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

backgroundEn bloc esophagectomy results in higher lymph node (LN) retrieval than standard esophagectomy. Minimally invasive esophagectomy (MIE) has gained traction due to improved short-term outcomes, but many large series report LN yields well below the international benchmark of 23. We sought to determine if an established approach to open en bloc resection can be safely transferred to MIE using LN yield as a quality benchmark.

methodsAn open approach to en bloc esophagectomy (OE) was established over 5 years (~ 300 cases) before en bloc MIE was introduced in 2010. Patients undergoing curative-intent en bloc Ivor-Lewis and McKeown esophagectomy for cancer from 2010 to 2019 by a single surgeon with formal minimally invasive surgery training were identified from a prospectively collected database. Mann-Whitney U and χ

resultsA total of 269 esophageal resections met inclusion criteria [193(72%) OE; 76(28%) MIE]. Age, sex, BMI and comorbidities were comparable between groups. Tumors were larger and more often locally advanced in OE. Median LN retrieval was sufficient by international standards in both groups [OE:34(27-46); MIE:28(22-39); p = 0.01]. "Failures" occurred in 33(17%) of OE and 12(16%) MIE cases (p = 0.63). No learning effect was observed for LN yield. R0 resection rate was comparable [OE:191(99%); MIE:73(96%); p = 0.90]. Operative time was longer for MIE [275(246-300)] than OE [240(210-270) minutes], p < 0.0001, while estimated blood loss (OE:350(250-500)mL; MIE:300(200-400)mL; p = 0.02] and length of stay [OE:8(6-13); MIE7(6-9) days; p = 0.02] were higher for OE. Morbidity and mortality were comparable between groups and LN yield did not impact survival.

conclusionsUnder appropriate conditions, an established approach to open en bloc esophagectomy can be safely transferred to MIE without compromising surgical quality.
