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

backgroundAbdominal pain is the most frequent cause of hospital admission after Roux-en-y gastric bypass (RYGB). Among numerous possible underlying causes, internal hernias represent one of the most peculiar and insidious conditions, setting challenging diagnostic and therapeutic problems for the surgeon. The aim of this study is to analyze aspecific abdominal pain incidence and characteristics after RYGB, discriminating peculiar aspects suggestive of internal hernias.

methods13 patients submitted to internal hernia repair after laparoscopic antecolic RYGB and a group of 49 controls (non-complicated RYGB) have been assessed using a specific questionnaire. Overall aspecific abdominal pain incidence and characteristics have been analysed. Typical pain traits and predisposing conditions for internal hernias have been investigated.

results33% of controls reported aspecific abdominal pain after RYGB, mainly early postprandial, deep, remittent, colicky, located in the upper left abdomen. 77% of the case patients reported prodromal episodes of pain similar to the controls. The only significant differences between prodromal and acute episodes were pain intensity and quality (continuous). Excess weight lost at 3 months significantly correlated with internal hernia occurrence (p: 0.002).

conclusionsBased on abdominal pain characteristics, we can reasonably postulate the presence of remittent bowel torsions (remittent internal hernia) in many patients after antecolic RYGB, only occasionally complicating. Therapeutic management of these cases remains controversial, being laparoscopic exploration a reasonable option when symptomatology is suggestive.
