AS PER PAPER - "AFTER STENT INSERTION, TWO PATIENTS SUFFERED FROM TENESMUS. FENG ET AL 2020 ¿ ENDOSCOPIC SELF-EXPANDABLE METALLIC STENT INSERTION WITHOUT FLUOROSCOPIC GUIDANCE IS FEASIBLE AND SAFE FOR ACUTE COLONIC OBSTRUCTION CAUSED BY COLORECTAL CANCER THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE THE EFFICACY AND FEASIBILITY OF THIS TECHNIQUE USING SEMS INSERTION. FROM JANUARY 2016 TO DECEMBER 2018, 36 PATIENTS WITH CRC OBSTRUCTION UNDERWENT ENDOSCOPIC SEMS INSERTION IN OUR CENTER. THE WHOLE STENTING PROCEDURE WAS MONITORED UNDER ENDOSCOPIC GUIDANCE ONLY. A THROUGH-THE-SCOPE TECHNIQUE WAS USED FOR ALL STENT INSERTIONS. A NITI-S UNCOVERED COLORECTAL STENT WITH A DIAMETER OF 22¿25MM AND A LENGTH OF 100MM FROM MICROTECH (NANJING, CHINA) OR COOK MEDICAL EVOLUTION(BLOOMINGTON,IN,USA) WAS USED ACCORDING TO THE ENDOSCOPIST¿S PREFERENCE. BRIEFLY, WHEN THE COLONOSCOPE REACHED THE OBSTRUCTION, A SPHINCTEROTOME (MICROTECH, NANJING, CHINA) FOR ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY (ERCP) WITH A 0.035-INCH GUIDEWIRE (MICRO-TECH, NANJING, CHINA) OR JAGWIRE (BOSTON SCIENTIFIC, NATICK, MA, USA) WAS INTRODUCED. THE GUIDEWIRE WAS INSERTED TO TRAVERSE THE STRICTURE. THE GUIDEWIRE WAS INSERTED FOR APPROXIMATELY 40 CM, THEN PULLED BACKWARD AT APPROXIMATELY 10 CM, FOLLOWED BY AN ADDITIONAL INSERTION FOR APPROXIMATELY 20 CM. SUCCESSFUL GUIDEWIRE INSERTION WAS JUDGED BY A SMOOTH PASSAGE OF THE GUIDEWIRE WITHOUT ANY RESISTANCE. THE SPHINCTEROTOME WAS THEN INSERTED ALONG THE GUIDEWIRE TO CONFIRM THE PASSAGE OF THE OBSTRUCTION. THE DELIVERY SYSTEM WAS ADVANCED OVER THE GUIDEWIRE AND WAS GUIDED INTO THE SITE OF OBSTRUCTION UNTIL THE DISTAL END OF THE STENT WAS APPROXIMATELY 2CM AT THE EDGE OF THE TUMOR. IN THE STENT DEPLOYMENT PROCEDURE, THE DISTAL END OF THE STENT WAS KEPT 2CM BEYOND THE DISTAL EDGE OF THE LESION, WHILE THE OUTER SHEATH WAS RETRACTED. THE WHOLE PROCEDURE WAS MONITORED BY THE COLONOSCOPIC GUIDANCE ONLY. AFTER STENT INSERTION, TWO PATIENTS SUFFERED FROM TENESMUS. THE PATIENTS OBTAINED SYMPTOM RELIEF AFTER CONSERVATIVE THERAPY. THE EXACT RPN UNKNOWN, 3 POSSIBLE RPNS: EVO-25-30-6-C, EVO-25-30-8-C ,EVO-25-30-10-C. IT CANNOT BE CONFIRMED OF THE OVERALL 36 STENTS PLACED, WHICH WERE COOK STENTS, THIS FILE IS CREATED TO CAPTURE THE POTENTIAL THAT IT COULD HAVE BEEN A COOK EVOLUTION STENT. THIS FILE WAS CREATED TO CAPTURE TWO CASES OF TENESMUS.
