Modified Collard versus end-to-side hand-sewn anastomosis for cervical anastomosis after McKeown esophagectomy.
Article in Thoracic cancer, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAccording to previously published studies, esophagectomy with modified Collard anastomosis has been reported to have low incidences of anastomotic leak and stricture. However, the optional anastomotic method after esophagectomy is still controversial. We conducted this study to compare the incidence of postoperative anastomotic stricture formation and dysphagia over three years after an esophagectomy with modified Collard anastomosis (MC) or end-to-side (ETS) hand-sewn anastomosis. Meanwhile, the early postoperative anastomotic leakage and other complications, hospital stay and 30- and 90-day mortality were also evaluated.
methodsThe clinical data of 905 patients undergoing McKeown esophagectomy were retrospectively reviewed. The rate of postoperative stricture formation after three years was demonstrated by stricture-free survival which is the primary end-point of this study. The incidence of dysphagia, first time of onset of stricture and number of dilatations were also recorded during follow-up.
resultsThe incidence of anastomotic leak tended to be higher in the MC group compared with that in the ETS group (13.0% vs. 8.7%, P = 0.064). The rates of anastomotic stricture in the MC group were significantly less than in the ETS group (P = 0.004). The number of dilatations in the MC group were significantly greater than those in the ETS group (2.34 vs. 2.46, P = 0.011).
conclusionsA modified Collard cervical esophagogastric anastomosis was associated with lower rates of anastomotic stricture and dysphagia, compared with ETS hand-sewn anastomosis. However, the modified Collard anastomosis is accompanied by an increased anastomotic leakage rate.
