Validation of Boey's scoring system in predicting short-term morbidity and mortality in peptic ulcer perforation peritonitis

Abstract

Aim: This study aims to assess the validation of Boey's scoring system in predicting short-term morbidity and mortality amongst patients with peptic ulcer perforation (PULP) peritonitis. Methodology: 110 patients with PULP peritonitis were included in this study. Boey's score was calculated based on three parameters, pre-operative shock, concomitant medical illness and duration of perforation >24 h. All patients with PULP were treated with exploratory laparotomy with peritoneal lavage and omental patch repair and the patients were then followed up throughout the data collection period to look for clinical outcomes. The main outcomes assessed were mortality and short-term morbidity (1 month). Data were analysed using SPSS (IBM, Delhi, India). Chi-square test was used to check for the association between the outcome variables and the categorised Boey's score. The level of statistical significance was assigned as a P < 0.05. Results: Amongst the 110 patients, half belonged to the age group of 31–50 years, and 90% were male. The most common site of perforation was the first part of duodenum (78%). The rate of mortality was 10%. With respect to the distribution of the Boey's score, the percentage of patients with Boey's score 0, 1, 2 and 3 was found to be 12.75%, 58.2%, 24.5% and 5%, respectively, and their corresponding mortality was found to be 0%, 4.7%, 25.9% and 40%, respectively. Their morbidity at 1 week was found to be 21.4%, 42.6%, 80% and 100%, respectively, and morbidity at 1 month was found to be 0%, 39.3%, 75% and 100%, respectively. Conclusion: There was a significant association between mortality and morbidity at 1 week and at 1 month with the distribution of Boey's score. This highlights the importance of Boey's score in determining the outcome amongst perforated peptic ulcer patients. Boey's score being an easily applicable score for day-to-day clinical practice can aid clinicians in predicting the outcome amongst perforated ulcer patients. Several studies have also shown better accuracy with Boey's scoring system when compared to the other scoring systems.
