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

backgroundWe conducted a randomized study of a laparoscopic technique for removing left-sided colon tumors that can reduce postoperative pain and other wound-related complications compared to the conventional technique. It is a novel technique of hybrid natural orifice translumenal endoscopic surgery (NOTES) colectomy (HNC) whereby laparoscopic colonic mobilization, transection, and anastomosis are performed intracorporeally. The specimen is then delivered through the anus using the transanal endoscopic operation (TEO) device, precluding the need for mini-laparotomy. We compared the short-term outcomes of patients who underwent HNC with those who underwent conventional laparoscopic colectomy (CL).

methodsPatients suffering left-sided colonic tumor were recruited and were randomized into two groups: HNC and CL. Operative data and complications were prospectively recorded and analyzed.

resultsDuring a 3-year period, we recruited 70 patients (35 per group). No significant difference was observed between the two groups with respect to operating time (105 vs. 100 min, p = 0.851), blood loss (30 vs. 30 ml, p = 0.954), or length of hospital stay (5 vs. 5 days, p = 0.990). The maximum pain score during the first week was significantly lower in the HNC group (1 vs. 2, p = 0.017). No patients in the HNC group developed wound infection, whereas four patients in the CL group did so (p = 0.005).

conclusionsWith this hybrid NOTES technique, selected patients with left-sided colonic tumors can enjoy the full benefits of minimally invasive surgery with significantly less wound pain and a lower wound infection rate than are observed with CL.
