Utility of routine postoperative imaging in adults undergoing primary ventriculoperitoneal shunts.

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
backgroundThere is currently no consensus on the usefulness of postoperative imaging after ventriculoperitoneal (VP) shunt insertion in adults. The aim of this study was to investigate the utility of routine postoperative imaging (CT head scans and radiographs) following primary VP shunt insertion in a general adult population treated at a tertiary neurosurgical centre.
methodsPatients undergoing primary VP shunt insertion between 2017-2021 were included. Actions taken based on routine postoperative imaging and need for subsequent shunt revision were recorded.
results236 patients were included. The median age was 63 years (range 17-90). There was a slight female preponderance (121/236, 51.3%). The median follow-up was 38.5 months (3.1 - 60.5 months). Acute intervention was employed in 9 patients (3.9%) on the basis of routine postoperative CT head scan. Routine postoperative radiographs did not result in reoperation. Around a quarter (28.8%) of patients had a shunt revision, most of whom underwent urgent primary shunt insertions. Postoperative ventricular catheter characteristics (position of shunt tip, tip relation to septum pellucidum, and intraventricular catheter distance) were not predictive of shunt revision. Surgical urgency (emergency vs. elective procedures) was associated with long-term shunt revision (OR = 2.80, 95% CI 1.42 - 5.53, p = 0.003).
conclusionsRoutine postoperative imaging rarely led to reoperation in adult patients undergoing primary VP shunt insertion. Patients undergoing emergency shunt insertions were at the highest risk for requiring revision.
