Chylothorax complicating left lower sleeve lobectomy.

Postoperative chylothorax is an infrequent but potential life-threatening complication and has most often been described following oesophageal resection. Its incidence after pulmonary resection is low, but has increased to 0.3-0.5%, probably due to more extensive types of resections and radical lymph node dissections. We report a case of chylothorax after a left sleeve lobectomy for a primary bronchogenic carcinoma, that was treated conservatively with chest tube drainage and a diet of medium chain triglycerides. Five additional case reports in English and French literature confirmed chylothorax after bronchoplastic procedures to be extremely rare. More frequent use of bronchial sleeve resection as alternative to pneumonectomy to save functional lung tissue, can increase the incidence of chylothorax after bronchoplastic procedures.

Resolution of chylothorax after positive end-expiratory pressure ventilation.

Ligation of the thoracic duct has previously been recommended for adults with traumatic chylothorax when average daily chyle loss exceeds 1,500 mL/day over five days since such cases are usually refractory to medical management. We describe a case of traumatic chylothorax where chyle output exceeded 2 L/day for a week despite cessation of oral intake and institution of intravenous hyperalimentation. The chylothorax rapidly resolved when mechanical ventilation with positive end-expiratory pressure was begun for treatment of an acute respiratory distress syndrome. The artificial ventilation may have promoted tamponade of the injured lymphatic duct thereby accounting for the abrupt decrease in chyle flow the occurred.

Chylothorax in chronic lymphocytic leukemia patient.

Chronic lymphocytic leukemia (CLL) is rarely complicated by chylothorax: we present a 93-year-old woman with CLL who developed recurrent pleural effusions that were ultimately found to be chylous in nature. Despite eight repeated thoracenteses, she continued to experience re-accumulation of fluid, and therefore, video-assisted thoracotomy with mass ligation of the thoracic duct region plus pleurodesis was performed to resolve the chylothorax. Despite her age and underlying disease, she did well during follow-up. The etiology and management of chylothorax are also reviewed.

Bilateral chylothorax complicating radical neck dissection: report of a case with no concurrent external chylous leakage.

Bilateral chylothorax as a complication of radical neck dissection is extremely rare. Six cases are reported in the English literature. All of these patients' cases were associated with a concurrent external chylous fistula, as evidenced by the appearance of a milky fluid confirmed to be chyle by chemical determination. Chyle had also been noted to leak during the operation. This presentation illustrates an additional case of bilateral chylothorax occurring after radical neck dissection, and the first case, to our knowledge, with no concurrent external lymph leakage. Anatomic and physiologic considerations are presented and possible mechanisms of pathogenesis are discussed. Chylothorax has two major complications--respiratory and metabolic. A short summary of the modern concepts of treatment is presented.

Chylothorax in the neonatal period.

Chylothorax is defined as an effusion of lymph in the pleural cavity. In the neonate both congenital and traumatic (iatrogenic) forms exist. Birth asphyxia and respiratory insufficiency are major symptoms of congenital chylothorax, requiring resuscitation and artificial ventilation. Antenatal diagnosis by ultrasound allows early therapeutic intervention such as ventilatory support and drainage of chylous fluid immediately after birth. Traumatic chylothorax is mainly seen after intrathoracic surgery. Treatment primarily consists of continuous or intermittent drainage of chyle with replacement of fluid-, electrolyte-, and protein losses and parenteral nutrition. Introduction of oral feeding is considered only after a substantial period without chyle production in the pleural cavity and consists of a medium-chain triglyceride containing formula. In a minority of cases surgical intervention is necessary.

Congenital chylothorax in a trisomy 21 newborn.

We here report a case of trisomy 21 with congenital chylothorax. The patient was a male newborn who had been diagnosed as having trisomy 21 with congenital chylothorax. This is the fifth case of the both conditions in English literature. Congenital chylothorax is very rare in a trisomy 21 patient. There, however, may be causal relationship between the two conditions.

Advantage of earlier thoracoscopic clipping of thoracic duct for post-operation chylothorax following thoracic aneurysm surgery.

We report that an earlier thoracoscopic clipping of the thoracic duct was advantageous in a case of post-operation chylothorax that occurred following thoracic aneurysm surgery. A 61-year-old man developed chylothorax on postoperative day 2 following graft replacement of the descending thoracic aorta using a left-sided thoracotomy. Since a replaced graft infection is lethal, earlier thoracoscopic clipping of the thoracic duct through the right side chest wall was indicated. The patient underwent thoracoscopic clipping on postoperative day 7 and was successfully treated. The duration of drainage was 2 days and oral intake was started on the seventh day. From our results, we recommend a thoracoscopic procedure through the opposite (right) side chest wall in the early stage of chylothorax development following thoracic aneurysm surgery.

Congenital chylothorax treated with octreotide.

Congenital chylothorax is the accumulation of lymphatic fluid within the pleural space. Cases unresponsive to conservative management usually require surgery. Octreotide has been used successfully to treat post-traumatic chylothoraces in the pediatric and adult population. Its exact mode of action is uncertain but it is believed to reduce lymphatic drainage by a direct action on splanchnic lymph flow. We report a case of congenital chylothorax where surgery was avoided with the compassionate trial of the somatostatin analogue, octreotide. A 33 week gestation female infant, born with the presence of large bilateral pleural effusion, was unresponsive to conservative management. Octreotide was commenced on day 15, with 10 days of an octreotide infusion, initially 0.5 microg/kg per hour and increased daily by 1 microg/kg per hour to 10 microg/kg per hour. Treatment was associated with prompt respiratory improvement prior to cessation of pleural drainage over the 10 day. She remains well at 6 months of age. Further studies are required to ascertain its true value in congenital chylothorax.

Localization of chyle leakage site in postoperative chylothorax by oral administration of I-123 BMIPP.

The authors present a 71-year-old woman who had a right chylothorax after right upper lobectomy for lung cancer. As the chylothorax was considered to be due to thoracic duct injury at the time of operation, lymphoscintigraphy was performed by oral administration of I-123 beta-methyl-iodophenyl pentadecanoic acid (BMIPP). After visualization of the stomach and intestine, abnormal accumulation of the radiotracer was found initially around the right pulmonary hilum and then spread laterally in the upper pleural cavity, indicating chyle leakage in the region of the right pulmonary hilum. Scintigraphic finding was well correlated with the subsequent thoracoscopic observation, showing chyle leakage from a lymphatic tributary near its confluence to the thoracic duct at the level of the azygos continuation. The disruption site was ligated by video-assisted-thoracoscopic-surgery procedure with successful termination of the chyle leakage. Lymphoscintigraphy by oral administration of I-123 BMIPP is thought to be a useful method for localization of chyle leakage in patients with chylothorax induced by thoracic surgery.

[Persistent chylothorax after fracture of the 12th thoracic vertebrae].

We report on a patient who suffered chylothorax 2 months after she had undergone internal fixation of a fracture of her 12th thoracic vertebral body. The pleural effusion was treated by insertion of a chest tube. The chylothorax was managed conservatively. The patient received protein-rich nutrition supplemented with medium-chain triglycerides. As the volume of chylous fluid drained from the pleura had not decreased after 2 weeks, the patient received total parenteral nutrition without any oral intake of calories. Chest X-rays documented the disappearance of the chylothorax. Reexpansion of the lungs was noted, and the costophrenic sinuses could be clearly visualised.

Somatostatin: a new therapeutic option for the treatment of chylothorax.

BACKGROUND: The standard treatment of chylothorax in pediatric intensive care today includes conservative therapy with fat-free nutrition, total parenteral nutrition and, if this is not successful, operative treatment (pleurodesis, ligation of the duct, pleuroperitoneal shunt). PATIENTS: We describe four patients who were not in a suitable condition for operative treatment and who were treated with continuous infusion of somatostatin. RESULTS: In three patients, chylothorax ceased with the continuous somatostatin infusion without side effects. One patient was treated without success. CONCLUSIONS: Somatostatin is a therapeutic option for treatment of chylothorax and could reduce surgical intervention and hospitalization time, as well as allow earlier enteral feeding.

The effectiveness of octreotide in the treatment of post-operative chylothorax.

UNLABELLED: Chylothorax may be spontaneous or a complication of thoracic surgery. Treatment of this potentially harmful condition is not well established and may comprise dietary interventions and surgery. Somatostatin seems effective in the management of chylothorax, although its mechanism of action is unclear. CONCLUSION: octreotide, a somatostatin analogue, may be effective in the treatment of post-operative chylothorax.

Late-onset chylothorax after pulmonary resection and systematic mediastinal lymph node dissection for lung cancer.

Late-onset chylothorax occurred 49 days after right lower lobectomy for lung cancer in a 76-year-old man. Chylothorax was successfully managed by conservative treatment with chest tube drainage and an enteral low-fat diet. Chylothorax may occur in the late period after pulmonary resection and systematic mediastinal lymph node dissection for lung cancer, for which conservative management is the treatment of choice.

Pleuroperitoneal shunts for refractory chylothorax after operation for congenital heart disease.

Between 1980 and 1990, 10 of 12 children with a symptomatic chylothorax after operation for congenital heart disease failed to respond to traditional medical therapy (thoracentesis, tube thoracostomy, low-fat diet). All 10 patients underwent placement of a pleuroperitoneal shunt, with complete resolution of the chylothorax in 9 patients (90%). Cardiac catheterization, performed before placement of the pleuroperitoneal shunt in 5 patients, demonstrated elevated right atrial pressure in all patients (range, 10 to 25 mm Hg). The pleuroperitoneal shunt functioned effectively in 4 patients with moderately elevated right atrial pressures (range, 10 to 16 mm Hg; median, 13.5 mm Hg) but not in 1 patient with a right atrial pressure of 25 mm Hg. Pleuroperitoneal shunting as treatment for chylothorax after operation for congenital heart disease is safe and effective, even in the face of moderate elevations in right atrial pressure.

Management of pediatric postoperative chylothorax.

Questions persist about the management of postoperative chylothorax in infants and children. Our experience with postoperative chylothorax over the most recent decade (1980 to 1990) has been reviewed. The type and amount of drainage, data from cardiac catheterization and echocardiography, operative decisions and details, and eventual outcomes have been cataloged. All patients were initially treated with total gut rest, with operation reserved for unabated drainage. Chylothorax developed postoperatively in 15 infants and 11 children (18 with a cardiac procedure and 8 with a noncardiac procedure). The average age was 3.1 years. Spontaneous cessation and cure occurred in 19 (73.1%) of these 26 patients, with an average drainage duration of 11.9 days (range, 4 to 30 days). Those for whom operation was chosen drained preoperatively for an average of 29.2 days (range, 25 to 40 days). There were no deaths in either group. Complications were lymphopenia (2 patients) and fungal sepsis (1 patient). The amount of drainage per day was not significantly different between patients treated operatively and those treated nonoperatively. Failure of nonoperative management was associated with venous hypertension from increased right-sided cardiac pressures or central venous thrombosis (p < 0.05, Fisher's exact test). Presumably this increased pressure is transmitted to the lymphatic system. These patients should be identified early and considered for thoracic duct suture or pleuroperitoneal shunting.

Dietary modification of chyle composition in chylothorax.

Nutrition support has played a major role in the treatment of chylothorax, both to prevent malnutrition and to minimize chyle production and flow. This report evaluates chyle composition in a patient with chylothorax who was placed on a low-fat diet, medium-chain triglyceride diet, and total parenteral nutrition in sequence. Both triglyceride content and volume of chyle declined, but drainage persisted, ultimately requiring thoracic duct ligation. The chyle triglyceride while on total parenteral nutrition, which presumably originates from both the intestine and plasma, contained more long-chain unsaturated fatty acids than the circulating serum triglyceride. Of particular interest was the detection of an appreciable amount of medium-chain fatty acids in the chyle triglyceride, constituting 20% of the triglyceride fatty acids when an enteral formulation with medium-chain triglyceride as a sole fat source was administered. The finding of almost threefold more decanoic acid (C10:0) than octanoic acid (C8:0), despite the presence of considerably more octanoic acid in the original diet, suggests that trioctanoin may be a preferable medium-chain triglyceride substrate for the nonsurgical treatment of chylothorax.

Congenital chylothorax and mediastinal neuroblastoma.

This is the first reported association of congenital chylothorax and mediastinal neuroblastoma in a newborn infant. The infant exhibited features of both congenital and acquired chylothorax. Resolution of the chylothorax occurred following ligation of thoracic duct after failure of conservative management with multiple thoracentesis and chest tube drainage.

Very unusual case of post-traumatic chylothorax.

Chylothorax is a rare disease caused by both traumatic and nontraumatic events. Chylothorax can cause cardiopulmonary abnormalities and significant nutritional, metabolic, and immunologic consequences. We present an exceptional case of chylothorax due to penetrating chest trauma. The diagnosis was made by thoracentesis. Conservative management with nothing by mouth and total parenteral nutrition failed; therefore the patient needed surgical closure of the duct leak.
