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

backgroundLaparoscopic subtotal cholecystectomy (LSC) is a safe bailout procedure in situations when dissection of "critical view of safety" is not possible. After the proposed classification of subtotal cholecystectomy into "fenestrating" and "reconstituting" techniques in 2016, a comparative review of the outcomes of both methods is timely.

methodsA literature search of the PubMed, Cochrane Library, and Web of Science database was conducted up to January 31, 2020 for studies that reported LSC. Studies reporting LSC only in patients with Mirizzi syndrome or xanthogranulomatous cholecystitis were excluded. Our analysis includes 39 studies with 1784 cases of LSC. We report a comparison of outcomes between reconstituting and fenestrating LSC on 1505 cases [935 reconstituting (62.1%) and 570 fenestrating (37.9%)].

resultsFollowing LSC, the rate of open conversion is 7.7%, hemorrhage is 0.4%, bile duct injury is 0.3%, bile leak is 15.4%, retained stone is 4.6%, subhepatic or subphrenic collection is 2.9%, superficial surgical site infection is 2.0% and 30-day mortality is 0.2%. 8.8% of patients required postoperative endoscopic retrograde cholangiopancreatography (ERCP), 1.1% required percutaneous intervention, and 2.2% required reoperation. Compared to reconstituting LSC, fenestrating LSC has a higher incidence of open conversion (n = 58, 10.2% vs. n = 43, 4.6%, p < 0.001), retained stones (n = 38, 6.7% vs. n = 38, 4.1%, p = 0.0253), subhepatic or subphrenic collections (n = 33, 5.8% vs. n = 13, 1.4%, p < 0.001), superficial surgical site infections (n = 18, 3.2% vs. n = 14, 1.5%, p = 0.0303), postoperative ERCP (n = 82, 14.4% vs. n = 62, 6.6%, p < 0.001), and need for reoperation (n = 20, 3.5% vs. n = 12, 1.3%, p < 0.001).

conclusionsAlthough reconstituting LSC has better outcomes, both techniques are complementary. Intraoperative findings and surgical expertise impact the choice.
