Reflux recurrence after laparoscopic antireflux surgery has not been assessed in a long-term population-based study of unselected patients. </p> </div><div class="section"> <a class="named-anchor" id="ab-joi170092-5"> <!-- named anchor --> </a> <h5 class="section-title" id="d15216422e305">Objectives</h5> <p id="d15216422e307">To determine the risk of reflux recurrence after laparoscopic antireflux surgery and to identify risk factors for recurrence. </p> </div><div class="section"> <a class="named-anchor" id="ab-joi170092-6"> <!-- named anchor --> </a> <h5 class="section-title" id="d15216422e310">Design and Setting</h5> <p id="d15216422e312">Nationwide population-based retrospective cohort study in Sweden between January 1, 2005, and December 31, 2014, based on all Swedish health care and including 2655 patients who underwent laparoscopic antireflux surgery according to the Swedish Patient Registry. Their records were linked to the Swedish Causes of Death Registry and Prescribed Drug Registry. </p> </div><div class="section"> <a class="named-anchor" id="ab-joi170092-7"> <!-- named anchor --> </a> <h5 class="section-title" id="d15216422e315">Exposures</h5> <p id="d15216422e317">Primary laparoscopic antireflux surgery due to gastroesophageal reflux disease in adults (&gt;18 years). </p> </div><div class="section"> <a class="named-anchor" id="ab-joi170092-8"> <!-- named anchor --> </a> <h5 class="section-title" id="d15216422e320">Main Outcomes and Measures</h5> <p id="d15216422e322">The outcome was recurrence of reflux, defined as use of antireflux medication (proton pump inhibitors or histamine ₂ receptor antagonists for &gt;6 months) or secondary antireflux surgery.

Risk factors for reflux recurrence included female sex (hazard ratio [HR], 1.57 [95% CI, 1.29-1.90]; 286 of 1301 women [22.0%] and 184 of 1354 men [13.6%] had recurrence of reflux), older age (HR, 1.41 [95% CI, 1.10-1.81] for age ≥61 years compared with ≤45 years; recurrence among 156 of 715 patients and 133 of 989 patients, respectively), and comorbidity (HR, 1.36 [95% CI, 1.13-1.65] for Charlson comorbidity index score ≥1 compared with 0; recurrence among 180 of 804 patients and 290 of 1851 patients, respectively). Hospital volume of antireflux surgery was not associated with risk of reflux recurrence (HR, 1.09 [95% CI, 0.77-1.53] for hospital volume ≤24 surgeries compared with ≥76 surgeries; recurrence among 38 of 266 patients [14.3%] and 271 of 1526 patients [17.8%], respectively). </p> </div><div class="section"> <a class="named-anchor" id="ab-joi170092-10"> <!-- named anchor --> </a> <h5 class="section-title" id="d15216422e333">Conclusions and Relevance</h5> <p id="d15216422e335">Among patients who underwent primary laparoscopic antireflux surgery, 17.7% experienced recurrent gastroesophageal reflux requiring long-term medication use or secondary antireflux surgery. Risk factors for recurrence were older age, female sex, and comorbidity. Laparoscopic antireflux surgery was associated with a relatively high rate of recurrent gastroesophageal reflux disease requiring treatment, diminishing some of the benefits of the operation. </p> </div>
