Study summary

Open tension-free mesh repair (Lichtenstein) and laparoscopic totally extraperitoneal (TEP) repair are the most commonly preferred techniques for inguinal hernia surgery. There's still a debate going on about which of these two techniques (open versus laparoscopic) is effective. This prospective randomized study aimed at comparing the early and long-term results of these two techniques (TEP vs. Lichtenstein).

Read the detailed description

Various studies comparing the laparoscopic totally extraperitoneal (TEP) and Lichtenstein techniques have been reported. These studies have shown that TEP repair is associated with less postoperative pain and faster recovery. However, there are different views on the long-term (recurrence, chronic pain, etc.) results of the two techniques. This study was designed to compare the short- and long-term outcomes of open tension-free mesh repair technique(Lichtenstein) and laparoscopic repair technique(TEP).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients who were diagnosed with inguinal hernia (primary, recurrent, unilateral, bilateral)
  • (ASA) score of I and II
  • Gave to participate in the study

Exclusion criteria

Exclusion Criteria:

  • Patients with scrotal, strangulated, or obstructed hernia
  • Periumbilical or subumbilical incision scar (median, right or left paramedian)
  • Undergoing prostatectomy or abdominal bladder surgery
  • Pfannenstiel incision scar
  • >3
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
