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

objectiveTo summarize and analyze the clinical characteristics of patients diagnosed with hepatic portal venous gas (HPVG).

methodsThis was a single center retrospective observational study. All of the patients were diagnosed with HPVG. The patients were admitted to Peking University Third Hospital from January 2017 to January 2021. Demographic characteristics, clinical manifestations, laboratory tests, abdominal imaging, treatment of the primary disease, and clinical outcomes of the patients were collected via electronic medical records. The study was approved by institutional review board and the information of all the patients was kept de-identified.

resultsA total of seven cases were included in the study. The median age of the patients was 67 (63, 81) years. Six of the patients were male. The seven patients all presented with sudden onset of severe abdominal pain, which was the most common symptom. Six patients developed septic shock after admission. The signs of HPVG were detected by CT scans in all the patients, showing gas embolization. It might also be found as unique "aquarium sign" in abdominal ultrosonography. Four cases were caused by intestinal lesions, including acute volvulus, intestinal obstruction, and rectal abscess. Two were caused by ischemic bowel disease and the other one was caused by severe acute pancreatitis. The gas accumulation could disappear after effective anti-shock therapy and surgery (Cases 1, 2, and 6). Two patients had good postoperative outcomes, and one patient was discharged after non-surgical treatment. However, the prognosis was poor in the patients with intestinal ischemia necrosis accompanied by shock and multiple organ dysfunction (Cases 3, 4, 5, and 7 all died).

conclusionThe HPVG patients generally have acute abdominal pain and show up at Emergency Department. The prognosis depends on the potential cause of HPVG. The mechanism and clinical management for the appearance of gas in the portal vein is not well understood. Patients complicated with shock, ascites, and peritonitis may have intestinal necrosis, which indicates surgical intervention and higher mortality. CT is the preferred diagnostic method in standard clinical practice. Physicians need to have a comprehensive understanding of the proactive diagnostic strategy, and active treatment for the primary disease.
