Abstract

OBJECTIVE To compare the leak pressure and amount of time required to perform closure for 2 double-layer esophagotomy closure techniques.

SAMPLE 28 intrathoracic esophageal segments harvested from 38 porcine cadavers.

PROCEDURES Longitudinal 3-cm esophagotomy incisions made in porcine cadaveric esophagi were closed with 2 double-layer closure techniques. Fifteen incisions were closed with a simple interrupted pattern, and 13 incisions were closed with a simple continuous pattern. Leak pressure, bursting wall tension, and closure time were compared between suture patterns by use of a t test or Mann-Whitney rank sum test.

RESULTS Median leak pressures differed significantly between segments closed with the simple interrupted pattern (16.0 mm Hg; range, 5.4 to 54.9 mm Hg) and the simple continuous pattern (38.7 mm Hg; range, 11.3 to 81.9 mm Hg). Median bursting wall tension differed significantly between the simple interrupted pattern (0.63 × 105 dynes/cm; range, 0.16 × 105 dynes/cm to 2.89 × 105 dynes/cm) and the simple continuous pattern (1.79 × 105 dynes/cm; range, 0.44 × 105 dynes/cm to 4.70 × 105 dynes/cm). Mean ± SD closure time differed significantly between the simple interrupted pattern (19.2 ± 2.0 minutes) and the simple continuous pattern (14.7 ± 1.5 minutes).

CONCLUSIONS AND CLINICAL RELEVANCE In the study reported here, double-layer simple continuous closure resulted in a higher median postoperative leak pressure and higher median postoperative bursting wall tension and could be performed more rapidly than the double-layer simple interrupted closure on these porcine cadaveric specimens.
