Nano Carbon Tracer in the Repairing of Congenital Abdominal Chylorus Leakage.

Congenital chylous ascites (CCA) is a rare cause of ascites in newborn infants. The main causes include congenital lymphatic obstruction due to atresia or stenosis of the major lacteals, mesenteric cysts and lymphangiomatosis. The mainstay of treatment for CCA is conservative management including medium-chain triglycerides (MCT)-based diet or total parenteral nutrition (TPN), and the addition of octreotide. Surgical exploration is reserved for those cases in whom conservative management has failed. The core problem of chylous abdominal surgery is to find the leakage; once the exact chylous leakage is found, the problem will be solved. The authors used a new carbon nanopartides material to accurately locate the location of chylous leakage. The operation is simple and fast, easy to use, and the effect is remarkable.

Management of large congenital chylous ascites in a preterm infant: fetal and neonatal interventions.

Congenital chylous ascites is a rare cause of ascites in newborn infants. Its aetiology varies from localised leaky lymphatic duct to genetic syndromes. Most of these cases have transient ascites resolving over time with conservative management but some may progress needing medical as well as surgical treatment. We describe a case of antenatally detected large fetal ascites necessitating abdominal paracentesis and amnioreduction. Marked respiratory distress at birth required urgent abdominal paracentesis to relieve symptoms. The infant initially showed a good response to medium chain triglyceride (MCT) based formula milk feeds. Feeds were discontinued for 3 weeks due to sepsis with ileus. On recovery, recommencement of feeds resulted in reaccumulation of ascites. As the response to MCT-based formula was inadequate, octreotide therapy was initiated. Ascites showed remarkable resolution over the next 2 weeks and was discharged home. Follow-up at 5 years of age revealed normal growth and neurodevelopment.

Retroperitoneal exploration with Vicryl mesh and fibrin tissue sealant for refractory chylous ascites.

BACKGROUND: Congenital chylous ascites poses a significant challenge in neonatal care, and often results in prolonged, complex hospital stays and increased mortality. Few effective options exist in refractory cases. METHODS: Patients aged 0 to 12 months with refractory chylous ascites underwent retroperitoneal exploration after medical treatment and minimally invasive therapies were unsuccessful. The retroperitoneum was completely exposed via left and right medial visceral rotation and opening the lesser sac. Visible leaks were ligated, and alternating layers of fibrin glue and Vicryl mesh were used to cover the entire retroperitoneum. RESULTS: All 4 patients had resolution of their chylous ascites. None required reoperation or reintervention for chyle leaks. All achieved goal enteral feeds at a median of 29 days postoperatively and were discharged from hospital at a median of 42 days postoperatively. CONCLUSIONS: Management of chylous ascites is extremely challenging in refractory cases. Complete retroperitoneal exposure with fibrin glue and Vicryl mesh application offers a definitive, reliable therapy for achieving cessation of lymphatic leakage and ultimate recovery for patients who fail all nonoperative approaches. STUDY TYPE: Therapeutic. LEVEL OF EVIDENCE: IV.

A female infant with phacomatosis pigmentovascularis and congenital chylous ascites: A case report.

RATIONALE: Phacomatosis pigmentovascularis (PPV) is a rare syndrome characterized by capillary malformation and pigmentary nevus. Congenital chylous ascites (CCA) is also a rare disease that results from maldevelopment of the lymphatic system. We report a case of a 5-month-old girl, who had both PPV and CCA. PATIENT CONCERNS: A 5-month-old girl is reported, who presented extensive nevus flammeus and an aberrant Mongolian spot with congenital chylous ascites. DIAGNOSES: The expression of extensive nevus flammeus and an aberrant Mongolian spot with congenital chylous ascites, that was diagnosed as type IIb phacomatosis pigmentovascularis. INTERVENTIONS: Conservative treatment included administration of somatostatin, MCT-based diet or TPN with drainage of ascitic fluid. Surgery was taken into account after failed conservative treatments. Before surgery, it is necessary to locate the abnormal lymphatic vessels. OUTCOMES: Conservative treatment and surgery sometimes functioned limitedly on CCA. LESSONS: According to the classification system of ISSVA (the International Society for the Study of Vascular Anomalies), this case meet the classification of CLM included in combined vascular malformations. It is likely to there is a connection between these two congenital diseases.

Congenital chylous ascites in infants: another presentation of intestinal malrotation.

OBJECTIVE: The cause of the chylous ascites in infants isn't completely clear. The purpose of this study is to discuss our experience of recognition of intestinal malrotation as a cause of congenital chylous ascites in infants. METHODS: Medical information of 10 infants with chylous ascites, who were admitted to the hospital between 2001 and 2014, was retrospective analyzed. Preoperatively, all patients underwent a period of conservative treatment. RESULTS: We found that nine of ten patients with intestinal malrotation, six of them underwent laparoscopic Ladd's procedure and three patients underwent open Ladd's procedure. The remaining one patient suffered from mesenteric lymph nodes rupture and laparoscopic resection was performed. The cylous ascites subsided in all patients after the surgery and no significant recurrence was encountered during follow-up time. CONCLUSIONS: Our study demonstrates that congenital chylous ascites could be caused by intestinal malrotation, causing the obstruction of the lymphatic flow in the mesenteric lymphatic channels. Ladd's procedure maybe a safe and effective treatment for infantile intractable chylous ascites. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level IV.

Refractory Chylous Ascites Secondary to Neuroblastoma.

BACKGROUND: Neonatal ascites is a complex condition that often poses a diagnostic dilemma for the clinician. We present a case of neonatal ascites secondary to neuroblastoma. CASE PRESENTATION: Our neonatal patient had congenital and recurrent chylous ascites despite multiple postnatal paracenteses, which resolved with complete resection of a retroperitoneal neoplasm. CONCLUSION: Congenital neuroblastoma may present with chylous ascites, probably due to disruption of the lymphatic vasculature.

Parenteral nutrition combined with rice soup can be a safe and effective intervention for congenital chylous ascites.

Congenital chylous ascites in the neonatal period is a rare entity. Total parenteral nutrition (TPN), medium chain triglyceride (MCT)-based diet, octreotide and repeated paracentesis are regarded as appropriate medical treatment for congenital chylous ascites, and surgery is recommended when conservative therapy has failed. We present two cases in which ascites were confirmed via an abdominal sonogram and diagnostic paracentesis. In our clinical experience, rice soup combined with PN can be a safe and effective intervention.

[CONGENITAL CHYLOUS ASCITES: A CASE REPORT].

Congenital chylous ascites is a rare polietiologic entity, requiring close study of the infant's organism by visualization methods in order to diagnose the bening or malignant underlying pathology. In the article is given a report on case of congenital chylous ascites in infant, caused by lymphangioma in the peritoneal cavity. Atypical clinic and the lack of diagnostic standards led to the later detection of the ascite's origin.

Evaluation of lymphatic dysplasia in patients with congenital pleural effusion and ascites using indocyanine green lymphography.

OBJECTIVES: To investigate the use of indocyanine green (ICG) lymphography in the diagnosis and assessment of the severity of lymphatic dysfunction in infants and neonates with congenital lymphatic pleural effusion and ascites. STUDY DESIGN: We performed ICG lymphography on 10 neonates and infants with congenital lymphatic pleural effusion and ascites. After the subcutaneous injection of ICG, circumferential fluorescent images of lymphatic drainage channels in the extremities and trunk were identified using an infrared camera system. The lymphographic findings were classifiable into 2 patterns-those showing a linear lymphatic pattern, suggesting normal lymphatic flow, and those showing lymphatic channels with retrograde lymphatic flow (dermal backflow pattern), suggesting an abnormal lymphatic flow. We analyzed the severity of the ICG lymphography findings and the clinical outcomes. RESULTS: Based on the ICG lymphography, the severity of lymphatic dysplasia were classified into 4 categories: mild dysplasia, moderate dysplasia, severe dysplasia, and lymphatic hypoplasia. All cases diagnosed with mild (n = 3) or moderate dysplasia (n = 2) survived, and 2 of the 4 cases diagnosed with severe dysplasia died. The duration of endotracheal intubation ranged from 1 to 17 days (median, 7) in the patients with mild or moderate dysplasia and from 25 to 110 days (median, 77) in those with severe dysplasia. CONCLUSIONS: The ICG lymphographic findings were consistent with the clinical conditions. This imaging technique may be important to the future clinical management of lymphatic dysplasia in neonates and infants.

Congenital chylous ascites: a report of a case treated with hemostatic cellulose and fibrin glue.

We report a case of an infant with recurrent chylous ascites who was unresponsive to conventional medical treatment. An exploratory laparotomy revealed no macroscopically visible sites of lymph leakage that could be ligated. Lymph exudation was noted in areas near the subhepatic recess and in the lesser sac surrounding the pancreas, which was not amenable to suture. The treatment consisted of the placement of a hemostatic mesh composed of oxidized cellulose (Surgicel) on these areas, with a thin layer of fibrinogen/thrombin glue over the mesh (Tissucol). The cellulose mesh allowed for greater adhesion of the fibrin glue to the diseased tissues. The patient had no recurrence of ascites and is currently 20 months old, with good weight-height gain, and free of ascites.

Successful management of congenital chylous ascites with early octreotide and total parenteral nutrition in a newborn.

Congenital chylous ascites (CCA) is a rare disease that results from maldevelopment of the intra-abdominal lymphatic system. Few cases have been described and no gold standard treatment has been defined so far. Octreotide, a somatostatin analogue, has been used for the treatment of CCA, but always after a failed conservative approach with fasting, total parenteral nutrition (TPN) or medium chain triglyceride (MCT) feeds. We report the case of a newborn with CCA treated by fasting, TPN and octreotide for a period of 15 days until the abdominal distension was successfully reduced at which point treatment was switched to an MCT formula. On day 25 the patient was breastfed and was discharged on day 33. No recurrence of chylous ascites was noted. Our experience highlights the successful treatment with TPN and octreotide as the first step for the conservative approach of CCA in a newborn, reducing the length of treatment and hospitalisation.

Congenital fetal and neonatal visceral chylous effusions: neonatal chylothorax and chylous ascites revisited. A multicenter retrospective study.

This retrospective study was carried out at eight Neonatal Intensive Care Units (NICU) Centers worldwide on 33 newborns presenting at birth with pleural, pericardial, or abdominal chylous effusions. Diagnosis of chylous effusion is based on findings of fluid with a milk-like appearance, a concentration of triglycerides in pleural effusion >1.1 mmol/l, and a total cell count >1,000 cells/ml with a predominance of >80% lymphocytes. Thirty-three newborns met the inclusion criteria and were studied. Six subjects who presented at birth with fetal effusion were treated by in-utero pleuro-amniotic shunt. Five of these patients are alive at follow-up. At birth, pleural drainage was performed in 29/33 patients and abdominal drainage was carried out in 3/33. Total parenteral nutrition (TPN) was given to 32/33 patients; 19/23 patients were fed a medium-chain triglycerides (MCT). No adverse effects were observed. Eight patients were treated with Octreotide at dosages ranging from 1 to 7 mcg/kg/hour for 8 to 35 days. All patients showed decreased chylous production. Two patients were treated by pleurodesis. Twenty-two babies are alive after at least 6 months follow-up, 9/33 are deceased, and 2 were lost to follow-up. Clinical conditions of survivors are basically good except for lung involvement [chronic lung disease (CLD) or lung lymphangiectasia] and lymphedema. All patients were using a MCT diet at follow-up with good control of chylous effusion. Visceral chylous effusions of the fetus and neonate are rare disorders, and there currently is only partial agreement on decision-making strategies. We suggest the need for an international prospective trial in an effort to establish the efficacy and effectiveness of diagnostic and therapeutic options described in this article.

Preoperative administration of Sudan III and successful treatment of persistent chylous ascites in a neonate.

Congenital chylous ascites is a rare entity, and surgical treatment is confined to selected intractable cases. We report 2 cases of refractory congenital chylous ascites successfully treated with preoperative administration of lipophilic dye (Sudan III) followed by abdominal systematic surgical exploration, cauterization, and fibrin glue application.

Successful management of congenital chylous ascites in a premature infant using somatostatin analogue.

Congenital chylous ascites (CCA) is a rare disease defined as the accumulation of chylomicron-rich lymphatic fluid within the peritoneal cavity, resulting from maldevelopment of the intra-abdominal lymphatic system. Cases unresponsive to conservative treatment usually require surgical intervention. We report a case of CCA in a premature neonate, who was treated successfully with intravenous infusion of octreotide, a synthetic somatostatin analogue after failure to response to traditional supportive therapies.

Refractory congenital chylous ascites.

Refractory congenital chylous ascites (CCA) is an uncommon clinical condition. Few cases have been described and no gold standard treatment has been defined so far. This report describes a case of refractory CCA in a newborn child which was treated by surgery. Preoperative lower-limb lymphoscintigraphy associated with intraoperative patent blue testing and fibrin glue application were useful in order to provide a successful outcome.
