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

backgroundDespite the established efficacy and safety of laparoscopic sleeve gastrectomy (LSG), controversy still exists on optimal operative technique, the resection distance from pylorus (DP) being among the most controversial issues. This study aimed to examine the effect of resection distance from pylorus on % excess weight loss (EWL) during postoperative period, in patients who underwent LSG for morbid obesity.

methodsA total of 390 patients who underwent laparoscopic sleeve gastrectomy for morbid obesity were included in this retrospective study. Patients were allocated into one of the two groups based on the distance between antrum resection margin and pylorus: group A, ≤ 3 cm and group B, > 3 cm. Follow-up data for %EWS and nausea/vomiting as well as demographical and perioperative data were retrospectively reviewed and logistic regression analysis was done.

resultsFollow-up data up to 12 months were available for all patients, whereas 199 patients had follow-up data at 24 months. Shorter distance from pylorus was associated with higher %EWL throughout the treatment period (p < 0.001), evident from the first postoperative month (p = 0.013 for the first month, p < 0.001 for all other time points). The benefit extended up to 24 months in ≤ 3 cm group. However, nausea/vomiting was more frequent in the ≤ 3 cm group only at 1-month visit (15% vs. 4%, p < 0.001). In multivariate evaluations, while %EWL variable was taken as a dependent variable, time variable with DP × time interaction was statistically significant in the model.

conclusionsOur findings indicate that a short distance between resection margin and pylorus is associated with better and sustained %EWL in LSG. However, these patients seem to be more prone to nausea and vomiting in the early postoperative period. Further prospective large studies would help to define an optimal resection distance.
