Redefining Staple Loading Pressures for Adequate Tissue Apposition in Laparoscopic Sleeve Gastrectomy

Background: Stomach tissue thickness (TT) and surgeon-selected closed staple height (CSH) are important factors in the formation of an adequate staple line during laparoscopic sleeve gastrectomy (LSG). Staples need to have a CSH that is appropriate for a given TT in order to avoid staple malformation that may lead to leak or bleeding. Prior studies characterizing compressed stomach TT have used a loading pressure of 8g/mm2 to mimic stapling conditions. We hypothesize that 8g/mm2 is an inadequate loading pressure for measuring stomach TT.
