Is staple line reinforcement still needed on contemporary staplers? A benchtop analysis.
Article in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundStaple line reinforcement (SLR) is commonly used in bariatric surgeries to reduce leaks and bleeds. With the evolution of staplers, the need for buttressing with the latest surgical stapling technology is in question. The efficacy of GORE® SEAMGUARD® (G-SLR) to improve staple line strength based on an established measure of burst pressure was evaluated. A benchtop test on synthetic tissue evaluated the pressure required for staple line leak across surgical staplers with and without G-SLR.
methodsStaple lines on a consistent thickness synthetic bowel were pressurized to the point of failure (burst pressure) among Ethicon®, Intuitive®, and Medtronic® surgical staplers with and without G-SLR. Burst pressure and leak location (through the staple line [TTSL] or through the staple [TTS], on the anvil or cartridge side) were recorded. Visual confirmation of a leak concluded each test.
resultsThe pooled mean burst pressure for G-SLR was greater (p < 0.05) by 0.494 pounds/square inch compared with no reinforcement with no meaningful differences among staplers. Leak failures were primarily TTS (91.7%) and equally distributed between reinforcement groups with more leak failures on the cartridge side with G-SLR and on the anvil side for non-SLR group. Leaks occurred across the length of staple lines with no discernable pattern.
conclusionEmploying a buttressing material strengthens the staple line, as measured by burst pressure, and may reduce the risk for staple line failure. This benchtop study of G-SLR with three commonly used surgical staplers demonstrated a significant increase in burst pressures among the studied stapling devices.
