[Developments in inguinal hernia based on newly introduced intervention techniques in the North Rhine district]

Area of Science:

• Surgical Innovation
• Hernia Repair Techniques
• Minimally Invasive Surgery

Context:

• German inguinal hernia surgery evolved over a decade, moving from conventional methods to video-assisted minimally invasive techniques and Lichtenstein repair.
• A comprehensive quality surveillance study documented 173,923 patients undergoing inguinal hernia repair in the North-Rhine area from 1991 onwards.

Purpose:

• To analyze the trends in surgical approaches for inguinal hernia repair in Germany over a ten-year period.
• To document the adoption rates of new techniques such as transabdominal preperitoneal (TAPP) repair, totally extraperitoneal (TEP) repair, and Lichtenstein repair.
• To assess the complication rates associated with different inguinal hernia repair methods.

Summary:

• The study observed a significant shift from traditional Shouldice and Bassini repairs to TAPP, TEP, and Lichtenstein repairs between 1993 and 1999.
• While minimally invasive techniques (TAPP, TEP) and Lichtenstein repair adoption increased, conventional methods like Shouldice repair remained prevalent.
• Observed complication rates included hematoma/seroma formation (3.78%), wound infection (1.15%), testicular edema (0.37%), and scrotal edema (0.64%). No reduction in operations for recurrent hernias was noted.

Impact:

• Provides valuable data on the changing landscape of inguinal hernia surgery in Germany, highlighting the integration of advanced surgical procedures.
• Documents the increasing utilization of minimally invasive and mesh-based repair techniques.
• Highlights the need for continued monitoring of recurrence rates and complication profiles with evolving surgical practices.
