ObjectiveAlthough gastric per-oral endoscopic myotomy (G-POEM) is considered a promising technique for the management of refractory gastroparesis, high-quality evidence is limited. We prospectively investigated the efficacy and safety of G-POEM in unselected patients with refractory gastroparesis.DesignIn five tertiary centres, patients with symptomatic gastroparesis refractory to standard medical therapy and confirmed by impaired gastric emptying were included. The primary endpoint was clinical success, defined as at least one score decrease in Gastroparesis Cardinal Symptom Index (GCSI) with ≥25% decrease in two subscales, at 12 months. GCSI Score and subscales, adverse events (AEs) and 36-Item Short Form questionnaire of quality of life were evaluated at baseline and 1, 3, 6 and 12 months after G-POEM. Gastric emptying study was performed before and 3 months after the procedure.ResultsOf 80 enrolled patients, 75 patients (94%) completed 12-month follow-up. Clinical success at 12 months was 56% (95% CI, 44.8 to 66.7). GCSI Score (including subscales) improved moderately after G-POEM (p<0.05). In a regression model, a baseline GCSI Score >2.6 (OR=3.23, p=0.04) and baseline gastric retention >20% at 4 hours (OR=3.65, p=0.03) were independent predictors of clinical success at 12 months, as was early response to G-POEM at 1 month after therapy (OR 8.75, p<0.001). Mild procedure-related AEs occurred in 5 (6%) patients.ConclusionG-POEM is a safe procedure, but showed only modest overall effectiveness in the treatment of refractory gastroparesis. Further studies are required to identify the best candidates for G-POEM; unselective use of this procedure should be discouraged.Trial registration numberClinicalTrials.gov Registry NCT02732821.
Background and Aims: Endoscopic resection of lesions involving the appendiceal orifice (AO) remains a challenge. We aim to report the outcomes of full-thickness resection device (FTRD) for the resection of appendiceal lesions and identify factors associated with the occurrence of appendicitis.
Methods: This is a retrospective study at 18 tertiary-care centers (12 U.S., Canada 1, 5 Europe) between 11/2016 and 8/2020. Consecutive patients who underwent resection of AO lesions using the FTRD were included. The primary outcome was the rate of R0 margin resection in neoplastic lesions, defined as negative lateral and deep margins on post-resection histologic evaluation. Secondary outcomes included the rates of; technical success (en bloc resection), clinical success (technical success without need for further surgical interventions), post-resection appendicitis, and polyp recurrence. Results: A total of 66 patients (mean age 64 yr., 29 F) underwent resection of colonic lesions (mean size 14.5 (6.2) mm) involving the AO, with 40 (61%) deep extending into the appendiceal lumen. Technical success was achieved in 59/66 (89%) cases, out of which, 56 were found to be neoplastic lesions on post-resection pathology. Clinical success was achieved in 53/66 (80%). R0 resection was achieved in 52/56 (93%) cases. Out of the 58 patients of whom EFTR was completed and had no prior history of appendectomy, appendicitis was reported in 10 (17%) cases, with 6 (60%) requiring surgical appendectomies. Follow-up colonoscopy was completed in 41 cases with evidence of recurrence in 5 (12.2%).
Conclusions: FTRD is a promising non-surgical alternative for resecting appendiceal lesions but
appendicitis occurs in 1 out of 6 cases.
Background: Liver injury is commonly seen in coronavirus disease 2019 (COVID-19). However, the mechanism behind liver injury, particularly in severe and critical COVID-19 patients, remains unclear and the clinical course is poorly described. Methods: We conducted a single-center, retrospective cohort study of consecutive hospitalized severe and critically ill COVID-19 patients with or without liver injury who underwent immunologic testing (IL-6, IL-8, TNF-α, and IL-1ß). Liver injury was defined as peak aminotransferases ≥3x ULN
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
