The Silent Spill: A Case Report on Navigating the Challenges of a Chyle Leak.

A chyle leak occurs due to a discontinuity in the thoracic duct. It is a very rare condition that occurs as a result of injuries or surgical procedures. Chyle is rich in antibodies. Its functions are to maintain the equilibrium of the human fluid system, draw in fatty acids, and maintain the natural immunity of humans. It is identified by the increased quantity of drains, which show a milky white color and clinically palpable supraclavicular collection. It is a condition that has to be managed as soon as possible as it leads to serious nutritional debridement, electrolyte imbalance, and complications such as chylothorax and chylomediastinum. It is managed by various surgical and conservative approaches, such as ligating the thoracic duct, using sclerosing agents, giving total parenteral nutrition, and restricting physical activities, as discussed in this article.

Ultrasonographic and CT-scan findings of splenic active chylous effusion and postlymphangiography enhancement in a cat with chylothorax associated with splenic angiosarcoma.

A 12-year-old domestic shorthair cat was presented with relapsing noncardiogenic chylothorax. CT-lymphangiography of the thorax confirmed bilateral pleural effusion without evidence of an underlying intra-thoracic origin. Abdominal CT-lymphangiography revealed a 2.6 cm diameter splenic mass surrounded by chylous effusion actively collecting during ultrasonographic assessment. Following splenectomy, histopathological analysis revealed that the splenic mass exhibited characteristics indicative of splenic angiosarcoma. This case report highlights the utility of advanced thoracic and abdominal imaging, notably CT-lymphangiography, in the diagnostic evaluation of chylothorax in cats. The identification of a splenic mass encased in chylous effusion should prompt a proactive case management strategy.

A case report of chyle leakage after axillary node clearance in a patient with breast cancer.

Key Clinical Message: Chyle leakage is a rare postoperative complication of breast cancer, and conservative treatments should be prioritized, with careful monitoring of drainage volume and timely surgical intervention when conservative treatments are ineffective. Abstract: Chyle leaks following surgery for breast cancer are seldom encountered. Management varies with no consensus in the literature. This paper reports a case of a chylous leak after axillary dissection in a patient with breast cancer eventually cured with conservative treatment and discusses management options varied with both conservative and surgical options available to clinicians.

Management of Major Complications After Esophagectomy.

Esophagectomy remains a procedure with one of the highest complication rates. Given the advances in medical and surgical management of patients and increased patient survival, the number of complications reported has increased. There are different grading systems for complications which vary based on severity or organ system, with the Esophageal Complications Consensus Group unifying them. Management involves conservative intervention and dietary modification to endoscopic interventions and surgical reintervention. Treatment is etiology specific but rehabilitation and patient optimization play a significant role in managing these complications by preventing them. Management is a step-up approach depending on the severity of symptoms.

Chyle and Bile Leak Following Open Cholecystectomy: A Rare Complication.

Gallstone disease is extremely common and frequently and safely treated by cholecystectomy. Chyle leak is a rare but significant side effect of many abdominal surgeries with rarely reported post-cholecystectomy. In this case, we report a 78-year-old lady with multiple comorbidities and symptomatic gallstones who underwent open cholecystectomy complicated by bile and chyle leak, which was successfully managed with endoscopic retrograde cholangiopancreatography (ERCP) and stenting for bile leak and conservative management for the chyle leak, which included drainage, low-fat diet, and octreotide.

Lymphatic Chyle Duct Injury and Identification During Laparoscopic Sleeve Gastrectomy Preventing Postoperative Chylous Ascites.

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 drainage through percutaneous cholecystostomy: an extremely rare complication.

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.

Incidence and Risk Factors for Chyle Leaks After Neuroblastic Tumor Resection: A Systematic Review of Published Studies.

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.

Systematic Lymphatic Repair for Reduction of Postoperative Lymphatic Leak Following Neuroblastoma Resection.

BACKGROUND: Gross total resection of neuroblastoma is associated with lymphatic leaks that can delay postoperative resumption of treatment. To prevent postoperative lymphatic leak, we introduced systematic lymphatic repair (SLR), which involved oversewing the entire edge of the disrupted lymphatic plane after neuroblastoma resection. We sought to study the impact of SLR on postoperative lymphatic leak and time to return to treatment. METHODS: We reviewed 60 neuroblastoma patients who underwent gross total resection at KK Women's and Children's Hospital. Patient, disease, and operative factors were correlated with surgical drainage, treatment delay and length of stay (LOS). Among patients with sufficient records, the interaction between variables associated with drainage, delay and LOS outcomes were compared in 14 patients who had SLR versus 35 historical controls who had targeted lymphatic repair (TLR). RESULTS: Postoperative drain duration and volume were significantly higher in tumors with ≥2 image-derived risk factors (IDRFs, P = 0.005 and P = 0.013, respectively) or vessel encasement (P = 0.031 and P = 0.024, respectively). Longer LOS was significantly associated with ≥2 IDRFs (P = 0.006). All forms of suture repair of lymphatics and use of Tachosil™ were associated with significantly longer postoperative drain duration (P < 0.05); the former was also associated with significantly higher total drain volume (P < 0.05) - indicating appropriate use of these adjuncts in patients at risk of chyle leak. In patients who had suture repair of lymphatics, SLR was significantly associated with reduced postoperative interval to chemotherapy resumption (P = 0.014, two-way ANOVA). CONCLUSION: A systematic approach to repair of lymphatic channels following neuroblastoma resection can significantly reduce time to postoperative resumption of treatment. TYPE OF STUDY: Clinical Research. LEVEL OF EVIDENCE: III.

Chyle leak after head and neck surgeries: a comprehensive review of diagnosis and management strategies.

Chyle leaks are uncommon complications after head and neck surgeries. Although uncommon, such a complication is noteworthy mention due to its perplexing diagnosis and management strategies. This scoping review aims to highlight and emphasize the diagnosis and management options proposed in the literature. A comprehensive search was performed in PubMed, Google Scholar, Cochrane Library, and Scopus databases and identified 617 articles that were reduced to 40 studies and reports after applying the eligibility criteria. Although numerous treatment options ranging from simple, conservative measures to invasive surgical procedures have been mentioned for low-output, high-output, and massive leaks, there is no concrete evidence on the best method. Thus, a combination of management options must be customized by case for optimum results.

Octreotide's role in the management of post-esophagectomy chylothorax.

The use of octreotide in managing intrathoracic chyle leak following esophagectomy has gained popularity in the adult population. While the benefits of octreotide have been confirmed in the pediatric population, there remains limited evidence to support its use in the adults post-esophagectomy. Thus, we performed a single-institution cohort study to characterize its efficacy. The study was performed using a prospective, single-center database, from which clinicopathologic characteristics were extracted of patients who had post-esophagectomy chyle leaks. Kaplan-Meier and multivariable Cox regression analyses were performed to investigate the effect of octreotide use on chest tube duration (CTD), hospital length of stay (LOS), and overall survival (OS). In our cohort, 74 patients met inclusion criteria, among whom 27 (36.5%) received octreotide. Kaplan-Meier revealed no significant effect of octreotide on CTD (P = 0.890), LOS (P = 0.740), or OS (P = 0.570). Multivariable Cox regression analyses further corroborated that octreotide had no effect on CTD (HR = 0.62, 95% confidence interval [CI]: 0.32-1.20, P = 0.155), LOS (HR = 0.64, CI: 0.34-1.21, P = 0.168), or OS (1.08, CI: 0.53-2.19, P = 0.833). Octreotide use in adult patients with chyle leak following esophagectomy lacks evidence of association with meaningful clinical outcomes. Level 1 evidence is needed prior to further consideration in this population.

Minimally Invasive Treatment of Chyle Leak After Thyroidectomy and Cervical Lymph Node Dissection in Patients with Thyroid Carcinoma: Results of a Study Involving 36 Patients.

Objective: Chyle leak (CL) after head and neck surgery is a rare but well-known complication. In patients with high-output leakage, the treatment can be complicated. This study aims to report on a recent innovation in lymphatic intervention for treating such patients. Materials and Methods: A retrospective review of 36 patients with chyle leak after neck surgery for thyroid cancer was conducted to assess the efficacy of percutaneous lymphatic embolization and thoracic duct (TD) disruption. Results: Antegrade catheterization of the thoracic duct was achieved in 31 of 36 patients (86.1%). Therefore, embolization of the thoracic duct and thoracic duct branches was performed in 26 and 5 patients, respectively. In 5 cases of unsuccessful antegrade catheterization into the thoracic duct, transcervical access embolization was performed in 2 patients, and TD disruption (TDD) was performed in 3 patients. The pooled overall technical success rate of lymphatic embolization was 33/36 patients (91.7%). One patient who underwent thoracic duct embolization (TDE) with technical success (1/33 patients) but clinical failure had additional treatment directly sclerosing the TD under computed tomography scan. Cervical fluid collection sclerotherapy was done in 7 patients as an additional treatment. Resolution of the chyle leak after procedures was observed in all patients (100%). The mean time to resolution was 3 days (1-7 days). There was no complication intra and after procedures. Conclusion: TDE, selective TD branches embolization and TDD are safe and effective minimally invasive treatments for CL post-surgery for thyroid carcinoma. Sclerosing cervical fluid collection contributes to clinical success.

Thoracic Duct Embolization for Treatment of Chyle Leakage After Thyroidectomy and Neck Dissection.

OBJECTIVE: This study aimed to evaluate the safety and efficacy of intranodal lymphangiography and thoracic duct embolization (TDE) for chyle leakage (CL) after thyroid surgery. MATERIALS AND METHODS: Fourteen patients who underwent intranodal lymphangiography and TDE for CL after thyroid surgery were included in this retrospective study. Among the 14 patients, 13 underwent bilateral total thyroidectomy with neck dissection (central compartment neck dissection [CCND], n = 13; left modified radical neck dissection (MRND), n = 11; bilateral MRND, n = 2), and one patient underwent left hemithyroidectomy with CCND. Ten patients (76.9%) had high-output CL (> 500 mL/d). Before the procedure, surgical intervention was attempted in three patients (thoracic duct ligation, n = 1; lymphatic leakage site ligation, n = 2). Lymphangiographic findings, technical and clinical successes, and complications were analyzed. Technical success was defined as the successful embolization of the thoracic duct after access to the lymphatic duct via the transabdominal route. Clinical success was defined as the resolution of CL or surgical drain removal. RESULTS: On lymphangiography, ethiodized oil leakage near the surgical bed was identified in 12 of 14 patients (85.7%). The technical success rate of TDE was 78.6% (11/14). Transabdominal antegrade access was not feasible due to the inability to visualize the identifiable cisterna chyli or a prominent lumbar lymphatic duct. Among patients who underwent a technically successful TDE, the clinical success rate was 90.1% (10/11). The median time from the procedure to drain removal was 3 days (with a range of 1-13 days) for the 13 patients who underwent surgical drainage. No CL recurrence was observed during the follow-up period (ranging from 2-44 months; median, 8 months). There were no complications, except for one case of chylothorax that developed after TDE. CONCLUSION: TDE appears to be a safe and effective minimally invasive treatment option for CL after thyroid surgery, with acceptable technical and clinical success rates.

Bilateral chylothorax following left neck dissection and literature review.

Chylothorax without chyle cervical leakage after neck dissection it is extremely rare. We report a case of bilateral chylothorax without chyle cervical leakage after left neck dissection, wherein partial left upper jaw resection and left radical neck dissection were performed in a 46-year-old woman who was diagnosed with left upper gingival cancer. The thoracic duct was ligated and cut during surgery and, although no obvious leakage of lymph was observed, dyspnea and cough reflex during deep inhalation were observed from the third postoperative day. Approximately 600 mL of yellowish-white pleural effusion was aspirated during bilateral thoracentesis, and chylothorax was diagnosed based on clinical findings and biochemical analysis results. The patient was put on a low-fat diet on the fourth postoperative day. Pleural effusion disappeared on imaging examination 16 days after thoracentesis.

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.

Nutritional management of chyle leak after head and neck surgery: a systematic review and proposed protocol for management.

PURPOSE: Chyle leaks are a rare complication of neck surgery causing local damage, impairing healing and compromising free flaps. High output leaks can result in electrolyte imbalances and malnutrition. Nutritional management such as restricting the absorption of triglycerides is believed to reduce chyle, allowing spontaneous resolution of a leak. Dietary preparations and management can aid in reducing chyle production. There are no clear guidelines to aid nutritional decision-making in this complex scenario. METHODS: A systematic review of the literature was carried out to identify studies evaluating nutritional management of chyle leaks in patients after neck dissections. RESULTS: Ten studies were identified evaluating the role of nutritional therapy in the management of patients with chyle leaks after neck dissections. The level of evidence was low. Several studies identified that low volume leaks (defined as < 1000 mls per day) often resolved by dietary management and other conservative measures. High volume leaks rarely resolved with conservative measures alone. Parenteral nutrition had an established role in this context. CONCLUSIONS: There is limited evidence to guide dietary restriction and introduction of oral diet in patients with chyle leak after major head and neck surgery. Based on available evidence, local guidelines for the nutritional management of patients identified with a chyle leak were produced and adopted by the Trust and the head and neck MDT. A national database for voluntary contribution of prospective data would help to generate better quality management protocols.

Post-operative chyle leak following nephrectomy: Inference from tertiary care center and review of literature.

OBJECTIVES: Lymphatic channels (LC) are not as prominent as blood vessels, so they tend to get damaged during surgical procedures. It can present with chyle leak in the postoperative period. We aimed to study the occurrence of chyle leak in patients undergoing nephrectomy and its management. METHODS: During the period of January 2021 and January 2023, 158 adult patients underwent nephrectomy for various reasons like non-functioning kidney, donor nephrectomy, and malignancy. We retrospectively analyzed data of patients who had chyle leak after nephrectomies. RESULTS: Eight patients out of the 158 patients (5.06%) undergoing nephrectomy developed chyle leak. One out of these eight patients underwent nephrectomy by open approach while seven underwent laparoscopic approach. All eight patients who had chyle leak undergone left sided nephrectomy. Six patients of chyle leak could be managed with dietary modification while two patients needed octreotide therapy for treatment. Higher Body Mass Index (BMI; p-value = 0.012), left sides nephrectomy (p-value = 0.013), h/o pyelonephritis (p-value = 0.005) were associated with higher incidence of chyle leak on univariate analysis. While on multivariate analysis no factor was found to be independently associated with chyle leak. Hospital stay was significantly prolonged in patients with chyle leak (p-value = 0.007). CONCLUSION: Chyle leak is not a very rare complication after nephrectomy. Patients with higher BMI, who undergo left sided nephrectomies and patients who had history of pyelonephritis or infectious complications had higher incidence of chyle leak. Most cases can be managed with conservative management (CM). Chyle leak is associated with a prolonged hospital stay.

Traumatic Chylothorax Following Pulmonary Segmentectomy: A Case Report and Review of Postoperative Investigation and Management.

The incidence of iatrogenic traumatic chylothorax is on the rise secondary to the preferred use of minimally invasive thoracic surgery over thoracotomy. Most reported causes of chylothorax occur following pneumonectomy or lobectomy. There have been no reported cases of traumatic chylothorax following segmentectomy according to our literature review. Complications following lung resection typically include pneumonia, atelectasis, or prolonged air leak. Here, we present a rare case of postoperative chylothorax following minimally invasive segmentectomy to diagnose an enlarging singular pulmonary nodule. This condition was diagnosed with fluid analysis after CT imaging revealed a postoperative unilateral pleural effusion. Interestingly, the patient had a loculated pleural effusion that mimicked a pericardial effusion and empyema. Our patient was managed conservatively with a low-fat diet and short-term pleural drainage without the need for repeat surgical intervention. The importance of imaging interpretation following lung resection along with a working differential diagnosis, appropriate examination, and testing can assist with the diagnosis of this known, but rare, postoperative complication.
