Trial summary

Adequate postoperative analgesia is difficult to achieve in patients undergoing laparoscopic sleeve gastrectomy (LSG). Epidural anesthesia is technically difficult due to subcutaneous fat, which increases the risk of serious complications. Read more about this study

About this study

Official title: Effects of M-TAPA Block on Postoperative Pulmonary Functions in Laparoscopic Bariatric Surgery: A Randomized Controlled Study

Adequate postoperative analgesia is difficult to achieve in patients undergoing laparoscopic sleeve gastrectomy (LSG). Epidural anesthesia is technically difficult due to subcutaneous fat, which increases the risk of serious complications. Moreover, patients in this condition often have comorbidities that require anticoagulation therapy. Although ultrasound-guided Transversus Abdominis Plane (TAP) block may be useful, it is still controversial.

Recently, modified thoracoabdominal nerve block via perichondrial approach (M-TAPA) has been reported as a new and promising technique that provides effective analgesia in the anterior and lateral thoracoabdominal wall.

The most common reason for hospitalization after laparoscopic surgery is pain after nausea and vomiting. In addition, superficial and tachypneic breathing resulting from the patient's inability to breathe deeply with pain causes closure of small airways and increase in intrapulmonary shunts, resulting in hypoxia. Postoperative pain management is important not only to prevent pain but also to reduce pulmonary complications that may occur due to changes in lung function and to reduce mortality and morbidity by controlling the stress response.

In this study, The investigators investigated the effect of modified thoracoabdominal nerve block via perichondrial approach (M-TAPA) on pulmonary function in patients undergoing laparoscopic bariatric surgery under general anesthesia.

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Functions and Pain Management, run by Zonguldak Bulent Ecevit 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 5 inclusion and 11 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 22 Apr 2025. 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?

FEV1/FVC ratio (time frame: during the procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Apr 2025.
