    Impact of Endoscopic Sleeve Gastroplasty in Non-alcoholic Fatty Liver Disease: a Systematic Review and Meta-analysis
    (2023) NUNES, Beanie Conceicao Medeiros; MOURA, Diogo Turiani Hourneaux de; KUM, Angelo So Taa; OLIVEIRA, Guilherme Henrique Peixoto de; HIRSCH, Bruno Salomao; RIBEIRO, Igor Braga; GOMES, Igor Logetto Caetite; OLIVEIRA, Claudia Pinto Marques de; MAHMOOD, Sultan; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide. Endoscopic sleeve gastroplasty (ESG) has proven to be feasible, safe, and effective in the management of obesity. We performed the first systematic review and meta-analysis evaluating NAFLD and other metabolic parameters 12 months post-ESG. Four observational studies with a total of 175 patients were included. The results showed a significant (p < 0.05) reduction of 4.85 in hepatic steatosis index (95% CI - 6.02, - 3.67), 0.5 in NAFLD fibrosis score (95% CI - 0.80, - 0.19), 6.32 U/l in ALT (95% CI - 9.52, - 3.11), 17.28% in TWL (95% CI - 18.24, - 16.31), 6.31 kg/m(2) in BMI (95% CI - 8.11, - 4.52), 47.97% in EWL (95% CI - 49.10, - 46.84), and 0.51% in HbA1c (95% CI - 0.90, - 0.12). ESG improves liver parameters, provides weight loss, and reduces HbA1c levels in patients suffering from NAFLD.

    Endoscopic Ultrasound View of Pneumatosis Cystoides Intestinalis
    (2023) YVAMOTO, Erika Yuki; CHENG, Spencer; OLIVEIRA, Guilherme Henrique Peixoto de; SASSO, Joao Guilherme Ribeiro Jordao; BOGHOSSIAN, Mateus Bond; MINATA, Mauricio Kazuyoshi; RIBEIRO, Igor Braga; MOURA, Eduardo Guimaraes Hourneaux de
    Pneumatosis cystoid intestinalis (PCI) is a rare condition, with a worldwide incidence of 0.3-1.2%. PCI is classified into primary (idiopathic) and secondary forms, with 15% and 85% of presentations, respectively. This pathology was associated with a wide variety of underlining etiologies to explain the abnormal accumulation of gas within the submucosa (69.9%), subserosa (25.5%), or both layers (4.6%). Many patients endure misdiagnosis, mistreatment, or even inadequate surgical exploration. In this case, a patient presented acute diverticulitis, after treatment, a control colonoscopy was performed that found multiple rounds and elevated lesions. To further study the subepithelial lesion (SEL), a colorectal endoscopic ultrasound (EUS) was performed with an overtube in the same procedure. For safe insertion of the curvilinear array EUS, an overtube with colonoscopy was positioned through the sigmoid as described by Cheng et al. The EUS evaluation evidenced air reverberation in the submucosal layer. The pathological analysis was consistent with PCI's diagnosis. The diagnosis of PCI is usually made by colonoscopy (51.9%), surgery (40.6%), and radiological findings (10.9%). Although the diagnosis can be made by radiological studies, a colorectal EUS and colonoscopy can be made in the same section without radiation and with high precision. As it is a rare disease, there are not enough studies to define the best approach, although colorectal EUS should be preferred for a reliable diagnosis.
