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

backgroundReversal of Roux-en-Y gastric bypass (RYGB) to normal anatomy (NA) is mandated in selected cases. However, reversal operations are associated with high complication rates and long operative times. In this study, we present the functional reversal (FR) as a novel method and an alternative to reversal to NA in treating the otherwise intractable symptoms rarely occurring after RYGB.

methodsThis is a retrospective cohort study of RYGB-patients with symptoms resistant to non-surgical treatment. Placement of gastrostomy tube for surgical evaluation and optimization of patients was usually done before FR. Resolution of symptoms was assessed along with efficacy and safety of the procedure. Achieved results were compared with data from the literature pertaining to reversal to NA. SETTINGS: High-volume bariatric center, Norway.

resultsTen patients underwent FR. Mean follow-up after reversal was 18.4 months. Symptoms leading to operation improved in all patients. Eight patients suffered from hypoglycemia; resolution was seen in six and improvement of symptoms in the remaining two. Food intolerance, early dumping, nausea, postprandial abdominal pain, and malnutrition were alleviated in all patients. One leak was seen. Mean surgical time was 35.2 min. Total weight loss (TWL) and excess weight loss (EWL) after index RYGB were reduced 4.5% and 17.8%.

conclusionFunctional reversal looks promising as an alternative to reversal to normal anatomy as it is technically simpler and safer and seems at least as effective in treating otherwise refractory symptoms.
