A comparative analysis of trans-abdominal pre-peritoneal repair in uncomplicated vs complicated inguinal hernia repair.

INTRODUCTION

Trans-abdominal pre-peritoneal (TAPP) repair is one of the standard techniques for laparoscopic repair of groin hernias. Literature has shown that both total extraperitoneal (TEP) and TAPP are equally effective with similar outcomes but TAPP has an advantage over TEP as there is more working space, and it provides access to the opposite side for repair of occult hernias. We reviewed our experience of TAPP repair in complicated groin hernias and compared the outcomes with uncomplicated groin hernia.

METHODS

Patients undergoing TAPP repair from January 2004 to December 2019 were analyzed, and divided into two groups-I uncomplicated and II complicated groin hernia.

RESULTS

TAPP repair was performed in 820 patients, of which 70.3% had uncomplicated and 29.7% patients had complicated hernias. Occult hernia was detected in 61 patients. The intra-operative complications (16.8% vs 1.3%) and conversions (2.4%) were higher in complicated hernias. Laparoscopic assisted repair was used in 16.8% patients with complicated hernias. The incidence of post-operative complications (62.1% vs 17.3%; P value <.01) were significantly higher in complicated groin hernia patients. The median follow-up was 15 months; only three patients in the uncomplicated hernia group developed recurrence, and chronic groin pain was higher in the complicated hernia repair patients (P > .05) at 6 months.

CONCLUSION

Although operative time, incidence of intra-operative and post-operative complications (albeit minor in nature), and conversions to open are higher after TAPP repair for complicated groin hernias, the short-term outcomes (hematoma, mesh infection) as well as long-term outcomes (chronic groin pain, port site hernia and recurrence) are not different when compared with uncomplicated hernias. TAPP repair can be used in both complicated and uncomplicated groin hernias with similar short-term and long-term outcomes, albeit with a slightly higher incidence of minor complications in complicated hernias. This can be taken into consideration while operating on patients with complicated hernias and taking informed consent.
