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 effects of bariatric surgery on anal continence are not known. Data about proctologic lesions are very rare and do not include clinical data. The aim of this prospective study was to evaluate anal continence and anal lesions before and after sleeve gastrectomy (SG).

methodsWe prospectively included all patients presenting for bariatric surgery consultation at Bichat-Claude Bernard University Hospital, Paris, France, between 20 April 2015 and 16 December 2017. The patients were evaluated with questionnaires, anorectal manometry and clinical examination before SG (at enrollment) and between 12 and 24 months after (SG). Anal incontinence was defined as a Vaizey score above 4.

resultsOf 118 enrolled patients, 98 had SG. The patients were mostly women (n = 99, 84.6%). Median patient age was 45 years (IQR 34-54 years). The median follow-up period after surgery among the 86 patients who completed follow-up was 15 months (IQR 12.5-17.3 months). There was no significant change in the prevalence of anal incontinence after SG (12.8% preoperatively vs 24.4% postoperatively, p = 0.06). The median Vaizey score was 4 (IQR 4-4) both before and after SG (p = 0.1). No patient had de novo anal incontinence but worsening of anal incontinence was noted in 10 patients. Manometry revealed significantly lower median resting pressure (29 mmHg [IQR 22-68 mmHg] vs 22 mmHg [IQR 15-30 mmHg], p = 0.0015) and maximal squeeze pressure (IQR 29-74 mmHg vs IQR 30-60 mmHg, p = 0.0008) after SG. Anismus was more frequent after SG and was associated with constipation and Bristol type 1-2 stool consistency. Quality of life was unchanged. Proctologic lesions were rare and were present in 11 patients (12%) at enrollment and in 2 (2.4%) at follow-up.

conclusionsSG affected clinical anal continence but not significantly, and manometric measurements for anal pressures were lower postoperatively. Proctologic lesions were rare in this study population.
