Tracheal and cricotracheal resection for laryngotracheal stenosis: experience in 54 consecutive cases.

Objective: Partial tracheal resection (Küster operation (KO)) and cricotracheal resection (Pearson operation (PO)) are currently the standard operative techniques in the curative treatment of tracheal and cricotracheal stenosis, respectively. This study aims to analyze the outcomes of tracheal and cricotracheal resection when a specific protocol is applied.

Methods: Between 1990 and 2004 we treated 54 patients with laryngotracheal stenosis. The mean age was 44.9 years with a sex ratio of 1:1. All patients were treated according to the random protocol "Lesions of the main airway (MA) protocol," which considers the following stenosis variables: stage of development (S), caliber (C), and length (L). We performed 38 Küster operations, 14 Pearson operations, and 2 combined Pearson-Küster-Rethi operations (ROs).

Results: Overall mortality of the series was 1.85%, with a specific morbidity of 27.7%. A total of 96.2% of patients were cured (85.6% of Pearson operation and 100% of Küster operation). We performed 3.7% re-interventions (14.2% of Pearson operation and 0% of Küster operation), and the failure rate was 3.7% (14.4% of Pearson operation and 0% of Küster operation). We had 27.5% who had postoperative complications (28.5% of Pearson operation and 26.3% of Küster operation). The most frequent complications were restenosis (14.2%), granulation tissue (13.1%), edema (10.5%), anastomotic dehiscence (7.1%), and tracheoesophageal fistula (7.1%). In terms of the SCL variables, significant differences were only observed with respect to morbidity between the S4 group and the other cases without tracheoesophageal fistula in the Küster operation group; we found no differences in Pearson operation.

Conclusions: Application of the Main Airway protocol allowed development of a strategy for the surgical treatment of main airway stenosis. This, in turn, enabled a strict selection of cases and meticulous preoperative preparation that, coupled with a highly effective surgical technique, led to excellent outcomes with minimal sequel. The presence of tracheoesophageal fistula could increase the complications.
