Outcomes of Staple Line Reinforcement Following Robotic Assisted Sleeve Gastrectomy Based on MBSAQIP Database.

Area of Science:

• Bariatric Surgery
• Surgical Techniques
• Quality Improvement

Background:

• Robotic-assisted sleeve gastrectomy (RA-SG) is a common bariatric procedure.
• Staple line reinforcement (SLR) techniques aim to reduce complications.
• Outcomes of different SLR methods require further evaluation.

Purpose of the Study:

• To evaluate the impact of staple line reinforcement (SLR) on outcomes after robotic-assisted sleeve gastrectomy (RA-SG).
• To compare outcomes based on different SLR methods: oversewing (OS), buttressing (BR), both, or neither.
• To analyze data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.

Main Methods:

• Retrospective analysis of 16,494 patients who underwent RA-SG in 2019 from the MBSAQIP database.
• Patients were grouped by SLR status: OS, BR, both, or neither.
• Primary outcomes included bleeding, organ space infection (OSI), and adverse events (AEs). Secondary outcomes included operative time, length of stay, readmissions, and conversion rates.

Main Results:

• No statistically significant difference in postoperative bleeding was observed between BR, OS, and no reinforcement.
• Oversewing (OS) was associated with significantly longer operative times compared to buttressing (BR) alone.
• No significant differences were found in organ space infection (OSI) or adverse events (AEs) across SLR groups.

Conclusions:

• Staple line reinforcement (SLR) does not significantly affect bleeding, OSI, or AEs in RA-SG based on 2019 MBSAQIP data.
• Oversewing (OS) is linked to increased operative time, suggesting buttressing (BR) may be more efficient.
• Further research may explore long-term outcomes and cost-effectiveness of different SLR techniques.
