Management of Esophageal Perforation

Abstract Despite recent advances in thoracic surgery, the management of esophageal perforation remains problematical and controversial. Thirty-one patients were treated for an esophageal perforation between 1986 and 1998. The esophageal perforation was iatrogenic in 25 cases, spontaneous in 2, traumatic in 2, and caused by a tumor and tuberculous lymphadenitis in 2 patients. There were 10 cervical, 19 thoracic, and 2 abdominal perforations. The interval from perforation to operation was less than 24 h in 12 patients and more than 24 h in 19 patients. The surgical procedures included a primary repair in 12 patients, a resection in 8, and conservative treatment with minor surgical approaches in 11. The mortality rate was 20% (4/20 patients) in the surgical treatment group and 45.5% (5/11 patients) in the conservative treatment with minor surgery group. The overall mortality was 29% (9/31 patients). The prognosis is thus concluded to depend on the cause and location of the perforation, the presence of underlying esophageal diseases, and the surgical procedure chosen.

Single-stage transthoracic approach for right lung and liver hydatid disease.

OBJECTIVE Human echinococcosis remains a serious health problem for the Mediterranean countries. Synchronous pulmonary and hepatic hydatid disease may occur in 4% to 25% of cases. Our experience on simultaneous surgical treatment of right lung and liver hydatid disease in patients was reviewed. METHODS Between 1990 and 2000, 48 patients (33 female patients and 15 male patients) with synchronous right lung and liver dome hydatid cysts were operated with a 1-stage procedure. RESULTS Six patients had previous surgical treatment of hepatic (n = 2) or pulmonary (n = 4) hydatid cyst. The pulmonary cysts were diagnosed with radiography in 18 patients and thoracic computed tomography scan in 30. The pulmonary cysts of 9 patients were bilateral. Seventy-five pulmonary cysts were seen in radiological examinations. The diagnosis of hepatic cysts was established with ultrasonography in 18 patients and upper abdominal computed tomography in 30. The total number of hepatic cysts was 48. In cases with pulmonary cysts, cystotomy and capitonnage were performed in 32 patients, only cystotomy was done in 14 patients, and wedge resection was performed in 2. Liver cysts were approached to transdiaphragmatically after the lung cysts had been dealt with and were managed with evacuation of the cysts. In the remaining cases, marsupialization (n = 2), pericystectomy (n = 1), and enucleation (n = 1) were performed. Major postoperative complications were hemorrhage (n = 1) and biliocutaneous fistula (n = 1). Hepatic recurrence was seen in 3 patients (6.2%) and pulmonary recurrence in 1 (2.1%). CONCLUSION Transthoracic approach is a useful and a safe surgical management of both pulmonary and upper surface of hepatic hydatid cysts.

Management of Recurrent Malignant Pleural Effusion with Chemical Pleurodesis

PurposeMalignant pleural effusion is a common complication of primary and metastatic pleural malignancies. It is usually managed by drainage and pleurodesis, but there is no consensus as to the best method of pleurodesis. We compared the effectiveness, side effects, and cost of different chemical pleurodesis agents used in patients with malignant pleural effusion.MethodsBetween January 1990 and December 2001, 108 patients with malignant pleural effusion underwent chemical pleurodesis in our department. Thoracoscopy was performed in 64 patients (59%), a minithoracotomy in 18 (17%), tube thoracostomy in 11 (10%), and a small-bore catheter was inserted in 15 (14%). Talc was used in 68 (63%) patients, tetracycline in 26 (24%), and bleomycin in 14 (13%). Talc was instilled by insufflation during surgery after drainage, whereas tetracycline and bleomycin were instilled via tube or catheter for pleural analgesia.ResultsTalc resulted in significantly earlier tube and catheter removal, after an average 4.1 days versus 5.1 days after tetracyline, and 6.3 days after bleomycin (P = 0.026, P = 0.001, respectively). A significantly lower reaccumulation ratio in 90 days was achieved by the talc group, with nine (13.2%) patients, representing an 86.8% success rate, than in the tetracyline and bleomycin groups, with seven (26.7%) and five (35.7%) patients, respectively, representing 73.8% and 64.3% success rates (P = 0.04).ConclusionsTalc resulted in the earliest expansion, minimal drainage, and the earliest tube and catheter removal.

Surgical treatment of peripheral lung cancer adherent to the parietal pleura

OBJECTIVES The objective of this paper is to assess the results of surgical treatment retrospectively in a consecutive series of 85 patients with peripheral non-small cell lung cancer (NSCLC) invading parietal pleura and chest wall. METHODS From 1994 to 1998, of the 572 patients having pulmonary resection for NSCLC, 29 patients with neoplasm involving the parietal pleura (group I) and 56 with that invading the chest wall (group II) underwent resection. RESULTS The operative mortality rate was 3.4% in group I and 1.8% in group II. In groups I and II, pathologic N status was N0 in 20 (69%) cases, N1 in five (17%), N2 in four (13.8%) and 44 (78.6%), seven (12.5%), five (8.9%), respectively. An incomplete resection (R1) was performed in two (6.9%) patients in group I and seven (12.5%) in group II. Postoperative radiotherapy was carried out in 18 patients in group I and 46 in group II. Systemic chemotherapy was also administered in seven patients in group I and eight in group II. There was a significant difference in adjuvant therapy between the groups (P<0.05). Two patients (R1) in group I (7.4%) and 12 patients (seven patients R1+5 R0) in group II (24%) had local recurrence. There was no significant difference in local recurrence between the groups (P=12). Follow-up was completed in 79 cases (28 in group I and 51 in group II). Median survival for groups I and II were 27+/-6 and 16+/-4.6 months, respectively. Five-year survival was longer in group I than in group II (33 vs. 14%), but there was no significant difference (P=13). CONCLUSIONS We found similar survival rates for extrapleural resection in limited parietal pleura invasion and chest wall resection in exceeded-beyond-parietal pleura invasion. The completeness of resection is important in both groups.

Prognostic implications of microscopic proximal bronchial extension in non-small cell lung cancer

BACKGROUND The loss of approximately one third of early stage lung cancer patients undergoing complete resection by the end of 5 years implies the existence of unknown or undetected factors at the time of operation. We investigated the possible correlation between microscopic proximal bronchial extension (MPBE) and survival with clinicopathologic features in patients with non-small cell lung cancer. METHODS The bronchial tree with the tumor was dissected and extracted from the lung parenchyma in a total of 62 surgical specimens with non-small cell lung cancer. The tumor-related bronchus was sectioned into serial blocks at a thickness of 5 mm in the transverse plane. Histologically, cut serial sections were examined for MPBE. RESULTS A total of 15 (24.2%) specimens showed MPBE, whereas 47 (75.8%) specimens showed no evidence of MPBE. The median survival time of MPBE-positive patients was 10.0 months, whereas that of MPBE-negative patients was 42.0 months. The 5-year survival rates of MPBE-positive and MPBE-negative groups were 13.3% and 35.8%, respectively, which was a significant difference (p = 0.0203). Multivariate analysis revealed lymph node status (p = 0.0161), histology (p = 0.0268), and MPBE-positivity (p = 0.0447) as independent prognostic factors. CONCLUSIONS Microscopic proximal bronchial extension has an adverse effect on survival in non-small cell lung cancer.

Giant ancient schwannoma of the posterior mediastinum cytologically misdiagnosed as a malignant tumour. A case report.

Abstract We report a case of a 45-year old woman who was found to have a giant mediastinal tumour with radiological degenerative changes. She underwent thoracotomy to remove the mass, which was eventually diagnosed histolo-gically as an ancient schwannoma, whereas cytological interpretation of the accompanying pleural fluid was malignant. Ancient schwannoma is a rare variant of schwannoma, histologically showing atypical features that may result in erroneous diagnosis of a malignant tumour. Clinical and radiological findings are important aids for further consideration of surgical removal of these potentially resectable tumours.

Female and male differences in the survival of patients undergoing resection for lung cancer.

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.

Intercostal arteriovenous hemangioma

We report a case of a 46-year-old man who presented with a chest wall tumor in the right hemithorax. He underwent thoracotomy to remove the mass, which was found to be an arteriovenous hemangioma arising from the intercostal muscle. Arteriovenous hemangioma is a rare tumor and chest wall is an extremely rare site for this tumor. This tumor should be considered in the differential diagnosis of the chest wall tumors. Complete surgical excision offers the best treatment.

Plevral Ampiyem tedavisinde intraplevral streptokinaz uygulaması

Significant morbidity and mortality result from ineffective evacuation of pleural empyema. Standard treatment forpleural empyema includes; pleural drainage, and the use of antibiotics. This conventional treatment may not beeffective for fibrin deposition and loculated empyema. Intrapleural streptokinase is an effective adjunct in the management of pleural emyema, and an alternative treatment of choice for surgery. In this article, we present two cases, which we performed intrapleural streptokinase with the diagnosis of multiloculated pleuralempyema.
