Curved cutter stapler for the application of bronchial sutures in anatomic pulmonary resections: the clinical experience of 139 cases.

OBJECTIVES: One of the fundamental steps in an anatomical pulmonary resection is the main and lobar bronchus suture. Nowadays, two different types of staplers are on the market: the linear TA stapler for open surgery (Tyco Healthcare Group LP, Norwalk, CT, USA), which is based on a 'guillotine' mechanism, sewing, but not cutting the bronchus, and the endoscopic linear stapler which both cuts and sews. This study aimed to fill the void in the use of an instrument used to staple and cut at the same time in 'open' thoracic surgery, eliminating the need for a scalpel: the curved cutter stapler (Contour Curved Cutter Stapler; Ethicon Endo-Surgery, Inc., Cincinnati, OH, USA). METHODS: Between May 2009 and March 2011, the Contour Curved Stapler (Ethicon) was used for the bronchus in 139 cases of non-small cell lung carcinoma (NSCLC)-29 females and 110 males ranging between 48 and 85 years (average 71.1)-and comprising 115 lobectomies (8 bilobectomies) and 24 pneumonectomies (8 on the right lung, 16 on the left lung). RESULTS: All patients underwent a bronchoscopic check-up 30 days after they were discharged: in all cases, the bronchial stump was clearly within normal limits. No cases of bronchopleural fistulas were observed in the 139 patients. CONCLUSIONS: On the basis of this study, the curved cutter stapler showed to be a satisfactory device for securing the bronchus during an anatomic resection (whether lobar or main), in 'open' thoracic surgery. However, even though there were no cases of fistula, we consider that our data is still too limited to be statistically significant.

[Small bowel metastases from lung cancer]. / Le metastasi del piccolo intestino da neoplasie pleuro-polmonari.

Lung cancer is usually diagnosed at an advanced stage and metastases are present in 50% of patients. Small bowel metastases from lung cancer are rare, being more frequent in patients with melanoma, uterine, ovarian, kidney or gastrointestinal cancer, or osteosarcoma. From November 1998 to August 2003, 740 cases of lung cancer (641 non-small-cell lung cancer and 99 neuroendocrine tumours) were diagnosed. We also observed 64 patients with malignant pleural mesothelioma and performed 23 pleuropneumonectomies. Over the same period we admitted 4 patients (one recurrent) with small bowel metastases, three from lung cancer and one from malignant mesothelioma. The clinical symptoms were bowel occlusion and intestinal bleeding. Radiological techniques such as small bowel enema and CT enteroclysis were used with positive results. In one patient with intestinal bleeding capsular endoscopy revealed a bleeding metastasis. All patients were operated on. Neither mortality nor morbidity were observed. All patients were discharged after a median stay of 10 days. One patient is still alive and disease-free 39 months after the first intestinal surgery for metastases. Intestinal metastases from lung cancer are rare and the diagnosis is often late. In some cases the clinical manifestations of the metastases are observed before those of the primitive tumour. However, in the presence of small bowel occlusion and intestinal bleeding of uncertain origin, clinical history-taking is very important and diagnostic procedures must be performed to exclude a secondary pathology.

Traumatic diaphragmatic rupture: personal experience.

402 thoracoabdominal traumas have been observed since November 1998 and seven of these patients (1.7%) showed a diaphragmatic rupture. Four patients showed a right diaphragm rupture and three a left diaphragm rupture. Road traffic accidents were the main cause of trauma. Early diagnosis was performed in three patients (43%), a delayed diagnosis was made to the other patients (57%): one case was an intraoperative diagnosis (14.2%). Everyone had chest X rays and chest and upper abdomen CT scan. One patient had MRI on a late diagnosis. Thoracotomy was performed in all patients and one case (14.2%) of morbility and one (14.2%) of mortality were observed.
