REduced Pain After Bariatric Surgery - Sleeve Gastrectomy (REPABS-SG)

April 21, 2024 updated by: Vincenzo Bruni, Fondazione Policlinico Universitario Campus Bio-Medico
This study aims to analyze the effect of laparoscopic guided transversus abdominis plane (LG-TAP) block compared to placebo for postoperative analgesia following laparoscopic sleeve gastrectomy. One group of participants received a (LG-TAP) block with local anesthetic while the other group received (LG-TAP) block with saline solution (placebo).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: LG-TAP
The laparoscopic guided TAP Block was performed at the beginning of surgery, injecting 15 ml of Ropivacaine Hydrochloride 0.5% on each side, using an atraumatic needle (10/15 cm length, 20 Gauge diameter) close to the anterior axillary line, between the iliac crest and the subcostal margin. Correct needle tip positioning between the transverse muscle of the abdomen and the internal oblique was verified through laparoscopic guidance.
Procedure: LG-TAP block with local anesthetic
The laparoscopic guided TAP Block was performed by surgeon at the beginning of surgery, injecting 15 ml of Ropivacaine 0.5% on each side, using an atraumatic needle (10/15 cm length, 20 Gauge diameter) close to the anterior axillary line, between the iliac crest and the subcostal margin. Correct needle tip positioning between the transverse muscle of the abdomen and the internal oblique was verified through laparoscopic guidance.
Procedure: Port site infiltration
Prior the surgical incision, an infiltration of the laparoscopic access using a total of 10 ml Ropivacaine 0.5% was performed by surgeon
Placebo Comparator: SALINE
The laparoscopic guided TAP Block was performed at the beginning of surgery, injecting 15 ml of Saline solution (NaCl 0.9%) on each side, using an atraumatic needle (10/15 cm length, 20 Gauge diameter) close to the anterior axillary line, between the iliac crest and the subcostal margin. Correct needle tip positioning between the transverse muscle of the abdomen and the internal oblique was verified through laparoscopic guidance.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain Score
Time Frame: 24 hours
A numerical rating scale (NRS) from 0 (no pain) to 10 (worst imaginable pain) will be used to evaluate pain at rest during 24 hours after surgery
24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
