1 · What the graph read from it

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.

2 · The registry

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

backgroundThe majority of endoscopically unresectable colon polyps (EUCP) are treated by segmental colectomy. However, up to 90% of EUCP do not harbor malignancy, making colectomy an unnecessary procedure. To minimize unnecessary segmental colectomy, we established a progressive treatment algorithm utilizing colon conservation techniques (CCT). In our progressive CCT algorithm, patients with EUCP first underwent endoscopic submucosal dissection (ESD). If unsuccessful, they progressed to combined endo-laparoscopic surgery (CELS) and ultimately to segmental colectomy, if necessary.

methodsWe performed a retrospective analysis of all patients treated by our progressive CCT algorithm from August 2015 to April 2019. Demographic information, polyp characteristics, and clinical outcomes were analyzed. We also compared the outcomes of our CCT algorithm group to 156 patients undergoing segmental colectomy for EUCP at related institutions from August 2015 to August 2018.

resultsA total of 102 EUCP in 97 patients were treated with our progressive CCT algorithm. Of these, 76 of 102 (75.5%) EUCP were removed without requiring segmental colectomy, with 42 EUCP removed via ESD and 34 via CELS. Interval surveillance colonoscopy confirmed that 72 of 97 (74.2%) patients with EUCP treated by CCT completely avoided segmental colectomy. Polyps > 5 cm in size was a significant predictor of CCT failure (OR 3.83, P = 0.03). When compared to an external cohort of patients undergoing segmental colectomy for EUCP, the CCT algorithm was associated with longer operative time, but shorter length of stay, with no difference in postoperative complications. The estimated total healthcare cost of the CCT algorithm was lower than segmental colectomy ($10,956.77 versus $16,692.94), with more dramatic cost savings seen in ESD ($4,492.70) and CELS ($8,507.06).

conclusionsAn established progressive CCT algorithm can result in high colon conservation rate and decrease associated health care costs compared to segmental colectomy. It is a reasonable treatment strategy for patients with EUCP.
