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

backgroundLaparoscopic sleeve gastrectomy (LSG) has become a primary stand-alone procedure for weight-loss surgery. The standard technique for LSG involves several small abdominal incisions. The single port instrument delivery extended reach (SPIDER(®)) surgical system has been introduced as a single site modality. This technique has been described previously; however, weight-loss outcomes of SPIDER(®) sleeve gastrectomy have not been compared to multi-port LSG.

methodsWe performed a retrospective review of a prospectively collected database. All cases were performed by a single surgeon between August 2011 and September 2013. Thirty-two patients underwent SPIDER(®) sleeve gastrectomy, while 30 underwent LSG. Primary outcomes were change in BMI and percent excess weight loss (%EWL) at 6 months post-operatively. Secondary outcomes included: operative time, estimated blood loss (EBL), and complications.

resultsThere were no demographic differences between cohorts except initial BMI (SPIDER(®) = 42.1, LSG = 46.5, p < 0.001). Mean %EWL at 6 months post-operatively was higher in the SPIDER(®) cohort (59.1 vs. 48.3 %, p < 0.005). Similarly there was a lower mean BMI at 6 months post-operatively in the SPIDER(®) cohort (31.1 vs. 35.5, p < 0.0001). The net change in BMI for each cohort was equivalent (SPIDER(®) = 11.1, LSG = 11.0, p = 0.95). Mean operative time was longer in SPIDER(®) cases (104.6 vs. 90.7 min, p < 0.02), while EBL was equivalent (32.1 vs. 34.3 mL, p = 0.56). There was one post-operative hemorrhage requiring laparoscopic clot evacuation in the SPIDER(®) cohort, and one wound infection in the LSG cohort.

conclusionsSPIDER(®) sleeve gastrectomy is not inferior to LSG with regard to decrease in BMI and %EWL at 6-months post-operatively. The higher %EWL observed in the SPIDER(®) cohort is likely due to patient selection bias. This study demonstrates that the SPIDER(®) technique is a viable alternative to LSG with similar weight-loss outcomes.
