Comparison of Two Automatic Staplers for Closing the Bronchial Stump after Pulmonary Resection

Abstract

The incidence of complications following pulmonary resection using an automatic stapler was studied in 348 consecutive patients. A parallel-jaw stapler with two staple lines was used in group A (133 males, 101 females, mean age 66 years) between 1990 and 1995, and a hinged-jaw stapler with three staple lines in group B (70 males, 44 females, mean age 67 years) in 1995-1997. The incidence of bronchopleural fistula was 0.4% (1 patient) in group A and nil in group B. The incidence of intraoperative air leak requiring interrupted suture closure was 4.7% (11 patients) in group A and nil in group B (p < 0.05). Postoperative bronchopleural fistula did not develop in any of the cases, and there was no mortality. For management of the bronchial stump after pulmonary resection, the newer device firing three rows of staples is superior to the two-row device.
