BackgroundPrior studies have demonstrated an increase in gastroesophageal reflux after laparoscopic sleeve gastrectomy (LSG). However, it is unknown whether symptom severity varies or if outcomes are surgeon-specific.MethodsA validated reflux symptom survey was obtained at baseline and at 1 year after primary LSG on 7358 patients participating in a state-wide quality improvement collaborative between 2013 and 2018. Patients with worsening symptoms after surgery were divided into terciles based on the degree of increase in survey score (0 = no symptoms, 50 = max symptoms). Surgeon-level data was obtained on 52 bariatric surgeons performing at least 25 LSG cases/year during the study period. Surgeon characteristics, operative experience, and risk-adjusted 30-day complication rates were compared between surgeons in the highest tercile for moderate worsening of symptoms vs those in the lowest.ResultsA total of 2294 (31.2%) patients had worsening symptoms of reflux after sleeve gastrectomy. Overall mean increase in severity score was 6.11 (range 1 to 48) and patients with minimal, mild, and moderate symptoms had a mean increase of 1.4, 4.2, and 13.8, respectively. There were no significant differences in surgeon-specific characteristics when comparing surgeons in the highest tercile for moderate worsening of symptoms (44.7% of patients) vs those in the lowest tercile (18.7% of patients). In addition, there were no significant differences in risk-adjusted rates of overall complications (3.70% vs. 4.33%, p = 0.686), endoscopic dilations (2.83% vs. 1.91%, p = 0.417), or concurrent hiatal hernia repair (34.3% vs. 27.0%, p = 0.415) between surgeons in the highest and lowest terciles.ConclusionsWe found that 1/3 of patients had worsening symptoms of reflux after LSG and that severity of symptoms varied. Surgeons with the highest rates of worsening reflux had similar operative experience and complication rates than those with the lowest. Further assessment of operative technique and skill may be informative.
