Insulated-tip knife endoscopic polypectomy for difficult pedunculated colorectal polyps: a prospective pilot study.
Observational study in International journal of colorectal disease, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEndoscopic polypectomy is widely used for colorectal polyps. However, for giant pedunculated colorectal polyps (≥3 cm), conventional techniques are so difficult with en bloc resection that patients had to be transferred to surgery. We had firstly reported our first experience with an insulated-tip knife to successfully remove a giant pedunculated polyp in the sigmoid colon. In this study, our aim was to explore safety and feasible of insulated-tip knife endoscopic polypectomy (IT-EP) for difficult pedunculated colorectal polyps.
methodsA total of seven consecutive patients with giant pedunculated colorectal polyps (≥3 cm) were prospectively enrolled. IT-EP was conducted with the help of clips for all the seven patients, and data of them was recorded and analyzed.
resultsOf seven patients, five were men and two were women with a mean age 61 years (49-72 years). The mean diameter of polyp head and stalk was 36.4 ± 4.9 mm (30-42 mm) and 14.6 ± 3.6 mm (10-20 mm), respectively. All the polyps were successfully removed with IT-EP, with a mean operation time of 14.9 ± 3.5 min (11-20 min). No serious bleeding or perforation was experienced, and no surgery was needed. There was no recurrence or residual of polyps at a mean 8.1-month follow-up.
conclusionsInsulated-tip knife endoscopic polypectomy is a safe and feasible alternative for difficult pedunculated colorectal polyps.
