Abstract Background The open Hill repair for gastroesophageal reflux disease and hiatal is remarkably durable, with a median 10-year reoperation rate of only 3% and satisfaction of 93%. No long-term data exist for the laparoscopic Hill repair (LHR). Methods Patients who underwent primary LHR at Swedish Medical Center for reflux and/or hiatal hernia at least 5 years earlier (1992–2010) were identified from an IRB-approved database. There were 727 patients who met inclusion criteria, including 648 undergoing repair for reflux and 79 for paraesophageal hernia. Two questionnaires were administered via mail to evaluate long-term quality of life using validated GERD-HRQL, Swallowing score, and global satisfaction score. Outcomes were defined by GERD-HRQL score, Swallowing score, resumption of proton pump inhibitor (PPI) therapy, need for reoperation, and global satisfaction with overall results. Results Two hundred forty-two patients completed and returned the survey (226 lost to follow-up, 90 deceased, 3 denied undergoing LHR, 166 non-responders), of which 52% were male. The average age at the time of was 49.5 years. Median follow-up was 18.5 years (range 6.2–24.7). The average GERD-HRQL score (7.1) and the average Swallowing score (39.9) both indicated excellent symptomatic outcomes. 30% of patients are using daily PPIs. 24 patients (9.9%) required reoperation for failure during the follow-up period, 21 in the reflux group and 3 in the paraesophageal hernia group. Overall, 85% reported good to excellent results, and 76% would recommend the operation. Conclusion LHR shows excellent long-term durability and quality of life similar to the open Hill repair, with 85% good to excellent results at a median follow-up of 19 years and a reoperation rate under 10%. It is surmised that Hill suture fixation of the gastroesophageal junction to the preaortic fascia may confer unique structural integrity compared to other repairs.

More than 2500 LHRs have been performed globally since its introduction in 1992 [4]. Short-term clinical results were reported as good to excellent in 92% at 8 months fol- lowing surgery [5]. The disclosed daily PPI usage ranges from 4 to 15% at 1-year follow-up [5–7]. A 15-month follow- up analysis that applied the same quality of life assessments exhibited an average 8.1 GERD-HRQL score and 38.1 Swal- lowing score [7]. The Hill repair is unique among antireflux procedures in securing the GEJ itself to the preaortic fascia intra- abdominally. The resistance to axial forces by GEJ fixation potentially reduces herniation [4], the most common cause of failure following Nissen fundoplication. In addition, this firm fixation allows the Hill repair to be utilized in the case of short , typically without the need for Collis Fig. 3 Global satisfaction with overall LHR outcomes of primary gastroplasty [8]. Furthermore, in contrast to LNF, LHR does patients not significantly raise lower esophageal sphincter pressure, being based instead on reconstruction of the gastroesopha- geal valve, thus making it applicable for patients with poor esophageal motility [9]. Short-term results with the LHR are equivalent to the laparoscopic Nissen fundoplication (LNF) in clinical and objective parameters measuring clinical suc- cess and repair failure at 1-year follow-up [6], but they have not been compared long-term. The structural components of Hill repair may have par- ticular durability. In a large multi-institution retrospective study of over 1100 patients undergoing open Hill repair with a 10-year mean follow-up, 91% rated their outcomes as good to excellent, with a reoperation rate of 1.9 and a 23% resumption of anti-secretory medication [1]. Furthermore, the addition of Hill sutures to laparoscopic Nissen repair for paraesophageal hernia achieved a substantial reduction in 60-month anatomic recurrences from 45 to 5% [10], perhaps due to fixation of the GEJ to the preaortic fascia, which may Fig. 4 Patient’s likelihood of recommending LHR to family members unload axial stress from the fundoplication. The strength suffering from comparable condition of the Hill repair may come at a small price, as the dilation rate of 16% is a bit high and likely reflects the “non-floppy” smaller diameter calibration of the repair over a 45–48 Fr frequent dysphagia symptom incidences of avoiding food bougie. (p = 0.01) and eating slower (p = 0.01). The higher failure rate in this study compared to open Hill repair is not readily explained, but likely in part reflects the early learning curve transition from open to laparoscopic repair.
