P-EGS26 Outcomes of Surgical Treatment for Perforated Peptic Ulcer in a non-Upper Gastrointestinal Surgery Centre

Background Perforated peptic ulcer (PPU) remains a common surgical emergency worldwide requiring surgical intervention. Although commonly performed, morbidity and mortality rate remained high. This study aimed to analyze the factors that contribute to the outcome of PPU surgery in a non-upper gastrointestinal surgery center in Malaysia. Methods Data were collected by retrospective review of all PPU surgeries done throughout the year 2020, looking into various preoperative, intraoperative, and postoperative details. Results In this study, we have a total of 24 PPU patients underwent surgery resulted in 7 (29.2%) deaths. Majority of our subjects were elderly (median age 65 years, IQR 48.5 – 73.0) with 4 (16%) being of ASA (American Society of Anesthesiologist) category 3 - 4. The most common cause of death was uncontrolled systemic infection in 4 patients (57.1%), followed by 2 (28.6%) fatal arrhythmia and 1 (14.3%) massive upper gastrointestinal bleed. Our analysis found that size of perforation ≥ 30mm (OR = 0.18, 95%CI 0.08 - 0.44), and postoperative complications (OR = 12.5, 95%CI 1.6 – 97.6) were significantly associated with a higher postoperative death. Low serum albumin level (mean 34.3 ± 9.1g/L), negative base excess level (mean -3.28 ± 4.89), and prolonged interval between admission and commencement of surgery (median 750 mins, IQR 258 – 2218) were all significantly associated with increased mortality post PPU surgeries.  Conclusions This study highlighted to us various perioperative factors which could potentially be modifiable thus necessary measures can be taken in the future to ensure a better operative outcome of PPU surgery.
