Influence of the Glissonean Pedicle Transection Approach in Spiegel Lobe-Preserving Left Hepatectomy on Spiegel Lobe Volume and Remnant Liver Functions.

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 extrahepatic surgical technique in liver resection can be divided into glissonean pedicle transection and glissonean separated transection approaches. In this study, we compared remnant liver function and liver regeneration involving the Spiegel lobe between these two approaches regarding Spiegel lobe-preserving left hepatectomy.
methodsWe enrolled 31 patients who underwent Spiegel lobe-preserving left hepatectomy for malignant hepatobiliary diseases between April 2008 and January 2020. The postoperative Spiegel lobe volume was measured using a volume analyzer at 3 and 6 months postoperatively.
resultsOf the 31 patients, 22 and 9 were included in the glissonean separated transection and glissonean pedicle transection groups, respectively. There was no significant between-group difference in the preoperative Spiegel lobe volume. However, the volumes at 3 and 6 months postoperatively were significantly larger in the glissonean pedicle transection group than in the glissonean transection group (29.92 mL vs. 13.00 mL; P < 0.001 and 28.43 mL vs. 15.01 mL; P < 0.001, respectively). There was no significant between-group difference in postoperative remnant liver function.
conclusionsThe postoperative Spiegel lobe volume was larger, and liver regeneration was better with the glissonean pedicle transection approach because of transection for Spiegel branch of the portal vein. It is desirable to preserve Spiegel branch in possible cases when surgeons select the glissonean separated transection approach based on the location and size of the tumors.
