This document describes a study assessing the safety and effectiveness of a new percutaneous laser ablation technique called Light and Flight Technique (LFT) for treating benign thyroid nodules. The study involved treating 19 patients with benign thyroid nodules using LFT, which involves multiple overlapping laser illuminations within the nodule using a single optic fiber. Preliminary results found the procedure was safe, with no major complications, and resulted in a mean volume reduction of 30-40% at 1 month and 50-70% at 6 months. LFT appears to be a safe and effective procedure for treating benign thyroid nodules that results in significant volume reduction while using a low-cost single optic fiber.

Background: Several sonographically guided injection methods have been described to treat carpal tunnel syndrome.
In most cases, the medication diffuses through the carpal tunnel to the site of maximum compression of the nerve after
being injected proximally. In this article, we describe a novel method of sonographically guided carpal tunnel injection that
utilizes a distal-to-proximal, in-plane, and transligamentous approach. This novel method may provide ergonomic as well
as safety advantages to both clinicians and patients, and should be considered by those performing carpal tunnel injections.

Abstract
Objective: To assess the outcome of arthroscopic release in patients with cronicalchronic lateral epicondylitis. Materials and methods: Arthroscopic release in three patients with lateral epicondylitis was performed. The Mayo Elbow Performance Index (or Mayo Elbow Performance score) was used pre and post surgical treatment. Sample: Two females and one male. The patients were principal labourers and not athletes. Patients had significant pain and pain was the principal symptom that affected the score of the performance index.
Results: Scores on the performance index improved after surgery. No neurological complications were reported and early return to normal daily activities was noted.
Conclusion: Arthroscopic treatment was an alternative safe and effective method for treating chronic lateral epicondiyitis in three cases. This method makes it possible to simultaneously scan the articulation to diagnostic and treatment associated diseases. It is necessary most wide assays and comparative studies for establish sure treatment protocols.
2. under local anesthesia (2% lidocaine at the point of the
puncture) and conscious sedation with intravenous propofol
and a bolus of fentanyl and ketamine. For ultrasound guidance
we used a Mylab70 (Esaote, Genova, Italy) with a 13 MHz
linear transducer.
LFT-LA treatment is performed with the patient lying in supine
position and the neck hyperextended, by introducing one
21 gauge guiding needle along the cranio-caudal diameter of
the thyroid nodule. Under ultrasound guidance the tip of the
needle is positioned in the most posterior, lateral and inferior
part of the nodule. A 300 microns optic fiber is then inserted
through the needle until the distal 5 to 7 mm of the fiber exit
the tip of the needle and are in direct contact with the thyroid
tissue. Laser illuminations are performed through a power
source of 3 W.
LFT consist of multiple overlapping low and intermediate
energy laser illuminations using a single active optic fiber
that is sequentially moved in the nodule. At the end of each
illumination the active tip of the optic fiber is repositioned using
the free hand technique and a new illumination is performed
in the part of the nodule adjacent to the previously treated
area thus permitting the overlapping of the ablated regions.
The total number of intranodular repositioning of the active
tip and subsequent illuminations depend on the volume of
the nodule. The LFT-LA technique allow to spread laser light
in the complete volume of the nodule thus permitting to use
reduced energy laser illuminations. To realize this modified
laser ablation technique in a safety manner the peripheral 10
mm of the nodule or the parts of the nodule adjacent to the
trachea and the danger triangle are treated by low energy
illuminations ( up to 300 Joule), while the central part of the
nodule is treated with higher energy illuminations (between
500 and 800 Joule).
To plan the LFT-LA the nodule is ideally divided in multiple
virtual areas. To better understand the sequences of the LFT
procedure these virtual areas are identified adapting the normal
anatomic nomenclature to ultrasound views. With the patient
in the supine position we therefore ideally divide the nodule in
a medial (paratracheal), lateral (juxtacarotid) and intermediate
part in the sagittal plane. In the coronal plane we divide the
nodule in a posterior( prevertebral), anterior ( adiacent to the
sternocleidomastoid muscle and subcutaneous tissue) and
a central part. In the axial plane the nodule is divided in an
inferior (caudal), intermediate and superior (cranial) part.
As a general rule, to avoid posterior shadowing from gas
formation during the procedure, laser illuminations are
directed from inferior to superior in the axial plane, from
lateral to medial in the sagittal plane, and from posterior to
anterior and in the coronal plane.
We usually start the procedure at the most posterior and
inferior part of the lateral side of the nodule. We then move
the tip of the needle medially in the sagittal plane to treat
the most inferior and posterior part of the intermediate part
of the nodule. We then consecutively and repetitively move
the needle superiorly in the axial plane and anteriorly in the
coronal plane from lateral to medial in the sagittal plane
covering all the volume of the nodule. Starting the treatment
at the lateral side of the nodule permit to reduce the risk
of lesioning the medially located trachea and neurovascular
bundle. Usually the medial part of the nodule is treated with
a new needle insertion and illuminations are started from
the most inferior, posterior and medial part of the nodule.

right thyroid lobe. Image A2: numbers indicate the sequence of the
illuminations in the inferior pole of the nodule in the axial plane.Blu spots
indicate the ablated area at each illumination At each illumination 600
joules are delivered at each blu spot. The red circle indicate the global
ablated area at the end of the procedure.
The procedure begin at the inferior, posterior and lateral side of the
nodule: illumination 1 = number 1.
The needle is moved medially to the inferior, medial and posterior part of
the nodule: illumination 2 = number 2 .
The needle is then directed laterally and anteriorly in the anterior-inferior
pole of the nodule: illumination 3 = number 3.
The needle is then directed medially in the anterior-inferior pole of the
nodule: illumination 4 = number 4.

procedures a total amount of 4800 joules were delivered.
The procedure begin at the inferior, posterior and lateral side of the

pole of the nodule: illumination 7 (number 7, image B).

3. The tip of the needle is subsequently moved superiorly and
anteriorly in the medial part of the nodule. A distance of
at least 10 mm is always maintained between de tip of the
needle and the thyroid capsule. In large nodules it may be
necessary to realize multiple consecutive re-insertions of the
guiding needle to cover the complete volume of the nodule
while maintaining a safety orientation of the active tip of the
optic fiber with respect to the cervical perithyroid structures.
Performing multiple reinsertion of the single active optic fiber
permit to avoid direct firing toward the common carotid artery,
the trachea or the recurrent laryngeal nerve branches. These
multiple re-insertions due to the small diameter of the 21
G needle do not cause any permanent skin lesion, are well
tolerated by the patient. In our experience the presence of
two operators, usually an endocrinologist and a radiologist
permit the constant control of both the ultrasound and laser
equipment allowing a tailored procedure for each patient with
a precise energy administration respecting the safety margins
of treated nodule and allow the operators to have a fulltime
control of the relation of the active tip of the needle with
relevant cervical structures.
A dose of 0.5 mg / kg iv methylprednisolone is administered, at
the beginning of the procedure, and 40 mg pantoprazole are
administered iv to prevent obstruction of the airway by edema.
Prophylaxis of nausea and vomiting is realized by iv
administration of 4 mg of ondansetron and analgesia is
complemented with paracetamol 1g iv.
After the procedure corticosteroids are given in a short
downward pattern of 8 days. (Prednisone 15 mg / day for
one day followed by a rapid 5 days descending doses) and
analgesics (Paracetamol PO. 1g / 8h vs Ketorolac 30 mg po.)
if pain persists.
To assess the volume of the ablated area (volume of coagulation
obtained with ALP) B-mode ultrasound, color Doppler and
contrast enhanced ultrasound evaluation) is performed
immediately after the procedure.
Clinical and ultrasound follow-up was performed at one week,
one, 3, 6 and 12 months after the procedure to evaluate
volume reduction and exclude treatment related complications.
Results
The mean procedure time for LFT-AL was 40. No major
complications occurred.
The mean volume reduction for LFT-LA was 30-40% at 1
month and 50-70 % at 6 months.
When comparing the volume reduction associated to the
internal consistency of the nodules, the solid nodules presented
a 65-78% overall volume reduction at 6 months compared to
a 40-60% for microcystic-spongiform nodules.
Nodules with volume > 24 ml (.> 4.5 cm in diam. max) presented
a lower reduction in size at 1, 3, 6 months: of 40-56%
The 12-month follow-up is ongoing.
All patients have remained asymptomatic at 1, 3, 6 and 12
months post LFT-AL and no patient was referred to surgery
due to procedure related complication or nodule re- growth.
During follow-up, thyroid function remained normal in all
patients and in 3 patients with subclinical hyperthyroidism
thyroid function it has been normalized to 6 months post LFT-LA.
Conclusions
In our initial experience the LFT- LA appears to be a safe
and effective procedure in the treatment of benign thyroid
nodules. Volume reduction seems to be more rapid being
significant already at 1 month as regarding the conventional
LA. Similar results of those reported with conventional LA
technique in terms of volume reduction were registered at 6
and 12 months.
More over LTF-LA for benign thyroid nodules is a cost effective
and easily reproducible procedure since only one active fiber is
used in each treatment. Like others ablative techniques such
RF repeated LFT- LA should be considered for large volume
nodules, with the advantage of the lower cost of the LFT- LA
when compared to cooled-RF.
Finally we consider that in the future LFT could be easily applicable
to cooled laser device for very large volume thyroid nodules.

Abstract
Objective
To evaluate the feasibility, safety and efficacy of ultrasound-
guided percutaneous laser ablation (PLA) for the treatment of
papillary thyroid microcarcinoma (PTMC).
Methods
Three patients with single PTMC diagnosed by fine-needle
aspiration cytology underwent ultrasound-guided PLA. After
treatment, the size and blood flow signals of the lesions
were evaluated with conventional ultrasonography, and
the ablation extent of the lesions were assessed by contrast
enhanced ultrasonography (CEUS) immediately and 3 days
after PLA. Ultrasound-guided fine-needle aspiration biopsy
was performed at 30 days after PLA.
Results
All of the 3 patients successfully completed PLA under
local anesthesia. The procedure was well tolerated without
complications, and the patients required no analgesics.
Instead of the lesion observed before PLA, conventional
ultrasonography showed a broad heterogeneous area devoid
of vascular signals after PLA. CEUS at once and 3 days after PLA
confirmedthatthecompletelyavascularareafullyencompassed
the treated lesion. Ultrasound-guided fine-needle aspiration
biopsy at 30 days after PLA demonstrated necrotic tissues and
inflammatory cells without viable neoplastic cell.
Conclusions
Ultrasound-guided PLA is a safe, effective, and feasible
procedureforthetreatmentofpapillarythyroidmicrocarcinoma.
