Impact of routine videothoracoscopy as the first step of the planned resectiona for lung cancer. Experience of 1306 cases

We have analyzed our experience of 1306 patients with NSCLC, submitted from November 1991 to December 2007 to routine videothoracoscopy exploration, as the first step of the planned procedure, in order to evaluate its validity in obtaining precise assessment of tumor extension, verifying thoracoscopic resectability and in decreasing the rate of unnecessary thoracotomies. Thoracoscopy revealed inoperability in 58 patients (4.4%) mostly due to pleural dissemination (2.4%) or mediastinal infiltration (1.7%). Of the remaining 1248 (95.6%), 449 (34.4%) had thoracoscopic resection (230 lobectomies, 6 pneumonectomies, 230 wedge resections), 767 (58.7%) underwent open resection (592 lobectomies, 175 pneumonectomies), and 32 (2.4%) had an exploratory thoracotomy (ET). Among the 32 ETs, thoracoscopy had suspected unresectability in 7 (0.5%), had been incompletely carried out in 4 early cases (0.3%) and had been unfeasible in 21 (1.6%). In our previous series from 1980 to 1991 the E.T. rate had been 11.6%. In the present series, after the introduction of routine thoracoscopy, the E.T. rate is 2.4% and the global rate of patients correctly staged, by thoracoscopy is 73.3%, significantly better than by CT. Video exploration resulted highly reliable in excluding conditions of unresectability with a negative predictive value (NPV) of 0.97. We conclude that preliminary thoracoscopy is useful in obtaining correct staging, reliably evaluates resectability of the lesion and helps in decreasing unnecessary thoracotomies

Routine surgical videothoracoscopy as the first step of the planned resection for lung cancer

Objectives Notwithstanding preoperative staging, a number of procedures still end in an exploratory thoracotomy as a result of unexpected findings. The aim of this work is to evaluate the validity of routine videothoracoscopy, performed as the first step of every planned resection for non–small cell lung cancer, to assess tumor resectability and feasibility of the resection through thoracoscopy. Methods and Results From November 1991 to December 2007, in our department, 1306 patients with non–small cell lung cancer, judged operable at conventional staging, underwent videothoracoscopy before the operation. Thoracoscopy revealed inoperability in 58 (4.4%) patients, mostly owing to pleural dissemination (2.5%) or mediastinal infiltration (1.7%). In the remaining 1248 (95.6%), thoracoscopy did not reveal inoperability. Of these, 449 (34.4%) underwent thoracoscopic resection. The other 799 (61.2%) underwent thoracotomy: 767 underwent resection, but 32 (2.5%) had an exploratory thoracotomy. Thoracoscopy had suggested unresectability in 7 (0.5%) patients, had been incompletely carried out in 4 (0.3%), and was unfeasible in 21 (1.6%) owing to insurmountable technical reasons. In our previous series from 1980 to 1991 the exploratory thoracotomy rate had been 11.6%. In the present series, after the introduction of routine thoracoscopy in the staging process, the exploratory thoracotomy rate was 2.5%. Thoracoscopy was reliable in excluding unresectability (negative predictive value 0.97). The global percentage of correct staging was significantly better (P < .0001) by thoracoscopy (73.3%) than by computed tomography (48.7%). Considering T descriptor, video-assisted thoracic surgery correctly matched with final pathologic staging in 96.2% of patients. Conclusions Routine preliminary videothoracoscopy ensured assessment of tumor resectability and feasibility of the resection through thoracoscopy and limited unnecessary thoracotomies

Management of solitary pulmonary nodule

Objectives: The pulmunary nodule is an important diagnostic and therapeutic problem. Diagnostic certainty is only obtained by histological examination. Mini-invasive surgery allows removal of the nodule with minimal sequelae fot the patient. Methods: From October 1991 to December 2006, 370 resections for a pulmunary nodule were performed at our Department of General Surgery of the University of Milan: 276 wedge resections and 94 lobectomies.Results: Frozen section was performed in all the wedge resections, and in the presence of cancer (77 cases), whenever possible (61 cases), the intervention was converted to lobectomy in the same session. In the other 94 cases, the nodule was removed by lobectomy due to impossibility of performing a wedge resection. Conclusions: Despite the refinement of diagnostic techniques, only exeresis of a pulmonary nodule ensures a definitive diagnosis, thus resolving the problem of benign pathologies and initiating the correct therapy for malignant lesions in the same session

Videothoracoscopic approach to mediastinal disease in Harrisons Online

Excerpt:"Mediastinal diseases encompass a wide spectrum of clinical situations comprising diverse diagnostic procedures. Therapy entails different degrees of technical difficulties, ranging from simple removal of benign lesions to more complex resections of large tumors, or to extremely demanding dissection of firmly adherent lesions invading nearby structures....
