Laparoscopic surgery and mortality in perforated peptic ulcer (correlation and regression

Abstract

Aim of the study is to evaluate the relationship between the number of laparoscopic operations and mortality in patients with perforated peptic ulcer. Materials and methods: The functional relationships between the number of performed laparoscopic operations and the levels of hospital and postoperative mortality were studied based on the analysis of the results of surgical treatment of patients with a perforated ulcer in 2018. Results: An analysis of the functional relationships between the number of laparoscopic operations performed and mortality was carried out based on the results of primary statistical information (2 189 patients with a perforated ulcer). Strong direct correlations have been established, which can be most reliably described within the framework of polynomial regression models (r2 = 0.917 and r2 = 0.889). Conclusion: An assessment of trends in the reduction in hospital and postoperative mortality with an increase in number of laparoscopic operations will be determined only with standardized approaches to the usage of minimally invasive technologies in all areas of the Russian Federation.
