Clinical outcomes of anti-reflux mucosal ablation for gastroesophageal reflux disease: An international bi-institutional study.

BACKGROUND AND AIM: Anti-reflux mucosal ablation (ARMA) is an emerging endoscopic treatment aimed at enhancing the gastroesophageal junction flap valve. This study aimed to evaluate its feasibility, effectiveness, and safety. METHODS: Between May 2018 and December 2022, patients with gastroesophageal reflux disease (GERD) symptoms refractory to acid suppression medications or those dependent on such medications were enrolled for ARMA. This retrospective analysis utilized prospectively collected data from an international bi-center study. GERD questionnaire, upper endoscopy, and 24-h pH monitoring were conducted at 2-6 months and 12 months post-ARMA. Clinical success was defined as a > 50% reduction in a validated GERD questionnaire. RESULTS: A total of 68 patients underwent ARMA. Definitive GERD was diagnosed in 44 (64.7%) patients, while 24 (35.3%) exhibited reflux hypersensitivity. Clinical success rates at 2-6 months and 1 year post-ARMA were 60% (39/65) and 70% (21/30), respectively. The median GERD-health-related quality of life score significantly improved from 26 to 11 at 2-6 months (P < 0.001). Among the 51 patients (71.8%) who underwent 24-h pH monitoring, the median acid exposure time decreased from 5.3% to 0.7% (P = 0.003), accompanied by a significant reduction in esophagitis rates (P < 0.001). Multivariate analysis did not identify predictors of short-term success. Nine (13.2%) patients experienced transient stenosis requiring balloon dilation. CONCLUSIONS: ARMA demonstrates both technical feasibility and reproducibility as a safe procedure that effectively ameliorates GERD symptoms in approximately two-thirds of patients during short-term follow up. Both reflux hypersensitivity and confirmed GERD patients, regardless of their response to acid suppression medication, may be suitable candidates.

Lumen-apposing metal stents versus biliary fully-covered metal stents for EUS-guided drainage of pancreatic fluid collections: a case control study: Meeting presentations: European Society of Gastrointestinal Endoscopy ESGE Days 2018.

Background and study aims Endoscopic ultrasound (EUS)-guided drainage has become first-line treatment for pancreatic fluid collections (PFC). The aim of this study was to compare the effectiveness and safety of biliary fully-covered self-expandable metal stents (BFCSEMS) and lumen-apposing metal stents with electrocautery (EC-LAMS). Patients and methods From April 2008 to March 2017, consecutive patients with symptomatic PFC drained under EUS-guidance with metal stents were included. Patients drained with EC-LAMS were considered the study group and those drained with BFCSEMS the control group. Two primary endpoints were evaluated: effectiveness (defined as reduction of ≥ 50 % of PFC size in cross-sectional imaging and improvement of symptoms 6 months after the transmural drainage) and safety. Results Thirty patients were drained with EC-LAMS and 60 patients with BFCSEMS. Patients and PFC baseline characteristics in both groups were similar. Use of a coaxial double pigtail plastic stent and a nasocystic lavage catheter was significantly less frequent in patients drained with EC-LAMS (33 % vs. 100 %, and 13 % vs. 58 %, respectively; P  < 0.0001). Technical success was 100 % in both groups. Procedure time was < 30 minutes in all patients drained with EC-LAMS and over 30 minutes in all patients drained with BFCSEMS ( P  = 0.0001). Clinical success was higher with a tendency to significance in patients drained with EC-LAMS (96 % vs. 82 %, P  = 0.055) and the adverse event rate was lower (4 % vs. 18 %, P  = 0.04). No case of procedure-related mortality was recorded. Conclusions EC-LAMS and BFCSEMS are both effective for EUS-guided drainage of PFC. However, EC-LAMS requires less time to be performed and appears to be safer.

Metastasis of dermatofibrosarcoma diagnosed by capsule endoscopy.

In the study of obscure gastrointestinal bleeding, which includes iron-deficiency anemia, the capsule endoscopy is a valuable diagnostic tool. In the different series the presence of tumors reaches 16% as the cause of it. We present the case of a rare tumor with metastatic extension in the small intestine in which the capsule endoscopy was key to the diagnosis and survival of the patient.

Diagnóstico atípico mediante cápsula endoscópica: enfermedad de Whipple / Atypical diagnosis diagnosis by endoscopic capsule: Whipple´s disease

La enfermedad de Whipple es una infección sistémica crónica producida por el actinomiceto Tropheryma whipplei. Las pruebas endoscópicas son claves en el diagnóstico ya que permiten la toma de biopsia y su estudio anatomopatológico para el diagnóstico definitivo de esta entidad. Presentamos un caso de enfermedad de Whipple en el que la cápsula endoscópica, poco común para el diagnóstico de esta afección, fue clave para el mismo y su realización antes y después del tratamiento antibiótico permite describir la evolución macroscópica de los hallazgos en intestino delgado. Este caso ilustra la utilidad de la cápsula endoscópica al permitir un estudio completo del intestino delgado en esta enfermedad en la que hasta el 30% de los pacientes puede cursar con gastroscopia normal (AU)

Whipple´s disease is a chronic systemic infection produced by the actinomycete Tropheryma whipplei. Endoscopic tests are key in the diagnosis as they allow biopsy and histopathological examination for definitive diagnosis of this entity. We present a case of Whipple´s disease where capsule endoscopy, uncommon for the diagnosis of this condition, was essential for it and its performance before and after antibiotic treatment allows to describe the macroscopic evolution of the findings in the small bowel. This case illustrates the utility of capsule endoscopy to allow complete examination of the small bowel disease in which up to 30% of patients may present with normal endoscopy (AU)
