ABSTRACT
BACKGROUND@#Postoperative chylous ascites is an infrequent condition after colorectal surgery and is easily treatable. However, its effect on the long-term oncological prognosis is not well established. This study aimed to investigate the short-term and long-term impact of chylous ascites treated with neoadjuvant therapy followed by rectal cancer surgery and to evaluate the incidence of chylous ascites after different surgical approaches.@*METHODS@#A total of 898 locally advanced rectal cancer patients treated with neoadjuvant chemoradiotherapy followed by surgery between January 2010 and December 2018 were included. The clinicopathological data and outcomes of the patients with chylous ascites were compared with those of the patients without chylous ascites. The primary endpoint was recurrence-free survival (RFS). To balance baseline confounders between groups, propensity score matching (PSM) was performed for each patient with a logistic regression model.@*RESULTS@#Chylous ascites was detected in 3.8% (34/898) of the patients. The incidence of chylous ascites was highest after robotic surgery (6.9%, 6/86), followed by laparoscopic surgery (4.2%, 26/618) and open surgery (1.0%, 2/192, P = 0.021). The patients with chylous ascites had a significantly higher number of lymph nodes harvested (15.6 vs. 12.8, P = 0.009) and a 3-day longer postoperative hospital stay (P = 0.017). The 5-year RFS rate was 64.5% in the chylous ascites group, which was significantly lower than the rate in the no chylous ascites group (79.9%; P = 0.007). The results remained unchanged after PSM was performed. The chylous ascites group showed a nonsignificant trend towards a higher peritoneal metastasis risk (5.9% vs. 1.6%, P = 0.120). Univariate analysis and multivariate analysis confirmed chylous ascites (hazard ratio= 3.038, P < 0.001) as an independent negative prognostic factor for RFS.@*CONCLUSIONS@#Considering the higher incidence of chylous ascites after laparoscopic and robotic surgery and its adverse prognosis, we recommend sufficient coagulation of the lymphatic tissue near the vessel origins, especially during minimally invasive surgery.

Abstract Chylous ascites is the pathologic accumulation of chylous fluid in the peritoneal cavity, caused by lymphomas, metastatic malignancies, and abdominal surgeries, rarely due to surgical trauma of the cisterna chyli or its major branches. A 24-year-old man with history of Marfan syndrome presented to our hospital with abdominal distention, abdominal pain, fluid in the incision region, and weakness. He had underwent an elective open aneurysm repair surgery nine days before for thoracoabdominal aortic aneurysm. Computed tomography revealed massive fluid collection in the abdominal cavity, which was drained surgically. He was diagnosed with chylous ascites and was discharged after conservative treatment.

Chylous Ascites (CA) and chylothorax (CTx) are associated with obstruction, disruption or insufficiency of the lymphatic system. We report a 68-year-old male, with a history of alcoholic cirrhosis, who had recurrent events of CTx and CA. After a complete study, no other etiologies other than portal hypertension were found. Therapy with diuretics, nothing per mouth, parenteral feeding plus octreotide did not relieve symptoms. A transjugular intrahepatic portosystemic shunt (TIPS) was successfully placed and pleural effusion subsided. This case shows that CA and CTx can be caused by portal hypertension and they may subside employing a multimodal management strategy.

INTRODUCCIÓN: La ascitis quilosa es la presencia de líquido linfático en la cavidad peritoneal. Como consecuencia de una cirugía abdominal es muy infrecuente, encontrando 5 casos previos en la literatura revisada tras colecistectomía. OBJETIVO: Presentar un caso clínico de ascitis quilosa poscolecistectomía, su manejo y una revisión de la literatura. MATERIALES Y MÉTODOS: Varón de 77 años, quiloperitoneo 21 días después de realización de colecistectomía programada por colecistitis aguda. Resultados: Se realiza drenaje percutáneo con débito de 5 L en 24 horas, se inicia octreótido subcutáneo y nutrición parenteral total. Al tercer día disminuye el débito por el drenaje, por lo que se inicia dieta rica en triglicéridos de cadena media con buena evolución posterior. De los 5 casos previos tras colecistectomía, el 60% se resolvió con tratamiento conservador, un paciente precisó reintervención y otro colocación de un shunt portosistémico intrahepático trasnyugular (TIPSS). CONCLUSIÓN: La ascitis quilosa es una complicación postquirúrgica infrecuente, encontrando solo 5 casos previos tras colecistectomía. Inicialmente el manejo debe ser conservador, en caso de persistencia se deben valorar otras medidas.
INTRODUCTION: Chylous ascites is defined as the presence of lymph fluid in the peritoneal cavity. It is a rare complication after abdominal surgery; only 5 previously reported cases were found after cholecystectomy. Aim: Present a case report and a literature review. MATERIALS AND METHOD: Case report of a 77 year old male who underwent an elective cholecystectomy due to acute cholecystitis. Chyloperitoneum showed up 21 days after surgery. RESULTS: We performed a percutaneous drainage and 5 L of fluid were removed in 24 hours. We started treatment with subcutaneous Octreotide and total parenteral nutrition. After 3 days drain output decreased and we started a medium-chain triglycerides diet with good progress. The outcome of 60% of the 5 previous case reports of chyloperitoneum after cholecystitis, were successful with conservative management, surgical intervention was needed in one patient and a transjugular intrahepatic portosystemic shunt (TIPSS) was placed in another patient. CONCLUSION: Chylous ascites is a rare complication after surgery, there are only 5 previously case reports after cholecystectomy. Conservative management has to be the first option and in case of persistence another therapy has to be considered.

Chylous ascites is a peritoneal collection with milky appearance, rich in triglycerides produced by the presence of thoracic or intestinal lymph in the abdominal cavity. The increasing number of surgical interventions has meant an increase of this disease in the last time. We present the case of a 39-yearsold woman with a history of a retroperitoneal cystic lesion in the abdominal ultrasound, which was a finding, and was followed up for 5 years. In the last control abdominal ultrasound showed an accelerated growth, the study was complemented with a Magnetic Resonance Imaging of the abdomen showed a retroperitoneal cystic lesion, 7 cm larger diameter in contact with aorta, left ureter and lower pole of the left kidney, suspecting malignancy, reason why its surgical resection was decided. It evolved after the surgical intervention with progressive increase of the abdominal perimeter, diffuse pain and early satiety, performing abdominal ultrasound showing a liver of normal structure with moderate ascites. The diagnostic paracentesis gave out 1,000 mL of milky-white liquid with triglycerides of 1,287 mg/dL. The diagnosis of chylous ascites was proposed, secondary to thoracic duct injury and it was managed with a diet with low intake of saturated, polyunsaturated and monounsaturated fats, with medium chain triglycerides with favorable results. The pathophysiology, etiology, nutritional and non-nutritional management of chylous ascites are discussed.
La ascitis quilosa es una colección peritoneal con apariencia lechosa, rica en triglicéridos producido por la presencia de linfa torácica o intestinal en la cavidad abdominal. El creciente número de intervenciones quirúrgicas ha significado un aumento de esta patología en el último tiempo. Se presenta el caso de una mujer de 39 años, con historia de una lesión retroperitoneal quística en la ecotomografía abdominal, que fue un hallazgo, realizándose seguimiento por 5 años. En la última ecotomografía de control presentó crecimiento acelerado por lo que se complementa estudio con una Resonancia Nuclear Magnética de abdomen que muestro lesión quística retroperitoneal de 7 cm de diámetro mayor en contacto con aorta, uréter izquierdo y polo inferior del riñón izquierdo, sospechándose malignidad, por lo que se decide su resección. Evolucionó posterior a la intervención quirúrgica con aumento progresivo del perímetro abdominal, dolor difuso y saciedad precoz, realizándose ecotomografía abdominal que muestra un hígado de estructura normal con ascitis moderada. La paracentesis diagnóstica dio salida a 1.000 mL de líquido blanquecino de aspecto lechoso con triglicéridos de 1.287 mg/dL. Se planteó el diagnóstico de ascitis quilosa, secundario a lesión del conducto torácico y se manejó con dieta con bajo aporte en grasas saturadas, poliinsaturadas y monoinsaturadas, con aporte de triglicéridos de cadena media con resultados favorables. Se discuten la fisiopatología, etiología, manejo nutricional y no nutricional de la ascitis quilosa.

Background: Chylous ascites is defined as the presence of thoracic or intestinal lymph in the abdominal cavity. Its association with acute pancreatitis is uncommon. Aim: To report three cases of chilous ascites related with acute pancreatitis. Material and Methods: Review of medical records of three patients with chylous ascites associated with acute pancreatitis. Results: We report three patients with chylous ascites out of 2,188 admissions for acute pancreatitis (0.13 percent). A 39 years old male with a pancreatic pseudocyst. During surgery, chylous ascites was found. He was successfully treated with octreotide and spironolactone. A 71 years male operated for an acute cholecystitis and a perivesicular abscess. Three days after surgery, a chylous fluid appears in the abdominal drainage, which disappears spontaneously. A 73 years old female operated for an acute pancreatitis. During surgery a chylous ascites is found. The patient died four days after surgery. Conclusions: Chylous ascites associated with pancreatitis is uncommon and octreotide may have a therapeutic role for it.
Introducción: La ascitis quilosa (AQ) se define como la presencia de linfa de origen torácico o intestinal en la cavidad abdominal. Asociada a Pancreatitis Aguda (PA), sólo se han documentado 12 casos hasta 2013. El objetivo de este trabajo es presentar tres nuevos casos y realizar una revisión de la presentación, clínica, diagnóstico y tratamiento de esta entidad. Material y Métodos: Se recogen los datos clínicos y evolutivos de tres pacientes con AQ secundaria a pancreatitis aguda (AQPA); esta se ha definido como la presencia de linfa en cavidad abdominal en un paciente con episodio de pancreatitis aguda reciente y sin antecedente traumático, infeccioso, neoplásico o quirúrgico que pudiera ser el responsable de la misma. Se han recogido igualmente todos los casos documentados hasta 2013. Resultados: En los últimos 10 años han sido ingresados 2.188 pacientes por PA entre los cuales, se han diagnosticado 3 casos de AQPA (0,13 por ciento), dos hombres y una mujer, con PA de origen biliar. El diagnóstico ha sido "de visu" intra o postoperatorio. El débito inicial fue de 3.000, 300 y 1.500 cc. El tratamiento ha contado con octeótrido de entrada en todos los casos. En la revisión bibliográfica la AQPA ha sido diagnosticada también "de visu" y los pacientes se han resuelto con tratamiento conservador, tardando una media de 27,7 días si se utiliza octeótrido frente a 46,5 días si no se le ha prescrito. Conclusiones: La AQ asociada a PA sigue siendo infrecuente, su diagnóstico es "de visu" y se resuelve con tratamiento conservador, siendo el octeótrido un fármaco de primera línea.

To study and analyze the causes of chylous leakage after pancreaticoduodenectomy. We retrospectively analyzed 381 patients who underwent pancreaticoduodenectomy [including pylorus-preserving pancreaticoduodenectomy] in Shanghai Chang Hai Hospital Affiliated to the Second Military Medical University, Shanghai, China between January 2010 and December 2012. We also studied the relationship between postoperative chylous leakage and age, gender, surgical approach, and the tumor nature. The chylous leak was placed in 23 patients and the incidence of chylous leakage in patients was 0.6%. There was no significant difference in gender, age and tumor pathological pattern between the chylous leakage group and non-chylous leakage group. The incidence of chylous leakage in patients with N1 grade cancer was significantly higher than that in patients with N0 grade cancer [p=0.001]. The incidence of chylous leakage in patients suffering R0 resection was significantly higher than that in patients suffering non-R0 resection [p=0.008]. All patients were successfully treated conservatively. The incidence of chylous leakage was 0.6% and the chylous leakage was closely linked with the tumor's grade malignancy and the range of radical resection

To evaluate chylous drainage and its management in donor nephrectomy patients. Retrospective study. Institute of Post Graduate Medical Education and Research [IPGME and R], Kolkata, and Medica Superspeciality Hospital, Kolkata, Kolkata, India. Donor nephrectomy patients [open or laparoscopy procedure]. The first case of chylous drainage which occurred after open donor nephrectomy was treated with conservative management for a prolonged period after browsing through literature. Later three cases which occurred after laparoscopic donor nephrectomy, were also managed conservatively. Incidence and management of chylous ascites or drainage after open or laparoscopic donor nephrectomy. In our institute, only four donor nephrectomy patients developed chylous drainage. Three were laparoscopic surgeries using the transperitoneal approach whereas one case was done using open retroperitoneal approach. Chylous drainage and its management are discussed. Overall, our cases showed that chylous drainage can develop in laparoscopic transperitoneal procedures as well as in open retroperitoneal surgery, and that surgical dissection in the retroperitoneal area or the renal hilum is the most important risk factor for this complication. All our cases were well-treated only by conservative management and it has proven to be the main first line management for this condition

To assess possible factors that may play a role in the etiology of chylous ascites formation, to determine the management of each type according to its causation, and to compare between the results of conservative and operative management. This is a prospective study conducted from 1990 to 2004 in the surgical department of Erbil, Iraq. A group of 46 patients with chylous ascites were subdivided into five subgroups according to the etiological factors. The initial assessment included: age, sex, history of trauma and previous surgery, time between the trauma, if it was present, and the appearance of chylous ascites, and aspiration of ascetic fluid for chemical and bacteriological analysis. Further assessment included the use of ultrasonography, computerized axial tomography, and Magnetic resonance imaging [MRI]. There were 12 female and 34 male patients. Their ages ranged form one year to 63 years [mean age 37 years]. There was abdominal distention resulting from the accumulation of chyle in the peritoneal cavity in all five subgroups of patients. A definitive diagnosis was made by paracentesis and laparotomy. Thirty-eight patients [82.6%] underwent explorative laparotomy. The surgical success rate for trauma patients was about 93.7%, while it was very poor for malignant cases. The surgical technique in this study with the best results was overswing with omental patch. The results indicate that patients with chylous ascites caused by trauma to the abdomen who undergo surgery may have a success rate up to about 93.7% using omental patches, especially if preoperative resuscitation is done. The outcome of patients with malignant chylous ascites, however, was very poor. Conservative treatment was not satisfactory in any of these cases

Efusão quilosa pleural ou quilotórax significa acúmulo quiloso no espaço pleural, geralmente como ruptura secundária dos ductos linfáticos torácicos, que pode ser promovida por vários estímulos, desde trauma, doenças malignas até causas idiopáticas. É definido como uma efusão de linfa na cavidade pleural, podendo ter origem no tórax ou na cavidade abdominal, ou em ambos. É de aspecto leitoso, inodoro, branco, de pH alcalino com gravidade específica acima de 1012, bacteriostático, não irritativo à pleura. É opalescente, formado quando triglicérides de cadeia longa da dieta são transformados em quilomícrons de baixa densidade lipoprotéica secretados no intestino. O quilo é transportado através do ducto torácico e drenado na veia subclávia esquerda. O diagnóstico é baseado em análise clínica da efusão pleural contendo quilomícrons e níveis de triglicérides maior que 110 mg/dL como indicativo praticamente certo de efusão pleural quilosa. A conduta depende da causa e das circunstâncias individuais. Um relato de quilotórax bilateral e quiloascite espontâneos é apresentado com ótima evolução através de tratamento conservador com a utilização de dieta enteral oligomérica, rica em aminoácidos, com glutamina e mínima oferta de triglicérides de cadeia média e octeotride
Chylous pleural effusion or chylothorax means chyle accumulation in the pleural space generally as a secondary disruption of thoracic lymphatics, that can be promoted by various stimulants, since trauma, malignancies, to idiopathic causes. Is defined as an effusion of limphin pleural cavity. Chyle may have its origin in the thorax or in the abdomen, or both. Is a milky, white, alkaline pH with a specific gravity above 1012, bacteriostatic and nonirritating to thepleural space, opalescent fluid formed when long-chain triglycerides in the diet are transformed into chylomicrons and very-low-density lipoproteins and secreted into intestinal lacteals. The chyle is transported through the thoracic duct and drained into the left subclavian vein. Diagnosis is based on a chemical analysis of the pleural effusion presenting chylomicrons, pleural triglyceride with levels greater than 110 mg/dL being nearly always indicative of a chylous pleural effusion. Management depends on the underlying cause and the individual circumstances. A case report of spontaneous chylothorax and chyloascitis is presented successfullytreated by conservative means, using oligomeric enteral feeding, rich in amino acids with minimum quantity of medium-chain-triglycerides, glutamine, and octeotride

La linfadenectomía lumboaórtica post quimioterapia es el único método que ofrece posibilidades de etapificación y curación en masas residuales. Entre mayo de 1993 y agosto de 2001 se realizaron 104 linfadenectomía lumboaórtica en pacientes con cáncer de testículo, de ellos 11 (10,57 por ciento) fueron por masas retroperitoneales post quimioterapia. El promedio de edad fue 24,36 años. El estadio clínico fue IIa 4 (36,36 por ciento), IIb en 5 (45,45 por ciento), y IIc en 2 (18,18 por ciento). El tiempo operatorio promedio fue de 124 minutos (100-170 minutos), el sangrado promedio fue de 75 cc (0-300 cc), el tiempo de hospitalización en horas fue de 52,8 (24-144 horas), el tamaño promedio de las masas resecadas fue de 3,7 cm (2-8 cm). Hubo 1 conversión. La única complicación post operatoria correspondió a una Ascitis Quilosa masiva resuelta laparoscópicamente. El seguimiento promedio fue de 8, 5 meses. En nuestra experiencia inicial podemos ver una disminución de los tiempos operatorios y de hospitalización comparadas con lo descrito en la literatura. Consideramos que la cirugía laparoscópica de rescate en masas retroperitoneales post quimioterapia es un procedimiento técnicamente posible. Es importante considerar las limitaciones que determinan el tamaño de la masa y el hecho de que la cirugía laparoscópica es, hasta ahora, un procedimiento unilateral. La linfadenectomía lumboaórtica laparoscópica post quimioterapia tiene indicaciones limitadas
