Prolene hernia system versus Lichtenstein repair for inguinal hernia: a meta-analysis

Area of Science:

• General Surgery
• Minimally Invasive Surgery
• Surgical Innovation

Background:

• Lichtenstein repair is the standard for inguinal herniorrhaphy.
• Concerns exist regarding mesh use and postoperative chronic pain.
• New mesh technologies aim to reduce recurrence and chronic pain.

Purpose of the Study:

• Compare the Prolene Hernia System (PHS) with Lichtenstein repair for inguinal hernias.
• Evaluate recurrence rates, chronic pain, and other surgical outcomes.
• Assess the efficacy of novel mesh technology in hernia repair.

Main Methods:

• Meta-analysis of randomized-controlled trials (RCTs).
• Searched Embase, Medline, and conference abstracts for relevant studies.
• Analyzed primary outcomes (recurrence, chronic pain) and secondary outcomes (operating time, complications, reintervention, time to normal activities).

Main Results:

• No significant difference in recurrence or chronic pain between PHS and Lichtenstein repair.
• PHS demonstrated a significantly shorter time to return to normal activities (p=0.04).
• Operating time, composite complications, and surgical reintervention rates were similar between the two techniques.

Conclusions:

• Both PHS and Lichtenstein repair are comparable and acceptable techniques for inguinal herniorrhaphy.
• Further long-term studies on new mesh technologies are needed.
• Informed surgical decisions can be made regarding mesh choice for hernia repair.
