However, differences in the origin of the fat tissue entrapped within the hernia defect suggest the existence of two distinct subtypes. Notably, intraoperative differences observed between supravesical hernia (SH) and conventional medial hernia (CMH) indicate distinct pathogenetic mechanisms underlying each subtype. This study aims to demonstrate that Type M hernia comprises two pathogenetically distinct subtypes, supported by a comprehensive literature review.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>To investigate the distinct pathogenesis of SH and CMH, we retrospectively analyzed 138 cases of transabdominal preperitoneal (TAPP) repair performed between January 2023 and December 2024.

In contrast, in 44 of the 49 CMH cases (90%), it primarily originated from the deep layers (Layer D).

Intraoperative findings suggest that SH develops due to traction forces acting on the abdominal wall, whereas CMH is primarily attributed to increased intra-abdominal pressure.
