Brief summary in lay language

Lymphatic leakage is a severe complication of surgical procedures. In the context of our study, we want to observe whether, after a direct nodal puncture, Lipiodol reaches the site of lymph leakage, whether lymph leakage is detectable using lipiodol.

Brief summary in scientific language

Lymphatic leakage (LL) is a serious complication of certain surgical procedures, such as nephrectomy, lymph node resection or esophagectomy. The reason for this is a alteration of lymphatics during the surgical procedure. LL can occur in any part of the lymphatic system and cause complications such as chylothorax, lymphocele and lymphatic ascites. The imaging of the LL is possible using ultrasound- or CT-guided direct puncture of an nearby associated lymph node and administration of Lipiodol. After successfull imaging of LL using fluoroscopy visualisation of lymphatic drainage is possible. In our study, we want to observe whether, following a usually direct nodal puncture, Lipiodol reaches the location of lymphatic leakage, weather the LL itself is detectable. Sensitivity and specificity for the visualization and detection of lymphatic leakage/lymphocele will be evaluated. Further results about embolizing effects of lipiodol may be shown and quantified using the gathered information.

Interventions, Observational Groups

Arm 1:
As part of routine intervention, the patient is hospitalized. The inclusion criteria for the planned recruitment are evaluated by present CT or MRI imaging. Immediately prior to treatment, a blood and drainage sample is taken. The therapy is carried out by the physican after patient confirmed informed consent is obtained, image-controlled (sonography or CT) puncture of a suitable lymph node and instillation of Lipiodol is performed. As part of the intervention, after local anesthesia, a very fine needle is inserted percutaneously and a defined volume of a fat-soluble contrast agent is injected, either directly into a lymph node or into a lymphatic vessel. Depending on the localization of the lymphatic leak and the presence of accessible lymph nodes, the puncture takes place in the groin or via a dorsal approach for retroperitoneal targets. If necessary, before and / or after treatment, local control is achieved by further non-invasive imaging, e.g. computed tomography (CT). Immediately after the intervention, as well as 14 and 28 days, as well as 3, 6 and 12 months after the intervention, complaints, general condition and amount of drainage are recorded in the outpatient clinic.

Endpoints

Primary outcome:
Lipiodol use during routine lymphatic drainage.
Secondary outcome:
Detection of lymphatic leaks using lipiodol in the context of study-controlled data acquisition. Evidence of leakage during clinical routine follow-up by ultrasound or MRI or if clinically indicated by a CT scan.
