Barrett`s Esophagus in Bariatric Surgery: Regression or Progression?

INTRODUCTION: Morbid obesity is well known as a risk factor for gastroesophageal reflux disease (GERD) and its related disorders such as Barrett's esophagus (BE). This study aimed to evaluate the development of BE in patients who underwent bariatric surgery. MATERIALS AND METHODS: Using a single-center prospectively established database of obese patients who underwent bariatric surgery from 01/2012 to 12/2019, we retrospectively compared the preoperative endoscopic findings of BE to those after 1-2 years and 3-5 years following bariatric surgery. The change of BE was detected endoscopically according to Prague classification and histologically according to the British guidelines of detecting columnar epithelium on the distal esophagus. RESULTS: Among 914 obese patients who underwent bariatric surgery and received a preoperative esophagogastroduodenoscopy (EGD), we found 119 patients (13%) with BE. A follow-up EGD was performed in 74 of the BE patients (62.2%). A total of 37 (50%) patients underwent a follow-up EGD after 1-2 years and 45 (60.8%) patients underwent it after 3-5 years. Among many clinical parameters, the surgical procedure was the only significant factor for the change of BE after bariatric surgery (p < 0.05). A regression of BE was found in 19 patients (n = 54, 35%) after laparoscopic Roux-en-Y- gastric bypass (LRYGB). Furthermore, a progression of BE was detected in six patients (n = 20, 30%) after laparoscopic sleeve gastrectomy (LSG). CONCLUSION: RYGB should be considered in obese patients with BE. Detecting BE prior to bariatric surgery may have an impact on decision-making regarding the suitable surgical bariatric procedure.

Cutaneous Hemorrhage Types as Supportive Factors for Predicting Chronic Immune Thrombocytopenia in Children.

Our objective was to assess risk factors for developing chronic immune thrombocytopenia (ITP) in children. The charts of all consecutive children diagnosed with ITP between 2000 and 2015 at a single center were retrospectively reviewed, and clinical characteristics at initial presentation were analyzed. Sixty-two children were included in the study (mean age, 6.15 y); 44 (71%) were found to have acute ITP, and 18 (29%) developed chronic ITP (permanent or relapsing thrombocytopenia >12 mo). In a univariate analysis, cutaneous hemorrhages were observed significantly more in acute patients (90.9%) than in chronic patients (61.1%). Patients who had acute ITP were more likely to present with a combination of petechiae, purpura, and/or ecchymosis (75%) than patients with chronic disease (44.4%, P=0.010). In multivariate analysis, older age increased the risk (odds ratio=1.1; P<0.05) for chronic disease, and manifestations of combination skin hemorrhages (petechiae/purpura/ecchymosis) reduced the risk (odds ratio=0.167; P<0.05). In conclusion, the most important risk factor for chronic disease is older age. Skin hemorrhage types were found to be a supportive factor for the prediction process: the combination of petechia/purpura/ecchymosis was associated with a lower risk for developing chronic disease compared with petechiae alone. Future studies should assess the prognostic value of skin hemorrhage types that are a simple way to predict the course of ITP in children.
