Adult Left Liver Transplantation With Mesocaval Shunt With Porto-Mesenteric Disconnection: Long-Term Outcome.

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
Aiming to decrease portal venous pressure and to minimize the risk of small-for-size syndrome when using a partial liver graft for liver transplantation (LT), surgical techniques modulating venous portal inflow have been proposed. We report here our experience on the long-term outcome after adult left split LT with mesocaval shunt (MCS) with porto-mesenteric disconnection (PMD). Between March 1996 and March 2010, 33 adult patients underwent LT from a full-right/full-left SLT for two adult recipients; portal vein inflow modulation through a MCS with PMD was realized in 10 cases. The study population consisted of 13 left liver and 15 right liver recipients who survived more than 1 year without retransplantation. The technique of mesenterico-portal disconnection with MCS which allowed to decrease the mean portal vein pressure to 14.2 mm Hg, was applied in six recipients who survived more than 1 year without retransplantation: five males and one female, with a mean age of 60 years (range: 53-66) who all received a left split graft, with a mean weight and GRWR of 562 g (range: 430-740) and 0.79% (range: 0.61-0.98), respectively. During follow-up, four patients with MCS (4/6) experienced hyperammonemic encephalopathy, after a mean delay of 9.1 ± 7.9 years after LT (ranging 2.6-20.1). The outcome was favorable with symptomatic treatment with lactulose ± rifaximin in all cases except one, who underwent surgical closure of the shunt. In conclusion, our results emphasize that portal vein inflow modulation through MCS during LT can be complicated by late occurrence of hyperammonemic encephalopathy.
