Surgical treatment and prognosis of type II congenital extrahepatic portosystemic shunts: A single-center experience of 31 cases.

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
Congenital extrahepatic portosystemic shunts (CEPS) are rare congenital vascular malformations characterized by an abnormal communication between the hepatic portal venous system and the systemic venous system. Type Ⅱ CEPS preserves partial portal venous blood flow and can usually be treated with conventional surgery rather than solely relying on liver transplantation. To determine the optimal surgical methods and complication management strategies for type Ⅱ CEPS patients, we retrospectively analyzed 31 predominantly adult patients with type Ⅱ CEPS, documenting their surgical approaches and the occurrence of postoperative complications. Five surgical approaches were employed: 11 patients underwent shunt occlusion with 5 cases of complications; 5 patients underwent splenic vessels ligation with 2 cases of complications; 5 patients underwent shunt occlusion combined with splenic artery ligation with 4 cases of complications; 8 patients underwent shunt occlusion combined with distal splenorenal shunt with 3 cases of complications; and 2 patients with lower extremity edema underwent inferior vena cava shunt bypass surgery, with no significant complications observed. In conclusion, surgery centering on the shunt occlusion demonstrates promising therapeutic value and remains the mainstay in the treatment of type II CEPS. Meanwhile, postoperative complications remain a concern, necessitating long-term monitoring and management.
