A 78-year-old man with a 12-h history of near syncope and painless hematochezia was admitted to our hospital. Following the transfusion of 4 U of blood and continued hematochezia, a colonoscopy was performed. Active bleeding was seen as continuous arterial spurting from a single diverticulum located in the middle ascending colon. This diverticulum was seamed by four endoclips. The next day, the patient became febrile with a temperature of 39.2℃. Laboratory data included a white blood cell count of 18 100/mm3 and a C-reactive protein level of 3.4 mg/dL. He was diagnosed with sepsis since Escherichia coli was detected in the blood culture. Antibiotics were started. Four days later his fever had improved and laboratory data improved 9 d later.展开更多

The critical element in the quality of colonoscopy in terms of polyp detection and removal continues to be the performance of the endoscopist, independent of patient-related factors. Improved results in terms of polyp detection and complete removal have implications regarding the development of screening and surveillance intervals and the reduction of interval cancers after negative colonoscopy. Advances in colonoscopy techniques such as high-definition colonoscopy, hood-assisted colonoscopy and dye-based chromoendoscopy have improved the detection of small and flat-type colorectal polyps. Virtual chromoendoscopy has not proven to improve polyp detection but may be useful to predict polyp pathology. The majority of polyps can be removed endoscopically. Available polypectomy techniques include cold forceps polypectomy, cold snare polypectomy, conventional polypectomy, endoscopic mucosal resection and endoscopic submucosal dissection. The preferred choice depends on the polyp size and characteristics. Other useful techniques include colonoscopic hemostasis for acute colonic diverticular bleeding, endoscopic decompression using colonoscopic stenting, and transanal tube placement for colorectal obstruction. Here we review the current knowledge concerning the improvement of quality measures in colonoscopy and colonoscopy-related therapeutic interventions.展开更多
