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

backgroundVertical banded gastroplasty (VBG) has a relatively high failure rate in the long run, requiring revisional surgery in 30-65%. A common conversion option is to Roux-en-Y gastric bypass (RYGB), which can be performed laparoscopically or open. Current literature contains small cohorts and inconclusive results. Therefore, we set out to compare our series of open and laparoscopic VBG to RYGB conversions.

methodsAll conversions performed between 1996 and 2020 were included. Patients were divided into 3 groups based on conversion indication: weight recurrence (group 1), excessive weight loss (group 2), and eating/pouch difficulties (group 3). The primary outcome was postoperative complications according to the Clavien-Dindo (CD) classification. Secondary outcome was %total weight loss (%TWL) 1 to 5 years after revisional surgery.

resultsWe included 205 patients (84.9% female) of whom 105 underwent laparoscopic and 100 open VBG to RYGB conversion. Twenty-three short-term complications occurred in the laparoscopic group, with 16 > CD3a. In the open group, 33 complications occurred with 12 > CD3a. Overall complications were 33.3% in laparoscopic and 64% in open patients. There were no significant differences between the laparoscopic and open group in BMI (p = 0.76) and %TWL (p = 0.694) after 5 years. After 5 years, lost to follow-up was 97% in the open group. Twenty-eight percent of patients who reached follow-up in the laparoscopic group had available data.

conclusionsWe demonstrate that the overall complication rate is lower in the laparoscopic group compared to the open group. Regarding BMI, an improvement was achieved in both groups after 5 years.
