BackgroundData are lacking on trends in bariatric surgery and the frequency of incidental findings in Saudi Arabia.ObjectiveReport on trends in bariatric surgery as well as our experience in incidental findings along with a literature review (mainly on gastrointestinal stromal tumor).DesignRetrospective chart and literature review.SettingsAcademic tertiary care center.Patients And MethodsWe conducted a retrospective study at King Khalid University Hospital and analyzed the data collected from 2009 to 2019. We collected data on age, body mass index (BMI), H pylori infection, type of bariatric surgery performed, and type and location of incidental findings.Main Outcome MeasuresIncidental findings during or after bariatric surgery (in pathology specimen).Sample Size3052 bariatric surgeries, 46 patients with incidentalomas.ResultsThe mean and standard deviation for the age of the 46 patients with incidentalomas was 42.1 (13.9) years and the mean (SD) preoperative BMI was 43.4 (6.4) kg/m2. Of 3052 bariatric surgeries performed, the most common type was sleeve gastrectomy (93.9%), followed by gastric bypass surgery (4.58%) and gastric banding (1.47%). The total frequency of incidentalomas was 1.5%; 10.8% of patients had gastrointestinal stromal tumors (GIST), with the stomach being the commonest site for incidental findings. Eighty percent of the patients with GIST were positive for H pylori (P=.01 vs negative patients).ConclusionThe number of incidentalomas and other findings were consistent with other reports. All these findings suggest that bariatric surgeons should take special care before, during, and after a laparoscopic operation in obese patients.LimitationsSince this is a single-center, retrospective study, we did not collect data on important variables such as gender, socioeconomic status of the patient, and family history of obesity, and we did not perform a preoperative esophagogastroduodenoscopy.Conflict Of InterestNone.
