Upper gastrointestinal tract involvement in the management of bariatric patients in the Kingdom of Saudi Arabia

Background

Preoperative esophagogastroduodenoscopy (EGD) may affect the management of bariatric patients although this is not consistent universally. The present prospective study evaluated the effect of preoperative EGD findings in obese Saudi patients, including upper digestive symptoms (UDS) and comorbidities, on their planned surgery.

Methods

From January 2018 to May 2019, we conducted a 4-center retrospective observational study to evaluate the endoscopic findings among Saudi patients aged 18-65 years with a body mass index (BMI) >40 kg/m². Preoperative data included UDS, comorbidities, Helicobacter pylori (H. pylori) infection assessed during a histopathological examination, and EGD findings.

Results

717 patients underwent EGDs, and 432 underwent bariatric surgery. The mean BMI was 44.3±6.3 kg/m², and the mean age was 27.8±11.8 years. The overall UDS prevalence was 49%, with the most frequent being gastroesophageal reflux disease 54% (387/717), followed by dyspepsia 44% (315/717). H. pylori infection was detected in 287/672 (42.4%) patients. The total percentage of patients with normal EGD was 36% (258/717). A delayed bariatric procedure was performed in 15% of the patients for the following reasons: 2.3% had large polyps of >1 cm (either hyperplastic or cystic polyps); 1.62% had esophagitis grade C and D based on the Los Angeles classification; 0.7% had Barrett’s esophagus; and 5.7% had peptic ulcer disease.

Conclusions

Our findings confirmed that obesity carries a profound health burden with a significant impact on health expenditures. Routine preoperative EGD in the obese Saudi population appears to be mandatory to identify factors that may change, delay, or postpone the bariatric procedure.

Effects of the Rome IV Criteria to Functional Dyspepsia Symptoms in Saudi Arabia: Epidemiology and Clinical Practice

Background/Aims

Limited data is available in Saudi Arabia (SA) regarding the prevalence of functional dyspepsia (FD) symptoms and its subtypes, as defined by the ROME IV criteria. This study evaluated the burden of self-reported FD symptoms in the adult general population of SA and the current clinical practices.

Methods

A web-based national cross-sectional health survey of the general population of SA was conducted using the Rome IV Diagnostic Questionnaire for Functional Gastrointestinal Disorders in Adults with additional questions on the presence of symptoms compatible with functional heartburn (FH) and irritable bowel syndrome (IBS). The quality of life and somatization questionnaires were also included.

Results

Overall, 3,114 adults completed the questionnaire, but 303 (9.7%) were excluded due to inconsistent responses. Of the 2,811 consistent responders, 532 (18.3%) fulfilled the Rome IV criteria for FD symptoms. These were distributed into the FD subtypes as follows: 208 (7.4%) had postprandial distress syndrome, 228 (8.1%) had epigastric pain syndrome, and 96 (3.4%) had the overlapping variant. IBS-like symptoms were reported in 232 (44%) and FH in 102 (19%) 19% (102) of the subjects with functional dyspepsia. H. pylori-associated dyspepsia was reported by 25% (87/348). High somatization, lower quality of life scores, younger age, and female sex were associated more with the FD symptoms participants than those without. Approximately 1/5 respondents used over-the-counter medications to relieve the FD symptoms.

Conclusions

In this population-based survey, FD affected almost 1/5 of the responding adult population in SA, which was less than previously reported.
