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

backgroundPlanned pancreatoduodenectomy (PD) for pancreatic adenocarcinoma (PDAC) can be aborted due to intraoperative findings. There is little guidance regarding the need for prophylactic bypass following an aborted PD to prevent symptomatic biliary obstruction or gastric outlet obstruction (GOO) postoperatively. The aim of this study was to characterize postoperative interventions and postsurgical survival in patients following aborted PD.

methodsPatients with PDAC treated with neoadjuvant therapy and staging laparoscopy prior to planned PD between 2010 and 2015 were reviewed for aborted PDs. Data on postoperative biliary obstruction, GOO, procedural intervention, and postsurgical survival were analyzed.

resultsOf 271 planned PDs, 47 (17.3%) were aborted. Thirty-six patients had ≥ 2 months of follow-up data and were included. Six patients underwent hepaticojejunostomy and nine patients underwent gastrojejunostomy at the time of the aborted PD. Sixteen of 30 patients (53%) without a surgical biliary bypass required endoscopic intervention, but none required palliative surgery. Ten of 27 patients (37%) without an operative gastrojejunostomy required intervention, but none required palliative surgery. Endoscopic or percutaneous therapy was required to treat 13/16 (81%) patients who presented with postoperative biliary obstructions and 6/10 (60%) of GOOs. Median survival following aborted PD was 13.3 months (CI 8.9-17.7). There were no differences in survival when comparing patients who developed a biliary obstruction (p = 0.92) or GOO (p = 0.90) to asymptomatic patients.

conclusionsFollowing aborted PD, patients commonly develop obstructive symptoms. However, these symptoms can generally be managed without surgical intervention. In asymptomatic patients, preemptive surgical bypasses are not required at the time of aborted PD.
