Modified vs. Conventional Laparoscopic TAPP for Inguinal Hernia

January 19, 2026 updated by: Taseen Imran, University of Health Sciences Lahore

A Randomized Controlled Trial Comparing Modified Tumescent vs. Conventional Laparoscopic TAPP for Inguinal Hernia Repair

This study aims to compare the outcomes of two laparoscopic techniques for repairing inguinal hernias: the modified tumescent technique (MT-TAPP) and the conventional laparoscopic transabdominal preperitoneal technique (CL-TAPP). The primary goal is to determine which technique provides better outcomes in terms of operative time, ease of pre-peritoneal space dissection, postoperative pain, and the formation of seromas. The study will involve 60 patients diagnosed with unilateral inguinal hernias, randomly assigned to either group. Participants in Group A will undergo the MT-TAPP procedure, which involves pre-peritoneal infiltration of a local anesthetic solution to improve dissection and reduce pain. Group B will undergo the standard CL-TAPP procedure. Data will be collected on various outcome measures and analyzed to identify which technique leads to quicker recovery, less postoperative pain, and fewer complications. The results of this study will help guide surgical decisions and improve patient outcomes in inguinal hernia repair.

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

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.

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age: 18 to 50 years.
  • Gender: Both male and female participants.
  • Condition: Diagnosed with unilateral inguinal hernia (as per operational definition).
  • Health Status: ASA I-III (American Society of Anesthesiologists physical status classification), indicating that the patient is fit for surgery.
  • Consent: Participants must be able to provide informed consent to participate in the study.

Exclusion Criteria:

  • Femoral Hernias.
  • Incarcerated or Strangulated Hernia.
  • Recurrent Hernias (as per medical record).
  • Serious Systemic Diseases:

  • Pregnancy (if applicable).
  • Allergy to Anesthesia or the substances used in the tumescent solution (lidocaine, epinephrine, saline).
  • Uncontrolled Diabetes or other medical conditions that might interfere with the healing process.

Arms and Interventions

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: Modified Tumescent Laparoscopic TAPP (MT-TAPP)
Other: Modified Tumescent Laparoscopic TAPP (MT-TAPP) for the first group.
In this intervention, participants will undergo laparoscopic inguinal hernia repair using the modified tumescent technique. This technique involves pre-peritoneal infiltration of a solution containing lidocaine, epinephrine, and saline. The tumescent solution is injected into the peritoneum to create a "tumescent" effect, making the tissues easier to dissect and reducing bleeding. This approach aims to improve surgical visibility, reduce operative time, minimize postoperative pain, and shorten the learning curve for less experienced surgeons. The rest of the procedure follows the standard laparoscopic TAPP repair, with mesh placement and peritoneal closure.
Active Comparator: Conventional Laparoscopic TAPP (CL-TAPP)
Other: Conventional Laparoscopic TAPP (CL-TAPP)
In this intervention, participants will undergo the conventional laparoscopic transabdominal preperitoneal (TAPP) hernia repair. This standard technique involves placing three ports to access the inguinal region, followed by dissection of the pre-peritoneal space and placement of a mesh to repair the hernia. The conventional method does not use tumescent infiltration and relies solely on the surgeon's skill to navigate the anatomical structures. This approach is well-established and commonly used in inguinal hernia repairs, but it may be associated with longer operative times and more postoperative pain compared to the modified technique.

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.
