Traumatic diaphragmatic rupture: look to see

OBJECTIVE Traumatic diaphragmatic rupture (TDR) is a rare but potentially life threatening clinical entity with a high incidence of associated injuries. In this article, our experience with this challenging diagnosis is presented. METHODS In this study, a total of 68 patients with TDR, were operated in our center between July 1994 and September 2005. Study group was analyzed retrospectively. The etiological factors, management and outcomes were discussed. RESULTS The mean age was 32.9 years with a female to male ratio of 9/59. TDR was right-sided in 16.2% (n=11) and left-sided in 83.8% (n=57). The cause of the rupture was penetrating trauma in 51 (75%), and blunt trauma in 17 (25%). Only three patients (4.4%) had late diagnosis. Associated injuries were seen in 91% (n=62) of the patients. The most common used incision was a laparotomy incision (89.6%). Morbidity and mortality were encountered in 13.1% (n=9) and 16.2% (n=11) patients, respectively. CONCLUSIONS Although rare, diaphragmatic rupture must be suspected in any patient with thoracoabdominal injury. Early diagnosis of TDR is sometimes difficult and depends on a high index of suspicion. Surgical repair is necessary even for small tears. The most common approach is the transabdominal approach, which allows a complete exploration of the abdominal organs for associated injuries. The transthoracic approach might be used in most cases with latent diaphragmatic rupture.

Autologous Blood Patch Pleurodesis in Spontaneous Pneumothorax with Persistent Air Leak

In a prospective study series of 167 patients with tube thoracostomy for spontaneous pneumothorax in 1993-1996, 32 patients (age range 16-79 years, mean age 45.5 years) were treated with autologous blood-patch pleurodesis for persistent air leak. In 27 (84%) of cases the air leak ceased within 72 h after the pleurodesis. The duration of air leak was significantly shorter (p < 0.01) than in simple drainage. Empyema developed in three cases, and two patients with failed pleurodesis required open thoracotomy. Minor complications, mainly fever and pleural effusion, occurred in nine patients. Neither analgesia nor sedation was required during or after pleurodesis. There was no recurrence of pneumothorax during 12-48 months of observation, whereas simple drainage was followed by recurrence in 22 patients. Blood-patch pleurodesis is a simple, effective and painless method in pneumothorax, but carries an increased risk of intrathoracic infection.

Prognostic factors for survival in patients with thymic epithelial tumors.

BACKGROUND Aim of the study was to identify and evaluate the prognostic efficacy of standard clinicopathological factors of thymic epithelial tumors (TETs) for treatment-related outcomes. MATERIALS AND METHODS All patients treated between 1993-2008 at Ege University Faculty of Medicine Departments of Radiation Oncology and Thoracic Surgery were reviewed retrospectively. RESULTS Forty-seven patients with a median age of 51 (range: 24-72) were identified. Complete resection was performed in 23 (51.1%), incomplete resection with microscopic residues in 17 (37.8%), subtotal resection with gross residues in 2 (4.4%) and biopsy in 5 (11.1%) patients. Radiotherapy was administered to 39 (83%) patients. Median follow-up duration was 51 months (range: 3-168 months). Five-year local recurrence-free survival (LRFS), disease-free survival (DFS), and overall survival (OS) rates were 93%, 90% and 85% for thymoma and 80%, 66% and 72% for thymic carcinoma patients, respectively. In multivariate analysis, the extent of resection was the only significant prognostic factor for OS (P = 0.001). CONCLUSIONS The most important prognostic factor for overall survival was the extent of resection. Further studies with larger numbers of patients are required to confirm the prognostic factors and to obtain a better understanding of the biological behavior of TETs.

Ligasure Vessel Sealing System versus Harmonic Scalpel for Sutureless Nonanatomical Pulmonary Resections in a Rabbit Model

Background: The safety and efficacy of the ligasure vessel sealing system (LVSS) and harmonic scalpel (HS) in sutureless nonanatomical lung resections were evaluated. Methods: On twenty adult rabbit lungs, 1 × 1 cm wedge resections were performed under one-lung ventilation with both LVSS and HS. The air tightness and tissue damage caused by these different techniques were measured and compared. Results: No statistically significant differences were found when the air tightness for both devices was compared after resection (p = 0.37). Tissue damage was obtained for LVSS, and the difference was statistically significant (p < 0.001). Discussion: LVSS and HS can both be used for peripheral lung resections without any need of further intervention for securing the air tightness. LVSS was found safer by means of tissue damage when compared with HS in this experimental study.

Postoperative Radiotherapy in the Management of Resected Non–Small-Cell Lung Carcinoma: 10 Years' Experience in a Single Institute

PURPOSE This study reports the long term outcomes of postoperative radiotherapy in patients with resection for non-small-cell lung cancer (NSCLC). METHODS AND MATERIALS A total of 98 patients with resected NSCLC who received postoperative radiotherapy (PORT) between January 1994 and December 2004 were retrospectively analyzed. The most frequently performed surgical procedure was lobectomy (59 patients), followed by pneumonectomy (25), wedge resection (8), and bilobectomy (6). Postoperative radiotherapy was delivered as an adjuvant treatment in 71 patients, after a wedge resection in 8 patients, and after an R1 resection in 19 patients. The PORT was administered using a Co-60 source in 86 patients and 6-MV photons in 12 patients. A Kaplan-Meier estimate of overall survival, locoregional control, and distant metastasis-free survival were calculated. RESULTS Stages included I (n =13), II (n = 50), IIIA (n = 29), and IIIB (n = 6). After a median follow-up of 52 months median survival was 61 months. The 5-year overall survival, locoregional control, and distant metastasis-free survival rates for the whole group were 50%, 78%, and 55% respectively. The RT dose, Karnofsky performance status, age, lateralization of the tumor, and pneumonectomy were independent prognostic factors for OAS; anemia and the number of involved lymph nodes were independent prognostic factors for LC. CONCLUSIONS Doses of PORT of greater than 54 Gy were associated with higher death rate in patients with left-sided tumor, which may indicate a risk of radiation-induced cardiac mortality.

The Effect of Blood Vessel Invasion on Prognosis of Operated Stage I Non-small Cell Lung Cancer Patients

OBJECTIVE A retrospective study was conducted to identify the effect of blood vessel invasion on prognosis in surgically treated stage I non-small cell lung cancer patients. METHODS A total of 71 consecutive patients who had undergone complete resection for stage I primary non-small cell lung cancer (NSCLC) between 1998 and 2007 were evaluated. All pathological specimens were examined for evidence of blood vessel invasion. The follow-up period was 5-118 months. Survival data were analyzed for all patients using the Kaplan-Meier test. RESULTS There were 63 men and 8 women (mean age 59.2, age range 35-86). The most common tumor types were adenocarcinoma (35 patients, 49 %) and squamous cell carcinoma (26 patients, 37 %). Twenty-five patients (35 %) had stage IA disease, and 46 had (65 %) stage IB disease. In 13 cases (18 %) blood vessel invasion was demonstrated, whereas in the remaining 58 cases there was no evidence of vascular invasion. Minimum and maximum follow-up periods were 5 and 118 months respectively, with a mean of 41.76 +/- 27 months (median 33.5 months). Overall disease-free survival was 79.6 +/- 6.4 months: 38.3 +/- 12.0 months for the group with blood vessel invasion and 87.5 +/- 6.7 months for the remaining group. The difference between the two groups was statistically significant ( P < 0.003). Overall survival rate was 86.7 +/- 6.7 months: 44.5 +/- 11.3 months for blood vessel invasion group and 98.2 +/- 6.2 months for the remaining group. The difference between the two groups was statistically significant ( P < 0.001). CONCLUSION Vascular invasion can be an important factor for predicting unfavorable prognosis in stage I NSCLC patients.

Alveolar adenoma: an unusual lung tumor

A 34-year-old woman presented with chest pain and a solitary pulmonary nodule on chest roentgenogram. She was diagnosed with a rare benign lung tumor, alveolar adenoma of the lung, through pathological examination of the surgical specimen resected from the left upper lobe. Clinicians should also keep this entity in mind when making the differential diagnosis of a solitary pulmonary nodule.

Preserving T2 in thoracic sympathicotomy for palmar hyperhidrosis: less tissue trauma, same effectiveness.

BACKGROUND The aim of this study was to compare two different sympathicotomy procedures for primary hyperhidrosis in terms of compensatory sweating, complications, safety and effectiveness. METHODS The data of 78 consecutive patients who underwent bilateral endoscopic thoracic sympathicotomy (156 laterals) for palmar hyperhidrosis between January 2005 and September 2009 were studied retrospectively. The first 29 consecutive patients were treated with a T2-3 sympathicotomy (Group A). After November 2007, all patients (49 patients) were treated with a T3 sympathicotomy alone (Group B). The chest tubes were always removed after checking for pneumothorax with roentgenography. All patients were followed up and evaluated for results, side effects, complications, and satisfaction levels. The differences between the two groups were analyzed. RESULTS The mean age of the 47 (60.2 %) female and 31 (39.8 %) male patients was 25.2 years. Horners syndrome and pneumothorax was not detected in either group. The mean follow-up time was 20.82 months (6-52 months). Effectiveness of the procedure at the time of discharge and at follow-up was 100 % and 97.5 %, respectively. There was no significant difference between groups with regard to any analyzed parameter. CONCLUSION This study demonstrates that preserving the T2 ganglion is safe, and does not compromise the effectiveness of the procedure. Sympathicotomy has the same success rate as sympathectomy, but requires significantly less dissection and results in less tissue trauma.

[A life-saving approach after thoracic trauma: emergency room thoracotomy].

BACKGROUND In this article, the outcomes, indications and methods of emergency department service resuscitative thoracotomy in cardiac and/or respiratory arrest patients after thoracic trauma are discussed. METHODS Between January 2004 and December 2010, nine resuscitative thoracotomies were performed after thoracic trauma in the emergency department of our hospital. The records of the patients were evaluated retrospectively. RESULTS A total of nine patients underwent resuscitative thoracotomy: five stab wounds, two traffic accidents, one fall from height, and one gunshot wound. Anterolateral thoracotomy in supine position was performed in all. Three patients had lung parenchymal laceration, three patients had cardiac laceration, two patients had intercostal vessel injury, and one patient had descending aorta injury. None of the four patients with blunt trauma recovered. Three of five patients with penetrating trauma were discharged after an average of eight days of follow-up, whereas two of them were lost perioperatively. CONCLUSION Emergency room thoracotomy can be performed in thoracic trauma cases who are in shock and have unresponsive hypotension despite large volume fluid and blood replacement and no time for transportation to the operating room. The results are better in penetrating trauma patients than in blunt trauma.

Myasthenia Gravis with Thymoma: Histopathologic Examination and Rate of Complication After Surgery

Aim It is known that thymus and thymoma have a role in the etiopathogenesis of myasthenia gravis (MG). These associations and their effects on the survival have investigated in several studies since 17th century. The incidence of MG in patients with thymoma was reported to be 20-50% in different studies. The aim of this study is to investigate the relationship between thymoma and MG and to evaluate the rates of postoperative complications. Material and Methods The study included 25 patients (13 female and 12 male) and the mean age of patients was 42.3 years (range 24 to 70 years). 11 (44%) of patients had been treated with the diagnosis of MG. Eight (57%) of 14 (56%) patients without the diagnosis of MG had no symptoms and thymoma was detected accidentaly. The common symptom of the other 6 (43%) patients was cough. 9 (36%) patients were staged according to WHO classification. The other patients could not be staged according to WHO classification; because they were operated before the year of 2001. Four of patients were stage B1, 2 were stage B2, 2 were stage B3 and 1 was stage AB. Postoperative complication occured in 4 (16%) patients. Results MG was seen with a higher rate in cortical thymoma when compared with medullary thymoma, in immunohistochemical investigations. MG had been thought as a negative prognostic factor for thymoma but in the last years it had been reported as a positive prognostic factor due to the development of postoperative intensive care conditions, medical therapy and follow up.
