Risk factors for conversion in laparoscopic totally extraperitoneal inguinal hernioplasty


Background: Conversion is a surgical concern because the surgical technique can change during surgery. Surprisingly, there is no study in the literature on the causes and risk factors leading to conversion in laparoscopic total extraperitoneal inguinal repair (TEP). There is also no consensus on the prevention and causes of this condition in TEP. The aim of this study was to evaluate the risk factors underlying the development of conversion during TEP. Materials and Methods: We recruited 962 consecutive patients who underwent TEP between May 2016 and May 2021. All data were collected retrospectively. The outcomes of patients who converted to open surgery were compared with those without conversion. Multivariate analysis identified independent risk factors for conversion. Results: The overall incidence of conversion was 4.05% (n= 39). The median age was 42 years (18 to 83) and body mass index was 25.2 kg/m2 (15.67 to 32.9). Significant clinical factors associated with conversion included old age, American Society of Anesthesiologists (ASA) score, large peritoneal tear (PT), Charlson comorbidity index, previous surgery, large hernial defects, presence of scrotal hernia, and the defect size of inguinal hernia. Multivariate analysis identified independent risk factors for conversion: large hernial defect, large PT, previous lower abdominal surgery, previous hernia surgery, and scrotal hernia. Conclusion: Conversion is a minor complication seen during TEP and its incidence varies depending on many factors. Previous lower abdominal surgery and a large PT carries a 6-fold increased risk for conversion from laparoscopic to open surgery during TEP
