Does the approach to the groin make a difference in hernia repair?

Area of Science:

• Surgical techniques
• Hernia repair
• Minimally invasive surgery

Background:

• Both laparoscopic and open preperitoneal hernia repair techniques utilize the preperitoneal space.
• The study aimed to determine if the surgical approach to the inguinal canal impacts patient outcomes.

Purpose of the Study:

• To compare the outcomes of different surgical approaches for inguinal hernia repair.
• To evaluate the impact of surgical approach on inflammatory markers, pain, complications, and recurrence rates.

Main Methods:

• 160 patients with inguinal hernia were randomly assigned to four groups: open anterior, open preperitoneal, laparoscopic transabdominal preperitoneal, and laparoscopic total extraperitoneal.
• Key outcome measures included serum levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), Visual Analog Scale (VAS) pain scores at 6 and 48 hours, complications, and recurrence rates.

Main Results:

• Serum IL-6 levels were significantly lower in the open preperitoneal, transabdominal preperitoneal, and total extraperitoneal groups compared to the open anterior group (P < 0.01).
• Tumor necrosis factor-alpha (TNF-alpha) levels were highest in the open anterior approach group.
• Pain scores were lower in patients who underwent posterior approach techniques compared to the open anterior approach.

Conclusions:

• Surgical access to the inguinal canal via the preperitoneal space is associated with reduced inflammation and pain.
• The preperitoneal approach appears to be a less invasive surgical option for inguinal hernia repair compared to the transinguinal anterior approach.
