Nationwide analysis of inpatient laparoscopic ventral hernia repair in Italy from 2015 to 2020

Since 2010, several guidelines and consensus papers have been proposed to support surgeons in the decision-making process (Cuccurullo et al. in Hernia 17(5):557–566, 2013; Silecchia et al. in Surg Endosc 29:2463–2484, 2015; Bittner et al. in Surg Endosc 33(11):3511–3549, 2015) with the conclusion that laparoscopic repair (LR) has gained popularity in the treatment of IH. To date, however, it is not yet clear as to the uptake of LR for IH on national basis. Only dated studies encompassing of all types of incisional hernia repairs are available in literature (Bisgaard et al. in Br J Surg 96:1452–1457, 2009). The aim of our study is to present a snapshot of Italian data for LR of ventral hernias, over a 6 years period, including volume of LR, procedural features and major postoperative outcomes. Data were extracted from the Italian Hospital Information System (HIS) that collects clinical and administrative information regarding each hospital admission of every patient discharged from any hospital in Italy. Using Hospital Discharge records regional Databases (HDD), all laparoscopic ventral hernia procedures carried out in public and private hospitals between 2015 and 2020, in patients over 18 years and resident in Italy, were collected based on diagnosis and procedure codes. The National Agency for Regional Health Services (AgeNaS) oversees the management and analysis of data. All hospital admissions that occurred between 2015 and 2020 were analyzed. A total of 154,546 incisional hernia repairs were performed in Italy from 2015 to 2020. Of these, 20,789 (13.45%) were minimally invasive repairs. The number of procedures performed increased significantly over time, constituting 11.96 and 15.24% of all procedures performed in 2015 and 2020 respectively. However, considering the whole period, the mean annual change was—5.58% (CI − 28.6% to 17.44%; p < 0.0001). Urgent minimally invasive repairs were performed in 1968 cases (1.27%). The absolute rate of laparoscopically treated patients needing an urgent surgical procedure increased overtime (from 7.36% in 2015 to 13.418% in 2020). The mean annual change registered over the whole period was 7.42%. 92% (CI − 0.03 to 14.09%; p < 0.0001). However, when considering the period from 2015 to 2019, the mean annual change was 10.42% (CI 6.35 to 14.49%; p < 0.0001). To our knowledge this is the first nationwide Italian report presenting the national workload of surgical units and the main perioperative features of minimally invasive surgery for ventral hernia repairs.
