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 robotic platform in pancreatic disease has gained popularity in the hepatobiliary community due to significant advantages it technically offers over conventional open and laparoscopic techniques. Despite promising initial studies, there remains scant literature on operative and oncologic outcomes of robotic pancreaticoduodenectomy (RPD) for pancreatic adenocarcinoma.

methodsA retrospective review evaluated all RPD performed for pancreatic adenocarcinoma from 2008 to 2019 in a single tertiary institution. RPD cases were matched to open cases (OPD) by demographic and oncologic characteristics and outcomes compared using Mann-Whitney U test, log rank tests, and Kaplan-Meier methods.

resultsThirty-eight RPD cases were matched to 38 OPD. RPD had significantly higher lymph node (LN) yield (21.5 vs 13.5; p = 0.0036) and no difference in operative time or estimated blood loss (EBL). RPD had significantly lower rate of delayed gastric emptying (DGE) (3% vs 32%; p = 0.0009) but no difference in leaks, infections, hemorrhage, urinary retention ,or ileus. RPD had significantly shorter length of stay (LOS) (7.5 vs. 9; p = 0.0209). There were no differences in 30- or 90-day readmissions or 90-day mortality. There was an equivalent R0 resection rate and LN positivity ratio. There was a trend towards improved median overall survival in RPD (30.4 vs. 23.0 months; p = 0.1105) and longer time to recurrence (402 vs. 284 days; p = 0.7471). OPD had two times the local recurrent rate (16% vs. 8%) but no difference in distant recurrence.

conclusionsWhile the feasibility and safety of RPD has been demonstrated, the impact on oncologic outcomes had yet to be investigated. We demonstrate that RPD not only offers similar if not superior immediate post-operative benefit by decreasing DGE but more importantly may offer improved oncologic outcomes. The significantly higher LN yield and decreased inflammatory response demonstrated in robotic surgery may improve overall survival.
