    Abstract:
    INTRODUCTION: Spigelian hernias (SH) are rare intraparietal abdominal wall hernias occurring just medial to the semilunar line. Several small series have reported on laparoscopic SH repair and both totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) approaches have been described. However, there are limited outcome data including both of these techniques. We present the largest series to date of laparoscopic SH repair comparing both popular approaches. METHODS: Consecutive patients (n = 77) undergoing laparoscopic SH repair from 2009 to 2019 were identified from a prospectively managed quality database. All procedures were performed at a single institution. Patients were divided based on laparoscopic approach used, TEP group (n = 37) and TAPP group (n = 40). Comparison of patient demographics, surgical characteristics, and post-operative complications between TAPP and TEP groups was made using the Wilcoxon rank-sum and Fisher's exact tests. RESULTS: Individuals undergoing TAPP had higher mean BMI (29.3 ± 5.4 vs. 26.3 ± 5.6 kg/m2; p = 0.019) and were more likely to have had prior abdominal surgery (65% vs 24.3%, (p < 0.001). Mean procedure length was 77 ± 45 min for TAPP repairs and 48 ± 21 for TEP repairs (p = 0.001). TAPP repairs had a significantly longer median LOS than TEP (25 vs. 7 h; p < 0.001). Days of narcotic use were significantly shorter after TEP repair than for TAPP (0 vs. 3; p = 0.007) and return to ADL was significantly shorter after TEP repair than for TAPP (5 vs. 7 days; p = 0.016. There were no significant differences in readmission, reoperations, SSI, or recurrence between the two groups. CONCLUSION: Our large series revealed that both preperitoneal laparoscopic approaches, TEP, and TAPP, for SH repair are equally safe, effective, and can be performed on an outpatient basis. Therefore, we suggest that the approach used for repair should be based on surgeon experience, preference, and individual patient factors.
