Abstract:
The goal of this study was to determine if there was a difference in leak pressure between esophageal-esophageal anastomosis and esophageal-jejunal anastomosis when using cadaveric porcine tissue. Leak pressures were recorded for esophagealesophageal anastomosis (Group 1 [control group], n = 7), cranial esophageal-jejunal anastomosis (Group 2, n = 7), and jejunal-caudal esophageal anastomosis (Group 3, n = 6). Each anastomosis was performed using polydioxanone sutures in a simple interrupted pattern. Results were analyzed using one-way analysis of variance. Mean ± SD of the leak pressures for groups 1, 2, and 3 were 46.1 ± 15.9, 36.5 ± 13.6, and 50.9 ± 11.1 mmHg, respectively (p = 0.18). When the results from groups 2 and 3 were combined and compared to that for Group 1, the mean ± SD leak pressures were 46.1± 15.9 and 43.1± 14.2 mmHg, respectively (p = 0.67). These results provide preliminary evidence that the jejunum may be a suitable option for use in esophageal replacement surgery; however, future studies of in vivo factors influencing the integrity of esophageal-jejunal anastomoses, including histologic evaluation of esophageal-jejunal anastomosis healing, are needed.
