Chylothorax in a Young Woman With Crohn Disease.

Chylothorax, which accounts for 1% to 3% of pleural effusions, typically results from either surgery (traumatic) or underlying malignancy (nontraumatic). Less common causes of nontraumatic chylothorax are numerous and include congenital lymphatic abnormalities, connective tissue diseases, cirrhosis, and infection, among others.1 We describe what appears to be the first reported case of chylothorax caused by chylous ascites in Crohn disease. This case highlights the importance of using diagnostic evidence to link new symptoms to preexisting diseases whenever possible, as well as the systemic nature of Crohn disease.

Diagnosis and Treatment of a 64-Year-Old Man with Chyle Leak Following Laparoscopic Cholecystectomy: A Case Report.

BACKGROUND Chyle leakage with chylous ascites is a rare complication of abdominal surgery, and few cases have been reported following cholecystectomy. This report is of a 64-year-old man with chyle leak following laparoscopic cholecystectomy and describes the diagnosis and approach to treatment. Immediate diagnosis, although challenging, remains imperative. Frequently, patients manifest nonspecific symptoms, such as abdominal discomfort or nausea. They can also exhibit milky discharge from drains and wounds. Abdominal fluid analysis is fundamental for diagnosis. The existence of elevated triglyceride levels in peritoneal fluid is indicative of chyle leakage. CASE REPORT We present a case report of a 64-year-old man with chyle leakage after laparoscopic cholecystectomy for acute cholecystitis, on postoperative day 2. A milky-white fluid was drained, and diagnosis was confirmed with elevated triglycerides upon fluid analysis. Chyle leakage decreased gradually until complete resolution at postoperative day 7, after dietary modifications and the closed-suction silicone drain was removed. The patient was symptom-free at a 2-month follow-up. CONCLUSIONS Although chyle leakage is a rare postoperative complication of laparoscopic cholecystectomy, early diagnosis and rapid multidisciplinary management are required. It is vital to consider this diagnosis even if the course of laparoscopic cholecystectomy was uncomplicated and with no anatomical variation. Thus, a closed-suction silicone drain and close monitoring of output is essential for early diagnosis. The dietary modification constitutes a cornerstone in the management of chyle leakage, and a surgical approach should be preserved for patients for whom the conservative approach fails or who have large volumes of chyle.

Acute primary chylous peritonitis mimicking acute abdomen: a case report and literature review.

Acute chylous peritonitis is an uncommon medical condition that can occur suddenly, resulting in the buildup of chylous fluid in the peritoneal cavity. It is considered idiopathic because the exact cause is often unknown. The symptoms of acute chylous idiopathic peritonitis can mimic other abdominal emergencies, making it challenging to diagnose and manage, requiring a multidisciplinary approach. We present a case report of acute idiopathic chylous peritonitis miming acute abdomen, how was successfully treated with surgery, and provide a comprehensive review of the available literature on this topic. Chylous peritonitis is a rare condition whose clinical presentation mimics an acute abdomen. It is necessary to undertake careful exploration. An emergent laparotomy is indicated to treat the peritonitis and search for and treat the underlying cause.

Chylous Ascites Associated with Advanced Pancreatic Cancer That Improved with Appropriate Treatment: A Case Report.

Chylous ascites is a rare form of ascites with high triglyceride content arising from the thoracoabdominal lymph nodes in the peritoneal cavity due to various benign or malignant etiologies, including pancreatic cancer. During cancer chemotherapy, the accumulation of ascites can lead to the deterioration of the patient's general condition, making chemotherapy administration difficult, and resulting in a poor prognosis. We encountered a rare case of chylous ascites complicated by advanced pancreatic cancer. The patient presented with a discrepancy between the shrinkage of the pancreatic cancer and the accumulation of ascites. Therefore, we were able to promptly diagnose chylous ascites by performing biochemical tests. The patient was treated with octreotide, reportedly effective in treating chylous ascites, which rapidly improved the chylous ascites and general condition of the patient, allowing the patient to continue chemotherapy for pancreatic cancer. Therefore, physicians should consider the possibility of chylous ascites when clinically unexplained ascites are observed in patients with advanced cancer. The investigation and treatment of chylous ascites should be initiated as soon as possible.

Successful Treatment of Cirrhotic Chylous Ascites using Orlistat and Dietary Modifications: A Case Study and Literature Review.

BACKGROUND Chylous ascites (chyloperitoneum), a condition arising from lymphatic leakage in the peritoneal cavity, is rare in liver cirrhosis patients, accounting for less than 1% of cases. Treatment typically involves therapeutic paracentesis, dietary modifications, a low-fat, high-protein diet, and medium-chain triglyceride (MCT) supplementation. Orlistat, a fat absorption inhibitor, has been reported to show potential efficacy in treating chylous ascites. CASE REPORT We detail the case of a 59-year-old male patient admitted for decompensated liver disease and worsening ascites. Diagnostic paracentesis identified chylous ascites, indicated by a 3.5 mmol/L triglyceride level. Despite administering therapeutic paracentesis, dietary modifications, MCT supplementation, Spironolactone, and Terlipressin for a presumed hepatorenal syndrome, the patient's ascites remained chylous for two weeks. On administering orlistat, a significant reduction in ascites volume and chylous content was observed, with triglyceride levels dropping to 0.7 mmol/L. CONCLUSIONS Our case illustrates the potential of orlistat in managing chylous ascites in liver cirrhosis patients, marking only the second such case reported in the existing literature. It encourages further exploration of orlistat's therapeutic potential in treating chylous ascites.

[Chylous ascites in NSCLC: It is not always malignant]. / Chylöser Aszites bei NSCLC: Nicht alles ist maligne, was maligne aussieht.

The etiology of chylous ascites is multifactorial. Malignant diseases, cirrhosis, trauma, lymphomatic abnormalities and mycobacteriosis are the most common causes. In NSCLC, chylous ascites is observed with peritoneal metastasis or abdominal lymph node metastases.RET alterations occur in 1-2% of NSCLC patients and since recently they can be treated in a targeted fashion.Our case report shows that new targeted therapies revolutionize prognosis, but confront us with the challenge of new and partly unknown side effects.

Diagnosis of chylous abdominal effusions: what is the triglyceride threshold value?

Introduction: Chylous abdominal effusions are serious complications that can be triggered by various aetiologies. The biochemical diagnosis of chyle leakage in ascites or in peritoneal fluid capsules relies on the detection of chylomicrons. Assaying the fluid's concentration of triglycerides is still the first-line tool. Given that only one comparative study has sought to quantify the value of the triglyceride assay for diagnosing chylous ascites in humans, our objective was to provide practical triglyceride thresholds. Materials and methods: We conducted a 9-year, retrospective, single-centre study of adult patients and compared a triglyceride assay with lipoprotein gel electrophoresis for the analysis of 90 non-recurring abdominal effusions (ascites and abdominal collections) of which 65 were chylous. Results: A triglyceride threshold of 0.4 mmol/L was associated with a sensitivity > 95%, and a threshold of 2.4 mmol/L was associated with a specificity > 95%. According to Youden index, the best threshold was 0.65 mmol/L with a sensitivity of 88 (77-95)%, a specificity of 72 (51-88)%, and, in our series, a positive predictive value of 89 (79-95)% and a negative predictive value of 69 (48-86)%. Conclusions: In our series, cut-off of 0.4 mmol/L could be used for ruling-out diagnosis of chylous effusions, while cut-off of 2.4 mmol/L could be used for reasonably confirming diagnosis.

Chylothorax and chylous ascites: Overview, management, and nutrition.

Chyle leaks of any source or type can cause significant morbidity and mortality. Attention to the anatomy and physiology of the leak, followed by stepwise dietary and pharmacologic management, obviates the need for surgical intervention in a majority of patients. In this article, we review the importance, etiology, anatomy, diagnosis, nutrition and immunologic effects, and options for treatment of chylothorax and chylous ascites based on experience and prior literature. We propose a multidisciplinary approach to optimize these treatments including the primary surgical teams, pharmacists, and dietitians, with reoperation as a last resort to minimize the morbidity of this challenging complication.

Lymphangiomatosis presented with melena and chylous ascites: A case report.

INTRODUCTION: Lymphangioma, a rare benign tumor of the lymphatic system, is called lymphangiomatosis when it involves >1 organ, which is more rarely complicated with thoracic obstruction, the relationship between them remains unclear. With the development of enteroscopy, clinicians know more about small intestinal lymphangioma and attempt to treat it through enteroscopic injection sclerotherapy(EIS). PATIENT CONCERNS: A 59-year-old male firstly manifested with gastrointestinal bleeding after a gastric perforation, who was diagnosed with lymphangiomatosis by balloon-assisted enteroscopy and abdomen CT showing >1 organ with multiple cysts besides the small intestine. The patient received an EIS, then the melena disappeared. Surprisingly he came back because of refractory ascites confirmed to be chylous by chemical tests 7 months later. DIAGNOSIS: Lymphangiography could not determine the location of lymphatic leakage, Ultrasonography showed stenosis of the left cervical part of the thoracic duct. INTERVENTION: On the condition that medical treatment is ineffective, thoracic duct exploration and lysis of fibrous adhesion were performed. OUTCOMES: Ascites significantly reduced at last. LESSONS: Lymphangiomatosis is the malformation of the lymphatic system involving multiple organs, it has a possibility to be associated with thoracic obstruction. Capsule endoscopy and enteroscopy are effective methods to diagnose small intestinal lymphangioma, and EIS is an effective therapy.

Chylous Ascites: Reassessment of Diagnostic Criteria in Patients With Portal Hypertension.

INTRODUCTION: The triglyceride (TG) threshold for diagnosis of chylous ascites in patients with portal hypertension remains uncertain. METHODS: Retrospective analysis of lipoprotein electrophoresis was conducted in 286 consecutive ascites samples. RESULTS: Ascitic TG ≥ 81 mg/dL is 95.4% sensitive and 94.6% specific for chylous ascites diagnosed by the presence of significant chylomicron population. DISCUSSION: The cutoff for chylous ascites diagnosis should be TG ≥ 81 mg/dL.

Chylous ascites in a case of henoch-schonlein purpura - A case report and literature review.

Chylous ascites is a rare form of ascites characterized by the accumulation of lymph fluid in the peritoneal cavity. Henoch-Schonlein purpura (HSP) is a form of vasculitis usually seen in children affecting small vessels. Gastrointestinal (GI) manifestations of HSP are coming to the forefront as a presenting symptom. The presence of a rash usually succeeds the GI manifestations, making diagnosis difficult and leading to unnecessary surgical interventions. Our case shows a 38-year-old female who presented with an acute abdomen followed by an erythematous rash noticed later on, with radiological investigations suggestive of acute appendicitis. Chylous ascites was found as an incidental finding on diagnostic laparoscopy with a healthy appendix.

Résumé L'ascite chyleuse est une forme rare d'ascite caractérisée par l'accumulation de liquide lymphatique dans la cavité péritonéale. Henoch-Schonlein le purpura (HSP) est une forme de vascularite généralement observée chez les enfants et affectant les petits vaisseaux. Les manifestations gastro-intestinales (GI) de la HSP arrivent au premier plan comme symptôme révélateur. La présence d'une éruption cutanée succède généralement aux manifestations gastro-intestinales, rendant le diagnostic difficile et conduisant à des interventions chirurgicales inutiles. Notre cas montre une femme de 38 ans qui s'est présentée avec un abdomen aigu suivi d'un érythémateux éruption cutanée constatée ultérieurement, avec des investigations radiologiques évocatrices d'une appendicite aiguë. Une ascite chyleuse a été découverte de manière fortuite sur laparoscopie diagnostique avec un appendice sain. Mots-clés: Abdomen aigu, ascite chyleuse, purpura Henoch-Schonlein.

Chylous ascites in the neonate: A narrative review.

Chylous ascites (CA), also called chyloperitoneum, is a rare form of ascites in the neonate. It results from the leakage of lymph into the peritoneal cavity. There are congenital and acquired forms of CA. CA may occur during fetal life, and the prognosis will depend on its volume, gestational age at the onset, and the association with other anomalies. Lymphangiectasia is the most common congenital cause, and acquired forms are mainly traumatic and/or post-operative. This review aims to gather the most current information on CA and addresses important aspects regarding etiology, pathophysiology, clinic, diagnostic tools, and treatment.

How we approach pediatric congenital chylous effusions and ascites.

Congenital lymphatic leak may develop in patients with maldeveloped lymphatics and result in life-threatening fluid and electrolyte imbalance, protein deficiency, and immunodeficiency. Rapid diagnosis and therapy are necessary to prevent these complications; however, the field lacks clinical trials to support standardized diagnostic treatment guidelines. We present our current multidisciplinary approach to the diagnosis and management of congenital lymphatic leak including chylous pleural effusions and ascites. Depending on the rate of lymphatic leak, therapy can range from observation with nutritional modifications to surgical and interventional procedures aimed to reduce lymphatic drainage. Modalities to image central and peripheral lymphatics have advanced considerably. Genetic variants and subsequent targets that drive lymphatic maldevelopment have expanded the repertoire of possible pharmacotherapeutic options.

Refractory ascites after laparoscopic cholecystectomy: a case report.

BACKGROUND: Laparoscopic cholecystectomy is a common surgical option for gallstone disease with minimal trauma and rapid recovery. Ascites is a relatively uncommon complication after laparoscopic cholecystectomy and is more frequently observed in patients with preoperative abnormal liver function. However, patients without underlying liver disease develop refractory ascites after laparoscopic cholecystectomy are rare. We report a case of massive ascites caused by lymphatic injury after laparoscopic cholecystectomy. CASE PRESENTATION: A 63-year-old woman complained of abdominal discomfort and distension at the twelfth day after a laparoscopic cholecystectomy for gallbladder stones. Subsequently, the patient developed spontaneous bacterial peritonitis and a decreased output of urine. Abdominal computed tomography (CT) identified abdominal effusion. The patient received abdominocentesis and the volume of slightly turbid yellow ascites averaged 1500-2000 ml per day. The results of laboratory analysis of ascitic fluid showed the following: serum-ascites albumin-gradient (SAAG), 11-12 g/L; albumin, 11-14 g/L; triglycerides, 0.91 mmol/L. After the diuretic therapy, repeated large-volume paracentesis with albumin supplementation, administration of antibiotics and renal vasodilating medications, the patient's symptoms did not relieve. Lymphoscintigraphy found a small amount of radioactive filling in the abdominal cavity. The patient finally received surgery with detection and ligation of the lymphatic leak. The ascites disappeared and the patient recovered well. CONCLUSIONS: For patients with atypical characteristics of chylous ascites, lymphoscintigraphy could help to localize and qualify the diagnosis. Surgical treatment could be considered when conservative treatment fails.
