Abstract Background Flank hernias are uncommon, surgical treatment is challenging and the minimally-invasive approach not always feasible. The aim of this study was to report the safety and feasibility of the robotic-assisted repair. Methods The study was approved by the local ethic committee (2019–01132 CE3495). A retrospective search on a prospectively collected dataset including demographic and clinical records on robotic surgery at our institution was performed to identify patients treated for a flank hernia. Patients were followed-up 6 months. Results From January 2018 to December 2019, out of 190 patients who underwent robotic-assisted hernia surgery, seven with incisional flank hernia were included. Median age was 69.0 years (IQR 63.2–78.0), BMI was 27.3 kg/m2 (IQR 25.8–32.3) and two patients were male (29%). All patients were referred to surgery because of pain, whereas one of them described recurrent episodes of small bowel obstruction. The median hernia defect measured 25 mm ((IQR 21–40), median mesh diameter was 10 cm (IQR 10–12.5) and median operative time was 137 min (IQR 133–174). No intraoperative complication occurred. Postoperatively, one patient developed a pneumonia, which required antibiotics. Length of hospital stay was 4.0 days (IQR 3.0–7.7). Six months after surgery, neither recurrence nor chronic pain were recorded. Conclusions Robotics in abdominal wall hernia surgery remains a matter of debate, despite a growing interest from the surgical community. In our reported experience with flank hernias, we found the robotic-assisted approach to be safe and feasible for the treatment of this uncommon clinical entity.
