Non-invasive diagnosis in a case of bronchopulmonary sequestration and proposal of diagnostic algorithm.

The case of a 43-year-old woman with intralobar pulmonary sequestration, Pryce type one, is presented. The medical history was characterised by recurrent bronchopneumonia, productive cough with purulent sputum and hemoptysis in the last three years. Diagnosis was made by CT angiography: multiplanar, maximum intensity projection and volume rendering reconstructions were visualised. A volume reduction of middle and lower lobe with multiple cyst-like bronchiectasis was detected and no evident relationship with tracheobronchial tree was pointed out. Reconstructions aimed at evaluating bronchial structures demonstrated no patency of middle and lower lobar bronchi. The study carried out after contrast medium infusion in arterial phase showed a vascular disorder characterised by an accessory arterial branch arising from the upper portion of thoracic aorta which, after moving caudally to pulmonary hilus with a tortuous course, supplied the atelectatic parenchyma. No anomalous venous drainage was detected. The patient underwent surgery with resection of two pulmonary lobes. CT compares favourably with other alternative imaging technique for pulmonary sequestration as multiplanar reconstructions allow not only the detection of supplying vessel, but also the accurate description of heterogeneous characteristics of the mass and adjacent structures. Finally an imaging-based diagnostic algorhithm is proposed.

A rare case of pedunculated bronchial hemangioma.

We describe a rare case of pedunculated endobronchial hemangioma observed in a 60-years-old patient complaining of chronic productive cough and accessional dyspnea which had been progressively worsening over 20 years. The lesion was first noticed at fiberoptic bronchoscopy; then computed tomography scan was performed and integrated with tridimensional reconstruction techniques. Pathology showed the picture of a vascular neoplasm, compatible with capillary hemangioma. The lesion was submitted to laser-assisted endoscopic removal in order to relieve the obstruction, leading to remission of symptoms.

Adrenal masses in neoplastic patients: the role of laparoscopic procedure.

BACKGROUND: The incidence of complications resulting from fine-needle biopsy of adrenal masses in patients already treated by radical procedures for primitive neoplasms of the lungs and kidneys substantiates our opinion concerning laparoscopy as both a diagnostic and therapeutic procedure. METHODS: We performed 70 laparoscopic adrenalectomies from April 1995 to December 1999. In five patients, the adrenal mass appeared at follow-up evaluation in patients submitted to surgery for a spinocellular lung cancer. One patient underwent surgery for renal adenocarcinoma. In two patients, the adrenal mass was present already at the time primitive lung tumor was diagnosed, so adrenalectomy was performed at the first lung surgery in one patient and 2 weeks before lung surgery in the other patient. All the patients were placed in a lateral position for a transperitoneal approach. Right adrenal masses were present in seven patients, whereas one patient had an adrenal mass in a left location. RESULTS: No laparotomy was required. The average surgical time was 160 min. (range, 115-120 min). No morbility or mortality occurred, and the average hospital stay was 4 days (range, 3-11 days). All the patients had a complete removal of their masses, which averaged 4.5 cm (range, 2.5-6 cm) in size. Histology confirmed the metastatic origin of the mass in five of seven patients with primary lung cancer, and in one patient with previous kidney cancer. At this writing, three patients were disease free and still alive respectively at 3, 5, and 18 months. Three patients died of brain metastases respectively at 16, 36, and 36 months. An adenoma was proved in the other two cases. CONCLUSIONS: Laparoscopic adrenalectomy allows us to propose a much more aggressive approach to adrenal masses demonstrated at follow-up evaluation or in patients with primary lung or kidney cancer and no masses at other locations. Nevertheless a much larger study is required for definitive conclusions on a survival rate. We believe that a mini-invasive procedure such as laparoscopy may allow us to replace a rational surgical approach with a more certain pathologic diagnosis.

[Death conference: hindsight in heart surgery]. / Death conference: il "senno di poi" in cardiochirurgia.

We report eight cases of death or decerebration occurred during major cardiothoracic surgery. The technical aspects that contributed to the failure are analyzed on the basis of the Italian Criminal Code (art. 43). When this type of event occurs, a case review frequently identifies failure to take action or imprudent behavior. The informed consent regulation currently in force may be helpful in identifying and following the most prudent conduct for the patient. The "death conference" should be a formalized and binding instrument for hospital accreditation.

[Surgical staging of pulmonary carcinoma. Probability of error]. / Stadiazione chirurgica del carcinoma polmonare. Probabilità di errore.

234 patients with lung cancer and operated in Thoracic and Cardiovascular Surgery Department of Careggi Hospital in Florence have been evaluated in order to examine surgical staging accuracy in comparison with pathological staging. There is a statistically significative difference between surgical and pathological staging as a datum point. Surgeon is inclined to over-estimate the lymph-nodes involvement and the primitive tumor extension. It is important to bear in mind this bent whenever decisions of surgical strategy have to be taken.

[Features and evolution of postoperative pain in patients undergoing thoracotomy]. / Caratteristiche ed evoluzione del dolore postoperatorio in pazienti sottoposti a toracotomia.

We examined in this perspective study 30 patients (15 males and 15 females) who undergone classic thoracotomy for lung or mediastinal diseases, without postoperative complications. Intensity and different qualitative components of postoperative pain have been evaluated in the 1st, 3rd, 5th, the day after last pleural drainage removal and 2 months after the operation. All patients answered a schedule adherent to Questionario Italiano del Dolore (QUID). Pain became less intense chiefly with drainage removal with the same time trend for both sex (parallel curves). Pain is probably stronger in women. From a qualitative point of view, the sensorial component is the same in both sexes. Affective and evaluative component is greater in women: in other words, women realize more than men the painful stimulus and are more troubled. A computerized analysis of answers to a questionnaire like QUID or, better, its evolution, may be helpful for a more effective pharmacological choice between pure analgesics, sedative analgesics and ataractic drugs.

["N2" carcinoma of the lung. Therapeutic considerations]. / Carcinoma del polmone "N2". Considerazioni terapeutiche.

The follow-up of 240 N2 lung cancer cases operated in Thoracic and Cardiovascular Surgery Department of Florence is examined. The analysis is performed in compliance with global survival, "T", histology, therapeutic choices. Global survival is 81% after 6 months, 60% after 1 year, 37% after 2 years, 26% after 3 years, 23% after 4 years, 23% after 5 years. Significative difference on survival does not exist between principal histologic types (squamous, adenocarcinoma, adenosquamous). Raising the "T" survival decreases, but only for adenocarcinoma. Different therapeutic options (only surgery, surgery+radiotherapy, surgery+chemotherapy, surgery+radio and chemotherapy) do not influence the survival in a way statistically significative. From the literature, any certainty about radiotherapy and chemotherapy associated to surgery for N2 lung cancer treatment does not exist at the moment. Thus radical surgery is essential.

[Reliability of computerized tomography in the definition of the "N" parameter in the preoperative evaluation of primary bronchopulmonary tumors]. / Affidabilità della tomografia computerizzata nella definizione del parametro "N" nella valutazione preoperatoria del tumore primitivo broncopolmonare.

In order to evaluate the reliability of thoraco-mediastinal CT in the preoperative evaluation of primary lung cancer, regarding "N" (lymph nodes) parameter, we compared CT data with those obtained at histopathology of mediastinal lymph nodes. We re-examined 130 patients who had undergone lobectomy or pneumonectomy combined with mediastinal node dissection. CT criterion of neoplastic nodal involvement is morphological, based on size of the node as related to its location. CT is very sensitive in evaluating both normal and pathological nodes but not likewise specific; in fact, it does not allow differential diagnosis between neoplastic and phlogistic causes. This limitation must be kept in mind in the preoperative evaluation of the "N" parameter. Moreover, CT findings of mediastinal involvement on the opposite side (N3) must be confirmed with mediastinoscopy or CT-guided biopsy before ruling radical surgery out.
