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

backgroundThe most common bariatric procedure in Australia is laparoscopic adjustable gastric banding (LAGB). Although successful, there is a substantial long-term complication and failure rate. Band removal and conversion to Roux-en-Y gastric bypass (RYGB) can be an effective treatment for complicated or failed bands. There is increasing evidence supporting good weight loss and resolution of band-related complications after conversion.

methodsA prospective database of all bariatric procedures is maintained. Patients having revision of LAGB to RYGB between December 2007 and April 2011 were included in this study. Indications for surgery, operative details, morbidity and mortality, weight loss data, and post-operative symptoms were recorded.

resultsEighty-two patients were included. Indications for surgery were inadequate weight loss (n = 42), adverse symptoms (reflux = 8, dysphagia = 2), and band complications (band erosion = 7, band sepsis = 1, band slip = 11, esophageal dilatation = 11). Seventy-eight percent of procedures were completed in a single stage and 96.3% laparoscopically. There was no 30-day mortality. Total morbidity was 46.3% (minor complications = 32.9%, major complications = 13.4%). Median BMI was 43 kg/m(2) pre-RYGB and 34 kg/m(2) after 12 months. All patients with adverse band-related symptoms had resolution.

conclusionsLAGB has a considerable complication and failure rate. Conversion of these patients to RYGB results in further weight loss and resolution of adverse symptoms. This is a challenging procedure, but can usually be performed in a single stage with acceptable morbidity and mortality. These patients should be treated in high-volume, subspecialty bariatric units.
