Analysis of risk factors affecting the development of peptic ulcer perforation: case-control study.

Aim: The aim of the to determine the risk factors associated with increased risk of peptic ulcer perforation (PUP).
Material and Methods: The demographic, clinic, and biochemical parameters of 65 patients (PUP group) who underwent PUP surgery at our clinic between June 2009 and September 2016 were compared with the data of 134 patients (control group) who underwent endoscopy at a gastroenterology clinic for dyspeptic complaints. The control group were matched at random in a 1 : 2 ratio with the PUP group. Univariate analyses were used to compare different variables and variables with clinical significance, and p ≤ 0.05 was used in the backward stepwise logistic regression model.
Results: This study included 65 patients with peptic ulcer perforation aged 17 to 92 years (PUP group) and 134 patients with dyspeptic complaints aged 18 to 87 years (control group). Univariate analysis showed that statistically significant differences were found between groups in terms of non-steroidal anti-inflammatory drugs usage ( p = 0.042; OR = 1.868), smoking ( p < 0.001; OR = 5.124), old age ( p = 0.003), low body mass index (BMI) ( p < 0.001), and low hemoglobin (Hb) ( p = 0.002). However multivariate analysis showed that increasing age ( p = 0.004; OR = 1.035), smoking ( p = 0.007; OR = 3.591), decreasing Hb ( p = 0.042; OR = 1.277), and decreasing BMI ( p < 0.001; OR = 1.669) were independent clinically significant risk factors for development of PUP.
Conclusions: This study showed that decreased BMI, decreased Hb, increased age, and smoking were independent risk factors for development of PUP. Thus, this group of patients needs particular attention paid to suggestive symptoms with early diagnosis and optimal management of peptic ulcer disease.
