RESUMO

BACKGROUND: Any type of radical thymectomy, open or thoracoscopic, always results in a skeletonized left innominate vein (LIV), which is highly expected to form adhesions to the posterior surface of the sternum. Therefore, in case of future sternotomy, the LIV remains highly exposed to trauma. METHODS: We describe a surgical technique that is expected to protect the innominate vein in case of future sternotomy. RESULTS: Our technique is not technically demanding, is easily reproducible, can be applied in both open and thoracoscopic procedures and does not significantly prolong the overall duration or cost of the procedure. CONCLUSIONS: Our alternative is the only protective measure for the left innominate vein that can be applied in the first operation and in our opinion should be a standard part of the procedure.

RESUMO

BACKGROUND Persistent air leak following pulmonary lobectomy can be very difficult to treat and results in prolonged hospitalization. We aimed to evaluate the efficacy of a new method of postoperative air leak management using intrapleurally infused fresh frozen plasma via the chest tube. MATERIAL AND METHODS Between June 2008 and June 2014, we retrospectively reviewed 98 consecutive patients who underwent lobectomy for lung cancer and postoperatively developed persistent air leak treated with intrapleural instillation of fresh frozen plasma. RESULTS The study identified 89 men and 9 women, with a median age of 65.5 years (range 48-77 years), with persistent postoperative air leak. Intrapleural infusion of fresh frozen plasma was successful in stopping air leaks in 90 patients (92%) within 24 hours, and in 96 patients (98%) within 48 hours, following resumption of the procedure. In the remaining 2, air leak ceased at 14 and 19 days. CONCLUSIONS Intrapleural infusion of fresh frozen plasma is a safe, inexpensive, and remarkably effective method for treatment of persistent air leak following lobectomy for lung cancer.

RESUMO

PURPOSE: Post-sternotomy deep sternal wound infection (DSWI) is a severe complication of cardiac surgery. The introduction of omental and muscle flaps has resulted in a significant decrease in morbidity and mortality. In this article, we present the findings for a series of 55 consecutive patients with DSWI treated using an alternative bi-pectoral musculofascial flap technique. METHODS: The patients were stratified into two groups (one-or two-stage intervention). Patients with septic wounds initially underwent debridement and wound treatment, while vacuum therapy was used in a subset of the subjects. All patients were treated with wound debridement and bi-pectoral advancement flap reconstruction. RESULTS: 30-day mortality was 5.4%. Most patients (72%) were treated in two stages, while vacuum therapy was used in 20% of the patients. The mean number of hospitalization days was 8 and 12 for the one- and the two-stage groups, respectively. Reconstruction was successful in all but three patients, each of whom developed recurrent infection. No major morbidity was reported at a mean follow-up of 82 months with excellent functional and aesthetic outcomes. CONCLUSIONS: Pectoralis-major muscle flaps remain relevant in the modern management of post-sternotomy mediastinitis. The addition of an omental flap should be considered in cases in which the lower sternum is involved. Prompt diagnosis and a meticulous surgical technique ensure favorable results for the majority of patients.

RESUMO

We report a recurrent solitary fibrous tumor of the mediastinum that was encircling the right pulmonary artery. The resection of the tumor with the involved right pulmonary artery segment and sequential graft reconstruction of the vessel was facilitated by the use of cardiopulmonary bypass. We review the indications, management, and outcomes of cardiopulmonary bypass for the resection of mediastinal masses.

RESUMO

BACKGROUND/AIM: The treatment of patients with solitary hematogenous metastases from non-small cell lung cancer (NSCLC) remains controversial, although numerous retrospective studies have reported favorable results for patients offered combined surgical therapy. Our aim was to determine the role of surgical resection in the management of NSCLC with solitary extrapulmonary metastases and to investigate for possible prognostic factors. PATIENTS AND METHODS: Between January 2004 and December 2012, 12 patients with NSCLC, from two Institutions, underwent metastasectomy for their solitary metastatic lesion. Sites of metastases included brain (n=3), adrenal gland (n=6), thoracic wall (n=2) and diaphragm (n=1). All patients had undergone pulmonary resections for their primary NSCLC. RESULTS: Median survival for the entire cohort was 24.1 months, whereas 1- and 5-year survival rates were 73% and 39%, respectively. Patients with stage III intrathoracic disease had significantly worse survival than those with lower tumor stage. A tendency for adenocarcinomatous histology to positively affect survival was recognized, although it was proven not to be statistically significant. CONCLUSION: Despite the retrospective nature of our study and the small cohort size, it is emerging that combined surgical resection might offer patients with NSCLC with solitary hematogenous metastases a survival benefit. Limited intrathoracic disease and adenocarcinomatous histology might be associated with better outcomes.

RESUMO

Introduction. Sternal osteomyelitis with or without mediastinal infection is a severe and rare complication of median sternotomy. In this paper, an alternative technique for the reconstruction of sternal defects with the use of bilateral pectoralis major pedicled muscle flaps is presented. Case presentation. A 70-year-old man with the diagnosis of poststernotomy osteomyelitis underwent reconstruction of his sternal defect with the use of bilateral pectoralis major muscle flaps. The patient had an uneventful recovery, and the physical examination revealed a normal range of motion for both upper limbs and sternal stability. Conclusion. The proposed technique incorporates a simple mobilization of the two pectoralis major muscles to be used as flaps to fill the sternal defect without the need for humeral detachment or a second cutaneous incision. Using this technique, a muscular implant is made that seals the dead space, which has no tension due to the presence of a second layer. Postoperative results are excellent, not only regarding infection and functionality but also from an aesthetic point of view.

RESUMO

The extent of mediastinal lymph node assessment during surgery for non-small cell cancer remains controversial. Different techniques are used, ranging from simple visual inspection of the unopened mediastinum to an extended bilateral lymph node dissection. Furthermore, different terms are used to define these techniques. Sampling is the removal of one or more lymph nodes under the guidance of pre-operative findings. Systematic (full) nodal dissection is the removal of all mediastinal tissue containing the lymph nodes systematically within anatomical landmarks. A Medline search was conducted to identify articles in the English language that addressed the role of mediastinal lymph node resection in the treatment of non-small cell lung cancer. Opinions as to the reasons for favoring full lymphatic dissection include complete resection, improved nodal staging and better local control due to resection of undetected micrometastasis. Arguments against routine full lymphatic dissection are increased morbidity, increase in operative time, and lack of evidence of improved survival. For complete resection of non-small cell lung cancer, many authors recommend a systematic nodal dissection as the standard approach during surgery, and suggest that this provides both adequate nodal staging and guarantees complete resection. Whether extending the lymph node dissection influences survival or recurrence rate is still not known. There are valid arguments in favor in terms not only of an improved local control but also of an improved long-term survival. However, the impact of lymph node dissection on long-term survival should be further assessed by large-scale multicenter randomized trials.

RESUMO

Objectives. Recent advances in perioperative management, antibiotics, and surgical materials, including mechanical staplers, have decreased the operative risk of pulmonary resection. However, bronchopleural fistula can still occur in some instances, the occurrence often being lethal. This study investigated whether platelet-rich plasma (PRP) promotes granulation of the bronchial stump after pneumonectomy. Methods. Ten pigs were randomized into two groups: (A) control or non-PRP group (pneumonectomy) and (B) PRP group (pneumonectomy and PRP application). PRP was obtained by spinning down the animal's own blood and collecting the buffy coat containing platelets and white blood cells. Results. Increased platelet concentration triggered the healing process. The percentage of granulation tissue formed at the stumps was significantly higher in the PRP group of animals. This observation was confirmed when statistical analysis using Mann-Whitney U test was performed (P = 0.0268). Conclusions. PRP is easily produced with minimal basic equipment and is useful in accelerating granulation of the bronchial stump, although the timing and optimum number of applications in humans require further study. Autologous PRP is a safe, feasible, and reliable new healing promoter with potential therapeutic effects.

RESUMO

PURPOSE: The incidence of gastrointestinal metastases from lung cancer is higher than previously thought as they have been reported in 2-14% of the cases in autopsy studies. However, clinically significant metastases are rare. Small bowel perforation secondary to metastatic non-small cell lung cancer is a very rare clinical entity. The aim of this study is to describe a case of ileal perforation in a patient with intestinal metastases of a non-small cell lung cancer, along with a review of the literature. METHODS: A 57-year-old male with a history of non-small cell lung cancer was referred to our emergency department with signs and symptoms of acute surgical abdomen. A computed tomography scan demonstrated dilated small bowel loops, liver deposits, and signs of perforation of an intra-abdominal hollow viscus. RESULTS: Emergency exploratory laparotomy revealed diffuse purulent peritonitis and a perforated ileal tumor. A segmental small bowel resection and primary anastomosis were performed. Histological and immunohistochemical findings were consistent with a metastatic non-small cell lung carcinoma. Additional evaluation revealed widespread metastatic disease. Unfortunately, despite adjuvant treatment, the patient died of progressive disease 2 months after surgery. CONCLUSIONS: Small bowel perforation due to metastatic non-small cell lung cancer is a very rare clinical entity. The possibility of small bowel metastases should be kept in mind in patients with lung cancer presenting with an acute abdomen. Intestinal perforation occurs in advanced stages and is usually a sign of widespread disease. Aggressive surgery can provide effective palliation and may improve short-term survival. The prognosis is however dismal.

RESUMO

INTRODUCTION: Although posture distortion is a common problem in elderly patients, spinal deformity caused by a thymoma has not been previously reported. Thymomas are slowly growing tumors that predominantly cause respiratory symptoms. CASE PRESENTATION: We report the case of an 83-year-old woman who was admitted with a giant mediastinal mass that had caused progressive spinal distortion and weight loss to our department. The clinical and laboratory investigations that followed revealed one of the largest thymomas ever reported in the medical literature, presenting as a mass lesion placed at the left hemithorax. She underwent complete surgical excision of the tumor via a median sternotomy. Two years after the operation, she showed significant improvement in her posture, no pulmonary discomfort, and a gain of 20 kg; she remains disease free based on radiographic investigations. CONCLUSIONS: In this case, a chronic asymmetric load on the spine resulted in an abnormal vertebral curvature deformity that presented as kyphosis.

RESUMO

The authors describe a case of a giant retroperitoneal liposarcoma that extended into the thigh along the course of the iliopsoas muscle. The tumor was successfully excised en bloc through an abdominal and a proximal thigh incision. Histopathologic examination revealed a well-differentiated, lipoma-like liposarcoma with clear surgical margins. The patient remains well without any evidence of tumor recurrence 18 months after surgery.

RESUMO

There are few reported cases of clear cell tumor of the lung, a very rare benign mesenchymal neoplasm. We describe a 41-year-old asymptomatic man who presented with a coin lesion in a routine chest roentgenogram that was absent in a roentgenogram performed a year earlier. After a thorough workup, including radionuclide scintigraphy, the diagnosis of cell tumor of the lung was established. Somatostatin receptor positivity was demonstrated, and this clear cell tumor of the lung had a rapid growth rate. Because of these features, the benign nature of such a tumor remains questionable.

RESUMO

INTRODUCTION: Diffuse large B cell lymphoma is the most commonly diagnosed non-Hodgkin's lymphoma, whereas lymphoma is the most common cause of mesenteric masses. We herein present a very rare case of a young male patient with a giant diffuse large B cell lymphoma of the mesentery that was incidentally diagnosed during his admission for a road traffic accident. MATERIALS AND METHODS: At laparotomy, a huge tumor measuring 18 x 14 x 10 cm was found originating from the jejunal mesentery. Despite the giant size of the tumor, the patient was completely asymptomatic. After complete surgical recection with clear margins, he recieved six cycles of CHOP chemotherapy in the pre-rituximab era. RESULTS AND DISCUSSION: He remained disease-free 2 years after surgery, but unfortunately, he relapsed with disseminated disease and died 6 months later. Mesenteric lymphomas may remain asymptomatic until they reach a large size. The presence of a bulky mesenteric mass is a poor prognostic indicator. CONCLUSION: Although chemotherapy is the treatment of choice for diffuse large B cell lymphoma, in some cases radical surgery has a role in establishing a definitive diagnosis.
