[Peptic ulcer perforation: an analysis of risk factors].
BACKGROUND
Despite decreasing incidence of peptic ulcer disease, peptic ulcer perforation remains a source of mortality. This retrospective study was performed to find riskfactors for mortality and to construct a score that predict outcome for patients with peptic ulcer perforation.


METHODS
A review of94 patients operated (primer ciosure and omentoplasty) for perforated peptic ulcer in Iast ten years was undertaken to study. lndependent risk factors for mortality were found with Iinear regression analysis and risk score was constructed using standardized coefficients of risk factors.


RESULTS
Acute renal failure (ARF) (p < 0,00 1 ), treatment delay more than 48 hours (> =48 hours) (p = 0,203 ) and age greater than 60 years (> 60 years) (p = 0, 199) were found signijicant factors independently injuencing mortality. The risk score was (Risk score = (ARF)XO,497 + (> =48 hours)XO,203 + (>60years)XO,199). The overall predictive accuracy of risk score was%95.


CONCLUSIONS
Treatment delay and related acute renal failure and advanced age are determining factors for survival after ulcer perforation. Delay of treatment may be only changeable factor for mortality. lt is ciear that, the early diagnosis and treatment aredecreasing operative mortality of peptic ulcer perforation. Every effort to decrease the mortality should be this mannei:
