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

objectiveIn the course of laparoscopic Roux-en-Y gastric bypass (LRYGB), a tight gastroenterostomy (GE) may lead to higher weight loss but possibly to an increase of local complications such as strictures and ulcers. Different operative techniques for Roux-en-Y reconstruction may also influence the rate of internal hernias, a typical late complication of LRYGB. The objective of this study was to compare weight loss, rates of strictures, internal hernias, and ulcerations of linear versus circular stapler anastomosis.

methodsRetrospective analysis of prospectively collected data in a 3:1-matched pair study. A total of 228 patients with a minimal follow-up of 2 years were matched according to BMI at baseline, age, and gender. The follow-up rate was 100 % at 1 and 2 years postoperatively; the mean follow-up time was 3.8 ± 1.63 years. In group C (circular), 57 patients were operated with a 25-mm circular stapler technique (average BMI 44.7 ± 5.18 kg/m(2), age 44.1 ± 10.8 years, 80.7 % female). In group L (linear), 171 patients were operated using a linear stapler (approximately 30 mm, average BMI 43.8 ± 5.24 kg/m(2), age 43.7 ± 12.5 years, 70.8 % female). A propensity score matching and a logrank test were used for statistical analysis.

resultsThe average excessive BMI loss (EBMIL) after 1 year was not statistically different (70.6 ± 20.2 % in group C vs 72.5 ± 20.4 % in group L) as well as after 2 years (71.6 ± 22.5 % in group C vs 74.6 ± 19.6 % in group L). The average operation time was 155 ± 53 min in group C and 109 ± 57 min in group L (p = 0.0001). In group L, patients had significantly lower overall stricture rates at the GE compared to group C (0 [0 %] vs. 4 [7 %], p = 0.0004), a lower rate and severity of internal hernias (10 [5.8 %] vs. 7 [12.3 %] p = 0.466), and equal local ulcerations rates (3 [1.8 %] vs. 1 [1.8 %] p = 0.912).

conclusionLinear stapler anastomosis in LRYGB compared to circular anastomosis leads to equal weight loss and less strictures. The lower rate of internal hernias in linear stapler anastomosis was not significantly different.
