- Long-term follow-up after transoral outlet reduction following Roux-en-Y gastric bypass: Back to stage 0?(2023) BRUNALDI, Vitor Ottoboni; OLIVEIRA, Guilherme Henrique Peixoto de; KERBAGE, Anthony; RIBAS, Pedro Henrique; NUNES, Felipe; FARIA, Galileu; MOURA, Diogo de; RICCIOPPO, Daniel; SANTO, Marco; MOURA, Eduardo deBackground and study aims Significant weight regain affects up to one-third of patients after Roux-en-Y gastric bypass (RYGB) and demands treatment. Transoral outlet reduction (TORe) with argon plasma coagulation (APC) alone or APC plus full-thickness suturing TORe (APC-FTS) is effective in the short term. However, no study has investigated the course of gastrojejunostomy (GJ) or quality of life (QOL) data after the first post-procedure year.Patients and methods Patients eligible for a 36-month follow-up visit after TORe underwent upper gastrointestinal endoscopy with measurement of the GJ and answered QOL questionnaires (RAND-36). The primary aim was to evaluate the long-term outcomes of TORe, including weight loss, QOL, and GJ anastomosis (GJA) size. Comparisons between APC and APC-FTS TORe were a secondary aim.Results Among 39 eligible patients, 29 returned for the 3-year follow-up visit. There were no significant differences in demographics between APC and APC-FTS TORe groups. At 3 years, patients from both groups regained all the weight lost at 12 months, and the GJ diameter was similar to the pre-procedure assessment. As to QOL, most improvements seen at 12 months were lost at 3 years, returning to pre-procedure levels. Only the energy/fatigue domain improvement was kept between the 1- and 3-year visits.Conclusions Obesity is a chronic relapsing disease. Most effects of TORe are lost at 3 years, and redilation of the GJA occurs. Therefore, TORe should be considered iterative rather than a one-off procedure.

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.

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.
