OBJECTIVE Morgagni hernia is an uncommon type of diaphragmatic hernias. Numerous approaches have been described and, particularly the significance of laparatomy has been emphasized as an operative technique. We present our experience on patients with Morgagni hernia operated on via transthoracic approach in our department. MATERIALS AND METHODS Between January 1986 and March 2000, 16 patients with Morgagni hernia were operated in our department. Their ages ranged from 16 to 68 years (mean 51.5). Five (31.25%) patients were male, and 11 (68.75%) patients were female. Chest roentgenograms, thorax CT, barium enema roentgenographic studies were used as diagnostic utilities. Right posterolateral thoracotomy was performed in all patients. RESULTS Hernia sac was present in all cases. Exploration revealed omentum in hernia sac in eight patients (50%), colon and omentum in seven patients (44%), only colon in one patient (%6). Postoperative course was uneventful. The mean follow-up was 5.7 years. There was no recurrence or symptoms related to the operation. CONCLUSIONS We advocate transthoracic approach for surgical exposure as it provides wide exposure and easy repair of the hernia sac in Morgagni hernia.

BACKGROUND Bronchiectasis is usually caused by pulmonary infections and bronchial obstruction. It is still a serious problem in developing countries as our country. We reviewed the morbidity and mortality rates and outcome of surgical treatment for bronchiectasis. PATIENTS AND METHODS Between 1990 and 2000, 166 patients (92 female and 74 male patients) underwent pulmonary resection for bronchiectasis. The mean age was 34.1 years (range, 7-70 years). Mean duration of symptoms was 5.7 years. RESULTS Symptoms were copious amount of purulent sputum in 135 patients, expectoration of foul-smelling sputum in 109, hemoptysis in 35 and cough in all patients. The indication for pulmonary resection was failure of medical therapy in 158 patients, massive hemoptysis in five and lung abscess in three. The disease was bilateral in six patients and mainly confined to the lower lobe in 127. One hundred and twenty patients had a lobectomy, 13 had a pneumonectomy, 21 had a segmentectomy and a combination of these approaches in 18. Operative morbidity and mortality were seen in 18 (10.5%) and in three (1.7%) patients, respectively. Follow-up was complete in 148 patients with a mean of 4.2 years. Overall, 111 patients were asymptomatic after surgical treatment, symptoms were improved in 31, and unchanged or worse in six. CONCLUSIONS Surgical treatment of bronchiectasis is more effective in patient with localized disease. It is satisfactory with acceptable ratio of morbidity and mortality.

Pulmonary hydatid cysts remain a significant health problem in endemic regions like Turkey. Here, we present our surgical experience in patients with pulmonary hydatid cysts. Between January 1985 and January 2001, 1118 operations were performed in 1032 patients (528 males, 504 females; mean age 32.7 years; range 1–87 years) with pulmonary hydatid cysts in our department. Posterolateral thoracotomy was performed in 1015 (98.3%), two-stage thoracotomy in 34 (3.3%), and median sternotomy in 17 (1.7%) patients. We preferred conservative surgical procedures. As a surgical procedure, cystotomy and capitonnage was performed in 626 (56%), cystotomy alone in 368 (33%), wedge resection in 81 (7%), enucleation in 29 (3%), and decortication in 11 (1%) patients. None of our patients were treated with anatomic resection. During surgery, 949 patients (92%) had unruptured and 83 patients (8%) had ruptured hydatid cyst. The morbidity ratio was 6.7%. Major complications were wound infection (2.3%), prolonged air leak (1.9%), atelectasis (1.2%), pleural effusion (0.8%), postoperative hemothorax (0.6%), and empyema (0.3%). Two patients (0.2%) died within the first month postoperatively. Mean follow-up was 31.2 months. Recurrence was detected in only 35 patients (3.3%). Treatment of pulmonary hydatid cyst is primarily surgical. Medical treatment is indicated for recurrent and multiple hydatid cysts postoperatively. Cystotomy alone, or cystotomy and capitonnage, as parenchyma-preserving surgery, is preferred. Radical surgery including pneumonectomy, lobectomy, and segmentectomy should be avoided.

Hydatid cysts in the cervical region are extremely rare. We report herein a case with a hydatid cyst that was primarily located in the posterior cervical triangle without any pulmonary or hepatic involvement. A hydatid cyst of the neck should be considered in the differential diagnosis of lesions in the cervical region, in endemic areas, so as to avoid any dangerous complications such as contamination and a fatal anaphylactic reaction.

OBJECTIVE Thymectomy remains as the optimal treatment of choice in patients with myasthenia gravis (MG), however, the selection criteria for surgery remains controversial. METHODS We examined the data charts of patients with MG underwent extended thymectomy. We investigated the possible correlations between the clinicopathologic features and clinical outcomes, and analyzed the data to clarify the effect of prognostic factors on clinical outcome. RESULTS A total of 61 patients with a mean age of 35.8 +/- 12.2 years (range, 13-66 years) were analyzed. The overall improvement/remission and clinical worsening rates were 81.9 and 18.1%, respectively. Ossermann stage (P = 0.011) and presence of mediastinal ectopic thymic tissue (P = 0.007) showed a significant correlation with the clinical outcome. Multivariate analysis confirmed Ossermann stage (P = 0.0158), and presence of mediastinal ectopic thymic tissue (P = 0.0100) as independent predictors on clinical outcome. CONCLUSION Ossermann stage and the presence of mediastinal ectopic thymic tissue are potential predictors on clinical outcome in patients with MG undergoing extended thymectomy.

Background: Lung cancer is the most common neoplasm in Turkey, but there is not enough data on the characteristics of this mortal illness in our country. Objectives and Methods: The Turkish Thoracic Society, Lung and Pleural Malignancies Study Group (TTS-LPMSG) conducted a national retrospective hospital-based study to determine the pattern of lung cancer in Turkey. Results: A total of 11,849 lung cancer patients were studied between 1994 and 1998, 90.4% were male and 9.6% were female. The majority of patients were smokers (77.9%) or ex-smokers (10.8%). The mean age at the time of diagnosis was 58.4 years (20–84) and 56.7% of the patients were aged between 46 and 65 years. The most common histological types were squamous cell (45.4%), small cell (SCLC; 20.5%) and adenocarcinoma (20.2%). The majority of patients with non-small-cell lung cancer were diagnosed with metastatic disease (40.4%). Of the patients with SCLC patients, 37.9% had limited stage disease and 62.7% extensive stage disease at diagnosis. Conclusion: The results of the largest data so far collected in Turkey show that the vast majority of patients with lung cancer are male, squamous cell is the most common histological type, and only a small proportion of patients are diagnosed at an early stage.

Catamenial pneumothorax is a rarely encountered entity characterized by recurrent pneumothorax concurrent with menstruation. Numerous mechanisms have been postulated in the etiology of catamenial pneumothorax and treatment is still controversial. We report a case of a catamenial pneumothorax successfully treated with a Gn-RH analogue supporting the efficacy of this regimen and the endometriosis theory as an underlying cause of the disease.

We report the outcomes of patients who underwent reconstruction with Mersilene mesh–methyl methacrylate (MM–MM) sandwich and polytetrafluoroethylene (PTFE) grafts after a large chest wall resection. Between June 1990 and September 2001, 59 consecutive patients (37 men, 22 women; mean age, 48.1 ± 11.8 years; range 22–74 years) underwent large chest wall resection (greater than 5 cm diameter) and reconstruction with prosthetic material in our department. Twenty-one patients (33%) underwent reconstruction with a PTFE graft (group 2) between 1990 and 1994, and 38 patients (67%) underwent reconstruction with an MM–MM sandwich graft (group 1) between 1994 and 2001. Operative morbidity ratios were 5.2% (2/38) in group 1 and 24% (5/21) in group 2 (p =. 036). The paradoxical respiration ratio was significantly higher (p =. 018) in group 2 (5/21: 24%) than it was in group 1 (1/38: 2.6%). The operative mortality ratio was 4.5% (1/21) in group 2 and 0% in group 1. Mean hospital stay was 10.6 days (range 5–21 days) in group 1 and 13.3 days (range 7–36 days) in group 2 (p =. 015). The MM–MM graft is inexpensive and easy to apply, provides better cosmetic options, and offers minimal morbidity. We therefore recommend that the MM–MM sandwich graft be used rather than the PTFE graft for large defects of the anterolateral chest wall and sternum where successful prevention of paradoxical respiration is required.

Polands syndrome is a rarely encountered congenital deficiency involving chest wall and breast deformity associated with hand anomalies. Chest wall reconstruction is necessary if the bony thorax is involved. We present the use of a homologous preserved costal cartilage for reconstruction of the chest wall in an infant with Polands syndrome, the use of which provided optimal chest wall stability with a favourable outcome.

Abstract Objective: In recent years much attention has been focused on the rapidly increasing incidence of primary lung cancer in women. The aim of this study was to determine gender differences in patients treated surgically for lung cancer. Methods: We performed a retrospective review of patients who had lung resection for primary lung cancer from January 1994 to December 1998. Results: There were 530 men and 42 women. Women were younger than men (55.6 ± 10 versus 57 ± 9.9). The difference was not statistically significant (p = 0.9). The mean cigarette consumption was greater in men than in women (p < 0.001). We observed a higher operative morbidity and mortality rate in men compared to women (p < 0.05). Men had more squamous cell carcinoma (61.7%). In female patients, squamous cell cancer and adenocarcinoma were found with almost the same incidence (35.7% versus 33.3%). There was a significant difference in the distribution of cell types (p < 0.001). Pathologic stages for women were; I = 38.2%, II = 21.4%, IIIa = 21.4%, IIIb = 9.5%, IV = 9.5% and for men; I = 40.4%, II = 26.6%, IIIa = 24%, IIIb = 6%, IV = 3%. There was no significant difference in the stage distribution between genders (p = 0.2). Median survival for female and male patients were 38 ± 9.2 and 35 ± 3.2 months. Female patients’ survival was longer than male patients but the difference was not statistically significant (p > 0.05). Conclusions: This study emphasizes sex differences in cigarette consumption, operative mortality and the distribution of cell types of patients with primary lung cancer. These initial results should strongly encourage additional studies in different countries on the interaction between sex and lung cancer characteristics to improve clarity.
