Open vs laparoscopic hernia repair in the brazilian public health system. An 11-year nationwide population-based study

Abstract

– Background – Abdominal wall hernia is one of the most common surgical pathologies. The advent of minimally invasive surgery raised questions about the best technique to be applied, considering the possibility of reducing postoperative pain, a lower rate of complications, and early return to usual activities. Objective – To evaluate the frequency of open and laparoscopic hernioplasties in Brazil from 2008 to 2018, analyzing the rates of urgent and elective surgeries, mortality, costs, and the impact of laparoscopic surgical training on the public health system. Methods – Nationwide data from 2008 to 2018 were obtained from the public health registry database (DATASUS) for a descriptive analysis of the selected data and parameters. Results – 2,671,347 hernioplasties were performed in the period, an average of 242,850 surgeries per year (99.4% open, 0.6% laparoscopic). The economically active population (aged 20-59) constituted the dominant group (54.5%). There was a significant reduction (P<0.01) in open surgeries, without a compensatory increase in laparoscopic procedures. 22.3% of surgeries were urgent, with a significant increase in mortality when compared to elective surgeries (P<0.01). The distribution of laparoscopic surgery varied widely, directly associated with the number of digestive surgeons. Conclusion – This study presents nationwide data on hernia repair surgeries in Brazil for the first time. Minimally invasive techniques represent a minor portion of hernioplasties. Urgent surgeries represent a high percentage when compared to other countries, with increased mortality. The data reinforce the need for improvement in the offer of services, specialized training, and equalization in the distribution of procedures in all regions.
