Abstract
INTRODUCTION AND IMPORTANCE: Laparoscopic surgery is recommended to treat recurrent inguinal hernia (IH). Single-incision laparoscopic surgery transabdominal pre-peritoneal (SILS-TAPP) has been an option for IH repair but few studies on the application of this method for recurrent IH was conducted. We aimed to report our experience of SILS-TAPP for recurrent IH and the long-term outcomes of this technique. CASE PRESENTATION: Ten patients of recurrent IH, including three multiple recurrences, were successfully treated with SILS-TAPP. Previous surgeries were Bassini and Lichtenstein's procedures. No perioperative complications were observed; neither additional trocar nor conversion to open surgery was needed. Median operation time was 65 (range: 45-95) minutes. Post-operative pain lasted for two to three days. Neither long-term complications nor recurrence was seen until the median follow-up time of 37 (range: 16-53) months. CLINICAL DISCUSSION: Although the surgical procedure of hernia repair of SILS-TAPP was the same as conventional TAPP, the manipulation of the instrument was technically challenging. This surgical method should be done by an SILS expert with application of several surgical tips to overcome difficulties adhering to single-port surgery. Also, meticulous and patient dissection of the inguinal site is suggested. CONCLUSION: SILS-TAPP is safe and feasible to repair recurrent inguinal hernia. However, it should be done by experienced surgeons.
