Does powered stapler improve the mechanical integrity of gastrojejunal anastomosis compared to the current techniques? Experimental study in
Article in Journal of minimal access surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundNumerous techniques have been described for fashioning gastrojejunostomy (GJ) in a Roux-en-Y gastric bypass. These include hand-sewn anastomosis (HSA) and mechanical anastomosis; the latter includes circular stapled anastomosis (CSA) or manual linear stapled anastomosis (mLSA). More recently, this list also includes powered linear stapled anastomosis (pLSA). The aim of this study was to analyse if addition of power to stapling would improve the integrity of GJ anastomosis in ex vivo porcine models. SUBJECTS AND
methodsThe present study included five groups - mLSA1, mLSA2, HSA, CSA, and pLSA. Sequential infusions of methylene blue-coloured saline were performed into the GJ models. Pressure readings were recorded till the point of leak denoting burst pressure (BP). Total volume (TV) and site of leak were recorded. Compliance was calculated from the equation ΔTV/ΔBP.
resultsDifferences in pouch and intestinal thickness were not statistically significant between the models. BPs were higher in the mechanical anastomosis groups, i.e., pLSA 21 ± 9.85 mmHg, CSA 20.33 ± 5.78 mmHg, mLSA1 18 ± 4.69 mmHg and mLSA2 11 ± 2.94 mmHg, when compared to HSA 9.67 ± 3.79 mm Hg, which was found to be statistically significant (Kruskal-Wallis test, P = 0.03). Overall, the highest BP was recorded for powered stapling followed by circular, and then, linear stapling; however, this difference was not statistically significant (P = 0.86). There was no statistically significant difference among groups with regard to compliance (Kruskal-Wallis test, P = 0.082).
conclusionDespite the limited number of samples, mechanical anastomosis showed a statistically higher BP when compared to HSA, suggesting better anastomotic integrity. The pLSA group showed promising results with the highest BP recorded among all groups; however, this did not reach statistical significance.
