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

backgroundWhether laparoscopic surgery after prior abdominal surgery (PAS) is safe and feasible for colorectal cancer (CRC) remains controversial. The present study aimed to evaluate the impact of PAS on short-term outcomes following laparoscopic CRC surgery.

methodsWe performed retrospective analysis used propensity score-matched analysis to reduce the possibility of selection bias. Participants comprised 1284 consecutive patients who underwent elective laparoscopic CRC surgery between 2010 and 2020. Patients were divided into two groups according to PAS. Patients with PAS were then matched to patients without these conditions. Short-term outcomes were evaluated between groups in the overall cohort and matched cohort, and risk factors for conversion to laparotomy and severe postoperative complications were analyzed.

resultsAfter propensity score matching, we enrolled 762 patients (n = 381 in each group). Before matching, significant group-dependent differences were observed in sex, age, primary tumor site, pathological (p) T stage, and type of procedure. No significant difference was found between groups in terms of rate of conversion to laparotomy, estimated blood loss, rate of extended resection, length of postoperative stay, and postoperative complications. After matching, estimated operative time was significantly longer in the PAS group (p = 0.01). Significant differences were found between groups in terms of reason for conversion to laparotomy. Multivariate analyses identified significant risk factors for conversion to laparotomy as pT stage ≥ 3 (odds ratio [OR] 2.36; 95% confidence interval [CI] 1.05-5.26) and body mass index ≥ 25 kg/m

conclusionsLaparoscopic CRC surgery after PAS showed acceptable short-term outcomes compared to Non-PAS. The laparoscopic approach appears safe and feasible for CRC regardless of whether the patient has a history of PAS.
