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

purposePseudoaneurysm (PA) after pancreaticoduodenectomy (PD) is a harmful complication due to postoperative pancreatic fistula. However, the preventive method for PA is unclear. This study aimed to assess the risk factors for PA after PD and to evaluate the clinical features of patients with PA.

methodsMedical records of 54 patients who underwent PD and developed clinically relevant postoperative pancreatic fistula (POPF) were retrospectively reviewed. We evaluated postoperative computed tomography (CT) findings, including the perianastomotic fluid collection (PFC) location on postoperative day 4. Perioperative findings and postoperative CT findings were compared between patients with and without PA after PD.

resultsThe PA group included nine patients (17%). The median postoperative day of diagnosis of PA was 17 (range, 7-33). The PA locations were the gastroduodenal artery stump (n = 3), dorsal pancreatic artery (DPA) stump from the common hepatic artery (n = 4), DPA stump from the replaced right hepatic artery (n = 1), and inferior pancreaticoduodenal artery stump (n = 1). The prevalence of falciform ligament wrap to the hepatic artery was lower (33% vs. 78%, p = 0.014) and superior PFC prevalence was higher (100% vs. 58%, p = 0.019) in the PA group than in the non-PA group. Superior PFC reached the dorsal part of the caudate lobe of the liver in all patients with PA. Furthermore, all PAs occurred at the arteries that could not be wrapped by the falciform ligament.

conclusionPrevention of superior PFC and falciform ligament wrapping may reduce PA occurrence after PD with clinically relevant POPF.
