RESUMO

A 15-year-old adolescent boy presented with chronic constipation, difficulty in defecation, and episodic bloody stools. A rectal mass lesion was digitally palpated. Colonoscopy showed a large circumferential polypoid lesion of the mid-rectum. Snare polypectomy was performed, and histopathology confirmed a diagnosis of benign inflammatory cap polyposis. At 3-month follow-up, sigmoidoscopy showed multiple recurrences of polyps at the site of the previous rectal polypectomy, which were removed by combined hot snare polypectomy and argon plasma coagulation. At 1-year follow-up, the patient was symptom-free and had no more episodes of bloody stool. Follow-up sigmoidoscopy showed a post-polypectomy rectal mucosal scar without recurrent polypoid lesions.

RESUMO

BACKGROUND: The attachment of a transparent hood to the colonoscope tip has been reported to offer some benefits, such as enabling the endoscopist to perform the colonoscopy more easily and to save time. However, there have been no randomized, controlled trials concerning these benefits, nor have any reports been published regarding the use of hoods for the purpose of training colonoscopists. Therefore, we conducted this study to evaluate the possible benefits of the transparent soft short hood when used by both experienced and trainee endoscopist groups. METHODS: This randomized, controlled trial to assess the results of using a transparent soft short hood attached to the tip of the colonoscope was undertaken by two groups of investigators: experienced endoscopists and gastroenterologist trainees. The cecal and ileal intubation times, as well as the doses of sedative medication required, were analyzed. RESULTS: A total of 112 patients, 65 of whom were female, underwent colonoscopy by 2 endoscopists and 5 gastroenterologist trainees. Colonoscopy was complete in 100% of the patients. The study showed significant shortening of the cecal intubation time when using the soft short hood, in both the endoscopist and gastroenterologist trainee groups (6.8/4.61 min, P = 0.006; and 9.36/7.36 min, P = 0.03). The ileal intubation time had a trend to be significantly less when using the transparent hood in the trainee group (126.4/52.9 s), although this was not statistically significant (P = 0.08). The average dose of propofol, when using the transparent hood, was significantly lower in the endoscopist group (180/120 mg, P = 0.001). No significant complications occurred in the hood or non-hood groups. CONCLUSIONS: The transparent soft short hood shortened the cecal intubation time in both the experienced endoscopist and gastroenterologist trainee groups, as well as reducing the dose of sedative medication required in the experienced endoscopist group. Interestingly, it also reduced the trainee ileal intubation time. The attachment of this type of hood enabled both the experienced endoscopists and gastroenterological trainees to perform colonoscopy more quickly and easily, without any complications.
