          Abstract

          Introduction

          Iatrogenic injuries of the membranous trachea have become increasingly common and may trigger a cascade of immediate life-threatening complications.

          Case presentation

          A case of a 48-year-old man with an iatrogenic membranous tracheal wall rupture after double-lumen intubation during Ivor Lewis esophagogastrectomy is presented. Tracheal injury was successfully managed surgically with the use of bovine pericardial patch and reinforcement with the gastric conduit which was moved toward the posterior wall of the membranous trachea sealing the wall laceration.

          Conclusion

          Our technique was proved to be safe, effective and not technically demanding. Early recognition with prompt surgery is the gold standard of managing such cases, although small tears can be managed conservatively.

          Iatrogenic ruptures of the tracheobronchial tree.

          Iatrogenic tracheobronchial ruptures are seldom but severe complications after intubation or bronchoscopy. Therefore, we evaluated the reasons, the subsequent therapy and the outcome of patients with tracheal rupture, who were admitted to our hospital. In a retrospective study we examined 19 patients (15 women, four men; 43-87 years) treated for acute tracheobronchial lesions. Eleven (58%) patients had a tracheobronchial rupture by single-lumen tube, four (21%) by double-lumen tube and two patients (10%) by tracheal cannula. A total of 47% of whom were carried out under emergency conditions. Two patients had a rupture due to a stiff bronchoscopy. Mean symptoms were mediastinal and subcutaneous emphysema. Two emergency collar incisions had been done. The localization of ruptures was in all cases in the paries membranaceus, length: 1-7 cm (mean: 4.8 cm). The interval between the onset of symptoms and the diagnose differed widely (up to 72 h), nine (47%) diagnoses were made during intubation/bronchoscopy. One patient, with a small tear (1 cm) was treated conservatively with fibrin-glue. The other 18 patients had surgical repair through a thoracotomy. The postoperative mortality was determined with 42%, which was not dependent on the rupture but basically by the underlying diseases requiring intubation. Iatrogenic tracheal rupture is a dangerous complication with potentially high postoperative mortality, mostly influenced by the underlying disease. Early surgical repair must be the preferred treatment.

            Iatrogenic ruptures of the tracheobronchial tree.

            We did a retrospective study in 12 patients with iatrogenic tracheal or tracheobronchial ruptures treated since 1975. Ten female subjects, one male subject, and one child (age range, 8 to 72 years), all of whom had undergone intratracheal intubation, were admitted to the hospital. Four patients had been intubated with a double-lumen catheter (two Carlens type with carinal spur, two Robertshaw without spur), and seven had had "high volume-low pressure" tubes, placed under emergency conditions in three of those seven cases. In one further case, an unsuccessful attempt of percutaneous tracheostomy had been made. The localization of the ruptures (all of them longitudinally in the membranaceous wall; length, 2 to 13 cm; mean, 7 cm) comprised both cervical and intrathoracic trachea in seven, the intrathoracic trachea in three instances, and the left main stem bronchus in two cases. Ten patients had mediastinal and subcutaneous emphysema, seven presented with a pneumothorax, and nine had intratracheal bleeding. The interval until the onset of symptoms and diagnoses differed widely: twice diagnoses were made intraoperatively, during thoracic surgery. The longest interval until diagnosis was 5 days; only then did the patient show subcutaneous emphysema and have retrosternal pain. All patients had surgical repair. Nine recovered without sequelae, and three died of septic multiorgan failure.

              Indications for surgery in tracheobronchial ruptures.

              Ruptures of the tracheobronchial tree present a life-threatening situation. Nevertheless, therapy is still controversial. Though conservative treatment by antibiotics and intubation with the cuff inflated distal to the tear is favored by some authors, surgical repair is unavoidable in many cases. We present a series of 31 patients (mean age 43.6 years, range 8--72 years) with iatrogenous or post-traumatic tracheobronchial ruptures treated since 1975. Fifteen ruptures were longitudinal tears of the trachea, not extending lower than a distance of 3 cm from the bifurcation, 11 involved the bifurcation and/or the main bronchi. The total length of the longitudinal tears ranged from 2 to 12 cm, five were transverse near complete abruptions of the trachea or main bronchi. Involvement of the full thickness of the wall with free view into the pleural space or to the esophageal wall was present in 29 cases. Twenty-nine out of the 31 patients underwent surgical repair and two were treated conservatively. The length and depth of the lesion, the degree of subcutaneous emphysema, pneumothorax and/or pneumomediastinum as well as clinical signs suggesting incipient mediastinitis were considered when making the decision for surgery. Twenty-five out of the 29 patients experienced an uneventful recovery. Four patients died of sepsis unrelated to the tracheobronchial trauma. One of the two patients who underwent conservative therapy also recovered uneventfully. The other one died because of multi-organ failure due to underlying myocardial infarction. Conveniently localized short lacerations, especially if they do not involve the whole thickness of the tracheal wall, can be treated with antibiotics and intubation with the cuff inflated distal to the tear, avoiding high intra-bronchial pressures also after eventual extubation. In all other cases surgical repair is to be preferred.
