Experimental study of anterior wall sliding oblique suture technique in supermicrosurgery.

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
The study aimed to compare the Anterior Wall Sliding Oblique Suture Technique with the conventional vertical needle insertion technique in terms of feasibility and reliability for microvessel anastomosis. Forty male Wistar rats were used in this study. The rats were randomly divided into four groups according to the diameter of the median caudal artery (MCA) and these two methods. These two technologies were used to compare the duration of the surgery, one-time anastomotic patency rates, and delayed patency rates (7 days after the operation). An additional histological study was performed to assess the stenosis and destruction of vessels. All rats survived the surgical anesthetic procedure. The Anterior Wall Sliding Oblique Suture Technique was faster than the conventional technique for supermicrosurgery. Results showed that Group B had a significantly faster anastomosis time (23.8 min ± 2.7 vs. 19.2 min ± 2.0, P < 0.01). Group A1 had a higher one-time anastomotic patency rate (90%) than Group A2 (70%), while Group B2 (80%) had a significantly higher rate than Group B1 (20%) (P = 0.023). Delayed patency rates were also different between groups, with Group A1 having 100% and Group A2 having 50% (P = 0.033), while Group B1 had 30% and Group B2 had 90% (P = 0.020). These results showed that the new method ensured quality in supermicrosurgery, especially in the microvascular group in the histological study. The Anterior Wall Sliding Oblique Suture Technique is more effective than the conventional vertical needle insertion technique for supermicrosurgery. It reduces the operation time and improves the patency rate of vascular anastomosis. Therefore, it can be considered a reliable and effective method when dealing with the microvascular.
