Table 2.
Severity of postoperative complications among patient cohorts. The Clavien–Dindo classification was used to objectify the severity of postoperative complications among both patient cohorts. p-Values were calculated to analyze whether statistically significant difference between both stapler sizes was present. In addition, further analysis of patients with severe postoperative complications, here classified as CD ≥ IIIa, was performed.
