Lack of Correlation Between Subjective and Objective Measures of Gastroesophageal Reflux Disease: Call for a Novel Validated Assessment Tool

Use of Preoperative Endoscopic Capsule-Based pH Testing Before Bariatric Surgery

BACKGROUND

Vertical sleeve gastrectomy is the most performed bariatric operation in the US; however, a significant number of patients suffer from persistent or new-onset reflux. No consensus for objective preoperative evaluation in these patients exists. We compared capsule-based pH testing vs GERD symptom scoring to determine extent of preoperative GERD to aid in procedure selection for bariatric surgery.

STUDY DESIGN

An IRB-approved retrospective review of consecutive patients at a single institution was performed from April 2021 to December 2022. During initial consultation for bariatric surgery, a validated GERD symptom subjective survey was administered. All patients demonstrating interest in sleeve gastrectomy or had a history of reflux underwent upper endoscopy with capsule-based pH testing.

RESULTS

Sixty-two patients underwent preoperative endoscopy with capsule-based pH testing and completed GERD symptom assessment survey(s). Median BMI was 43.4 kg/m 2 and 66.1% of patients were not taking a proton-pump inhibitor before performance of pH testing. There was negligible linear association between the objective DeMeester score obtained by capsule-based pH probe and GERD symptom survey scores. Median GERD symptom survey scores did not differ between patients with and without a diagnosis of GERD based on pH testing (all p values >0.11).

CONCLUSIONS

An objective method for identifying severe GERD in the preoperative assessment may aid in the decision tree for procedure selection and informed consent process. Patients with significant preoperative GERD may be at higher risk for future GERD-related sleeve complications. Capsule-based pH testing may prove to be superior to subjective symptom scoring systems in this patient population.

Severe Reflux and Symptoms of Anxiety and Depression After Esophageal Cancer Surgery

BACKGROUND

Approximately 30% of patients suffer from severe reflux after surgery for esophageal cancer, which may serve as a continuous reminder of the cancer and catalyze fear of recurrence.

OBJECTIVE

The aim of this study was to investigate the association between severe reflux and symptoms of anxiety and depression after esophageal cancer surgery.

METHODS

This was a nationwide prospective cohort study including all Swedish patients who underwent esophageal cancer surgery between 2013 and 2018. Patients reported reflux on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire module for gastroesophageal symptoms and psychological distress on the Hospital Anxiety and Depression Scale at 1 and 2 years after surgery. Repeated-measures logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for age, sex, comorbidity, body mass index, TNM classification, neoadjuvant therapy, surgery type, postoperative complications, antireflux medication, and elevated headrest at night.

RESULTS

Among 154 included patients, 43 (28%) and 37 (24%) reported severe reflux 1 and 2 years after surgery, respectively. No association between severe reflux and anxiety (OR, 2.1; 95% CI, 0.7-6.3) or depression (OR, 1.2; 95% CI, 0.3-4.6) was found 1 year after surgery. After 2 years, there was still no association between severe reflux and anxiety (OR, 0.9; 95% CI, 0.3-2.8) or depression (OR, 1.2; 95% CI, 0.5-3.3).

CONCLUSIONS

Findings suggest that severe reflux is not associated with anxiety or depression after esophageal cancer surgery.

IMPLICATIONS FOR PRACTICE

For esophageal cancer survivors, other factors than severe reflux may be more important for the psychological recovery.
