RESUMO
PURPOSE: In the attempt to understand the reasons for and to find a solution to the high recurrence rate after perineal surgery for complete rectal prolapse, we retrospectively analysed the long-term results of Altemeier's procedure alone, or associated with Trans-Obturator Colonic Suspension (TOCS) in a large series of patients with a median interval of 84 months (range 6-258). METHODS: Medical records of 110 patients undergoing Altemeier with levatorplasty (group 1) and 20 patients submitted to the same procedure associated with TOCS (group 2) for newly diagnosed complete rectal prolapse were reviewed. All patients had been recruited after preoperative clinical examination, SF-36 quality of life, continence score and colonoscopy. RESULTS: Mortality was nil. The overall complication and the recurrence rates were 12.3%, and 15.0% (P= 0.769) and 24.6% and 5.0% (P=0.067) in group 1 and 2, respectively. Twelve patients of group 1 with a recurrence were submitted to a redo-Altemeier, 8 to a redo-Altemeier associated with TOCS, and 6 associated with an anterior coloplasty with a mesh. The only patient of group 2 with a recurrence was submitted to a Hartmann's operation. Preoperative vs postoperative mean (SD) continence score was 15.8 (3.1) and 15.6 (3.3) versus 4.1 (1.8) and 3.9 (1.9) in group 1 and 2, respectively (P < 0.001). All parameters of SF-36 improved after surgery (P<0.01) and no differences between the 2 groups were found CONCLUSIONS: Long-term results confirmed the safety and effectiveness of Altemeier's procedure for the treatment of complete rectal prolapse, with the limit of a non-negligible incidence of anastomotic complications and recurrences. The combination of Altemeier with TOCS showed a positive trend to a reduction of the recurrence rate, not worsening morbidity and outcomes.

OBJECTIVE: The aim of this prospective study was to investigate the feasibility and report the short-term results of a new procedure for treatment of pudendal neuralgia, consisting of transperineal injections of autologous adipose tissue with stem cells along the Alcock's canal. METHODS: Fifteen women with pudendal neuralgia not responsive to 3-months medical therapy were examined clinically, with VAS score, validated SF-36 questionnaire, and pudendal nerve motor terminal latency (PNMTL). These patients were submitted to pudendal nerve lipofilling. Clinical examinations with VAS, SF36, and PNTML were scheduled during 12 months follow-up, with the incidence of pain recurrence (VAS > 5) as primary outcome measure. Appropriate tests were used for statistics. RESULTS: All patients had preoperative increase of pudendal nerve latencies. Twelve patients completed the follow-up protocol. There was no mortality, and no complications. Two patients had no pain improvement and continued to use analgesic drugs. At 12 months VAS significantly improved (3.2 ± 0.6 vs 8.1 ± 0.9, P < 0.001), as well SF36 (75.5 ± 4.1 vs 85.0 ± 4.5 preoperative, P < 0.01), while PNTML showed a nonsignificant trend to a better nerve conduction (2.64 ± 0.04 vs 2.75 ± 0.03 preoperative, P = 0.06). CONCLUSIONS: The new technique seems to be easy, with low risk of complications, and with significant improvement of symptoms in the short period. A larger study with appropriate controls and longer follow-up is now needed to assess its real effectiveness.

OBJECTIVES: Searching for retained bullets has always been crucial in war surgery. Aim of this paper is to briefly outline the history of retained bullet identification methods before X-rays discovery and describe the proliferation of the most significant methods of foreign body localization during WWI. METHODS: Coeval medical journals, reference textbooks, dedicated manuals and documents have been searched and compared in multiple archives and on the internet. RESULTS: Before radiologic era, probing the wound was the only way to detect the bullet and minimize the need of a large surgical incision (anaesthesia was walking its first tentative steps and antisepsis still to be conceived). Nelaton's probe, specifically designed to detect General Garibaldi's retained projectile, gained popularity. Application of electricity provided further rudimental aids to find retained metals. X-rays discovery made bullet detection easy, but exact localization to guide removal was still difficult. Hundreds of imaginative X-Ray methods for localizing bullets and splinters more precisely in the countless complex wounds flourished during the Great War. Axis intersection, geometric reconstruction and anatomical criteria guided localization. Complex procedures and rudimental localizers to simplify calculations, and a number of compasses and magnetic or electric devices to aid surgical removal were developed, and are here outlined. Intermittent radiology assessment or combined radiology and surgery procedures started to play a role. CONCLUSIONS: All these methods and tools are the ancestors of modern navigation systems, ensured by images digitalization and miniaturization technologies. KEY WORDS: Foreign bodies, Mobile Health Units, Radiology, X-Rays, World War I, Wounds and injuries.

OBJECTIVE: The aim of this prospective study was to assess the safety and effectiveness of a new single laparoscopic operation devised to relieve obstructed defecation, gynecologic and urinary symptoms in a large series of female patients with multiorgan pelvic prolapse. METHODS: We submitted 384 female patients to laparoscopic pelvic organ prolapse suspension operation, a new technique based on suspension of the middle pelvic compartment, by using a polypropylene mesh and followed up 368 of them, with defecography performed 12 months after surgery and a standardized protocol. RESULTS: The 368 patients were followed-up for 36.3 (±4.4) months, Recurrence rate was 4.9% for obstructed defecation syndrome and 3.3% for stress urinary incontinence. Complication rate was 2.9%. The mean period of daily activity resumption was 16.3 days (±4.8 days). Anorectal and urogynecologic symptoms and scores significantly improved after the operation (P < 0.001), with no worsening of anal continence. Incidence of postoperative fecal urgency was 0%. Postoperative defecography showed a significant (P < 0.001) improvement of all parameters in 315 patients (82%). Short Form 36 Health Survey score significantly improved after the operation (P < 0.01). An excellent/good overall Satisfaction Index was reported by 78.0% of patients. CONCLUSIONS: In our experience the Laparoscopic-Pelvic Organ Prolapse Suspension seems to be safe and effective as a 1-stage treatment of associated pelvic floor diseases. Randomized studies with an appropriate control group and longer follow-up are now needed to assess the effectiveness of this promising technique.

Medical services in WWI had to face enormous new problems: masses of wounded, most with devastating wounds from artillery splinters, often involving body cavities, and always contaminated. Tetanus, gas gangrene, wound infections were common and often fatal. Abdominal wounds were especially a problem: upon entering the war the commanders of all medical services ordered to avoid surgery, based on dismal experiences of previous wars. Surgical community divided into non-operative and operative treatment supporters. The problem seemed mainly organizational, as the wounded were rescued after many hours and treated by non-specialist doctors, in inadequate frontline settings or evacuated back with further delay of treatment. During initial neutrality, Italian Academics closely followed the debate, with different positions. Many courses and publications on war surgery flourished. Among the interventionists, Baldo Rossi, to provide a setting adequate to major operations close to the frontline, with trained surgeons and adequate instruments, realized for the Milano Red Cross three fully equipped, mobile surgical hospitals mounted on trucks, with an operating cabin-tent, with warming, illumination and sterilizing devices, post-operative tents and a radiological unit. Chiefs of the army approved the project and implemented seven similar units, called army surgical ambulances, each run by a distinguished surgeon. Epic history and challenges of the mobile units at the frontline, brilliant results achieved on war wounds and epidemics are described. After the war they were considered among the most significant novelties of military medical services. Parallels with present scenarios in war and peace are outlined.

PURPOSE: Treatment of rectocele associated with prolapsed hemorrhoids is a debated topic. Transanal stapling achieved good midterm results in patients with symptoms of obstructed defecation, nevertheless a number of severe complications have been reported. The aim of this study was to evaluate the safety and efficacy of a new endorectal manual technique in patients with obstructed defecation due to the combination of muco-hemorrhoidal prolapse and rectocele. METHODS: Patients enrolled after preoperative obstructed defecation syndrome (ODS) score, defecography and anoscopy were submitted to the novel Mucopexy-Recto Anal Lifting (MuRAL) combined with a modified Block procedure, and followed up by independent observers with digital exploration 3 weeks postoperatively, and digital exploration plus anoscopy at 3, 6, and 12 months. Operative time, hospital stay, numerating rating scale (NRS), ODS, satisfaction scores, and recurrence rate were recorded. RESULTS: Mean operative time was 35.7 minutes. Fifty-six patients completed 1-year follow-up: 7.1% had acute urinary retention, NRS score was < 3 from the third postoperative day, mean time of daily activity resumption was 12 days, none had persistent fecal urgency, 82% declared excellent/good satisfaction score, significant improvement of 6- and 12-month ODS score, no recurrence of rectocele, and 7.1% recurrence of prolapsed hemorrhoids were observed. CONCLUSION: MuRAL associated with modified Block technique gave no severe complications and resulted in a safe and effective approach to symptomatic rectocele associated with muco-rectal prolapse. Further randomized studies, larger series, and longer follow-up are needed.
RESUMO
OBJECTIVES: The pulmonary 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 for the patient. METHODS: From October 1991 to December 2006, 370 resections for a pulmonary 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 the 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.

A diabetic patient who at a routine abdominal ultrasounds was found to have a very dilated pancreatic duct. Computed tomography (CT) scan diagnosed a sero-cystic lesion of the pancreatic head. Gastroduodenoscopy discovered a duodenal hyperemic area, which was sampled. Biopsy demonstrated intramucosal vascular emboli from a neuroendocrine carcinoma positive for Chromogranin A and Somatostatin and negative for Gastrin. Cholangio-magnetic resonance imaging revealed that the sero-cystic lesion found at CT, was being mimicked by the enormously dilated pancreatic duct but suggested the possibility of an intraductal or ampullar neoplasm. Blood and urine tests were not helpful and an octreoscan was negative. The patient underwent surgery. Direct exploration confirmed the severe pancreatic duct dilation and a cephalic lesion requiring a pancreatoduodenectomy. Histology confirmed a neuroendocrine tumor infiltrating the duodenum. We conclude that despite modern sophisticated imaging and endoscopic techniques, the evaluation of bilio-pancreatic region can be challenging and can reserve surgical surprises.
RESUMO
BACKGROUND: The observation of a relatively high number of pulmonary aspirations (PA) among gastric band (GB) carriers undergoing a second surgery, prompted us to modify our strategy for GB patients candidate to further operation under general anesthesia. MATERIAL OF STUDY AND RESULTS: In January 2013, following the occurrence of PA at the induction of general anesthesia in 1 GB carrier undergoing a further operation, we reviewed our Data Base between January 2005 and 2013, to explore the rate of pulmonary aspiration in patients GB carriers undergoing a second surgery. Considering the rate (3/172 - 1.7%) too high in comparison with non-GB carriers, we decided to deflate the banding before any further surgery planned under general anesthesia. We then retrospectively reviewed the occurrence of PA after having changed the protocol. Since February 2013, through December 2016, 81 GB carriers underwent a second surgery and not a single episode of PA occurred (0/81). DISCUSSION: The occurrence of PA in patients with GB seems greater than in non-GB patients. Larger series should be examined to assess the incidence of PA among this specific population. Awareness of the increased risk is important to general anesthesiologists and surgeons, considering the increasing number of GB carriers who may be in need of surgery. Our result after adopting the deflation policy, even though not statistically significant, seems highly suggestive. CONCLUSION: We believe that, considering the potentially severe consequences of PA, the gastric band should be deflated before any planned procedure requiring general anesthesia. Further data are needed. KEY WORDS: Adjustable gastric banding, Aspiration Pneumonia, Bariatric surgery, Morbid obesity, Pulmonary Aspiration.

BACKGROUND: Conservative surgery of hemorrhoidal disease is less painful than traditional hemorrhoidectomy, and mucopexy has less risk of serious postoperative complications than stapled hemorrhoidopexy. The aim of this study was to evaluate the safety and effectiveness of a standardized, modified hemorrhoidopexy, named Mucopexy-Recto Anal Lifting (MuRAL) with the HemorPex System (HPS) in patients with symptomatic III and IV degree hemorrhoids. METHODS: Patients were enrolled from May 2013 to Dec 2015 and operated on with the MuRAL technique, based on arterial ligation and mucopexy at 6 locations, using a standardized clockwise/anti-clockwise rotation sequence of the HPS anoscope. Follow-up controls were carried out by independent observers, as follows: a digital exploration 3 weeks after the intervention, digital exploration plus proctoscopy at 3 and 12 months and repeated at a 12 months interval. Patients who did not strictly follow the postoperative controls were excluded from the study. Primary outcome measurement was the recurrence rate. Secondary measurements were: operative time, hospital stay, postoperative pain, postoperative symptoms and satisfaction score. RESULTS: We operated on 126 patients (72 males, mean age 53.9, range 29-83): 87 (69.6%) with III degree and 39 with IV degree hemorrhoids; 13 patients had a MuRAL as a revisional procedure of a previous operation for hemorrhoids. Mean duration of follow-up was 554 days (range 281-1219). Four patients were excluded from the study. One-year recurrence rate was 4.1%. The mean duration of the intervention was 29.5 minutes (range 23-60) and 92 patients (73%) were discharged during the same day of the operation. Pain VAS Score in the first, second and third postoperative day was 3.9, 2.5, and 1.9, respectively. Twenty-two patients (18%), all submitted to spinal anesthesia, had postoperative acute urinary retention. Fecal urgency, observed in 18.8% of patients at the first control, disappeared within one year after the operation. Mean time to return to normal activity was 8 days (range 5 -10). The patient satisfaction scores at one-year follow up were 31.1% excellent, 57.4% good, 7.4% fairly good and 4.1% poor. In patients with III degree hemorrhoids operative time was significantly shorter, postoperative pain better and transient fecal urgency lower than in IV degree patients. In our experience the standardization of MuRAL operation with HPS, turned out to be a safe and effective minimally invasive approach in managing symptomatic III and IV degree hemorrhoids, avoiding the risk of severe complications, with the possibility to perform a redo-MuRAL in the event of recurrence. CONCLUSIONS: In our series up to 88% of the patients reported a good, or excellent one-year satisfaction score. Further comparative randomized studies with longer follow-up period are needed.

A randomized study was carried out to compare the mid-term outcome of transanal rectal resection with the CCS-30 TRANSTAR and two TST36 staplers in patients with obstructed defecation syndrome. After selection, patients were randomly assigned to 2 groups:104 underwent a TRANSTAR operation and 104 a transanal rectal resection with two TST36 staplers. Patients were followed up with clinical examination, and defecography. Cumulative complication rate was significantly higher in TRANSTAR operation (Pâ¯=â¯0.019). All symptoms and defecographic parameters significantly improved (Pâ¯<â¯0.001), without differences. Costs were significantly lower with double TST (Pâ¯=â¯0.035). Recurrence rates were 6.2% in TRANSTAR group and 11.4% with double TST (Pâ¯=â¯0.206). Two circular TST 36 staplers consent to obtain the same clinical and functional results than the CCS-30, with significantly lower complication rate and costs.

Selected primary lung cancers less than 2cm from the carina or invading the tracheo-bronchial angle, formerly considered inoperable, can be amenable to tracheal sleeve pneumonectomy (TSP). Such a delicate technique, can entail remarkable post-operative morbidity and mortality, and only few clinical series are reported. Purpose of this paper is to examine complications and long-term survival of our personal series and those reported in literature. At our academic department from 1983 to December 2004, out of 99 patients with NSCLC less than 2cm from the carina, 35 (35.4%) were deemed inoperable after conventional staging; the remaining 64 underwent surgery. Since 1993 in every patient with lung cancer we perform a thoracoscopic exploration as the first step of the intervention. Unexpected causes of inoperability were found at thoracotomy in nine patients (14.1%) and at thoracoscopy in two other patients. Of the remaining 53 patients, 52 had a right TSP and one a left TSP. Intraoperative mortality was nil. Perioperative mortality was 7.5%. Major complications occurred in 11.3% of the patients. Thirty (56.6) patients are alive and disease-free 23-97 months after surgery; for 18 (33.4%) of these, more than 5 years have elapsed after the operation. TSP is the only concrete option for treating lung cancer originating less than 2 cm from the carina. The review of our experience and of other reported series suggests that, with careful selection of patients and meticulous surgical technique, operative mortality and complications are acceptable. Long-term survival and prognosis are encouraging.

BACKGROUND: This randomized study compared the medium-term results of stapled anopexy (SA) and transanal hemorrhoidal dearterialization with anopexy (THD) in 4 homogeneous groups of patients, 2 with third- and 2 with fourth-degree hemorrhoids. METHODS: Forty patients with third-degree and 30 with fourth-degree hemorrhoids were randomly submitted to SA (N.=20+15) and THD (N.=20+15), respectively. Clinical controls were done every 6 months from 1 to 42 months after the operation, with incidence of recurrent hemorrhoids as primary outcome measure. Operative time, complications, pain, time to return to normal activity, costs, Short Form-36, and overall patient satisfaction were also evaluated. RESULTS: Frequencies of preoperative obstructed defecation symptoms and prolapse recurrence were higher in patients with fourth-degree hemorrhoids, and SA was more effective than THD in reducing the risk of recurrence at 36±6 months follow-up (P=0.049). Operative time, complications, pain, and time of return to normal activity were similar in the 4 groups. Costs were significantly higher for SA in patients with fourth-degree hemorrhoids (P>0.01). A significant improvement of quality of life was observed in all groups, and no significant difference was found in overall patient satisfaction. CONCLUSIONS: Both techniques are safe and effective in the mid-term period. SA is more effective in reducing prolapse and obstructed defecation symptoms in fourth-degree hemorrhoids, with the disadvantage of higher costs. Prolapse size and presence of obstructed defecation symptoms could be predictive criteria for choice of the best surgical technique.

BACKGROUND: Transplanted patients on immunosuppressive treatment have an increased risk of infections or neoplasms. Transplantation candidates with infection or a suspected malignancy are excluded from transplantation. In patients already transplanted, thoracoscopy can resolve complications or treat the pulmonary pathology without compromising the precarious existing reactive equilibrium. These patients require an approach that is as least traumatic as possible. METHODS: From September 1991 to December 2000, of 2068 videothoracoscopic procedures carried out at our hospital, 2 were in patients who had undergone transplantation and 3 in candidates for kidney, liver, and bone marrow transplantation. Starting from our personal experience in videothoracoscopy as a diagnostic and therapeutic approach, the possibilities of the method in the field of transplantation are reported by a review of the literature carried out by consulting the reference systems of the most important data banks. CONCLUSIONS: In our experience, videothoracoscopy had a major impact on the management of candidates for transplant, because it allowed us to rule out or treat conditions that would have determined exclusion from a transplant program. In transplanted patients, videothoracoscopy allows a correct diagnosis and treatment with minimal trauma.

STUDY OBJECTIVES: The aim of this study was to evaluate our personal experience and survival curves after video-assisted thoracic surgery (VATS) lobectomies for stage I lung cancer, in comparison with the results reported in existing literature. DESIGN: Retrospective analysis of our experience and an overview of literature. SETTING: Department of Surgery, San Giuseppe Hospital, University of Milan. PATIENTS: From October 1991 to December 2001, of 257 patients with clinical stage I lung cancer, 193 patients underwent VATS lobectomy, 7 patients were declared inoperable at thoracoscopic exploration, and 57 patients were converted (18 patients for oncologic reasons and 39 patients for technical reasons). RESULTS: We observed no intraoperative mortality and no recurrence. Survival data were analyzed with the Kaplan-Meier method along with a log-rank test for statistical significance. The global survival rates at 3 years and 5 years were 77.7% and 63.64%, respectively. T1N0 patients had a better survival curve at 3 years and 5 years (83.50% and 70.21%, respectively) compared to T2N0 patients (71.13% and 56.12%). Patients < 70 years of age had better 3-year and 5-year survival rates (82.37% and 73.32%, respectively) than those > 70 years of age (57.49% and 37.09%). This difference was statistically significant (p < 0.01). CONCLUSIONS: Our results after the VATS approach match the "best" results reported in literature following conventional surgery. Minimally invasive surgery seems to imply reduced tissue damage and decreased impairment of immunologic function. VATS lobectomy permits radical oncology as accurately as lobectomy by thoracotomy, provided that long-established standards are respected. In spite of technical difficulties, it could therefore become a valid alternative in treating stage I lung cancer.

STUDY OBJECTIVES: The treatment of patients with non-small cell lung cancer (NSCLC) that is invading the chest wall is still debated. We aim to illustrate the improvements in treatment results that have occurred over last decade. DESIGN: Retrospective analysis of our experience and an overview of the literature. SETTING: Department of Surgery, San Giuseppe Hospital, University of Milan. PATIENTS: From January 1970 to December 1999, of 2,738 patients with NSCLC, we operated on 146 patients (5.4%) with chest wall invasion by NSCLC. Superior sulcus tumors and tumors invading the diaphragm or mediastinum were excluded. We reclassified all cases according to the current TNM classification. RESULTS: We registered one postoperative death (0.69%) and five major complications (3.4%). From 1970 to 1979, of 32 patients, 10 underwent an exploratory thoracotomy (ET) and 22 underwent a radical resection (stage IIB disease, 17 patients; stage IIIA disease, 5 patients). The 5-year survival rate was 22.7% (25% for stage IIB disease). From 1980 to 1989, of 67 patients, 11 underwent an ET and 56 underwent a radical resection (stage IIB disease, 34 patients; stage IIIA disease, 12 patients; stage IIIB disease, 5 patients; and stage IV disease, 5 patients). The survival rate following radical resection was 14.1%, ranging between 23.5% for patients with stage IIB disease and 0% (3 years, 14%) for those with stage IIIA disease. From 1990 to 1999, of 47 patients, 2 underwent an ET, 2 underwent an exploratory thoracoscopy, and 43 underwent a radical resection (stage IIB disease, 23 patients; stage IIIA disease, 20 patients). The survival rate was 42.7% (stage IIB disease, 78.5%; stage IIIA disease, 7.2%). CONCLUSIONS: Considering the low morbidity, mortality, and significant improvement in survival during the last decade, we advocate the performance of radical en bloc resection for the treatment of chest wall invasive NSCLC.

AIM: Aim of this study is to evaluate the validity of videothoracoscopic staging and treatment in a twenty-year-long series of 286 VATS lobectomies for Clinical Stage I NSCLC. MATERIAL OF STUDY: We retrospectively reviewed 1549 candidates to resection after conventional staging from November 1991 to December 2013, and routinely submitted to videothoracoscopy immediately before the procedure. Patients deemed operable at videoexploration were resected by thoracoscopy or thoracotomy. Out of 534 VATS resections 286 thoracoscopic lobectomies for clinical stage I cancers were performed with strict indications and standardized technique; more advanced tumours were converted even when thoracoscopically resectable. Impact of preliminary videothoracoscopy and and longterm Kaplan-Meier survival was analyzed. RESULTS AND DISCUSSION: Out of 1549 patients, videothoracoscopy disclosed inoperability in 62 (4 %), mostly for pleural carcinosis (33pts.-2.1%) or mediastinal infiltration (22pts-1.4%). 534 (34.5%) patients had videothoracoscopic resection (286 lobectomies, 7 pneumonectomies, 241 wedge resections), 919 (59.3%) had thoracotomy resection, 34 (2.2%) had an exploratory thoracotomy (ET). Thoracoscopy had an accuracy rate of 72.4%, was reliable in excluding unresectability (NPV 0.95), and decreased the rate of ETs to 2.1%, ,sparing 596 (38.5%) thoracotomies. There was no intraoperative mortality or recurrence. Stage I patients had 83.8% 3-yr survival and 64.3% 5-yr survival. Five-year survival was significantly better (p=0.004) for T1N0 patients (70%) than T2N0 (55%) and for patients younger than 55 (86.4%) or with lesion < 2 cm (80.8%). CONCLUSIONS: Preliminary videothoracoscopy reliably assesses tumor resectability and feasibility of thoracoscopic resection, limiting unnecessary thoracotomies. Videolobectomies are safe and survival is comparable to open lobectomy. KEY WORDS: Lobectomy, Lung cancer, Minimally invasive surgery, Thoracoscopy, VATS.

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.
