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

backgroundHigh intraabdominal pressure (IAP) during laparoscopic surgery has been associated with postoperative discomfort. Effects on nausea and access have not been subjected to randomized studies. In cholecystectomy, lower IAP may cause less pain, but nausea and surgical access in RYGB surgery have not been investigated. We studied the influence of two IAP levels on surgical access, operation time, postoperative pain, and nausea.

methodsFifty consecutive female gastric bypass patients were randomized to intraabdominal pressure of 12 (IAP12) or 18 (IAP18) mm Hg. Surgeons and personnel were blinded to randomization; study groups were well matched for age and BMI. Operative time was noted in minutes. Visual analogue scales were used for assessing access and for patients assessing pain (abdomen-shoulder) and nausea (supine-standing) at six time points during the first 16 postoperative hours. Rescue medication was recorded.

resultsIn 3/25 patients in the IAP12 group, the code was broken due to access problems vs. 0/25 in the IAP18 group (p = 0.1398). Operative time did not differ. Access was significantly better for IAP18 (92.2 ± 2.3 vs. 69.3 ± 4.2; p = 0.0001). Postoperative shoulder pain was maximal after 6 h but throughout less than in the abdomen (p < 0.0001); there were no differences in pain between IAP18 and IAP12 (p = 0.7408). Postoperative nausea was significantly greater standing than supine but without differences between groups.

conclusionHigher IAP gives better surgical access in laparoscopic Roux-en-Y gastric bypass with no negative effect on pain or nausea.
