Surrogate measure of gut blood flow via superior mesenteric circulation on ultrasound in adults who underwent esophagectomy: A descriptive cohort study.
Article in JPEN. Journal of parenteral and enteral nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEarly enteral nutrition is recommended for critically ill patients. However, feeding an ischemic gastrointestinal tract with enteral nutrition may lead to gut necrosis. Although gut tolerance of enteral nutrition is assessed by various symptoms, none of them provide conclusive evidence of gut ischemia. We investigated the blood flow in the superior mesenteric artery and vein using ultrasonography after esophagectomy along with conventional physical findings.
methodsWe enrolled 30 patients who underwent esophagectomy at The University of Tokyo Hospital from October 2022 to July 2023. Superior mesenteric artery, vein, and common carotid arteries blood flow were measured during the preoperative fasting period and on postoperative days 1, 2, 3, 5, 7, and 9. The relationships between blood flow and physical findings were analyzed.
resultsSuperior mesenteric artery and vein blood flows were lower on postoperative day 1 than during the preoperative fasting period (superior mesenteric artery: 81% P = 0.03, superior mesenteric vein: 85% P = 0.01) but recovered to preoperative levels after postoperative day 2. Common carotid artery blood flow remained constant perioperatively. None of the physical findings observed correlated with the superior mesenteric artery and vein blood flows at any time point. Superior mesenteric artery and vein blood flows increased when enteral nutrition was initiated. No cases of gut necrosis were observed.
conclusionDespite the relatively severe insult, gut blood flow recovered promptly. As traditional indicators did not correlate with gut blood flow, routine measurement of superior mesenteric artery and vein blood flows may allow assessment of potential gut hypoperfusion after major surgery.
