Role of Collateral Venous Circulation in Prevention of Sinistral Portal Hypertension After Superior Mesenteric-Portal Vein Confluence Resection during Pancreaticoduodenectomy: a Single-Center Experience.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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 ligation of the splenic vein (SV) during pancreaticoduodenectomy (PD) may result in sinistral portal hypertension (SPH). This study aimed to identify the collateral pathways that formed postoperatively and evaluate the impact of omentum and arc of Barkow preservation in PD.
methodsPatients who underwent PD between January 2013 and May 2018 at the Second Affiliated Hospital of Zhejiang University were enrolled in this retrospective study. PD was performed with preservation of the greater omentum and arc of Barkow. Venous collaterals, spleen size, and platelet count were evaluated before and after surgery.
resultsIn total, 330 patients underwent PD, of whom, 43 patients who underwent superior mesenteric vein (SMV)/portal vein (PV) reconstruction and splenic vein (SV) ligation were selected. No patient developed severe gastrointestinal bleeding. Three collateral routes were identified: the left gastric route, the colic marginal route, and the first jejunal route. Seventeen patients developed splenomegaly. Twenty-three patients developed thrombocytopenia. However, none of them developed gastrointestinal bleeding or other clinical complaints.
conclusionAlthough subclinical SPH developed after SV ligation, postoperative gastrointestinal bleeding was uncommon.
