Evaluation of Alternate Laparoscopic Stapling Device for Bariatric Surgery

Area of Science:

• Bariatric Surgery
• Surgical Technology
• Gastrointestinal Surgery

Background:

• Laparoscopic bariatric surgery has advanced, reducing complication rates.
• Surgical stapling devices are integral for gastric tissue resection and anastomosis.
• This study compares complication rates of two distinct stapling devices.

Purpose of the Study:

• To assess and compare complication rates and clinical outcomes.
• Evaluate two approved laparoscopic surgical stapling devices in bariatric procedures.

Main Methods:

• Retrospective comparison of clinical outcomes for patients using laparoscopic surgical stapling device A (AEON Endostapler) versus device B (Endo GIA with Tri-Staple Technology).
• Data collected from April 2019–December 2020 (device A) and January 2017–September 2018 (device B).
• Analysis included sleeve gastrectomy, Roux-en-Y gastric bypass (RYGB), and single anastomosis duodenoileostomy with gastric sleeve.

Main Results:

• 814 patients used LSSD-A, 1034 used LSSD-B.
• No stapler-related complications occurred in the last 13 months of the LSSD-A period.
• One staple line leak occurred with LSSD-B; RYGB patients using LSSD-A had fewer complications, transfusions, and reoperations for bleeding.

Conclusions:

• Both LSSD-A and LSSD-B demonstrated safety and efficacy in laparoscopic bariatric operations.
• Comparable clinical performance was observed for sleeve gastrectomy and single anastomosis duodenoileostomy with gastric sleeve.
• Laparoscopic RYGB showed statistically significant differences in complication rates favoring LSSD-A.
