GERD-screening before bariatric surgery: the predictive value of the GERD-HRQL questionnaire score compared with preoperative EGD findings.

BACKGROUND: There is an ongoing debate on how to best identify patients with gastroesophageal reflux disease (GERD) before bariatric surgery. The value of routine preoperative esophagogastroduodenoscopy (EGD) is questioned, and patient reported symptoms are commonly used for screening. The goal of this study is to determine if patient reported symptoms using a validated questionnaire correlate with preoperative EGD findings. METHODOLOGY: A prospective cohort study at a single institution was performed. Patients undergoing bariatric surgery between December 2020 and March 2023 were required to report symptoms of reflux by completing a preoperative GERD. Health-Related Quality of Life (GERD-HRQL) questionnaire and undergo a mandatory preoperative screening EGD. Patients were stratified into two cohorts: (group A) asymptomatic (score = 0) and (group B) symptomatic (score > 0). Statistical analysis was conducted using Pearson's chi-squared test and Wilcoxon rank-sum test in RStudio version 4.2.2. The predictive value of the GERD-HRQL score was analyzed using Areas Under the Curve (AUC; AUC = 0.5 not predictive, 0.5 < AUC ≥ 6 poor prediction & AUC > 0.9 excellent prediction) calculated from Receiver Operating Characteristic (ROC) curves. RESULTS: 200 patients were included; median age was 42.0 years (IQR 36.0 to 49.2). There were 79 patients (39.5%) in Group A and 121 patients (60.5%) in Group B. There was no difference in the frequency esophagitis (27.8% vs 32.2%, p = 0.61) or hiatal hernias (49.4% vs 47.1%, p = 0. 867) between group A and group B, respectively. ROC analysis revealed that the total GERD HRQL scores, heartburn only scores and regurgitation only scores, were poor predictors of esophagitis found on EGD (AUC 0.52, 0.53, 0.52), respectively. In asymptomatic patients, higher BMI was significantly associated with esophagitis (OR 1.15, 95% CI 1.06-1.27, p = 0.002). CONCLUSION: Symptoms, identified through the GERD-HRQL questionnaire, are a poor indicator of esophagitis or its severity in patients undergoing workup for bariatric surgery. Therefore, liberal screening upper endoscopy is recommended for pre-bariatric surgery patients to guide appropriate procedure selection.

Somatization in the conceptualization of sickle cell disease.

The unpredictable nature of sickle cell disease (SCD) and its social and environmental consequences can produce an unhealthy and almost exclusive focus on physical functioning. At the upper range of this focus on health concerns is somatization. In the current study, using 156 adult patients (55.13% female, 86) with SCD, mean age 35.59 +/- 12.73, we explored the relationship of somatization to pain. We found somatization to be predictive of pain severity and current pain intensity as well as a range of averaged indices of pain over time (p < .0001). We further found somatization to be predictive of a range of negative psychological experiences to include depression, anxiety, and hostility (p < .0001). We interpret these data to suggest that patients with SCD who have a propensity to focus exclusively on their health or are more sensitive to minor changes in their health status (somatization) may also be more likely to report greater concerns about their health and higher ratings of pain.
