2 FDA recall records name at least one of these models by its device identifier, 2 still open.

Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

  OLYMPUS MEDICAL SYSTEMS CORP. (OMSC) REVIEWED A LITERATURE TITLED, "UTILITY OF PROPHYLACTIC CLIPPING AFTER COLORECTAL COLD SNARE POLYPECTOMY IN PATIENTS ON ORAL ANTITHROMBOTIC AGENTS." LITERATURE SUMMARY BACKGROUND AND AIMS: THERE IS NO CONSENSUS ON THE EFFECTIVENESS OF PROPHYLACTIC CLIPPING AFTER COLONIC COLD SNARE POLYPECTOMY (CSP). THIS STUDY AIMED TO EVALUATE THE UTILITY OF PROPHYLACTIC CLIPPING IN PREVENTING DELAYED BLEEDING (DB) AFTER COLORECTAL CSP IN PATIENTS ON ANTITHROMBOTIC AGENTS. METHODS: WE RETROSPECTIVELY RECRUITED CONSECUTIVE PATIENTS ON ANTITHROMBOTIC AGENTS WHO UNDERWENT COLORECTAL CSP IN (B)(6) HOSPITAL. THE DB RATE WAS COMPARED BETWEEN PATIENTS WITH AND WITHOUT PROPHYLACTIC CLIPPING. RESULTS: THE STUDY INCLUDED 133 PATIENTS (422 POLYPS) REQUIRING PROPHYLACTIC CLIPPING AND 85 PATIENTS (282 POLYPS) NOT REQUIRING PROPHYLACTIC CLIPPING. THERE WERE NO SIGNIFICANT DIFFERENCES IN DB AND HEMATOCHEZIA RATES BETWEEN THE GROUPS. BY WEIGHTED LOGISTIC REGRESSION ANALYSIS, THE ODDS RATIO OF HEMATOCHEZIA WAS 0.557 (95% CONFIDENCE INTERVAL, 0.225-1.378; P = .205) IN PATIENTS WITHOUT CLIPPING COMPARED TO THOSE WITH CLIPPING. THE RATES OF HEMATOCHEZIA AND DB WERE 4% (5 OF 133) AN

  IT WAS REPORTED THAT A PATIENT DEVELOPED BLOODY STOOLS AFTER A LOW-POWER PURE-CUT HOT SNARE POLYPECTOMY (LPPC HSP). THE DEVICE WAS USED WITH NO INTRAOPERATIVE BLEEDING AND NO CLIP CLOSURE. THE PATIENT HAD ANGINA PECTORIS AND WAS TAKING ASPIRIN ORALLY, WHICH WAS DISCONTINUED 3 DAYS BEFORE TREATMENT AND SCHEDULED TO BE RESUMED THE NEXT DAY. BLOODY STOOL WAS OBSERVED FROM THE EVENING OF THE TREATMENT DAY, AND ALTHOUGH THE PATIENT WAS INSTRUCTED TO POSTPONE THE RESUMPTION OF ASPIRIN, THE BLOODY STOOL CONTINUED UNTIL POST-OP DAY 3 (POD3). ON POD3, AFTER PRETREATMENT, A COLONOSCOPY WAS PERFORMED, AND EXPOSED BLOOD VESSELS EQUIVALENT TO FORREST CLASSIFICATION IIA WERE FOUND AT THE ULCER BASE AFTER LPPC HSP. IT WAS DETERMINED THAT THE POST-BLEEDING WAS DUE TO LPPC HSP, AND CLIP CLOSURE WAS PERFORMED.

  OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "GEL IMMERSION ENDOSCOPIC MUCOSAL RESECTION FOR EARLY GASTRIC NEOPLASMS: A MULTICENTER CASE SERIES STUDY". LITERATURE SUMMARY: SEVERAL CASES HAVE BEEN REPORTED THAT SUGGEST THE EFFICACY OF GEL IMMERSION ENDOSCOPIC MUCOSAL RESECTION (GI-EMR) FOR GASTRIC NEOPLASMS. HOWEVER, NO STUDY HAS EVALUATED TREATMENT OUTCOMES OF GI-EMR FOR GASTRIC NEOPLASMS. THIS STUDY AIMED TO INVESTIGATE THE EFFICACY AND SAFETY OF GI-EMR FOR EARLY GASTRIC NEOPLASMS. NINE PATIENTS (17 LESIONS) UNDERGOING GASTRIC GI-EMR WERE INCLUDED, WITH A MEDIAN LESION SIZE OF 10MM (INTERQUARTILE RANGE [IQR] 5¿13 MM). ALL LESIONS WERE PROTRUDING OR FLAT ELEVATED. THE MEDIAN PROCEDURE TIME WAS 3 MINUTES (IQR 2¿5) AND EN BLOC RESECTION WAS ACHIEVED IN ALL CASES. AMONG 15 NEOPLASTIC LESIONS, THE R0 RESECTION RATE WAS 86.7% (13/15 LESIONS). ADVERSE EVENTS INCLUDED IMMEDIATE BLEEDING REQUIRING HEMOSTASIS IN TWO CASES, WHICH WAS CONTROLLED ENDOSCOPICALLY. NO DELAYED BLEEDING OR PERFORATION OCCURRED. IN CONCLUSION, GI-EMR MAY BE A SAFE AND EFFECTIVE TREATMENT FOR EARLY, SMALL GASTRIC NEOPLASMS. HOWEVER, DUE TO THE SMALL SAMPLE IN THE PRESENT STUDY, FURTHER INVESTIGATION IS REQUIRED R

  IT WAS REPORTED THAT WHEN PERFORMING A COLD POLYPECTOMY ON A POLYP WITH A LESION SIZE OF 5 MM ("COLD CUT" -THERAPEUTIC PROCEDURE) IN THE LARGE INTESTINE, THE POLYP COULD NOT BE DETACHED/TORN WHEN IT WAS STRANGLED WITH A SINGLE USE ELECTROSURGICAL SNARE. DUE TO THE INABILITY TO PERFORM POLYPECTOMY, THE PROCEDURE WAS CHANGED TO "EMR PROCEDURE" AND THE POLYP WAS MECHANICALLY EXCISED WHICH COULD THEN BE REMOVED FROM THE TISSUE ("THE TREATMENT WAS PERFORMED BY LOCALLY INJECTING IT INTO THE TREATMENT AREA WITHOUT USING HIGH FREQUENCY") THE PROCEDURE WAS EXTENDED; HOWEVER, THE DELAY IS UNKNOWN. THE PROCEDURE WAS COMPLETED BY REPLACING THE DEVICE. NO ADDITIONAL MEDICATION WAS GIVEN TO THE PATIENT NO REPORTS OF HEALTH HAZARDS TO THE PATIENT. FUTHER PROCEDURAL DETAILS AND OUTCOME OF PATIENT WERE REQUESTED BUT NOT AVAILABLE AT THE TIME OF THE REPORT.

  OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "EFFICACY AND SAFETY OF COLD SNARE POLYPECTOMY OF COLORECTAL POLYPS 10-15 MM WITH A HYBRID SNARE: A PROSPECTIVE OBSERVATIONAL PILOT STUDY". THIS PROSPECTIVE SINGLE-CENTER FEASIBILITY TRIAL EVALUATED THE EFFICACY AND SAFETY OF CSP WITH A HYBRID SNARE IN POLYPS (ADENOMAS AND SSL) WITH A SIZE OF 10¿15 MM. A TOTAL OF 39 PATIENTS WITH 61 ADENOMATOUS POLYPS OR SSL WERE INCLUDED. CSP WAS FEASIBLE IN 78.7% (48/61) OF POLYPS AND THE CRR IN THIS GROUP WAS 85.4% (41/48). WHEN CSP FAILED (13/61; 21.3%), LESIONS WERE SUCCESSFULLY RESECTED USING IMMEDIATE HSP WITH THE SAME SNARE WITH A CRR OF 61.5% (8/13) IN THIS GROUP. EN BLOC RESECTION RATE BY CSP WAS 81.3% (39/48) AND 69.2% (9/13) FOR HSP, RESPECTIVELY. THE OVERALL EN BLOC RESECTION RATE WAS 78.7% (48/61).

  OLYMPUS MEDICAL SYSTEMS CORP. (OMSC) RECEIVED A LITERATURE TITLED "CAN UNDERWATER ENDOSCOPIC MUCOSAL RESECTION BE AN ALTERNATIVE TO CONVENTIONAL ENDOSCOPIC MUCOSAL RESECTION FOR SUPERFICIAL NON-AMPULLARY DUODENAL EPITHELIAL TUMORS?" LITERATURE SUMMARY OBJECTIVES: UNDERWATER ENDOSCOPIC MUCOSAL RESECTION (UEMR) IS A SIMPLER PROCEDURE FOR SUPERFICIAL NON-AMPULLARY DUODENAL EPITHELIAL TUMORS (SNADET) THAN CONVENTIONAL ENDOSCOPIC MUCOSAL RESECTION (CEMR). THIS STUDY AIMED TO EVALUATE WHETHER CEMR CAN BE SUBSTITUTED BY UEMR FOR SNADET IN TERMS OF EFFECTIVENESS, SAFETY, AND LEARNING CURVE. METHODS: A TOTAL OF 157 CONSECUTIVE PATIENTS WITH 203 SNADETS <20 MM IN DIAMETER, INCLUDING 107 LESIONS RESECTED BY CEMR AND 96 LESIONS RESECTED BY UEMR, BETWEEN JANUARY 2019 AND MAY 2023, WERE RETROSPECTIVELY RECRUITED. THE TREATMENT OUTCOMES WERE COMPARED BETWEEN THE CEMR AND UEMR GROUPS. THE RISK FACTORS FOR INCOMPLETE RESECTION BY UEMR WERE ANALYZED USING UNIVARIATE AND MULTIVARIATE ANALYSES. LESIONS IN THE UEMR GROUP WERE DIVIDED CHRONOLOGICALLY INTO FIVE PERIODS; THEREAFTER, THE EN BLOC RESECTION RATE AND PROCEDURE TIME WERE COMPARED. RESULTS: NO SIGNIFICANT DIFFERENCES EXISTED BETWEEN THE CEMR AN

BACKGROUND AND AIMS: COLD SNARE RESECTION OF COLORECTAL LESIONS HAS BEEN FOUND TO BE SAFE AND EFFECTIVE FOR AN EXPANDING SET OF COLORECTAL LESIONS. IN THIS STUDY, WE SOUGHT TO UNDERSTAND THE EFFICACY OF SIMPLE COLD SNARE RESECTION AND COLD EMR VERSUS HOT SNARE RESECTION AND HOT EMR FOR COLORECTAL LESIONS 6 TO 15 MM IN SIZE. METHODS: AT 3 U.S. CENTERS, 235 PATIENTS WITH 286 COLORECTAL LESIONS 6 TO 15 MM IN SIZE WERE RANDOMIZED TO COLD SNARING, COLD EMR, HOT SNARING, OR HOT EMR FOR NONPEDUNCULATED COLORECTAL LESIONS 6 TO 15 MM IN SIZE.
