Repair of postintubation tracheoesophageal fistula in polytrauma patients.

OBJECTIVE: We present our modest experience in treating tracheoesophageal fistula (TEF) in polytrauma patients where tracheal resection turns to be risky due to the size of the fistula and to the general condition of the patient. MATERIALS AND METHODS: Four polytrauma patients, three male and one female were treated at our department due to postintubation TEF. Confirmation was obtained endoscopically and radiologically. Surgical treatment consisted of identification and dissection of the fistulous tract and closure of the tracheal defect by transposing strap muscles and suturing them to the defect. Finally, the oesophageal defect was closed and a flap of sternocleidomastoid muscle was interposed between oesophagus and trachea. RESULTS: There was no intraoperative mortality. Three of our patients had an excellent result. The one who unfortunately returned to mechanical ventilation due to respiratory insufficiency developed a recurrent fistula. CONCLUSIONS: (1) Repair of postintubation TEF should be delayed until the patient is fully stabilised and weaned from ventilation. (2) Indirect closure of the tracheal defect with strap muscle transposition and sternocleidomastoid muscle interposition between oesophagus and trachea can be lifesaving.

Treatment of post-pneumonic empyema thoracis.

OBJECTIVE: The present study evaluates the management of 65 consecutive patients with post-pneumonic empyema thoracis (PET) treated in our department during the last ten years. MATERIALS: There were 51 male (78.5 %) and 14 female (21.5 %) aged 23 - 82 years. The initial cause of PET was pneumonia (postoperative and posttraumatic empyemas were excluded). In 2 cases, a bronchopleural fistula coexisted. Diagnosis was based on clinical, radiological and pleural fluid culture findings. Pneumonococci and staphylococci were the predominant bacterial isolates in our series. RESULTS: Tube thoracostomy drainage (TS) was performed in all our patients. Forty-nine patients (75.4 %) were successfully treated with TS alone. The other 16 patients were submitted to thoracotomy: lung decortication (n = 14) along with segmentectomy in two cases and the Eloesser procedure, also in two cases. The mortality rate reached 9.2 % (n = 6). Septic shock, multiple organ failure, cardiac insufficiency, and end-stage renal failure were the causes. CONCLUSIONS: 1. Complete drainage and full lung expansion by tube thoracostomy with suction are essential in the management of post-pneumonic empyema thoracis. Surgery should only be carried out right away if these conditions are not achieved. 2. Despite clinical experience and the major strategies and procedures available, the mortality remains high.

Primary traumatic pulmonary pseudocysts: a rare entity.

OBJECTIVE: Pulmonary contusion is the usual manifestation of lung parenchymal injury after blunt chest trauma. With deceleration these parenchymal lacerations can result in cavities known as primary traumatic pulmonary pseudocysts (TPPC). We present our experience in treating this rare entity. MATERIAL: From 1989 trough 1999, 14 young patients, 11 male and three female ranging in age between 13 and 24 years were treated for primary TPPC in our department. Blunt chest injuries resulting from traffic accidents were the causes in all our cases. The main symptoms were pain, hemoptysis and dyspnea not associated with severe hypoxemia. The cavitary lesion was apparent in chest radiographs, but the imaging modality of choice was the computed tomography. RESULTS: Multisystem injury was present in 7 of them. Two of our patients required ICU facilities but none needed mechanical ventilation. Hemopneumothorax was present in two cases, whereas pneumothorax in four drained by tube thoracostomy. The hospital stay ranged between 9 and 23 days. Contraction and complete radiological resolution of the PPC needed a follow up of 6-11 weeks. CONCLUSIONS: (1) Primary traumatic pulmonary pseudocysts are benign lesions secondary to blunt chest trauma needing only conservative treatment unless complications arise, such as hemo- or pneumothorax or infection of the cavitary lesion. (2) Computed tomography is a really sensitive method for early detection of the lesion while plain roentgenograms are sufficient for the follow up.

Bronchobiliary fistulae due to echinococcosis.

OBJECTIVE: A bronchobiliary fistula (BBF) is a rare complication of echinococcosis due to rupture of hydatid cysts located at the upper surface of the liver to the bronchial tree. We present our experience in treating this uncommon and dangerous entity. MATERIAL: During the last 20 years, 21 patients, ten men and 11 women ranging in age from 26 to 83 years with a BBF were treated in our department. They presented dyspnea, biloptysis, cough or fever. Diagnostic imaging studies have been very helpful in identifying the communication and in delineating its location. The disease was limited to the liver in 11 cases, whereas in the rest ten cases, both liver and lung were involved. RESULTS: Right thoracotomy was the approach of choice. Our strategy consisted of adequate evacuation of the intrahepatic cysts, obliteration of the cyst space, freeing the adherent lung, dissection and closure of the BBF. Two deaths occurred due to anaphylactic shock and cardiac insufficiency. Follow up at 7-12 years did not reveal any recurrence. CONCLUSION: Although the incidence of echinococcosis has been decreased, the BBF still remains a serious complication with a high morbidity and mortality. Early diagnosis and management of septic associated complications are essential.

Management of esophageal foreign bodies: a retrospective review of 400 cases.

OBJECTIVE: A retrospective study was conducted in 400 patients with esophageal foreign bodies (EFB) to assess characteristics of EFB and methods of treatment. METHODS: From 1962 through 1998, 400 patients with EFB were treated in our department on an emergency basis. There were 202 men (50%) and 198 women (49.6%) ranging in age from 1.5 to 95 years. The main symptoms patients complained of were difficulty in swallowing and pain. Detailed anamnesis, oropharynx and hypopharynx examination and finally radiological examination were the diagnostic tools. The location of the FB was in the cervical esophagus in 57% of cases, in the thoracic one in 26% and at the cardioesophageal junction in 17%. The most common objects found were bones, morsels, coins and needles. RESULTS: The treatment consisted of rigid esophagoscopy under general anesthesia in 343 (85.7%) of our cases. In 57 cases (14.3%) other means such as flexible esophagoscopy, Fogarty or Foley catheters and bougienage turned to be very useful. Only 12 patients (3%) were led to surgery because either extraction was impossible or perforation was present. No major complications occurred in the surgical group, whereas in the group of rigid esophagoscopy, there was one iatrogenous esophageal perforation that presented with empyema thoracis successfully treated. Finally, there was a case of an aortoesophageal fistula with mortal outcome perioperatively. CONCLUSIONS: (1) Esophagoscopy is a reliable method in the treatment of EFB impaction. (2) Alternative methods such as bougienage, etc., can be used only in selected cases with smooth foreign bodies. (3) Surgical treatment is unavoidable in cases of irretrievable EFB or esophageal perforation.
