    IT IS REPORTED IN THE LITERATURE ARTICLE TITLED:¿ LONG-TERM OUTCOMES OF ENDOSCOPIC BALLOON DILATION FOR INTESTINAL STRICTURES IN PATIENTS WITH CROHN¿S DISEASE DURING MAINTENANCE TREATMENT WITH ANTI-TUMOR NECROSIS FACTOR ALPHA ANTIBODIES,¿ PATIENT EXPERIENCED ADVERSE EVENTS DURING AND AFTER PROCEDURES USING OLYMPUS DEVICES. CASE WITH PATIENT IDENTIFIER (B)(6) REPORTS PCF-P240AI. CASE WITH PATIENT IDENTIFIER (B)(6) REPORTS PCF-Q260AI. STUDY BACKGROUND AND AIM: EFFICACY OF ENDOSCOPIC BALLOON DILATION (EBD) FOR INTESTINAL STRICTURES IN PATIENTS WITH CROHN¿S DISEASE (CD) RECEIVING ANTI-TUMOR NECROSIS FACTOR ALPHA ANTI BODIES (ANTI-TNF) AS MAINTENANCE THERAPY IS UNCLEAR. WE INVESTIGATED THE LONG-TERM EFFICACY AND SAFETY OF EBD FOR INTESTINAL STRICTURES IN PATIENTS WITH CD RECEIVING ANTI-TNF. METHODS: RETROSPECTIVE DATA ANALYSIS FROM PATIENTS WITH CD WHO RECEIVED ANTI-TNF AS MAINTENANCE THERAPY FROM 2008 TO 2017, UNDERWENT EBD, AND WERE FOLLOWED UP FOR =6 MONTHS. THE PRIMARY ENDPOINT WAS THE CUMULATIVE SURGERY-FREE RATE. THE MAIN SECONDARY ENDPOINTS WERE TECHNICAL SUCCESS, REPEAT EBD RATE, RISK FACTORS AFFECTING SURGICAL OUTCOMES, AND SAFETY. RESULTS: SEVENTY-TWO PATIENTS WITH CD WERE ASSESSED. THE MEDIAN OBSERVATION PERIOD AFTER EBD WAS 50 MONTHS. THE TECHNICAL SUCCESS RATE WAS 67%. THE 3- AND 5-YEAR CUMULATIVE SURGERY-FREE RATES WERE 81.1% AND 73.5%, RESPECTIVELY. THE REPEAT EBD RATE WAS 74%. MULTIVARIABLE ANALYSES SHOWED THAT RISK FACTORS AFFECTING SURGICAL OUTCOMES WERE AGE AT DISEASE ONSET =16 YEARS (HAZARD RATIO 3.69; 95% CONFIDENCE INTERVAL 1.36¿10.01; P = 0.011). SERIOUS COMPLICATIONS REQUIRING SURGERY DEVELOPED IN THREE PATIENTS. CONCLUSIONS: ENDOSCOPIC BALLOON DILATION WAS AN EFFECTIVE AND SAFE SHORT-TERM TREATMENT AND A USEFUL LONG-TERM TREATMENT FOR CD PATIENTS WITH INTESTINAL STRICTURES RECEIVING ANTI-TNF AS MAINTENANCE THERAPY. THE ONLY SERIOUS COMPLICATION OBSERVED WAS PERFORATION IN THREE PATIENTS; HOWEVER, THEY UNDERWENT SURGERY AND RECOVERED. PERFORATION WAS OBSERVED IN 3/72 (4.2%) PATIENTS AND IN 3/290 (1.0%) ENDOSCOPIC PROCEDURES. PERFORATION DURING EBD OCCURRED ONLY IN ONE PATIENT. PERFORATION DURING INSERTION OCCURRED IN TWO PATIENTS, BOTH OF WHICH WERE IN THE AFFECTED REGION OF THE ILEUM WITH A LONGITUDINAL ULCER. BLEEDING REQUIRING TRANSFUSION OR SERIOUS COMPLICATIONS REQUIRING LONG-TERM HOSPITALIZATION WERE NOT NOTED. THERE IS NO REPORT OF ANY OLYMPUS DEVICE MALFUNCTION REPORTED IN ANY PROCEDURE DESCRIBED IN THIS LITERATURE.
