Paraesophageal herniation of the stomach is a rare complication following l
aparoscopic Nissen fundoplication. We retrospectively reviewed our experien
ce with 720 patients undergoing laparoscopic Nissen fundoplications. Seven
patients were found to have postoperative paraesophageal hernias requiring
reoperation. The clinical presentation, diagnostic workup, operative treatm
ent, and outcome were evaluated. There were no deaths or procedure-related
complications. Clinical presentation was recurrent dysphagia in four, nonsp
ecific abdominal symptoms in one, and acute abdomen in one. One additional
patient was asymptomatic. Preoperatively the correct diagnosis was able to
be confirmed in four of six patients by barium esophagogram Four patients u
nderwent successful laparoscopic repair. Two patients had a thoracotomy inc
luding one conversion from laparoscopy to thoracotomy. One patient had a la
parotomy to reduce an intrathoracic gastric volvulus. At a mean follow-up o
f 2.5 months no patient had further complications. Paraesophageal herniatio
n is a rare complication following laparoscopic Nissen fundoplication and a
definitive diagnosis is often difficult to establish. Early dysphagia afte
r surgery should alert the surgeon to this complication. Redo laparoscopic
surgery is feasible but an open procedure may be necessary.
