[Chylous ascites: a rare and awesome complication of aortic surgery].

Chylous ascites is a rare complication in abdominal aortic surgery, there have been thirteen previously reported cases of chylous ascites after aortic surgery, both for aneurysmectomy or revascularization. This complication always represents a difficult problem in patient management because of the serious failures of the nutritional balance, the potentially dangerous immunological deficit and the frequent respiratory function impairment overcoming with various mechanisms. Analysis of ascitic liquid, which shows the aspect and chemical composition of chyle, is required to make the diagnosis. Several therapeutic pathways are possible for the treatment of this complication (paracentesis, reinfusion of chyle, diuretics, total parenteral hyperalimentation, medium-chain triglyceride diet, peritoneovenous shunt, operative closure) and the choice results in an association which is specific for each patient. This article describes a further case of postoperative chylous ascites after aortic surgery and envisages the main lines of the treatment of this iatrogenic pathology.

[Surgical management of chylothorax: a report of 65 cases].

Sixty-five cases of chylothorax treated at the Shanghai Chest Hospital over the past 30 years are reviewed. The causes of chylothorax in this series were mainly traumatic and postoperative (47/65). Two cases were associated with chylopericardium and another 2 with chylous sputum. The authors believe that untreated chylothorax is a serious, often life-threatening entity and that the following principles are applicable in its management: (1) If daily chyle loss exceeds 1000 ml in adults with no tendency of subsidence, surgery is indicated especially in the effusion may lead to disastrous nutritional and immunologic consequences; (2) Ligation of the thoracic duct is effective by a mass ligature encircling all tissues between the azygos vein and the aorta. The most favorable site for ligation is immediately above the diaphragm. Over dissection of the thoracic duct should be avoided; (3) The proper surgical approach is on the side of the effusion in unilateral chylothorax, but right side approach is preferred in case of bilateral chylothorax or when the origin of chylous fistula is unknown; (4) Pleurodesis is indicated for those cases if the duct is not obviously present or chyle comes from the pleural lymphatics. Concentrated glucose solution with or without Talc suspension is recommendable.

Origin of milk cholesterol in the rat: dietary versus endogenous sources.

Slices of mammary gland from lactating rats, incubated with acetate-1-(14)C or mevalonate-2-(14)C, synthesized cholesterol-(14)C. Within 2 min of an intravenous injection of 1 ml of a suspension of chylomicrons containing cholesterol-4-(14)C, mammary glands of lactating rats removed as much as 29% of the labeled cholesterol; those of 2-day-postlactating rats removed none. Rats were fed a diet containing 0.05% cholesterol-4-(14)C from 7 days prepartum to 20 days postpartum. At isotopic equilibrium, the relative specific activities of milk and dietary cholesterol indicated a dietary origin for 11% of the milk cholesterol. The extent to which endogenous sources-liver and mammary gland-contributed cholesterol to milk proved entirely dependent on whether dietary cholesterol, in the form of chyle lipo-proteins, was first processed by liver or taken up directly by mammary gland. Lack of information regarding the extent to which chyle cholesterol is removed from blood under physiological conditions by mammary gland and other tissues precludes precise assessment of the endogenous contributions to milk cholesterol and, moreover, casts doubt on the quantitative interpretability of cholesterol-(14)C-feeding experiments reported in the literature.

[Pulmonary lymphangioleiomyomatosis. Case report].

Pulmonary lymphangioleyomiomatosis (LAM) is a rare disease that affects only women. About one hundred cases are reported in the literature. This disease progresses to respiratory failure and its course can be slowed by hormonal therapy. A new case is reported; this woman was admitted to our Division for a right hydropneumothorax and after pleural drainage fluid demonstrated to be a chylous effusion; after a thoraco-abdominal CT scan the diagnosis of LAM was suspected. She was operated on after a few days because of continuous air and chyle leakage. A closure of lung leakage was performed with a stapler device that allowed the removal of a small specimen of lung for histopathological examination and a parietal pleurectomy was added with the aim of obtaining a pleural space obliteration. The histopathological examination revealed changes consistent with LAM and also positive was the hormonal steroid receptors assay. Adhesion of the lung to the chest wall was obtained but an antero-basal pouch persisted with continuous chylous leakage. A transposition of omentum into the chest was made with the aim of obliterating the pouch and favour chyle reabsorption and no drainage was left. Another CT scan demonstrated complete obliteration of the pouch and no fluid accumulation; the procedure proved to be successful and the patient was discharged with hormonal therapy.

Chylothorax: therapeutic alternatives.

Persistent loss of chyle, rich in metabolites, water and electrolytes, can be quickly devastating, particularly in debilitated patients and children. Chylothorax of traumatic origin, especially when loss of chyle is rapid, is most effectively arrested with direct closure of the fistula or ligation of the thoracic duct. Thoracic duct ligation is indicated when a controlled fat diet or parenteral hyperalimentation without oral intake and closed chest drainage are not effective in arresting chylous pleural effusions.

Systematic approach to the treatment of chylous leakage after neck dissection.

BACKGROUND: Chylous leakage is an uncommon complication after neck dissection for which several treatment modalities have been described in literature. It occurs in 1% to 2.5% of radical neck dissections, with the majority (75% to 92%) being on the left side. In a consecutive series of patients, we investigated the effect of a systematic approach to the complication. METHODS: Over a period of 5 years, the drain production of 221 patients who underwent a neck dissection was analyzed. One hundred thirty-two right-sided and 139 left-sided neck dissections were performed. In 11 patients a chyle fistula occurred, 1 right-sided and 10 lift-sided. In all cases closed vacuum suction drainage was continued and dietary modifications (medium-chain triglycerides [MCT]/Peptison nasogastric tube feeding [PNTF]) were made. RESULTS: In 5 patients dietary modifications were sufficient to stop the leak. In the other 6 patients total parenteral nutrition via the subclavian vein (TPN) was started. In 2 cases with a severe intractable hypoalbuminemia, surgical intervention was necessary. The leak was closed by a pectoralis major muscle flap transfer, after local application of fibrin sealant (Tissucol). CONCLUSIONS: Chylous leakage is a controllable complication after neck dissection for which is most cases a stepwise conservative approach consisting of dietary modifications, maintaining closed vacuum suction drainage, seems to be sufficient. Hematologic and serum values should be monitored very carefully and corrected appropriately. To initiate planned postoperative radiotherapy in a timely fashion, the conservative treatment should be limited to about 30 days.

Post-mastectomy chylous fistula: anatomical and clinical implications.

A chylous fistula after a modified radical mastectomy is a rare occurrence; however, major anatomical variations in the termination of the thoracic duct may occur, rendering it susceptible to injury. High output chylous fistulae are difficult to manage and have local, metabolic, and immunologic complications with a mortality rate varying from 12.5-50%. Herein such a case of postmastectomy chylous fistula and its management are discussed. A 56-year-old postmenopausal woman with invasive duct carcinoma of the left breast underwent modified radical mastectomy with complete axillary clearance (Level I, II, III nodes). The operative procedure was uneventful. On the commencement of a normal diet, however, the patient started exuding milky fluid from the axillary drain and analysis of the fluid revealed biochemical features compatible with chyle. After 2 weeks of failed conservative management, the axilla was re-explored. A continuous flow of clear fluid was observed originating from a single major lymphatic trunk inferior to the axillary vein in the region of the former Level II nodes. The leak was controlled by the application of multiple mass ligatures using 2-0 silk suture. A part of the pectoralis major muscle was rotated and sutured over the area of the leak as additional reinforcement. Suturing a muscle flap over the leak has been described previously and functions theoretically by causing fibrosis. The chylous fistula in the present case was managed successfully with mass ligatures and muscle flap reinforcement.

Primary chylous vaginal discharge in a 9-year-old girl: CT-lymphangiogram and MR appearance.

Chylous reflux is a manifestation of primary or secondary lymphatic obstruction. Primary lymphatic obstruction is defined as lymphangiectasia and incompetency of lymphatic valves without an underlying cause. Lymphangiectasia resulting from trauma, neoplasm, irradiation, or inflammation characterizes secondary lymphatic obstruction. Leakage of chyle into the uterus, vagina, bladder, or rectum can occur with either primary or secondary lymphatic obstruction. We report a patient with chylous vaginal discharge, a rare presentation of primary chylous reflux syndrome. CT-lymphangiography and magnetic resonance imaging clearly depicted this disorder. To our knowledge, only 20 cases of chylous vaginal discharge have been reported previously; chylous vaginal drainage occurred in the absence of chylous uterine reflux in only three. Although this is a rare anomaly, chylous reflux should be considered in a child with chronic vaginal discharge and lower extremity swelling.

Nontropical chyluria secondary to massive mesenteric adenitis. Case report with metabolic and immunologic studies.

This report describes metabolic and immunologic studies in a 17-year-old white man with nontropical chyluria secondary to massive mesenteric adenitis. Numerous red cells and mature lymphocytes were observed in the urine, and cystoscopic examination demonstrated chyle emanating from both ureteral orifices. Retrograde studies demonstrated pyelolymphatic backflow, and lymphangiography revealed prominent lymphaticocaliceal communications. Twenty-four-hour urinary studies showed proteinuria and lipiduria, which decreased after lymphangiography and a low-fat diet. Skin tests for delayed hypersensitivity were nonreactive, the lymphocyte count was decreased, and lymphocyte responses to phytohemagglutinin and pokeweed mitogen were normal. Chyluria ceased after interruption and ligation of the renal and mesenteric lymphatics.

Cardiac tamponade secondary to chylopericardium following cardiac surgery: case report and review of the literature.

Only four instances of isolated chylopericardium following cardiac operation have been reported previously. We encountered this complication in a young patient who was operated on for infundibular pulmonary stenosis. The etiology appears to be related to a combination of intraoperative lymphatic injury and catheter-related subclavian vein thrombosis, the latter potentially elevating pressure within the thoracic duct and thereby resulting in an accumulation of chyle within the pericardial space. Therapy for this problem usually includes partial pericardiectomy with or without ligation of the thoracic duct.

Treatment of a persistent postoperative chylothorax with somatostatin.

Chylothorax is a rare but potentially serious complication of pediatric cardiac operations. We report the case of a 4-month-old boy who underwent a Senning procedure for correction of D-transposition of the great vessels. A persistent postoperative chylothorax developed, necessitating continuous drainage, despite conservative treatment over 3 weeks. Thereafter, continuous somatostatin infusion for 14 days led to the reduction and finally cessation of chyle production. This treatment allowed early enteral feeding and avoided further surgical intervention.

Chronic chyluria: a clinical study of 3 patients.

Studies of patients with chyluria or chylothorax have demonstrated significant disruptions of protein, blood and fat metabolism that may result in iron deficiency anemia, hypoproteinemia, hypolipidemia and malnutrition. To document the sequential development of these complications we performed serial clinical and biochemical studies for 2 to 12 years in 3 patients with presumed filarial chyluria whose sole treatment had been diethylcarbamazine. Despite the chronic loss of chyle in the urine these 3 patients did not have significant complications during the period of observation. The weight and blood pressure remained stable. No persistent anemia, hypoproteinemia or hypolipidemia was noted. Except for 1 patient in whom a transient decrease of the creatinine clearance developed during pregnancy, no permanent renal function impairment occurred. These observations suggest that chronic chyluria may not always result in serious alterations of the physical status or body functions of these patients requiring surgical repair, and supports the hypothesis that untreated chyluria could be a relatively benign process in our milieu.

Bilateral traumatic chylothorax.

We report the case of a 27-year-old man with bilateral chylothorax. The patient presented with shortness of breath and bilateral pleural effusions three days after a motor vehicle accident. The diagnosis was established when tube thoracostomy revealed chylous drainage. During hospitalization approximately 8 L of chyle were removed. Bilateral chylothorax secondary to blunt trauma has rarely been reported. The etiology, pathogenesis, clinical presentation, and recommended therapy are reviewed.

Videoscopic supradiaphragmatic thoracic duct division using ultrasonic coagulator.

Three consecutive male patients underwent videoscopic supradiaphragmatic thoracic duct division using the Harmonic Scalpel with a hook blade (Ethicon Endo-Surgery, Cincinnati, OH, USA) for treatment of chyle leaks that developed after left upper lobectomy, graft replacement of a descending aortic aneurysm and thyroidectomy with concomitant partial sternal resection. The thoracic duct was exposed and divided using just the Harmonic Scalpel. The operations lasted 40, 20 and 18 min. No mortality, morbidity or recurrence occurred during follow-up periods of 27, 17 and 9 months. The Harmonic Scalpel with a hook blade can facilitate supradiaphragmatic exposure of the thoracic duct.

Unilateral pedal lymphography in patients with filarial chyluria.

OBJECTIVE: To evaluate the usefulness of unilateral pedal lymphography in patients with filarial chyluria. PATIENTS AND METHODS: Of 114 patients with filarial chyluria, all underwent lymphography (unilateral pedal in 106) and 55 underwent selective ureteric sampling for chyle. RESULTS: Unilateral pedal lymphography in the 106 patients detected lymphaticorenal fistulae (LRF) in 104 (98%). Lymphatic crossover was seen in all 106 patients, from the second sacral segment to the first lumbar segment. The most frequent crossover site was at the L5 level (87%). There was complete correlation between the side of LRF and the side of chyluria as assessed by selective ureteric sampling. CONCLUSION: Unilateral pedal lymphography can detect LRF via lymphatic crossover even when it is on the opposite side from that injected with contrast agent. The advantages of unilateral lymphography over bilateral procedures are that it is easy to identify crossover channels, and the discomfort for the patient is reduced because there are fewer incisions and it is quicker. Unilateral lymphography is recommended as the initial method when lymphography is indicated in filarial chyluria.
