Purpose: The use of open intra-peritoneal onlay mesh repairs (O-IPOMs) for treating medium/large incisional ventral hernias has come into question due to the development of minimally invasive and sublay procedures. This study aimed to identify factors that are associated with the use of O-IPOMs in France. Methods: We analysed prospectively collected data from the French Hernia Registry on incisional ventral hernia repairs (IVHR) for hernias ≥ 4 cm in width. Results: We obtained data for 2261 IVHR (from 11/09/2011 to 30/03/2020): 733 O-IPOMs and 1,528 other techniques. We found that the O-IPOMs were performed on patients with more patient-related risk factors compared with the other techniques. Specifically, there was a higher proportion of patients with ASA III/IV (40.47% vs. 28.02%; p < 0.00001) and at least one patient-related risk factor (66.17% vs. 58.51%; p = 0.0005). Of the 733 O-IPOMs, 195 used Ventrio ST™ (VST), the most commonly used mesh for such IPOMs in our database; the other 538 O-IPOMs used other meshes (OM). The VST subgroup had a higher proportion of patients with ASA III/IV (52.58% vs. 36.07%; p < 0.0001) and on anticoagulants (26.04% vs. 18.41%; p = 0.0229) compared with the OM subgroup; they also had a lower recurrence rate after 2 years (5.83% vs. 15.41%; p = 0.008). However, large (≥ 10 cm) or lateral defects were more common in the OM subgroup, and their mesh/defect area ratio was lower. Conclusion: O-IPOMs were performed on patients with more comorbidities and/or complex incisional hernias compared with other techniques. [ABSTRACT FROM AUTHOR]

Introduction: Several quality indices have been set up for evaluating the impact of the reduction of the length of stay (LOS), such as the 30-day unplanned readmission (UR30) rate. The main goal of our study was to analyze the UR30 following groin hernia repair (GHR), primary- (PVHR), and incisional ventral hernia repairs (IVHR). Methods: A French registry-based multicenter study was conducted using prospective data from all consecutive patients registered from 2015 to 2021. Results: The overall incidence of UR30 was 1.32%. This included 160/18,042 (0.87%) for GHR, 41/4012 (1.02%) for PVHR, and 145/3754 (3.86%) for IVHR. The leading cause of UR30 was postoperative complications (POC). The nature of the predominant complications varied among the three categories. The correlation between UR30 and POC (and risk factors for POC) was strong in GHR but was not in IVHR due to a 'protective' longer LOS in this subgroup. As the LOS has decreased over the last years, this has 'mechanically' resulted in an increase in the occurrence of UR30, but not in a rise of POC, neither in volume nor in severity. The reduction of LOS just shifted the problem from inpatient to outpatient settings. Conclusion: Since the steady development of day-care surgery, the prevention of the UR not only hinges on the prevention of the POC but newly on a better organization of outpatient care which is currently a huge challenge due to a GPs' and nurses' shortage in France.

Purpose: To assess the rate of late chronic postoperative inguinal pain (CPIP) after groin hernia repair in patients with different categories of preoperative VRS (Verbal Rating Scale) pain and to make a pragmatic evaluation of the rates of potentially surgery-related CPIP vs. postoperative continuation of preexisting preoperative pain. Methods: Groin pain of patients operated from 01/11/2011 to 01/04/2014 was assessed preoperatively, postoperatively and at 2-year follow-up using a VRS-4 in 5670 consecutive groin hernia repairs. A PROM (Patient Related Outcomes Measurement) questionnaire studied the impact of CPIP on the patients' daily life. Results: Relevant (moderate or severe VRS) pain was registered preoperatively in 1639 of 5670 (29%) cases vs. 197 of 4704 (4.2%) cases at the 2-year follow-up. Among the latter, 125 (3.7%) cases were found in 3353 cases with no-relevant preoperative pain and 72 (5.3%) in 1351 cases with relevant preoperative pain. Relevant CPIP consisted of 179 (3.8%) cases of moderate pain and 18 (0.4%) cases of severe pain. The rate of severe CPIP was independent of the preoperative VRS-pain category while the rate of moderate CPIP (3.1%, 3.4%, 4.1%, 6.8%) increased in line with the preoperative (none, mild, moderate, and severe) VRS-pain categories. The VRS probably overestimated pain since 71.6% of the relevant CPIP patients assessed their pain as less bothersome than the hernia. Conclusion: At the 2-year follow-up, relevant CPIP was registered in 4.2% cases, of which 63.5% were potentially surgery-related (no-relevant preoperative pain) and 36.5% possibly due to the postoperative persistence of preoperative pain. The rate of severe CPIP was constant around 0.4%. [ABSTRACT FROM AUTHOR]
