ABSTRACT
PURPOSE: The TransREctus sheath PrePeritoneal procedure (TREPP) was introduced as an alternative open and preperitoneal technique for inguinal hernia mesh repair, demonstrating safety and efficacy in retro- and prospective studies. However, little is known about the technique's inherent learning curve. In this study, we aimed to determine TREPP learning curve effects after its implementation in high-volume surgical practice. METHODS: All primary, unilateral TREPP procedures performed in the first three years after implementation (between January 2016 and December 2018) were included out of a large preconstructed regional inguinal hernia database. Data were analyzed on outcome (i.e., surgical complications, hernia recurrences, postoperative pain). Learning curve effects were analyzed by assessing outcome in relation to surgeon experience. RESULTS: In total, 422 primary, unilateral TREPP procedures were performed in 419 patients. In three patients a unilateral TREPP procedure was performed on both sides separated in time. A total of 99 surgical complications were registered in 83 procedures (19.6% of all procedures), most commonly inguinal postoperative pain (8%) and bleeding complications (7%). Hernia recurrences were observed in 17 patients (4%). No statistically significant differences on outcome were found between different surgeon experience (< 40 procedures, 40-80 procedures, > 80 procedures). CONCLUSION: Implementation of TREPP seems not to be associated with a notable increase of adverse events. We were not able to detect a clear learning curve limit, potentially suggesting a relatively short learning curve among already experienced hernia surgeons compared to other guideline techniques.
ABSTRACT
PURPOSE: Results of the most commonly used inguinal hernia repair techniques often originate from expert centers or from randomized controlled studies. In this study, we portray daily-practice results of a high-volume, regional surgical group in the Netherlands, comparing TREPP (open (posterior) transrectus sheath pre-peritoneal) with Lichtenstein (open anterior) and TEP (endoscopic (posterior) totally extraperitoneal). We hypothesize that the TREPP shows more favorable outcome compared to the current gold standard procedures: TEP and Lichtenstein. METHODS: Between January 2016 and December 2018, 3285 consecutive patients underwent surgical treatment and were included for analysis. The outcome measures were postoperative pain, recurrence rate and other surgical complications. Propensity-score matching was used to address potential selection bias. RESULTS: After propensity-score matching, there was no statistically significant difference in postoperative pain in the TREPP group compared to the Lichtenstein group (TREPP 7.3% versus Lichtenstein 6.3%; p = 0.67) nor in TREPP compared to TEP (TREPP 7.4% versus TEP 4.1%; p = 0.064). There was no statistically significant difference in recurrences in the TREPP group compared to Lichtenstein (3.8% vs 2.5%; p = 0.42), nor in the TREPP versus TEP comparison (3.9% vs 2.8%; p = 0.55) CONCLUSION: This study compares TREPP with Lichtenstein and TEP in the presence of postoperative pain, recurrences and other adverse outcomes. After propensity-score matching, no statistically significant difference in postoperative pain or recurrences remained between either TREPP compared to Lichtenstein, or TREPP compared to TEP. Based on these results, TREPP, Lichtenstein and TEP showed comparable results in postoperative pain, recurrences and other surgical site complications.

Two adolescents, on immunosuppressive therapy for graft-versus-host disease, developed hemophagocytic lymphohistiocytosis (HLH) after varicella zoster virus (VZV) reactivation. In the absence of dermatome restricted characteristic skin lesions, VZV reactivation was not immediately recognized and treatment with acyclovir was delayed. The first patient developed optical neuritis and died 2 months after the VZV episode due to massive intracranial hemorrhage. The second patient presented with severe abdominal pain and pancreatitis, followed by atypical skin eruptions, which prompted a faster diagnosis. Both patients recovered from their HLH, the first patient being successfully treated with immunosuppressive agents and the second with VZV treatment only. These two cases demonstrate the difficulties in recognizing VZV reactivation, and in order to start adequate and timely treatment, the need to consider VZV as a possible cause of HLH in severely immunocompromised patients.
