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.

Abstract

purposeThe aim of this study was to compare the long-term outcomes of total laparoscopic surgery with Natural Orifice Specimen Extraction (NOSE) with those for conventional laparoscopy (CL)-assisted surgery for treating rectal cancers.

methodsWe reviewed the prospectively collected records of 844 patients (163 NOSE and 681 CL) who underwent curative surgery for mid- or upper rectal cancers from January 2006 to November 2012. We applied propensity score analyses and compared oncological outcomes for the NOSE and CL groups in a 1:1 matched cohort.

resultsAfter propensity score matching, each group included 138 patients; the NOSE and CL groups did not differ significantly in terms of baseline clinical characteristics. The median follow-up was 57.7 months (interquartile range, 42.4-82.5 months). The combined 5-year local recurrence rate for all tumor stages was 4.1% (95% confidence interval [CI], 0.9%-7.4%) in the NOSE group and 3.0% (95% CI, 0%-6.3%) in the CL group (P = 0.355). The combined 5-year disease-free survival rates for all stages were 89.3% (95% CI, 84.3%-94.3%) in the NOSE group and 87.3% (95% CI, 81.8%-92.9%) in the CL group (P = 0.639). The postoperative mean fecal incontinence scores at 6, 12, and 24 months were similar between the 2 groups.

conclusionIn our experience, NOSE for mid- and upper rectal cancer had acceptable long-term oncologic outcomes comparable to those of conventional minimal invasive surgery and seems to be a safe alternative to reduce access trauma.
