Postmastectomy lymphedema: long-term results following microsurgical lymph node transplantation.

Background and Objectives:Lymphedema complicating breast cancer treatment remains a challenging problem. The purpose of this study was to analyze the long-term results following microsurgical lymph node (LN) transplantation. Methods:Twenty-four female patients with lymphedema for more than 5 years underwent LN transplantation. They were treated by physiotherapy and resistant to it. LNs were harvested in the femoral region, transferred to the axillary region, and transplanted by microsurgical procedures. Long-term results were evaluated according to skin elasticity, decrease, or disappearance of lymphedema assessed by measurements, isotopic lymphangiography, and ability to stop physiotherapy. Results:The postoperative period was uneventful; skin infectious diseases disappeared in all patients. Upper limb perimeter returned to normal in 10 cases, decreased in 12 cases, and remained unchanged in 2 cases. Five of 16 (31%) isotopic lymphoscintigraphies demonstrated activity of the transplanted nodes. Physiotherapy was discontinued in 15 patients (62.5%). Ten patients were considered as cured, important improvement was noted in 12 patients, and only 2 patients were not improved. Conclusion:LN transplantation is a safe procedure permitting good long-term results, disappearance, or a noteworthy improvement, in postmastectomy lymphedema, especially in the early stages of the disease.

Catamenial pneumothorax: retrospective study of surgical treatment

BACKGROUND Catamenial pneumothorax is a rare entity characterized by recurrent accumulation of air in the thoracic space during menstruation. Catamenial pneumothorax is also associated with a high rate of postoperative recurrence. The aim of this study was to discuss the etiology and to determine the optimal surgical treatment of this entity. METHODS From December 1991 to September 2000, 10 patients with catamenial pneumothorax were treated at our institution. Median age at time of operation was 37 years (range, 21 to 44 years). We retrospectively evaluated the pathologic findings, the operation performed, and the results in all patients. The mean follow-up was 55.7 months. RESULTS Pleurodesis alone was performed in 5 patients and an associated diaphragmatic procedure was performed in 5 patients. In 5 patients, no diaphragmatic anomaly was discovered: 3 experienced one or more recurrences and all still suffer from chronic catamenial chest pain. Hormonal therapy temporarily improved outcome for 6 months in 2 patients. On the contrary, in 5 patients surgical pleurodesis was associated with the repair of diaphragmatic defects (simple closure or coverage by a polyglactin mesh): these patients experienced no recurrence (n = 0/5, p = 0.0016) and no subsequent catamenial chest pain. CONCLUSIONS The postoperative outcome is influenced by the diagnosis of diaphragmatic defects with or without endometriosis. Surgical treatment should be accomplished during menstruation for an optimal visualization of pleurodiaphragmatic endometriosis. Because diaphragmatic lesion is frequent and may be occult, we propose the systematic coverage of the diaphragmatic surface by a polyglactin mesh to prevent catamenial pneumothorax recurrence even when the diaphragm appears normal.

Postmastectomy neuropathic pain: results of microsurgical lymph nodes transplantation.

UNLABELLED Postmastectomy chronic pain may be divided into widespread and regional pain. Almost half patients with regional pain, which is more likely related to neuropathic phenomena, do not benefit any pain relief from medication. Our purpose was to report results on pain relief obtained by axillary lymph nodes autotransplantation. METHODS Six patients presented with chronic regional neuropathic pains and upper limb lymphedema after breast cancer surgery and radiation therapy. Despite medication, pain was intolerable and daily activity dramatically reduced. Lymph nodes were harvested in the femoral region, transferred to the axillary region and transplanted by microsurgical procedures. RESULTS Lymphedema resolved in 5 out of 6 patients. Pain was relieved in all, permitting return to work and daily activity; analgesic medication was discontinued. CONCLUSION This procedure proved efficient and may be advocated in case of neuropathic pain when discussing lymphedema management.

Value of cancer antigen 125 for diagnosis of pleural endometriosis in females with recurrent pneumothorax

The thorax is the most frequent extrapelvic location of endometriosis. Thoracic endometriosis is probably responsible for the high rate of recurrent pneumothoraces in females. The goal of the present prospective study was to assess the value of cancer antigen (CA)125 measurement in the detection of endometriosis in order to further enable early and adequate treatment of catamenial pneumothorax. Between January 2004 and March 2006, 31 females (mean age 32 yrs) underwent pneumothorax surgery. The control group comprised 17 males (mean age 27 yrs), who underwent videothoracoscopic pleural abrasion. Serum CA125 was measured around a menstrual period in females and before surgery in males. Videothoracoscopically diagnosed endometriosis occurred in 29% of females. The CA125 concentration was significantly higher in females with endometriosis compared to disease-free females (76.1 versus 16 U·mL−1). The mean value in males was similar to that observed in disease-free females. The frequency of thoracic endometriosis-related pneumothorax corresponds to, on average, a third of females presenting with recurrent pneumothorax. Early detection can be achieved with serum cancer antigen 125 measurement and may be helpful in indicating videothoracoscopic surgery.

Recurrent pleural effusion complicating liver cirrhosis

BACKGROUND Pleural effusion (PE) is a rare complication of advanced liver cirrhosis, which may lead to an operation when uncontrolled. The purpose of this study was to evaluate the modality of the occurrence of pleural effusion and to describe its surgical management. METHODS We studied 21 patients who were referred to the department of thoracic surgery because of massive and recurrent PE caused by liver cirrhosis. The PE was a transudate in 16 patients and an exudate in 5. Talc pleurodesis was attempted in all patients. The patients were divided into two groups. Video assisted thoracoscopy was performed in 13 patients in whom the clinical condition permitted general anesthesia; the pleural cavity was entirely explored before pleurodesis (group 1). Chest tube drainage alone was performed in 8 patients who were unable to undergo general anesthesia; talc pleurodesis was performed through the chest tube in these patients (group 2). RESULTS In group 1 the PE was right-sided in 8 patients, left-sided in 3, and bilateral in 2. Diaphragmatic defects were observed in 2 patients, and a fluid leak oozing from the diaphragm was observed in 1 patient. Ten patients were considered cured and were without recurrence. Two patients underwent late recurrence before dying from their liver cirrhosis. Only 1 patient had an early recurrence that was cured by complementary talc slurry. In group 2 all patients presented with a right PE; of these, 3 patients died from septic shock caused by pleural infection. Three patients underwent early recurrence but were cured after repeat talc slurry. One patient had a midterm recurrence. One patient had an early recurrence treated by intrahepatic porto-systemic shunt with partial improvement. CONCLUSIONS Passage of ascites through diaphragmatic defects appears to be the main cause of PE complicating cirrhosis. Patients may benefit from talc pleurodesis. Video assisted thoracoscopy pleurodesis is the technique of choice with consistent results. Repeated talc injection through the drain may prove useful for patients in poor clinical status.

Strategies and outcomes in pulmonary and extrapulmonary metastases from renal cell cancer

OBJECTIVE Resected renal carcinoma related lung metastases (LM) are associated with higher survival rates, but surgery for extrapulmonary metastases affords good results too. Patients operated on for extrapulmonary metastases before thoracotomy are at high risk of death. The purpose of our analysis was to explore the surgical impact on the outcome of patients with such association. METHODS We reviewed the data of 15 patients operated for LM and extrapulmonary metastases from 1984 to 2005. We studied demographic and clinical characteristics, surgical results and pathological staging of the primary tumour and LM in search of prognostic factors. RESULTS Nephrectomy and metastasectomies were synchronous in only one patient. For the others, mean time interval between nephrectomy and surgery for LM was 74.2 months (range 19-228). Metastases were resected synchronously in two patients and metachronously in 13 of them (mean time interval: 28 months). Five-year survival of this group was 32%, median value of 18 months. The prognosis was better when the resected extrapulmonary metastases were located in the perirenal (pancreas, adrenal gland) or intrathoracic structures (lymph nodes, diaphragm) than in distant visceral organs (brain, bone, thyroid gland). The lymphatic drainage for these structures connects with the thoracic duct in a similar manner as kidneys do. CONCLUSION Surgery for lung and extrapulmonary renal cell cancer-related metastases provides favourable results and is indicated when complete resection can be achieved. The role of the lymphatic system must be explored by further investigations.

Lobectomy for metachronous lung cancer after pneumonectomy

Second primary non-small cell lung cancer (NSCLC) is a well-known disease in patients having undergone successful NSCLC resection. Surgery for patients with cancer in the residual lung after pneumonectomy should not be excluded automatically. However, surgery on a single residual lung is usually done by wedge resection or segmentectomy, whereas lobectomy remains somewhat exceptional. We report the cases of two right upper lobectomy patients, alive and doing well at 5- and 6-year follow-up, with a FEV1 equal to 36% and 35% of predicted value, respectively.
