Argon plasma coagulation was reported to be useful in endoscopic hemostasis. However, the long-term outcomes have been poorly evaluated. This study was designed to assess the long-term outcomes of bleeding patients with colonic angiodysplasia treated by argon plasma coagulation. METHODS: A cohort of 100 patients with gastrointestinal bleeding caused by colonic angiodysplasia was studied prospectively. The endoscopic intervention was considered successful if there was no further overt bleeding and hemoglobin concentration was stabilized (primary end point). Secondary end points were the requirement of blood transfusions, the need for surgery, bleeding-related mortality, and overall mortality. RESULTS: Overt bleeding resolved and hemoglobin levels were stabilized without transfusions or iron therapy in 85 of 100 patients (85 percent) after a median follow-up of 20 (range, 6-62) months. Transfusion requirements ceased in 90 percent of patients and only one required surgery. No patient died because of hemorrhage. In the subgroup of patients with anemia, mean hemoglobin levels increased from 9.3 (range, 5.5-12.2) g/dl before treatment to 12.6 (range, 7.4-16.7) g/dl after treatment (P < 0.01). The probability of remaining free of rebleeding at one and two year follow-up was 98 percent (95 percent confidence interval, 96-100) and 90 percent (95 percent confidence interval, 83-97), respectively. Among 118 procedures, only two complications were observed (1.7 percent). CONCLUSIONS: Endoscopic argon plasma ablation therapy is useful in the management of bleeding from colonic angiodysplasia.","is_dataset_classified":null,"base_score":4.564348191467836,"endowment":4.564348191467836,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"17024322","pmcid":null,"openalex_id":"https://openalex.org/W2040741382","authors":[],"funders":[],"total_grants":0,"fwci":1.8646,"citation_percentile":0.85318133,"influential_citations":0,"citation_trend":[{"year":2012,"count":3},{"year":2013,"count":7},{"year":2014,"count":4},{"year":2015,"count":9},{"year":2016,"count":7},{"year":2017,"count":3},{"year":2018,"count":6},{"year":2019,"count":12},{"year":2020,"count":4},{"year":2021,"count":5},{"year":2022,"count":7},{"year":2023,"count":3},{"year":2024,"count":2},{"year":2025,"count":1},{"year":2026,"count":2}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://www.ovid.com/00003453-200649100-00004","host_type":"publisher"},{"url":"https://doi.org/10.1007/s10350-006-0684-1","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/17024322","host_type":"repository"}],"fields_of_study":["Gastrointestinal Bleeding Diagnosis and Treatment","Abdominal vascular conditions and treatments","Abdominal Trauma and Injuries","Adult","Aged","Aged, 80 and over","Angiodysplasia","Argon","Colonic Diseases","Female","Gastrointestinal Hemorrhage","Hemostasis, Endoscopic","Humans","Laser Coagulation","Male","Middle Aged","Observation","Prospective Studies","Treatment Failure","Treatment Outcome"],"mesh_terms":["Adult","Aged","Aged, 80 and over","Argon","Colonic Diseases","Female","Gastrointestinal Hemorrhage","Humans","Male","Middle Aged","Prospective Studies","Hemostasis, Endoscopic","Angiodysplasia","Treatment Outcome","Laser Coagulation","Treatment Failure","Observation"],"keywords":["Argon plasma coagulation","Medicine","Angiodysplasia","Surgery","Confidence interval","Gastrointestinal bleeding","Colonoscopy","Blood transfusion","Hemoglobin","Packed red blood cells","Gastroenterology","Anemia","Internal medicine","Endoscopy","Colorectal cancer","Cancer"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T17:12:35.715126Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
