Utility of routine postoperative upper gastrointestinal swallow studies following laparoscopic one anastomosis gastric bypass.

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.
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
backgroundLaparoscopic one anastomosis gastric bypass (OAGB) has grown in popularity in recent years for the treatment of morbid obesity. Despite routine practice, the utility of early postoperative upper gastrointestinal (UGI) swallow studies to detect complications following OAGB has been questioned.
aimTo evaluate the effectiveness and cost-efficiency of performing routine UGI studies on the first postoperative day (POD) after OAGB.
methodsA retrospective cohort analysis of a prospectively collected database was conducted to identify all consecutive patients who underwent OAGB between January 2019 and July 2022. Patient demographics, operative data, and postoperative complication rates were analyzed. Reports from all imaging studies were retrospectively reviewed, and complications were recorded. The institutional review board waived the requirement for informed consent.
resultsA total of 385 patients were included. All patients had an iodine-based contrast swallow study on the first POD. Abnormal findings were observed in 4 patients (1%), none of which were correlated with postoperative complications. Two patients (0.5%) required reoperation due to complications although both had normal UGI study results. Sensitivity and positive predictive value of UGI studies for detecting complications were 0%, while specificity and negative predictive value were 99% and 98%, respectively. Based on hospital charges the overall cost of all the UGI swallow studies performed in our study was 95865 USD.
conclusionThe study findings showed that performing routine UGI swallow studies on the first POD after laparoscopic OAGB is ineffective in detecting complications and is not cost effective. Normal UGI studies might mislead clinicians in the postoperative period and thus should be omitted in favor of close clinical monitoring.
