SummaryWe investigated whether adding gastropexy to sleeve gastrectomy (SG) reduced gastroesophageal reflux disease (GERD) in patients operated for severe obesity, assessed mainly by use of anti‐reflux medication (ARM) and second operations due to GERD worsening. In a prospective non‐randomized study, patients undergoing SG at two Norwegian hospitals were included from 2011 to 2015 and followed for 7 years. GERD was defined by regular use of ARM, and epigastric pain and heartburn were measured by the Rome II questionnaire. Gastropexy was done by suturing the gastrocolic ligament to the staple line. Patients undergoing SG only, mainly before gastropexia was introduced in 2013, were compared to those with additional gastropexy from 2013 onwards. Of 376 included patients (75% females, mean age 42.6 years and BMI 42.9 kg/m²), 350 (93%) and 232 (62%) were available for evaluation after 1 and 7 years, respectively. Baseline characteristics in the no‐gastropexy (n = 235) and gastropexy groups (n = 141) were similar. In patients without ARM use before surgery, the use increased and in those that used ARM at baseline, the proportion decreased, with no difference in the no‐gastropexy and gastropexy groups. With a combined endpoint of ARM use and/or second operation for GERD, there was no difference during follow‐up between the two groups. With time, adding gastropexy did not reduce symptoms of GERD significantly. In this population, adding gastropexy to SG did not reduce use of ARM and/or second operation for uncontrolled GERD, epigastric pain or heartburn during the first 7 postoperative years.
