RESUMO
BACKGROUND: Chylous ascites is caused by disruption of the lymphatic system, which is characterized by the accumulation of a turbid fluid containing high levels of triglycerides within the abdominal cavity. The two most common causes are cirrhosis and tuberculosis, and colon signer ring cell carcinoma (SRCC) due to the use of immunosuppressants is extremely rare in cirrhotic patients after liver transplantation, making it prone to misdiagnosis and missed diagnosis. CASE SUMMARY: A 52-year-old man who underwent liver transplantation and was administered with immunosuppressants for 8 months was admitted with a 3-month history of progressive abdominal distention. Initially, based on lymphoscintigraphy and lymphangiography, lymphatic obstruction was considered, and cystellar chyli decompression with band lysis and external membrane stripping of the lymphatic duct was performed. However, his abdominal distention was persistent without resolution. Abdominal paracentesis revealed allogenic cells in the ascites, and immunohistochemistry analysis revealed adenocarcinoma cells with phenotypic features suggestive of a gastrointestinal origin. Gastrointestinal endoscopy was performed, and biopsy showed atypical signet ring cells in the ileocecal valve. The patient eventually died after a three-month follow-up due to progression of the tumor. CONCLUSION: Colon SRCC, caused by immunosuppressants, is an unusual but un-neglected cause of chylous ascites.
RESUMO
A 56-year-old man presented to our hospital with dyspnea on exertion for two months. Bilateral pleural effusions were found, and a close examination revealed a chylothorax, including adenocarcinoma. The primary tumor could not be identified by systemic examination. Therefore, the patient was diagnosed with cancer of unknown primary origin (CUP) presenting with chylothorax. Chemotherapy was administered for CUP, and thoracentesis, pleurodesis, ascites puncture, and nutritional therapy were performed for chylothorax and chylous ascites. Although drainage frequency and tumor marker levels (CA19-9, DUPAN-2, and Span-1) temporarily decreased, disease control deteriorated, and the patient died 12 months after the initial diagnosis.
RESUMO
Phospholipase A2 receptor (PLA2R)-associated membranous nephropathy is an important cause of nephrotic syndrome that can lead to a variety of systemic manifestations. Chylous ascites and bilateral renal vein thrombosis are rare manifestations in adult nephrotic syndrome, and there have been no reported cases demonstrating both chylous ascites and bilateral renal vein thrombosis in patients with PLA2R-associated membranous nephropathy. Here, we report the first case of PLA2R-associated membranous nephropathy complicated by renal vein thrombosis and chylous ascites successfully treated with anticoagulation and rituximab. A 65-year-old African American male presented with abdominal pain for four days, hematochezia for one day, and lower extremity edema for one year. Blood pressure was 158/73 mmHg and other vital signs were normal. Physical examination revealed abdominal distention, periumbilical tenderness, and bilateral lower extremity edema. Laboratory analysis showed high serum creatinine, hypoalbuminemia, hyperlipidemia, and proteinuria on 24-hour urine chemistry, all consistent with nephrotic syndrome. Abdominal computed tomography scan demonstrated nonocclusive bilateral renal vein thrombosis with ascites. Paracentesis revealed chylous ascites. Continuous heparin infusion was started for thrombosis. Esophagoduodenoscopy and colonoscopy did not reveal a source of bleeding. Serum anti-PLA2R was found positive, suggesting membranous nephropathy. Rituximab, along with warfarin switched from heparin, successfully controlled disease activity. Chylous ascites in nephrotic syndrome is thought to be associated with bowel edema. In our case, we hypothesize that renal vein thrombosis caused lymphatic fluid leakage by increasing lymphatic pressure. The case illustrates the importance of considering membranous nephropathy as a cause of chylous ascites and renal vein thrombosis. Development of lymphatic imaging techniques is warranted to clarify the pathophysiology.
RESUMO
Introduction: Chyloperitoneum arises from lymph leakage into the abdominal cavity, leading to an accumulation of milky fluid rich in triglycerides. Diagnosis can be challenging, and mortality rates vary depending on the underlying cause, with intestinal volvulus being just one potential acute cause. Despite its rarity, our case series highlights chyloperitoneum associated with non-ischemic small bowel volvulus. The aims of our study include assessing the incidence of this association and evaluating diagnostic and therapeutic approaches. Material and Methods: We present two cases of acute abdominal peritonitis with suspected small bowel volvulus identified via contrast-enhanced computed tomography (CT). Emergency laparotomy revealed milky-free fluid and bowel volvulus. Additionally, we conducted a systematic review up to 31 October 2023, identifying 15 previously reported cases of small bowel volvulus and chyloperitoneum in adults (via the PRISMA scheme). Conclusions: Clarifying the etiopathogenetic mechanism of chyloperitoneum requires specific diagnostic tools. Magnetic resonance imaging (MRI) may be useful in non-emergency situations, while contrast-enhanced CT is employed in emergencies. Although small bowel volvulus infrequently causes chyloperitoneum, prompt treatment is necessary. The volvulus determines lymphatic flow obstruction at the base of the mesentery, with exudation and chyle accumulation in the abdominal cavity. Derotation of the volvulus alone may resolve chyloperitoneum without intestinal ischemia.
RESUMO
Chylous ascites is an uncommon pathology with low incidence following hepato-pancreato-biliary surgery, there are no cases reported in the international literature following the associating liver partition and portal vein ligation for stage hepatectomy (ALPPS) procedure. It is caused by abnormal intraperitoneal accumulation of lymph fluid in the abdominal cavity secondary to obstruction or injury to the chyle cistern or its tributaries. We describe the case of a 49-year-old woman diagnosed with colon cancer and liver metastasis. ALPPS was performed, on a first and second stage, presenting a high drainage output as well as change in the characteristics of the drainage fluid. The diagnosis of chylous ascites was confirmed by finding triglyceride levels in the drainage fluid at 300 mg/dL. Medical treatment was started based on a hyper-protein diet and fat restriction, supplemented with medium-chain triglycerides and somatostatin analog, with fistula resolution. It can be managed with medical treatment.
RESUMO
INTRODUCTION: Chylous ascites is a rare but morbid condition following removal of residual mass in non-seminomatous germ cell tumours following chemotherapy. CASE PRESENTATION: We hereby present the case of a 20-year-old man who had undergone RPLND with complete surgical excision. A lesion of the Cisterna chyli complicated the operation. The post-operative course was marked by the appearance of chylous ascites. The conservative management strategy for this complication was successful, but only after a month. CLINICAL DISCUSSION: Chylous ascites is a rare but morbid condition following removal of residual mass in non-seminomatous germ cell tumours following chemotherapy. Conservative management based on a high-protein diet with fat restriction and medium-chain triglyceride supplementation, and somatostatine are usually successful. Surgery should be reserved for situations that are refractory to treatment. CONCLUSIONS: We report our successful management and, we also analysed the different management protocols using our experience and review of the literature.
RESUMO
We present a case of intraoperative detection of an iatrogenic chyle duct injury during laparoscopic sleeve gastrectomy. The chyle duct injury was identified and managed by ligature, preventing postoperative chylous ascites.

Chylous ascites is the accumulation of triglyceride-rich lymphatic fluid in the peritoneal cavity. We present the case of a four-month-old male admitted for abdominal distension. A large volume of ascites was confirmed by imaging. Paracentesis indicated chylous aspirate and drainage was performed using a pigtail catheter. Total parenteral nutrition was initiated and fluconazole prophylaxis was implemented for seven days. Twenty-six days after admission, abdominopelvic magnetic resonance imaging showed trace ascites but no signs of lymphatic malformation. He began transitioning to nasogastric feeds with plans to eventually resume oral feeds. This case not only highlights the limitations in our abilities to definitively identify the etiology of pediatric chylous ascites but also demonstrates how chylous ascites management can carefully combine conservative and surgical strategies to optimize patient outcomes.
RESUMO
Chylous ascites is a rare manifestation of decompensated cirrhosis that is associated with increased short-term mortality. Exclusion of other etiologies must be performed to allow for appropriate management, which itself can be a challenge in the setting of decompensated cirrhosis. We report a case of chylous ascites in a patient with decompensated cirrhosis that was successfully managed with octreotide before liver transplantation.
RESUMO
BACKGROUND: Chyle leakage/ascites after surgical resection of neuroblastic tumors may delay the start of chemotherapy and worsen prognosis. Previous studies have reported a highly variable incidence and risk factors remain largely unknown. This study aims to analyze the true incidence of chyle leaks and ascites and seeks to identify risk factors and optimal treatment strategies. METHODS: Medline/Embase databases were searched according to PRISMA guidelines. Literature reviews, case reports, and non-English papers were excluded. Data were extracted independently following paper selection by 2 authors. RESULTS: The final analysis yielded 15 studies with N = 1468 patients. Chylous ascites was recorded postoperatively in 171 patients (12%). Most patients experiencing chyle leaks were successfully treated conservatively with drainage, bowel rest, parenteral nutrition and octreotide with variable combinations of these treatment options. 7/171 (4%) patients required operative exploration to control troublesome persistent chyle leaks. In risk factor analysis, higher tumor stage was significantly associated with the risk of chyle leak (P < 0.0001) whereas no correlation was observed with adrenal vs non-adrenal tumor location, INRG risk groups and tumor laterality. CONCLUSION: Chyle leakage after surgery for neuroblastic tumors is a common morbid complication occurring in some 12% of patients. Higher INSS tumor stage portends greater risk(s). Conservative therapy strategies appear successful in the majority of cases. To avert this complication meticulous mesenteric lymphatic ligation is recommended especially for those patients with higher tumor stage(s) requiring extensive radical surgery including retroperitoneal lymph node resection. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Systematic review.

Refractory chylous ascites can cause significant nutritional and immunologic morbidity, but no clear treatment has been established. This article introduces a case of a 22-year-old female patient with an underlying lymphatic anomaly who presented with refractory chylous ascites after laparoscopic adnexectomy for ovarian teratoma which aggravated after thoracic duct embolization. Ascites (>3,000 mL/d) had to be drained via a percutaneous catheter to relieve abdominal distention and consequent dyspnea, leading to significant cachexia and weight loss. Two sessions of hybrid lymphovenous anastomosis (LVA) surgery with intraoperative mesenteric lymphangiography guidance were performed to decompress the lymphatics. The first LVA was done between inferior mesenteric vein and left para-aortic enlarged lymphatics in a side-to-side manner. The daily drainage of chylous ascites significantly decreased to 130 mL/day immediately following surgery but increased 6 days later. An additional LVA was performed between right ovarian vein and enlarged lymphatics in aortocaval area in side-to-side and end-to-side manner. The chylous ascites resolved subsequently without any complications, and the patient was discharged after 2 weeks. The patient regained weight without ascites recurrence after 22 months of follow-up. This case shares a successful experience of treating refractory chylous ascites with lymphatic anomaly through LVA, reversing the patient's life-threatening weight loss. LVA was applied with a multidisciplinary approach using intraoperative mesenteric lipiodol, and results showed the possibility of expanding its use to challenging problems in the intraperitoneal cavity.
RESUMO
Cancers of unknown primary (CUPs) pose diagnostic and therapeutic challenges because of their aggressive nature and elusive identification through conventional diagnostic means. This case report presents a unique finding in a 57-year-old female patient who, alongside her CUP, developed a cavernous mesenteric lymphangioma-a rare lymphatic malformation that is more commonly observed in pediatric populations. The interrelation between CUPs, chylous ascites, and lymphangiomas is explored, shedding light on this uncommon occurrence. Our patient's journey began with a CUP diagnosis, marked by metastatic adenocarcinoma. Subsequent symptoms led to the discovery of a mesenteric lymphangioma. The case unfolds the patient's diagnostic challenges, surgical interventions, and postoperative course. By highlighting the distinctive features of our case, we aim to contribute to the limited understanding of the interplay between lymphatic malformations and metastatic malignancies.
RESUMO
Chyle leak is a rare but potentially morbid complication of abdominal surgery. There have been seven reported cases of chylous ascites following cholecystectomy, but no such occurrences are reported with percutaneous cholecystostomy tube (PCT) insertion. We report the case of a 67-year-old female with stage IVb recurrent uterine papillary serous carcinoma and extensive abdominal surgical history including a paraesophageal hernia repair, and a robotic hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, gastrocolic omentectomy, and hepatoduodenal lymphadenectomy. The patient presented with clinical findings suggestive of acute cholecystitis and decision was made to proceed with PCT placement. The PCT was dislodged and replaced during her course and several days after chylous output was noted from the PCT. The remainder of her hospital course was complicated by persistent distributive shock, adrenal insufficiency, and continued chyle leak. She ultimately was transitioned to inpatient hospice and died shortly after.
RESUMO
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.

To report results of interventional treatment of refractory non-traumatic abdomino-thoracic chylous effusions in patients with lymphoproliferative disorders. 17 patients (10 male; mean age 66.7 years) with lymphoproliferative disorders suffered from non-traumatic chylous effusions (chylothorax n = 11, chylous ascites n = 3, combined abdomino-thoracic effusion n = 3) refractory to chemotherapy and conservative therapy. All underwent x-ray lymphangiography with iodized-oil to evaluate for and at the same time treat lymphatic abnormalities (leakage, chylo-lymphatic reflux with/without obstruction of central drainage). In patients with identifiable active leakage additional lymph-vessel embolization was performed. Resolution of effusions was deemed as clinical success. Lymphangiography showed reflux in 8/17 (47%), leakage in 2/17 (11.8%), combined leakage and reflux in 3/17 (17.6%), lymphatic obstruction in 2/17 (11.8%) and normal findings in 2/17 cases (11.8%). 12/17 patients (70.6%) were treated by lymphangiography alone; 5/17 (29.4%) with leakage received additional embolization (all technically successful). Effusions resolved in 15/17 cases (88.2%); 10/12 (83.3%) resolved after lymphangiography alone and in 5/5 patients (100%) after embolization. Time-to-resolution of leakage was significantly shorter after embolization (within one day in all cases) than lymphangiography (median 9 [range 4-30] days; p = 0.001). There was no recurrence of symptoms or post-interventional complications during follow-up (median 445 [40-1555] days). Interventional-radiological treatment of refractory, non-traumatic lymphoma-induced chylous effusions is safe and effective. Lymphangiography identifies lymphatic abnormalities in the majority of patients and leads to resolution of effusions in > 80% of cases. Active leakage is found in only a third of patients and can be managed by additional embolization.

Chylous ascites is the exudation from lymphatic content to the peritoneum and is a rare situation that mostly occurs following medical causes like neoplasms or cirrhosis. However, trauma to the lymphatic system due to compression by masses or altered anatomy can be a trigger too. We describe a rare combination of a primary small bowel volvulus in a young healthy adult causing chylous ascites. Obstruction caused by a primary small bowell volvulus can re-arrange the lymphatics anatomy increasing their flow pressure which can lead to rupture and leak. This is an emergent scenario that needs to be addressed quickly because of bowel ischaemia. CT scan is the gold standard to expedite diagnosis and go to surgical treatment. Although it can be an impactful finding, treatment of the cause behind chylous ascites results in complete resolution without any bowel resection.
RESUMO
INTRODUCTION AND IMPORTANCE: Chylous ascites is an uncommon form of ascites characterized by milky fluid rich in triglycerides. It is associated with poor lymphatic drainage. We report a case of chylous ascites revealing a follicular lymphoma. CASE PRESENTATION: A 73-year-old man presented with a 6-month history of abdominal distension attributed to a chylous ascitis. The thoraco-abdomino-pelvic CT scan revealed voluminous intra- and retroperitoneal mass inseparable from the duodeno-pancreatic block and encompassing the mesenteric vessels, inferior vena cava and renal vessels; abundant ascites and multiple mediastinal, coeliomesenteric, retroperitoneal, iliac and inguinal adenomegalia. The diagnosis of follicular lymphoma was retained through a radio-guided biopsy of the retroperitoneal mass. The patient had weekly paracentesis and immuno-chemotherapy. The course was unfavorable, marked by infection of the ascites fluid after two cycles of immuno-chemotherapy. Our patient developed severe sepsis and died. CLINICAL DISCUSSION: Chylous ascites in conjunction with follicular lymphoma is an exceptional presentation. The pathophysiological mechanism is an impediment to subdiaphragmatic lymphatic drainage caused by external pressure, leading to leakage of dilated subserosal lymphatic ducts into the peritoneal cavity. Histological confirmation is fundamental to manage chylous ascites resulting from lymphomas. CONCLUSION: Chylous ascites revealing lymphoma is a unique condition. The key to management is the treatment of the underlying etiology.
RESUMO
Here, we report a rare case of small bowel volvulus with chylous ascites. A 93-year-old man with a medical history of angina pectoris presented to the emergency department with abdominal pain. Computed tomography revealed a whirl sign of the mesenteric vessels with the axis of the superior mesenteric artery. A diagnosis of small bowel volvulus was made, and emergency surgery was performed. Laparoscopic examination revealed chylous ascites. Due to severe intestinal edema and difficulty in manipulating the forceps, surgery was transferred to a laparotomy. The entire small bowel was twisted 360° counterclockwise, requiring manual untwisting. Examination of the intestinal tract after untwisting revealed no evidence of ischemia or necrosis. However, because a diverticulum was observed on the mesenteric side of the upper jejunum and considering the influence of secondary small bowel volvulus, partial small bowel resection was performed. The patient had a favorable postoperative course.
RESUMO
A 40-year-old woman underwent laparoscopic common iliac lymphadenectomy for metastasis from rectal cancer. Two weeks after the surgery, she was found to have massive chylous ascites. After failure of conservative treatment, bilateral inguinal intranodal lymphangiography was performed. No definite extravasation was observed while lipiodol injected through the left inguinal node was ascending. When we punctured the right inguinal lymph nodes and started the injection of lipiodol, extravasation of diluted lipiodol was noted at the level of the first sacrum. Careful observation revealed that the ascending lipiodol became diluted in the cisterna chyli, refluxed through the median paraaortic route, leaked from the excised left common iliac lymph vessel, and flowed into the abdominal cavity. Lipiodol used in lymphangiography did not reduce chylous ascites at all. Twenty-seven days after lymphangiography, laparoscopic lymphatic ligation was performed, and the chylous ascites disappeared completely. CT obtained 40 days after surgical repair revealed disappearance of ascites and enlargement of the thoracic duct, which had not been observed on preoperative lymphangiography. Notably, lymphatic reflux from the cisterna chili can occur without obstruction of the thoracic duct and may result in chylous ascites.
RESUMO
Chylous ascites (CA) is a rare complication following renal surgery. Here we present the case of a 28-year-old female who developed CA after a robotic left partial nephrectomy. After failing conservative management, she underwent successful robotic-assisted diagnostic laparoscopy and ligation of lymphoperitoneal fistulae. The higher incidence of CA after left versus right-sided renal surgery may be explained by the para-aortic drainage of the intestinal lymphatic channels. Surgical intervention should be considered when conservative management fails.
