Elective Laparoscopic Totally Extraperitoneal Repair For Spigelian Hernia: A Case Series Of Four Patients

IntroductionSpigelian hernia (SH) is uncommon. Clinical diagnosis may be difficult, but computed tomography (CT) can help to establish the diagnosis. Laparoscopic repair is increasingly performed because it is associated with low morbidity rates. Laparoscopic approaches include transabdominal preperitoneal (TAPP), intraperitoneal onlay mesh (IPOM), and totally extraperitoneal (TEP). Here, we report our experiences of TEP repair for SH.MethodsA retrospective review was performed on all patients with SH who underwent elective laparoscopic TEP repair from 2007 to 2017 at Tung Wah Hospital, Hong Kong.ResultsFour patients with SH were identified in the study period: three with a preoperative diagnosis of SH confirmed by CT scan and one diagnosed incidentally during TEP repair for inguinal hernia. The patients' mean age was 66.8years (range, 55.0-82.0years). The mean BMI was 22.8kg/m(2) (range, 20.8-23.6kg/m(2)). The mean size of the SH defect was 2.0cm (range, 0.5-3.0cm). The mean operative time was 59min (range, 40-86min). Concomitant direct inguinal hernia was found in one patient and repaired simultaneously. All patients were discharged on postoperative day 1. One patient developed seroma, which subsided on conservative management. At a mean follow-up of 36months (range, 2-108months), there was no recurrence.ConclusionLaparoscopic repair for SH is preferred over the open approach as it is associated with a low morbidity rate and a short hospital stay. In our experience, TEP technique is safe and effective in laparoscopic SH repair.
