Examination of the abdomen revealed tenderness in the periumblical area with shifting dullness. Serum pancreatic amylase was 29 IU/L and lipase 44 IU/L, triglyceride 36.28 mmol/L. Ultrasound showed ascites. CT of the abdomen with contrast showed inflammatory changes surrounding the pancreas consistent with acute pancreatitis. Ultrasound (US) guided abdomen paracentesis yielded a milky fluid with high triglyceride content consistent with chylous ascites. The patient was kept fasting and intravenous fluid hydration was provided. Meperidine was administered for pain relief. On the following days the patient’s condition improved and he was gradually restarted on a low-fat diet, and fat lowering agent (gemfibrozil) was begun, 600 mg twice a day. On d 14, abdomen US was repeated and showed fluid free peritoneal cavity. The patient was discharged after 18 d of hospitalization with 600 mg gemfibrozil twice a day. At the time of discharge, the fasting triglyceride was 4.2 mmol/L. After four weeks the patient was seen in the clinic, he was well.展开更多

However, no cases of P. mameffei infection with chylous ascites have been reported thus far. In this re- port, we describe the first case of acquired immune de- ficiency syndrome (AIDS) which has been complicated by a P. marneffei infection causing chylous ascites. We describe the details of the case, with an emphasis on treatment regimen. This patient was treated with am- photericin B for 3 mo, while receiving concomitant ther- apy with an efavirenz-containing antiretroviral regimen, but cultures in ascitic fluid were persistently positive for P. marneffei. The infection resolved after treatment with high-dose voriconazole (400 mg every 12 h) for 3 too. R marneffei should be considered in the differential di- agnosis of chylous ascites in human immunodeficiency virus patients. High-dose voriconazole is an effective, well-tolerated and convenient option for the treatment of systemic infections with R marneffei in AIDS patients on an efavirenz-containing antiretroviral regimen.展开更多

The majority of cases do not develop CA,possibly due to patency of the proximal thoracic duct and good collaterals. CA may be due to a consequence of occult obstruction of the proximal thoracic duct by malignant infiltration or tumor embolus. This study was to report the incidence of CA and its outcomes of management. METHODS:A retrospective search of our liver database was performed using the 'pancreatico-duodenectomy','chylous ascites' from January 2000 to December 2005. The medical records of CA patients and their management and outcome were reviewed. RESULTS:In 138 patients who had undergone PD in our centre for pancreatic malignancy,3 were identified with CA and managed by abdominal paracentesis. CA resolved in 2 patients with low fat medium chain triglyceride diet alone and 1 patient had total parenteral nutrition(TPN) for persistent CA. Resolution of CA occurred in these 3 patients at a median follow-up of 4 weeks(range 4-12 weeks). Histologically,resected specimen confirmed pancreatic adenocarcinoma in all the patients. Two patients developed loco-regional recurrences at a median follow up of 8 months(range 6-10 months). And the other was currently disease free at a 10-month follow up. CONCLUSIONS:CA as an uncommon postoperative complication requires frequent paracentesis,prolonged hospital stay,and delayed adjuvant chemotherapy. CA istreated with low fat medium chain triglyceride diet or occasionally TPN is required.展开更多

An 85-year-old female patient with anterior vaginal prolapse 1V (AVP IV), vaginal vault proplapse IV and posterior vaginal prolapse IV (PVP IV), developed Chylous ascites 2 weeks after she received whole pelvis suspension, The cause of chylous ascites in the present case was not associated with malignant tumor, hepatic cirrhosis, or inflammation. Therefore, surgical trauma may be considered the cause of disorder. X-ray lymphangioadenography should be performed to draw a final conclusion.展开更多

Here we present the case of a 28-year old pregnant woman, in whom an aggressive mesenteric fibromatosis with chylous ascites was detected, involving the jejunum, superior rnesenteric artery (SMA) and superior rnesenteric vein (SMV) and pancreas. One year after a successful surgical excision, the patient had no signs of recurrence. The authors report the case for its rarity and emphasize on combining clinicopathological, radiological and immunohistochemistry analysis for management of the disease.展开更多

Primary conservative therapy involved total parenteral nutrition, continuous low-pressure drainage, somatostatin, and a lowfat diet. Drainage tube(DT) clamping has been presented as a potential alternative conservative treatment for GC patients with CA.AIM To propose novel conservative treatment strategies for CA following GC surgery.METHODS The data of patients with CA after GC surgery performed at the Fudan University Shanghai Cancer Center between 2006 and 2021 were evaluated retrospectively.RESULTS 53 patients underwent surgery for GC and exhibited postoperative CA during the study period. Postoperative hospitalization and time of DT removal showed a significant positive association(R~2 = 0.979, P < 0.001). We further observed that delayed DT removal significantly extended the total and postoperative hospitalization, antibiotic usage duration, and hospitalization cost(postoperative hospitalization: 25.8 d vs 15.5 d, P < 0.001;total hospitalization: 33.2 d vs 24.7 d, P < 0.01;antibiotic usage duration: 10.8 d vs 6.2 d, P < 0.01;hospitalization cost: ¥9.2 × 104vs ¥6.5 × 104, P < 0.01). Multivariate analysis demonstrated that postoperative infection and antibiotic usage were independent factors for delayed DT removal.Furthermore, DT removal times were shorter in seven patients who underwent DT clamping(clamped DT vs normal group, 11.8 d vs 13.6 d, P = 0.047;clamped DT vs delayed group, 13.6 d vs 27.4 d, P < 0.001). In addition, our results indicated that removal of the DT may be possible after three consecutive days of drainage volumes less than 300 mL in GC patients with CA.CONCLUSION Infection and antibiotic usage were vital independent factors that influenced delayed DT removal in patients with CA. Appropriate standards for DT removal can significantly reduce the duration of hospitalization. Furthermore, DT clamping might be a recommended option for conservative treatment of postoperative CA.展开更多

Methods: We identified the cases of 913 consecutive patients who underwenturgery for colorectal cancerat our University Hospital between January 2005and December2016. We divided the patients into thosewith and those without chylous ascites and compared the two groups by age, gender, body mass index, tumor location, T, N factor, stage, operation time, intra-operative bleeding, and duration of postoperative hospital stay. Results: Chylous ascites developed in 8 of the 913 patients (0.8%). Neither age, sex, tumor location, and body mass indexnor number of lymph nodeswereassociated with postoperative chylous ascites. Ascites occurred significantly less frequently in the early stage of colorectal cancer than in the late stage (p = 0.04). There was no significant difference between the groups in operative factors, including operation time and blood loss. Postoperative hospital stays were longer in patients with chylous ascites (20.5 days) than in those without (11 days) (p = 0.02). Conclusions: Late stage was one of the risk factors for chylous ascites in the present study. Other risks, such as tumor location and blood loss,will vary from institution to institution.展开更多

Now th...Postoperative chylous ascites, which is caused by the disruption of lymphatic channels and persistent lymphatic leakage, was a rare complication in the urologic field before laparoscopic surgery was introduced. Now that laparoscopic urologic surgery, especially laparoscopic nephrectomy, is widely performed, chylous ascites as a complication of laparoscopic renal surgery has been reported more frequently. With these accumulated experiences and data comes knowledge about the proper diagnosis and management of chylous ascites, although there is still some debate regarding the correct protocol for diagnosis and management. Therefore, we performed a systematic review of the current literature regarding the etiology, incidence, diagnosis, management, and prognosis of chylous ascites after laparoscopic renal surgery, as well as strategies used to prevent it, and discuss current perspectives on overcoming this complication in the laparoscopic age.展开更多

It is a difficult ...Chylous ascites, an uncommon disease usually caused by obstruction or rupture of the peritoneal or retroperitoneal lymphatic glands, is defined as the accumulation of chyle in the peritoneal cavity. It is a difficult management problem due to the serious mechanical, nutritional, and immunological consequences of the constant loss of protein and lymphocytes. Most investigators believe that the incidence of chylous ascites is increasing because of more aggressive thoracic and retroperitoneal surgery and also because of the prolonged survival of patients with cancer. Although the incidence of chylous ascites has increased in recent years, treatment remains unsatisfactory. The standard conservative treatments include paracentesis, a medium chain triglyceride (MCT) based diet, total parenteral nutrition (TPN), and recently recommended somatostatin, are preferable in most cases, but usually need several weeks to cure chyloperitonum. Open or laparoscopic ligation of ruptured lymph ducts, a commonly used procedure for persistent chylous ascites, may fail in patients without visible chylous leak. Fibrin glue, a widely used approach to treat various kinds of fistulae, has recently been reported to seal chylous leak during operation. Here we present two cases of chylous ascites who were successfully treated with fibrin glue in different settings.展开更多

文摘We report a case of Chylous ascites after whole pelvis suspension and to discuss the possible reasons. An 85-year-old female patient with anterior vaginal prolapse 1V (AVP IV), vaginal vault proplapse IV and posterior vaginal prolapse IV (PVP IV), developed Chylous ascites 2 weeks after she received whole pelvis suspension, The cause of chylous ascites in the present case was not associated with malignant tumor, hepatic cirrhosis, or inflammation. Therefore, surgical trauma may be considered the cause of disorder. X-ray lymphangioadenography should be performed to draw a final conclusion.

Here we present the case of a 28-year old pregnant woman, in whom an aggressive mesenteric fibromatosis with chylous ascites was detected, involving the jejunum, superior rnesenteric artery (SMA) and superior rnesenteric vein (SMV) and pancreas. One year after a successful surgical excision, the patient had no signs of recurrence. The authors report the case for its rarity and emphasize on combining clinicopathological, radiological and immunohistochemistry analysis for management of the disease.

文摘BACKGROUND Chylous ascites(CA) presents a challenge as a relatively common postoperative complication in gastric cancer(GC). Primary conservative therapy involved total parenteral nutrition, continuous low-pressure drainage, somatostatin, and a lowfat diet. Drainage tube(DT) clamping has been presented as a potential alternative conservative treatment for GC patients with CA.AIM To propose novel conservative treatment strategies for CA following GC surgery.METHODS The data of patients with CA after GC surgery performed at the Fudan University Shanghai Cancer Center between 2006 and 2021 were evaluated retrospectively.RESULTS 53 patients underwent surgery for GC and exhibited postoperative CA during the study period. Postoperative hospitalization and time of DT removal showed a significant positive association(R~2 = 0.979, P < 0.001). We further observed that delayed DT removal significantly extended the total and postoperative hospitalization, antibiotic usage duration, and hospitalization cost(postoperative hospitalization: 25.8 d vs 15.5 d, P < 0.001;total hospitalization: 33.2 d vs 24.7 d, P < 0.01;antibiotic usage duration: 10.8 d vs 6.2 d, P < 0.01;hospitalization cost: ¥9.2 × 104vs ¥6.5 × 104, P < 0.01). Multivariate analysis demonstrated that postoperative infection and antibiotic usage were independent factors for delayed DT removal.Furthermore, DT removal times were shorter in seven patients who underwent DT clamping(clamped DT vs normal group, 11.8 d vs 13.6 d, P = 0.047;clamped DT vs delayed group, 13.6 d vs 27.4 d, P < 0.001). In addition, our results indicated that removal of the DT may be possible after three consecutive days of drainage volumes less than 300 mL in GC patients with CA.CONCLUSION Infection and antibiotic usage were vital independent factors that influenced delayed DT removal in patients with CA. Appropriate standards for DT removal can significantly reduce the duration of hospitalization. Furthermore, DT clamping might be a recommended option for conservative treatment of postoperative CA.
文摘Filariasis is a common health problem in tropical and subtropical regions including India. It commonly presents with lymphatic involvement in form of nonpitting pedal edema, chylous ascites, chyluria,hydrocele and lymphocele. Detection of microfilaria in ascitic fluid is an extremely uncommon finding. We present a case of non chylous ascites where microfilaria were detected in the ascitic fluid.
文摘Objectives: To investigate the epidemiology and risk factors of chylous ascites. Methods: We identified the cases of 913 consecutive patients who underwenturgery for colorectal cancerat our University Hospital between January 2005and December2016. We divided the patients into thosewith and those without chylous ascites and compared the two groups by age, gender, body mass index, tumor location, T, N factor, stage, operation time, intra-operative bleeding, and duration of postoperative hospital stay. Results: Chylous ascites developed in 8 of the 913 patients (0.8%). Neither age, sex, tumor location, and body mass indexnor number of lymph nodeswereassociated with postoperative chylous ascites. Ascites occurred significantly less frequently in the early stage of colorectal cancer than in the late stage (p = 0.04). There was no significant difference between the groups in operative factors, including operation time and blood loss. Postoperative hospital stays were longer in patients with chylous ascites (20.5 days) than in those without (11 days) (p = 0.02). Conclusions: Late stage was one of the risk factors for chylous ascites in the present study. Other risks, such as tumor location and blood loss,will vary from institution to institution.

文摘BACKGROUND Chylous ascites following right colectomy has a high incidence which is a critical challenge.At present,there are few studies on the factors affecting chylous ascites after right colectomy and especially after D3 Lymphadenectomy.A predictive model for chylous ascites has not yet been established.Therefore,we created the first nomogram to predict the incidence of chylous ascites after right hemicolectomy.AIM To analyze the risk factors for chylous ascites after right colectomy and establish a nomogram to predict the incidence of chylous ascites.METHODS We retrospectively collected patients who underwent right hemicolectomy between January 2012 and May 2021 and were pathologically diagnosed with cancer.Multivariate logistic regression was used to analyze the influencing factors of chylous ascites and a nomogram was established.The predictive ability was assessed by the area under the receiver operating characteristic(ROC)curve.RESULTS Operative time,the type of operation(standard or extended),the number of lymph nodes retrieved,and somatostatin administration were considered important risk factors.Multivariate logistic regression and nomograms can be used to accurately predict whether chylous ascites occurs.The area under the ROC curve of the model is 0.770.The C-statistic of this model is 0.770 which indicates that it has a relatively moderate ability to predict the risk of chylous ascites.CONCLUSION We found a novel set of risk factors,created a nomogram,and validated it.The nomogram had a relatively accurate forecasting ability for chylous ascites after right hemicolectomy and can be used as a reference for risk assessment of chylous ascites and whether to prevent it after surgery.
文摘Chylous ascites, a rare clinical condition resulting from the disruption of the abdominal lymphatic system, usually diagnosed by paracentesis when the patients suffer ascites as primary symptom. The conditions, in which chylous ascites arise after chemotherapy of solid tumor, are rarely reported. In this paper we present a quite rare case of chylous ascites arising after chemotherapy of gastric signet ring cell carcinoma.
文摘Postoperative chylous ascites, which is caused by the disruption of lymphatic channels and persistent lymphatic leakage, was a rare complication in the urologic field before laparoscopic surgery was introduced. Now that laparoscopic urologic surgery, especially laparoscopic nephrectomy, is widely performed, chylous ascites as a complication of laparoscopic renal surgery has been reported more frequently. With these accumulated experiences and data comes knowledge about the proper diagnosis and management of chylous ascites, although there is still some debate regarding the correct protocol for diagnosis and management. Therefore, we performed a systematic review of the current literature regarding the etiology, incidence, diagnosis, management, and prognosis of chylous ascites after laparoscopic renal surgery, as well as strategies used to prevent it, and discuss current perspectives on overcoming this complication in the laparoscopic age.
文摘BACKGROUND The lymphatic system is crucial in maintaining the body fluid homeostasis.A dysfunctional lymphatic system may contribute to the refractoriness of ascites and edema in cirrhosis patients.Therefore,assessment of lymphatic dysfunction in cirrhosis patients with refractory ascites(RA)can be crucial as it would call for using different strategies for fluid mobilization.AIM To assessing the magnitude,spectrum,and clinical associations of lymphatic dysfunction in liver cirrhosis patients with RA.METHODS This observational study included 155 consecutive cirrhosis patients with RA.The presence of clinical signs of lymphedema,such as peau d’orange appearance and positive Stemmer sign,intestinal lymphangiectasia(IL)on duodenal biopsy seen as dilated vessels in the lamina propria with strong D2-40 immunohistochemistry,and chylous ascites were used to diagnose the overt lymphatic dysfunctions.RESULTS A total of 69(44.5%)patients out of 155 had evidence of lymphatic dysfunction.Peripheral lymphedema,found in 52(33.5%)patients,was the most common manifestation,followed by IL in 42(27.0%)patients,and chylous ascites in 2(1.9%)patients.Compared to patients without lymphedema,those with lymphedema had higher mean age,median model for end-stage liver disease scores,mean body mass index,mean ascitic fluid triglyceride levels,and proportion of patients with hypoproteinemia(serum total protein<5 g/dL)and lymphocytopenia(<15%of total leukocyte count).Patients with IL also had a higher prevalence of lymphocytopenia and hypoproteinemia(28.6%vs.9.1%,P=0.004).Seven(13%)patients with lymphedema had lower limb cellulitis compared to none in those without it.On multivariate regression analysis,factors independently associated with lymphatic dysfunction included obesity[odds ratio(OR):4.2,95%confidence intervals(95%CI):1.1–15.2,P=0.027],lymphocytopenia[OR:6.2,95%CI:2.9–13.2,P<0.001],and hypoproteinemia[OR:3.7,95%CI:1.5–8.82,P=0.003].CONCLUSION Lymphatic dysfunction is common in cirrhosis patients with RA.Significant indicators of its presence include hypoproteinemia and lymphocytopenia,which are likely due to the loss of lymphatic fluid from the circulation.Future efforts to mobilize fluid in these patients should focus on methods to improve lymphatic drainage.

文摘Background:Chylous ascites(CA),an emulsion rich in triglycerides,is a rare type of ascites,especially after cardiac surgery.Also,there are few reports of the occurrence of CA after mitral valve replacement,aortic valve replacement,tricuspid valvuloplasty,and coronary artery bypass grafting.Case presentation:We report the case of a 53-year-old man who underwent surgery for a diagnosis of mitral incompetence,aortic incompetence,tricuspid incompetence,and coronary atherosclerotic heart disease.Fifteen days after surgery,3000 mL of milky-yellow ascites appeared in the abdominal cavity,diagnosed as CA by laboratory examination.The ascites gradually disappeared after being drained,and the patients improved.The curative was objective,but the exact cause is not clear.Conclusion:Although CA is rare,it may occur during the surgical intervention in cardiac surgery.
文摘We report a case of acute chylous ascites formation presenting as peritonitis(acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse.The development of chylous ascites is usually a chronic process mostly involving malignancy,trauma or surgery,and symptoms arise as a result of progressive abdominal distention.However,when accumulation of "chyle" occurs rapidly,the patient may present with signs of peritonitis.Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation,appendicitis or visceral ischemia.Less than 100 cases of acute chylous peritonitis have been reported.Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days(or even weeks) after the onset of symptoms of pancreatitis.This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis,and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis.The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer,since,due to hypertriglyceridemia,serum amylase values appeared within the normal range.Moreover,abdominal computed tomography imaging was not diagnostic for pancreatitis.Following abdominal lavage and drainage,the patient was successfully treated with total parenteral nutrition and octreotide.
文摘Chylous ascites, an uncommon disease usually caused by obstruction or rupture of the peritoneal or retroperitoneal lymphatic glands, is defined as the accumulation of chyle in the peritoneal cavity. It is a difficult management problem due to the serious mechanical, nutritional, and immunological consequences of the constant loss of protein and lymphocytes. Most investigators believe that the incidence of chylous ascites is increasing because of more aggressive thoracic and retroperitoneal surgery and also because of the prolonged survival of patients with cancer. Although the incidence of chylous ascites has increased in recent years, treatment remains unsatisfactory. The standard conservative treatments include paracentesis, a medium chain triglyceride (MCT) based diet, total parenteral nutrition (TPN), and recently recommended somatostatin, are preferable in most cases, but usually need several weeks to cure chyloperitonum. Open or laparoscopic ligation of ruptured lymph ducts, a commonly used procedure for persistent chylous ascites, may fail in patients without visible chylous leak. Fibrin glue, a widely used approach to treat various kinds of fistulae, has recently been reported to seal chylous leak during operation. Here we present two cases of chylous ascites who were successfully treated with fibrin glue in different settings.

文摘Chylous ascites(CA)is a rare form of ascites that results from the leakage of lipid-rich lymph into the peritoneal cavity.This usually occurs due to trauma and rupture of the lymphatics or increased peritoneal lymphatic pressure secondary to obstruction.The underlying etiologies for CA have been classified as traumatic,congenital,infectious,neoplastic,postoperative,cirrhotic or cardiogenic.Since malignancy and cirrhosis account for about two-thirds of all the cases of CA in Western countries,in this article we have attempted to reclassify CA based on portal and non-portal etiologies.The diagnosis of CA is based on the distinct characteristic of the ascitic fluid which includes a milky appearance and a triglyceride level of>200 mg/dL.The management consists of identifying and treating the underlying disease process,dietary modification,and diuretics.Some studies have also supported the use of agents such as orlistat,somatostatin,octreotide and etilefrine.Paracentesis and surgical interventions in the form of transjugular intrahepatic portosystemic shunt(commonly known as TIPS),peritoneal shunt,angiography with embolization of a leaking vessel,and laparotomy remain as treatment options for cases refractory to medical management.
