Single-use staplers (SUS) are widely used surgical instruments that contribute to resource consumption and waste generation, whereas multi-use staplers (MUS) can greatly reduce the environmental impact of surgery. The staple lines are often reinforced with buttressing material to prevent leaks and bleeding. We explore current clinical practice and environmental concerns regarding stapling and buttressing, as well as the environmental impact of staple line buttressing in sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). Furthermore, we extend this analysis by taking packaging material and the lithium in power supplies into consideration.Materials and Methods: A survey of bariatric surgeons was conducted to assess stapler and buttressing use in clinical practice. We deconstructed and analyzed the product and packaging composition of a commonly used SUS with separate staple line reinforcement (Echelon Flex™ with Echelon Endopath™, Ethicon) and MUS (Signia™ with Tri-Staple™ reinforced reloads, Medtronic), where the buttressing material was delivered separately or already incorporated in the reload cartridge, respectively. Both systems were compared regarding total waste generation, resource use (determined as total material requirement), and greenhouse gas emission caused by their lithium content.Results: 60 mm cartridges were most frequently used in bariatric surgery, and 67% of surveyed surgeons applied staple line reinforcement. MUS with pre-attached buttressing resulted in a reduction of waste, material consumption, and greenhouse gas emissions compared to SUS with separate buttressing: they reduced product waste by 40% (SG and RYBG), packaging waste by 60% (SG) and 57% (RYGB), resource consumption by more than 90%, and greenhouse gas emissions related to the lithium in the batteries by 99.7%. Preloaded buttressing produced less waste than separate buttressing per stapler firing.Conclusion: The environmental impact of surgery can be greatly reduced by using MUS with pre-attached buttressing rather than SUS with separate buttressing.Keywords: circular economy, staple line reinforcement, reuse, resource efficiency, bariatric surgery, healthcare economics
