INGUINAL HERNIA:RECENT APPROACHES

A hernia represents a pathological condition characterized by the protrusion of visceral structures through a congenital or acquired defect in the musculofascial layer intended to contain them. Most abdominal hernias involve the displacement of intra-abdominal organs or adipose tissue through regions of compromised myofascial integrity in the abdominal wall. Herniation may develop insidiously due to age-related cumulative structural degeneration of connective tissues or acutely secondary to traumatic injury, iatrogenic factors (e.g., post-surgical dehiscence), or congenital fascial defects such as patent processus vaginalis.An inguinal hernia, the most prevalent variant, occurs when abdominal contents—typically omentum or intestinal segments—herniate through a compromised region of the inguinal canal, often due to weakness in the transversalis fascia or conjoint tendon. Clinical manifestations may include a palpable, reducible mass in the inguinal region accompanied by discomfort exacerbated by Valsalva maneuvers (e.g., coughing, heavy lifting) due to transient increases in intra-abdominal pressure. While symptomatic presentations frequently involve localized pain or pressure, many hernias remain asymptomatic with incidental detection, underscoring the importance of vigilant physical examination for timely intervention. An inguinal hernia, while not inherently life-threatening, represents a persistent anatomical defect with negligible potential for spontaneous resolution1. Left unaddressed, it carries a risk of progression to complications such as incarceration or strangulation, wherein herniated viscera become entrapped within the fascial defect, precipitating vascular compromise, ischemic necrosis, and potential perforation—a surgical emergency. Consequently, symptomatic presentations (e.g., localized pain, progressive enlargement, or functional impairment) typically warrant elective herniorrhaphy to mitigate morbidity. This procedure, involving reinforcement of the inguinal floor with synthetic mesh or autologous tissue, ranks among the most frequently performed interventions in general surgery. Contemporary approaches prioritize minimally invasive techniques, such as laparoscopy, to reduce postoperative recovery time and recurrence rates, though open repair remains indicated in select cases. Abdominal wall hernias are common, with a prevalence of 1.7% for all ages and 4% for those aged over 45 years. Inguinal hernias account for 75% of abdominal wall hernias, with a lifetime risk of 27% in men and 3% in women2. In the past decade hernia surgery has been challenged by two new technologies: by laparoscopy, which has attempted to change the traditional open operative techniques, and by prosthetic mesh, which has achieved much lower recurrence rates. The demand by health care providers for increasingly efficient and costeffective surgery has resulted in modifications to pathways of care to encourage more widespread adoption of day case, outpatient surgery, and local anaesthesia3.
