Risk factors, impact and treatment of postoperative lymphatic leakage in children with abdominal neuroblastoma operated on by laparotomy. BMC Surg 2024; 24:168. [PMID: 38811926 PMCID: PMC11134958 DOI: 10.1186/s12893-024-02459-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 05/17/2024] [Indexed: 05/31/2024] Open
Abstract
BACKGROUND Lymphatic leakage is one of the postoperative complications of neuroblastoma. The purpose of this study is to summarize the clinical characteristics and risk factors of lymphatic leakage and try to find effective prevention and treatment measures. METHODS A retrospective study included 186 children with abdominal neuroblastoma, including 32 children of lymphatic leakage and 154 children of non-lymphatic leakage. The clinical information, surgical data, postoperative abdominal drainage, treatment of lymphatic leakage and prognosis of the two groups were collected and analyzed. RESULTS The incidence of lymphatic leakage in this cohort was 14% (32 children). Through univariate analysis of lymphatic leakage group and non-lymphatic leakage group, we found that lymphatic leakage increased the complications, prolonged the time of abdominal drainage and hospitalization, and delayed postoperative chemotherapy (p < 0.05). In this cohort, the median follow-up time was 46 (95% CI: 44-48) months. The follow-up data of 7 children were partially missing. 147 children survived, of which 23 had tumor recurrence (5 children recurred in the surgical area). 37 children died, of which 32 had tumor recurrence (9 children recurred in the operation area). In univariate analysis, there was no statistical difference in overall survival (p = 0.21) and event-free survival (p = 0.057) between lymphatic leakage group and non-lymphatic leakage group, while 3-year cumulative incidence of local progression was higher in lymphatic leakage group (p = 0.015). However, through multivariate analysis, we found that lymphatic leakage did not affect event-free survival, overall survival and cumulative incidence of local progression in children with neuroblastoma. Resection of 5 or more lymphatic regions was an independent risk factor for lymphatic leakage after neuroblastoma surgery. All 32 children with lymphatic leakage were cured by conservative treatment without surgery. Of these, 75% (24/32) children were cured by fat-free diet or observation, 25% (8/32) children were cured by total parenteral nutrition. The median drain output at diagnosis in total parenteral nutrition group was higher than that in non-total parenteral nutrition group (p < 0.001). The cut-off value was 17.2 ml/kg/day. CONCLUSIONS Lymphatic leakage does not affect the prognosis of children with neuroblastoma, but long-term drain output caused by lymphatic leakage will still adversely affect postoperative complications and follow-up treatment, which requires attention and active treatment measures. More attention should be paid to the children with 5 or more lymphatic regions resection, and the injured lymphatic vessels should be actively found and ligated after tumor resection to reduce the postoperative lymphatic leakage. Early application of total parenteral nutrition is recommended for those who have drain output at diagnosis of greater than 17.2 ml/kg/day. LEVEL OF EVIDENCE Level III, Treatment study (Retrospective comparative study).

Intranodal Ultrasound-Guided Percutaneous Methylene Blue Injection for the Identification of Leakage Point during Laparoscopic Repair of Refractory Chylous Ascites after Laparoscopic Lymphadenectomy for Kidney Cancer. Case Rep Urol 2022; 2022:3817554. [DOI: 10.1155/2022/3817554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/09/2022] [Accepted: 11/01/2022] [Indexed: 11/22/2022] Open
Abstract
Chylous ascites is an uncommon complication after surgery that can result in malnutrition and immunodeficiency. Therefore, surgical interventions are reserved for refractory patients, and the primary success factor for these interventions is locating the point of leakage, which is often tricky. We describe a case of a 56-year-old male with chylous ascites after laparoscopic radical nephrectomy and lumbo-aortic lymphadenectomy for kidney cancer. The patient was initially managed with dietary modifications and drainage placement. Afterward, lymphography with Lipiodol, percutaneous embolization of the leakage point, and total parenteral nutrition were established. Finally, the patient underwent laparoscopic repair after identifying the leakage point by injecting methylene blue through an inguinal node. Complete resolution was achieved, and no complications related to the procedure were recorded. Intranodal methylene blue injection can be an invaluable tool to identify the point of leakage in selected patients to improve the outcomes of surgical repair of refractory chylous ascites.

[PMID: 35524233 PMCID: PMC9077892 DOI: 10.1186/s12893-022-01619-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 04/25/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Carbon nanoparticle suspension (CNS) was applied to locate the lymphatic leakage in chylous ascites (CA). However, the flow speed and distance of the CNS were particularly decreased in the following two cases (patient 5 and 6). This study aimed to investigate and improve the flow speed and distance of the CNS via a rat model. METHODS Seven patients with CA were accepted for surgery in the past two years. Clinical data were recorded. Rats were divided into two groups to confirm the hypothesis regarding whether accepting milk or orally administered food before surgery was the key factor in CA surgery with CNS. The animals were divided into 2 groups: experimental group of 5 rats receiving fat emulsion injection (2 g/kg) 30 min before the operation and control group of 5 rats receiving saline. We analyzed flow speed and distance of the CNS in two groups of rats. The hypothesis established was that CNS movements pattern differ depending on the degree of capillary lymph duct filling. Finally, the late case reconfirmed the hypothesis again. RESULTS In animal experiments, the CNS in the preoperative high-fat feeding group moved faster and over a longer distance than that in the control group (0.51 ± 0.09 cm vs. 0.19 ± 0.10 cm, respectively; p < 0.05). Based on this, the CNS was applied to the seventh patient, who had been given a diet with a slightly higher fat content 3 days before the operation, and marked improvement with a complete cure was recorded. CONCLUSIONS The capillary lymph duct was beginning to swell after dietary intake. The dilation of the lymph vessel could make it easier for the CNS to move and reach the leakage.
