Prevalence and Predictors of Gastroesophageal Reflux Disease After Laparoscopic Sleeve Gastrectomy.

BACKGROUND AND AIMS: Laparoscopic sleeve gastrectomy (LSG) might be associated with a new onset or worsening of gastroesophageal reflux disease (GERD). We aim to evaluate the prevalence of post-LSG GERD symptoms and its predictors. METHODS: We included patients who underwent primary LSG at a university hospital from 2009 to 2015. We used the GERD-Health-Related Quality of Life (GERD-HRQL) questionnaire and included questions regarding regurgitation to evaluate symptoms before and after LSG; each item was scored from 1 to 5 based on the symptom severity. RESULTS: A total of 213 patients (mean age, 36.08 ± 10.22 years; 48.36% were men) were included. The mean preoperative body mass index (BMI) was 47.84 kg/m2, mean percent total weight loss was 37.99% (95% CI, 36.64 to 39.34), mean percent excess weight loss was 84.14% (95% CI, 80.91 to 87.36), and the mean percent excess BMI loss was 84.17% (95% CI, 80.94 to 87.41). The mean heartburn score while standing increased (0.71 vs. 1.09, p < 0.01) as well as the score of heartburn requiring a diet change (0.67 vs. 1.16, p < 0.01) post-LSG. The scores for dysphagia, odynophagia, and regurgitation increased. New-onset heartburn was reported in 47.06% of our cohort. Those with high preoperative BMIs were less likely to develop new-onset or worsening symptoms of GERD (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.95-0.99). More severe heartburn symptoms while standing were associated with higher risks of developing or worsening GERD symptoms (OR, 1.22; 95% CI, 1.01-1.47). None of the other variables could predict the development or worsening of the GERD symptoms. CONCLUSION: Symptoms of heartburn and regurgitation are common after LSG; however, none of the variables preoperatively could strongly predict patients who would develop new onset or experience worsening of symptoms postoperatively.

Use of Self-Expandable Metal Stents in the Treatment of Leaks Complicating Laparoscopic Sleeve Gastrectomy: A Cohort Study.

BACKGROUND: Use of a self-expandable metal stent (SEMS) as an initial intervention for leaks after laparoscopic sleeve gastrectomy (LSG) has increased. We assessed the efficacy and safety of SEMS in the treatment of post-LSG leaks, and the determinants of repeated rounds of stenting. METHODS: A retrospective chart review was conducted at a university hospital in Saudi Arabia. The study included patients who developed leaks after undergoing LSG between October 2011 and April 2016. RESULTS: Sixty-four patients (mean age, 35.69 ± 10.71 years) were included; 55% were males. The mean estimated size of the defect was 1.18 cm; partially covered SEMS and fully covered SEMS were used as the initial stents in 82.81 and 17.19% patients, respectively. One round of stenting was required in most patients (82.81%), two rounds in 10.94%, and three rounds in 6.25%. Clinical success was achieved in 93.75% patients, including 78.13% in the first round, 89.06% by the second round, and 93.75% by the third round. A higher proportion of patients who needed one round of stenting received a partially covered SEMS compared to those who needed two rounds (91.11 vs. 42.86%, p < 0.01). Additionally, the rate of migration in patients who underwent two rounds was higher than that in patients who underwent one round (42.86 vs. 5.26%, p < 0.01) of stenting. CONCLUSION: Repeated stenting for leaks after LSG is an effective and safe intervention. The efficacy of partially covered SEMS appears superior to that of the fully covered SEMS.
