Simple suture or prosthesis hiatal closure in laparoscopic repair of paraesophageal hernia: a retrospective cohort study.

Laparoscopic repair of paraesophageal hernia (PEH) involves removal of the hernia sac, cruroplasty, and fundoplication. Mesh application to cruroplasty seems to reduce hernia recurrence rate, but may be associated with dysphagia. The aim of the study was to review the clinical and laboratory outcomes of a series of patients with PEH after laparoscopic repair. Patients with PEH, who had laparoscopic repair and 1-year postoperative follow-up, were included in the study. Pre- and postoperative testing included symptom questionnaires, barium esophagogram, pH-monitoring, barium swallow testing. In the first half cases, suturing of large hernia gaps was reinforced with prosthesis (PR), whereas in the second half only suture cruroplasty (SC) was performed. Sixty-eight patients (36 male) with PEH were included in the study. There were no conversions to open. Postoperatively, dysphagia grading was significantly correlated to esophageal transit time (P < 0.001). There were seven recurrences; one paraesophageal and six wrap migrations. Also, four cases with stenosis were identified all in the PR group. Dysphagia was more common (P= 0.05) and esophageal transit more delayed (P= 0.034) after PR than after SC. Two revisions, one for esophageal stenosis and one for recurrent PEH, derived from the SC group. Reflux was more common after Toupet fundoplication than after Nissen fundoplication (NF) (P= 0.031) in patients with impaired esophageal motility. Laparoscopic repair of PEH with SC is associated with satisfactory clinical outcomes and low rate of wrap migration, at least similar to PR hiatal repair. NF is effective as an antireflux procedure in all cases.
