Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Simple aspiration is generally the initial management for the purpose of diagnosis and cyst volume reduction. However, the recurrence rate has been reported to be high (40% to 59%), depending on the number of aspirations and extent of fluid evacuation. After simple fine-needle aspiration, most cystic lesions (around 80%) refill and enlarge over time.
Surgery is a long-established therapeutic option for benign thyroid nodules. However, the cost of thyroid surgery, risk of temporary or permanent complications, and impact on quality of life remain relevant concerns.
Ultrasound-guided percutaneous ethanol injection (PEI) The mechanism of ethanol sclerotherapy is that ethanol induces cellular dehydration and protein denaturation, which are followed by coagulation necrosis, reactive fibrosis, and small-vessel thrombosis.
As regard (PEI)Pain is the most common side effect, other mild side effects or complications occurred in small numbers of patients like: Facial flushing, Mild dizziness, Intracystic haemorrhage, drunken sense, Perithyroidal leakage. There are other side effects, including transient vocal cord palsy, respiratory distress requiring emergency surgical treatment, and venous thrombosis, in sporadic cases.
Percutaneous Polidocanol sclerotherapy (PPI) may be a potential alternative to ethanol for the treatment of benign cystic and predominantly cystic thyroid nodules.Polidocanol is a liquid detergent sclerosant developed in 1936 as a topical and local anaesthetic consisting of 95% hydroxy poly ethoxydodecane and 5% ethyl alcohol. It has been used as a treatment for hemorrhoidal disease, venous malformations, symptomatic hepatic cysts, renal cysts, gastric varices, and digital mucous cysts.
The mechanism of treating cyst is probably destroying endothelial cells of capsular wall which causes aseptic inflammation; thus endothelial tissue atrophies and cyst cavity adhere and occlude.
The side effects are mild including mild localized pain and mild or moderate fever after PPI. So, PPI could be a safe and effective alternative to treat benign cystic or predominant cystic thyroid nodules.

RANDOMIZED
PARALLEL
The sample was calculated using G\*power software 3.1.9.2., based on the following assumptions: Main outcome variable is the difference between mean value of:
Group (A): 15 patients will be treated by Ultrasound-Guided Percutaneous Polidocanol Injection Group (B): 15 patients will be treated by Ultrasound-Guided percutaneous ethanol injection
TREATMENT
NONE
Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Polidocanol group
Polidocanol is injected in the thyroid cyst under ultrasound guidance.
Polidocanol
Polidocanol is injected under complete aseptic conditions. Before the treatment the diameter and volume of each nodule is calculated. To prevent serious hemorrhage, vessels located along the approach route will be carefully evaluated by using Doppler US.
Alcohol group
Alcohol is injected in the thyroid cyst under ultrasound guidance.
Alcohol
Alcohol is injected under complete aseptic conditions. Before the treatment the diameter and volume of each nodule is calculated. To prevent serious hemorrhage, vessels located along the approach route will be carefully evaluated by using Doppler US.
