Long-term clinical evaluation of laparoscopic management of large hiatal hernias

Large hiatal hernias (LHH) account for 5-10% of all hiatal hernias. Surgery of LHH should be associated with low rates of postoperative complications and recurrences, to guarantee a favorable quality of life (QoL). Data on long-term results of laparoscopic repair of LHH are lacking. The objective of our study is to evaluate the long-term clinical outcomes of laparoscopic LHH management in a high-volume experienced center.

Patients who had undergone elective laparoscopic repair of LHH between January 1992 and December 2008 at the Center of Minimally Invasive Surgery of the Department of Surgical Sciences, University of Turin, Italy were included. Preoperative and intraoperative data were collected from patients' charts. Patients were clinically evaluated at long-term postoperative follow-up to assess control of symptoms, degree of satisfaction with surgery, and QoL.

At mean follow-up of 240 months (range 168-348), 81 patients were available for clinical evaluation. Severe heartburn was reported by six patients (7.4%), while severe post-prandial epigastric pain by three (3.7%). Recurrent coughing episodes were described by six patients (7.4%), while occasional mild episodes of transient dysphagia by 13 (16%). No gas bloat detected. Proton Pump Inhibitors were taken by 22 patients (27.2%) to control symptoms. The Modified Italian Gastroesophageal Reflux Disease-Health Related Quality of Life (MI-GERD-HRQL) score decreased significantly from 40 to 7 (P<0.0001) postoperatively. Satisfaction was achieved in 76 patients (93.8%) with an average satisfaction index of 8.6 (IQR 8-10).

Laparoscopic LHH repair is effective when performed in a specialized center, with long-lasting significant improvements of symptoms and QoL.
