Constructs were randomly assigned to have the serosal patch anastomosed to the duodenal segment by a simple continuous or simple interrupted suture pattern. The pressure at which the first leakage was observed and the maximum pressure obtained during testing were recorded and compared between suture patterns.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Initial leakage pressure was significantly higher with the simple interrupted pattern (mean \u00b1 SD, 68.89 \u00b1 5.62 mm Hg), compared with the simple continuous pattern (59.8 \u00b1 20.03 mm Hg). Maximum intraluminal pressures did not significantly differ between the simple interrupted (91 \u00b1 8.27 mm Hg) and simple continuous patterns (90.7 \u00b1 16.91 mm Hg). All constructs, regardless of suture pattern, withstood supraphysiologic pressures.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s005\">\n<jats:title>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Jejunal serosal patches adequately sealed large, open duodenal defects and prevented leakage in these constructs. Constructs with simple continuous or simple interrupted suture patterns withstood physiologic and supraphysiologic intraluminal pressures, although constructs with a simple interrupted suture pattern initially leaked at higher pressures.
