Portal thrombosis after surgical treatment of schistosomatic portal hypertension.

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
objectiveSeveral studies have investigated the correlation between the effects of different surgical treatments and laboratory exams for schistosomal portal hypertension, especially concerning portal system thrombosis. The etiopathogenic factors of this thrombosis are not fully understood. In this study, the correlation between surgical treatment for schistosomal portal hypertension and the occurrence of postoperative portal system thrombosis was investigated.
methodsA total of 61 patients who underwent surgical treatment for schistosomal portal hypertension were distributed into four groups: Patients in Group 1 (n=12) underwent portal variceal disconnection associated with splenic artery ligation and spleen preservation. Patients in Group 2 (n=20) underwent portal variceal disconnection and total splenectomy. Patients in Group 3 (n=20) underwent portal variceal disconnection with subtotal splenectomy, preserving the upper splenic pole supplied by the splenogastric vessels. Patients in Group 4 (n=9) underwent portal variceal disconnection with total splenectomy and autogenous splenic implants on the greater omentum. Late postoperative portal vein thrombosis was diagnosed using Doppler ultrasound.
resultsOver the 10-year follow-up, portal vein thrombosis occurred in 26 operated patients (42.6%), with no significant difference observed among the four surgical groups (p=0.217). Most of the thrombi only partially occluded the portal system veins. All the patients presented with a thrombus inside the portal vein. There was no difference in hematological and biochemical tests between groups with or without portal vein thrombosis.
conclusionsPortal vein thrombosis is often observed in the late postoperative period, irrespective of the surgical treatment employed, and is not associated with patient characteristics or any hematological and biochemical tests.
