About this trial

The objective of this study is to evaluate the Symani System's safety and effectiveness for microsurgical anastomosis during open lymphatic reconstruction in the head and neck.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

At least 22 years of age

Patients with acquired head and neck lymphedema with external lymphedema or both external and internal lymphedema

Patient agrees to participate in the study, return for all required follow-up visits, complete all study procedures, and has willingly provided written informed consent after receiving all information related to the study, its requirements, and the robotic-assisted procedure

Patient has a clinical indication for a microsurgical anastomosis of vessels between 0.1 and 2.5 mm in conjunction with lymphatic reconstruction of the head and neck

Disqualifiers

Patient who is incapable and/or unwilling to provide informed consent

Patients with irreversible head and neck lymphedema, defined as stage 3 of the MD Anderson Cancer Center Head and Neck Lymphedema Rating Scale

Active systemic infection under treatment with intravenous antibiotics

Clinically significant cardiovascular, digestive, respiratory, endocrine, or central nervous system disorders, previous mental disorders, or other disorders that may significantly affect the data collection or the ability to comply with the protocol per the investigator's discretion

Trial outcomes

Primary outcomes

1

Intraoperative anastomosis patency prior to closure.

Intraoperative anastomosis patency prior to closure will be measured for each robotic anastomosis using indocyanine green (ICG) fluorescence imaging and will be evaluated prior to closure of the procedure site during the index procedure.

Time frame
The duration of the participants' index procedure.
2

Freedom from device-related adverse events

All adverse events will be evaluated from the start of the index procedure through 30 days post index procedure.

Time frame
The duration of the participants' index procedure through 30 days.

Secondary outcomes

1

Change in flow pathways

Change in flow pathways will be assessed by an ICG lymphangiography

Time frame
From the pre-operative visit through 6 months post index procedure.
2

Change in MD Anderson Lymphedema Rating Scale for facial lymphedema

Scale ranges from 0-3, the higher score indicating worse disease state.

Time frame
From the pre-operative visit through 6 months post index procedure.
3

Assessment of Lymphedema of the Head and Neck Area (ALOHA) method for lymphedema measurement

Time frame
From the pre-operative visit through 6 months post index procedure.
4

Change in Head and Neck Lymphedema and Fibrosis Symptom Inventory

It contains 33 items (symptoms) which are answered Yes or No. If the response is Yes to any given item, the patient is asked to rate the intensity of the symptom on a 5-point Likert scale. Each symptom then receives a score ranging from 0 (does not experience the symptom) to 5 (experiences the symptom with severe intensity).

Time frame
From the pre-operative visit through 6 months post index procedure.
