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

introductionAs the prevalence of sleeve gastrectomy (SG) continues to rise each year, so does the number of patients requiring conversion to a hypoabsorptive procedure due to suboptimal results. While various types of bypass surgeries have been studied, available literature on transit bipartitions (TB) remains limited.

methodsWe conducted a retrospective analysis of patients who underwent conversion of SG to TB at our institution between November 1, 2017 and March 30, 2022. Three TB techniques were evaluated: one anastomosis sleeve-ileal TB (OATB), sleeve-ileal loop TB with Braun jejunoileostomy (B-TB), and TB with a Roux-en-Y formed small bowel short circuit (RYTB). Additional percentage of excess weight loss (%EWLadditional), percentage of total body weight loss (%TWL), and resolution of obesity-related comorbidities were the primary outcomes, while adverse effects were analyzed to assess the safety of each procedure.

resultsOf the 482 SG-to-TB conversions performed by March 2024, 171 patients with a complete follow-up (FU) of 2 years were included and matched by sex, age, and Body Mass Index (BMI) at the time of conversion. The %EWLadditional for OATB, B-TB, and RYTB at 2 years FU was 50.1, 53.4 and 54.3, respectively, with no significant differences in weight loss outcomes over time. OATB patients experienced more long-term adverse effects and showed a higher rate of reoperation. CONCLUSIUON: TB after SG is a feasible and effective revisional procedure for achieving further weight loss and managing obesity-realated comorbidities. OATB, however, may be associated with a higher risk of long-term complications compared to other TB techniques.
