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

backgroundWithin the last years, single-incision laparoscopic cholecystectomy (SLC) emerged as an alternative to multiport laparoscopic cholecystectomy (MLC). SLC has advantages in cosmetic results, and postoperative pain seems lower. Overall complications are comparable between SLC and MLC. However, long-term results of randomized trials are lacking, notably to answer questions about incisional hernia rates, long-term cosmetic impact and chronic pain.

methodsA randomized trial of SLC versus MLC with a total of 193 patients between December 2009 and June 2011 was performed. The primary endpoint was postoperative pain on the first day after surgery. Secondary endpoints were conversion rate, operative time, intraoperative and postoperative morbidity, technical feasibility and hospital stay. A long-term follow-up after surgery was added.

resultsNinety-eight patients (50.8%) underwent SLC, and 95 patients (49.2%) had MLC. Pain on the first postoperative day showed no difference between the operative procedures (SLC vs. MLC, 3.4 ± 1.8 vs. 3.7 ± 1.9, respectively; p = 0.317). No significant differences were observed in operating time or the overall rate of postoperative complications (4.1% vs. 3.2%; p = 0.731). SLC exhibited better cosmetic results in the short term. In the long term, after a mean of 70.4 months, there were no differences in incisional hernia rate, cosmetic results or pain at the incision between the two groups.

conclusionsTaking into account a follow-up rate of 68%, the early postoperative advantages of SLC in relation to cosmetic appearance and pain did not persist in the long term. In the present trial, there was no difference in incisional hernia rates between SLC and MLC, but the sample size is too small for a final conclusion regarding hernia rates.
