An ex vivo comparison of jejunal transection angles and the effect on lumen diameter following end-to-end jejunojejunal anastomoses.

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
objectiveTo evaluate three different jejunal transection angles for end-to-end jejunojejunostomies, comparing construction time, lumen size, and suture number. STUDY
designEx vivo cadaver study. SAMPLE POPULATION: Eight euthanized horses each had three mid-jejunal specimens harvested.
methodsJejunal segments were assigned to one of three groups (A30, A45, and A60) and transected at 30, 45, or 60°, respectively. Following transection, a standardized handsewn single-layer interrupted modified Lembert anastomosis was performed, and construction time and number of sutures placed were recorded. Anastomotic index (AI) was calculated. Statistical analysis was performed using a one-way ANOVA. Statistical significance was set at p < .05.
resultsTransected jejunal lengths increased as the transection angle decreased (p < .001). Anastomoses construction time was not different between groups (p = .301). The number of sutures required to complete the anastomosis was higher (p = .026) for A30 compared to A60 but was not different between A60 and A45 or A45 and A30 (p > .333). Mean AI were 93.37, 114.29, and 135.07 for groups A60, A45, and A30 and the AI increased as the transection angle decreased (p < .001).
conclusionA 60° transection angle reduced lumen size at the anastomosis but a 45 and 30° transection angle resulted in an increased lumen size at the anastomosis. The 45° angle did not increase the number of sutures required. The 30° angle significantly increased the number of sutures required. CLINICAL SIGNIFICANCE: A 45° angle of transection does not result in increased surgical time or number of sutures placed. Further investigation is required to determine the ideal angle of transection.
