摘要
BACKGROUND Parahiatal hernias(PHHs)are rare occurring disease,with a reported incidence of 0.2%-0.35%in patients undergoing surgery for hiatal hernia.We found only a handful of cases of primary PHHs in the literature.The aim of this paper is to present a case of a primary PHH and perform a systematic review of the literature.CASE SUMMARY We report the case of a 60-year-old Caucasian woman with no history of thoracoabdominal surgery or trauma,which accused epigastric pain,starting 2 years prior,pseudo-angina and bloating.Based on imagistic findings the patient was diagnosed with a PHH and an associated type I hiatal hernia.Patient underwent laparoscopic surgery and we found an opening in the diaphragm of 7 cm diameter,lateral to the left crus,through which 40%-50% of the stomach had herniated in the thorax,and a small sliding hiatal hernia with an anatomically intact hiatal orifice but slightly enlarged.We performed closure of the defect,suture hiatoplasty and a“floppy”Nissen fundoplication.Postoperative outcome was uneventful,with the patient discharged on the fifth postoperative day.We performed a review of the literature and identified eight articles regarding primary PHH.All data was compiled into one tabled and analyzed.CONCLUSION Primary PHHs are rare entities,with similar clinical and imagistic findings with paraesophageal hernias.Treatment usually includes laparoscopic approach with closure of the defect and the esophageal hiatus should be dissected and analyzed.Postoperative outcome is favorable in all cases reviewed and no recurrence is cited in the literature.
