About this study
Official title: Comparison of the Efficacy of US-guided M-Tapa Block vs OSTAP for Postoperative Analgesia in Patients After Laparoscopic Inguinal Hernia Repair Surgery
Inguinal hernia repair is the most common of abdominal surgical procedures and is usually performed laparoscopically. Many factors play a role in the pain that develops after surgery and is generally considered to be visceral pain. Phrenic nerve irritation due to CO2 insufflation into the peritoneal cavity, abdominal distention, tissue trauma, sociocultural status, and individual factors are the factors that play a role in the occurrence of this pain.
Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block performed with ultrasound (US) is a new block that provides effective analgesia in the anterior and lateral thoracoabdominal areas, where local anesthetic is applied only to the lower side of the perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome levels and abdominal lateral wall and may be an opioid-sparing strategy with satisfactory quality recovery in patients undergoing laparoscopic surgery.

Oblique Subcostal Transversus Abdominis Plane Block (OSTAP) is one of the body blocks used especially for postoperative analgesia. OSTAP, defined by Hebbard in 2010, is a subcostal version of the Transversus abdominis plane block (TAP block), based on the injection of local anesthetic from the lower edge of the costal margin, obliquely between the obliquus externus and Transversus abdominis muscles.
This study aimed to compare the efficacy of US-guided M-TAPA block and OSTAP block for postoperative analgesia management after laparoscopic inguinal hernia repair surgery. Our primary aim is to compare postoperative pain scores (0. hour NRS), and our secondary aim is to evaluate the use of rescue analgesics (opioids), side effects associated with opioid use (allergic reaction, nausea, vomiting), and patient satisfaction (Likert scale).

Inguinal hernia repair is the most common of abdominal surgical procedures and is usually performed laparoscopically. Many factors play a role in the pain that develops after surgery and is generally considered to be visceral pain. Phrenic nerve irritation due to CO2 insufflation into the peritoneal cavity, abdominal distention, tissue trauma, sociocultural status, and individual factors are the factors that play a role in the occurrence of this pain.
Postoperative pain is acute pain accompanied by an inflammatory process due to surgical trauma and gradually decreases with tissue healing. Postoperative pain is a serious problem that reduces patient comfort and delays the patient's return to work after surgery. Successful postoperative analgesia occurs in the patient due to pain; It is a known fact that it prevents many of the effects such as being unable to breathe easily and delayed mobilization.
Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block performed with ultrasound (US) is a new block that provides effective analgesia in the anterior and lateral thoracoabdominal areas, where local anesthetic is applied only to the lower side of the perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome levels and the abdominal lateral wall and may be an opioid-sparing strategy that provides a satisfactory quality improvement in patients undergoing laparoscopic surgery. M-TAPA block provides analgesia in the abdominal region at the T5-T11 level. Sonoanatomy is easy to visualize and the spread of local anesthetic can be easily seen under US guidance. With the cephalocaudal spread of the local anesthetic solution, analgesia occurs in several dermatomes. In the literature, there are studies investigating the effectiveness of M-TAPA block for postoperative pain management in bariatric surgery.
Oblique Subcostal Transversus Abdominis Plane Block (OSTAP) is one of the body blocks used especially for postoperative analgesia. OSTAP, which Hebbard defined in 2010, is a subcostal version of the Transversus abdominis plane block (TAP block) and is based on the injection of local anesthetic from the lower edge of the costal margin, obliquely between the obliquus externus and Transversus abdominis muscles. OSTAP; Although it is frequently used in laparoscopic abdominal surgery, it is a very difficult block to implement. There are studies reporting that it provides successful analgesia after various abdominal surgeries.
This study aimed to compare the efficacy of US-guided M-TAPA block and OSTAP block for postoperative analgesia management after laparoscopic inguinal hernia repair surgery. Our primary aim is to compare postoperative pain scores (0. hour NRS), and our secondary aim is to evaluate the use of rescue analgesics (opioids), the side effects associated with opioid use (allergic reaction, nausea, vomiting), and patient satisfaction (Likert scale).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Postoperative managementDrug
Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. Postoperative patient evaluation will be performed by a pain nurse blinded to the procedure. 100 mg tramadol will be performed for rescue analgesia.
| Study group | Role | What they receive |
|---|---|---|
| Group M-TAPA = M-TAPA Block Group | Active comparator | Under aseptic conditions, a high-frequency linear probe will be placed on the costochondral angle in the sagittal plane. Then the probe will be slightly angled deeply to visualize the lower view of the perichondrium. We will perform M-TAPA with total of 60 ml (30 ml for each side) of %0,25 bupivacaine. Receives: Drug: Postoperative management |
| Group OSTAP = OSTAP Block Group | Active comparator | In the supine position, the transducer is placed in the subcostal region in an oblique plane, and a 15-20 cm needle is first inserted between the rectus abdominis and the transversus abdominis muscle and advanced towards the iliac crest in the interfascial plane. The block location will be confirmed with 5 ml of saline. After the block location is confirmed, a total of 30 ml + 30 ml of 0.25% bupivacaine (total of 60 ml for both sides) will be injected bilaterally. Receives: Drug: Postoperative management |

Questions about this trial
What is this clinical trial studying?
A study testing Postoperative management in people with Inguinal Hernia, run by Medipol University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative pain scores (Numerical Ratin Scala; 0=no pain, 10=the worst pain felt) (time frame: Postoperative 24 hours period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05476510, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2023.
