Abstract
PURPOSE: To investigate the impact of the COVID-19 pandemic on the clinical impact of the clinical outcomes of robotic inguinal hernia repair. METHODS: Patients who underwent RIHR 2 years before and after March 10, 2020, were included in this retrospective study and assigned accordingly to the pre- or post-COVID group. Pre-, intra-, and postoperative variables including patients' demographics, hernia characteristics, complications, and hernia recurrence rates were compared between groups. RESULTS: 183 (94.5% male) and 141 (96.4% male) patients were assigned to the pre- and post-COVID groups, respectively. Patient demographics and medical comorbidities did not differ between groups. Operative time was approximately 40 min longer in the post-COVID group (p < 0.001) with higher rates of bilateral IHR (pre-COVID: 30.1% vs. post-COVID: 46.4%, p = 0.003). Mesh material differed between groups with predominance of polyester mesh in the pre-COVID group vs. polypropylene in the post-COVID one. Median hospital length of stay (LOS) was 0 days in both groups, and same-day discharge rates were 93.4% pre-pandemic and 92.8% post-pandemic (p = 0.09). There were no pulmonary complications recorded in either group or no cases of COVID-19 detected within two weeks postoperatively in the post-COVID group. Seromas were more frequent in the post-COVID group (pre-COVID: 2 vs. post-COVID: 8, p = 0.018) and no hernia recurrences were recorded. CONCLUSION: This is the first study to describe the impact of COVID-19 on RIHR. Clinical outcomes and hernia-specific complications were not impacted by the COVID-19 pandemic.
