoringHRMwithrulingoutthediagnosisofHH(Khajanchee,Cassera,Swanstrom,&Dunst,2013).
• HRMishighlysensitiveandspecificforhiatalherniadetection,exceedingthesensitivityofendoscopyorradiographyalone.HRMsensitivitywas92%andthespecificityof95%(Weijenborg,VanHoeij,Smout,&Bredenoord,2015).
• Educationiskey!ManagementofHHisverysimilartoGERDmanagement.Somethingsnursescanteachtheirpatientsare:
• Avoidingcertainfoodssuchascoffee,alcohol,chocolate,fattyandacidicmeals(Nwokediuko,2012).
• Eatmealsatleast3-4hrsbeforelyingdown• Keepingtheheadofbedhigherthan6inches• Avoidtightclothingthatcancauseincreasedpressurein
theabdomenarea• Losingweight• (ClevelandClinic,2015)
• SymptomaticHHshouldberepairedbyalaparoscopicapproach(Berselli etal.,2015).
• Itiscontroversialwhethertohaveanopenprocedureorlaparoscopicapproach,astudyshowedtheuseofanabsorbablesyntheticmeshwithalaparoscopicapproachisrelatedtolowreoccurrencerates(Berselli etal.,2015).
• Lowmorbidityandincreasedpatientsatisfactionisrelatedtothelaparoscopicapproachwhencomparedtoanopenapproach(Bankietal.,2016).
• Beforesurgeryisconsidereddoctorslookatwhetherthepatienthasfailedmedicalmanagement(Tatarianetal.,2016).Medicationsincludeantacids,protonpumpinhibitors(PPI),andhistamine2receptorantagonists(H2RA)(Nwokediuko,2012).
