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

purposeSpleen-preserving distal pancreatectomy (SPDP) is performed for benign or low-grade malignant tumors of the pancreatic body and tail. The Warshaw technique (WT), involving the division of the splenic artery and vein, is associated with splenic infarction and gastric varices. Recently, SPDP with splenic artery resection and splenic vein preservation (SVP) has been introduced. However, its safety and feasibility remain unclear. This study compared the perioperative outcomes between the SVP and WT approaches.

methodsWe retrospectively reviewed the data on patients who underwent laparoscopic or robot-assisted SPDP between January 2019 and December 2024. Of these, seven patients underwent SVP and 24 underwent WT. The clinical outcomes, complications, and postoperative imaging findings were evaluated.

resultsThe baseline characteristics were comparable between the groups. The operative time, blood loss, postoperative inflammatory markers, and clinically relevant postoperative pancreatic fistula showed no significant differences. Contrast-enhanced CT on postoperative day 7 demonstrated splenic infarction in 2 of 4 SVP patients (50%) and 14 of 22 WT patients (63.6%, p = 0.625). Gastric varices were observed only in the WT group (22.7%, p = 0.555). Splenic vein thrombosis did not occur in the SVP group.

conclusionsThe SVP approach is thus considered to be safe and feasible, with perioperative outcomes comparable to WT. Larger studies with long-term follow-up are warranted.
