    IT IS REPORTED IN THE LITERATURE TITLED "STUDY OF 109 CASES BY ENDOSCOPIC TREATMENT (ANTI-REFLUX MUCOSECTOMY: ARMS) FOR ACID SECRETION INHIBITOR (PPI) RESISTANT REFRACTORY GASTROESOPHAGEAL REFLUX DISEASE (GERD) (WITH VIDEO) ", THREE PATIENTS EXPERIENCED ADVERSE EFFECTS DURING OR AFTER AN ENDO-REFLUX MUCOSECTOMY (ARMS) USING A DISPOSABLE ELECTROSURGICAL SNARE. STUDY AIM: INVESTIGATE THE EFFICACY OF ARMS IN PATIENTS WITH PPI REFRACTORY GERD. METHOD: RETROSPECTIVE REVIEW OF 109 PATIENTS WITH PPI REFRACTORY GERD WHO UNDERWENT ARMS AND COMPARED THE QUESTIONNAIRE SCORES, ACID-EXPOSURE TIMES, NUMBER OF DEMEESTER SCORE, PROXIMAL REFLUX, AND PPI DISCONTINUATION RATES BEFORE AND AFTER ARMS. RESULTS: SUBJECTIVE SYMPTOMS WERE SIGNIFICANTLY IMPROVED (P<0.01) AND PPI COULD BE DISCONTINUED IN 40-50% OF THE PATIENTS AFTER ARMS. IN ADDITION, IMPROVEMENT IN SUBJECTIVE SYMPTOMS WAS MAINTAINED IN THE 3-YEAR FOLLOW-UP PATIENTS. ACID-EXPOSURE TIME OR DEMEESTER SCORE IMPROVED AFTER ARMS (P<0.01), BUT PROXIMAL REFLUX DID NOT IMPROVE SIGNIFICANTLY (P=0.0846). CONCLUSION: ARMS IS A VALUABLE MINIMALLY INVASIVE TREATMENT FOR PEOPLE WITH PPI REFRACTORY GERD. THE EFFECTIVENESS OF TREATMENT IS DUE TO INHIBITION OF ACID REFLUX BY SCAR FORMATION IN THE CARDIA. TWO POSTOPERATIVE BLEEDING EVENTS OCCURRED IN PATIENTS. THESE PATIENTS WERE TREATED WITH ENDOSCOPIC HEMOSTASIS WITHOUT THE USE OF BLOOD TRANSFUSIONS. MINOR PERFORATION WAS OBSERVED IN ONE PATIENT. THIS PATIENT WAS TREATED WITH ENDOSCOPIC CLIP CLOSURE OF THE DEFECT. NO ADDITIONAL CONSEQUENCES TO THE PATIENTS WERE REPORTED. THERE IS NO REPORT OF ANY OLYMPUS DEVICE MALFUNCTION IN ANY PROCEDURE DESCRIBED IN THIS STUDY.
