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

purposePostoperative pancreatic fistula (POPF) remains a major complication following pancreaticoduodenectomy (PD). Although pancreaticogastrostomy (PG) has been suggested to be associated with a lower risk of POPF in some studies, optimal criteria for postoperative drain management in PG cases remain unclear.

methodsThis single-institution retrospective study analyzed 195 consecutive PD cases involving a soft pancreas and PG. New criteria for safe drain removal were developed based on independent risk factors identified through a multivariate analysis. A prospective validation study was then conducted in 70 consecutive soft pancreas cases to assess the safety and efficacy of these criteria.

resultsIn the retrospective cohort, white blood cell count (WBC) > 8200/µL on postoperative day (POD) 5, drain fluid amylase (DFA) > 160 U/L on POD 5, and delayed nasogastric (NG) tube removal were identified as independent risk factors. The criteria for drain removal were defined as: WBC ≤ 8200/µL, DFA ≤ 160 U/L, and NG tube removal by POD5. In the validation cohort, 42 out of 70 patients met the criteria; none developed Clavien–Dindo grade IIIa or higher complications after drain removal. The incidence of delayed gastric emptying (DGE) was significantly lower in the post-validation cohort than in the pre-validation cohort (p < 0.01).

conclusionIn patients undergoing PG with a soft pancreas, application of the new criteria enables safe early drain removal and may help reduce the incidence of DGE.
