The goal of this clinical trial is to compare the safety and effectiveness of the three intercostal nerve blocks used in pain management in uniportal (one port) thoracoscopic surgeries: internal intercostal nerve blocks (ICNB), external ICNB, and Intercostal catheters. Participants will be randomly assigned to three groups: * First group will undergo internal intercostal nerve block * Second group will be given external intercostal nerve block * Third group will have an intercostal catheter Researchers will compare the three groups to see their impact on post-operative pain management in uniportal VATS.
The main questions this clinical trial aims to answer are: 1. To study post-VATS complications, such as: postoperative air leak, post-operative pain, hypoxemia, atelectasis, bleeding, wound infection, pneumonia, Deep Vein Thrombosis, pulmonary embolism and their association with the different approaches of ICNBs. 2. To address the cost-effectiveness of the intercostal nerve block approaches. 3. To study the participants' level of satisfaction after VATS following each procedure of ICNB. 4. To address the relationships between the intercostal nerve block approaches and participants' characteristics such as age, gender, BMI, medical and surgical history, smoking, and alcohol history. This study is a randomized controlled trial that will take place at Al-Ahli Hospital and Saint Joseph Hospital. The trial will involve 90 participants, who will be randomly assigned to three groups. Of these, group 1 will include 30 participants who'll receive an internal intercostal nerve block, group 2: 30 participants will receive an external intercostal block, and group 3 are the 30 participants who will have an intercostal catheter inserted. Data will be collected from the participants' themselves through a questionnaire before the surgery. The participants will be followed up after the surgery (3, 6, 24 hours post-operatively) in order to obtain the numerical rating scale. A written informed consent will be sought. Data Analysis will be done through International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) for Windows Version 16.

The effectiveness of the three approaches of pain management after 3 hours of uniportal VATS
To Compare the effectiveness of different approaches of intercostal nerve blocks (internal ICNB, external ICNB, Intercostal catheters) for pain management after uniportal VATS through assessing the pain scores of the participants 3 hours after the surgery using the Numerical rating scale (NRS11). The NRS is a 11-point scale, where "0" represents "no pain", and "10" represents "the most severe pain imaginable" at 3 hours after the uniportal VATS. Points from "1 - 3" means mild pain, "4 - 6" indicates moderate pain, and "7 - 10" indicates severe pain.
Time frame: From participants enrollment until 3 hours after the surgery

The NRS is a 11-point scale, where "0" represents "no pain", and "10" represents "the most severe pain imaginable" at 6 hours after the uniportal VATS. Points from "1 - 3" means mild pain, "4 - 6" indicates moderate pain, and "7 - 10" indicates severe pain.
Time frame: From participants enrollment until 6 hours after the surgery

The effectiveness of the three approaches of pain management after uniportal VATS, during different positions
To Compare the effectiveness of different approaches of intercostal nerve blocks (internal ICNB, external ICNB, Intercostal catheters) for pain management after uniportal VATS, during coughing, deep breathing, lying down, moving and chest tube removal, through the use of NRS11, 24 hours post-operatively. The NRS is a 11-point scale, where "0" represents "no pain", and "10" represents "the most severe pain imaginable" at the three different positions. Points from "1 - 3" means mild pain, "4 - 6" indicates moderate pain, and "7 - 10" indicates severe pain.
Time frame: 24 hours post-operatively
The effect of the three different approaches of pain management on post-operative hypoxemia
Understand the relationships between different approaches of pain management used and post-operative hypoxemia after each approach. Hypoxemia is defined as hypoperfusion or low oxygen concentrations in the artery that leads to a decrease the delivery of oxygen to the tissues. It will be measured using pulse oximetry at 3 hours, and compared to the patient's baseline before the surgery. The use of pulse oximeter will help in the early diagnosis of hypoxemia, and lead to early correction if it is present. Hypoxaemia will be graded as follows: * Mild hypoxaemia - 86-90% * Moderate hypoxaemia - 81-85% * Severe hypoxemia - 76-80% * Extreme hypoxaemia - \<76%
Time frame: From participants enrollment until 3 hours after the uniportal VATS

The effect of the three different approaches of pain management on post-operative atelectasis
Understand the relationships between different approaches of pain management used and post-operative atelectasis after each approach. Atelectasis will be defined as collapse or incomplete expansion of the pulmonary parenchyma. The incidence of atelectasis in each approach will be identified through chest x-ray that will be done immediately after the surgery and repeated 24 hours later. The signs of atelectasis on chest X-ray that will be considered are: increased opacity of the atelectatic segment, displacement of inter-lobar fissures towards the atelectatic segment, upward displacement of the diaphragm ipsilateral of atelectatic segment and crowding of pulmonary vessels and bronchi in atelectatic segment. Other signs that will be considered are: over-inflation of the healthy lung and displacement of trachea and other thoracic structures towards the side of atelectasis.
Time frame: From participants enrollment until 24 hours after the uniportal VATS
The effect of the three different approaches of pain management on post-operative Pneumothorax
Understand the relationships between different approaches of pain management used and post-operative pneumothorax after each approach. Pneumothorax will be defined as a condition when air in the lung leak in the pleural cavity (following the surgical procedure). Pneumothorax will be diagnosed through a chest x-ray, which is the gold standard for the detection of pneumothorax. Pneumothorax will be classified as the following: * Small pneumothorax: when the space is less than 2 cm, measured from the chest wall to the edge of the lung at the level of the hilum on chest x-ray. * Large pneumothorax: when the space is larger than 2 cm, measured from the chest wall to the edge of the lung at the level of the hilum on chest x-ray. This outcome will be identified through chest x-ray that will be done immediately after the surgery and repeated 24 hours later to look for any new pneumothorax onset during the first 24 hours post-operation.
Time frame: From participants enrollment until 24 hours after the uniportal VATS
Cost-effectiveness of the three approaches
The cost-effectiveness of the 3 approaches will be measured through relying on the pain Medication as a Cost Factor: The cost-effectiveness of the three analgesic approaches will be estimated by analyzing the consumption of additional pain medications. This includes both opioids and non-opioids. The total amount of additional pain medications administered to each patient will be calculated as a proxy for cost. This approach assumes that higher medication requirements correlate with lower effectiveness of the approach, thereby affecting the overall cost-effectiveness. The average medication costs across the three groups will be compared to determine the most cost-effective approach.
Time frame: From participants enrollment until the study completion, an average of 7 months
Participants' satisfaction level
Identify the Participants' satisfaction level after each approach through a linear scale from 1 to 10 used in the questionnaire (The question will be: How satisfied had you been with the results of your pain treatment while in the hospital?) 1 means completely unsatisfied, 10 means completely satisified
Time frame: From participants enrollment until 24 hours after the uniportal VATS
