Elective Repair of Spiegel Hernia: Laparoscopic vs Open Surgical Outcomes in 47 Cases
Overview
This retrospective cohort study analyzed 47 patients undergoing elective repair of Spiegel hernia, comparing laparoscopic transabdominal preperitoneal (TAPP) and open surgical approaches. The study highlights diagnostic challenges, surgical techniques, and postoperative outcomes including complications and recurrence rates.
Background
Spiegel hernia is a rare anterior lateral abdominal wall hernia occurring along the semilunar line, often interstitial and difficult to diagnose clinically. Imaging modalities such as ultrasonography and computed tomography are essential for accurate diagnosis. Due to a high risk of strangulation and incarceration, elective surgical repair is recommended. Minimally invasive laparoscopic techniques have gained preference over the past two decades.

Key Findings
Spiegel hernias are often interstitial, complicating clinical diagnosis and necessitating imaging such as USG and CT.
Elective repair is advised due to a 15-24% risk of strangulation associated with narrow hernia necks.
Laparoscopic TAPP repair involves mesh placement in the preperitoneal space with absorbable tackers and peritoneal flap closure.
Open repair involves external oblique aponeurosis incision, sac dissection, and mesh placement with similar overlap and fixation.
Choice of surgical approach depends on patient factors, presentation type, and surgeon preference; emergency cases favor open surgery.
Postoperative follow-up includes monitoring for complications per Clavien-Dindo classification and assessment of chronic pain and recurrence.
Clinical Implications
Clinicians should maintain a high index of suspicion for Spiegel hernia in patients with lateral abdominal wall bulges and utilize imaging for diagnosis. Elective surgical repair, preferably laparoscopic when feasible, can reduce the risk of strangulation and improve recovery. Careful patient selection and surgeon expertise are critical for optimal outcomes.
Conclusion
This study reinforces the importance of imaging in diagnosing Spiegel hernias and supports elective repair using either laparoscopic or open techniques tailored to patient and clinical factors. Both approaches demonstrate effective outcomes with low recurrence when performed by experienced surgeons.
