Conservative manage- ment, including repeated thoracentesis or pleurodesis, seems to be suitable to most cases. Herein, we present a case of efficacious pleurodesis by intrapleural injection of Sapylin, a streptococcus preparation, for the treatment of chylothorax. A 52-year-old non-smoking female farmer was diagnosed as idiopathic chylothorax after we ruled out possible causes including chest trauma, lymphoma, lung cancer, filariasis, tuberculosis, and etc. Two-time intra-thoracic injection of 3 Klinische Einheit (KE) Sapylin achieved rapid and effective control of chylothorax with no severe side effects. Sapylin may facilitate pleurodesis by producing a strong inflammatory response.展开更多

METHODS From July 1997 through December 2003, a total of 1,546 patients underwent pulmonary resection （at least Iobectomy） and systematic mediastinal lymph node dissection for lung cancer in our division. Sixteen patients had a postoperative chylothorax complication. All of these patients in this study were conservatively treated （closed drainage） with complete oral intake cessation and total parenteral nutrition. RESULTS All patients had their condition cured with conservative treatment. The duration of the treatment was 6-21 days. The patients were given normal diet for a mean of 9.8 days after chylothorax diagnosis. CONCLUSION If the correct treatment strategy is selected, most cases of chylothorax after pulmonary resection with systematic mediastinal lymph node dissection can be cured with a conservative strategy.展开更多

Management strategies for chylothorax include cessation of enteral feedings, repeated aspiration, chest drainage, and total parenteral nutrition. It is important to determine which is the better plan for treatment of chylothorax after repair of CDH. The authors report successful management by use of the MCT diet for a neonate with chylothorax after repair of CDH. Case: A male infant weighing 3.0 kg was delivered by cesarean section at 38 weeks of gestation and intubated immediately after birth. Prenatal ultrasonography had disclosed left-sided posterolateral diaphragmatic hernia. After stabilization, surgery was performed via a left-sided transverse supra-abdominal incision. The unfixed colon, small bowel, stomach, and spleen were reduced from the chest with little difficulty. A hernia sac was not present and the left-sided posterolateral diaphragm showed a defect 3.5 cm × 2.0 cm in width. The child was fed via a nasogastric tube starting on postoperative day 4 and dyspnea disappeared. Plain chest X-ray on postoperative day 7 showed left pleural radioopacity. A specimen of the chest drainage examined on postoperative day 10 was typical of lymph, with a triglyceride level of 328 mg/dl. The chest drainage was dark yellowish, and a medium-chain triglyceride formula was used until postoperative day 30, by which time the effusion has disappeared. Discussion: Chylothorax after repair of CDH may be a transient disorder that will resolve after a period of diminished flow through the thoracic lymphatics.展开更多

The reported incidence is 1 in 24,000 births. Medical treatment using octreotide as well as chemical and surgical pleurodesis has been reported, but also few reports on the successful use of Sildenafil exists. We herein report a case of congenital chylothorax referred to our Hospital at 7 days-old. Sildenafil was introduced on day 6 post intubation. Before the introduction of sildenafil, the peak total daily drainage was 106 ml/kg/day (340 mls/day), and after sildenafil was introduced, the total daily drainage dropped progressively to 10 ml/kg/day by day 11 post intubation. This case report highlights the successful use of oral Sildenafil for treatment of congenital chylothorax and also peculiarities of management related to a resource- constrained developing country setting in Africa.展开更多

This condition developed secondarily to minor neck injury which resulted in left side cervical swelling. First treatment was conservative. Surgical intervention was nevertheless necessary to remove a cervical cyst contiguous with the thoracic duct.展开更多

A 77-year-old woman developed traumatic chylothorax and underwent lymphoscintigraphy with radiolabeled albumin to identify the site of lymph leakage. Dynamic imaging demonstrated appearance of focal activity presumably in the upper mediastinum, followed by spread to the left hemithorax. Subsequently, SPECT/CT showed that the leakage site was located in the left side of the upper mediastinum, and this location was confirmed during video-assisted thoracoscopic surgery. Dynamic imaging demonstrated the site of first appearance of abnormal activity, and SPECT/CT enabled detailed localization of the abnormal activity with anatomic correlation. The combination of dynamic imaging with SPECT/CT appears to be recommendable for lymphoscintigraphic assessment of chylothorax.展开更多

It occurs when the thoracic duct or its lymphatic tributaries become blocked or perforated or divided resulting in a chylous pleural effusion. Loss of chyle leads to nutritional deficiencies, dehydration, ionic perturbation and lymphocytes leaks thus increasing the vulnerability for infections and respiratory dysfunction. It is a life-threatening complication increasing the postoperative hospital stay. Management of chylothorax is firstly medical which leads to the cessation of leaks in most of the cases. Surgical treatment by thoracic duct ligation is sometimes necessary after failure of medical treatment. The appropriate time for surgical treatment is a subject of controversy. Methods: Reviewing a series of patients treated between 2000 to 2010 in a single center with the same protocol management, the aim of the study was to identify early clinical variables allowing early surgical treatment in postoperative chylothorax. Results: Thirty-two patients were identified in the study period. There were 21 males (65.6%) and 11 females (34.4%) with a mean age of 55.7 years (range from 9 to 79 years) (Table 1). Twenty-two patients (68.75%) had chylothorax after a surgical intervention, seven patients (21.8%) had chylothorax due to medical causes and three patients (9.3%) after chest trauma. Thirty-eight percent of patients treated conservatively were after lung cancer resection and 35% of patients treated surgically where after esophageal resection. Chylothorax was stopped in 33% of patients after lymphangiography. Cumulative leak per day was 1007 ml/day for operated patients and 397 ml/day for patient treated conservatively. Esophageal resection surgery and the amount of fluid leak were the two factors founded to be associated for the decision of an earlier surgical treatment. Conclusion: Chylothorax arising after esophageal resection with a flow rate of leak of more than 500 ml/day should be proposed to an earlier surgical treatment. Lymphangiography remains a key stone assessment with a double aim diagnostic and therapeutic in chyle leakage.展开更多

The objective of this study was to report a case of idiopathic congenital chylothorax treated with povidone iodine effectively without side effects after failure of conservative treatment by chest drainage. Case presentation: A term female Newborn was admitted in the neonatal intensive care unit at 16 days of life, for respiratory distress. The Clinical examination objectified a Sliverman score of 3/10 with a pleural effusion syndrome. The chest radiography confirmed the pleural effusion and the analysis of the pleural fluid after aspiration confirmed the chylothorax, with a protein rate of 35 g/l, Triglycerids 37 mg/L, and Leukocytes count was 1140/ml with 90% lymphocytes. A chest drainage was performed on the seventh day but followed by the recurrence of the effusion. The use of 5 ml of 4% povidone iodine in the pleural space as a chemical pleurodesis was performed. The clinical and radiological evolution was favorable after 24 hours without relapse or side effects such as allergic reaction or worsening of the respiratory condition. Thoracic ultrasound was performed after 15 days, having objectified minimal right side effusion measuring 5 mm maximum thickness. Conclusion: Chemical pleurodesis by the polyvidone iodine in the chylothorax appears to be affordable and effective, and needs to be more considerate in the conservative treatment of congenital chylothorax.展开更多

文摘Chylothorax is an uncommon disease where fatty fluid accumulates within the chest cavity. Conservative manage- ment, including repeated thoracentesis or pleurodesis, seems to be suitable to most cases. Herein, we present a case of efficacious pleurodesis by intrapleural injection of Sapylin, a streptococcus preparation, for the treatment of chylothorax. A 52-year-old non-smoking female farmer was diagnosed as idiopathic chylothorax after we ruled out possible causes including chest trauma, lymphoma, lung cancer, filariasis, tuberculosis, and etc. Two-time intra-thoracic injection of 3 Klinische Einheit (KE) Sapylin achieved rapid and effective control of chylothorax with no severe side effects. Sapylin may facilitate pleurodesis by producing a strong inflammatory response.

文摘BACKGROUND Postoperative chylothorax is usually regarded as a complication associated with cardiothoracic surgery;however,it is one of the rare complications in orthopedic surgery.This case report describes a female patient who developed chylothorax after a successful L4-S1 transforaminal lumbar interbody fusion surgery.The etiology,diagnosis,and treatment were analyzed and discussed.CASE SUMMARY A 50-year-old woman was admitted with repeated back and leg pain.She was diagnosed with L4 degenerative spondylolisthesis,L4/L5 and L5/S1 intervertebral disc herniation and L5 instability,and underwent successful posterior L4-S1 instrumentation and fusion surgery.Unfortunately,thoracic effusion was identified 2 d after operation.The thoracic effusion was finally confirmed to be chylous based on twice positive chyle qualitative tests.The patient was discharged after 12-d persisting drainage,3-d total parenteral nutrition and fasting,and other supportive treatments.No recurring symptoms were observed within 12 mo follow-up.CONCLUSION Differential diagnosis is crucial for unusual thoracic effusion.Comprehensive diagnosis and treatment of chylothorax are necessary.Thorough intraoperative protection to relieve high thoracic pressure caused by the prone position is important.
文摘OBJECTIVE To review the experience of iatrogenic chylothorax after pulmonary resections for lung cancer and to evaluate our treatment strategy. METHODS From July 1997 through December 2003, a total of 1,546 patients underwent pulmonary resection （at least Iobectomy） and systematic mediastinal lymph node dissection for lung cancer in our division. Sixteen patients had a postoperative chylothorax complication. All of these patients in this study were conservatively treated （closed drainage） with complete oral intake cessation and total parenteral nutrition. RESULTS All patients had their condition cured with conservative treatment. The duration of the treatment was 6-21 days. The patients were given normal diet for a mean of 9.8 days after chylothorax diagnosis. CONCLUSION If the correct treatment strategy is selected, most cases of chylothorax after pulmonary resection with systematic mediastinal lymph node dissection can be cured with a conservative strategy.

文摘Chylothorax is a rare cause of pleural effusion in children, and it is usually difficult to identify the location of chyle leakage due to the small size of the thoracic duct in children. Herein we report an infant case with chylothorax whose leakage of the thoracic duct was successfully located by magnetic resonance lymphangiography (MRL) using pre-contrast MR cholangiopancreatography (MRCP) and gadodiamideenhanced spectral presaturation inversion recovery (SPIR) T1-weighted imaging, which demonstrate the imaging method is easy and effective for detecting the focal disruption of the thoracic duct in children with chylothorax and younger than 8 months old.
文摘Tension chylothorax following blunt thoracic trauma is an extremely rare condition.Here we report such a case and review its management.A 31-year-old man was involved in a road traffic collision.The car rolled over and the patient was ejected from the vehicle.On arrival at the Emergency Department the patient was conscious and haemodynamically stable.Clinical examination of the chest and abdomen was normal.The patient had sustained fractures of the sixth cervical vertebra and the tenth thoracic vertebra,left pleural effusion,haematoma around the descending aorta and fracture of the right clavicle.The left pleural effusion continued to increase in size and caused displacement of the trachea and mediastinum to the opposite side.An intercostal chest tube was inserted on the left side on the second day.It drained 1500 mL of milky,bloodstained fluid.We confirmed the diagnosis of chylothorax by a histopathological examination of a cell block prepared from the left pleural effusion using Oil red O stain.The patient was managed conservatively with chest tube drainage and fat free diet.The chylothorax completely resolved on the eighth day after the injury.The patient was discharged home on day 16.

文摘BACKGROUND Primary membranous nephrotic syndrome with chylothorax as the first manifestation is an unusual condition.To date,only a few cases have been reported in clinical practice.CASE SUMMARY The clinical data of a 48-year-old man with primary nephrotic syndrome combined with chylothorax admitted to the Department of Respiratory and Critical Care Medicine of Shaanxi Provincial People's Hospital were retrospec-tively analysed.The patient was admitted to the hospital for 12 d due to shortness of breath.Imaging showed pleural effusion,laboratory tests confirmed true chylothorax,and renal biopsy revealed membranous nephropathy.After primary disease treatment and early active symptom treatment,the prognosis of the patient was good.This case suggests that chylothorax is a rare complication of primary membranous nephrotic syndrome in adults,and early lymphan-giography and renal biopsy can assist in the diagnosis when there are no contrain-dications.CONCLUSION Primary membranous nephrotic syndrome combined with chylothorax is rare in clinical practice.We report a relevant case to provide case information for clinicians and to improve diagnosis and treatment.
文摘Aim: Chylothorax is a recognized complication after surgery for congenital diaphragmatic hernia (CDH) in a neonate. Management strategies for chylothorax include cessation of enteral feedings, repeated aspiration, chest drainage, and total parenteral nutrition. It is important to determine which is the better plan for treatment of chylothorax after repair of CDH. The authors report successful management by use of the MCT diet for a neonate with chylothorax after repair of CDH. Case: A male infant weighing 3.0 kg was delivered by cesarean section at 38 weeks of gestation and intubated immediately after birth. Prenatal ultrasonography had disclosed left-sided posterolateral diaphragmatic hernia. After stabilization, surgery was performed via a left-sided transverse supra-abdominal incision. The unfixed colon, small bowel, stomach, and spleen were reduced from the chest with little difficulty. A hernia sac was not present and the left-sided posterolateral diaphragm showed a defect 3.5 cm × 2.0 cm in width. The child was fed via a nasogastric tube starting on postoperative day 4 and dyspnea disappeared. Plain chest X-ray on postoperative day 7 showed left pleural radioopacity. A specimen of the chest drainage examined on postoperative day 10 was typical of lymph, with a triglyceride level of 328 mg/dl. The chest drainage was dark yellowish, and a medium-chain triglyceride formula was used until postoperative day 30, by which time the effusion has disappeared. Discussion: Chylothorax after repair of CDH may be a transient disorder that will resolve after a period of diminished flow through the thoracic lymphatics.
文摘A 58 years old male patient underwent esophagectomy for esophageal cancer.Refractory chylothorax happened after operation in spite of different treatment including conservation therapy and thoracic duct ligation.He was enterally administrated 250 mL 30% intralipid before operation.Exploration showed there was a milky leakage from the soft tissue near the anastomotic stoma behind aortic arch where is difficult to handle.We gently mobilized the aorta in the front of the ninth spine and bundled it with its adjacent tissue including azygos vein and thoracic duct with a dacron patch.The leakage ceased rightly and the following recovery went smoothly.
文摘Congenital chylothorax, a condition in which chyle accumulates in the pleural cavity, is extremely rare. The reported incidence is 1 in 24,000 births. Medical treatment using octreotide as well as chemical and surgical pleurodesis has been reported, but also few reports on the successful use of Sildenafil exists. We herein report a case of congenital chylothorax referred to our Hospital at 7 days-old. Sildenafil was introduced on day 6 post intubation. Before the introduction of sildenafil, the peak total daily drainage was 106 ml/kg/day (340 mls/day), and after sildenafil was introduced, the total daily drainage dropped progressively to 10 ml/kg/day by day 11 post intubation. This case report highlights the successful use of oral Sildenafil for treatment of congenital chylothorax and also peculiarities of management related to a resource- constrained developing country setting in Africa.
文摘We present a unique case of a 49-year-old woman presenting with a bilateral chylothorax sustained after minor injury. This condition developed secondarily to minor neck injury which resulted in left side cervical swelling. First treatment was conservative. Surgical intervention was nevertheless necessary to remove a cervical cyst contiguous with the thoracic duct.
文摘Lymphoscintigraphy readily provides confirmation of chylothorax but not detailed localization of the leakage site. A 77-year-old woman developed traumatic chylothorax and underwent lymphoscintigraphy with radiolabeled albumin to identify the site of lymph leakage. Dynamic imaging demonstrated appearance of focal activity presumably in the upper mediastinum, followed by spread to the left hemithorax. Subsequently, SPECT/CT showed that the leakage site was located in the left side of the upper mediastinum, and this location was confirmed during video-assisted thoracoscopic surgery. Dynamic imaging demonstrated the site of first appearance of abnormal activity, and SPECT/CT enabled detailed localization of the abnormal activity with anatomic correlation. The combination of dynamic imaging with SPECT/CT appears to be recommendable for lymphoscintigraphic assessment of chylothorax.
文摘Background: Chylothorax may be primary (spontaneous) or secondary and more often arising as a postoperative complication of thoracic surgery. It occurs when the thoracic duct or its lymphatic tributaries become blocked or perforated or divided resulting in a chylous pleural effusion. Loss of chyle leads to nutritional deficiencies, dehydration, ionic perturbation and lymphocytes leaks thus increasing the vulnerability for infections and respiratory dysfunction. It is a life-threatening complication increasing the postoperative hospital stay. Management of chylothorax is firstly medical which leads to the cessation of leaks in most of the cases. Surgical treatment by thoracic duct ligation is sometimes necessary after failure of medical treatment. The appropriate time for surgical treatment is a subject of controversy. Methods: Reviewing a series of patients treated between 2000 to 2010 in a single center with the same protocol management, the aim of the study was to identify early clinical variables allowing early surgical treatment in postoperative chylothorax. Results: Thirty-two patients were identified in the study period. There were 21 males (65.6%) and 11 females (34.4%) with a mean age of 55.7 years (range from 9 to 79 years) (Table 1). Twenty-two patients (68.75%) had chylothorax after a surgical intervention, seven patients (21.8%) had chylothorax due to medical causes and three patients (9.3%) after chest trauma. Thirty-eight percent of patients treated conservatively were after lung cancer resection and 35% of patients treated surgically where after esophageal resection. Chylothorax was stopped in 33% of patients after lymphangiography. Cumulative leak per day was 1007 ml/day for operated patients and 397 ml/day for patient treated conservatively. Esophageal resection surgery and the amount of fluid leak were the two factors founded to be associated for the decision of an earlier surgical treatment. Conclusion: Chylothorax arising after esophageal resection with a flow rate of leak of more than 500 ml/day should be proposed to an earlier surgical treatment. Lymphangiography remains a key stone assessment with a double aim diagnostic and therapeutic in chyle leakage.
文摘Introduction: Congenital chylothorax, defined by the presence of chyle in the pleural cavity, is a rare congenital disorder of varying severity. The objective of this study was to report a case of idiopathic congenital chylothorax treated with povidone iodine effectively without side effects after failure of conservative treatment by chest drainage. Case presentation: A term female Newborn was admitted in the neonatal intensive care unit at 16 days of life, for respiratory distress. The Clinical examination objectified a Sliverman score of 3/10 with a pleural effusion syndrome. The chest radiography confirmed the pleural effusion and the analysis of the pleural fluid after aspiration confirmed the chylothorax, with a protein rate of 35 g/l, Triglycerids 37 mg/L, and Leukocytes count was 1140/ml with 90% lymphocytes. A chest drainage was performed on the seventh day but followed by the recurrence of the effusion. The use of 5 ml of 4% povidone iodine in the pleural space as a chemical pleurodesis was performed. The clinical and radiological evolution was favorable after 24 hours without relapse or side effects such as allergic reaction or worsening of the respiratory condition. Thoracic ultrasound was performed after 15 days, having objectified minimal right side effusion measuring 5 mm maximum thickness. Conclusion: Chemical pleurodesis by the polyvidone iodine in the chylothorax appears to be affordable and effective, and needs to be more considerate in the conservative treatment of congenital chylothorax.
文摘Chylothorax is a rare complication of neck dissection, and bilateral chylothorax is even rarer. However, both are potentially serious and sometimes life-threatening, especially those that are associated with left neck dissection for head and neck neoplasms. We report one case of bilateral chylothorax following left supraclavicular dissection for breast cancer. This case was treated successfully with a new conservative management approach.
